Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant maintenance management system for automatically transmitting and receiving abnormal data of plant equipment in a plant maintenance management system using a network, identifying an abnormal location from the abnormal data, and displaying the corresponding screen on a screen. Regarding management device.

[0002]

2. Description of the Related Art Conventionally, there are many plant maintenance management apparatuses for transmitting abnormality of plant equipment to a receiving apparatus at a remote place. Currently, the most frequently used plant maintenance equipment is the local area network on the plant site.
(Hereinafter referred to as LAN) is installed, and the console for displaying the controller and plant equipment monitoring screen is LAN
It is a form of connecting with. The abnormality detected by the controller is transmitted via the LAN to the control server also connected to the LAN. The server sends abnormal data to the console and displays an alarm on the plant equipment monitoring screen on the console. In such a conventional technique, first, the information of the plant equipment monitoring screen displayed on the screen of the console is not a drawing created at the time of plant design, but is created in advance for target plant monitoring by simplifying the plant as much as possible. It is that it is an image image. Therefore, although it is possible to roughly specify the abnormal part, it takes time to specify which part of the actual equipment is abnormal. In fact, even if an anomaly is displayed on the console screen, at that point, only emergency measures can be taken for the anomaly, and humans have to spend time investigating the plant drawings for the root cause investigation. . Next, in order to place importance on the communication speed, the controller and the console for displaying the abnormal portion are connected by LAN. However, it does not use a global network such as the Internet. Further, recently, a plant maintenance management device using the Internet has been proposed. In the maintenance device using the Internet, a Web server other than the control server is arranged on the plant side. A general method is to convert the plant abnormality data transmitted from the controller into a data format that can be recognized and displayed by the receiving device by the Web server and transmit the data to the network. For example, in a system in which a receiving device receives abnormal data by a web browser, it is necessary for the web server to convert the transmission data into a file format (HTML, etc.) that can be displayed by the web browser and transmit the data. In addition, if more detailed visual information is to be transmitted, it is necessary to link it with a large amount of image data for transmission. Therefore, in this conventional technology, in order to convert the abnormal data to be transmitted and to send a large amount of image data,
There is a problem that high speed communication is not possible. Other conventional techniques include a remote maintenance method described in JP-A-10-177196 and JP-A-7-3206.
There is a remote maintenance device described in JP-A No. 22-22, a monitoring control system described in JP-A-10-371131, and a storage medium in which the program thereof is recorded.

[0003]

As described above, in the conventional plant maintenance management apparatus, although a rough plant abnormality location can be confirmed on the console, it is very difficult to identify the abnormality location at the equipment level. In addition, as a countermeasure when an abnormality occurs, generally, the equipment that caused the abnormality is identified from the abnormality data, and the fundamental abnormality location is identified from the corresponding drawing or log information output by the controller. However, performing such an analysis manually requires skilled knowledge and skill and a large amount of time, so that it is difficult for a professional plant monitor or a plant designer to easily identify the abnormal portion. Also, the plant designer
It is not always standing by at the plant installation site, and it is very difficult to quickly identify an abnormal place in the plant from a remote location and take countermeasures.

An object of the present invention is to transmit abnormal data at high speed in a plant maintenance management system for monitoring the operating status of a plant even when a global network is used, and identify the abnormal location of the plant at the drawing (device) level. ,
It is to display and enable quick response to plant abnormalities.

[0005]

[Means for Solving the Problem] In order to solve the above problems, when an abnormality occurs in a plant, means for storing the abnormality data of the equipment acquired from the controller in the database, and the server for the abnormal data Means to add header information that summarizes abnormal equipment information and protocol information according to the receiving device or network, and determine the format to be displayed on the screen and the abnormal place of the equipment from the header information of the abnormal data received by the receiving device Means and means for searching the drawing database for the corresponding abnormal portion and displaying the corresponding drawing and the abnormal portion on the drawing with an alarm.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the most basic system configuration which is an embodiment of the plant maintenance management apparatus of the present invention. In FIG. 1, the plant maintenance management device includes a controller 30 and a controller 30 that are connected to each other to give a control signal to a sensor 10 and an actuator 20 attached to each facility of the plant 1 and to collect output data.
A database (DB) 40 for accumulating data output from the server, a server 50 for transmitting abnormal data accumulated in the DB to the network, a network,
Here, it comprises a receiving device 70 for receiving abnormal data transmitted from the server 50 via the public line 60, and a drawing DB 80 for connecting to the receiving device 70 and storing an electronic drawing of the plant. When an abnormality occurs in the plant 1, the controller 30 stores, in the DB 40, the abnormality data (abnormal device name, abnormal measurement value, etc.) of the equipment acquired from the connected sensor 10 or actuator 20. The server 50 adds a header that summarizes the protocol and abnormal equipment information according to the receiving device 70 or the line 60 used to the abnormal data stored in the DB 40 and transmits the data to the line 60. The receiving device 70 determines the format displayed on the receiving device screen and the abnormal portion of the equipment from the header information of the received abnormal data. Further, it has a function of searching the drawing DB 80 connected to the receiving device 70 for a corresponding abnormal portion and displaying an alarm for the found drawing and the abnormal portion on the drawing.

Next, the operation of this embodiment will be described according to the flow of abnormal data. A logic for acquiring output data from the connected sensor 10 or actuator 20 and determining whether the output data is an abnormal value is registered in the controller 30 installed in the plant 1.
The controller 30 assumed here has an arithmetic processing unit such as a CPU and a memory for storing a program logic, and has at least an apparatus configuration capable of determining the abnormal value. The controller 30 which has detected the abnormal value immediately transfers the abnormal value to the connected DB 40. In this embodiment, the controller 3
Although the connection method between 0 and the DB 40 is not mentioned, in order to process abnormal data as quickly as possible, short-distance connection or high-speed connection is preferable. Here, the purpose of the abnormal data detected by the controller 30 is DB4.
The transfer to 0 is to prevent the load on the controller 30 from becoming high and is a resource problem of the controller 30. Originally, the purpose of the controller is to send a control signal to an object to be controlled such as an actuator and appropriately control it, and it is considered that the controller does not support processing such as storing abnormal data and transmitting it to a receiving device. Therefore, in the present embodiment, a method is adopted in which the abnormal data detected by the controller 30 is temporarily transferred to the DB 40 and the transmission processing to the receiving device 70 is left to the information system server (not the control system). However, due to the high performance of the controller in recent years, it has become possible for the controller to have a Web server function. In such a high performance controller, the DB 40 and the server 5 as described above are used.
It is not necessary to set 0, and abnormal data can be directly transmitted from the controller to the receiving device.
The server 40 periodically searches the DB 40 and, if there is abnormal data transferred from the controller 30, starts transmission processing to the receiving device 70. here,
Although it was simply stated that "the transmission process is started if there is abnormal data in the DB 40", in an actual system, priority is given to abnormal data transmission, and transmission processing is immediately performed for data that requires urgency, and urgency is set. With respect to abnormal data having a low level, it is possible to perform processing such that the transmission processing is performed after the time series data has been accumulated in the DB to some extent or necessary time series data has been prepared.

The transfer process will be described below with reference to the transfer process flow on the server side shown in FIG. As described above, the controller 30 detects abnormal data (S10) and transfers the data to the DB 40 (S20). In the processing program registered in advance in the server, it is checked whether there is abnormal data to be transmitted to the DB 40 (S3
0). If there is abnormal data to be transmitted, a header is added to the abnormal data (S40). The abnormal data referred to in the present embodiment indicates the identification information of the device in which the abnormality has occurred and the abnormal value output from the device in which the abnormality has occurred. The identification information of the device in which the abnormality has occurred and the abnormal value output from the device in which the abnormality has occurred are acquired by the controller 30 as described above. In addition, here, the header is assumed to be the address of the receiving device that transmits the abnormal data and the protocol information for communication. The address of the receiving device and the protocol for communication are determined by referring to the receiving device table 100 (data registered in advance in the server) as shown in FIG. In FIG. 2, 110 is a machine address of the receiving device, 120 is a communication protocol with the receiving device, and 130 is an example of a transmission level (priority). In the server transmission process, the transmission process according to the transmission level 130 can be performed. In the present embodiment, the transmission priority is higher in the order of A, B, and C,
Also in the transmission processing, processing is performed according to the priority order.

FIG. 3 shows a simplified format of transmission data. In the header addition process (S40), all machine addresses 110 registered in the receiving device table 100 are individually added to the abnormal data 402. Format 40 of such transmission data
By setting 1 to 403, unlike the conventional method, when transmitting abnormal data, it is not necessary to change the transmission data itself according to the display form of the receiving device, and by transmitting the minimum necessary data, It is possible to notify the receiving device at a remote place of the abnormal location of the equipment. For example, in the conventional method, if it is desired to display a web browser on the receiving device, the format that can be displayed on the web browser is H.
TML (Hyper Text Markup Lan)
It had to be converted on the server side to the "guage".
Further, when trying to send image data in order to clearly indicate a detailed abnormal part, it is necessary to embed the address of the image file to be linked in the HTML and also send the image data together. If you want to send abnormal data that requires urgent measures, it is difficult to send a large amount of data as described above at high speed, and in such a case, usually only send rough data of the abnormal part. There are many. As indicated by 403 in FIG. 3, the data to be transmitted can be transmitted by adding a program 403 which gives an action character in addition to the abnormal data and the header.
In this program, the behavior of the transmitted data can be actively described (not affected by the server or the receiving device). As an example of the behavior personality program, while there is no program that automatically judges the load of the line 60 and selects a line with a low load and proceeds to the receiving device or when the receiving device 70 confirms abnormal data, A program for changing to another means or changing the transmission destination to another receiving device can be considered. Like this
By providing the mechanism for adding the program to the transmission data, it becomes possible to transmit abnormal data that is more flexible and reliable than the conventional method. Through the above process, the process of transmitting the final transmission data to the receiving device 70 (S50) is performed. On the plant side, the series of data transmission processes described above are repeatedly performed until an external stop command is issued, and the abnormality occurring in the plant equipment is notified to the receiving device 70 at any time.

Next, based on the processing flow on the side of the receiving device shown in FIG. 5, a mechanism for displaying an abnormal place of equipment after receiving abnormal data will be described. Receiving device 70 here
Is a personal computer or personal digital assistant (PDA)
Or CP such as mobile phones with program execution function
It is premised that the device is a device capable of executing and displaying a program including a U, a memory, a display screen, and the like. Also,
It is assumed that the receiving device has a function and a device for connecting to an external network and receiving data from the outside, and a function and a device for transmitting data of the receiving device itself. First, the data receiving function of the receiving device 70 receives the equipment abnormality data transmitted from the plant (S110). Next, from the data received by the program registered in advance in the receiving device, the header 401 and the abnormal data 402
And the behavior character program 403 is decomposed as required. Furthermore, the above-mentioned program extracts the device information for identifying the abnormal location of the equipment and the abnormal value output from the device from the abnormal data 402. In addition, a corresponding drawing is searched from the drawing DB 80 connected to the receiving device 70 using the extracted device information as a search key (S130). If the corresponding drawing is found, the corresponding drawing is displayed in an appropriate display form according to the receiving device based on the information of the receiving device display form of the header information described above (S14).
0). Furthermore, the drawing management table 20 as shown in FIG.
0 is used to specify the position of the abnormality generating device in the drawing, highlight the circuit portion of the corresponding device in the display drawing, and also display the abnormal value at that time (S1).
50).

FIG. 6 shows a drawing data management structure in the drawing DB 80. It is premised that the drawings stored in the drawing DB 80 in advance correspond to the plant. However, electronic data may be an image obtained by digitizing a drawing drawn on paper with a scanner or the like, or CAD. It may be drawing data created in. In the case of CAD drawing data, most CAD can have facility or device information and circuit coordinates in the drawing as circuit attributes in the drawing data, and therefore such information is used as a key to search for an abnormal location. The result can be displayed. However, in order to display the CAD data, a special program for displaying the CAD data is required on the side of the receiving device. Therefore, in the present embodiment, the image data is adopted as the drawing data. In the case of image data, a special display program is not necessary and can be displayed by a general Web browser in many cases. However, in the case of image data, it is not possible to have information such as equipment or device or circuit display coordinates in the data, so information on equipment or devices corresponding to the circuit diagram in the image and circuit coordinates in the drawing in advance. It is necessary to define a link in a management table different from the image data. The drawing data management configuration of FIG. 6 has a table 20 for managing parent-child relationships of drawings stored in the receiving device.
0 and a table 21 for managing the coordinate definition of the device in the drawing
An example of 0 is shown. The tag name field of table 210 is
This is the identification information of the abnormality detection target device in the drawing specified in the drawing file name field. Further, the coordinate field 210 is a coordinate value indicating at which position in the drawing the abnormality detection target device designated by the tag name field is drawn. The drawing type field of 210 specifies data representing the type of circuit being drawn in the drawing. For example, information such as "instrumentation" is set if the abnormality display target drawing is drawn for the instrumentation circuit, and "sequence" is set if it is drawn for the sequence circuit. The equipment of the plant is drawn by several kinds of drawings even if it is the same equipment, depending on the level of detail of the circuit and the purpose to be shown in the drawing. The information in the drawing type field serves as identification information for indicating in which type of drawing the abnormal portion is displayed. The receiving device of the present embodiment searches for the identification information of the device to be displayed from the tag name field of the table 210 based on the received abnormal data. If there is matching data, the drawing file name including the device displaying the abnormality is acquired from the drawing file name field corresponding to the tag name field, and the drawing is displayed. Further, the location of the abnormal device in the drawing is specified from the coordinate field, and the part of the device is highlighted. However, the above-mentioned direct display of the abnormal part drawing makes it easy for designers and engineers who can decipher the drawing to understand the abnormal part, but for other users, the abnormal part If it is not possible to trace anomalies hierarchically, such as which equipment in the entire plant and which equipment in that equipment,
In some cases, it may not be possible to immediately understand where the abnormal part of the final device is occurring. Also, even if a designer or engineer suddenly displays an abnormal device on a detailed drawing,
It is not always possible to recognize immediately. With respect to such a problem, in the present embodiment, a table 200 for managing a parent-child relationship between drawings as shown in FIG. 6 is prepared. If the parent-child relationship of the drawings is set in advance in the fields of this table 200, the drawings can be traced from the entire plant view to the detailed drawings with abnormalities, or the detailed drawings with abnormalities can be passed through the drawings of the upper hierarchy to the plant. It is also possible to trace to the abnormal location of the equipment in the overall view. At this time, by designating a drawing drawn with the target circuit configuration even in the same device by the data of the drawing type field in the table, it is possible to display the abnormal portion according to the application.

FIG. 7 shows an example of a corresponding drawing display of an abnormal portion retrieved from the abnormal data of the plant equipment received by the receiving device. The user of the receiving device immediately recognizes the facility abnormality location by the drawing 400 automatically displayed on the screen by the transmitted abnormality data after the plant abnormality and the abnormality location 410 highlighted in the drawing. Can be confirmed. In the conventional method, even if a rough abnormal point can be identified by the sent data,
It was difficult to identify such abnormal points at the drawing level. Further, although it is possible to transmit abnormal data at high speed to the receiving device in the LAN, it is difficult to transmit abnormal data in a wide area network such as a public line. In the method according to the present embodiment, the drawing data for identifying and displaying the abnormal portion is arranged on the receiving device side, and
By minimizing the anomaly data to be sent, it is possible to solve the conventional problems, enable high-speed anomaly data transmission using a global network, and automatically identify anomalous points at the drawing level, which leads to plant anomalies. It is possible to take a quicker countermeasure against. Further, since it is not necessary to convert the transmission data itself according to the receiving device, and the data can be transmitted to different receiving devices by exchanging headers, flexibility of abnormal data transmission is created.

Next, FIG. 8 shows another embodiment of the present invention, showing a plant service when the plant maintenance management apparatus of the present invention is used. As shown in the figure, the service using this apparatus is a business between a customer company 601 operating a plant and a plant manufacturer (or a maintenance management specialized company) 600 in charge of maintenance of the plant.

In the process of the diagnostic result creation 613, the diagnostic result creation request sheet received from the abnormal part identification process and the countermeasure method returned from the manufacturer for the identified abnormality and the abnormal device information in the device data file 616 are used to mechanically determine the diagnostic result. To generate. Further, in order to transmit more detailed information to the customer company 601, a related drawing regarding an abnormal portion is mechanically collected from a previously registered plant drawing data file 617 and attached to the diagnosis result. In the process of transmitting the diagnostic result 614, all the diagnostic results are transmitted to the plant where the abnormality has occurred.
(Customer company) 601 is electronically notified. By combining the apparatus of the present invention with the above-described processing (software), it is possible to realize a plant diagnosis service that can mechanically perform from the abnormality of the plant to the generation of a diagnostic result for the abnormality.

On the other hand, the plant maintenance service is realized by adding not only an abnormality notification to this device but also a function of periodically collecting the operating status of the equipment. As for the function to periodically collect the equipment operation status, the hardware can be realized by this equipment described so far, and the operation data of equipment (sensors and actuators) can be compared with the software operating on this equipment. This can be achieved by adding a program that regularly collects. With this device, the operating status (data) of plant equipment is automatically sent from the plant (customer company). The plant maintenance service mechanically analyzes and analyzes the operating status and equipment (equipment) maintenance information managed by the manufacturer, as well as the diagnostic data obtained by plant diagnosis, and equipment that requires periodic inspection and replacement ( Device) automatically

As described above, according to the present invention,
It becomes possible to quickly and accurately transmit the abnormal data of the equipment detected by the plant controller to various receiving devices at remote locations. Furthermore, rather than the conventional rough identification of abnormal places, it is possible to search for abnormal places at the device level drawn in the drawings and easily identify the relevant drawings and specific abnormal places within the drawings. It becomes possible, and quicker response to complicated abnormalities can be realized. In addition, for abnormal data of plant equipment, protocol data according to the type of network that transmits abnormal data and the form displayed on the receiving device, data of the receiving side device that transmits, abnormal points in the drawing Since only the equipment data for specifying is transmitted and the abnormal data itself to be transmitted is not converted, high-speed communication becomes possible. That is,
