[0009] <Embodiment> <Configuration> FIG. 1 is a diagram illustrating an example of a water treatment plant that is a target of operation support by an operation support device according to an embodiment.

[0010] As shown in Figure 1, filtered water is stored in a clean water reservoir, and the water stored in the clean water reservoir is sent to an regulating reservoir and other locations by a water supply pump. Four water supply pumps are installed in System I, and for example, up to two water supply pumps can be operated simultaneously to send water from the clean water reservoir to the regulating reservoir. Three water supply pumps are installed in System II, and for example, one water supply pump can be operated to send water from the clean water reservoir to within the city.

[0011] FIG. 2 is a block diagram illustrating an example of a configuration of a driving assistance device according to an embodiment.

[0012] As shown in FIG. 2, the driving assistance device includes a time series data acquisition unit 1, a constraint information acquisition unit 2, a time series data editing unit 3, a simulation execution unit 4, a display control unit 5, an input / output device 6, and a feature-added time series data recording unit 7.

[0013] The time series data acquisition unit 1 acquires time series data from the feature-added time series data recording unit 7 or the time series data recording unit 9. The time series data is monitoring and control data collected from the water treatment plant by a monitoring and control device that monitors the water treatment plant, and is recorded in the feature-added time series data recording unit 7 or the time series data recording unit 9. Examples of the time series data include the water supply flow rate in the I system, the water supply flow rate in the II system, the total filtration flow rate, the water distribution flow rate to the regulating pond, the power received by the water treatment plant, the water level of the purified water pond, the water level of the regulating pond, and the base power of the water treatment plant other than the water supply pump. Note that each of the water supply flow rate in the I system, the water supply flow rate in the II system, the total filtration flow rate, and the water distribution flow rate to the regulating pond may be a flow rate that takes into account at least one of the season, the day of the week, the weather, the temperature, and an event. Details of the feature-added time series data recording unit 7 will be described later.

[0014] The constraint information acquisition unit 2 acquires constraint information corresponding to the time series data from the feature-added time series data recording unit 7 or the input / output device 6. Examples of the constraint information include an upper limit of the received power (a peak set value of the received power), upper and lower limits of the water level of the clean water reservoir, and upper and lower limits of the water level of the regulating reservoir. The values ​​of each piece of constraint information may be corrected by inputting them from the input / output device 6 by an operator, or may be acquired from a constraint information database if one is available.

[0015] The time series data editing unit 3 edits at least a part of the time series data acquired by the time series data acquiring unit 1 to generate edited time series data.

[0016] The simulation execution unit 4 executes a simulation of the behavior of the water treatment plant based on the edited time series data created by the time series data editing unit 3 and the time series data, and calculates first simulation time series data which is a simulation result corresponding to the edited time series data, and second simulation time series data which is a simulation result corresponding to the time series data.

[0017] The display control unit 5 controls the input / output device 6 to display the first simulation time-series data, the second simulation time-series data, and the constraint information.

[0018] The input / output device 6 includes a display device and displays, for example, the first simulation time-series data, the second simulation time-series data, and the constraint information under the control of the display control unit 5. The input / output device 6 also includes an input device and accepts, for example, an operator's input related to editing by the time-series data editing unit 3.

[0019] FIG. 3 is a block diagram for explaining the time-series data recorded in the feature-added time-series data recording unit 7. As shown in FIG.

[0020] FIG. 3 illustrates a monitoring control device 8, a time series data recording unit 9, a feature calculation unit 10, a feature calculation logic recording unit 11, an input / output device 12, and an additional information adding unit 13 as a configuration for recording time series data in the feature-added time series data recording unit 7.

[0021] The time series data recording unit 9, the feature amount calculation unit 10, the feature amount calculation logic recording unit 11, the input / output device 12, and the additional information adding unit 13 may be provided in a device separate from the monitoring control device 8. Also, the time series data recording unit 9, the feature amount calculation unit 10, the feature amount calculation logic recording unit 11, the input / output device 12, and the additional information adding unit 13 may be provided in the driving support device shown in Fig. 1. In this case, the input / output device 12 shown in Fig. 3 may be the same as the input / output device 6 shown in Fig. 2.

[0022] The monitoring and control device 8 collects monitoring and control data including measurement information output by measuring instruments installed in the water treatment plant and control input information input by an operator, and records the collected monitoring and control data as time-series data in the time-series data recording unit 9. In addition, the monitoring and control device 8 transmits the control input information input by the operator to each piece of equipment that constitutes the plant.

[0023] The feature amount calculation logic recording unit 11 records feature amount calculation logic for calculating feature amounts from the time series data recorded in the time series data recording unit 9 .

[0024] The feature amount calculation unit 10 calculates feature amounts from the time series data recorded in the time series data recording unit 9 based on the feature amount calculation logic recorded in the feature amount calculation logic recording unit 11. For example, the feature amount calculation unit 10 calculates feature amounts by performing differential or integral processing for a predetermined time on the measurement values ​​in a water treatment plant recorded as time series data in the time series data recording unit 9. At this time, the feature amount calculation logic recorded in the feature amount calculation logic recording unit 11 specifies what processing should be performed on which measurement value.

[0025] The feature-added time series data recording unit 7 records the time series data recorded in the time series data recording unit 9, the feature calculated by the feature calculation unit 10, and the feature added by the additional information adding unit 13 in association with each other.

[0026] The additional information adding unit 13 records the additional information input by the operator via the input / output device 12 in the feature-added time-series data recording unit 7 or the time-series data recording unit 9. Specifically, the operator inputs information that the monitoring and control device 8 has not collected from the water treatment plant as additional information. Examples of information that the monitoring and control device 8 has not collected from the water treatment plant include the season, day of the week, weather, temperature, and events that affect the operation of the water treatment plant.

[0027] The input / output device 12 includes a display device and displays, for example, the time series data recorded in the feature-added time series data recording unit 7 or the time series data recording unit 9. The input / output device 12 also includes an input device and accepts, for example, an operator's input related to features or additional information to be added to the time series data.

[0028] In addition, in FIG. 2, the time series data acquiring unit 1 may acquire time series data to which no feature quantity has been added from the time series data recording unit 9 shown in FIG. 3, and the time series data acquiring unit 1 may acquire time series data to which additional information has been added by the additional information adding unit 13 from the time series data recording unit 9 shown in FIG. 3.

[0029] <Operation> FIG. 4 is a flowchart showing an example of the operation of the driving support device.

[0030] In step S11 , the time-series data acquiring unit 1 acquires time-series data from the feature-added time-series data recording unit 7 or the time-series data recording unit 9 .

[0031] In step S12, the constraint information acquisition unit 2 acquires constraint information corresponding to the time series data from the featured time series data recording unit 7. More specifically, the constraint information acquisition unit 2 acquires constraint information corresponding to the second simulation time series data. Here, when the time series data is acquired from the time series data recording unit 9, the constraint information corresponding to the time series data is acquired from the input / output device 6.

[0032] In step S13, the time series data editing unit 3 creates edited time series data by editing at least a part of the time series data acquired by the time series data acquiring unit 1. More specifically, the time series data editing unit 3 creates edited time series data by editing at least a part of the time series data acquired by the time series data acquiring unit 1 in accordance with an operation related to editing the time series data input by an operator via the input / output device 6.

[0033] In step S14, the simulation execution unit 4 executes a simulation of the behavior of the water treatment plant based on the edited time series data created by the time series data editing unit 3 and the time series data, and calculates first simulation time series data which is a simulation result corresponding to the edited time series data, and second simulation time series data which is a simulation result corresponding to the time series data.

[0034] In step S15, the display control unit 5 controls the input / output device 6 to display the first simulation time series data, the second simulation time series data, and the constraint information. The first simulation time series data, the second simulation time series data, and the constraint information are displayed on the input / output device 6.

[0035] <Example> 5 and 6 are diagrams showing an example of a screen displayed on the input / output device 6 when the time series data editing unit 3 edits the edited time series data. When an operator inputs an arbitrary search condition (date and time, etc.) via the input / output device 6, the screen shown in FIG.

[0036] The left screen of Figures 5 and 6 displays time series data for "Line I water supply flow rate," "Line II water supply flow rate," "Total filtered flow rate," "Regulation reservoir water supply flow rate," and "Other electricity."

[0037] The right screen of Figures 5 and 6 displays time series data for "I system water supply cumulative flow rate," "received power," "clean water reservoir water level," "regulating reservoir water level," and "total number of pumps started." Each time series data displays constraint information (hatched areas in the figures). Note that the constraint information for "I system water supply cumulative flow rate" is set based on the upper and lower limit values, which are the constraint conditions for the clean water reservoir water level, and the upper and lower limit values, which are the constraint conditions for the regulating reservoir water level.

[0038] The circles on the left side of "clean water reservoir water level" and "regulating reservoir water level" indicate the initial water levels. The initial water levels may be set arbitrarily by the user, or the current water level (real-time water level) recorded in the time-series data recording unit 7 with added features or the time-series data recording unit 9 may be set as the initial water level.

[0039] The dashed lines displayed vertically on the left and right screens of Figures 5 and 6 indicate the time selected by the operator. The "Date and Time" shown in Figures 5 and 6 displays the date and time indicated by the dashed lines. These two lines are linked, so the operator can select any time by moving the line on either the left or right screen horizontally. The value of each time series data at the time selected by the operator is displayed as a value enclosed in a square at the right end of each time series data.

[0040] In the time series data of "received power" shown in Figure 6, the received power at the time indicated by the dashed circle exceeds the constraint information (upper limit of received power). This is because the timing of water supply from System I and System II is the same at the time indicated by the dashed circle, and the total number of water supply pumps operating at that time is three.

[0041] In order to make the received power at the time indicated by the dashed circle in the time series data of "received power" shown in Fig. 6 satisfy the constraint information (do not exceed the upper limit), the operator performs an operation (editing) to lower the water flow rate at the time indicated by the dashed circle in the time series data of "I system water flow rate" in Fig. 6. At this time, the time series data of "I system water flow rate" operated by the operator corresponds to the edited time series data created by the time series data editing unit 3.

[0042] FIG. 7 is a diagram showing an example of a screen displayed on the input / output device 6 after the simulation execution unit 4 executes the simulation.

[0043] As shown in Figure 7, when the operator performs an operation to reduce the water supply flow rate at the time indicated by the dashed circle in the time series data of "I system water supply flow rate", the received power at the time indicated by the dashed circle in the time series data of "received power" falls below the upper limit and satisfies the constraint information. At this time, the time series data of "I system water supply flow rate" operated by the operator (edited time series data) is displayed as the first simulation time series data. In addition, the time series data affected by the operation of the time series data of "I system water supply flow rate" is displayed as the second simulation time series data.

[0044] In this way, the first simulation time-series data, the second simulation time-series data, and the constraint information are displayed on the screen showing the simulation results. Furthermore, the second simulation time-series data and the constraint information are displayed in an overlapping manner.

[0045] Information regarding how time-series data changes when the time-series data is edited may be held by the simulation execution unit 4 or may be stored in a storage unit (not shown).

[0046] When the simulation execution unit 4 determines that the second simulation time series data does not satisfy the constraint information, the display control unit 5 may control the input / output device 6 to display a warning (e.g., display a pop-up screen) to inform the user that the second simulation time series data does not satisfy the constraint information.

[0047] As a result of the simulation performed by the simulation execution unit 4, there is a possibility that other time series data will not satisfy the constraint information. In this case, the operator performs further operations to change any of the time series data, and the time series data editing unit 3 creates edited time series data based on the operator's operations. The simulation execution unit 4 then performs a simulation based on the edited time series data and the time series data. By repeating such operations, it is possible to obtain time series data that satisfies all of the constraint information more efficiently.

[0048] <Effects> The driving assistance device according to this embodiment displays first simulation time series data, which is a simulation result corresponding to the edited time series data created by the time series data editing unit 3, second simulation time series data, which is a simulation result corresponding to the time series data affected by the edited time series data, and constraint information. In particular, the second simulation time series data and the constraint information are displayed in an overlapping manner. This allows the operator to obtain time series data that satisfies all of the constraint information. Furthermore, the driving assistance device can provide appropriate driving assistance to the operator.

[0049] <Modification> In the above, the case where the time series data editing unit 3 creates edited time series data based on an operation by an operator has been described, but the present invention is not limited to this.

[0050] For example, the time series data editing unit 3 may have an AI (Artificial Intelligence) function. In this case, the time series data editing unit 3 edits at least a part of the time series data so as to satisfy the constraint information, and creates edited time series data. The subsequent operations are the same as those described above. This makes it possible to automatically calculate time series data that satisfies all of the constraint information.

[0051] <Hardware configuration> The functions of the time series data acquisition unit 1, the constraint information acquisition unit 2, the time series data editing unit 3, the simulation execution unit 4, and the display control unit 5 in the operation support device (see FIG. 2) described in the embodiment are realized by a processing circuit. That is, the operation support device includes a processing circuit for controlling the following: acquiring monitoring and control data collected from the water treatment plant by a monitoring control device that monitors the water treatment plant as time series data, acquiring constraint information corresponding to the time series data, creating edited time series data by editing at least a part of the time series data, simulating the behavior of the water treatment plant based on the edited time series data and the time series data, calculating first simulation time series data that is a simulation result corresponding to the edited time series data, and second simulation time series data that is a simulation result corresponding to the time series data, and displaying the first simulation time series data, the second simulation time series data, and the constraint information. The processing circuit may be dedicated hardware, or may be a processor (also called a CPU, a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, or a DSP (Digital Signal Processor)) that executes a program stored in a memory.

[0052] When the processing circuit is a dedicated hardware, the processing circuit 20 corresponds to, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination of these, as shown in Fig. 8. Each function of the time series data acquisition unit 1, the constraint information acquisition unit 2, the time series data editing unit 3, the simulation execution unit 4, and the display control unit 5 may be realized by the processing circuit 20, or each function may be realized by one processing circuit 20.

[0053] When the processing circuit 20 is the processor 21 shown in FIG. 9, the functions of the time series data acquisition unit 1, the constraint information acquisition unit 2, the time series data editing unit 3, the simulation execution unit 4, and the display control unit 5 are realized by software, firmware, or a combination of software and firmware. The software or firmware is written as a program and stored in the memory 22. The processor 21 realizes each function by reading and executing the program recorded in the memory 22. That is, the operation support device includes a memory 22 for storing a program that results in the execution of a step of acquiring, as time series data, monitoring and control data collected from the water treatment plant by a monitoring control device that monitors the water treatment plant, a step of acquiring constraint information corresponding to the time series data, a step of editing at least a part of the time series data to create edited time series data, a step of simulating the behavior of the water treatment plant based on the edited time series data and the time series data, and a step of calculating first simulation time series data that is a simulation result corresponding to the edited time series data and second simulation time series data that is a simulation result corresponding to the time series data, and a step of controlling to display the first simulation time series data, the second simulation time series data, and the constraint information. It can also be said that these programs cause a computer to execute the procedures or methods of the time-series data acquisition unit 1, the constraint information acquisition unit 2, the time-series data editing unit 3, the simulation execution unit 4, and the display control unit 5. Here, the memory may be, for example, a non-volatile or volatile semiconductor memory such as a random access memory (RAM), a read-only memory (ROM), a flash memory, an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), a magnetic disk, a flexible disk, an optical disk, a compact disk, a digital versatile disk (DVD), or any storage medium to be used in the future.

[0054] In addition, with regard to each function of the time series data acquisition unit 1, the constraint information acquisition unit 2, the time series data editing unit 3, the simulation execution unit 4, and the display control unit 5, some functions may be realized by dedicated hardware and other functions may be realized by software or firmware.

[0055] Thus, the processing circuitry may implement the functions described above through hardware, software, firmware, or a combination of these.

[0056] <Driving assistance system> Fig. 10 is a block diagram showing the configuration of the driving support system. The driving support system is composed of a server 30 and a terminal device 31. The server 30 is a server installed on the cloud. The terminal device 31 is a device provided at a location where an operator is present. The server 30 and the terminal device 31 are connected to each other so as to be able to communicate with each other.

[0057] The server 30 includes a time series data acquiring unit 1, a constraint information acquiring unit 2, a time series data editing unit 3, a simulation executing unit 4, and a feature-added time series data recording unit 7. The terminal device 31 includes an input / output device 6. The components of the server 30 and the terminal device 31 are the same as the components of the driving support device according to the embodiment (see FIG. 2). Note that, although FIG. 10 illustrates an example of a configuration in which the time series data acquiring unit 1 acquires time series data from the feature-added time series data recording unit 7, the same configuration as that in FIG. 2 may be used.

[0058] 10 shows a configuration in which the components of the driving support device according to the embodiment are distributed to the server 30 and the terminal device 31, but the configuration of the driving support system is not limited to this. For example, the terminal device 31 may be configured to include either the time-series data editing unit 3 or the simulation execution unit 4, or both.
