Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in the maintenance and management of a water supply pipe network, work involving valve operation may be carried out. When the valve is operated and closed, water supply interruption occurs, so it is required to grasp the affected area due to the water supply interruption. Also, closing the valve may cause various other effects even without causing water supply interruption until then. For example, closing the valve may cause turbid water or a decrease in water pressure. Therefore, it is required to widely grasp the affected area due to the hydrological changes such as water supply interruption.

[0006] In contrast, while the ultrasonic flow control device described in Patent Document 1 detects water leakage based on the amount of water when a valve is opened and closed, Patent Document 1 does not specifically disclose how to analyze the range of influence caused by hydraulic changes when a valve is operated.

[0007] The objective of the present invention is to realize a water supply management information processing device that can broadly grasp the scope of influence caused by hydraulic changes when a valve is operated. [Means for solving the problem]

[0008] A water supply management information processing device according to one embodiment of the present invention is a device for processing information relating to water supply management. The water supply management information processing device includes a hydraulic analysis result related information acquisition unit that acquires hydraulic analysis result related information, which is information relating to the hydraulic analysis results of the pipeline when a valve operated during water supply construction is operated among the valves installed in the water supply pipeline, and an influence range estimation unit that estimates the influence range of the influence caused by hydraulic changes in the pipeline based on the hydraulic analysis result related information (first configuration).

[0009] In the above configuration, hydraulic analysis results-related information is acquired, and based on the acquired hydraulic analysis results-related information, the extent of the hydraulic influence that occurs in the pipeline when a valve operated during water supply construction is operated is estimated. The hydraulic analysis results-related information includes the results of hydraulic analysis that analyzes the flow or behavior of water, or the results of pipeline network analysis that analyzes the hydraulic conditions of the water distribution network.

[0010] There are various types of hydraulic changes caused by opening and closing valves. The aforementioned hydraulic analysis process can estimate, for example, whether closing the valve will cause a water outage, or whether turbid water will be generated due to changes in water pressure, flow velocity, or direction of water flow caused by closing the valve.

[0011] According to the above configuration, it is possible to provide a water supply management information processing device that can broadly grasp the scope of the effects caused by hydraulic changes when a valve is operated.

[0012] In the first configuration, the influence range estimation unit estimates the influence range for each type of hydraulic change (second configuration).

[0013] In the configuration described above, the impact range estimation unit estimates the range of impact caused by each type of change. The types of changes include, for example, changes that have a direct impact by operating a valve, and changes that have an indirect impact. Direct impacts include, for example, the occurrence of water outages. Indirect impacts include, for example, the occurrence of turbid water or a decrease in water pressure. The range of direct impacts and the range of indirect impacts do not necessarily coincide because their causes are different.

[0014] According to the above configuration, these types of changes can be distinguished and estimated. This allows for more accurate estimations that correspond to the different scope of impact for each type.

[0015] In the first configuration, the system further includes: a hydraulic analysis execution unit that creates at least one candidate valve operation pattern for the valve to be operated based on the work plan for the waterworks construction and performs hydraulic analysis based on the created candidate valve operation pattern; a first pattern determination unit that determines a first pattern of the valve to be operated from the candidate valve operation pattern based on the results of the hydraulic analysis; a field survey information acquisition unit that acquires field survey information that investigates items related to the waterworks construction in the construction area that is the target of the waterworks construction in which the valve is operated with the first pattern; and a second pattern creation unit that creates a second pattern by changing at least some of the valves included in the first pattern based on the field survey information. The hydraulic analysis result related information acquisition unit acquires the hydraulic analysis result related information when the valve is operated with the second pattern (third configuration).

[0016] In the configuration described above, the first pattern of valves to be operated is determined based on the results of hydraulic analysis performed using previously accumulated data, rather than on-site survey information.

[0017] The data accumulated in the past may differ from the current situation in the construction area. For example, a valve that has not been operated for many years may be unoperable.

[0018] Therefore, in the above configuration, a second pattern is created by making changes to the first pattern based on on-site survey information. In the above configuration, for example, inoperable valves are excluded from the second pattern, and operable valves are included in the second pattern.

[0019] According to the above configuration, by using hydraulic analysis results based on on-site survey information, the scope of impact can be estimated more accurately in accordance with the current situation.

[0020] In the third configuration, the field survey information acquisition unit acquires the field survey information, including information regarding the use of roads or facilities located in the construction area. The system further includes a notification plan creation unit that creates a notification plan, which is a notification plan for the construction target area, based on the aforementioned on-site survey information and the aforementioned hydraulic changes (fourth configuration).

[0021] In the above configuration, the on-site survey information includes information on the use of roads or facilities located within the construction area targeted by the water supply construction. Information on use includes usage status or available hours. Usage status includes, for example, frequency of use. Usage status includes, for example, road traffic volume by time of day. Available hours include, for example, the business hours of a facility such as a shop.

[0022] According to the above configuration, a more accurate notification plan can be created based on on-site survey information, including information on the use of such roads or facilities.

[0023] The fourth configuration further includes a notification unit that notifies the persons to be notified in the construction area in accordance with the notification plan (fifth configuration).

[0024] In the above configuration, appropriate notification can be performed for the notification target person based on the notification plan.

[0025] In any one of the first to fifth configurations, it further has a work progress information acquisition unit that acquires progress information regarding the work progress of the water pipe construction. The notification plan creation unit corrects the notification plan based on the progress information (sixth configuration).

[0026] In the above configuration, the notification plan can be corrected according to the work progress of the water pipe construction. According to the above configuration, even when an unexpected situation occurs at the construction site, the notification plan can be corrected according to the situation.

[0027] A water pipe management information processing system according to an embodiment of the present invention includes a server device and a first computing terminal capable of communicating with the server device, and is a system for processing information related to water pipe management. The server device includes a hydraulic analysis result-related information acquisition unit that acquires hydraulic analysis result-related information, which is information related to the hydraulic analysis result of the pipeline when operating a valve provided in the pipeline of the water pipe during the construction of the water pipe; an influence range estimation unit that estimates the influence range of the influence caused by the hydraulic change in the pipeline based on the hydraulic analysis result-related information; and an output unit that outputs the influence range to the first computing terminal (seventh configuration).

[0028] In the above configuration, the server device acquires hydraulic analysis result-related information and estimates the influence range of the influence caused by the hydraulic change in the pipeline based on the acquired hydraulic analysis result-related information.

[0029] According to the above configuration, a water pipe management information processing system that can widely grasp the influence range of the influence caused by the hydraulic change when the valve is operated can be provided.

[0030] In the seventh configuration, the system further includes a second computing terminal capable of communicating with the server device. The server device further includes: a hydraulic analysis execution unit that creates at least one candidate operating valve pattern for a valve to be operated based on the work plan for the waterworks construction and performs hydraulic analysis based on the created candidate operating valve pattern; a first pattern determination unit that determines a first pattern of the valve to be operated from the candidate operating valve pattern based on the results of the hydraulic analysis; and a second pattern creation unit that creates a second pattern by changing at least some of the valves included in the first pattern based on on-site survey information that investigates items related to the waterworks construction. The second computing terminal has an on-site survey information output unit that outputs on-site survey information that investigates items related to the waterworks construction in the construction area that is the target of the waterworks construction in which the valve is operated in the first pattern to the server device; the second pattern creation unit of the server device creates the second pattern based on the on-site survey information output by the second computing terminal; and the hydraulic analysis result related information acquisition unit of the server device acquires the hydraulic analysis result related information when the valve is operated in the second pattern (eighth configuration).

[0031] In the configuration described above, the server device determines the first pattern of valves to operate based on the results of hydraulic analysis performed using previously accumulated data, rather than relying on on-site survey information.

[0032] The data accumulated in the past may differ from the current situation in the construction area. For example, a valve that has not been operated for many years may be unoperable.

[0033] Therefore, in the above configuration, the server device creates the second pattern by making changes to the first pattern based on the field survey information output by the second computing terminal. In the above configuration, for example, valves that cannot be operated are excluded from the second pattern, and valves that can be operated are included in the second pattern.

[0034] According to the above configuration, a water supply management information processing system can be realized that can perform more accurate estimations tailored to the current situation using hydraulic analysis results based on on-site survey information.

[0035] In the eighth configuration, the field survey information output unit of the second computing terminal outputs the field survey information, which includes information regarding the use of roads or facilities located in the construction area. The server device further includes a notification plan creation unit that creates a notification plan, which is a notification plan for the construction area, based on the field survey information and the hydraulic changes (ninth configuration).

[0036] According to the above configuration, a water management information processing system can be realized that can create a more realistic notification plan based on on-site survey information, including information on the use of roads or facilities.

[0037] In any one of the seventh to ninth configurations, the system further includes a third computing terminal capable of communicating with the server device. The third computing terminal has a progress information output unit that outputs progress information, which is information relating to the progress of the waterworks construction work, to the server device. The notification plan creation unit of the server device modifies the notification plan based on the progress information output by the third computing terminal (tenth configuration).

[0038] With the above configuration, the notification plan can be modified according to the progress of the waterworks construction. According to the above configuration, even if an unexpected situation occurs at the construction site, the notification plan can be modified according to the situation.

[0039] A water supply management information processing method according to one embodiment of the present invention is a method for processing information relating to water supply management. The water supply management information processing method includes a hydraulic analysis result related information acquisition step, which is information relating to the hydraulic analysis results of the pipeline when a valve operated during water supply construction is operated among the valves installed in the water supply pipeline, and a change estimation step, which estimates hydraulic changes in the pipeline based on the hydraulic analysis result related information (11th configuration).

[0040] In the configuration described above, hydraulic analysis results-related information is acquired, and based on the acquired hydraulic analysis results-related information, the affected area of ​​the impact caused by hydraulic changes in the pipeline is estimated.

[0041] According to the above configuration, a water supply management information processing method can be provided that can broadly grasp the scope of influence caused by hydraulic changes when a valve is operated.

[0042] A water supply management information processing program according to one embodiment of the present invention is a program that processes information related to water supply management. The water supply management information processing program causes a computer to perform a hydraulic analysis result related information acquisition step, which is information related to the hydraulic analysis results of the pipeline when a valve operated during water supply construction is operated among the valves installed in the water supply pipeline, and a change estimation step, which estimates hydraulic changes in the pipeline based on the hydraulic analysis result related information (12th configuration).

[0043] In the configuration described above, hydraulic analysis results-related information is acquired, and based on the acquired hydraulic analysis results-related information, the affected area of ​​the impact caused by hydraulic changes in the pipeline is estimated.

[0044] According to the above configuration, it is possible to provide a water supply management information processing program that can broadly grasp the scope of the effects caused by hydraulic changes when a valve is operated. [Effects of the Invention]

[0049] This allows for a broader understanding of the impact of hydraulic changes resulting from valve operation. [Brief explanation of the drawing]

[0051] The following describes each embodiment with reference to the drawings. In each drawing, the same parts are denoted by the same reference numerals, and the description of those parts will not be repeated. Note that the dimensions of the components in each drawing do not faithfully represent the dimensions of the actual components or the dimensional ratios of each component.

[0052] [Embodiment 1] Figure 1 is a functional block diagram showing the schematic configuration of a water supply management information processing device 1 according to Embodiment 1 of the present invention. Referring to Figure 1, the water supply management information processing device 1 is a device that processes information related to water supply management. The water supply management information processing device 1 also performs information processing to support maintenance and management operations of pipelines, for example.

[0053] The water management information processing device 1 can be implemented, for example, by a computer having a processor and memory for storing programs executed by the processor or various types of data. In the water management information processing device 1, the processor and the memory may be integrated on a single chip. The water management information processing device 1 may be a single device or may consist of one or more server devices. The water management information processing device 1 may have a communication connection function that allows it to communicate with an external communication terminal.

[0054] The water supply management information processing device 1 includes a hydraulic analysis result related information acquisition unit 11 and an influence range estimation unit 12.

[0055] The hydraulic analysis result related information acquisition unit 11 acquires hydraulic analysis result related information D11, which is information related to the hydraulic analysis results of the pipeline when a valve operated during the construction of the water pipeline is operated among the valves installed in the water pipeline.

[0056] The influence range estimation unit 12 estimates the influence range of the effects caused by hydraulic changes in the pipeline based on the hydraulic analysis result related information D11 acquired by the hydraulic analysis result related information acquisition unit 11. The influence range estimation unit 12 outputs influence range information D12 related to the estimated influence range.

[0057] (Water supply management information processing method) Figure 2 shows the state of the pipelines in Block K before the water outage. Figure 3 shows the state of the pipelines in Block K during the water outage. Referring to Figures 1, 2, and 3, the method for processing water management information when water outages are carried out in Block K for water supply construction will be explained.

[0058] First, referring to Figure 2, the water pipe network PN1, which is subject to maintenance, is composed of pipes PP11-PP18 connected to each other. Pipes PP11-PP13 are interconnected at one end. Valve VL11 is installed at the other end of pipe PP11. Valve VL12 is installed at the other end of pipe PP12.

[0059] The other end of pipe PP13 is connected to one end of pipe PP14. Valve VL13 is installed between the other end of pipe PP13 and one end of pipe PP14.

[0060] The other end of pipe PP14 is connected to one end of pipe PP15. Valve VL14 is installed between the other end of pipe PP14 and one end of pipe PP15.

[0061] Pipelines PP15 and PP17 are interconnected at their other ends. Valve VL15 is installed at one end of pipeline PP16. Valve VL16 is installed at one end of pipeline PP17. Pipeline PP18 is connected to one end of pipeline PP16 via valve VL15.

[0062] Additionally, pipelines PP11-PP13 are buried under road STR11. Pipelines PP15-PP118 are buried under road STR12. Pipeline PP14 is buried under road STR13, which connects roads STR11 and STR12.

[0063] Building BLD1 is located facing road STR11. Water is supplied to building BLD1 from pipeline PP11 via a water supply pipe. Buildings BLD2 and BLD3 are located facing road STR12. Water is supplied to building BLD2 from pipeline PP17 via a water supply pipe. In addition, water is supplied to building BLD3 from pipeline PP18 via a water supply pipe.

[0064] When carrying out renewal or repair work on pipeline PP14 buried in road STR13, which is designated as target WK1, valves around pipeline PP14, which is the target WK1, must be operated to close them in order to shut off the water supply. The pattern of valves to be closed can be considered from multiple perspectives based on hydraulic changes in the pipeline to be shut off and pipelines located around the target pipeline, the impact on surrounding facilities, and the efficiency of the construction work. Under various conditions, the pipeline to be shut off may include not only pipeline PP14, which is the target WK1, but also other pipelines. For example, the valve that was intended to be operated may be inoperable, in which case it is necessary to operate a different valve.

[0065] Next, referring to Figure 3, an example of carrying out construction work in the construction area TA1 with the water supply cut off by closing valves VL11, VL12, and VL14 is described below.

[0066] In the construction area TA1, the water supply is shut off by operating a valve. The construction area TA1 refers to the area targeted by the water supply construction where the valve is operated. The construction area TA1 may include pipelines where the hydraulics change, facilities supplied with water from the pipelines where the hydraulics change, or roads related to the construction. The pipelines subject to the water shutoff are pipelines PP11, PP12, PP13, and PP14, which are shown by diagonal lines in Figure 3. Referring also to Figure 1, in the water supply management information processing method, first, the hydraulic analysis result related information acquisition unit 11 acquires hydraulic analysis result related information D11 for the water supply network PN1 when valves VL11, VL12, and VL14 are operated (hydraulic analysis result related information acquisition step).

[0067] Hydraulic analysis results related information D11 includes the results of hydraulic analyses that analyze water flow or behavior, or the results of pipe network analyses that analyze the hydraulic conditions of the water distribution network.

[0068] The hydraulic analysis result-related information acquisition unit 11 may acquire hydraulic analysis result-related information D11 from an external system via a communication network. Alternatively, the water supply management information processing device 1 may perform hydraulic analysis and generate hydraulic analysis result-related information D11. The hydraulic analysis may be performed on a predetermined range of pipelines affected by the construction work. For example, the hydraulic analysis may be performed on the same water distribution area as the pipeline PP14 which is the target WK1.

[0069] A water distribution area refers to the area to which water is supplied from a water source. A water source refers to a water treatment plant, reservoir, or water tower, etc. There may be one or more water sources. Multiple water distribution areas may belong to a single water distribution area group. A water distribution area may be divided into multiple water distribution blocks. Water distribution blocks may be further divided into sub-blocks, and sub-blocks may be further divided into small blocks, and so on, creating a hierarchical division.

[0070] The hydraulic analysis result-related information D11 includes, for example, analysis result ANL1 indicating that no water is flowing and there is a water outage in pipelines PP11, PP12, PP13, and PP14. The hydraulic analysis result-related information D11 also includes, for example, analysis result ANL2 indicating that water is flowing in pipelines PP16, PP17, and PP18. Analysis results ANL1 and ANL2 may include water pressure distribution, flow direction, or flow velocity, etc. Note that in analysis result ANL1, the water pressure and flow velocity are zero or lower than normal.

[0071] Next, the influence area estimation unit 12 estimates the influence area based on the hydraulic analysis result-related information D11 acquired by the hydraulic analysis result-related information acquisition unit 11 (influence area estimation step).

[0072] The scope of impact includes, for example, direct effects resulting from operating a valve, and indirect effects related to those direct effects. Direct effects include, for example, water outages. Indirect effects include, for example, turbid water or a decrease in water pressure. The scope of impact where direct effects occur and the scope of impact where indirect effects occur do not necessarily coincide because their causes are different.

[0073] For example, the direct effects are as follows: Building BLD1, which is supplied with water from pipeline PP11, the pipeline subject to the water outage, will have its water supply cut off as a result of the water outage. In addition, for example, the indirect effects are as follows: Closing valve VL14 may cause changes in water pressure or flow velocity during the water outage. Therefore, for example, turbid water may be generated in the area downstream of valve VL14 (the area shown by the diagonal checkered pattern in Figure 3). Consequently, building BLD3 may not be directly affected by the water outage, but may be indirectly affected by the turbid water.

[0074] Furthermore, if roads STR11 and STR13 are used in the construction of pipeline PP14, which is the target WK1, then roads STR11 and STR13 will be included in the construction area TA1. Roads STR11 and STR13, which are included in the construction area TA1, will be closed to traffic during the construction. Therefore, for example, water outages will affect the use of building BLD1 and roads STR11 and STR13.

[0075] Thus, in order to carry out construction work on pipeline PP14, which is the target WK1, not only will pipeline PP14 and the surrounding pipelines be shut off, but the roads near where pipeline PP14 is buried will also be closed to traffic. The construction area TA1, which is the target of the water supply work that involves operating the valves, includes not only pipeline PP14, which is the target WK1, but also pipelines PP11, PP12, and PP13. In addition, in Figure 3, roads STR11 and STR13, which are included in the construction area TA1, are shown in shaded areas.

[0076] The impact area estimation unit 12 outputs impact area information D12 indicating that the building BLD1 and roads STR11 and STR13 are included in the direct impact area of ​​the water outage.

[0077] On the other hand, building BLD2, which is supplied with water from pipeline PP17, which is not subject to the water outage, is not particularly affected by the water outage. Also, road STR12 is not closed to traffic due to the aforementioned water outage, so road STR12 is also not affected by the water outage. The impact information D12 may include information indicating that building BLD2 and road STR12 are not affected.

[0078] Furthermore, as mentioned above, Building BLD3 may be indirectly affected by turbid water, even if it is not directly affected by the water outage. Therefore, the impact information D12 may include information indicating that Building BLD3 is indirectly affected.

[0079] As described above, the water supply management information processing device 1 acquires hydraulic analysis result-related information D11 and estimates the range of influence caused by hydraulic changes in the pipeline when a valve operated during water supply construction is operated, based on the acquired hydraulic analysis result-related information D11.

[0080] According to the above configuration, a water supply management information processing device 1 and a water supply management information processing method can be realized that can broadly grasp the scope of influence caused by hydraulic changes when a valve is operated.

[0081] (Water supply management information processing program) A water supply information management program that causes the computer of the water supply information processing device 1 to process information related to water supply management also falls within the scope of the present invention. A water supply information management program according to one embodiment of the present invention causes a computer to perform a hydraulic analysis result related information acquisition step, which is information related to the hydraulic analysis results of the water supply pipeline when a valve operated during water supply construction is operated among the valves installed in the water supply pipeline, and an influence range estimation step, which estimates the influence range of the influence caused by hydraulic changes in the pipeline based on the hydraulic analysis result related information.

[0082] According to the above configuration, a water supply information management program can be realized that can broadly grasp the scope of the effects caused by hydraulic changes when a valve is operated.

[0083] [Embodiment 2] Figure 4 is a functional block diagram showing the schematic configuration of the water supply management information processing system SYS2 according to Embodiment 2 of the present invention. The water supply management information processing system SYS2 differs from the water supply management information processing device 1 according to Embodiment 1 in that the pattern of valves to be operated is determined based on on-site survey information. In the following description, components similar to those in Embodiment 1 are denoted by the same reference numerals and their description is omitted.

[0084] (Water supply management information processing system) The SYS2 water supply management information processing system is a system for managing information related to the maintenance and management of water supply. Referring to Figure 4, the SYS2 water supply management information processing system comprises a server device 10, a first processing terminal 50, and a second processing terminal 60. The server device 10, the first processing terminal 50, and the second processing terminal 60 are configured to communicate with each other via a communication network.

[0085] (First computing terminal) The first computing terminal 50 is a stationary or mobile computer device. The first computing terminal 50 may be, for example, a terminal used by headquarters staff who perform pipeline maintenance work. The first computing terminal 50 has, although not specifically shown in the figures, an input device for receiving user input, an output device for displaying information, a processor, and memory.

[0086] (Server device) The server device 10 is a computer device having a processor and memory. The server device 10 can be composed of one or more computer devices. The server device 10 includes a storage unit 20, a hydraulic analysis execution unit 31, a first pattern determination unit 32, a second pattern creation unit 33, a hydraulic analysis result related information acquisition unit 34, an influence range estimation unit 35, an influence range output unit 36, a notification plan creation unit 37, and a notification unit 38.

[0087] (Storage part) The memory unit 20 is, for example, a storage device such as a hard disk, flash memory, or main memory. The memory unit 20 stores work plan information D21, pipeline information D22, hydraulic analysis result-related information D23, and operating valve pattern candidates D30.

[0088] Work plan information D21 is information regarding the planning of work in water supply construction. Work plan information D21 includes information about the construction area, information about the pipeline to be constructed, work details, construction company, and construction schedule.

[0089] Pipeline information D22 includes information about water supply pipelines. Pipeline information D22 may include, for example, a pipeline ID for identifying pipelines in water supply maintenance or hydraulic analysis. Pipeline information D22 may include location information where the pipeline is located. Pipeline information D22 may include information about nodes such as branching, merging, connecting, or termination of the pipeline. A pipeline may be composed of multiple pipe materials connected together. Therefore, pipeline information D22 may include pipe material IDs for identifying the multiple pipe materials that make up the pipeline. Pipeline information D22 may include information about the degree of deterioration of the pipeline. Pipeline information D22 may include, for example, information such as the date of installation of the pipeline, the material of the pipe materials that make up the pipeline, or the shape of the pipe materials.

[0090] The pipeline information D22 may include equipment management information relating to equipment placed in the pipeline. This equipment may include pumps, faucets, valves, or various sensors used for maintenance. In the following, the pipeline and equipment together will be referred to as the piping system.

[0091] The hydraulic analysis results related information D23 includes information regarding the hydraulic analysis results of the pipeline. The pipeline information D22 and the hydraulic analysis results related information D23 may be linked to each other. The information regarding the hydraulic analysis results includes the distribution of water pressure, flow direction, or flow velocity in each pipeline. The information regarding the hydraulic analysis results also includes the results of the deterioration assessment of the pipeline network.

[0092] Furthermore, hydraulic analysis result-related information D23 is generated for each candidate operating valve pattern D30 and linked to each other. In the following, specific hydraulic analysis result-related information from hydraulic analysis result-related information D23 is represented by the symbol D231. Hydraulic analysis result-related information D231 is information related to the hydraulic analysis results of the pipeline when the valve installed in the water pipeline is operated using the second pattern D32 described later.

[0093] The proposed operating valve pattern D30 includes a pattern of valves to be operated to shut off the water supply to a pipeline when performing construction work on that pipeline. One operating valve pattern consists of a combination of multiple valves. Proposed operating valve pattern D30 includes, for example, a first pattern D31 and a second pattern D32. Details of the first pattern D31 and the second pattern D32 will be described later.

[0094] (Hydraulic Analysis Execution Unit) The hydraulic analysis execution unit 31 creates at least one candidate valve operation pattern D30 for the valves to be operated based on the work plan for the water supply construction, and performs a hydraulic analysis based on the created candidate valve operation pattern D30. The candidate valve operation pattern D30 may or may not specify the order in which the valves are operated. The hydraulic analysis by the hydraulic analysis execution unit 31 is performed, for example, in response to a request from the first computing terminal 50.

[0095] (First pattern determination section) The first pattern determination unit 32 determines the first pattern D31 of the valve to be operated from the candidate operating valve pattern D30 based on the results of the hydraulic analysis. The first pattern determination unit 32 outputs the on-site survey request D13, which includes items related to the water supply construction, to the second calculation terminal 60, which will be described later.

[0096] (Second pattern creation section) The second pattern creation unit 33 creates a second pattern D32 by changing at least some of the valves included in the first pattern D31, based on the field survey information D61 which investigates items related to the water supply construction. Furthermore, the second pattern creation unit 33 may create a second pattern D32 by changing some of the valves included in the first pattern D31, or it may create a second pattern D32 by changing all of the valves included in the first pattern D31. The field survey information D61 is input to the second pattern creation unit 33 by the second processing terminal 60, which will be described later.

[0097] (Hydraulic analysis results related information acquisition unit) The hydraulic analysis result related information acquisition unit 34 acquires hydraulic analysis result related information D231 when the valve is operated in the second pattern D32. The hydraulic analysis result related information acquisition unit 34 may further acquire work plan information D21. The hydraulic analysis result related information acquisition unit 34 outputs the hydraulic analysis result related information D231 and the work plan information D21 to the influence range estimation unit 35.

[0098] (Estimation of scope of influence) The influence range estimation unit 35 estimates the influence range D121 of the effects caused by hydraulic changes in the pipeline based on the hydraulic analysis result related information D231. The influence range estimation unit 35 estimates the influence range D121 for each type of hydraulic change.

[0099] The types of changes include, for example, changes that have a direct effect as a result of operating a valve, and changes that have an indirect effect. As mentioned above, direct effects include, for example, the occurrence of water outages. Also, as mentioned above, indirect effects include the occurrence of turbid water or a decrease in water pressure. The scope of effects where direct effects occur and the scope of effects where indirect effects occur do not necessarily coincide because their causes are different.

[0100] According to the above configuration, it is possible to distinguish between these types of changes and estimate the affected area D121. This allows for more accurate estimations that correspond to the different ranges of change for each type.

[0101] (Affected area output section) The influence range output unit 36 ​​outputs influence range information D12 related to influence range D121 to the first processing terminal 50.

[0102] (Hochi Planning Department) The notification planning unit 37 creates a notification plan D15, which is a notification plan for the construction target area, based on the on-site survey information D61 and the estimated impact area D121.

[0103] The notification planning unit 37 creates a notification plan D15, which includes, for example, the means of notification, the recipient of the notification, the timing of the notification, and the content of the notification. Examples of means of notification include email, SNS (Social Networking Service), messaging services, web pages, digital signage, written documents, posters, or visits by notification personnel.

[0104] The timing of the notification may be before, during, or after the construction period, depending on the content of the notification.

[0105] The notification will include information such as the type of hydraulic change. As mentioned above, the type of hydraulic change will include whether it is a direct effect such as water outage, or an indirect effect such as turbid water or a decrease in water pressure. The notification will also include the date and time of the impact, and whether roads will be usable.

[0106] According to the Information Planning Department 37, a more accurate information planning plan D15 can be created based on on-site survey information D61, which includes information on the use of roads or facilities.

[0107] (News Department) The notification unit 38 notifies the persons to be notified in the construction area via email or other means in accordance with notification plan D15. According to the notification unit 38, appropriate notifications can be made to the persons to be notified based on notification plan D15.

[0108] The server device 10 may also be a support server for creating work plans in pipeline maintenance operations.

[0109] (Second computing terminal) The second computing terminal 60 is, for example, a mobile computer device such as a smartphone. The second computing terminal 60 may also be, for example, a terminal used by field workers performing pipeline maintenance work. The second computing terminal 60, although not specifically shown in the figures, has an input device for receiving user input, an output device for displaying information, a processor, and memory.

[0110] The second computing terminal 60 has a field survey information output unit 61.

[0111] The field survey information output unit 61 outputs the field survey information D61 to the server device 10. The field survey information D61 includes the results of an investigation into items related to the waterworks construction in the construction area that is the target of the waterworks construction in which the valve is operated in the first pattern D31.

[0112] For example, field survey information D61 includes information on the use of roads or facilities located within the construction area targeted by the water supply construction. Information on use includes usage status or available hours. Usage status includes, for example, frequency of use. Usage status includes, for example, traffic conditions such as road traffic volume by time of day. Available hours include, for example, the business hours of a store as a facility.

[0113] (Water management information processing by the water management information processing system) Figure 5 is a flowchart showing the flow of water supply information management processing in the SYS2 water supply management information processing system. Figure 6 is a diagram showing the state of the pipeline during a water outage when the valve is closed in a different pattern than in Figure 3.

[0114] Referring to Figures 5 and 6, as well as Figures 3 and 4, first, the first computing terminal 50 requests the server device 10 to create candidate operating valve patterns and perform hydraulic analysis (step S501). Then, the hydraulic analysis execution unit 31 of the server device 10 performs hydraulic analysis for each candidate operating valve pattern D30 (step S101).

[0115] Next, the first pattern determination unit 32 of the server device 10 determines the first pattern D31 of the valve to be operated from the candidate operating valve pattern D30 based on the results of the hydraulic analysis (step S102). The first pattern determination unit 32 may, for example, determine the first pattern D31 from among the feasible candidate operating valve pattern D30 such that the water supply interruption range is smallest. For example, as already explained with reference to Figure 3, the first pattern determination unit 32 determines a pattern that closes valves VL11, VL12, and VL14 as the first pattern.

[0116] Next, the first pattern determination unit 32 transmits a field survey request D13 to the second calculation terminal 60 (step S103). The field survey request D13 includes, as survey items, information regarding the operation of valves located in the construction target area, and information regarding the use of roads and facilities located in the construction target area. In addition, the field survey request D13 specifies Block K as the survey area. The survey area may include all locations related to the candidate operating valve pattern D30. For example, within the survey area, all of valves VL11, VL12, VL13, VL14, VL15, and VL16 in Figure 3 may be subject to confirmation of their operation status.

[0117] The first pattern determination unit 32 may transmit not only the field survey request D13, but also at least one of the following to the second calculation terminal 60: work plan information D21, pipeline information D22, hydraulic analysis result-related information D23, or operating valve pattern candidate D30. Alternatively, the second calculation terminal 60 may download at least one of the following from the server device 10: field survey request D13, work plan information D21, pipeline information D22, hydraulic analysis result-related information D23, or operating valve pattern candidate D30.

[0118] Next, the survey results are entered into the second computing terminal 60 by the field worker. For example, if valve VL14 shown in Figure 3 is actually inoperable, the information regarding the inoperability of valves located in the construction area will be updated to indicate that valve VL14 is inoperable.

[0119] As information regarding the use of roads located within the aforementioned construction area, traffic conditions such as traffic volume on roads STR11, STR12, and STR13 during each time period may be entered.

[0120] Furthermore, the operating hours of buildings BLD1 and BLD2 are entered as information regarding the use of facilities located in the aforementioned construction area. The operating hours of buildings BLD1 and BLD2 may, for example, be the hours during which water supply is available within buildings BLD1 and BLD2. The operating hours of buildings BLD1 and BLD2 may, for example, be the operating hours of restaurants or other shops operating within buildings BLD1 and BLD2. Also, if buildings BLD1 and BLD2 are offices, the operating hours may be the working hours of the employees working in the offices, or the hours during which the entrances to buildings BLD1 and BLD2 are unlocked.

[0121] Furthermore, the results of on-site inspections of measuring instruments placed in the pipeline may be entered as part of the investigation results. In addition, the diameter of the pipeline or other information about the pipeline confirmed on-site may be entered as part of the investigation results.

[0122] The field survey information output unit 61 of the second computing terminal 60 generates field survey information D61 according to the input content (step S601). The field survey information output unit 61 of the second computing terminal 60 transmits the generated field survey information D61 to the server device 10 (step S602).

[0123] Next, the second pattern creation unit 33 of the server device 10 creates a second pattern D32 by changing at least some of the valves included in the first pattern D31, based on the field survey information D61 output by the second computing terminal 60 (step S104).

[0124] In the example shown in Figure 3, if valve VL14 is inoperable, the second pattern generation unit 33 considers patterns obtained by operating other valves as candidates. For example, as shown in Figure 6, in the first pattern D31 shown in Figure 3, by further closing the operable valves VL15 and VL16, the pipeline PP14 which is the target WK1 can be made to a water-off state (shown as a vertical and horizontal checkered pattern in Figure 6).

[0125] The second pattern creation unit 33 creates a second pattern by changing valves VL11, VL12, and VL14 included in the first pattern D31 shown in Figure 3 to valves VL11, VL12, VL15, and VL16, as shown in Figure 6. The second pattern may be selected from the patterns included in the operating valve pattern candidate D30, or a new pattern not included in the operating valve pattern candidate D30 may be created.

[0126] Next, the hydraulic analysis execution unit 31 performs a hydraulic analysis when the valve is operated using the second pattern D32. If the second pattern D32 is included in the candidate valve operation pattern D30 and hydraulic analysis result related information D23 has already been generated linked to the second pattern D32, the hydraulic analysis execution unit 31 may omit the above hydraulic analysis.

[0127] As shown in Figure 6, when the valve is operated in the second pattern D32, the construction area TA2 includes pipelines PP11-PP17 and roads STR11, STR12, and STR13.

[0128] The hydraulic analysis result related information acquisition unit 34 acquires hydraulic analysis result related information D23 when the valve is operated in the second pattern D32. Furthermore, the influence range estimation unit 35 estimates the influence range D121 of the influence caused by the hydraulic changes in the pipeline based on the acquired hydraulic analysis result related information D23 (step S105).

[0129] The affected area D121 includes buildings BLD1 and BLD2, and roads STR11, STR12, and STR13.

[0130] Furthermore, the influence range estimation unit 35 estimates the influence range D121 for each type of hydraulic change. For example, the influence range of a water outage, which is a direct effect, includes buildings BLD1 and BLD2. Also, even if the water outage does not occur in pipeline PP18 due to the closing of valve VL15, it may be affected by turbid water or a drop in water pressure during a water outage. For this reason, building BLD3 is included in the influence range of turbid water and a drop in water pressure, which are indirect effects of a water outage. In addition, turbidity may occur in pipelines PP15-PP17 due to changes in flow velocity or water pressure during water outages and interruptions. If hydraulic analysis estimates that such turbid water will occur in pipelines PP15-PP17, the influence range estimation unit 35 includes buildings BLD1, BLD2, and BLD3, which face pipeline PP17, in the influence range of turbid water, which is an indirect effect.

[0131] Furthermore, changes in flow velocity or water pressure may occur in pipelines other than those experiencing a water outage. For this reason, the influence range estimation unit 35 may include pipelines other than those experiencing a water outage in the influence range, which is the range of indirectly affected turbid water.

[0132] Next, the notification plan creation unit 37 creates a notification plan, which is a notification plan for the construction area, based on the on-site survey information D61 and the affected area D121 (step S106). The notification plan creation unit 37 creates a notification plan based, for example, on information regarding the use of facilities located in the construction area. Figure 7 shows an example of creating a notification plan D15 based on information regarding the use of facilities located in the construction area.

[0133] Referring further to Figure 7, the field survey information D61 includes the business hours of store A, located in building BLD1, and store B, located in building BLD2, both of which are included in the affected area D121. Store A opens at 9:00, and store B opens at 11:00. In addition, the work plan information D21 includes the construction schedule. The construction schedule is until 10:00 on XX / XX / 20XX. The construction schedule overlaps with the business hours of store A.

[0134] Therefore, the notification plan creation unit 37 decides, for example, to notify the manager of building BLD1 or store A before the start of construction, while not notifying the manager of building BLD2 or store B. The notification plan creation unit 37 then creates a notification plan D15, for example, to notify the manager of building BLD1 or store A by email before the start of construction.

[0135] Next, the first computing terminal 50 receives the estimated impact area D121 and notification plan D15 from the server device 10 (step S502).

[0136] Next, the headquarters staff confirms the notification plan D15 on the first computing terminal 50. The first computing terminal 50 may modify the notification plan D15 in response to the headquarters staff's operation. When the first computing terminal 50 sends a notification request to the server device 10 (step S503), the server device 10 issues a notification via the notification unit 38 (step S107).

[0137] In the configuration described above, the first valve pattern D31 to be operated is determined based on the results of a hydraulic analysis performed using previously accumulated data, rather than relying on on-site survey information D61.

[0138] The data accumulated in the past may differ from the current situation in the construction area. For example, as mentioned above, a valve that has not been operated for many years may be unoperable.

[0139] Therefore, in the above configuration, the second pattern D32 is created by making changes to the first pattern D31 based on the field survey information D61. In the above configuration, for example, valves that cannot be operated are excluded from the second pattern D32, and valves that can be operated are included in the second pattern D32.

[0140] According to the above configuration, by using the hydraulic analysis results based on field survey information D61, the affected area D121 can be estimated more accurately in accordance with the current situation.

[0141] As described above, the water supply management information processing system SYS2 is a system that processes information related to water supply management. The water supply management information processing system SYS2 has a server device 10 and a first computing terminal 50 that can communicate with the server device 10. The server device 10 has a hydraulic analysis result related information acquisition unit 34 that acquires hydraulic analysis result related information D23, which is information related to the hydraulic analysis results of the pipeline when a valve operated during water supply construction is operated among the valves installed in the water supply pipeline; an influence range estimation unit 35 that estimates the influence range D121 of the influence caused by hydraulic changes in the pipeline based on the hydraulic analysis result related information D23; and an influence range output unit 36 ​​that outputs influence range information D12 related to the influence range D121 to the first computing terminal 50.

[0142] According to the above configuration, a water supply management information processing system SYS2 can be realized that can provide estimation results that allow for a broad understanding of the influence range D121 caused by hydraulic changes when a valve is operated.

[0143] [Embodiment 3] Figure 8 is a functional block diagram showing the schematic configuration of the water supply management information processing system SYS3 according to Embodiment 3 of the present invention. The water supply management information processing system SYS3 differs from the water supply management information processing system SYS2 in Embodiment 2 in that it modifies the notification plan based on the progress of water supply construction work. In the following description, components similar to those in Embodiment 2 are denoted by the same reference numerals and their description is omitted.

[0144] (Water supply management information processing system) The SYS3 water supply management information processing system is a system for managing information related to the maintenance and management of water supply. Referring to Figure 8, the SYS3 water supply management information processing system includes a server device 10, a first processing terminal 50, a second processing terminal 60, and a third processing terminal 70. The server device 10, the first processing terminal 50, the second processing terminal 60, and the third processing terminal 70 are configured to communicate with each other via a communication network.

[0145] (Third computing terminal) The third computing terminal 70 is, for example, a mobile computer device such as a smartphone. The third computing terminal 70 may also be, for example, a terminal used by a field worker performing maintenance work on pipelines. The field worker may be a worker performing waterworks construction in the construction area. The third computing terminal 70 has, although not specifically shown in the figures, an input device for receiving user input, an output device for displaying information, a processor, and memory.

[0146] The third computing terminal 70 has a progress information output unit 71. The progress information output unit 71 outputs progress information D71, which is information relating to the progress of the waterworks construction work, to the server device 10. For example, the third computing terminal 70 creates progress information D71 in response to input operations from the field workers.

[0147] (Server device) The server device 10 includes a storage unit 20, a hydraulic analysis execution unit 31, a first pattern determination unit 32, a second pattern creation unit 33, a hydraulic analysis result related information acquisition unit 34, an influence range estimation unit 35, an influence range output unit 36, a notification plan creation unit 39, and a notification unit 38.

[0148] (Hochi Planning Department) In addition to the functions of the notification plan creation unit 37 in Embodiment 2, the notification plan creation unit 39 further has the function of modifying the notification plan based on the progress of the waterworks construction work.

[0149] The notification plan creation unit 39 modifies the notification plan D15 based on the progress information D71 output by the third computing terminal 70.

[0150] Figure 9 shows an example of modifying the notification plan D15 based on progress information D71.

[0151] Referring to Figures 7 and 8, as well as Figure 9, the server device 10 updates the construction schedule in the work plan information D21 based on the progress information D71. Because the construction is behind schedule, the construction schedule is extended until 12:00 on XX / XX / 20XX. Store B opens at 11:00. Therefore, due to the change in the construction schedule in the work plan information D21, the new construction schedule D271 overlaps not only with the business hours of store A but also with the business hours of store B.

[0152] Therefore, the notification planning unit 39 decides to notify the manager of building BLD1 or store A that the construction schedule has been postponed. The notification planning unit 39 also decides to notify the manager of building BLD2 or store B that, due to the postponement of the construction schedule, store B is now included in the scope of the new construction schedule D271.

[0153] Furthermore, the notification plan creation unit 39 may also revise the notification plan D15 if the construction is progressing ahead of schedule. For example, if the construction schedule is updated at 6:00 on XX / XX / 20XX based on progress information D71 because the construction is ahead of schedule, the notification plan creation unit 39 may, in the new construction schedule, notify the manager of building BLD1 or store A that the construction will be completed ahead of schedule before the construction is completed.

[0154] With the above configuration, the notification plan D15 can be modified according to the progress of the waterworks construction. According to the above configuration, even if an unexpected situation occurs at the construction site, the notification plan D15 can be modified according to the situation.

[0155] [Other embodiments] Although embodiments of the present invention have been described above, the embodiments described above are merely examples for carrying out the present invention. Therefore, the invention is not limited to the embodiments described above, and it is possible to carry out the invention by appropriately modifying the embodiments described above without departing from the spirit of the invention.

[0156] Although not specifically described in the above embodiments, the functions of each component of the water management information processing device and the water management information processing system may be implemented by software or by hardware. The functions of each component of the water management information processing device and the water management information processing system may also be implemented using a trained model obtained by machine learning. Although not specifically described in embodiments 2 and 3, the programs executed to implement the functions of each component of the water management information processing system are also within the scope of the present invention.

[0157] Although not specifically described in Embodiment 2 above, the first and second computing terminals may be the same terminal. Furthermore, the water management information processing system does not need to have a second computing terminal.

[0158] In embodiments 2 and 3 described above, the field survey information output unit 61 of the second computing terminal 60 outputs the field survey information D61 to the server device 10. However, a headquarters staff member who receives the field survey results in writing may input the field survey information D61 to the server device 10 using the first computing terminal. The water management information processing system does not necessarily have a second computing terminal.

[0159] Although not specifically described in Embodiment 3 above, the third computing terminal may be the same terminal as at least one of the first computing terminal or the second computing terminal.

[0160] In embodiments 2 and 3 described above, the notification planning units 37 and 39 plan to notify the store if the construction schedule overlaps with the store's business hours. However, the notification planning units may also plan to notify the store if the construction schedule does not overlap with the store's business hours. For example, if a predetermined delay in the construction schedule would cause it to overlap with the store's business hours, the notification planning units may plan to notify the store that the delay in construction will have an impact.

[0161] In embodiments 2 and 3 described above, the server device 10 has a hydraulic analysis execution unit 31. However, the server device does not have to have a hydraulic analysis execution unit. The hydraulic analysis result-related information acquisition unit of the server device may acquire hydraulic analysis information from another server device.

[0162] In the above embodiment 3, the notification plan creation unit 39 modifies the notification plan based on the progress information D71. However, the impact area estimation unit may re-estimate the impact area based on the progress information.

[0163] In embodiments 2 and 3 described above, the water supply management information processing systems SYS2 and SYS3 are computer network systems including a server device 10. However, each function of the water supply management information processing system may be implemented by a water supply management information processing device.

[0164] For example, in a water supply management information processing device, the influence range estimation unit may estimate the influence range for each type of hydraulic change.

[0165] Furthermore, for example, the water supply management information processing device may further include: a hydraulic analysis execution unit that creates at least one candidate valve operation pattern for a valve to be operated based on the work plan for the water supply construction and performs hydraulic analysis based on the created candidate valve operation pattern; a first pattern determination unit that determines a first pattern of a valve to be operated from the candidate valve operation pattern based on the results of the hydraulic analysis; a field survey information acquisition unit that acquires field survey information that investigates items related to the water supply construction in the construction area that is the target of the water supply construction in which the valve is operated with the first pattern; and a second pattern creation unit that creates a second pattern in which at least some of the valves included in the first pattern are changed based on the field survey information. The hydraulic analysis result related information acquisition unit may acquire hydraulic analysis result related information when the valve is operated with the second pattern.

[0166] As described above, the server device and the water management information processing device create patterns for operating valves in two stages: the determination of the first pattern in the first pattern determination unit and the creation of the second pattern in the second pattern creation unit. However, the server device and the water management information processing device may create patterns in three or more stages. That is, the server device and the water management information processing device may have a first-stage pattern creation unit, a second-stage pattern creation unit, ... and an nth-stage pattern creation unit. Each stage's pattern creation unit may create one pattern or multiple patterns. Furthermore, the final nth-stage pattern creation unit may create one pattern or multiple patterns. Moreover, in the case of two stages, the final second-stage pattern creation unit may create multiple patterns.

[0167] Furthermore, for example, in a water supply management information processing device, the field survey information acquisition unit may acquire the field survey information, which includes information regarding the use of roads or facilities located in the construction area. The water supply management information processing device may also further include a notification plan creation unit that creates a notification plan, which is a notification plan for the construction area, based on the field survey information and the scope of impact.

[0168] Furthermore, for example, the water supply management information processing device may further include a notification unit that notifies the persons to be notified in the construction area in accordance with the notification plan.

[0169] Furthermore, for example, the water supply management information processing device may further include a work progress information acquisition unit that acquires progress information regarding the progress of the water supply construction work. The notification plan creation unit may modify the notification plan based on the progress information. [Industrial applicability]
