[Overall configuration]
1 is a diagram showing an example of the configuration of an information providing system 1 using an information providing device 100 according to an embodiment. The information providing system 1 includes, for example, the information providing device 100, a collection device 200, an abnormality detection device 300, a plurality of server devices each storing different types of monitoring information related to a power plant facility to be monitored (hereinafter, monitoring information), one or more first terminal devices TM1 having data input, control, and display functions used by an operator (monitor) of the power plant to be monitored, and one or more second terminal devices TM2 having data input, control, and display functions used by a repairman who performs repair, inspection, etc. of the power plant facility to be monitored. The information providing device 100, the collecting device 200, the anomaly detection device 300, the multiple server devices, one or more first terminal devices TM1, and one or more second terminal devices TM2 are connected to be able to send and receive information via a network NW including a LAN (Local Area Network), a WAN (Wide Area Network), etc., but connections are not limited to these networks, and they can also be connected via a network that performs one-way communication to send and receive data. Hereinafter, repairs, inspections, etc. are also referred to as "maintenance", and when there is no distinction between operators and repair personnel, they will be simply referred to as "users".

The first terminal device TM1 and the second terminal device TM2 are realized by a personal computer equipped with output devices such as a display and a speaker, and input devices such as a keyboard, a mouse, and a touch panel, or a smartphone or tablet computer equipped with an input/output device that combines a display and a touch panel. Hereinafter, when there is no need to distinguish between the first terminal device TM1 and the second terminal device TM2, they will simply be referred to as "terminal device TM".

In this embodiment, the case will be described where the equipment to be monitored is power equipment such as a power plant and each piece of equipment in the power plant (e.g., a power generation energy source control device, a turbine, a generator, a transformer, etc.). The collection device 200 is a device that collects information on the measured power generated by the power plant and information measured by measuring devices installed in each piece of equipment in the power plant at a predetermined time interval. Hereinafter, the information collected by the collection device 200 will be referred to as "measurement information". The measurement information includes, for example, information indicating the measurement date and time, information indicating the target equipment to be measured, information that can identify the target equipment (hereinafter, target equipment ID), measurement value data, image data of the target equipment, and sound data of collected environmental sounds around the target equipment. The target equipment ID is an example of "equipment identification information".

The information included in the measurement information is an example and is not limited to this. The measurement information may include some of the information described above, or may include other data (e.g., pressure and humidity information, etc.). For example, image data may be acquired when an apparent change occurs in the target device (at the time of installation, at the time of damage, at the time of repair, at the time of completion of repair, etc.) and may be included in the measurement information. In addition, in the information providing system 1 shown in FIG. 1, the collection device 200 collects measurement information from one power plant, but this is not limited to this. The collection device 200 of the information providing system 1 may collect measurement information from multiple power plants.

The abnormality detection device 300 detects abnormalities in the power plant by comparing the plant data indicated by the measurement information collected by the collection device 200 with a reference value and a moving average processing value of the plant data based on the monitoring information stored in the log information database DB1 described below. The abnormality detection device 300 may detect at least one of an abnormality in the power plant and a sign of an abnormality in the power plant. Below, a case where the abnormality detection device 300 detects both an abnormality in the power plant and a sign of an abnormality in the power plant will be described.

The information providing system 1 may include multiple collection devices 200 or multiple anomaly detection devices 300 corresponding to each server device.

In this embodiment, the information providing system 1 includes six server devices. The six server devices are, for example, a log information server device SV1, a facility management information server device SV2, an event information server device SV3, a maintenance information server device SV4, a spare parts information server device SV5, and a user information server device SV6. Hereinafter, when the servers are not distinguished from one another, they will simply be referred to as "server devices SV". The server devices SV store dynamic information such as measurement information collected by the collection device 200 and static information such as a facility ledger of facilities installed in a power plant. The dynamic information is, for example, a record that is acquired or updated within a predetermined time (for example, several [seconds] to several [hours]), and the static information is a record that is not acquired or updated within the predetermined time, but is acquired or updated at time intervals longer than the predetermined time. Each server device SV stores different types of information. Details of the information stored in the server devices SV will be described later.

The information providing device 100 acquires monitoring information desired by an operator when operating the power plant from the server device SV, and displays the acquired monitoring information on the first terminal device TM1 in the manner desired by the operator. The information providing device 100 also acquires monitoring information desired by a repair person when repairing the power plant from the server device SV, and displays the acquired monitoring information on the second terminal device TM2 in the manner desired by the repair person. Below, a case will be described in which the information providing device 100 provides a website including one or more web pages showing monitoring information according to the user (i.e., operates as a web server) to provide the monitoring information desired by the user in the manner desired by the user.

The monitoring information may be provided to the user as an application program is executed on the terminal device TM. In this case, the information providing device 100 instructs the application program or sets the application program to provide the monitoring information desired by the user in the manner desired by the user.

Each record in the database DB is an example of "monitoring information." The records in the log information database DB1 are an example of "dynamic information." The records in the facility management information database DB2, the records in the event information database DB3, and the records in the maintenance information database DB4 are examples of "static information."

Note that the records stored in each database DB are merely examples and are not limited to these. The records may contain some of the information described above, or may contain information other than the information described above.

[Regarding the information providing device 100]
FIG. 8 is a diagram showing an example of the configuration of the information providing device 100. The information providing device 100 includes, for example, a control unit 110, a communication unit 150, a display control unit 152, and a storage unit 160. The control unit 110 includes, for example, a template generating unit 120, a correspondence processing unit 130, and a maintenance operation unit 140. These components are realized by, for example, a processor such as a CPU (Central Processing Unit) executing a program (software) stored in the storage unit 160. In addition, some or all of these components may be realized by hardware (including circuitry) such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a GPU (Graphics Processing Unit), or may be realized by cooperation between software and hardware.

Based on the control of the control unit 110, the communication unit 150 communicates with the collection device 200, the anomaly detection device 300, each server device SV, the first terminal device TM1, and the second terminal device TM2 via the network NW to send and receive information.

The display control unit 152 causes the terminal device TM to display various images based on the control of the control unit 110.

The storage unit 160 may be realized by a storage device (a storage device with a non-transient storage medium) such as a HDD (Hard Disk Drive) or a flash memory, or may be realized by a removable storage medium (non-transient storage medium) such as a DVD or a CD-ROM, or may be a storage medium attached to a drive device. In addition, a part or all of the storage unit 160 may be an external device accessible by the information providing device 100, such as a NAS or an external storage server. In addition to programs, the storage unit 160 stores information such as layout information 161, template information 162, and context menu information 163. Details of each piece of information will be described later.

The template generation unit 120 generates template information 162 that indicates a standard format for displaying the monitoring information desired by the user on the terminal device TM.

The matching processing unit 130 performs processing to match various types of monitoring information to images related to the equipment being monitored, which are images used by operators when operating the power plant or by repair personnel when maintaining the power plant.

The maintenance operation unit 140 displays the monitoring information desired by the user on the terminal device TM in the display format desired by the user based on the template information 162 generated by the template generation unit 120. The maintenance operation unit 140 also performs processing related to the maintenance operation of the power plant in response to operations performed on the terminal device TM by an operator operating the power plant or by a repairman maintaining the power plant.

[Regarding the template generation unit 120]
9 is a functional configuration diagram of the template generation unit 120. The template generation unit 120 generates template information 162 for displaying monitoring information desired by a user on the terminal device TM. The template generation unit 120 includes, for example, a reception unit 121 and a template information generation unit 122. Details of each unit included in the template generation unit 120 will be described below.

The reception unit 121 receives, for example, an instruction from a user via the terminal device TM to select the monitoring information desired by the user from among the monitoring information stored in the server device SV, and an instruction to select the display format of the monitoring information desired by the user.

The template information generating unit 122 generates template information 162 based on the user's instructions received by the receiving unit 121.

[Deciding the layout]
The process of generating the template information 162 will be described in detail below. First, the reception unit 121 receives an instruction for the arrangement (layout) when the monitoring information is displayed on the terminal device TM based on the layout information 161. Fig. 10 is a diagram showing an example of a layout diagram LY included in the layout information 161. The layout information 161 includes the number of images showing the monitoring information, and one or more layout diagrams LY showing the layout of the images showing the monitoring information. In this embodiment, a case will be described where the layout information 161 includes three layout diagrams LY1 to LY3.

In FIG. 10, layout diagram LY1 includes an account image showing the user using the terminal device TM, a title image showing the title of the entire image (e.g., the user's associated plant or affiliation, etc.), and five images showing monitoring information. Layout diagram LY2 includes an account image, a title image, and three images showing monitoring information. Layout diagram LY3 includes an account image, a title image, and seven images showing monitoring information.

Figure 11 is a diagram showing an example of a selection image IMs1 used to select a layout diagram LY. The reception unit 121 displays the selection image IMs1 on the terminal device TM and receives the selection of the layout desired by the user as the display format of the monitoring information. In Figure 11, the selection image IMs1 is an image used to select the layout diagram LY of each page from the top page (i.e., page 1) to page 5 that constitutes the website that provides the monitoring information, and includes a message MS1 such as "Please select the layout for each page" that prompts the user to select a layout.

The website providing the monitoring information may be realized by more than five web pages, or may be realized by less than five web pages.

The reception unit 121 receives, as a user instruction, an operation input by the user to the terminal device TM in response to the display of the selection image IMs1. The template information generation unit 122 determines the layout of the images showing the monitoring information on the web page based on the user instruction received by the reception unit 121. In FIG. 11, the template information generation unit 122 determines the layout of page 1 as layout diagram LY1, the layout of page 2 as layout diagram LY2, and the layout of pages 3 to 5 as layout diagram LY2.

In addition to what is included in the layout information 161, the layout of the account image, title image, and image showing monitoring information may be determined by instructions from the user for the layout diagram LY. In this case, the reception unit 121 receives instructions for laying out the account image, title image, and image showing monitoring information based on operations input by the user to the terminal device TM, and generates the layout diagram LY based on the received instructions.

[Regarding monitoring information determination]
Next, the reception unit 121 receives a selection of monitoring information to be shown as an image in the layout diagram LY. Fig. 12 is a diagram showing an example of a selection image IMs2 used to select monitoring information. The reception unit 121 displays, on the terminal device TM, a selection image IMs2 for each page of a website that provides monitoring information, and receives a selection of monitoring information desired by the user. In Fig. 12, the selection image IMs2 includes options for selecting monitoring information that is the source data of five images included in the layout diagram LY1 of the top page selected in the selection image IMs1, and a message MS2 such as "Please select the data to be displayed on the top page" that prompts the user to select monitoring information.

The monitoring information options are, for example, "the latest record in the log information database DB1," "a record in the facility management information database DB2 relating to a specific target device," "a record in the event information database DB3 from the present to a specified time ago," "the latest record in the maintenance information database DB4," "a record in the spare parts information database DB5 relating to a specific target device," etc.

The reception unit 121 may include information derived using the monitoring information as an option for the monitoring information in addition to the monitoring information itself (i.e., the record itself in the database DB). In this case, the reception unit 121 displays a selection image IMs2 on the terminal device TM to which the information derived using the monitoring information is added as an option, and accepts the selection of the monitoring information desired by the user. The selection image IMs2 in FIG. 12 includes options for information derived using the monitoring information, such as "power generation status," "event occurrence history," "generator output trend," "power generation amount," and "fuel consumption." For the information derived using the monitoring information, the monitoring information used for derivation and the derivation method are determined in advance.

"Power generation status" is, for example, a ratio derived based on records in the log information database DB1 or records in the facility management information database DB2, and is information indicating the ratio of the current power generation amount to the power generation amount target for a specified period for each generator equipped in the power generation plant. "Event occurrence history" is, for example, information indicating a group of records in the event information database DB3 for a specified period from the present time, whose "importance" is a specified rank (for example, importance "B") or higher. "Generator output trend" is, for example, information deriving the amount of generated power based on records shown in the log information database DB1 and indicating the derived output power amount of the power generation plant for each specified time period (for example, every hour, every 30 minutes). "Power generation amount" is, for example, a value derived based on records in the log information database DB1, and is information indicating a value indicating the amount of power generation for a specified period for each generator equipped in the power generation plant. "Fuel consumption" is, for example, a value derived based on records in the log information database DB1, and is information indicating the ratio of fuel consumption to the amount of generated power for a specified period.

The reception unit 121 receives, as a user instruction, an operation input by the user to the terminal device TM in response to the display of the selection image IMs2. The template information generation unit 122 determines the monitoring information to be assigned to the layout diagram LY of each page based on the user instruction received by the reception unit 121. In FIG. 12, the template information generation unit 122 determines that, of the five images included in the layout of one page, the first image is assigned an image showing the power generation status, the second image is assigned an image showing the generator output trend, the third image is assigned an image showing the event occurrence history, the fourth image is assigned an image showing the amount of power generated, and the fifth image is assigned an image showing the amount of energy source consumption.

The reception unit 121 may refer to template information 162 related to other users and display on the terminal device TM a selection image IMs2 to which information that is frequently used by other users is added as an option for monitoring information. For example, the reception unit 121 acquires the user ID of the user from the terminal device TM, and searches the user information database DB6 using the acquired user ID as a search key to identify the affiliation of the user. The reception unit 121 identifies other users to whom an affiliation ID similar to the identified affiliation ID is associated. The reception unit 121 refers to the template information 162 of the identified other users and identifies options for monitoring information to be provided to the other users. The reception unit 121 displays on the terminal device TM a selection image IMs2 to which the options of the identified other users are added, and accepts the selection of monitoring information desired by the user.

[Determining the display format of monitoring information]
Next, the reception unit 121 receives a selection of the display mode of the selected monitoring information. Fig. 13 is a diagram showing an example of a selection image IMs3 used to select the display mode of the monitoring information. A selection image IMs3 for each page of a website providing monitoring information is displayed on the terminal device TM, and the selection of the display mode of the monitoring information desired by the user is received. In Fig. 13, the selection image IMs3 includes options for selecting the display mode of the monitoring information selected in the selection image IMs2 for each image, and a message MS3 such as "Please select the data display method" that prompts the user to select the display mode of the monitoring information.

The display mode options for the monitoring information are, for example, a "meter" that indicates part of the information included in the record, a "line graph" that indicates part of the information included in the record, a "number" that indicates part of the information included in the record, an "image" that indicates a record or part of the information included in the record, etc. Note that the display mode options for the monitoring information are only examples and are not limited to these, and other options may be included. In addition, the reception unit 121 may add the display mode options for the monitoring information based on the user's instruction via the terminal device TM, may refer to and add information that is frequently used by other users as the display mode options for the monitoring information, or may predetermine the display mode options according to the characteristics of the monitoring information. For example, when the monitoring information is a record in the log information database DB1, the reception unit 121 includes a graph as an option for the display mode of the numerical values of the measurement data and the like included in the record, and when the monitoring information is a record in the event information database DB3, includes a table format as an option for the display mode of the information related to the occurrence event.

The reception unit 121 receives, as a user instruction, an operation input by the user to the terminal device TM in response to the display of the selection image IMs3. The template information generation unit 122 determines the display mode of the selected monitoring information based on the user instruction received by the reception unit 121. In FIG. 13, the template information generation unit 122 determines that, of the five images included in the layout of one page, the first image displays the value or degree (level) included in the corresponding monitoring information in a meter format, the second image displays the value included in the corresponding monitoring information using a line graph, the third image displays an image showing the monitoring information (record), and the fourth and fifth images display the value or degree (level) included in the corresponding monitoring information using a bar graph.

[About determining the context menu]
Next, the reception unit 121 receives a selection of a context menu to be associated with the image. Fig. 14 is a diagram showing an example of a selection image IMs4 used for selecting a context menu. A selection image IMs4 for each page of a website that provides monitoring information is displayed on the terminal device TM, and the selection of a context menu to be associated with the monitoring information (image showing the monitoring information) is received.

The context menu is a menu that is displayed, for example, when an operation that causes the context menu to be displayed on an associated image (for example, by right-clicking the mouse) is performed. The context menu is used to provide more detailed information about the image (monitoring information) to which the context menu is associated, or to execute processing on the target device related to the monitoring information. When a context menu is selected while the context menu is being displayed by an operation that causes the context menu to be displayed, the maintenance operation unit 140, which will be described later, executes processing related to the selected context menu.

In FIG. 14, the selection image IMs4 includes, for each image represented by the display mode of the surveillance information determined in the selection image IMs3, an option to select a context menu to be associated with the image, and a message MS4 such as "Please select the context menu to be associated with each image" that prompts the user to select a context menu.

The options in the context menu are, for example, an "Event details" menu, a "Facility details" menu, and a "Repair request form issue" menu. Note that the options in the context menu are merely examples and are not limited to these, and other options may be included. Furthermore, the reception unit 121 may add options for the display mode of the monitoring information based on instructions from the user via the terminal device TM, or may add options for the display mode of the monitoring information by referring to information that is frequently used by other users.

The reception unit 121 receives, as a user instruction, an operation input by the user to the terminal device TM in response to the display of the selected image IMs4. The template information generation unit 122 determines a context menu to be associated with the image showing the monitoring information of each page based on the user instruction received by the reception unit 121. In FIG. 14, the template information generation unit 122 determines that three context menus, an "Event detailed information" menu, a "Facility detailed information" menu, and a "Repair request form issue" menu, are to be associated with each image showing the monitoring information (record) of the third image.

When a context menu is selected, the maintenance operation unit 140 (described later) displays the monitoring information corresponding to the context menu in a predetermined display format on the terminal device TM using a layout diagram LY corresponding to the selected context menu based on the context menu information 163. Details of the context menu information 163 will be described later.

FIG. 15 is a diagram showing an example of the contents of template information 162. Based on the above-mentioned determination, the template information generating unit 122 generates (updates) template information 162 including one or more records for each user in which information indicating the layout diagram LY of each page, monitoring information associated with the images included in the layout diagram LY, information indicating the display mode of the monitoring information, and information indicating a context menu associated with the images indicating the monitoring information are associated with each other, and stores the template information 162 in the storage unit 160. The template information 162 is an example of display information, and the template information generating unit 122 is an example of a "generating unit".

Figure 16 is a diagram showing an example of the contents of context menu information 163. Context menu information 163 is information that includes, for example, information indicating a layout drawing LY, monitoring information associated with an image included in the layout drawing LY, information indicating the display mode of the monitoring information, and a record for each context menu associated with an image indicating the monitoring information.

Note that, when a record of the template information 162 for a user of the terminal device TM already exists, the template generation unit 120 may not perform a process of generating a record of the template information 162 for the user. Specifically, the reception unit 121 receives a user ID related to the user who uses the terminal device TM. The template information generation unit 122 searches the template information 162 using the user ID received by the reception unit 121 as a search key, and determines whether or not a record of the template information 162 for the user exists. In addition, although the above description has been given of a case in which the template information 162 includes a record for each user, this is not limiting, and the template information 162 may include a record for each user's affiliation or each user's occupation. In this case, the template information generation unit 122 can reduce the effort of generating records when multiple users use the same template.

[Operation flow]
17 is a flowchart showing an example of a series of processing steps of the template generating unit 120. First, the receiving unit 121 causes the communication unit 150 to acquire information related to a user who uses the terminal device TM via the network NW (step S100). The information related to the user is, for example, the user's login information, and the login information includes, for example, a user ID and a user name. Next, the receiving unit 121 searches the template information 162 using the received user ID as a search key, and determines whether or not there is a record associated with the user ID (step S102). If the receiving unit 121 determines that there is a record associated with the user ID, it does not perform processing to generate a record in the template information 162, and ends the processing.

If the reception unit 121 determines that there is no record associated with the user ID, it causes the terminal device TM to display the selected images IMs1 to IMs4 (step S104). The reception unit 121 receives, as an instruction from the user, an operation input by the user to the terminal device TM in response to displaying the selected images IMs1 to IMs4 on the terminal device TM (step S106). The instruction from the user is, for example, an instruction to select a layout diagram LY of each page of the website providing the monitoring information, an instruction to select the monitoring information to be displayed as an image on the layout diagram LY, an instruction to select a display mode of the selected monitoring information, and an instruction to select a context menu to be associated with the image showing the monitoring information. The template information generation unit 122 generates a record of the template information 162 for each user based on the information received by the reception unit 121, and generates (updates) the template information 162 (step S108).

[Monitoring information related to the content desired by the user]
The template information generating unit 122 may determine other types of monitoring information than the monitoring information selected by the user as the monitoring information to be provided to the user. For example, when a record of a certain database DB is selected as the monitoring information to be displayed as an image in the selection image IMs2 (see FIG. 12 ), the template information generating unit 122 may select a record of a database DB of another type related to the selected monitoring information, which is different from the selected monitoring information, as the monitoring information to be displayed as an image. The template information generating unit 122 may determine other types of related monitoring information based on information indicating a predetermined related database DB, or may determine other types of monitoring information based on statistics of the selection results of the monitoring information to be displayed as an image by other users.

The template information generating unit 122 may also determine the monitoring information desired by the user without using the user's selection. For example, the template information generating unit 122 may determine the monitoring information to be provided to the user based on the user's affiliation or characteristics (e.g., job title). In general, uses with matching affiliations or characteristics may require similar monitoring information. Therefore, the template information generating unit 122 may generate a record of template information 162 for each user's affiliation or characteristics, and determine the monitoring information to be provided to the user.

[Regarding the Correlation Processing Unit 130]
18 is a functional configuration diagram of the association processing unit 130. The association processing unit 130 performs processing to associate various types of monitoring information with drawing data, and provides monitoring information related to the target device shown in the drawing data together with the drawing data. The association processing unit 130 includes an identifying unit 131, an acquiring unit 132, and an association unit 133. Details of each unit included in the association processing unit 130 will be described below.

The identification unit 131 identifies the range of the target device shown by the image for each piece of drawing data stored in the equipment management information database DB2. For example, when the drawing data stored in the equipment management information database DB2 is drawing data such as CAD (Computer-Aided Design), the identification unit 131 identifies the component that represents the target device. Identifying the component that represents the target device is an example of identifying the position and range in the drawing data where the target device is shown. The component is associated with basic information of the target device (for example, the name of the target device, the target device ID, etc.). Furthermore, when the drawing data stored in the equipment management information database DB2 is image data (hereinafter, a drawing image), the identification unit 131 identifies the range that represents the target device. The range that represents the target device is, for example, the range of pixels that constitute the drawing symbol, the range of pixels that constitute the shape of the target device, the range of pixels that indicate the name of the target device, the range of pixels that indicate the target device ID, etc., among the pixels that constitute the drawing image.

The acquisition unit 132 acquires monitoring information related to the target devices indicated in the range identified by the identification unit 131 from each database DB. The acquisition unit 132 searches each database DB using the target device ID identified by the identification unit 131 as a search key, and acquires monitoring information related to the target devices indicated in the drawing data. Hereinafter, it is assumed that the acquisition unit 132 acquires a reference destination of the monitoring information (for example, a storage location of the monitoring information stored in the database DB) as the monitoring information, rather than the monitoring information itself.

The association unit 133 associates predetermined monitoring information among the monitoring information acquired by the acquisition unit 132 as monitoring information to be provided as a context menu corresponding to the range identified by the identification unit 131. The monitoring information of the context menu associated with the range identified by the identification unit 131 may be selected by the user by a process similar to the above-mentioned process, or may be predetermined. Hereinafter, a case will be described in which the association unit 133 provides predetermined monitoring information as a context menu of drawing data regardless of the user's selection. The predetermined monitoring information is, for example, "system diagram data", "wire diagram data", "wiring diagram data", and "image data" among the monitoring information acquired by the acquisition unit 132. When the record of the template information 162 includes "system diagram data", "wire diagram data", "wiring diagram data", etc. as monitoring information, the template information generation unit 122 generates a record by associating the monitoring information associated by the association unit 133 (in this case, "system diagram data", "wire diagram data", "wiring diagram data", and "image data") as a context menu.

[Operation flow]
19 is a flowchart showing an example of a series of operations of the association processing unit 130. First, the identification unit 131 identifies a range representing the target equipment shown by the image for each drawing data stored in the equipment management information database DB2 (step S200). The acquisition unit 132 identifies the target equipment ID represented in the range identified by the identification unit 131 (step S202). The acquisition unit 132 searches each database DB using the identified target equipment ID as a search key, and acquires monitoring information related to the target equipment represented in the range identified by the identification unit 131 (step S204). The association unit 133 associates a predetermined piece of monitoring information acquired by the acquisition unit 132 as monitoring information to be provided as a context menu corresponding to the range identified by the identification unit 131 (step S206).

[Regarding the Maintenance and Operation Department 140]
20 is a functional configuration diagram of the maintenance operation unit 140. The maintenance operation unit 140 displays the monitoring information desired by the user on the terminal device TM in the display mode desired by the user based on the template generated by the template generation unit 120. The maintenance operation unit 140 includes, for example, an acquisition unit 141, an image generation unit 142, a display control unit 152, a reception unit 143, an update unit 145, and a determination unit 144. Details of each unit included in the maintenance operation unit 140 will be described below.

The acquisition unit 141 identifies a record corresponding to a user who uses the terminal device TM based on the template information 162, and acquires the monitoring information contained in the identified record from each database DB. For example, in response to acquiring information (e.g., login information) indicating that use of the information providing system 1 has begun, the acquisition unit 141 starts acquiring the monitoring information corresponding to the user.

The image generation unit 142 generates information for displaying an image of the content desired by the user on the terminal device TM based on the monitoring information acquired by the acquisition unit 141. The display control unit 152 causes the terminal device TM to display an image based on the information generated by the image generation unit 142. The display control unit 152 also causes the terminal device TM to display various images in response to instructions from the user received via the terminal device TM by the reception unit 143 described below. Furthermore, when the update unit 145 described below determines that there is an abnormality in the power plant, the display control unit 152 causes the terminal device TM to display an image desired by the user in response to the abnormality.

Note that "the image generation unit 142 generating information for displaying an image of the content desired by the user on the terminal device TM" includes the image generation unit 142 determining the position of the image showing the monitoring information in the layout drawing LY based on the template information 162, associating each image of the layout drawing LY with the monitoring information (associating each image of the layout drawing LY with a storage location stored as a link in the database DB), and generating configuration information of a web page that provides the monitoring information, and the image generation unit 142 generating the image itself to be displayed on the terminal device TM based on the monitoring information acquired by the acquisition unit 141.

In the former case, the image generation unit 142 does not generate an image, the acquisition unit 141 acquires a reference of the monitoring information (e.g., a storage location of the monitoring information stored in the database DB) as the monitoring information, rather than the monitoring information itself, and the display control unit 152 provides the information generated by the image generation unit 142 (in this case, configuration information of a web page) to the terminal device TM. In the latter case, the image generation unit 142 generates an image, the acquisition unit 141 acquires the monitoring information itself from the database DB, and the display control unit 152 provides the image generated by the image generation unit 142 to the terminal device TM.

The following describes the case where the acquisition unit 141 acquires a reference for the monitoring information, rather than the monitoring information itself, and the image generation unit 142 does not generate an image, but instead determines the position of the image showing the monitoring information in the layout drawing LY based on the template information 162, and associates each image in the layout drawing LY with the monitoring information, thereby generating configuration information for a web page that provides the monitoring information, and the display control unit 152 provides the information generated by the image generation unit 142 to the terminal device TM (i.e., the former case).

The reception unit 143 receives operations input by the user to the terminal device TM in response to an image being displayed on the terminal device TM based on the information generated by the image generation unit 142.

The determination unit 144 determines whether or not an abnormality in the power plant has been detected by the abnormality detection device 300.

The update unit 145 updates the information in each database DB based on the operations accepted by the acceptance unit 143.

[During maintenance operations]
The following describes the display of images displayed on the first terminal device TM1 and the second terminal device TM2 during maintenance operation.

[Top page of the first terminal device TM1]
First, the acquisition unit 141 acquires the login information of the operator from the first terminal device TM1. The acquisition unit 141 searches the template information 162 using the user ID of the operator included in the acquired login information as a search key. The acquisition unit 141 searches the template information 162 and identifies a record to which the user ID of the operator of the first terminal device TM1 is associated. The acquisition unit 141 identifies a layout diagram LY of a top page included in the identified record and monitoring information shown as an image included in the layout diagram LY, and causes the communication unit 150 to acquire the identified monitoring information from each database DB via the network NW.

The image generating unit 142 generates information for displaying an image on the first terminal device TM1 based on the monitoring information acquired by the acquiring unit 141 and the records of the template information 162. The information for displaying an image on the first terminal device TM1 generated by the image generating unit 142 is an example of "first display information."

FIG. 21 is a diagram showing an example of a top page image IMtp1 displayed on the first terminal device TM1. The image generating unit 142 generates information for displaying the top page image IMtp1 of the website providing monitoring information as an image desired by the operator using the first terminal device TM1, for example, based on the record of the template information 162. The top page image IMtp1 shown in FIG. 21 is composed of an account image IMa, a title image IMp, and a layout of a layout diagram LY1 including the first image IMt1 to the fifth image IMt5 showing the monitoring information. The first image IMt1 shows the monitoring information of the "power generation status" in the display mode of a "meter". The second image IMt2 shows the monitoring information of the "generator output trend" in the display mode of a "line graph". The third image IMt3 shows the monitoring information of the "event occurrence history" in the display mode of a "numerical value". The fourth image IMt4 shows the monitoring information of the "power generation amount" in the display mode of a "bar graph". The fifth image IMt5 shows the monitoring information for "fuel consumption" in the form of a "bar graph."

21, a context menu is associated with the third image IMt3. When the receiving unit 143 receives an operation for displaying a context menu for the third image IMt3 (for example, right-clicking a record shown in the third image IMt3 with a cursor linked to a mouse), the image generating unit 142 identifies the context menu associated with the third image IMt3 based on the template information 162 and generates information for displaying a context menu image IMc showing the identified context menu. In this case, the context menu associated with the third image IMt3 is the "Event details/Facility details/Repair request form issue" menu, and these menus are shown in the context menu image IMc. The display control unit 152 displays the context menu image IMc on the terminal device TM based on the information generated by the image generating unit 142. Details of the images to be displayed when each menu shown in the context menu image IMc is operated will be described later.

Links Lk2 to Lk5 to other pages (pages 2 to 5) of the website are shown at the bottom of the account image IMa, and when the reception unit 143 receives an operation on these links, it generates each page image based on the template information 162 corresponding to the operated page. The process of generating each page image is similar to the process of generating the top page described above, so a description thereof will be omitted.

[Top page of the second terminal device TM2]
First, the acquisition unit 141 acquires the login information of the repairman from the second terminal device TM2. The acquisition unit 141 searches the template information 162 using the user ID of the repairman included in the acquired login information as a search key. The acquisition unit 141 searches the template information 162 and identifies a record to which the user ID of the repairman of the second terminal device TM2 is associated. The acquisition unit 141 identifies the layout diagram LY of the top page included in the identified record and monitoring information shown as an image included in the layout diagram LY, and causes the communication unit 150 to acquire the identified monitoring information from each database DB via the network NW.

The image generating unit 142 generates information for displaying an image on the second terminal device TM2 based on the monitoring information acquired by the acquiring unit 141 and the records of the template information 162. The information for displaying an image on the second terminal device TM2 generated by the image generating unit 142 is an example of "second display information."

Figure 22 is a diagram showing an example of a top page image IMtp2 displayed on the second terminal device TM2. The image generation unit 142 generates information for displaying a top page image IMtp2 of a website providing monitoring information as an image desired by a repairman using the second terminal device TM2, for example, based on a record of the template information 162. The top page image IMtp2 shown in Figure 22 is composed of an account image IMa, a title image IMp, and a layout of a layout diagram LY3 including a first image IMt1 to a seventh image IMt7 showing monitoring information.

The first image IMt1 shows a record (monitoring information) related to a preselected target device among the records of the equipment management information database DB2 in the display mode of "text". The second image IMt2 shows a prespecified (e.g., the latest) record among the records of the event information database DB3 in the display mode of "text". The third image IMt3 shows a prespecified (e.g., the latest) record for a preselected target device among the records of the maintenance information database DB4 in the display mode of "text". The fourth image IMt4 shows schedule information for a prespecified period (e.g., the last month) included in the monitoring information, which is a record of a repairman using the second terminal device TM2 among the records of the user information database DB6, in the display mode of "text". The fifth image IMt5 shows a record related to a preselected target device among the records of the spare parts information database DB5 in the display mode of "text". The sixth image IMt6 is procedure manual data included in the monitoring information, which is a record related to a pre-selected target device among the records in the equipment management information database DB2, and shows pre-specified (e.g., the latest) procedure manual data as an "image", and the seventh image IMt7 shows drawing data such as system diagram data, wiring diagram data, and layout diagram data included in the monitoring information, which is a record related to a pre-selected target device among the records in the equipment management information database DB2, as an "image".

Indicating the display mode of "text" includes the image generation unit 142 generating configuration information of a web page so as to display "text." Indicating the display mode of "image" includes the image generation unit 142 generating configuration information of a web page in which the original data has been processed (enlarged, reduced, rotated, trimmed, etc.) so as to be easily displayed on the terminal device TM.

By the above-mentioned processing, the information providing device 100 can allow the operator to refer to images such as the top page image IMtp1 displayed on the first terminal device TM1, and can use them to help operate the power plant. In addition, the information providing device 100 can allow the repair personnel to refer to images such as the top page image IMtp2 displayed on the second terminal device TM2, and can use them to help repair the power plant.

[About the context menu]
Furthermore, the accepting unit 143 accepts, as an instruction from the user, an operation to select a context menu input by the user to the terminal device TM in response to the display control unit 152 displaying images of web pages such as top page images IMtp1-IMtp2 on the terminal device TM based on the information generated by the image generating unit 142. The image generating unit 142 generates information for displaying a context menu image IMc based on the monitoring information corresponding to the selected image and the selected context menu. The display control unit 152 displays the context menu image IMc on the terminal device TM based on the information generated by the image generating unit 142.

[Event details]
When the accepting unit 143 accepts an operation to select the "event detail information" menu while the context menu image IMc is being displayed, the image generating unit 142 identifies the monitoring information in which the operation to select the context menu was performed, and generates information for displaying the execution screen IMe1 based on the identified monitoring information. Hereinafter, a case will be described in which the operation to select the context menu was performed in the third image IMt3 (a record with "event occurrence history") of the top page image IMtp1 displayed on the first terminal device TM1.

Figure 23 is a diagram showing an example of an execution screen IMe1 of the "Event detailed information" menu displayed on the terminal device TM. The image generation unit 142 identifies a record in which an operation to select a context menu was performed among the records of the "Event occurrence history" shown in the third image IMt3, and generates information for displaying the execution screen IMe1 related to the identified record.

The execution screen IMe1 shown in FIG. 23 is composed of an account image IMa, a title image IMp, and a layout diagram LY2 including a first image IMt1 to a third image IMt3 showing monitoring information. The first image IMt1 shows a record corresponding to a specified record in the event information database DB3 in a "text" display mode. The second image IMt2 shows records in the log information database DB1 from the date and time included in the specified record up to a predetermined period (e.g., several [hours] to several [days]) ago in a "line graph" display mode. The third image IMt3 shows the state transition of a record from the date and time included in the specified record in the log information database DB1 to the current time in a graph display mode.

By performing the above-described process, the information providing device 100 allows the user to refer to the execution screen IMe1 displayed on the terminal device TM and to understand in more detail the event that has occurred on the target device.

[Facility details information]
When the receiving unit 143 receives an operation to select the "facility details information" menu while the context menu image IMc is being displayed, the image generating unit 142 identifies the monitoring information in which the operation to select the context menu was performed, and generates information for displaying the execution screen IMe2 based on the identified monitoring information.

Figure 24 is a diagram showing an example of the execution screen IMe2 of the "Facility details information" menu displayed on the terminal device TM. The image generation unit 142 identifies a record in which an operation to select a context menu was performed among the records of the "Event occurrence history" shown in the third image IMt3, and generates information for displaying the execution screen IMe2 related to the identified record.

The execution screen IMe2 shown in FIG. 24 is composed of an account image IMa, a title image IMp, and a layout diagram LY2 including a first image IMt1 to a third image IMt3 showing monitoring information. The first image IMt1 shows, in a "text" display mode, a record associated with the target device ID included in the identified record among the records in the facility management information database DB2. The second image IMt2 shows, in a graph display mode, the state transition of the record from the date and time included in the identified record to a predetermined period (e.g., several [hours] to several [days]) ago, for the records in the log information database DB1 associated with the same target device ID as the identified record. The third image IMt3 shows, in an "image", drawing data such as system diagram data, wiring diagram data, and layout diagram data included in the record associated with the target device ID included in the identified record among the records in the log information database DB1.

The third image IMt3 may show one or two of the system diagram data, wiring diagram data, and layout diagram data. The image showing each piece of drawing data may further be associated with a context menu that displays the drawing data in an easily viewable manner for the user (e.g., enlarged). In this case, when the receiving unit 143 receives an operation to select the context menu of these images, the image generating unit 142 generates information for displaying the drawing data in an easily viewable manner for the user.

25 is a diagram showing an example of an execution screen IMe3 of a context menu associated with drawing data. For example, when an operation to display a context menu is received by the reception unit 143 for the system diagram data, wiring diagram data, and layout diagram data shown in the third image IMt3 included in the execution screen IMe2 of FIG. 24, the display control unit 152 displays the execution screen IMe3. The execution screen IMe3 shown in FIG. 25 is configured by a layout including an account image IMa, a title image IMp, and a first image IMt1 showing monitoring information. The first image IMt1 is a drawing image showing the drawing data for which an operation to display a context menu has been performed among the system diagram data, wiring diagram data, and layout diagram data. Below, a case where the first image IMt1 of the execution screen IMe3 is a drawing image showing system diagram data will be described.

The image generating unit 142 determines whether an operation to display a context menu associated with a range representing a target device in the system diagram data of the first image IMt1 has been accepted by the accepting unit 143. When an operation has been accepted by the accepting unit 143, the image generating unit 142 generates information for displaying a context menu image IMc. At this time, the context menu shown in the context menu image IMc is a context menu that provides the monitoring information associated by the associating unit 133. In this case, the context menu shown in the context menu image IMc is a context menu that provides "wiring diagram data", "wiring diagram data", and "image data".

In response to the display control unit 152 causing the terminal device TM to display the execution screen IMe3 including the context menu image IMc based on the information generated by the image generation unit 142, the reception unit 143 receives, as a user instruction, an operation to select a context menu input by the user to the terminal device TM. The image generation unit 142 executes the context menu based on the monitoring information corresponding to the selected image and the selected context menu. Below, a case will be described in which, in the context menu image IMc, an operation to display "wiring diagram data" is performed as monitoring information related to the target device represented in the range in which the operation to display the context menu is performed. The image generation unit 142 generates information for displaying the execution screen IMe3 including a drawing image of the wiring diagram data.

The display control unit 152 causes the terminal device TM to display an execution screen IMe3 including a drawing image showing the system diagram data and a drawing image of the wiring diagram data based on the information generated by the image generation unit 142. At this time, the display control unit 152 may display the execution screen IMe3 so that the drawing image of the wiring diagram data is displayed in a position that does not overlap with the drawing image of the system diagram data already included in the execution screen IMe3. The display control unit 152 may also display the execution screen IMe3 so that only the drawing image of the wiring diagram data is displayed on the execution screen IMe3 (i.e., without including the drawing image of the wiring diagram data).

Furthermore, through the above-described processing, the information providing device 100 can allow the user to refer to the execution screen IMe2 displayed on the terminal device TM, allowing the user to understand the target device in more detail. Furthermore, the information providing device 100 can allow the user to refer to the drawing data using the execution screen IMe3, making it easier for the user to refer to related information related to the target device.

[Regarding the issuance of repair request forms]
When the receiving unit 143 receives an operation to select the "Repair request form issue" menu while the context menu image IMc is being displayed, the image generating unit 142 identifies the monitoring information in which the operation to select the context menu was performed, and generates information for displaying the execution screen IMe3 based on the identified monitoring information.

Figure 26 is a diagram showing an example of an execution screen IMe4 of the "Facility Details" menu displayed on the terminal device TM. The image generation unit 142 identifies a record in which an operation to select a context menu was performed among the records of the "Event Occurrence History" shown in the third image IMt3, and generates information for displaying the execution screen IMe3 related to the identified record.

The execution screen IMe4 shown in FIG. 26 is composed of an account image IMa, a title image IMp, and a layout of a layout diagram LY3 including a first image IMt1 to a seventh image IMt7 showing monitoring information. The first image IMt1 shows a record in the equipment management information database DB2 to which the target device ID included in the specified record is associated in a display mode of "text". The second image IMt2 shows a record in the event information database DB3 corresponding to the specified record in a display mode of "text". The third image IMt3 shows a latest record in the maintenance information database DB4 to which the target device ID included in the specified record is associated in a display mode of "text". The fourth image IMt4 shows records in the log information database DB1 to which the same target device ID as the specified record is associated, from the date and time included in the specified record until a predetermined period (for example, several [hours] to several [days]) ago, in a display mode of "line graph". The fifth image IMt5 shows, in a "text" display mode, the latest record in the spare parts information database DB5 that is associated with the same target equipment ID as the identified record. The seventh image IMt7 shows, in a "image" display mode, a record in the user information database DB6 in which the power plant in which the target equipment related to the identified record is installed is associated as the power plant in which the user works, showing the user related to the record. The sixth image IMt6 shows the "Issue repair request form" button BT1 with which a context menu is associated. The context menu associated with the button BT1 is, for example, a menu for issuing a repair request form.

When the instruction to issue a repair request form by selecting button BT1 is received by the reception unit 143, the maintenance operation unit 140 executes a process to issue a repair request form for the target device related to the identified record. First, the display control unit 152 displays an image to be used when issuing the repair request form on the terminal device TM. The image to be used when issuing the repair request form is, for example, an image that prompts the input or selection of information required for issuing the repair request form. Next, the reception unit 143 receives an operation input by the user to the terminal device TM in response to the display of the image to be used when issuing the repair request form as a user instruction. The operation input by the user to the terminal device TM is, for example, an operation to specify the issue destination of the repair request form (for example, a user working at a power generation plant where the target device to be repaired is installed), an operation to specify the repair date and time, an operation to specify the repair content, etc.

Based on the information received by the reception unit 143, the image generation unit 142 generates information for displaying an image showing the repair request form (hereinafter, the repair request form image) on the terminal device TM to which the repair request form is to be issued. The repair request form image is an image showing, for example, the ID of the target device to be repaired, information showing the target device to be repaired, records of the target device to be repaired for a pre-specified period (e.g., the most recent month) among the records of the log information database DB1, records of the target device to be repaired among the records of the spare parts information database DB5, records of the target device to be repaired among the records of the equipment management information database DB2, etc. Based on the information generated by the image generation unit 142, the display control unit 152 causes the image to be displayed on the terminal device TM used by the user to which the repair request form is to be issued. The user of the terminal device TM on which the image showing the repair request form is displayed repairs the target device to be repaired based on the contents shown in the repair request form.

In addition, the reception unit 143 may not accept an instruction to issue a repair request form for the user to whom the repair request form is issued in a predetermined case. The predetermined case is, for example, when an operation to specify a repair date and time is accepted in a state in which an image used to issue a repair request form is displayed, and the user who issued the repair request form is unable to perform repairs for the user to whom the repair request form is issued at the repair date and time specified by the user (e.g., other plans are scheduled). The reception unit 143, for example, refers to schedule information of the user to whom the repair request form is issued and determines whether or not to accept an instruction to issue a repair request form. If the reception unit 143 does not accept an instruction, the image generation unit 142 generates information for displaying an image including a prohibition message such as "The user requesting repairs cannot perform repairs at this repair date and time". The display control unit 152 may display an image used to issue a repair request form including a prohibition message (hereinafter, an image for issuing a repair request form) on the terminal device TM based on the information generated by the image generation unit 142.

The image generating unit 142 may generate information for displaying an image for issuing a repair request form, including user information of the user who can handle the repair, the date and time when the repair can be performed, etc., and the receiving unit 143 may receive this information before issuing the repair request. In this case, the image generating unit 142 generates an image used when obtaining the reason for repair from the user before displaying the image for issuing a repair request form on the terminal device TM. The receiving unit 143 receives information such as the scheduled date and time of repair and the scheduled period related to the repair, based on the operation input in response to the display control unit 152 displaying this information on the terminal device TM. As a result, the image generating unit 142 can generate information for displaying an image for issuing a repair request form, including user information of the user who can handle the repair, the date and time when the repair can be performed, etc., based on the information received by the receiving unit 143.

By the above-mentioned process, the information providing device 100 can have the user refer to the execution screen IMe4 displayed on the terminal device TM, and can have the user request repairs for the target device for which the context menu was operated from another user (e.g., a repairman) who works on the target device.

The maintenance operation unit 140 may also perform processing to issue a repair request form when an abnormality in the power plant is detected by the abnormality detection device 300. In this case, the determination unit 144 determines whether or not the information received from the abnormality detection device 300 by the communication unit 150 indicates that an abnormality has been detected in the power plant. When the determination result of the determination unit 144 indicates that an abnormality has been detected in the power plant, the maintenance operation unit 140 executes processing to issue a repair request form.

By the above-mentioned process, the information providing device 100 can allow the user to refer to the execution screen IMe4 displayed on the terminal device TM when an abnormality in the power plant is detected by the abnormality detection device 300, and can have the user request repairs for the target device for which the context menu was operated from another user (e.g., a repairman) who performs work related to the target device.

[Regarding repair result registration (update)]
Furthermore, the repairman to whom the repair request form is issued may register (update) the repair results of the target device in each database DB. In this case, the image generating unit 142 generates information for generating an image used when acquiring various information related to the repair. Then, the display control unit 152 causes the terminal device TM to display the image used when acquiring various information related to the repair based on the information generated by the image generating unit 142. Furthermore, the receiving unit 143 receives an operation input by the user to the terminal device TM as an instruction from the user in response to the display control unit 152 causing the terminal device TM to display the image. The update unit 145 updates each database DB based on the information accepted by the accepting unit 143. Details of the processing of each unit are described below.

First, the image generating unit 142 generates information for displaying an image prompting the repairman who is registering (updating) the repair results to input the target device ID of the repaired target device on the second terminal device TM2. The image prompting the input of the target device ID is, for example, an image including a comment box for inputting the target device ID on the first terminal device TM1 and a message such as "Please enter the repaired target device ID." In response to the image being displayed on the second terminal device TM2, the receiving unit 143 receives the target device ID of the target device repaired by the repairman based on the operation input by the repairman on the second terminal device TM2. The image generating unit 142 searches the database DB to be updated (e.g., the equipment management information database DB2, the spare parts information database DB5, etc.) using the target device ID received by the receiving unit 143 as a search key, and identifies the record related to the repaired target device.

The image generating unit 142 generates information for displaying an image that prompts the user to update the specified record. For example, when the target device is replaced, the image that prompts the user to update the specified record is an image that includes a comment box that accepts information about the target device after repair, such as the installation start date and fixed asset value, included in the record of the facility management information database DB2, and a message such as "Please enter the changed information about the target device after repair, such as the installation start date and fixed asset value." Also, for example, when spare parts are used to repair the target device, the image that prompts the user to update the specified record is an image that includes a comment box that accepts information about the number of spare parts for the repaired target device, included in the record of the spare parts information database DB5, and a message such as "Please enter the changed information about the spare parts."

The reception unit 143 receives the operation input by the repairman to the second terminal device TM2 as an instruction to specify various information in response to the display control unit 152 causing the first terminal device TM1 to display an image based on the information generated by the image generation unit 142. The update unit 145 updates each record based on the instruction received by the reception unit 143 and stores it in the corresponding database DB.

The image generating unit 142 also generates information for displaying an image that prompts the user to add a new record. Examples of images that prompt the user to add a new record include an image that prompts the user to add a record to the facility management information database DB2 when a new target device is added, an image that prompts the user to add a record to the maintenance information database DB4 regarding an abnormal event of a power plant that has been repaired, and an image that prompts the user to add a record to the spare parts information database DB5 when a repair is performed using spare parts.

The reception unit 143 receives the operation input by the repairman to the second terminal device TM2 as an instruction to specify various information in response to the display control unit 152 causing the first terminal device TM1 to display an image prompting the user to add a new record based on the information generated by the image generation unit 142. The update unit 145 generates each record based on the instruction received by the reception unit 143 and stores (registers) it in the corresponding database DB.

By performing the above-described process, the information providing device 100 can allow users to refer to the latest information from the database DB.

[Maintenance operation sequence]
27 is a sequence diagram showing an example of a series of operations related to the maintenance operation of the information providing system 1. First, the acquisition unit 141 acquires the user ID of the user who uses the terminal device TM (step S300). The image generation unit 142 uses the user ID acquired by the acquisition unit 141 as a search key to identify the user's record among the records of the template information 162 (step S302). The acquisition unit 141 acquires monitoring information indicated in the identified record from each database DB (step S304). The image generation unit 142 generates information for displaying the top page image IMtp on the terminal device TM based on the monitoring information acquired by the acquisition unit 141 (step S306). The display control unit 152 displays an image on the terminal device TM based on the information generated by the image generation unit 142 (step S308).

The reception unit 143 receives an operation input by the user to the terminal device TM in response to the image being displayed on the terminal device TM (step S310). The acquisition unit 141 determines whether the operation received by the reception unit 143 is an operation to issue a repair request form (step S312). If the acquisition unit 141 determines that the received operation is an operation to issue a repair request form, the process proceeds to step S328. The acquisition unit 141 identifies a record of the context menu information 163 corresponding to the screen to be displayed in response to the operation based on the operation received by the reception unit 143 (an operation to select a link Lk of another page, an operation to select a context menu, etc.), and acquires monitoring information indicated in the identified record from each DB (step S314). The image generation unit 142 generates information for displaying an image corresponding to the operation on the terminal device TM based on the monitoring information acquired by the acquisition unit 141 (step S316). The display control unit 152 causes the terminal device TM to display an image based on the information generated by the image generation unit 142 (step S318).

The abnormality detection device 300 detects an abnormality or a sign of an abnormality in the power plant being monitored (step S320). The abnormality detection device 300 determines whether an abnormality or a sign of an abnormality in the power plant being monitored has been detected (step S322). The abnormality detection device 300 repeats the process of step S320 until it determines that an abnormality or a sign of an abnormality in the power plant being monitored has been detected. If the abnormality detection device 300 determines that an abnormality in the power plant being monitored has been detected, it transmits information indicating that an abnormality has been detected to the information providing device 100 via the network NW (step S324).

The acquisition unit 141 determines whether or not information indicating that an abnormality has been detected in the power plant being monitored has been acquired from the abnormality detection device 300 (step S326). The information providing device 100 repeats the processes from steps S310 to S216 until the abnormality detection device 300 detects an abnormality or a sign of an abnormality in the power plant in the monitoring information.

When the acquisition unit 141 determines that information indicating that an abnormality has been detected in the power plant being monitored has been acquired from the abnormality detection device 300, the acquisition unit 141 acquires monitoring information used to generate information from each database DB in order to generate information for displaying an image for issuing a repair request form on the terminal device TM (step S328). The monitoring information used to generate information is, for example, monitoring information related to the target device for which repair has been requested. The image generation unit 142 generates information for displaying an image for issuing a repair request form on the terminal device TM based on the monitoring information acquired by the acquisition unit 141 (step S330). The display control unit 152 displays the image for issuing a repair request form on the terminal device TM (in this example, the first terminal device TM1) to which the repair request form is to be issued based on the information generated by the image generation unit 142 (step S332).

Based on the image for issuing the repair request form displayed on the screen, the first terminal device TM1 receives an operation performed by the operator on the first terminal device TM1 to specify the destination of the repair request form (for example, a user working at a power plant where the equipment to be repaired is installed) and an operation to specify the repair content (step S334). In response to the display control unit 152 displaying the image on the terminal device TM, the reception unit 143 receives the operation input by the operator to the first terminal device TM1 as the operator's instruction (step S336). Based on the operator's instruction received by the reception unit 143, the image generation unit 142 generates information for displaying the repair request form image on the terminal device TM to which the repair request form is issued (step S338). Based on the information generated by the image generation unit 142, the display control unit 152 displays the repair request form image on the terminal device TM used by the destination user (step S340).

[Operation flow]
28 is a flow chart showing an example of a series of operations of the database DB update process. First, the display control unit 152 displays an image prompting the repairman who performed the repair to update the record in the database DB or register a new record on the second terminal device TM2 (step S300). Next, the reception unit 143 receives an operation input by the repairman to the second terminal device TM2 in response to the image prompting the repairman to update or register the record being displayed on the second terminal device TM2 (step S302). The update unit 145 updates the record in the database DB or registers a new record in the database DB based on the information received by the reception unit 143 (step S304).
