Description

[Technical field]

[0001] An embodiment of the present invention comprises: Dam management system, action guideline creation device, and training device Regarding. [Background technology]

[0002] Many dams have been constructed for the purposes of flood control, water supply, agricultural water (irrigation), hydroelectric power generation, etc. Many dams are equipped with dam management control processing systems (also called dam controls) that adjust the amount of discharge according to the amount of inflow. Non-Patent Document 1 published by the Ministry of Land, Infrastructure, Transport and Tourism describes in detail the standard design specifications for dam controls, and future dam controls will be designed in accordance with these specifications.

[0003] As flood damage occurs almost every year all over the country and the effects of climate change become apparent, attention is being paid to dams. Dams have the potential to respond to increased external forces due to climate change, and are therefore being actively discussed at the Council for Social Capital Development and related academic societies.

[0004] In conventional dam management systems, flood control is carried out based on response plans drawn up by humans just before a flood occurs. However, recent environmental changes can bring about extreme heavy rain disasters, often causing dam managers to hesitate in their decisions. Therefore, there is a demand for automating at least some of the planning process to reduce the individual differences in dam managers' decisions and enable more effective flood control.

[0011] [First embodiment] In the first embodiment, a function for creating a behavioral guideline table relating to dam operation will be described. 1 is a functional block diagram showing an example of a dam management system according to the first embodiment. The dam management system according to the first embodiment is a system including a machine-side operation panel 1, an input / output device 2, a reservoir water level measuring device 3, a remote manual operation device 4, a control system LAN (Local Area Network) 5, a first discharge operation device 6, a second discharge operation device 7, an information system LAN 8, an information input / provision device 9, various observation devices 10, and a training device 11.

[0012] Of these, the input / output device 2, the reservoir water level measuring device 3, and the remote manual operation device 4 are connected to a control system LAN 5. In addition, an information input / provision device 9, various observation devices 10, and a training device 11 are connected to an information system LAN 8. A first discharge operation device 6 and a second discharge operation device 7 are connected to both the control system LAN 5 and the information system LAN 8. Here, the first discharge operation device 6 and the second discharge operation device 7 function as redundant systems for each other.

[0013] The machine-side operation panel 1 operates in response to various control signals given from the remote manual operation device 4 via the input / output device 2 to operate the opening and closing of the dam gate, etc. This allows various facilities of the dam to be controlled remotely. Various data showing the status of the dam gate is notified from the machine-side operation panel 1 to the first discharge operation device 6 and the second discharge operation device 7 via the input / output device 2. In addition, the reservoir water level of the dam measured by the reservoir water level measuring device 3 is notified to the first discharge operation device 6 and the second discharge operation device 7 via the control system LAN 5. The first discharge operation device 6 and the second discharge operation device 7 control the machine-side operation panel 1 to operate the discharge of the dam and to control the opening and closing of the discharge gate of the dam.

[0014] The training device 11 includes a training function unit 12 and a behavioral guideline table creation unit 13. Of these, the training function unit 12 includes a training database (DB) 14 and a screen creation unit 15. The training DB 14 holds various data and information necessary for training of related parties including dam operators. In an embodiment, the training DB 14 holds an inflow calculation result file. The inflow calculation result file is a file in which the calculation result of the inflow based on, for example, the rainfall for each hour, the reservoir water level, and the predicted dam inflow value is recorded in a format such as a general-purpose .txt or .csv file. The screen creation unit 15 creates various information provision screens that can be accessed from, for example, a web browser, based on the information acquired from the training DB 14.

[0015] The action guideline table creation unit 13 includes a basic action guideline table DB 16, a detailed action guideline table creation unit 17, and a detailed action guideline table DB 18. The basic action guideline table (operation rules) relating to the operation of the dam is input to the training device 11 via the information input / provision device 9 from a dam manager's PC 19 operated by, for example, the dam manager. The action guideline table creation unit 13 holds the input basic action guideline table in the basic action guideline table DB 16.

[0016] The information input / providing device 9 is connected to the information LAN 8 common to the training device 11, and accepts operations by the dam manager. In other words, the information input / providing device 9 is used to input various information from the dam manager's PC 19 to the dam management system and to provide various information. The information input / providing device 9 controls the display of various information on the liquid crystal panel display (display device) of the dam manager's PC 19, etc.

[0017] The detailed action guideline table creation unit 17 acquires the inflow calculation result file from the training DB 14, and creates a detailed action guideline table by reflecting the contents of the file in the basic action guideline table acquired from the basic action guideline table DB 16. That is, the detailed action guideline table creation unit 17 creates a detailed action guideline table by integrating the acquired inflow calculation result and the basic action guideline table on a common time axis based on a predetermined trigger event. The created detailed action guideline table is stored in the detailed action guideline table DB 18.

[0018] The training DB 14, the basic action guideline table DB 16, and the detailed action guideline table DB 18 are realized, for example, as relational databases, and their actual state is a predetermined storage area in a recording medium such as an HDD (hard disk drive).

[0019] FIG. 2 is a diagram showing an example of the basic action guidelines table. The basic action guidelines table is a schedule showing the timing of work from the start of discharge based on the fluctuation of rainfall and reservoir water level, the organization and operation status, and the work content (gate operation, discharge operation, and sounding of discharge alarm for residents) that each action team (branch chief, deputy branch chief, management team, telecommunications team, general affairs team, public relations team, etc.) should perform in a list. The basic action guidelines table is created based on different operation rules for each dam, and is data unique to each dam. For example, when the system is introduced, the basic action guidelines table is pre-registered in the system using the dam manager's PC 19 and is stored in the basic action guidelines table DB 16. It is required by law that guidelines similar to this basic action guidelines table be determined in advance.

[0020] In Figure 2, multiple rows are arranged vertically in chronological order. The top row shows the work items that should be carried out four hours before the start of discharge. Figure 2 states that the general affairs team should make contact arrangements. It also states that at this time the reservoir water level is above 120EL.m (meters above sea level) and that a flood warning system must be established. From here, the work items that should be carried out at each timing are written on each row, such as two hours before, start of discharge, 30 minutes after discharge, three hours after discharge, and so on.

[0021] 3 is a diagram showing an example of the data structure of the inflow calculation result file. The inflow calculation result file is an array in which time-series rainfall data and current reservoir water level data, and predicted dam inflow values ​​calculated based on these data are recorded for each time. The predicted inflow values ​​are calculated, for example, by a dam inflow calculation unit (not shown) provided in the training function unit 12.

[0022] FIG. 4 is a diagram showing an example of a detailed action guideline table. The detailed action guideline table is a table that collectively shows the tasks that each action team should perform and the time of their execution. The detailed action guideline table file is created by the detailed action guideline table creation unit 17 based on the basic action guideline table file of FIG. 2 and the inflow volume calculation result file of FIG. 3, and is stored in the detailed action guideline table DB 18. This detailed action guideline table file is created in multiple patterns for the same inflow volume calculation result file depending on the difference in the discharge method. In other words, the detailed action guideline table creation unit 17 creates a detailed action guideline table for each different discharge method. Incidentally, there are various discharge methods related to flood control of dams, such as the fixed rate fixed volume discharge method and the fixed volume discharge method.

[0023] In the basic action guideline table of FIG. 2, an event "water level is 120EL.m or more" is registered in the row of the timing four hours ago. On the other hand, referring to the inflow calculation result of FIG. 3, it is predicted that the water level will reach 120EL.m at the time of 19:10. Therefore, the detailed action guideline table creation unit 17 creates a detailed action guideline table as shown in FIG. 4 by merging the basic action guideline table and the inflow calculation result based on the predetermined trigger event of "water level is 120EL.m or more". In other words, when integrating the basic action guideline table and the inflow calculation result, a problem arises as to where to align the common time axis (time). Therefore, by predetermining the trigger event, this problem can be solved.

[0024] FIG. 5 is a flowchart illustrating an example of a processing procedure according to the first embodiment. In FIG. 5, when the dam management system is started in step S1, the detailed action guideline table creation unit 17 acquires the basic action guideline table (FIG. 2) from the basic action guideline table DB 16 in step S2. Next, in step S3, the detailed action guideline table creation unit 17 acquires the inflow calculation result file (FIG. 3) from the training DB .

[0025] In step S4, the information input / providing device 9 displays on the management screen of the dam manager's PC 19 options for selecting one of a plurality of discharge methods conforming to the operation rules. In step S5, the detailed action guideline table creation unit 17 creates a detailed action guideline table file (FIG. 4) according to the discharge method selected by the dam manager. Then, the detailed action guideline table creation unit 17 stores the detailed action guideline table file (FIG. 4) in the detailed action guideline table DB 18.

[0026] As described above, in the first embodiment, a detailed action guideline table, which is a response plan for floods in various cases, can be prepared in advance. This enables not only experienced personnel but also inexperienced dam managers to operate the dam more efficiently under tense circumstances. Therefore, according to the first embodiment, it is possible to enhance the functions for supporting dam operation.

[0027] [Second embodiment] In the second embodiment, an application example to training related to dam operation will be described. In the second embodiment, a detailed action guideline table corresponding to the discharge method to be selected this time is extracted from detailed action guideline tables prepared in advance for a plurality of patterns, and each action team performs training while looking at the extracted detailed action guideline table.

[0028] Fig. 6 is a functional block diagram showing an example of a dam management system according to the second embodiment. In Fig. 6, the action guideline table creation unit 13 further includes a progress status database (DB) 20 and a registered data update / progress confirmation unit 21 as a registered data update processing unit. The progress status DB 20 is a database that holds the progress status (operation history of the dam management system, work progress of each action team, etc.) that is updated each time during training. The registered data update / progress confirmation unit 21 reflects the progress information from the progress status DB 20 in the detailed action guideline table.

[0029] The information input / provision device 9 also distributes the detailed action guideline table to the relevant person terminals 22 (smartphones, tablets, etc.) carried by the relevant people involved in the dam operation (branch chiefs, deputy branch chiefs, members of each action team, etc.). The distributed detailed action guideline table is displayed on the screen of the relevant person terminal 22. When the progress status for the detailed action guideline table is inputted by a user interface using a touchpad or the like, a message indicating the progress status is received by the information input / provision device 9 and transmitted to the progress status DB 20 via the information system LAN.

[0030] 7A and 7B are flowcharts showing an example of a processing procedure in the second embodiment. A procedure for utilizing the detailed action guideline table in training will be described with reference to Figs. 7A and 7B. It is assumed that detailed action guideline tables corresponding to each release method are stored in the detailed action guideline table DB18 in advance.

[0031] In Figure 7A, when the dam management system is started in step S11, in step S12, the detailed action guideline table creation unit 17 obtains the inflow calculation result file (Figure 3) to be used in the current training from multiple past flood data stored in the training DB 14. Next, in step S13, the information input / providing device 9 displays on the management screen of the dam manager's PC 19 options for selecting one of a plurality of discharge methods conforming to the operation rules.

[0032] Next, in step S14, the detailed action guideline table creation unit 17 extracts a detailed action guideline table file (Figure 4) corresponding to the release method selected by the dam manager from the detailed action guideline table DB18, and in step S15, stores it in the training DB14 and displays it on the management screen of the dam manager's PC 19.

[0033] Fig. 8 is a diagram showing an example of a window displayed on the management screen of the dam manager's PC 19. In this window, the extracted detailed action guideline table is displayed together with an [Approve] button for deciding whether or not to adopt this detailed action guideline table.

[0034] FIG. 9 shows the state of the window when the [Approve] button is clicked. In step S16 of Fig. 7A, when the [Approve] button in Fig. 8 is clicked, a dialogue window including a message "Do you want to start training with this action guideline?" opens as shown in Fig. 9. When the dam manager clicks [Yes] (YES in step S17), the information input / provision device 9 distributes the approved detailed action guideline table to the related party terminal 22 in step S18. On the other hand, if [No] is clicked in the dialog window of FIG. 9, the process returns to step S13, and the screen again transitions to the screen for selecting the discharge method.

[0035] Figure 10 is a diagram showing an example of a window displayed on the related party terminal 22. A detailed action guideline table similar to that shown in Figure 8 is displayed on the touch panel of the related party terminal 22. By tapping the touch panel, the user can notify the system of completed work items.

[0036] Returning to Fig. 7A, the explanation will be continued. When the distribution of the detailed action guideline table is completed in step S18, the work items are repeatedly performed in order from the top row of the detailed action guideline table (Fig. 4). The row number is indicated by the variable i, and the processes of steps S19 to S29 (Fig. 7B) are repeated until i reaches 1 to n (the bottom row).

[0037] The release method can be changed as appropriate not only at the start of training but also during training, and if an instruction to change is given, the screen transitions to a screen for selecting the release method again. If the release method selected at the start of training has been changed (YES in step S20), the newly acquired detailed action guidelines table is added in chronological order below the row of the original detailed action guidelines table. If NO in step S20, the processing procedure returns to step S13.

[0038] Returning to Fig. 7B, in step S21, the information input / provision device 9 acquires the progress status of each action team and stores it in the progress status DB. The progress status of each action team carried out based on the detailed action guideline table includes data that can be automatically detected from the training DB, such as operation history data of the dam management system, and data that each team member obtains by operating the related party terminal 22. In step S22, this progress is periodically reflected in the detailed action guideline file (FIG. 4), and the latest detailed action guideline is always displayed on the management screen of the dam manager's PC 19.

[0039] 11 is a diagram showing another example of a window displayed on the management screen of the dam manager's PC 19. This window has an [Update] button for updating the progress status. Fig. 12 is a diagram showing the state of the window when the [Update] button is clicked. When the [Update] button in Fig. 11 is clicked, a dialog window including a message "Do you want to update with this content?" is opened as shown in Fig. 12 (step S23 in Fig. 7B). If the dam manager presses "No" (NO in step S24), the system proceeds to step S25, does not update the progress status in the detailed action guidelines table file (Fig. 4), and sends a confirmation request to the information input source. This is because there may be an error in the information input by each team member or in the automatically acquired dam operation history data.

[0040] If the dam manager clicks [Yes] in step S24 (YES), the process proceeds to step S26, and the system stores the detailed action guideline table file directly in the detailed action guideline table DB18. Next, in step S27, the training DB 14 acquires a detailed action guideline table from the detailed action guideline table DB 18, and in step S28, it is determined whether or not the i-th row of the detailed action guideline table has been input. If the answer is NO in step S28, i is incremented (step S29), and the processes in steps S20 to S28 for the next row are executed.

[0041] When the system confirms that all actions and dam operations of each team member listed in the detailed action guidelines table have been completed for all rows (YES in step S28), the training ends. Thereafter, in step S30, the training DB 14 acquires the detailed action guideline file from the detailed action guideline DB, and in step S31, the training function unit 12 judges the training result. Then, in step S32, the training results are displayed on the management screen of the dam manager's PC 19, and the series of processes ends.

[0042] 13 is a diagram showing an example of a progress status display screen for the detailed action guideline table. This progress status display screen is displayed on the management screen of the dam manager's PC 19 and on the related party terminal 22. The progress status display screen displays buttons ("Complete" / "In Progress" / "Not Yet") for inputting the status for each task item of each team. On the screen before work begins, "Not yet" (white), which means that the work has not yet been handled, is displayed, and then the team members press "In Progress" (yellow) while working, and "Complete" (green) when the work is complete, which is reflected on the progress display screen. Also, if a delay in the progress of one team is such that the next work item of another team cannot be started, all three buttons are displayed as inactive (gray). Note that in Figure 13, the colors of the buttons are differentiated by hatching.

[0043] As described above, in the second embodiment, by using the detailed action guideline table, it is possible to conduct operation training that resembles an actual flood, in conjunction with past flood data, even during normal training to eliminate individual differences in skill among dam managers. Therefore, the second embodiment also makes it possible to enhance the functions for supporting dam operation.

[0044] [Third embodiment] In the third embodiment, an example of application to actual dam operation (actual operation) will be described. Fig. 14 is a functional block diagram showing an example of a dam management system according to the third embodiment. In Fig. 14, the second discharge operation device 7 includes a discharge operation function unit 23 in addition to the action guideline table creation unit 13 similar to that of the second embodiment (Fig. 6).

[0045] The discharge operation function unit 23 includes a discharge operation database (DB) 24 and a screen creation unit 25. The discharge operation DB 24 holds various data and information related to discharge operations, information such as dam control operation history, and inflow volume calculation result files. The screen creation unit 25 creates various information providing screens that can be accessed from, for example, a Web browser, based on the information acquired from the discharge operation DB 24.

[0046] 15A and 15B are flowcharts illustrating an example of a processing procedure according to the third embodiment. In FIG. 15A, when the dam management system is started in step S41, the process proceeds to step S42, where the detailed action guideline table creation unit 17 acquires various data from the discharge operation DB 24. Next, in step S43, the information input / providing device 9 displays on the management screen of the dam manager's PC 19 options for selecting one of a plurality of discharge methods conforming to the operation rules.

[0047] Next, in step S44, the detailed action guideline table creation unit 17 extracts a detailed action guideline table file (Figure 4) corresponding to the release method selected by the dam manager from the detailed action guideline table DB18, and then proceeds to step S45, where it is stored in the release operation DB24 and displayed on the management screen of the dam manager's PC19. Thereafter, in step S46, a display similar to that shown in FIG. 8 and FIG. 9 is displayed, and a dialogue window including a message "Do you want to start operation with this course of action?" is displayed. If the dam manager clicks [Yes] (YES in step S47), the process proceeds to step S48, and the information input / provision device 9 distributes the approved detailed action guideline table to the concerned terminal 22. On the other hand, if [No] is clicked in the dialogue window, the process returns to step S43, and transitions again to the screen for selecting the discharge method.

[0048] When the distribution of the detailed action guideline table is completed in step S48, the processes of steps S49 to S59 (FIG. 15B) are repeated from the top row of the detailed action guideline table (FIG. 4) until i reaches 1 to n (the bottom row).

[0049] The discharge method can be changed as needed not only at the start of training but also during training. If an instruction to change the method is given, the user will be redirected to a screen where the discharge method can be selected again. If the release method selected at the start of the training has been changed (YES in step S50), the newly acquired detailed action guideline table is added in chronological order below the row of the original detailed action guideline table. If NO in step S50, the processing procedure returns to step S43.

[0050] In FIG. 15B, in step S51, the information input / provision device 9 acquires the progress status of each action group and stores it in the progress status DB. In step S52, the progress is periodically reflected in the detailed action guideline file (FIG. 4), and the latest detailed action guideline is always displayed on the management screen of the dam manager's PC 19. After that, in step S53, the same display as in FIG. 11 and FIG. 12 is made, and a dialogue window including the message "Do you want to update with these contents?" is opened. If the dam manager presses "No" (NO in step S54), the system does not reflect the progress in the detailed action guideline file (FIG. 4) and sends a confirmation request to the information input source (step S55).

[0051] If the dam manager clicks [Yes] in step S54 (YES), the process proceeds to step S56, and the system stores the detailed action guideline table file directly in the detailed action guideline table DB18. Next, in step S57, the discharge operation DB 24 acquires the detailed action guideline table from the detailed action guideline table DB 18, and then in step S58, it determines whether or not the i-th row of the detailed action guideline table has been input. If the answer is NO in step S58, i is incremented (step S59), and the processes in steps S50 to S58 for the next row are executed.

[0052] When the system confirms that all actions and dam operations of each team member listed in the detailed action guidelines table have been completed for all rows (YES in step S58), the training ends. Thereafter, in step S60, the discharge operation DB 24 acquires the detailed action guideline table file from the detailed action guideline table DB 18, and in step S61, the discharge operation function unit 23 determines the inflow amount. If the inflow force exceeds the reference value (NO in step S61), the process returns to step S43 in Fig. 15A. If the inflow is equal to or less than the reference value, a message "Flood regime ended" in actual operation is displayed on the management screen of the dam manager's PC 19 (step S62), and the process ends.

[0053] As described above, the same processing procedures as those in Figs. 7A and 7B are carried out, and the discharge operation DB 24 plays the same role as the training DB 14 in the second embodiment. Also, in the second embodiment, the training results are displayed at the end of the training, but in the actual operation of the third embodiment, the results are not judged. The system is terminated when the inflow volume is equal to the outflow volume, or falls below the flood volume predetermined for each dam. If the answer is "NO" in the flow "Is the inflow volume below the standard value?", the dam manager is prompted to select the discharge method again, and operation continues.

[0054] As described above, in the third embodiment, when a flood occurs or other actual operation occurs, a detailed action guideline table corresponding to the discharge method to be selected is extracted from multiple detailed action guideline tables prepared in advance, and each action team operates the dam while looking at this table. During actual operation, each action team can view the action guideline table so that they can act more effectively and efficiently, and progress can be shared by inputting the status at the time of completion of the work. This makes it possible to enhance the functions for supporting dam operation even with the third embodiment.

[0055] [Fourth embodiment] In the fourth embodiment, training outside the operating rules will be described. FIG. 16 is a flowchart illustrating an example of a processing procedure according to the fourth embodiment. In FIG. 16, when the dam management system is started in step S71, the system acquires a basic action guideline table from the basic action guideline table DB in step S72, and holds operation progress data during training as a detailed action guideline table file. Next, in step S73, the system obtains various data, such as past flood data, for training, from the training DB 14.

[0056] Next, in step S74, the information input / providing device 9 displays options for selecting one of all discharge methods, including discharge methods that do not comply with the operation rules, on the management screen of the dam manager PC 19. In response to this, the dam manager selects a desired method from the discharge methods displayed on the screen of the dam manager PC 19. Next, in step S75, the system displays a dialogue window on the management screen, which includes buttons "Yes" and "No" and a message such as "Do you want to start training based on release method XX?".

[0057] If the dam manager clicks [Yes] in the dialog window (YES in step S76), the process proceeds to step S77, and the information input / provision device 9 delivers a detailed action guideline table for the relevant release method to the concerned terminal 22. On the other hand, if [No] is clicked in the dialog window, the process returns to step S74, and transitions again to the screen for selecting all release methods. Then, the process proceeds to step S78, and the training is started in the same manner as in the second embodiment. Here, the detailed action guideline table is not determined in advance, and the release method may be changed at any timing during the training. Furthermore, in addition to changing the release method, the release timing and release amount may also be freely changed within the same release method.

[0058] When the series of operations is completed, in step S79, the training DB 14 acquires a detailed action guideline from the detailed action guideline table DB 18. Then, the system stores the operation history obtained in the training in the training DB 14 as a detailed action guideline table, and ends the training.

[0059] As described above, in the fourth embodiment, operation histories that deviate from the operation rules are tried during training, and the optimal discharge operation history is stored as an "action guideline table." This can provide dam managers with information to consider when developing flexible operation patterns for the increasingly diverse rainfall conditions of recent years.

[0060] That is, in the fourth embodiment, unlike the second embodiment, free training that does not follow the operation rules is carried out, and the optimal operation history obtained as a result of the operation is stored and referred to in the detailed action guideline table DB. In this way, it can be used as a reference material for considering new operation rules. Therefore, the fourth embodiment also makes it possible to enhance the functions for supporting dam operation.

[0061] As described in detail above, according to the first to fourth embodiments, it is possible to provide an action guideline table creation device, a training device, a discharge operation device, and a dam management system that have enhanced support functions for dam operation. The systems disclosed in the first to fourth embodiments can also be expressed as follows. [1] A dam management system (first embodiment) that presents each action team with a detailed action guideline table showing specific task items in chronological order based on current rainfall, reservoir water level and past data. [2] A dam management system (second embodiment) that accumulates the work progress actually performed by the operator according to the work items presented in [1] and the operation history of the dam management system.
