Description

[Technical field]

[0001] An embodiment of the present invention relates to a water leakage accident response system, a water leakage accident response method, and a program. [Background technology]

[0002] In recent years, the number of local government employees involved in waterworks has been declining due to organizational downsizing and the retirement of the baby boomer generation, and the number of experienced and skilled workers is also decreasing. While human resources are decreasing, water pipes are aging and water leakage accidents are on the rise. Under these circumstances, water leakage accidents occur suddenly regardless of whether it is at night or on a holiday, so it is necessary to respond more quickly and appropriately and efficiently.

[0008] Hereinafter, an embodiment will be described with reference to the drawings.

[0009] <System configuration overview> FIG. 1 shows an example of the functional configuration of a water leakage accident response system according to an embodiment and an information terminal that can access the system.

[0010] The water leakage accident response system 1 shown in Fig. 1 corresponds to one or more servers (computers) used by a local government in the water supply business to respond to a water leakage accident. The server may be located in a designated government building of the local government, or may be located in a location other than the government building, for example, anywhere on the Internet (cloud). The various functions provided in the water leakage accident response system 1 are configured as a program or database to be realized by one or more servers (computers). Below, the water leakage accident response system 1 may be abbreviated to system 1.

[0011] 1 is an information terminal (e.g., a personal computer, a tablet terminal, or a smartphone) used by a local government employee of the waterworks, and terminal T' is an information terminal (e.g., a personal computer, a tablet terminal, or a smartphone) used by an ordinary resident. Each of terminals T and T' is used as a client terminal that can access the server of system 1.

[0012] Here, before describing in detail each function provided in the water leakage accident response system 1 and each function provided in each terminal T, the data input and output in the water leakage accident response system 1 will be described.

[0013] <Various types of data> FIG. 2 shows examples of various types of data that are input and output in the water leakage accident response system shown in FIG.

[0014] The types of data input to the system 1 include data input on the day, data input in advance, and accident processing data. The types of data output from the system 1 include output data. Each type of data will be explained in turn below.

[0015] (1) Data entered on the day The data entered on that day is data that local government staff enters and registers from terminal T to system 1 during the period from the occurrence of an accident to the completion of accident response. The data entered on that day includes staff data and accident situation data.

[0016] (1.1) Personnel Data The employee data includes data on attendance status. The data on attendance status indicates the number and names of employees who are at work for each team (water supply team, facilities team, pipeline team, and general affairs team). Each team inputs this information from their terminal T. Employee data may also be collected automatically using location information (GPS) or the ON / OFF status of employee computers.

[0017] The water supply team is responsible for providing emergency water supply to areas where water has been cut off due to a leak (for example, distributing water to residents using water trucks, etc.). The facilities team is responsible for operating and managing the water purification facilities or water distribution facilities that supply water to the pipelines in the water cut-off areas (for example, adjusting the increase or decrease in the amount of purified water at the water purification facility or the amount of water distributed at the distribution facility). The pipeline team is responsible for emergency restoration of pipelines where water has leaked (for example, pipe repair work). The general affairs team is responsible for supporting the activities of the water supply team, facilities team, and pipeline team, coordinating these teams, and publicizing the team to the outside world. Depending on the size of the local government, one employee may be in charge of multiple teams, or the role of the general affairs team may be handled by one person rather than a team, but this is not a problem.

[0018] (1.2) Accident situation data The accident status data indicates the status of a water leakage accident, and includes accident-related data and progress status data.

[0019] The accident-related data indicates the estimated leak location, the estimated leak amount, the date and time of the accident, etc. This information is obtained by the pipeline team by checking the accident situation on-site, and is entered by the pipeline team from terminal T.

[0020] The progress status data includes information showing the progress of the accident response by the water supply team, facility team, and pipeline team (progress of emergency water supply, progress of operation and management of facilities that purify or distribute water, progress of emergency restoration of pipelines where water leakage occurred), as well as information disseminated by the general affairs team as public relations on the progress status of each team. This information is sequentially input by the water supply team, facility team, pipeline team, and general affairs team from terminal T.

[0021] (2) Pre-fill data Pre-entered data is data that is registered in System 1 before an accident occurs, and is basically entered and registered in System 1 by local government employees from Terminal T, but System 1 may automatically receive and store data from other systems through data communications with those systems. Pre-entered data includes facility data other than waterworks data, owned equipment and materials data, contact data, and waterworks facility data.

[0022] (2.1) Data on facilities other than water supply The data on facilities other than waterworks is input by the pipeline team from terminal T and includes information on facilities other than waterworks, such as buried pipes for communication cables, and information on nearby construction work.

[0023] (2.2) Equipment and materials data The equipment data includes information on emergency water supply equipment and the number and type of water trucks, etc., as information input by the water supply team from terminal T. The equipment data also includes information on equipment such as pipelines and valves, as information input by the pipeline team from terminal T.

[0024] (2.3) Contact data The contact data is information entered by the pipeline team from terminal T, and includes information on related organizations such as the contact points of partner companies.

[0025] (2.4) Water facility data The water facility data includes information input by the water supply team from the terminal T, which includes information indicating water supply points (including information indicating the priority order of each water supply point) and information indicating the amount of stored water.

[0026] The waterworks facility data includes information input by the facilities team from terminal T indicating the capacity of each water purification and distribution facility, as well as information indicating associated equipment such as installed pipelines and valves.

[0027] The water facility data, which is input by the pipeline team from terminal T, includes information on installed pipelines, valves, and other ancillary facilities, as well as priority route data that indicates the priority of routes. The priority route data gives higher priority to routes that have pipelines that lead to important facilities.

[0028] (3) Accident handling data The accident processing data is data that local government staff inputs and registers from terminal T to system 1 when a water leakage accident response is completed in order to record the entire accident response.

[0029] Specifically, the accident processing data that the water supply team inputs from terminal T when the accident response is completed includes information indicating the details of the emergency water supply process (water supply location / work time / amount of water supplied / water supply location / number of times water was supplied, etc.).

[0030] In addition, the accident processing data that the facility team inputs from terminal T when the accident response is completed includes information indicating the processing details of the facility operation management (such as the water distribution adjustment status of each facility).

[0031] In addition, the accident processing data that the pipeline team inputs from terminal T when they have finished responding to an accident includes information indicating the details of emergency restoration processing (location, damage situation (leakage amount, leak location, etc.), response time, equipment used, etc.).

[0032] In addition, the information entered by the general affairs team from terminal T when the accident response is completed includes information indicating the contents of the public relations information sent out (contact with residents and the media, contact and request status with external organizations, etc.).

[0033] (4) Output data The output data includes planning data, public relations data, and accident record data.

[0034] (4.1) Planning Data The plan data is data indicating the formulated emergency water supply plan, facility operation management plan, and emergency restoration plan. The water supply team, facility team, and pipeline team each carry out emergency water supply, operation management, and emergency restoration based on the plan data corresponding to their team.

[0035] (4.2) Public relations data The public relations data is data showing the schedule for emergency water supply or the expected restoration of water supply as public relations material. The General Affairs Team disseminates the public relations data to the outside world using the local government's website, email distribution, and other means.

[0036] (4.3) Accident record data Accident record data is information in a specified format that shows the circumstances of the accident and a record of all the countermeasures taken, and is created based on information entered and registered by the water supply team, facilities team, pipeline team, and general affairs team.

[0037] <Functions of Water Leakage Accident Response System 1 and Terminal T> As described above, the water leakage accident response system 1 and each terminal T shown in Fig. 1 have various functions. Hereinafter, the various functions will be described one by one.

[0038] Functions related to processing data entered on the day (staff data, accident status data) As functions related to processing of the data input on that day (staff data, accident situation data), terminal T has a staff data input unit 11 and an accident situation data input unit 21, and system 1 has a staff data acquisition unit 12, a staff data storage unit 13, an accident situation data acquisition unit 22, and an accident situation data storage unit 23. Note that staff data input unit 11 and accident situation data input unit 21 may be realized as separate terminals (PC, smartphone, tablet, etc.).

[0039] The staff data input unit 11 inputs staff data in response to input operations on the terminal T. When the staff data is input, the system 1 causes the terminal T to display a screen that guides the user in inputting the staff data. The input staff data is sent to the system 1. The staff data acquisition unit 12 acquires the staff data input by the staff data input unit 11.

[0040] The staff data storage unit 13 stores the staff data acquired by the staff data acquisition unit 12. The staff data can be viewed from any terminal T. The staff data is also used by the formulation unit 50, which will be described later, for the formulation of an emergency water supply plan, an operation management plan, and an emergency restoration plan.

[0041] The accident situation data input unit 21 inputs accident situation data (accident-related data, progress status data) in response to an input operation of the terminal T. When inputting the accident situation data, the system 1 causes the terminal T to display a screen that guides the input of the accident situation data. The input accident situation data is sent to the system 1. The accident situation data acquisition unit 22 acquires the accident situation data input by the accident situation data input unit 21.

[0042] The accident status data storage unit 23 stores the accident status data (accident-related data, progress status data) acquired by the accident status data acquisition unit 22. The accident status data can be viewed from any terminal T as information that can be shared by the personnel in charge of each plan. The accident status data is also used by the formulation unit 50, which will be described later, for the formulation of an emergency water supply plan, an operation management plan, an emergency restoration plan, and public relations materials.

[0043] Functions related to the processing of pre-filled data As a function related to the processing of pre-input data, the system 1 has a pre-input data storage unit 31 that stores pre-input data. As described above, the pre-input data includes facility data other than water supply, owned equipment and materials data, contact information data, and water supply facility data. The pre-input data may be acquired by input from the terminal T as described above, but may also be acquired from another system through data communication with the other system. The pre-input data is used in the formulation unit 50, which will be described later, for the respective processes of formulation of an emergency water supply plan, formulation of an operation management plan, and formulation of an emergency restoration plan.

[0045] The accident processing data input unit 41 inputs accident processing data in response to input operations on the terminal T. When inputting the accident processing data, the system 1 causes the terminal T to display a screen that guides the user in inputting the accident processing data. The input accident processing data is sent to the system 1. The accident processing data acquisition unit 42 acquires the accident processing data input by the accident processing data input unit 41, and extracts from the acquired accident processing data data that can be used as reference material for formulating future plans (past response data).

[0046] The accident processing data storage unit 43 stores the accident processing data acquired by the accident processing data acquisition unit 42. The accident processing data can be viewed using any terminal T. The accident processing data is also used in the process of formulating an accident record in the formulation unit 50, which will be described later. The past response data storage unit 44 stores the past response data extracted by the accident processing data acquisition unit 42. The past response data can be viewed using any terminal T. The past response data is also used in the process of formulating an emergency water supply plan, an operation management plan, and an emergency restoration plan in the formulation unit 50, which will be described later.

[0047] Functions related to formulation processing As functions related to the planning process, the water leakage accident response system 1 has a planning unit 50 and a planning data storage unit 60. The water leakage accident response system 1 also has a GIS (Geographic Information System) data storage unit 61 that can be used by the planning unit 50 and a display control unit 72 (described later). The GIS data storage unit 61 stores map information obtained from the GIS.

[0048] The map information may include information indicating the locations of hospitals, parks, etc. that may serve as water supply points (points where water is distributed to residents) in the event of a water leak accident, information indicating the locations of water purification plants that may serve as supply points (points where water is refilled for water trucks), water distribution reservoirs and disaster storage tanks located at various locations, information indicating water distribution bases or water purification bases (the locations of water distribution facilities or water purification facilities that adjust the amount of water distributed or purified), and information indicating the locations of individual pipelines and valves.

[0049] The planning unit 50 uses accident status data (accident-related data, progress status data) indicating the accident status of the water leakage accident, pre-input data input in advance, map information, etc., to determine the water-cut area, etc. according to a specified algorithm or calculation formula, and formulates an emergency water supply plan for the water-cut area, an operation and management plan for facilities that supply water to the pipelines in the water-cut area, and an emergency restoration plan for the pipeline where the leak occurred.

[0050] The formulation unit 50 further has various functions as described below.

[0051] For example, the formulation unit 50 has a function of creating information in which priorities are assigned to a plurality of water-supply points in formulating an emergency water-supply plan.

[0052] Furthermore, the plan formulation unit 50 has a function of creating information showing water supply points on a map together with the location of water leakage when formulating an emergency water supply plan.

[0053] Furthermore, the plan formulation unit 50 has a function of creating information showing on a map a plurality of water supply points, to which priority has been assigned, together with the location of the water leak, in the formulation of an emergency water supply plan.

[0054] Furthermore, the planning unit 50 has a function of creating information showing the location of water leakage as well as water distribution bases or water purification bases on a map when formulating an operation and management plan.

[0055] In addition, when formulating an operation and management plan, the formulation unit 50 has a function of creating information showing water distribution bases or water purification bases on a map along with the location of water leaks, and a graph showing changes over time in the water distribution volume at the water distribution base or the water purification volume at the water purification base.

[0056] In addition, when formulating an operation and management plan, the formulation unit 50 has a function of creating information showing water distribution bases or water purification bases on a map along with the location of water leaks, a graph showing changes over time in the water distribution volume of the water distribution base or the water purification volume of the water purification base, and information showing the recommended water distribution volume of the water distribution base or the recommended water purification volume of the water purification base.

[0057] Furthermore, the formulation unit 50 has a function of creating information showing on a map the location of the water leak as well as the pipelines and valves requiring operation that are to be subjected to emergency restoration when formulating an emergency restoration plan.

[0058] The formulation unit 50 also has a function of formulating an accident record showing a record of responses to water leakage accidents, and storing the formulated accident record as data that can be used for subsequent formulations.

[0059] The formulation unit 50 also has a function of formulating public relations materials indicating a schedule for emergency water supply or an expected restoration date for water supply, using the accident status data.

[0060] The formulation unit 50 also has a function of determining the allocation of personnel in charge of each plan based on data indicating the attendance status of employees.

[0061] The planning unit 50 also has a function of creating data showing the progress of accident response as information that can be shared by personnel in charge of each plan.

[0062] More specifically, the planning department 50 has an emergency water supply plan planning department 51, an operation and management plan planning department 52, an emergency restoration plan planning department 53, a public relations material planning department 54, and an accident record planning department 55.

[0063] The emergency water supply plan formulation unit 51 formulates an emergency water supply plan (emergency water supply plan) for which the water supply team is responsible, using staff data in the staff data storage unit 13, accident situation data in the accident situation data storage unit 23, pre-input data in the pre-input data storage unit 31, and past response data in the past response data storage unit 44.

[0064] The operation management plan formulation unit 52 uses the staff data in the staff data storage unit 13, the accident situation data in the accident situation data storage unit 23, the pre-input data in the pre-input data storage unit 31, and the past response data in the past response data storage unit 44 to formulate an operation management plan (operation management plan) for the facilities under the responsibility of the facilities team.

[0065] The emergency restoration plan formulation unit 53 uses the staff data in the staff data storage unit 13, the accident situation data in the accident situation data storage unit 23, the pre-input data in the pre-input data storage unit 31, and the past response data in the past response data storage unit 44 to formulate an emergency restoration plan (emergency restoration plan) for which the pipeline team is responsible.

[0066] The accident record creation unit 55 uses the accident processing data in the accident processing data storage unit 43 to create accident records for each of the water supply team, facility team, pipeline team, and general affairs team.

[0067] The formulation data memory unit 60 stores data (plan data) on emergency water supply plans, operation management plans, and emergency recovery plans formulated by the emergency water supply plan formulation unit 51, the operation management plan formulation unit 52, and the emergency recovery plan formulation unit 53, respectively, data on public relations materials (public relations data) formulated by the public relations material formulation unit 54, and data on accident records (accident record data) formulated by the accident record formulation unit 55.

[0068] If there is a plan that has been edited and approved by the approval and editing unit 76 described later, the data of that plan will be reflected in the corresponding plan data in the formulated data storage unit 60 via the approval and edited data acquisition unit 77.

[0069] Functions related to processing planning data As functions related to the plan data, the system 1 has a provided data creation unit 71, a display control unit 72, an email sending unit 74, and an approval / editing data acquisition unit 77, and the terminal T has a display unit 73, an email receiving unit 75, and an approval / editing unit 76. Note that the display unit 73, the email receiving unit 75, and the approval / editing unit 76 may be realized by separate terminals.

[0070] The provided data creation unit 71 creates data in a format suitable for providing to the water supply team, the facilities team, and the pipeline team based on the plan data for the emergency water supply plan, the operation management plan, and the emergency restoration plan in the formulated data storage unit 60. The data created includes data in a format suitable for screen display on the terminal T, as well as email data for sending email notifications.

[0071] The display control unit 72 causes the display unit 73 to display the data created by the provided data creation unit 71. At that time, the display control unit 72 uses map information stored in the GIS data storage unit 61 as necessary, and controls so that information indicating the emergency water supply plan, operation management plan, or emergency restoration plan is displayed together with a map including the location of the water leakage accident. In addition, at the time of display, it is possible to distinguish whether the plan displayed is one approved by the team leader or a plan (draft) before approval. The specific content displayed differs depending on the emergency water supply plan, operation management plan, or emergency restoration plan. Specific examples of display will be described later.

[0072] The mail sending unit 74 sends the mail data created by the provided data creating unit 71 to the terminal T. The mail data may be, for example, a notification that the formulation of the plan has been completed or a request for approval of the plan (draft). The mail receiving unit 75 receives the mail data sent from the mail sending unit 74 and displays it on the display unit 73 or the like.

[0073] The approval / editing unit 76 edits and approves the plan (draft) displayed on the display unit 73 in response to input operations on the terminal T. When editing or approving the plan (draft), the system 1 causes the terminal T to display a screen that guides the user in editing or approving the plan (draft). The approval / editing data acquisition unit 77 acquires the data of the plan edited and approved by the approval / editing unit 76, and reflects it in the corresponding plan data in the formulation data storage unit 60.

[0074] Functions related to the processing of public relations data As functions relating to the processing of public relations data, the system 1 has a provision data creation unit 81 and a display control unit 82, and the terminal T' has a display unit 83.

[0076] The display control unit 82 causes the display unit 83 to display the data created by the provided data creation unit 81 .

[0077] -Functions related to processing accident record data As functions related to the processing of the accident record data, the system 1 has a provided data creation unit 91 and a display control unit 92, and the terminal T has a display unit 93.

[0078] The provided data creation unit 91 creates data in a format suitable for providing for confirmation of the accident record based on the accident record data in the formulation data storage unit 60. The created data is data in a format suitable for display on the screen of the terminal T.

[0079] The display control unit 92 causes the display unit 93 to display the data created by the provided data creation unit 91 .

[0080] <Basic work procedure> Here, an example of a basic work procedure when a water leakage accident occurs will be shown. However, the example of the work procedure shown here is only an example and is not limited to this. The work procedure may be changed as appropriate.

[0081] Step 1 When a local government that manages a water supply business receives a report of a water leakage accident, an accident response headquarters is set up and an initial response system is established, while a pipeline team goes to the site and confirms the accident situation. At this time, a local government employee inputs and registers staff data indicating the staff member who will be handling the water leakage accident, and accident situation data indicating the accident situation (i.e., the data entered on that day) from terminal T to system 1.

[0082] Step 2 At the accident response headquarters, the general affairs team, water supply team, facilities team, and pipeline team all work in parallel to respond to the water leak accident.

[0083] The general affairs team is responsible for public relations, the water supply team is responsible for emergency water supply, the facilities team is responsible for operation management, and the pipeline team is responsible for emergency restoration. The progress of the accident response is shared with each team on an ongoing basis, primarily by the general affairs team. Staff members of the general affairs team, water supply team, facilities team, and pipeline team can use their own terminals T to input information into the water leakage accident response system 1 and view information output by the water leakage accident response system 1 on a screen. The progress of the accident response for each team is input into the water leakage accident response system 1 as progress data and stored in the accident status data storage unit 23.

[0084] Step 3 The pipeline team goes to the site, investigates the accident situation, and inputs and registers the results of the investigation as accident situation data from terminal T into system 1. In the formulation section 50 in system 1, an emergency restoration plan is formulated based on the accident situation data, etc., and an emergency water supply plan, an operation management plan, and public relations materials are also formulated. Furthermore, the pipeline team uses terminal T to obtain the emergency restoration plan formulated by the water leakage accident response system 1.

[0085] In addition, in formulating the emergency recovery plan, past response data extracted from past accident processing data is used as reference material. For example, from among multiple past response data, past response data that shows a situation that is closest to the situation of the current accident (for example, past response data with the same estimated population, area, and estimated amount of leakage) may be used.

[0086] Step 4 Next, the pipeline team will carry out emergency restoration work in accordance with the acquired emergency restoration plan.

[0087] Step 5 In addition, the water supply team, the facilities team, and the general affairs team also use terminals T to obtain the emergency water supply plan, the operation management plan, and the public relations materials formulated by the water leakage accident response system 1.

[0088] Step 6 Next, the water supply team, facilities team, and general affairs team will carry out emergency water supply, operation management, and public relations activities in accordance with the emergency water supply plan, operation management plan, and public relations materials that they have acquired, respectively.

[0089] Step 7 Once the accident response is complete, the pipeline team, water supply team, facilities team, and general affairs team each input and register the accident processing data showing the results of emergency restoration work, emergency water supply, operation management, and public relations activities into System 1 from Terminal T.

[0090] In the formulation unit 50 in the system 1, the accident record formulation unit 55 formulates an accident record indicated in the accident processing data, and stores the accident record in the accident record data formulation data storage unit 60 as accident record data.

[0091] The accident record data stored in the formulation data memory unit 60 can be viewed from any terminal T, and can also be used for maintenance plans for repaired pipelines, basic information for renewal plans, and updating information on drawings and ledgers.

[0092] <Workflow for each team responding to an accident> Each staff member of the accident response headquarters can share information using their own terminal T, communicate information with each other, hold meetings, and access System 1. For example, the progress and results of work in each team, and reports of problems and delays can be shared between the teams through System 1. Additionally, information within each team can be shared between team leaders and team members.

[0093] FIG. 3 shows an example of the workflow of accident response by the general affairs team, pipeline team, facility team, and water supply team. However, the example shown in FIG. 3 is just one example and is not limited to this. The workflow (such as the order of each step) shown in FIG. 3 may be changed as appropriate. In the following, the head of the accident response headquarters will be referred to as the "head of headquarters."

[0094] When a water leakage accident occurs, an accident response headquarters is set up and an initial response system is established (step S11).

[0095] When establishing an initial response system, all staff members are assigned to each department. The status of staff assignment for each team is entered and registered in System 1 as staff data from Terminal T, and is communicated to the Chief of Headquarters via the General Affairs Team from the Pipeline Team, Facility Team, and Water Supply Team. At that time, the information may be sent by email to Terminal T owned by each team or the Chief of Headquarters.

[0096] The pipeline team goes to the site, investigates the damage to the water facility and the water outage, and takes emergency measures (step S12). The results of the investigation and the details of the emergency measures are input and registered in the system 1 from terminal T as accident status data, and are communicated to the general affairs team. At that time, the general affairs team may be notified by email to terminal T owned by the general affairs team.

[0097] The facilities team checks the formulation of the operation management plan by the system 1 and gets approval for it from the team leader. Furthermore, the facilities team performs operation management of the facility (adjusting the increase / decrease of the purified water volume at the water purification facility, etc.) in accordance with the operation management plan (step S13). The operation management of the facility continues until the implementation of the operation management plan is completed, and the contents are continuously communicated to the general affairs team.

[0098] The general affairs team confirms the damage situation based on the reports from the pipeline team and the facilities team, and starts accepting calls for lifelines, etc. (Step S14). The contents are conveyed to the headquarters chief.

[0099] Next, the chief and each team decide on the system required for emergency water supply and emergency restoration through a meeting or the like based on the contents of the reports from each team (step S15).

[0100] The pipeline team confirms the formulation of the emergency restoration plan by the system 1 and obtains approval for it from the team leader (step S16). The contents of the emergency restoration plan are communicated to the general affairs team. Furthermore, the pipeline team makes a deployment request to the pipeline restoration contractor in accordance with the emergency restoration plan (step S17). The contents of the deployment request are communicated to the general affairs team.

[0101] The pipeline team also secures emergency restoration materials and equipment in accordance with the emergency restoration plan (step S18). The details of the emergency restoration materials and equipment to be secured are communicated to the general affairs team. Furthermore, the pipeline team implements emergency restoration work in accordance with the operation management plan and investigates water quality (step S19).

[0102] The water supply team checks the formulation of the emergency water supply plan by the system 1 and gets approval for it from the team leader (step S20). The contents of the emergency water supply plan are communicated to the general affairs team. Furthermore, the water supply team implements emergency water supply in accordance with the emergency water supply plan (step S21).

[0103] Based on the report of the emergency water supply plan from the water supply team, the general affairs team requests other water suppliers to provide water supply support and deploys them as necessary (step S22). The details are then conveyed to the head of the headquarters.

[0104] The General Affairs Team also secures necessary supplies based on the emergency restoration plan report and deployment request from the pipeline team. Furthermore, based on the individual reports from the pipeline team, facility team, and water supply team, the General Affairs Team notifies citizens and contacts relevant agencies such as the national government, police, and fire department (step S23). The details are conveyed to the headquarters chief.

[0105] When the implementation of each plan is completed, the general affairs team, pipeline team, facilities team, and water supply team each create a corresponding accident record (step S24).

[0106] Specifically, the general affairs team, pipeline team, facilities team, and water supply team each input and register the corresponding accident processing data from terminal T to system 1. Within system 1, the accident processing data is compiled and stored as an accident record. The contents of the accident record are communicated to the headquarters chief.

[0107] This completes each team's accident response work.

[0108] <Example of emergency water supply plan display> Next, a display example of an emergency water supply plan will be described.

[0109] The emergency water supply plan formulated by the formulation unit 50 in the system 1 is displayed on the display unit 73 of the terminal T via the formulation data storage unit 60, the provided data creation unit 71, and the display control unit 72.

[0110] Fig. 4 shows an example of displaying a part of an emergency water supply plan as mapping information on a map. Also, Fig. 5 shows an example of displaying a part of an emergency water supply plan as table information. The mapping information in Fig. 4 and the table information in Fig. 5 are displayed simultaneously on one screen.

[0111] As shown in FIG. 4, the display unit 73 of the terminal T displays a frame on a map indicating the assumed water outage area where a water outage is assumed to occur, as well as marks (circle, cross, square (black)) indicating the recommended water supply point, the location of the leak, and the resupply point, each with a priority order (number). In addition, assumed water outage area information (information including the assumed population, area, assumed amount of leak, and total required daily supply) is displayed as numerical information of the assumed water outage area. Note that, although FIG. 4 shows an example in which the assumed water outage area is surrounded by a straight frame, the method of expressing the assumed water outage area is not limited to this example. For example, the boundary line of the assumed water outage area may be expressed by polygon information (a collection of multiple polygons) for each district. In that case, it is not limited to straight lines and may also include curves.

[0112] The recommended water supply points indicate points (such as hospitals and parks) that distribute water to residents and that are recommended by the system 1. For example, among the water supply points that exist in various locations, only those within the estimated water outage area are displayed. The leak location indicates the location where the leak is occurring. The supply points indicate points where water is supplied to water trucks (such as water purification plants, water distribution reservoirs, and disaster storage tanks located in various locations). Only supply points that are within the estimated water outage area or within a certain distance from the estimated water outage area are displayed.

[0113] The priority order of the recommended water supply points is determined by the formulating unit 50 using a predetermined algorithm or calculation formula based on the accident situation data and the pre-input data. For example, the priority order may be determined according to the priority order registered in advance in the system 1, or based on the priority route data. In addition, the priority order may be set so that the closer the water supply point is to the water leak position, the higher the priority order, or the higher the water supply capacity (water supply amount) of the water supply point is.

[0114] In addition, as shown in Figure 5, the display unit 73 of terminal T displays table information including detailed information for each recommended water supply point with a priority order (number), namely, the specific location of the water supply point (A Hospital, B Park, ...), water supply method (water truck, tank supply, ...), required equipment (○○○, △△△, ...), water supply personnel / vehicles (○ people / ○ units, △ people, ...), etc.

[0115] In addition to detailed information for each recommended water supply point, table information may be displayed that includes detailed information on the location of the leak (the specific address (or name) of the leak location, and a photo (image) of the leak location if the pipeline team has registered a photo of the leak location in system 1), as well as detailed information for each resupply point (the specific address (or name) of the resupply point, the amount of water stored, the water supply method, etc.).

[0116] The total daily supply required, water supply method, necessary equipment, water supply personnel and vehicles, etc. mentioned above are determined according to a prescribed algorithm or formula based on the population affected by the water outage at the water supply point, the specifications of the water tank (whether or not it has an outlet, etc.), etc.

[0117] In the mapping information of FIG. 4, related information may be displayed in a pop-up by clicking on any mark (circle, cross, black square).

[0118] For example, when the "circle" mark is clicked on, detailed information about the recommended water supply point (such as the specific location of the water supply point, the water supply method, etc.), i.e., information similar to the table information in Figure 5, may be displayed in a pop-up that is easy to visually confirm.

[0119] In addition, by clicking on the "X" mark, a pop-up may be displayed with detailed information about the location of the leak (the specific address (or name) of the leak location, and if the pipeline team has registered a photo of the leak location in System 1, a photo (image) of the photo).

[0120] In addition, when the black square mark is clicked on, detailed information about the supply point (such as the specific address (or name) of the supply point, the amount of water stored, the water supply method, etc.) may be displayed in a pop-up.

[0121] <Example of operation management plan> Next, a display example of the operation management plan will be described.

[0122] The operation management plan formulated by the formulation unit 50 in the system 1 is displayed on the display unit 73 of the terminal T via the formulation data storage unit 60, the provided data creation unit 71, and the display control unit 72.

[0123] Fig. 6 shows an example of displaying a part of an operation management plan as mapping information on a map. Also, Fig. 7 shows an example of displaying a part of an operation management plan as graph information. The mapping information in Fig. 6 and the graph information in Fig. 7 are displayed simultaneously on one screen.

[0124] As shown in Figure 6, the display unit 73 of terminal T displays a frame on a map indicating the estimated water outage area where a water outage is assumed to have occurred, along with marks (x, square (black)) indicating the location of the water leak and the water distribution center (facility), and further displays estimated water outage area information (information including estimated population, area, estimated leakage amount, and total daily required supply) as numerical information about the estimated water outage area.

[0125] A water distribution base indicates a facility that performs operation management such as adjusting the increase and decrease of the amount of water distributed, and may overlap with the above-mentioned resupply points. Note that, as an example here, a case is given in which a water distribution base (such as a water distribution reservoir) that can adjust the amount of water distributed is present on the map, but there may also be a water purification base (such as a water purification plant) that can adjust the amount of purified water. Only water distribution bases and water purification bases within the expected water outage area or within a certain distance from the expected water outage area are displayed.

[0126] In addition, as shown in FIG. 7, the display unit 73 of the terminal T displays graph information showing the change over time in the water distribution amount for each water distribution base station, and information showing the recommended water distribution amount for each water distribution base station.

[0127] If there are water purification sites, graph information showing the change over time in the amount of purified water at each water purification site and information showing the recommended amount of purified water at each water purification site are displayed.

[0128] In the example of FIG. 7, a graph showing the change over time in the water distribution amount of each of a plurality of water reservoirs A and B, and information on the recommended water distribution amount are displayed.

[0129] The recommended water distribution volume and recommended water purification volume are determined according to a predetermined algorithm or formula based on the population affected by the expected water outage in the area, the specifications of the distribution reservoir and water purification plant, etc.

[0130] However, the recommended water distribution amount (or recommended water purification amount) is not necessarily a fixed value, and may be a variable value. For example, the normal water storage amount of a water distribution reservoir (or water purification plant) may be recorded every few months, and the average value multiplied by a certain percentage (e.g., 30%) may be used as a threshold value. If the actual water storage amount exceeds the threshold value, it may be recommended to increase the water distribution amount (or water purification amount) by the difference from the threshold value.

[0131] The operation management plan is implemented according to the recommendations as described above. If an abnormality occurs in the amount of water distributed (or the amount of water purified), the abnormality may be detected by the system 1 and the abnormality may be notified to staff by displaying or sending an e-mail to the staff's terminal T. For example, the occurrence of an abnormality may be detected when the amount of water distributed (or the amount of water purified) deviates from a certain threshold range or when the rate of change of the amount of water distributed (or the amount of water purified) exceeds a certain level.

[0132] In the mapping information of FIG. 6, related information may be displayed in a pop-up by clicking on any mark (x, black square).

[0133] For example, when the "X" mark is clicked on, a pop-up may be displayed with detailed information about the location of the leak (the specific address (or name) of the leak location, and if the pipeline team has registered a photo of the leak location in System 1, a photo (image) of the photo).

[0134] In addition, by clicking on the black square mark, detailed information about the water distribution base (such as the specific address (or name) of the water distribution base, the amount of water stored, the water supply method, etc.) may be displayed in a pop-up.

[0135] <Example of emergency recovery plan display> Next, a display example of the emergency restoration plan will be described.

[0136] The emergency restoration plan formulated by the formulation unit 50 in the system 1 is displayed on the display unit 73 of the terminal T via the formulation data storage unit 60, the provided data 71, and the display control unit 72.

[0137] FIG. 8 shows an example of displaying part of an emergency restoration plan as mapping information on a map.

[0138] As shown in FIG. 8, the display unit 73 of terminal T displays a mark (X) indicating the location of the leak on a map, as well as marks (□ (black)) indicating pipelines that are the subject of emergency restoration and valves that require operation. In addition to this, table information may be displayed that includes detailed information on the location of the leak, such as the amount of leak and the state of damage, and, if the pipeline team has registered a photo of the location of the leak in system 1, a photo (image) of that photo. This information is determined based on information registered in system 1, such as the damage and buried state of the pipeline.

[0139] In addition, although not shown in FIG. 8, the display unit 73 of the terminal T displays information indicating the steps of the emergency restoration plan.

[0140] An example of the steps in an emergency recovery plan is shown below. The numbers in parentheses indicate the order of the steps.

[0141] (1) Closing valves in affected sections, (2) Pipe restoration work, (3) Filling the pipes with water, (4) Checking water pressure, (5) Investigating leaks, (6) Repairing leaking areas, (7) Cleaning the pipes, (8) Water quality testing, (9) Turning water on.

[0142] In particular, for processes such as (1), (3), and (7) (processes requiring valve operation), it is desirable to display the operating valve in the mapping display described above, and for process (2), it is desirable to display the restoration method including the damage status and information on buried pipes / nearby construction. In addition, it is desirable to display information such as the organization of restoration work teams and the necessary emergency restoration equipment and materials. These are determined from the attendance status data and the damaged / buried status of the pipeline.

[0143] <Example of emergency water supply plan creation> 9 shows an example of the operation of formulating an emergency water-supply plan by the formulating unit 50. The formulation of an emergency water-supply plan is performed by an emergency water-supply plan formulating unit 51.

[0144] First, the formulation unit 50 judges whether or not accident status data (particularly accident-related data) has been input and registered in the system by the pipeline team (step S51). If input and registration have not been performed, the process returns to step S51, and if input and registration have been performed, the process proceeds to step S52.

[0145] Next, the formulating unit 50 checks the accident situation data (step S52), and identifies the expected water outage area from the accident situation data and map information obtained from the GIS (step S53). The formulating unit 50 calculates the water outage population from the water outage area (step S54).

[0146] Next, the formulation unit 50 creates an emergency water supply plan (draft) based on the accident situation data, the calculated water outage area / water outage population, the data input on the day, the data input in advance, and the past response data (step S55), and displays the created emergency water supply plan (draft) on the screen of the terminal T (step S56). The emergency water supply plan (draft) is confirmed by the plan formulation staff, and once approval is obtained from the team leader, it is completed as an official emergency water supply plan.

[0147] Next, the formulation unit 50 judges whether the emergency water supply plan (draft) has been approved by the team leader (step S57). If not approved (rejected), the formulation unit 50 confirms that the plan has been edited by the plan formulation staff (step S58) and returns to step S57. If approved, the process proceeds to step S59.

[0148] Finally, the formulation unit 50 notifies the terminals T of the respective persons in charge of the emergency water supply team and the related persons that the emergency water supply plan has been completed (step S59).

[0149] <Example of operation management plan creation> 10 shows an example of the operation of formulating an operation management plan by the formulating unit 50. The formulating of an operation management plan is performed by the operation management plan formulating unit 52.

[0150] First, the formulation unit 50 judges whether or not accident status data (particularly accident-related data) has been input and registered in the system by the pipeline team (step S61). If input and registration have not been performed, the process returns to step S61, and if input and registration have been performed, the process proceeds to step S62.

[0151] Next, the planning unit 50 checks the accident situation data (step S62), creates an operation management plan (draft) for each facility based on the accident situation data, the data input on the day, the data input in advance, and the past response data (step S63), and displays the created operation management plan (draft) on the screen of the terminal T (step S64). The operation management plan (draft) is checked by the person in charge of planning, and once approval is obtained from the team leader, it is completed as an official operation management plan.

[0152] Next, the planning unit 50 judges whether the operation management plan (draft) has been approved by the team leader (step S65). If it has not been approved (if it has been rejected), the planning unit 50 confirms that the plan has been edited by the person in charge of planning (step S66) and returns to step S57. If it has been approved, the process proceeds to step S59.

[0153] Finally, the formulation unit 50 notifies the terminals T of the facility team members in charge of facility operation management and the related parties that the operation management plan has been completed (step S67).

[0154] <Example of emergency recovery plan creation> 11 shows an example of the operation of formulating an emergency restoration plan by the formulating unit 50. The formulation of an emergency restoration plan is performed by the emergency restoration plan formulating unit 52.

[0155] First, the formulation unit 50 judges whether or not accident status data (particularly accident-related data) has been input and registered in the system by the pipeline team (step S71). If input and registration have not been performed, the process returns to step S71, and if input and registration have been performed, the process proceeds to step S72.

[0156] Next, the formulation unit 50 checks the accident situation data (step S72), creates an emergency recovery plan (draft) for each facility based on the accident situation data, the data input on the day, the data input in advance, and the past response data (step S73), and displays the created emergency recovery plan (draft) on the screen of the terminal T (step S74). The emergency recovery plan (draft) is checked by the plan formulation staff, and once approval is obtained from the team leader, it is completed as an official emergency recovery plan.

[0157] Next, the formulation unit 50 judges whether the emergency recovery plan (draft) has been approved by the team leader (step S75). If not approved (rejected), the formulation unit 50 confirms that the plan has been edited by the plan formulation staff (step S76) and returns to step S57. If approved, the formulation unit 50 proceeds to step S59.

[0158] Finally, the formulation unit 50 notifies the terminals T of the respective members of the facility team in charge of emergency restoration of the facility and the related persons that the emergency restoration plan has been completed (step S77).

[0159] <Summary> As mentioned above, System 1 automatically creates plans for not only emergency restoration but also emergency water supply and facility management, and also creates public relations materials and accident records, so that the general affairs team, water supply team, facility team, and pipeline team can easily obtain corresponding plans without much effort or time, even if they have few experienced staff, and can quickly and appropriately respond to water leakage accidents according to those plans, achieving early restoration of normal water supply. In addition, public relations activities to inform residents and the media of accident occurrences and water outages can also be easily carried out.

[0160] As described above in detail, according to the embodiment, when a water leakage accident occurs, it is possible to take prompt and appropriate accident response. [Explanation of symbols]
