Description

  Embodiments of the present invention include a monitoring control device for monitoring and controlling process states of a plurality of monitoring targets having a hierarchical relationship, an information display method applied to the monitoring control device, an information display module, and an information display program, Further, the present invention relates to an information display table for displaying the process state in an easy-to-see manner.

  Conventionally, in a power transmission / distribution network, a water and sewage treatment facility, an industrial plant, a chemical treatment facility, and the like, a monitoring control device is widely used for monitoring and controlling a state in each process. In recent years, with the expansion of IoT, various types of monitoring control have been performed using these monitoring control devices.

  In this type of monitoring control device, the layout of the display screen displayed from the display is devised so that the state in each process can be easily grasped visually.

  For example, as shown in FIG. 27, the sewerage treatment has a hierarchical structure in which a plurality of pump stations are managed by a single management center and a plurality of management centers are monitored by a single sewer office. It is made by multiple facilities.

  Therefore, a tree diagram representing the hierarchical structure of each facility as shown in FIG. 27 is displayed on the display screen of the monitoring control device for monitoring and controlling the state in each process in the sewerage treatment.

  Each facility such as a sewage office, a management center, and a pumping station indicated by a rectangle in the tree diagram of FIG. 27 is referred to as a node. In order to express a hierarchical structure, an upper node is called a parent node, and a lower node is called a child node.

  Then, the process state, the alertness level, and the like are displayed in the vicinity of each displayed node.

  However, when a tree diagram showing a hierarchical structure of a plurality of nodes is displayed from the display as shown in FIG. 27, a play area 1400 in which no information is displayed is displayed between the nodes. The necessary space is inevitably large, and there is a problem that the limited display area of the display cannot be utilized effectively.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a functional block diagram illustrating a configuration example of the monitoring control device according to the first embodiment of this invention.

  That is, the monitoring control device 10 of the present embodiment is a device that performs monitoring control of a plurality of facilities having a hierarchical structure, and includes a communication module 12, a monitoring control device operation module 14, a rendering module 16, and a data acquisition module 18. , Information display module 20, CPU 22, memory 24, display 26, input device 28 (for example, mouse or keyboard), original parameter storage DB (database) 30, visualization target parameter value calculation rule DB 32, hierarchical structure information DB 34 , And a legend correspondence information DB 36.

  With this configuration, the monitoring control apparatus 10 of the present embodiment is a PTT that is a tabular information display table that reflects the monitoring status of monitoring targets such as a plurality of facilities and the hierarchical structure relationship of the plurality of monitoring targets. (Partitioned Tree Table) is displayed from the display 26. In the present embodiment, the objects to be monitored and controlled by the monitoring control device 10 are, for example, a sewage office, a management center, and a pumping station having a hierarchical structure as shown in FIG. However, the monitoring control device 10 of the present embodiment is not limited to the monitoring control of each facility for sewerage treatment as shown in FIG.

  As shown in the example of FIG. 27, the sewerage treatment has a hierarchical structure in which a plurality of pump stations are managed by one management center and a plurality of management centers are monitored by one sewage office. It is made by multiple facilities.

  According to the monitoring control device 10 of the present embodiment, the PPT 1200 as illustrated in FIG. 2 is displayed from the display 26 with each facility as each node so that the hierarchical relationship between the facilities can be easily grasped. Further, in PPT 1200, corresponding nodes are displayed in different colors according to the alertness level of each facility. For example, red is displayed when the alert level is high, yellow is displayed when the alert level is middle, and green is displayed when the alert level is low. In FIG. 2, cells corresponding to red are shown by grid shading, cells corresponding to yellow are hatched, and cells corresponding to green are shown without shading. A method for determining the alertness will be described later.

  In order to achieve such a function, each part of the monitoring control device 10 of the present embodiment has the following configuration.

  That is, the communication module 12 communicates with a field system 40 provided at a field such as a pump station via a communication network 50 including the Internet and a dedicated network.

  The field system 40 includes, for example, a server 42, a plurality of actuators 44 (# 1) to 44 (#n) connected to the server 42, and a plurality of sensors 46 (# 1) to 46 (#) connected to the server 42. #N). In this embodiment, the actuator 44 is used, for example, for driving control of a pump provided in the pump station, and the sensor 46 includes an accumulated ground rainfall, a vertical accumulated rainfall, a water level, a water temperature, a pump discharge pressure, Used for measuring the amount of water discharged by the pump.

  The server 42 receives data acquired by the plurality of actuators 44 (# 1) to 44 (#n) and data detected by the plurality of sensors 46 (# 1) to 46 (#N), and receives a communication network. Communicate to the communication module 12 via 50.

  The communication network 50 includes a LAN such as Ethernet (registered trademark) or a WAN to which a plurality of LANs are connected via a public line or a dedicated line. In the case of a LAN, it is composed of a number of subnets via routers as necessary. In the case of a WAN, a firewall or the like for connecting to a public line is provided as appropriate, but illustration and detailed description thereof are omitted here.

  The data acquired by the actuator 44 and the data detected by the sensor 46 are hereinafter referred to as “original parameters” in the present specification.

  As will be described later, the original parameter is used by the visualization target parameter value calculation unit 204 of the information display module 20 to calculate the value of the visualization target parameter.

  When the communication module 12 receives these original parameters transmitted from the server 42 via the communication network 50, the communication module 12 stores the received original parameters in the original parameter storage DB 30.

  The monitoring control device operation module 14 further includes a selection node related operation execution unit 142.

  The data acquisition module 18 further includes a data acquisition unit 182.

  The information display module 20 further includes a PTT layout calculation unit 202, a visualization target parameter value calculation unit 204, a node narrowing unit 206, and a PTT display unit 208. An information display program for operating the PTT layout calculation unit 202, the visualization target parameter value calculation unit 204, the node narrowing unit 206, and the PTT display unit 208 is, for example, a program recorded on a recording medium such as a magnetic disk, the Internet, etc. It is realized by a computer that reads a downloaded program via the communication network and whose operation is controlled by this program.

  In the monitoring and control apparatus 10 of the present embodiment, the operation of parts other than the information display module 20 is also performed by reading a program recorded on a recording medium such as a magnetic disk or a program downloaded via a communication network such as the Internet. It is realized by a computer whose operation is controlled by this program.

  The monitoring and control apparatus 10 performs (1) a display process of the PTT 1200 and (2) a node selection process from the PTT 1200 by operating each part as described above.

  FIG. 3 is a diagram for explaining the flow of the information display method performed by (1) the information display module 20, and is a data transition diagram showing an outline of the flow of the display process of the PTT 1200. This display processing is classified as a case where the user displays the PTT 1200 for the first time, or a case where the PTT 1200 is updated according to the change of the original parameter value after the PTT 1200 is already displayed. . For this purpose, the monitoring control device 10 requests the server 42 for hierarchical structure information and the current original parameter value (S1), and data is transmitted from the server 42 to the monitoring control device 10 accordingly ( S2) Based on the transmitted data, the monitoring control device 10 constructs display data and initially displays the PTT 1200 from the display 26 (S3). Thereafter, every time there is a change in the original parameter, the changed value of the original parameter is transmitted from the server 42 to the monitoring control apparatus 10 (S4). Based on the new original parameter value, the monitoring control apparatus 10 The display data is updated, and if necessary, the updated PTT 1202 is displayed from the display 26 (S5).

  In order to perform this processing, the data acquisition unit 182, the PTT layout calculation unit 202, the visualization target parameter value calculation unit 204, and the PTT display unit 208 operate in cooperation.

  FIG. 4 shows how the data acquisition unit 182, the PTT layout calculation unit 202, the visualization target parameter value calculation unit 204, and the PTT display unit 208 cooperate to implement the processing of FIG. 3. It is a flowchart.

  As illustrated in FIG. 4, the data acquisition unit 182 performs different processing depending on whether or not the PTT 1200 is initially displayed. That is, when the PTT 1200 is initially displayed (S10: Yes), the hierarchical structure information and the original parameter values necessary for the initial display of the PTT 1200 are acquired from the server 42, and the PTT layout calculation unit 202 and the visualization target parameter value calculation are obtained. The data is sent to the unit 204 (S12). On the other hand, if it is not the initial display (S10: No), only the updated original parameter is acquired from the server 42 and sent to the visualization target parameter value calculation unit 204 (S14). Details of these processes will be described later with reference to FIG.

  The PTT layout calculation unit 202 performs PTT layout calculation based on the hierarchical structure information and the value of the original parameter sent from the data acquisition unit 182 in step S12, and simultaneously creates column affiliation information. And output to the PTT display unit 208 (S16). Details of this processing will be described later with reference to FIG.

  The visualization target parameter value calculation unit 204 calculates the visualization target parameter based on the hierarchical structure information and the value of the original parameter sent from the data acquisition unit 182 in step S12, creates legend affiliation information, and displays the PTT. The data is sent to the unit 208 (S18). Further, the visualization target parameter is calculated based on the original parameter sent from the data acquisition unit 182 in step S14, and the legend affiliation information is updated and sent to the PTT display unit 208 (S19). Details of these processes will be described later with reference to FIG.

  The PTT display unit 208 uses the PTT layout information and column affiliation information sent from the PTT layout calculation unit 202 in step S16, and the visualization target parameter and legend affiliation information sent from the visualization target parameter value calculation unit 204 in step S18. Then, the PTT 1200 as illustrated in FIG. 2 is displayed from the display 26 (S20). One frame in the PTT 1200 is called a cell. The term cell is also used in spreadsheet software and is well known.

  In step S19, the display contents of the PTT 1200 are updated for the cells that need to be updated using the visualization target parameters and the legend affiliation information sent from the visualization target parameter value calculation unit 204 (S22). Details of these processes will be described later with reference to FIG.

  FIG. 5 shows details of the processes of steps S10, S12, and S14 performed by the data acquisition unit 182 as steps S10a, S12a, and S14a. 4 is intended to show data exchange between a plurality of parts (data acquisition unit 182, PTT layout calculation unit 202, visualization target parameter value calculation unit 204, and PTT display unit 208). On the other hand, FIG. 5 describes in detail the flow of processing performed by the data acquisition unit 182. Therefore, it should be noted that the flow of steps S10, S12, and S14 in FIG. 4 does not necessarily match the flow of steps S10a, S12a, and S14a in FIG.

  As shown in FIG. 5, in the data acquisition unit 182, the PTT that is about to be displayed from the display 26 of the monitoring control apparatus 10 is the initial display (S 10: Yes), that is, the monitoring control apparatus 10 has the hierarchical structure information. If 1000 is not held (S10a: Yes), the hierarchical structure information 1000 is received from the hierarchical structure information DB 34 and held on the memory (S12a).

  The hierarchical structure information 1000 includes a node information table 1020 and an inter-node relationship table 1040 as shown in FIG. The node information table 1020 includes a node ID, a node name, a parent node ID, and a child node ID. The node corresponds to each facility such as a sewer office, a management center, and a pump station in FIG. Therefore, the node name is the name of each facility in FIG. 27, and the node ID is the identification number assigned to each facility. The parent node ID is the node ID of its own parent node. For example, since the parent node of the C-center management center is the A section basin sewer office, 1 is entered in the parent node ID column of the C center management center as the node ID of the A section basin sewer office. The child node ID is the node ID of its own child node. For example, since the child node of the D 槻 Management Center is the N 槻 mizu Mirai Center and the O Island Pumping Station, the child node ID column of the D 槻 Management Center has a node ID of 9 for the N 槻 mizu Mirai Center and O 10 is the node ID of the island pumping station.

  The inter-node relationship table 1040 includes a hierarchy ID, a hierarchy name, and a belonging node ID. In the example shown in FIG. 27, for example, the first layer is a sewer office, the second layer is a management center, and the third layer is a pumping station. In order to define such a hierarchical relationship, in the inter-node relationship table 1040, as the hierarchical ID, the first layer is 1, the second layer is 2, the third layer is 3, and the corresponding hierarchical name and belong to it And a belonging node ID which is a node ID.

  Next, the data acquisition unit 182 acquires the value of the original parameter from the original parameter storage DB 30, holds it in the memory 24, and creates the original parameter table 1060 (S14a). Instead of acquiring the original parameters from the original parameter storage DB 30, the original parameters transmitted from the server 42 and received by the communication module 12 may be acquired from the communication module 12. In this case, the original parameter is sent from the communication module 12 to both the original parameter storage DB 30 and the data acquisition unit 182.

  FIG. 5 also shows an example of the original parameter table 1060. The original parameter table 1060 shown in FIG. 5 includes a node ID, a treatable water amount, an accumulated ground rainfall, and a vertical accumulated rainfall. The units of the treatable water amount, the accumulated ground rainfall, and the vertical accumulated rainfall are all (mm / h). The accumulated ground rainfall is an accumulated value of ground rainfall for one hour. The vertical accumulated rainfall is a value obtained by integrating not only the rain falling on the ground but also the amount of raindrops present in the sky at a certain time.

  The data acquisition unit 182 sends the hierarchical structure information 1000 obtained in step S12a to the PTT layout calculation unit 202 and the visualization target parameter value calculation unit 204. Further, the original parameter table 1060 is also sent to the visualization target parameter value calculation unit 204.

  FIG. 6 shows details of the processing in step S16 performed by the PTT layout calculation unit 202 as steps S16a, S16b, S16c, and S16d.

  That is, the PTT layout calculation unit 202 calculates the width and size of each cell of the PTT 1200 with reference to the hierarchical structure information 1000 sent from the data acquisition unit 182 (S16a). In this calculation, first, (i) the width of each column of the PTT 1200 is determined from the maximum number of character strings among the layer name and node name in each layer. Next, (ii) the number of nodes belonging to the lowest layer among the descendant nodes of each node is counted, and the height of each cell of the PTT 1200 is determined by determining the height of the cell of the PTT 1200 for each node. To do.

  Next, the PTT layout calculation unit 202 calculates the relative position of each cell with respect to the upper left cell of the PTT 1200 (S16b). Then, a PTT layout information table 1070 is created based on the results of steps S16a and S16b. As shown in FIG. 6, the PTT layout information table 1070 includes a cell ID, a node ID, an x position, a y position, a width, and a height.

  When such a PTT layout information table 1070 is created for the first time, there is no column affiliation information (S16c: Yes), so the column affiliation information table 1080 is created (S16d). The column affiliation information table 1080 includes a column ID, a column name, and an affiliation node ID as shown in FIG.

  The PTT layout calculation unit 202 sends the PTT layout information table 1070 and the column affiliation information table 1080 created in this way to the PTT display unit 208.

  FIG. 7 shows details of steps S18 and S19 performed by the visualization target parameter value calculation unit 204 as steps S18a to S18f and S19a to S19f. FIG. 4 is intended to show data exchange between a plurality of parts (data acquisition unit 182, PTT layout calculation unit 202, visualization target parameter value calculation unit 204, and PTT display unit 208), 7 describes in detail the flow of processing performed by the visualization target parameter value calculation unit 204. Therefore, the flow of steps S18 and S19 in FIG. 4 and the flow of steps S18a to S18f and S19a to S19f in FIG. Note that does not necessarily match.

  As shown in FIG. 7, when the hierarchical structure information 1000 and the original parameter table 1060 are sent from the data acquisition unit 182, the visualization target parameter value calculation unit 204 calculates the visualization target parameter value calculation from the visualization target parameter value calculation DB 32. A rule is read (S18a, S19a). Next, based on the visualization target parameter value calculation rule, the value of the visualization target parameter of each cell in the lowest layer is calculated from the original parameter table 1060.

  In this embodiment, finally, using the PTT 1200, which is a tabular information display table as shown in FIG. 2, each facility such as a sewage office, a management center, and a pump station is warned. Different colors are displayed according to the degree (warning, caution, normal). Therefore, in this example, the visualization target parameter value calculation rule corresponds to a rule for determining the alertness. For example, in this example, as shown below, the alert level of each child node is determined by a combination of a plurality of conditions considering a plurality of parameters, and the alert level of the parent node is determined as follows. The visualization target parameter value calculation rule is defined so as to be determined from the combination of the alert levels of child nodes.

(Visualization target parameter value calculation rules for child nodes)
-Warning level high Accumulated ground rainfall> = Water volume that can be treated x 80%
-Warning level middle Accumulated ground rainfall <Treatable water x 80% and vertical accumulated rain> = 4kg / m ²
-Warning level low Accumulated ground rainfall <treatable water x 80% and vertical accumulated rain <4kg / m ²
(Visualization target parameter value calculation rule for parent node)
-If all the alert levels of the child nodes are low, the alert level of the parent node is set to low (FIG. 8 (a)).
If at least one of the alert levels of the child nodes is high or all are middle, the alert level of the parent node is set to high (FIG. 8B and FIG. 8C).

  -Otherwise, the alert level of the parent node is set to middle (FIG. 8 (d)).

  Thus, the alertness level of the parent node is not calculated by a simple calculation such as the total value added, but logically by a combination of a plurality of conditions considering a plurality of parameters as described above. It is determined.

  The visualization target parameter value calculation unit 204 calculates the value of the visualization target parameter of each cell in the lowest layer from the original parameter table 1060 based on the visualization target parameter value calculation rule for the child node as described above (S18b). , S19b).

  The visualization target parameter value calculation unit 204 further calculates the value of the visualization target parameter in the parent hierarchy in order based on the visualization target parameter value calculation rule for the parent node as described above (S18c, S19c).

  The visualization target parameter value calculation unit 204 generates a visualization target parameter value result table 1100 as shown in FIG. 7 as a result of steps S18b to S18c and S19b to S19c.

  Next, the visualization target parameter value calculation unit 204 reads the legend correspondence information table 1120 from the legend correspondence information DB 36 (S18d, S19d). The legend correspondence information table 1120 includes a legend ID, a corresponding alertness level, and a name. For example, legend ID = 1 indicates that the color of the cell is red (red), the alertness level is high, and the legend name is “alert”.

  If the legend affiliation information table 1140 does not exist (S18e, S19e: Yes), the visualization target parameter value calculation unit 204 uses the visualization target parameter value result table 1100 and the legend correspondence information table 1120. The legend affiliation information table 1140 is created (S18f). For example, in the legend correspondence information table 1120, the legend ID = 1 is the alertness level = high. The node ID corresponding to the legend ID = 1 in the legend affiliation information table 1140 is written with the node ID of the alert level = high from the visualization target parameter value result table 1100.

  On the other hand, when the legend affiliation information table 1140 exists in steps S18e and S19e (S18e, S19e: No), the visualization target parameter value calculation unit 204 updates the legend affiliation information table 1140 (S19f).

  FIG. 9 shows details of steps S20 and S22 performed by the PTT display unit 208 as steps S20a to S20d and S22a. 4 is intended to show data exchange between a plurality of parts (data acquisition unit 182, PTT layout calculation unit 202, visualization target parameter value calculation unit 204, and PTT display unit 208). On the other hand, since FIG. 9 explains in detail the flow of processing performed in the PTT display unit 208, the flow of steps S20 and S22 in FIG. 4 and the flow of steps S20a to S20d and S22a in FIG. Note that they do not match.

  The PTT display unit 208 receives the PTT layout information table 1070 from the PTT layout calculation unit 202 and receives the visualization target parameter value result table 1100 from the visualization target parameter value calculation unit 204. Further, the legend correspondence information table 1120 is read from the legend correspondence information DB 36. Alternatively, the legend correspondence information table 1120 may be received from the visualization target parameter value calculation unit 204 (S20a).

  Then, using these tables 1070, 1100, and 1120, the color of the cell corresponding to the node from which the visualization target parameter value is obtained is determined (S20b). If the display of the PTT 1200 is the initial display (S20c: Yes), the information is added to the PTT 1200 based on the information of each cell, and is displayed from the display 26 via the rendering module 16 (S20d). On the other hand, if it is not the initial display (S20c: No), the cell corresponding to the updated node ID is identified from the PTT layout information table 1070, the display is updated, and is displayed from the display 26 via the rendering module 16. (S22a).

  Next, an example of updating the PTT display will be described in more detail. Here, for example, a case where the PTT 1200 before update as shown in FIG. 10A is updated to the updated PTT 1204 as shown in FIG. 10B will be described.

  That is, as shown in FIG. 10 (a), since the alertness of the K-unit pumping station was high before the update, the central management center that is the parent node is also a parent node of the central management center. A certain basin sewerage office also has high alertness.

  From this state, it is assumed that the server 42 has notified that the accumulated ground rainfall, which is the original parameter of the K section pumping station (node ID = 6), is 28 mm / h. In this case, the degree of vigilance is low in order to satisfy the condition of accumulated ground rainfall <processable water volume (37.5 mm / h) × 80%. As a result, since the alertness level of all the facilities of the child node of the C-center management center (node ID = 2) is low, the alertness level of the center management center is also low. As a result, the alertness of the A section basin sewerage office (node ID = 1) is also low.

  Thereby, the visualization target parameter value result table 1100a is updated as shown in FIG. In response to this, as shown in FIG. 12, the legend affiliation information table 1140a before update is updated like a legend affiliation information table 1140b.

  In response to this, the updated PTT 1204 is displayed on the display 26 as shown in FIG.

  Note that the PTTs 1200, 1202, and 1204 do not occupy the entire surface of the display 26. For example, as shown in FIG. 13, other information (eg, a map 1300, precipitation intensity distribution) FIG. 1320, the alert notification information 1340, and the rainfall trend graph 1360) are displayed so as to coexist. In addition, the display position and display size of the PTT 1200 on the display 26 are variable in accordance with an operation input using a mouse, a touch panel, or the like.

  Next, FIG. 14 is a flowchart showing an outline of the flow of (2) node selection processing from the PTT 1200. In order to perform this process, the node narrowing-down unit 206 and the selected node related operation execution unit 142 operate in cooperation.

  As illustrated in FIG. 14, the node narrowing unit 206 receives a narrowing operation input by the user, and depending on which of the legend, the column name, and the cell of each node the operation target by the narrowing operation input is 3 The process is performed (S30). That is, when the operation target is a legend, the refinement node list table 1160 (shown in FIG. 15) is updated with reference to the legend affiliation information table 1140 (S32). On the other hand, when the operation target is a column name, the column affiliation information table 1080 is referred to, and the narrowing-down node list table 1160 is updated (S34). Furthermore, when the operation target is a cell of each node, the refined node list table 1160 is updated with reference to the hierarchical structure information 1000 (S36). Thereafter, if the user operation is a node selection completion operation (S38: Yes), the selected node related operation execution unit 142 is triggered, and if not (S38: No), the process ends. Details of these processes will be described later with reference to FIG.

  When the selected node related operation execution unit 142 is triggered by the node narrowing unit 206 in step S40, the selected node related operation execution unit 142 performs processing on all the nodes included in the narrowed node list table 1160. Then, according to the processing contents, if necessary, it communicates with the server 42 via the communication module 12 to request data or control the actuator 44 (S42). Thus, for example, control is performed to display the monitoring camera videos of all nodes together.

  FIG. 15 shows details of the processing of steps S30 to S36 performed by the node narrowing unit 206 as steps S30a to S30b, S32a to S32d, S34a to S34d, and S36a to S36d.

  In step S30, the node narrowing unit 206 receives the narrowing operation by the user, and if this is a narrowing operation by the legend (S30a: Yes), refer to the legend belonging information table 1140 and refer to all the nodes belonging to the legend selected by the user. ID is acquired (S32a).

  On the other hand, in step S30, when the received narrowing operation is not a narrowing operation by a legend (S30a: No) but a narrowing operation by a column (S30b: Yes), the column belonging information table 1080 is referred to, and the user The IDs of all nodes belonging to the selected column are acquired (S34a).

  Furthermore, in step S30, when the received narrowing operation is not a narrowing operation by legend (S30a: No) and is not a narrowing operation by column (S30b: No), the hierarchical structure information 1000 is referred to, and the user The IDs of all nodes corresponding to the selected node and its descendants are acquired (S36a).

  If the refined node list table 1160 is empty after steps S32a, S34a, and S36a (S32b, S34b, S36b: Yes), the node refinement unit 206 adds all acquired node IDs to the refined node list table 1160 ( S32c, S34c, S36c). On the other hand, when it is not empty (S32b, S34b, S36b: No), the node narrowing unit 206 reduces the obtained node ID list and the node ID that exists in only one of the narrowed node list table 1160 to the narrowed node list. Delete from the table 1160 (S32d, S34d, S36d).

  FIGS. 16 and 17 are diagrams illustrating the relationship between each process in FIGS. 5 to 7, 9, and 14 to 15 and data generated and / or referred to in each process.

  A display example of the PTT 1200 displayed from the display 26 by the process (1) described above is shown in FIG.

  As illustrated in FIG. 2, the PTT 1200 is configured in a tabular format for the purpose of visualizing hierarchical structure data. Each cell in the table corresponds to each node. In FIG. 2, the left side (namely, sewer office side) in the figure is the parent hierarchy side, and the right side (namely, facility name side) in the figure is the child hierarchy side. For example, the vertical and horizontal directions may be reversed, and the upper side in the figure may be the parent hierarchy side and the lower side in the figure may be the child hierarchy side.

  The PTT 1200 illustrated in FIG. 2 corresponds to three layers as shown in FIG. 27, and column names are described in the first row. In accordance with the column affiliation information table 1080, the column names are “sewer office”, “management center”, and “facility name” in order from the parent hierarchy side, that is, in ascending order of hierarchy ID. Further, according to the node information table 1020 and the inter-node relationship table 1040, corresponding node names are assigned to the “sewer office”, “management center”, and “facility name”, respectively. Each cell is arranged according to the definition by the PTT layout information table 1070.

  Furthermore, in the PTT 1200 illustrated in FIG. 2, according to the legend correspondence information table 1120, a legend including “alert”, “caution”, and “normal” corresponding to the high, middle, and low alert levels is displayed above the first row. 1210 is displayed. According to the legend correspondence information table 1120, the legend 1210 displays “warning” in red, “caution” in yellow, and “normal” in green.

  Furthermore, each node is displayed in color according to the alertness defined for each node in the visualization target parameter value result table 1100.

  The alertness of each node changes from moment to moment according to the value of the original parameter. The change in the alertness level is reflected in the PTT 1200 by updating the original parameter table 1060 according to the change in the value of the original parameter and updating the visualization target parameter value result table 1100 accordingly.

  Accordingly, for example, when the caution level of the Kishibe pumping station changes from high to low, and accordingly, the caution level of the C center management center and the A section basin sewerage office also changes from high to low, FIG. As shown in (a) to FIG. 18 (b), the display color of the K section pumping station, the C central management center and the A section basin sewerage office is changed from red to green (from grid shading to no shading). Change.

  Thus, according to the present embodiment, the change in the original parameter value of the child node is converted into the value of the visualization target parameter of the parent node, and the PTT 1200 is immediately rewritten to the PTT 1202.

  Next, (2) the outline of the node selection process from the PTT 1200 will be described.

  As described above, when the selected node related operation execution unit 142 is triggered by the node narrowing unit 206 in step S <b> 40, the selected node related operation performing unit 142 performs processing for all the nodes included in the narrowed node list table 1160.

  For example, when narrowing down the “management center” having a high alert level, as shown in FIG. 19, click “alert” in the legend 1210 for the PTT 1200, and in the first line of the PTT 1200, This is done by double-clicking the column name “Management Center” shown. By these operations, “management centers” having a high alertness level are narrowed down.

  And it communicates with the server 42 via the communication module 12, requests | requires data, and controls the actuator 44 (S42). As a result, for example, as shown in FIG. 19B, the monitoring camera images of the “C center management center”, “F pond management center”, and “G 俣 management center” that are the narrowed down “management center” are displayed. Are collectively displayed on the display 26 of the monitoring control device 10.

  Details of such node selection processing will be described using a specific example.

  In the PTT 1200 as shown in FIG. 20 (a), the state where “warning” in the legend 1210 is clicked is shown in FIG. 20 (b). As a result, as shown in FIG. 20C, a narrowed-down node list table 1160a is created from the legend affiliation information table 1140a.

  Next, as shown in FIG. 21 (a), the state where the “management center” in the first line of the PTT 1200 is double-clicked after the “warning” is clicked is shown in FIG. 21 (b). Is shown in By double-clicking “Management Center”, as shown in FIG. 21C, among the node IDs listed in the narrowed-down node list table 1160a, the nodes belonging to the column ID = 2 in the column belonging information table 1080 The ID is narrowed down, and a narrowed-down node list table 1160b is generated.

  As a result, the node IDs = 2, 13, and 14 are narrowed down. Node ID = 2 is the C center management center from the node information table 1020. Although omitted in the node information table 1020 in FIG. 5, node ID = 13 is the F pond management center, and node ID = 14 is the G cocoon management center (see FIG. 22B). .

  Based on this, as shown in FIG. 22 (a), images of the C center management center, the F pond management center, and the G pool management center are displayed on the display 26 of the monitoring control device 10.

  As described above, according to the present embodiment, the user can select a plurality of nodes at a time by selecting a part of the column names in the legend 1210 and the PTT 1200, and by selecting as few nodes as possible. In addition, it is possible to acquire monitoring control information for these nodes.

  As described above, the monitoring control apparatus 10 according to the present embodiment operates the information display module 20 to which the information display method as described above is operated, so that the PTT 1200 as illustrated in FIG. Can be displayed.

  As illustrated in FIG. 2, column names are displayed in the first row of the PTT 1200 in the PTT 1200. Therefore, the user can easily grasp the hierarchical relationship of each node by looking at the PTT 1200. Furthermore, the user can grasp the overall situation with fewer line-of-sight movements than before.

  In addition, in the PTT 1200, since the cells of the nodes in a parent-child relationship are adjacent, the user can see, for example, a state where the display of red (indicated by a grid) is connected in a horizontal line. It is possible to visually and easily grasp the relationship that the alert level of the parent node is increased due to the effect of the alert level of the descendant node being increased.

  Furthermore, according to the tabular PTT 1200, the play area 1400 as shown in FIG. 27 can be eliminated. For this reason, it is possible to visualize and display the visualization target parameter (for example, the alertness level) of the monitoring target over a plurality of layers in a small space. As a result, as shown in FIG. 13, even when a lot of other information is also displayed on the display 26, it is possible to display the other information so as not to be hidden as much as possible.

  Furthermore, according to a change in the value of the original parameter (for example, accumulated ground rainfall) of the child node, the value of the visualization target parameter (for example, alertness) of the parent node can be updated and reflected in the display of the PTT 1200. .

  For example, when the PTT 1200 is in the state shown in FIG. 18 (a), the accumulated ground rainfall of the K section pumping station is reduced, and the warning level of the K section pumping station is changed from high to low. In accordance with the change in the alert level of the K section pumping station, the alert level of the C center management center that is the parent node of the K section pump station is also re-evaluated and becomes high to low. Furthermore, according to the change in the alert level of the C-center management center, the alert level of the A section basin sewerage office, which is the parent node of the C-center management center, is also reevaluated and goes from high to low. In response to this, the information display module 20 can display the updated PTT 1202 from the display 26 as shown in FIG.

  Furthermore, the user can select a plurality of nodes at a time with as few steps as possible by specifying a legend 1210 or a part of a column name in the PTT 1200 displayed on the display 26. It becomes. As a result, for example, as illustrated in FIG. 22A, it is possible to perform an operation for simultaneously displaying monitoring camera images of a plurality of management centers having a high alertness level with a small number of steps.

(Second Embodiment)
A second embodiment of the present invention will be described. This embodiment is a modification of the first embodiment. Therefore, only the points different from the first embodiment will be described below, and redundant description will be avoided. The same parts as those in the first embodiment will be described using the same reference numerals.

  In this embodiment, the display method of the PTT 1200 displayed from the display 26 of the monitoring control device 10 is devised in the first embodiment, and the feature is in the display method of the lowest-order node whose warning level is high. is there.

  That is, as shown in FIG. 23, at the lowest level node (ie, K section pumping station, Q pond water mirai center, R flat pumping station, Y island pumping station, a-suisui mirai center) having a high alertness level. On the other hand, the meter is displayed with a length corresponding to the time length from the time when the alertness level becomes high. In order to recognize the meter display, the background color of the cell of the lowest node having a high alertness level is set to a slightly lighter red, and a horizontal bar graph extending from the left end of the cell is displayed using a darker red color. In FIG. 23, the lattice shading of the horizontal bar graph extending from the left of these nodes is alternatively illustrated by making it dense as shown in FIG. Here, the length of the horizontal bar graph corresponds to the elapsed time length from the time when the alertness level becomes high.

  In order to realize such meter display, the visualization target parameter value calculation unit 204 creates a visualization target parameter value elapsed time information table 1170 and a node visualization setting information table 1180, as shown in FIG.

  FIG. 25 shows a configuration example of the visualization target parameter value elapsed time information table 1170, and FIG. 26 shows a configuration example of the node visualization setting information table 1180.

  The visualization target parameter value elapsed time information table 1170 includes a node ID, a legend ID, a time step measurement start time, and an elapsed time step number.

  The visualization target parameter value calculation unit 204 writes the node ID and the legend ID of the visualization target parameter value elapsed time information table 1170 by referring to the legend affiliation information table 1140. For a node having a legend ID of 1, that is, the alert level is high (in the case of FIG. 25, node ID = 3), the time at which the alert level becomes high is written in the step measurement start time column. .

  Therefore, in the example of FIG. 25, the step measurement start time is “no value” for the node IDs = 1 and 2 whose alertness is not high. The visualization target parameter value calculation unit 204 further writes the number of elapsed time steps from the step measurement start time to a node having a high alertness level (node ID = 3 in the case of FIG. 25).

  The visualization target parameter value calculation unit 204 updates the visualization target parameter value elapsed time information table 1170 every time the original parameter table 1060 is updated.

  In the example of FIG. 25, one time step is 30 seconds. Therefore, 6 time steps shown in FIG. 25 mean that 6 time steps = 3 minutes with the alertness level being high. Note that the value of the time step is variable. Therefore, one time step is not limited to 30 seconds, and other values can be set.

  As shown in FIG. 26A, the node visualization setting information table 1180 includes an initial position (%), a start time step, and an end time step. In FIG. 26A, as an example, the initial position is 50 (%). This means that the meter display starts from the 50% position in the lateral width of the cell toward the right side. That is, as shown in FIG. 26 (b), from the left end of the cell width to the cell center position, which is 50% of the cell width, is always dark red (in FIG. ), Indicating that the meter is displayed in a dark red color (in FIG. 26 (b), a dense grid) between the 50% position and the 100% position (the right end of the cell).

  The start time step corresponds to the cell center position, and the end time step corresponds to the right end of the cell. That is, in the example shown in FIG. 26A, the cell center position corresponds to time step = 0, and the right end of the cell corresponds to time step = 20. As described above, if 1 time step = 30 seconds, 20 time steps correspond to 600 seconds. Therefore, in the cell illustrated in FIG. 26B, the cell center position to the right end of the cell are divided into 20 parts, and while the alertness level is high, every 30 seconds from when the alertness level becomes high, The meter display will expand step by step.

  The visualization target parameter value calculation unit 204 creates and holds such a node visualization setting information table 1180. Unlike the visualization target parameter value elapsed time information table 1170, the node visualization setting information table 1180 is not affected by the value of the original parameter. Accordingly, the visualization target parameter value calculation unit 204 once creates the node visualization setting information table 1180, and thereafter changes the value only when necessary.

  Then, the PTT display unit 208 refers to the visualization target parameter value elapsed time information table 1170 and the node visualization setting information table 1180, and as shown in FIG. 23, for the lowest-order node whose alertness is high. Then, the meter is displayed according to the length from the time when the alertness level becomes high.

  By viewing such a meter display, the user can grasp which lowest node among a plurality of lowest nodes having a high alertness level has the highest alertness level. Become.

  For example, in the example of FIG. 23, the warning level of the K section pumping station, the Q pond water mirai center, the R flat pumping station, the Y island pumping station, and the asuisui mirai center is high. It is Y island pumping station that the warning level became high, and it is easy to grasp that it is in the order of a-suisui mirai center, K section pumping station, R flat pumping station, Q pond water mirai center. it can.

  Also, by entering a non-zero value in the initial position (%) of the node visualization setting information table 1180 and setting the initial position of the meter display to the right side of 0% (that is, the left end of the cell) in the horizontal width of the cell. Even if the elapsed time from the time when the alert level becomes high is short, it is continuously displayed in the same dark red color as the parent node. It does not hinder the ease of grasping the relationship.

  In the above description, the lowermost node having a high alert level has been described. However, the present embodiment is not limited to this, and the lowermost node having a middle alert level is also middle. The present invention can also be applied to the lowest layer node whose alertness is low. Further, the present invention is not limited to the lowest layer node, and can be applied to an arbitrary alertness level for an arbitrary node.

  According to the present embodiment, since the meter display as described above is performed, by viewing the PTT 1204 displayed from the display 26 of the monitoring control device 10 by the information display module 20, the user can view the current status of each node. It is possible to easily grasp how long the alertness has continued.

  In addition, the user looks at the meter-displayed PTT 1204 to determine the order in which the plurality of nodes have reached the current alert level, and at what timing they have the current alert level. It is also possible to easily grasp whether it has occurred.

  Furthermore, these make it easy for the user to predict which node will have the next higher alertness.

  The acquisition module, the parameter value determination unit, the layout determination unit, the display unit, the narrowing-down unit, and the implementation unit in the claims are the data acquisition module 18, the visualization target parameter value calculation unit 204, the PTT layout calculation unit 202, and the PTT in the embodiment. This corresponds to the display unit 208, the node narrowing unit 206, and the selected node related operation execution unit 142, respectively.

However, it is just rotated 90 degrees. In addition, the first row is the highest hierarchy, and the PTT becomes the lower layer as it proceeds to the second and third rows, that is, the row in the above embodiment is a column, and the column is a row. Even PTT is included in the scope of the present invention.
