<First Embodiment>
(Configuration of monitoring screen display device)
FIG. 1 is a schematic diagram showing a configuration of a monitoring screen display device 100 according to the first embodiment of the present invention.

  The monitoring screen display device 100 is installed in a central machine station that supervises and monitors information of a plurality of base machine stations. Server apparatuses 200A to 200N are installed in each base machine station, and “device information” relating to the equipment installed in each machine station is stored in each of the databases 211A to 211N in the server apparatus. The machine is composed of a plurality of facilities, and the facility is composed of a plurality of facilities. Device information is processed for each facility or facility to generate facility information or facility information.

  In the central machine station, the monitoring screen display device 100 in the central machine station has a communication function for communicating with the server devices 200A to 200N in each base machine station in order to monitor information of a plurality of base machine fields. With this communication function, the monitoring screen display device 100 in the general machine yard collects device information and the like stored in the respective databases 211A to 211N in the server devices 200A to 200N in the respective base yard via the communication network 300. To do. The monitoring screen display device 100 stores the collected device information in the memory in the server device 110. The monitoring screen display device 100 displays the device information and the like stored in the memory on the display device 120. Hereinafter, the configuration of the monitoring screen display device 100 will be described in detail.

  The monitoring screen display device 100 includes a server device 110 and a display device 120. The server device 110 includes a logic information storage unit 111, an identification color storage unit 112, a screen design information storage unit 113, a status information acquisition unit 114, a logic success / failure determination unit 115, an identification color reading unit 116, a monitoring screen generation unit 117, and screen data. An output unit 118 is included. The display device 120 includes a screen data acquisition unit 121 and a monitoring screen display unit 122.

  The logic information storage unit 111 is a storage device that stores “logic information” for executing processing applied to state information from a monitoring target in association with a plurality of monitoring targets and a plurality of operation levels. For example, if the equipment in each machine is a monitoring target, the logic information storage unit 111 stores logic information as shown in FIG. Note that priorities are set in advance for the operation levels, and in the example of FIG. 2, the priorities are set in order of operation levels 1 to 7.

  As shown in FIG. 3, the identification color storage unit 112 is a storage device that stores an identification color in association with each operation level.

  The screen design information storage unit 113 is a storage device that stores design information of the monitoring screen on which the name of the monitoring target, the status information of the monitoring target, and the identification color are displayed.

Specifically, as shown in FIG. 4, the screen design information storage unit 113 stores design information of a monitoring screen having a plurality of areas divided into a predetermined size. In the example of the monitoring screen of FIG. 4, for each divided area, the device information display unit H1 that displays the device information to be monitored as it is, the device information is processed based on the logic information, and the identification color according to the operation level The operation level identification unit H2 to be displayed is displayed. For example, when water and sewage facilities are to be monitored, the device information display unit H1 includes digital signals such as device operation / stop, device failure occurrence / recovery, valve opening / closing, water level, flow rate, Information such as valve opening, pump speed, analog signal such as current and voltage, integrated flow rate, integrated value such as integrated power, and the like are displayed. The operation level identification unit H2 displays “normal”, “monitoring required”, “response required”, “urgent response”, and the like according to the operation level, for example. See, for example, it is possible to utilize the technology of JP 2005-21591 3 Pat.

  An example of the details of each area of the screen design is shown in FIG. Here, as the arrangement of information displayed in the divided areas, the operation level identification unit H2 is arranged in the uppermost part, and the device information display part H1 is arranged in other parts other than the uppermost part. The device information display portion H1 is further divided into several groups (eight groups in the example of FIG. 5). Each group has a signal name A1, a unit A2, and a current value A3 if the signals are analog values and integrated values. If it is a digital value signal, a signal name B1 and a symbol B2 indicating the current situation are displayed. For example, when displaying a group of airfield units, first, in the uppermost operation level identifying unit H2, information corresponding to the operation level such as “normal” for the A machine, “necessary action” for the B machine,. When the system unit group of the water treatment facility is displayed, information such as two blowers operating in the first and second systems, no operation in the third system, and so on is displayed. For the operation level identification unit H2, the background portion is displayed in an identification color corresponding to the operation level. Thus, the operation level can be grasped as a large unit by the display of the operation level identification unit H2. On the other hand, in the device information display section H1, items and the like that should be watched preferentially are displayed as information monitored by the operator. In short, the monitoring screen is a screen design that displays the status information of multiple monitoring targets with a sense of unity, so the operator can comprehensively understand the time series status of the machine and facilities, etc. Monitoring becomes possible.

  Note that the number of area divisions can be freely set by setting, but considering that the operator can efficiently monitor, 2 vertical × 2 horizontal, 2 vertical × 3 horizontal, 3 vertical × horizontal Arrangement of about 3, 3 × 4 × 4, 4 × 3 × 4, 4 × 4 × 4 is desirable.

  The status information acquisition unit 114 acquires “status information” from the monitoring target when the server device 110 is powered on. The status information to be monitored is generated by processing the device information existing at each base station.

  Whether the logic success / failure determination unit 115 can execute processing corresponding to the logic information of each operation level stored in the logic information storage unit 111 based on the monitoring target state information acquired by the state information acquisition unit 114. It is to determine whether or not.

  If it is determined by the logic success / failure determination unit 115 that the process corresponding to the logic information of each operation level is executable, the identification color reading unit 116 identifies the data of the identification color corresponding to the operation level. The data is read from the color storage unit 112. The identification color reading unit 116 sends the read identification color data and monitoring target status information to the monitoring screen generation unit 117.

  The monitoring screen generation unit 117 reads the monitoring screen design information from the screen design information storage unit 113, and the state information acquired by the state information acquisition unit 114 and the identification color reading unit 116 are added to the read monitoring screen design information. The information of the “monitoring screen” reflecting the identification color read out by is generated. Specifically, the monitoring screen generation unit 117 displays status information together with an identification color on the operation level identification unit H2, displays information after processing corresponding to logic information is executed, and displays each piece of device information. Generate a monitoring screen that can be displayed individually.

  The screen data output unit 118 sends information on the monitoring screen generated by the monitoring screen generation unit 117 to the display device 120 via a LAN or the like.

  The image data acquisition unit 121 acquires information on a monitoring screen transmitted from the image data output unit 118 of the server device 110.

  The monitoring screen display unit 122 displays information on the monitoring screen acquired by the image data acquisition unit 121.

(Operation of monitoring screen display device)
FIG. 6 is a flowchart for explaining the operation of the monitoring screen display apparatus 100 according to the present embodiment.

  When the power is turned on (S1), the monitoring screen display device 100 acquires status information from the monitoring target (S2). In the example of FIG. 1, device information is collected from the monitoring target server devices 200 </ b> A to 200 </ b> N by the state information acquisition unit 114, and state information is generated based on these device information. The generated state information is sent to the logic success / failure determination unit 115.

  Subsequently, the logic information for each operation level to be monitored is read by the logic success / failure determination unit 115 (S3). Then, in the logic success / failure determination unit 115, processing corresponding to the logic information of each operation level is sequentially executed on the state information sent from the state information collection unit 114. Thereby, the logic success / failure determination unit 115 determines whether or not the process corresponding to the logic information can be executed (S4).

  As a result of the determination by the logic success / failure determination unit 115, when it is determined that the processing corresponding to the logic information of each operation level can be executed, the identification color reading unit 116 converts the identification color data corresponding to the operation level into the identification color. It is read from the storage unit 112 (S4-Yes, S5). When it is determined that processing corresponding to logic information of a plurality of operation levels can be executed, the operation level is determined according to a preset priority order. Then, the identification color data read from the identification color reading unit 116 and the status information of the monitoring target are sent to the monitoring screen generation unit 117.

  Next, the monitor screen generation unit 117 reads the monitor screen design information from the screen design information storage unit 113, and the state information acquired by the state information acquisition unit 114 is added to the read monitor screen design information. And the identification color read by the identification color reading unit 116 is reflected, and the information of the “monitoring screen” is generated (S6).

  Subsequently, the information on the monitoring screen generated by the monitoring screen generation unit 117 is displayed by the monitoring screen display unit 122 (S7).

  In step S4, when it is determined that the processing corresponding to the logic information of each operation level is not executable as a result of the determination by the logic success / failure determination unit 115, error information is generated by the monitoring screen generation unit 117, and monitoring is performed. Error information is displayed on the screen display unit 122 (S4-No, S6, S7).

  Thereafter, the processing of steps S2 to S7 described above is periodically repeated until the monitoring screen display device 100 is turned off or a stop command is sent to the monitoring screen display device 100 (S8).

(Effect of monitoring screen display device)
As described above, according to the monitoring screen display device 100 according to the present embodiment, when the power is turned on, processing corresponding to the logic information of each operation level is executed based on the status information of the monitoring target. If it is determined whether or not the processing corresponding to the logic information of each operation level can be executed, the monitoring screen design shows the status information to be monitored and the identification color corresponding to the operation level. Since the monitoring screen reflected in the information is displayed, a large number of monitoring targets can be efficiently monitored. For this reason, it is possible to reduce the burden on the operator or to efficiently deal with an abnormality or the like occurring at the site.

  In other words, by using the monitoring screen display device 100 according to the present embodiment, it is possible to efficiently monitor a machine place, equipment, equipment, etc. by a small number of operators. In addition, it is possible to roughly grasp the status of multiple machines, facilities, equipment, etc. based on the status information to be monitored, and to grasp the information to be particularly watched by individual equipment information at the same time. Monitoring of machines, facilities, equipment, etc. becomes possible. Furthermore, the number of persons can be reduced in the monitoring of a plurality of machine stations or the monitoring of a plurality of facilities in a large-scale machine station, and a reduction in cost can be expected.

  Further, in the monitoring screen display device 100 according to the present embodiment, a certain standard that is meaningful in units of a certain machine, facility, and equipment is provided, thereby building a logic and displaying information with a sense of unity. Therefore, it is possible to efficiently monitor a plurality of base stations. As a result, it is possible to make the judgment among operators uniform.

  In addition, it is determined whether or not the condition of the individual device information is established based on a certain rule or logic, and if the condition is satisfied, guidance information in which some message registered in advance by an operator or the like is displayed is displayed. A device is also conceivable. However, since the central machine station monitors a lot of device information of a plurality of base machine stations, the guidance information is assumed to have the following disadvantages. In other words, it is necessary to devise a way of writing a word identifying the machine, equipment, etc. in the displayed message content. In addition, there is a possibility that the content level is not unified among the messages. It may be machine level guidance information or device level guidance information. In the first place, it is necessary to register a message to be displayed.

  In addition, when considering supervising a plurality of base stations in the central machine station, the number of points handled by the entire system may be tens of thousands in some cases. Therefore, in order to efficiently monitor the scores of these scales, it is required to aggregate the device information and combine it into meaningful status information to reduce the number of points to be monitored. On the other hand, display of individual device information that is a point to be seen in a unit such as a certain machine place or facility is also required. The monitoring screen display device 100 according to the present embodiment satisfies these requirements.

  As shown in FIG. 7, when the detailed information button D1 in each area is clicked, the monitoring screen display device 100 can display a simple trend graph or a detailed graphic screen related to the corresponding machine or facility. It is also possible to provide a function for transitioning to the above. The trend graph can display a signal that can roughly grasp a time-series trend as information monitored by the operator. Thereby, the operator can grasp more detailed information and operate the device. In the example of FIG. 8, four trends are displayed. In addition, when the status information of the monitoring target is updated, a display unit D2 that displays that new information has occurred may be provided in the portion H2 that displays the status information of the monitoring target. For example, when the display unit D2 is clicked, new information is displayed on the monitoring screen.

  In addition, the monitoring screen display device 100 updates information reflected on the monitoring screen at a predetermined cycle of 1 second or more. In general monitoring screens, information is often updated at a cycle of about 1 second, but when efficiently monitoring the entire information of multiple machines and facilities, the update cycle should be at least 1 second. Therefore, it will be possible to provide more efficient and effective information.

  The monitoring screen display device 100 can also switch and display a plurality of monitoring screens that display different status information and device information at a predetermined update cycle. For example, when there are three monitoring screens, the first screen, the second screen, the third screen, the first screen, and so on are sequentially switched and displayed.

  Further, the monitoring screen display device 100 displays the status information to be monitored and the individual device information on the same screen, so that it is possible to roughly grasp the status of a plurality of machines, facilities, devices, etc. It is possible to simultaneously grasp information to be particularly watched by displaying the device information, for example, information that holds down the point of operation, and it is possible to efficiently monitor the equipment, facilities, devices, and the like. Therefore, for example, when displaying 13 windows of a graphic screen of 12 facilities and a screen displaying status information obtained by processing them, the individual window display becomes smaller, It is possible to avoid the occurrence of overlap.

  In addition, in this embodiment, although there is a part which has explained the water and sewage facilities as an example, as long as it is a screen for monitoring a plurality of machine stations, equipment, devices, etc., it is particularly limited to the water and sewage facilities is not.

<Second Embodiment>

The design information is stored, and the monitoring screen display unit 122S displays the device information of each device at the associated display position on the graphic diagram. In the present embodiment, the same parts as those already described are denoted by substantially the same reference numerals, and repeated description is omitted unless otherwise specified. In addition, the following description is also omitted in the following embodiments.

  For example, according to the monitoring screen display device 100S, as shown in FIG. 9, status information to be monitored is displayed on the display unit H3 at the upper left of the screen, and individual device information J is displayed at a corresponding position on the map. The Therefore, it is possible to easily grasp the relationship between equipment and facilities and their installation locations.

  In other words, in the monitoring screen display device 100S, since the monitoring screen has a sense of unity and the status of the machine place and facility is comprehensively displayed, the operator can be efficiently monitored.

  In general, a plurality of screens are often prepared for graphic diagrams such as a flow diagram, a process diagram, and a map. Even if multiple screens are prepared, assuming that the status information is always located at the top left of the screen, regardless of which screen is being viewed, the status of multiple aircraft, the status of multiple facilities, etc. It can be understood as a unit.

  In addition, when the status information obtained by processing a plurality of pieces of device information based on the logic information is updated and new information is generated, the monitoring screen display device 100S displays a new information on the display unit H3 that displays the status information to be monitored. It may be displayed that information has occurred. In the above example of displaying the four operation levels of “Normal”, “Monitoring required”, “Necessary response”, and “Urgent response”, when the operation level is higher, or the number of operating main units of a certain facility In the example of displaying in a color, it is displayed that new information has been generated, for example, when the number of operating main engines increases. In the example of FIG. 9, the monitoring screen display device 100S displays an inverted triangle mark M when new information is generated. When the inverted triangle mark M is clicked, a transition may be made to a graphic screen that displays information related to the individual signal under the new information that has occurred. As a result, when the number of operating main engines increases, it is possible to quickly transition to a detailed graphic screen as necessary, and it is possible to efficiently monitor the facility and operate each device. Become.

The monitoring screen display device 100T according to the third embodiment of the present invention relates to a rainwater feed pump control facility whose monitoring target is the monitoring target.

  The state information acquisition unit 114T processes the state information based on the device information of the four pumps in the rainwater feed pump control facility. Specifically, for each pump, a preparation completion signal is output when all the conditions included in group A in FIG. 10 or all the conditions included in group B are satisfied. When the preparation completion signal is output, the pump is counted as the operable number. Then, the number of operating pumps and the number of operable pumps are generated as state information.

  As shown in FIG. 11, the logic success / failure determination unit 115T has seven states W1 to W7 set according to the water level of the reservoir. Each of the logic success / failure determination units 115T is based on the number of operating pumps and the number of operable pumps as shown in FIG. The operation level of the states W1 to W7 is output. For example, when the water level state is W1, if the number of operating units is one and the number of operable units is two, a signal indicating that the monitoring level is required at the operation level 3 is output.

  The monitoring screen generation unit 117T generates a pump station monitoring screen as an example of content displayed in the divided areas. When monitoring pump facilities, information that you want to know about such conditions as rainwater pump operation status, rainwater pump failure status, sewage pump operation status, sewage pump failure status, rainwater pump well level, inflow water level, and rainfall It is information that becomes a point in operation.

  The monitoring screen display device 100T according to the present embodiment grasps the rough operation state of the pump facility by the operation level determination in the rainwater pump control described above and simultaneously displays such individual device information. As a result, the operator can perform efficient monitoring.
