FIG.

  In FIG. 1, the monitoring data management apparatus 100 has the master screen information input from the screen data registration unit 110 in the master screen database 120. When the master screen information is updated, the updated master screen information is displayed on the screen. The data is compressed by the data distribution unit 130 and distributed to the dedicated monitoring terminal 200 and the monitoring data distribution Web server 300 via the communication network 500 such as an in-house intranet. Note that the monitoring data management apparatus 100 actually has monitoring data collected and accumulated from the equipment to be monitored (not shown), and sequentially distributes it to the dedicated monitoring terminal 200 and the monitoring data distribution Web server 300. Although various components are provided, the configuration of this portion is the same as that of the conventional one, and is not described because it is not directly related to the features of the present invention. In addition, also in the dedicated monitoring terminal 200 and the monitoring data distribution Web server 300 described below, the description of the configuration used for normal monitoring is omitted.

  The screen data receiving unit 210 of the dedicated monitoring terminal 200 decompresses the master screen information compressed and distributed by the screen data distribution unit 130 of the monitoring data management apparatus 100 and registers the updated master screen information in the monitoring screen database 220. . The monitoring screen display unit 230 displays a monitoring screen used for normal monitoring using the screen information of the monitoring screen database 220 updated in this way.

  The screen data receiving unit 310 of the monitoring data distribution Web server 300 decompresses the master screen information compressed and distributed by the screen data distribution unit 130 of the monitoring data management apparatus 100, and the updated master screen information is converted into the Web screen conversion unit 320. To pass. The Web screen conversion unit 320 separates the updated master screen information into three types of image data (SVG), structure data (html + css), and operation data (Java Script (registered trademark)) and registers them in the Web monitoring screen database 330. . In response to a request from the Web browser 410 of the Web monitoring terminal 400, the Web screen distribution unit 350 creates Web monitoring screen data used for normal monitoring using the screen information updated and registered in the Web monitoring screen database 330. The data is distributed to the Web browser 410 of the Web monitoring terminal 400 via a communication network 510 such as the Internet or a telephone line. In this way, the monitoring screen used for normal monitoring is displayed on the window screen of the Web browser 410 of the Web monitoring terminal 400.

  Next, the operation will be described. As described above, when the master screen database 120 of the monitoring data management apparatus 100 is updated, the monitoring screen database 220 of the dedicated monitoring terminal 200 and the Web monitoring screen database 330 of the monitoring data distribution Web server 300 are updated. Since it exists, it abbreviate | omits and here demonstrates especially the operation | movement of the web screen conversion part 320 in detail based on the flowchart of FIG. In step ST001, a part (object) such as a symbol or a control button included in the updated master screen information is extracted, and if there is an unscanned part, determination of the part is started. In step ST002, it is determined whether the component has an operation function such as transition to another screen or control of the monitoring target device. If there is an operation function, the operation function included in the component is determined in step ST003. Separated and added to operation data (Java Script). In step ST004, the arrangement position on the screen of the component and the display priority are extracted and added to the structure data (html + css). In step ST005, image data such as component symbols and control buttons are separated and added to the image data (SVG). In step ST006, the operations from step ST001 to step ST005 are repeated until scanning of all the components is completed.

  When scanning of all components is completed, in step ST007, the separated data are registered in the Web monitoring screen database 330 in the form of, for example, the screen management table shown in FIG. 3 or the component management table shown in FIG. The screen management table shown in FIG. 3 includes two (S001, S002) component IDs in DISP001, which is the same screen ID, and each holds the display position X coordinate and the display position Y coordinate as% data. . By holding the display position coordinates as% data in this way, the display position relationship of each component (object) can be made the same even if the screen is enlarged or reduced. As for the priority in display, the smaller the numerical value, the higher the priority and the larger the numerical value, the lower the priority. Although this priority may be provided in a fixed manner, it is desirable to change it dynamically according to the state of the equipment to be monitored. The component management table in FIG. 4 defines the presence / absence of a control function and an operation function of each component as “true” and “false”, respectively. As a result, it is clear which part can be controlled by the part including the operation.

  FIG. 5 shows an example in which a Web monitoring screen used for monitoring actual equipment is displayed using the screen management table shown in FIG. 3 and the component management table shown in FIG. In the following description, the components displayed and arranged on the screen are collectively referred to as objects. FIG. 5 shows that the object 11 whose part ID shown in the screen management table of FIG. 3 is equivalent to S001 is displayed at the display position X coordinate 10% and the display position Y coordinate 20% of the Web monitor screen 10. The object 12 whose component ID shown in the screen management table of FIG. 3 corresponds to S002 is displayed at the display position X coordinate 40% and the display position Y coordinate 30%. The display position is registered in the component management table at the upper left corner of the object.

  In the first embodiment, when the master screen database 120 of the monitoring data management apparatus 100 is updated, the monitoring screen database 220 of the dedicated monitoring terminal 200 and the Web monitoring screen database 330 of the monitoring data distribution Web server 300 are updated. Therefore, it is possible to omit the work of individually creating screen information for each monitoring terminal, and it is possible to prevent human error from being mixed manually. Further, only by screen information registration work using the screen registration unit 110 of the monitoring data management apparatus 100, the dedicated monitoring terminal 200 and the monitoring data distribution Web server 300 are in a remote place away from the installation location of the monitoring data management apparatus 100. In addition, all the operations for updating the monitoring screen information of the dedicated monitoring terminal 200 and the monitoring data distribution Web server 300 can be completed, the work can be made efficient, and the screen data is automatically converted, so that the human work The possibility of mistakes can be reduced.

Embodiment 2. FIG.
FIG. 6 is a block diagram showing a schematic configuration of the monitoring control system according to the second embodiment of the present invention, FIG. 7 is an explanatory diagram showing an example of a monitoring screen of the monitoring control system according to the second embodiment of the present invention, and FIG. FIG. 9 is an explanatory diagram showing a case where objects overlap on the monitoring screen of the monitoring control system according to the second embodiment of the present invention, and FIG. 9 eliminates overlapping of objects with priority on the monitoring screen of the monitoring control system according to the second embodiment of the present invention. It is explanatory drawing which shows a case. In the first embodiment, the Web screen distribution unit 350 of the monitoring data distribution Web server 300 performs normal monitoring using the screen information in the Web monitoring screen database 330 in response to a request from the Web browser 410 of the Web monitoring terminal 400. Although the case where the web monitoring screen data to be used is created and distributed to the web browser 410 of the web monitoring terminal 400 has been described, the web monitoring terminal 400 is generally a mobile (mobile) terminal such as a mobile phone or a tablet terminal or a PC (personal computer). ) Or the like having a screen size smaller than that of the dedicated monitoring terminal 200 is used. Therefore, by providing the Web screen generation unit 340 as shown in FIG. 6, the Web browser 410 of the Web monitoring terminal 400 that has requested monitoring screen data. Web monitoring screen that best fits the window screen size It is obtained by allowing test.

  Specifically, when the Web monitoring screen 10 shown in FIG. 5 is reduced to the Web monitoring screen 20 shown in FIG. 7, the objects 11 and 12 are also reduced at the same reduction ratio as the reduction ratio of the screen, and the objects 21 and 22 are reduced. By doing so, it is possible to maintain a relative positional relationship with respect to the entire screen. However, in the case where a character string such as character information or numerical information is displayed on the object, the character size of 8 px is set to the minimum value in order to maintain the readability of the character string, and the object is not further reduced. If this is done, the objects may interfere with each other as shown in FIG. In such a case, the low priority object 11 is not displayed according to the priority of the screen management table shown in FIG. The Web monitoring screen displayed as a result is as shown in FIG. In this way, even when the window screen size of the Web browser 410 of the Web monitoring terminal 400 is small, it is possible to provide a Web monitoring screen that maintains the readability of the character string. In addition, by dynamically changing the priority according to the state of the monitoring target device, an object representing the monitoring target device to be noted can be displayed with the highest priority.

Embodiment 3 FIG.
FIG. 10 is a flowchart showing the operation of the Web screen generation unit of the monitoring control system according to Embodiment 3 of the present invention. In the second embodiment, the case where the Web screen generation unit 340 generates a Web monitoring screen in accordance with the window screen size of the Web browser 410 has been described. An instruction to enlarge / reduce the screen display, which is called a pinch-in / pinch-out operation, is performed by placing two fingers and changing the interval between the two fingers. The operation of the Web screen generation unit 340 when the screen display is dynamically enlarged / reduced will be described with reference to FIG.

  When an instruction to enlarge / reduce the screen display is detected in step ST011, the current screen display range is acquired in step ST012, and in step ST013, the presence / absence of interference of objects within the screen display range is investigated. If there is an object interference in step ST014, the interference is resolved in step ST015 by deleting an object having a lower priority according to the display priority. If there is no interference in step ST014, the process is terminated. With this configuration, it is possible to provide an optimal Web monitoring screen that is free from object interference even with respect to dynamic enlargement / reduction instructions.

Embodiment 4 FIG.
FIG. 11 is a block diagram showing a schematic configuration of a monitoring control system according to Embodiment 4 of the present invention. In the first embodiment, the case where a monitoring screen similar to that of the dedicated monitoring terminal 200 is displayed on the Web monitoring terminal 400 has been described. However, as shown in FIG. 11, a controllable terminal database 360 is provided in the monitoring data distribution Web server 300. Thus, it is possible to provide a monitoring screen according to the control availability setting. Specifically, the controllable terminal database 360 is registered with individual identification information such as the IP address or MAC address of the Web monitoring terminal 400 that is permitted to be controlled. When there is a request from the Web browser 410, it is confirmed whether the requested Web monitoring terminal 400 is a terminal registered in the controllable terminal database 360. If registered, an object with control (true) is registered. If it is displayed but not registered, an object with control (true) is hidden, a Web monitoring screen is generated only with an object without control (false), and distributed to the Web browser 410.

  By configuring in this way, an object with control is not displayed on a general Web monitoring terminal 400 whose solid identification information is not registered in the controllable terminal database 360, and the state of the monitoring target device is viewed (monitored). Since the monitoring target device can be controlled only from an authorized terminal, it is possible to prevent mischief and erroneous control. Although the data registration work to the controllable terminal database 360 may be performed in the monitoring data distribution Web server 300, it is desirable to be able to perform it from the screen data registration unit 110 of the monitoring data management apparatus 100.

Embodiment 5 FIG.
In the fourth embodiment, the case where the individual identification information of the Web monitoring terminal 400 is registered in the controllable terminal database 360 has been described. However, the user ID and the control / monitoring permission as user information are stored in the controllable terminal database 360. Range information may be registered, and the Web screen generation unit 340 may generate a Web monitoring screen with objects in the range permitted by the user ID. In this case, in addition to the effects of the fourth embodiment, As long as they are the same user, it is possible to perform monitoring control within the permitted range regardless of which Web monitoring terminal 400 accesses.

Embodiment 6 FIG.
FIG. 12 is an explanatory diagram illustrating an example of a monitoring screen of the monitoring control system according to the sixth embodiment of the present invention. FIG. 13 is an explanatory diagram illustrating an example of an object before deformation of the monitoring control system according to the sixth embodiment of the present invention. These are explanatory drawings which show the example of an object after deformation | transformation of the monitoring control system in Embodiment 6 of this invention. In the second embodiment, the case where interference between objects on the Web monitoring screen is eliminated by erasing an object having a low priority has been described. However, it is desirable to display an object without erasing it as much as possible. For this reason, when there is a space around the interfered object 11 as shown in FIG. 8, the Web screen generation unit 340 changes the shape of the object like the object 31 shown in FIG. 12 (hereinafter referred to as deformation). A web monitoring screen is generated.

  Specifically, for example, as shown in FIG. 13, the object 11 in FIG. 8 includes three symbol image data representing a valve, a block that displays a numerical value of the valve opening, and a block that displays a set value of the valve opening. If the elements are arranged in the horizontal direction, since there are spaces above and below the object 11, the Web screen generation unit 340 is deformed by rearranging these three elements as shown in FIG. 12 is generated, and the web monitoring screen shown in FIG. 12 is generated using the deformed object 31, thereby eliminating object interference. By using the deformed object in this way, it is not necessary to hide the interfered object, and a small screen space can be used effectively. However, if the object interference is still not eliminated even when the object subjected to such deformation is used, the low priority object is not displayed as in the second embodiment.

Embodiment 7 FIG.
FIG. 15 is an explanatory diagram illustrating an example of an object before the data size reduction of the monitoring control system according to the seventh embodiment of the present invention. FIG. 16 illustrates an example of the object after the data data size reduction of the monitoring control system according to the seventh embodiment of the present invention. FIG. 17 is an explanatory diagram showing an example of an object before the data size reduction of the supervisory control system according to the seventh embodiment of the present invention. FIG. 18 is a data size reduction of the supervisory control system according to the seventh embodiment of the present invention. FIG. 19 is a flowchart showing the operation of the Web screen generation unit of the monitoring control system according to Embodiment 7 of the present invention. In the sixth embodiment, the case where the object interference is eliminated using the deformed object has been described. In the seventh embodiment, the case where an object with a reduced data size is used will be described.

  The web screen conversion unit 320 creates an object with a reduced data size, which will be described below, and registers it in the web monitoring screen database 330 when converting the master screen information into web screen data. As a specific example, for example, when there is an object for displaying the water level of the first reservoir as shown in FIG. 15 and the pump control according to the water level, the first reservoir as shown in FIG. Create an object with a reduced data size that displays only the water level. For example, if there is an object composed of symbol image data representing a pump as shown in FIG. 17 and character string data of the first pump, a simple figure circle and the first pump as shown in FIG. An object with a reduced data size is created by combining the character strings represented by P1. In this way, the Web monitoring screen database 330 holds both normal size image data and reduced size image data with a reduced data size. Note that an object with a reduced data size does not necessarily have to be automatically created by the WeB screen conversion unit 320, and may be created and held in, for example, master screen information.

  Next, the operation of the Web screen generation unit 340 will be described based on the flowchart of FIG. In step ST021, when there is a web monitoring screen data distribution request from the web browser 410 of the web monitoring terminal 400, it is confirmed whether the requesting web monitoring terminal 400 is a portable terminal. Reduced-size image data is acquired from the monitoring screen database 330. In step ST024, structure data and operation data are acquired from the Web monitoring screen database 330. In step ST025, Web monitor screen data matching the window screen size of the Web browser 410 of the request source Web monitor terminal 400 is generated using the acquired reduced size image data, structure data, and operation data. The web monitoring screen data with the reduced data size generated in this way is delivered from the web screen delivery unit 350 to the requesting web browser 410 via the communication network 510. If the request source is not a mobile terminal in step ST021, normal size image data is acquired in step ST023, and then normal size web monitoring screen data is generated in the same manner as described above. To the Web browser 410.

As described above, when the requesting Web monitoring terminal is a mobile terminal, by generating and distributing Web monitoring screen data with a reduced data size, object interference is unlikely to occur even if the screen size is small, and further distribution is performed. Since the amount of data is reduced, even when the communication network 510 with a low communication speed is used, the display of the Web monitoring screen becomes faster, and a Web monitoring screen with a comfortable operation for the monitoring personnel to be used can be provided.
It should be noted that within the scope of the present invention, the embodiments can be freely combined, or the embodiments can be appropriately modified or omitted.
