Further, when executing the initial setting program 44A, the CPU 41 stores the panel ID 44E of the display panel 10 in the host computer 4, and connects the panel ID 44E with store location information 44F and store panel location information 44G described later, Panel specifying information (display device specifying information) capable of uniquely specifying the display panel 10 is generated. Since this panel specifying information includes the addresses of the stores 101 and 102 where the display panel 10 is installed, one display panel 10 is specified from all the display panels 10 included in the display management system 100. Information to get.

The panel arrangement information 44B is information that associates the positions of the master panel unit 2 and the panel unit 3 in the display panel 10 with the IDs of the master panel unit 2 and the panel unit 3 respectively. Further, the panel arrangement information 44B includes information for associating the vertical and horizontal directions of the display panel 10 with the configuration of the display panel 10. Therefore, with reference to the panel arrangement information 44B, the relative position of the other master panel unit 2 and the panel unit 3 with respect to the master panel unit 2 and the arrangement direction of the master panel unit 2 and the panel unit 3 are specified. it can.
The display image data 44 </ b> C is image data displayed on the display panel 10. The image data may be either a still image or a moving image, and in the case of moving image data, corresponding audio data may be added. The storage unit 44 stores a plurality of display image data 44C displayed on the display panel 10 independently of each other. When new display image data is received via the communication interface 47, The storage unit 44 stores the received display image data.
The data distribution program 44D is a program for dividing the display image data 44C according to the configuration of the display panel 10 and individually transmitting the divided image data, control information, and the like to the master panel unit 2 and the panel unit 3. is there.

The panel ID 44E is identification information (ID) unique to the display panel 10 connected to the host computer 4. The panel ID 44E is input by the input unit 45 or automatically generated when the display panel 10 is newly installed and the initial setting program 44A is executed, or is automatically generated. The memory 24 may store in advance separately from the ID of the master panel unit 2 itself.
The store location information 44F is information indicating the location of the stores 101 and 102 in which the host computer 4 is installed. Specifically, the store address (residential display or lot number display), building name, building floor (hierarchy) Number), and information including the place on the floor (room number or tenant number). Further, the store location information 44F may include store identification information unique to the store. This information is, for example, an ID given in the chain at a store where the chain is developed.
The in-store panel location information 44G is information indicating the installation location of the display panel 10 in the stores 101 and 102. Specifically, the direction (four or eight sides) of the wall surface to which the display panel 10 is attached and It is information indicating a place. When the stores 101 and 102 have a plurality of floors, the in-store panel location information 44G includes information for specifying the floor on which the display panel 10 is installed, and when the stores 101 and 102 have a plurality of rooms, The in-store panel location information 44G includes information (room name, room number, etc.) for identifying the room in which the display panel 10 is installed.
When a plurality of display panels 10 are connected to the host computer 4, the host computer 4 stores a panel ID 44E and store panel location information 44G corresponding to each display panel 10.

6A and 6B are diagrams for explaining processing for displaying an image on the display panel 10, FIG. 6A shows a state in which an image is displayed on the display panel 10, and FIG. 6B schematically shows a transmission state of image data for display. FIG.
Image data of an image displayed on the display panel 10 is generated for each master panel unit 2 and panel unit 3 by processing of the CPU 41 of the host computer 4. For example, as shown in FIG. 6A, the host computer 4 divides the display image P into, for example, nine parts according to the number of panel units constituting the display panel 10, and displays each divided part for display. The image data is generated and transmitted. The ID of the panel unit that displays the image data is added to each image data.

Here, a transfer function executed by the master panel unit 2 and the panel unit 3 will be described. In the display panel 10, since the host computer 4 is connected only to the master panel unit 2, image data is transmitted from the master panel unit 2 to each panel unit 3, and control information is transmitted from the panel unit 3 to the host computer 4. For example, control information and image data need to be relayed by the master panel unit 2 and the panel unit 3. Therefore, the master panel unit 2 and the panel unit 3 have a function of transferring control information, image data, and the like.
When the master panel unit 2 receives control information, image data, or the like from the host computer 4 via the communication line 11, the master panel unit 2 refers to an ID added as a destination to the received control information, image data, or the like. If the destination ID is its own ID, the control information and the image data are temporarily stored in the RAM 23 and processed by the CPU 21, for example, a drawing process based on the received image data is executed to display the display panel. Display an image.

On the other hand, when the ID added as the destination to the control information or image data received via the communication line 11 is not its own ID, the master panel unit 2 is connected to all the interfaces 26 to which the panel unit 3 is connected. The control information and image data described above are output.
The master panel unit 2 has information that associates the ID assigned to the panel unit 3 with which interface 26 the panel unit 3 having the ID is connected to. When control information, image data, or the like to be transferred to the interface is received, it may be possible to specify from which interface 26 the control information, image data, or the like should be output.

The panel unit 3 has a function of transferring control information, image data and the like input from any one of the interfaces 35. Among the four interfaces 35, the panel unit 3 includes an interface 35 connected to the master panel unit 2 directly or via another panel unit 3, and an interface 35 connected to the panel unit 3 having the following ID. Information to be specified is stored in the nonvolatile memory 24.
When control information, image data, or the like is input from any of the interfaces 35, the panel unit 3 determines the destination ID. If the ID is an ID unique to the master panel unit 2 (for example, hexadecimal FF), the input control information, image data, and the like are output from the interface 35 connected to the master panel unit 2.
When the destination ID is an ID of a panel unit 3 other than itself, the panel unit 3 receives the input control information, image data, and the like from the interface 35 connected to the panel unit 3 having the next ID. Output. When the destination ID of the input control information or image data matches the own ID, the panel unit 3 stores the input control information or image data in the RAM 33 and processes it by the CPU 31.

In this way, control information, image data, etc. transmitted from the host computer 4 to the panel unit 3 are transferred from the master panel unit 2 to the panel unit 3 as shown in FIG. The data is transferred by the panel unit 3 and reaches the destination panel unit 3. Control information transmitted from the panel unit 3 to the host computer 4 or the master panel unit 2 is transferred by each panel unit 3 in the reverse order of the ID and received by the master panel unit 2. The
For example, the panel unit 3 (ID = 05) in FIG. 6B is not connected to the panel unit 3 having the next ID. Such a panel unit 3 is set to have no transfer destination during the initial setting operation.

FIG. 7 is a diagram illustrating a configuration example of panel specifying information, FIG. 7A is a diagram schematically illustrating a configuration example of panel specifying information, and FIG. 7B is a diagram illustrating a specific example.
The panel specifying information is generated by connecting information indicating the locations of the stores 101 and 102 in which the display system 1 is installed and a panel ID unique to the display panel 10, and each unit in the display panel 10. ID is added. In the display management system 100, the panel specification information 111A (FIG. 2) stored in the display management database 111 and the panel specification information 44H (FIG. 4) stored in the storage unit 44 of the host computer 4 are the same. For example, it is configured as shown in FIG.
The address information shown in FIG. 7A is wide area information (postal code, prefecture name, municipality name, etc.) in the address of the store where the display system 1 is installed, and the building location information is in the store. It is a detailed address for identifying a building, and floor information is information indicating a floor in the building of the store. Such information can be easily obtained by extracting information included in the store location information 44F (FIG. 4) together with the store identification information. Further, the in-store panel location information in FIG. 7A is in-store panel location information 44G (FIG. 4) stored in the host computer 4, and the panel ID is a panel ID 44E (FIG. 4) stored in the host computer 4. Further, the panel unit ID is an ID assigned to each panel constituting the display panel 10.

In other words, the panel specifying information is obtained by connecting the store location information 44F, the in-store panel location information 44G, the panel ID 44E, and the ID of each panel included in the panel arrangement information 44B, so that all of the panel management information 100 is included. This is information that can specify one display panel 10 from among the display panels 10 and specify one master panel unit 2 or panel unit 3 in the display panel 10.
In addition, as shown in a specific example in FIG. 7B, the panel specifying information is simply a comma indicating an address, a number indicating the building hierarchy, a word indicating the installation location of the display panel 10, an ID of the display panel 10, an ID of the panel unit, and the like. It is generated just by connecting and separating them with no special system. For this reason, panel specific information can be generated by processing with a very light load.

Here, when it is not necessary to distinguish the individual master panel unit 2 and the panel unit 3 as the panel specifying information, the last digit of the configurations illustrated in FIGS. 7A and 7B may be removed. In this case, the panel specifying information is information including the store where the display panel 10 is installed, the installation location of the display panel 10 in this store, and the ID of the display panel 10. Also in this case, since one display panel 10 can be specified from all the display panels 10 included in the display management system 100 by the panel specifying information, the effect of the present invention can be sufficiently obtained.
For example, when generating panel specifying information that does not specify the master panel unit 2 and the panel unit 3, the last digit of the configuration illustrated in FIGS. 7A and 7B is set as a special code (for example, 00) indicating a blank. You may do it. In this case, without changing the number of digits of the panel specifying information, it is possible to distinguish between the case where the individual master panel unit 2 or the panel unit 3 is specified and the case where these panel units are not specified.

  FIG. 8 is a flowchart showing the operation of the display management system 100, FIG. 8A shows the operation of the host computer 4, and FIG. 8B shows the operation of the display management server 110. During the operation shown in FIG. 8, the host computer 4 functions as receiving means and display control means, and the display management server 110 functions as image determining means and transmitting means.

  The CPU 41 of the host computer 4 acquires the output value of the sensor 20A at predetermined time intervals by transmitting / receiving control information to / from the control unit 20 of the master panel unit 2 (step S11). When the sensor 20A includes a plurality of sensors, the CPU 41 acquires the output values of all the sensors from the sensor 20A, and generates data in which each output value is associated with the attribute of the output value. For example, when the sensor 20A includes a temperature sensor and a pressure sensor, the CPU 41 associates the output value of the temperature sensor with information indicating that the output value is a temperature value, and outputs the pressure sensor output value. And the information indicating that the output value is a pressure value. Subsequently, the CPU 41 transmits the output value of the sensor 20A acquired in step S11 to the display management server 110 via the communication line 130 together with the panel specifying information 44H (step S12). The panel specifying information 44H transmitted here is panel specifying information 44H for specifying the display panel 10 including the master panel unit 2 that outputs the output value transmitted here and includes the sensor 20A.

On the other hand, the display management server 110 receives the panel specifying information 44H transmitted from the host computer 4 and the output value of the sensor 20A (step S21), and the panel status in the display management database 111 is based on the received sensor 20A. Information 111B is updated (step S22). The panel status information 111B stores the output value of the sensor 20A in association with the panel specifying information 111A. Therefore, when the display management server 110 newly receives the output value of the sensor 20A, the new sensor The panel status information 111B is updated by adding the output value of 20A. The panel status information 111B may include only the latest output value of the sensor 20A or may include past output values. When the host computer 4 transmits to the display management server 110 data that associates the output value attribute with the output value of the sensor included in the sensor 20A, the display management server 110 displays the data in the panel state. You may add to information 111B.
Thereafter, the display management server 110 executes display image determination processing for determining an image to be displayed on the display panel 10 (step S23), and determines an image to be displayed for each display panel 10 included in the display management system 100. To do. Then, the display management server 110 distributes the image control information for designating the image determined in the display image determination process for each display panel 10 to the display management system 100 together with the panel specifying information for specifying the display panel 10 (step). S24). In step S <b> 24, the display management server 110 transmits information in a state where it can be received by all the host computers 4.

  When receiving the information transmitted from the display management server 110 via the communication interface 47 (step S14), the CPU 41 of the host computer 4 determines whether the received information is information addressed to itself (step S15). This determination is performed based on whether or not the panel specifying information included in the received information matches the panel specifying information 44H of the display panel 10 connected to the received information. If the received information is information addressed to itself (step S15; Yes), the CPU 41 selects the image data specified by the received information from the display image data 44C stored in the storage unit 44. Then, the display image data 44C is displayed on the display panel 10 (step S16). In addition, when the panel specifying information included in the received information does not match the panel specifying information 44H of the display panel 10 connected to the CPU 41, the CPU 41 determines that the received information is not information addressed to itself (step S15; No), the process ends.

FIG. 9 is a flowchart showing in detail the display image determination process shown in step S23 of FIG. 8B.
In this display image determination process, the display management server 110 first determines the target display panel 10 (step S31), and acquires the panel specifying information 111A of this panel from the display management database 111. Subsequently, the display management server 110 acquires the corresponding panel state information 111B (step S32), and further acquires the POS data of the store where the target display panel 10 is installed from the POS management server 120 (step S32). S33). Further, the display management server 110 acquires the image selection condition 111C from the display management database 111 (step S33).

  Here, the display management server 110 determines whether or not the acquired panel state information 111B and the POS data have changed since the previous determination of the display image (step S35). S35; Yes) Based on the image selection condition 111C, image data that matches the panel state information 111B and / or POS data is selected (step S36). Thereafter, the display management server 110 generates image control information for designating the selected image data (step S37), and proceeds to step S24 (FIG. 8B).

On the other hand, when the acquired panel state information 111B and POS data have not changed since the previous determination of the display image (step S35; No), the display management server 110 should display on the display panel 10 to be processed. It is determined whether or not a predetermined time has elapsed since the image was last updated (step S38). This determination is performed by comparing the information included in the image display history 111E with the current time. If the predetermined time has already passed (step S38; Yes), the display management server 110 refers to the image display history 111E, and displays the image data that meets the same conditions on the display panel 10 to be processed. Image data different from the currently displayed image data is selected (step S39), and the process proceeds to step S37.
If the predetermined time has not elapsed since the previous image update (step S38; No), the display management server 110 does not change the image data and instructs to continue displaying the current image data. Information is generated (step S40), and the process proceeds to step S24 (FIG. 8B).

Specific processing for selecting image data based on the image selection condition 111C includes the following processing.
(Example 1) When the sensor 20A includes a sensor relating to weather such as a temperature sensor or a pressure (atmospheric pressure) sensor, image data for advertising a product suitable for the weather or season is displayed on the display panel 10. Specifically, an advertisement for a warm beverage or food is displayed when the temperature is low, and an advertisement for a cold beverage or food is displayed when the temperature is high. Also, when multiple output values such as temperature, humidity, and atmospheric pressure are within the range of output values when the weather is rainy, display an advertisement for umbrellas and rain gear, and output values when these multiple output values are clear If it is within the range, display picnic tools, lunch box advertisements, etc.
In this example, a plurality of product advertisement image data is stored as the display image data 44C, and the temperature and humidity ranges and the types of image data to be displayed are associated with the image selection condition 111C. Just keep it. A plurality of image data may be associated with one temperature and humidity range. In this case, the display management server 110 may obtain a temperature or humidity range to which the output value of the sensor 20A belongs, and may randomly select one image data from among a plurality of image data corresponding to this range. At this time, the sensor 20 </ b> A is not limited to the sensor provided in the casing of the master panel unit 2, and may be a sensor installed outdoors in the stores 101 and 102.
In this example 1, it is possible to display advertisements for products that are suitable for the conditions such as temperature and humidity of the stores 101 and 102, that is, the weather and environment, and it is possible to perform effective advertisements and to enhance interest.

(Example 2) When the sensor 20A includes a sensor for detecting the presence or absence of a person or the number of persons in front of the display panel 10 by infrared rays or the like, image data corresponding to the presence or absence of a person or the amount of the image data is displayed. To display. Specifically, when there are few people, an image that calms people's feelings is displayed, and when there are many people, an image that gives a vibrant image is displayed. In this example, the range of output values of the human sensor and the type of image data to be displayed may be associated with the image selection condition 111C. In this example 2, it is possible to expect an effect of increasing the comfort in the stores 101 and 102 by displaying an image that gives a favorable impression according to the number of people in the stores 101 and 102.

In addition, when the sensor 20A includes a weather sensor such as a temperature sensor or a pressure (atmospheric pressure) sensor, and a sensor that detects the presence or absence of a person in front of the display panel 10 by infrared rays or the like, You may select an image based on the conditions which combined the detection value of these sensors.
Further, based on the POS data held by the POS management server 120, for example, an advertisement for a product whose sales are conspicuously sluggish compared to other stores is displayed, or sales tend to increase in the last week. You may make it display many advertisements of a hot selling product.
Furthermore, a comparison with the output value of the sensor 20A in another display panel 10 may be performed, and when the comparison result satisfies a predetermined condition, an image suitable for this condition may be displayed.
The condition may be determined with priority given to either the output value of the sensor 20A or the POS data stored in the POS management server 120, or the condition may be determined by combining both. Image control information for displaying the selected images in order may be transmitted from the display management server 110.

The image control information transmitted from the display management server 110 is not limited to information specifying one image data to be displayed, but a plurality of image data, a display order of the plurality of image data, a display time of each image data, and the like. May be display schedule data.
Further, as the display image data 44C, a plurality of programs (programs) including a plurality of image data and information defining the display order of the plurality of image data are stored, and information specifying the programs is stored in the display management server. 110 may be transmitted to the host computer 4.

  As described above, according to the embodiment to which the present invention is applied, the image to be displayed on each display panel 10 is determined by the display management server 110 according to the image selection condition 111C stored in the display management database 111. Display control information for displaying the determined image is transmitted to the host computer 4 together with panel specifying information for uniquely specifying the display panel 10, and the host computer 4 receives the information transmitted from the display management server 110. When the received information includes panel specifying information for specifying the display panel 10 to which it is connected, an image is displayed on the display panel 10 based on the display control information. The image to be determined is appropriately determined according to the display conditions, and the determined image is easily displayed on each display panel 10. Rukoto can.

  In addition, if the panel specifying information transmitted from the display management server 110 is not the panel specifying information 44H corresponding to the display panel 10 to which the host computer 4 is connected, the host computer 4 displays the display control information transmitted together with the panel specifying information. The operation based on is not performed. For this reason, even if the same information is transmitted to a large number of host computers 4, the display on one display panel 10 specified by the panel specifying information can be reliably controlled. That is, even if information is transmitted from the display management server 110 to all the host computers 4, each host computer 4 determines whether the information is addressed to itself based on the panel specifying information included in the information. it can. For this reason, even if the display management server 110 does not specify the transmission destination, only the target host computer 4 operates based on the information, so that the display on each display panel 10 can be controlled extremely easily and reliably. it can.

Further, the display management server 110 determines an image to be displayed on each display panel 10 based on the detection state of the sensor 20A included in each display panel 10 and the image selection condition 111C. An image suitable for the state of the installation location is displayed. Thereby, a plurality of display panels 10 are individually controlled, and display control with expressive power rich in interest and practicality can be performed.
Further, POS data is transmitted from the POS terminal 5 in each store 101, 102 to the POS management server 120, the POS management server 120 stores the POS data, and the display management server 110 displays each display panel obtained from the POS data. Since the image to be displayed on each display panel 10 is determined on the basis of the image selection condition 111C in accordance with the sales amount and sales status at the store where 10 is installed, or the type of the best-selling product, each display panel In 10, an image suitable for the situation of the store is displayed. Thereby, the display control reflecting the sales situation of a store can be performed by individually controlling the plurality of display panels 10.

  The host computer 4 stores a plurality of display image data 44 </ b> C displayed on the display panel 10 in the storage unit 44, and the display management server 110 specifies image data to be displayed on each display panel 10. The host computer 4 reads the image data specified by the information transmitted together with the panel specifying information for specifying the display panel 10 to which the host computer 4 is connected, and displays it on the display panel 10. Let Therefore, the image displayed on each display panel 10 can be easily controlled by the display management server 110, and it is not necessary to transmit the image data itself from the display management server 110 to the host computer 4. The amount of data transmitted and received via 130 can be kept extremely small. Therefore, resources related to communication can be saved, and the processing load and time required for information transmission from the display management server 110 can be shortened, and the load on the display management server 110 can be kept low.

  In the above embodiment, as shown in step S24 and step S14 of FIG. 8, information for designating an image is transmitted from the display management server 110, and based on this information, the host computer 4 displays image data for display. 44C is selected and displayed on the display panel 10. However, the present invention is not limited to this, and image data itself displayed on the display panel 10 from the display management server 110 to the host computer 4 is not limited thereto. You may send it. In this case, there is no restriction on the image to be displayed on the display panel 10, and for example, image data not previously stored in the storage unit 44 can be displayed on the display panel 10, and the degree of freedom is very high. In addition, since the host computer 4 does not need to store the display image data 44C, there is an advantage that resources of the host computer 4 can be saved.
