Description

[Technical Field]

[0001] The present invention relates to a power outage area display system, a power outage area display method, and a display screen that can provide power outage information indicating whether or not there is a power outage at road facilities not only to consumers but also to third parties when a widespread power outage is implemented due to the occurrence of a large-scale disaster or for other reasons. [Background technology]

[0002] When a power plant stops operating due to a large-scale disaster, etc., the demand for electricity may exceed the supply capacity of the power generation facilities. When such a power shortage occurs, in order to adjust the load, so-called planned power outages may be implemented, in which the transmission and distribution system from the power company's substation to the customer's home (demand home) is cut off on a system-by-system basis, thereby halting the transmission and distribution of electricity. In addition to the planned power outages mentioned above, transmission and distribution of electricity from a specific distribution system to customer homes (demand homes) may be suspended if transmission equipment breaks down due to a disaster or other reason, or if large-scale maintenance is performed on transmission equipment.

[0003] Furthermore, when rolling blackouts are implemented, the power supply area is generally divided into several groups, and each group is assigned a time period during which the blackouts are turned off in turn. These groups are divided into groups based on the system units that make up the power distribution system, and in many cases do not correspond to the administrative divisions of municipalities. This makes it difficult to inform customers of the blackouts by administrative division, and even customers in the same administrative division may find themselves in a situation where their home is experiencing a power outage while their neighbors are not. More specifically, after the Great East Japan Earthquake, similar situations occurred when rolling blackouts were implemented due to a power supply shortage, and it was reported that confusion among neighbors was not uncommon. Furthermore, when power transmission equipment breaks down due to a disaster or when large-scale maintenance is performed on power transmission equipment, power outages also occur on a system-by-system basis that make up the power distribution system, and similar issues arise.

[0004] In both cases, electric power companies were inundated with inquiries about the affected areas from customers and third parties visiting the affected areas, which created the further problem of making it difficult to communicate accurate and timely information about the affected areas to customers and others. As a prior application for addressing the above-mentioned problems, for example, Patent Document 1 shown below, filed by the same applicant as the present invention, is known.

[0005] Patent Document 1, titled "Power System Management System and Power System Management Method," discloses an invention relating to a system and method for informing consumers of a widespread power outage when a large-scale disaster occurs. The power system management system disclosed in Patent Document 1, using the reference numerals shown in FIG. 5 in the document, acquires a group ID of a power outage (S501). Next, based on power outage information 15D, it identifies a system number 15D2 from the acquired group ID 15D1 (S502), and performs steps S503 to S506 for each system number. Then, based on system information 15A, it identifies a bank pole number 15A2 from the identified system number 15A1 (S503), and performs steps S504 to S506 for each bank pole number. Next, based on equipment information 15B, it identifies a service pole number 15B1 from the identified bank pole number 15B2 (S504), and performs steps S505 to S506 for each service pole number. Then, based on the customer information 15C, the customer ID 15C1 is identified from the identified service pole number 15C2 (S505), and the icon of the customer home of each customer ID on the map information 15E is colored in a color that indicates the group of power outages at that customer home (S506). According to the invention disclosed in Patent Document 1 as described above, it is possible to quickly inform consumers of information regarding planned power outages and power outages.

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-58091 Summary of the Invention [Problem to be solved by the invention]

[0007] When taking into consideration the invention disclosed in Patent Document 1, it is not possible to determine whether road facilities such as traffic lights and electronic signboards installed at the boundaries of areas affected by power outages will be affected by the power outage. In this case, a problem arose in that third parties other than consumers who were visiting areas where planned power outages were taking place or areas where power outages had occurred due to a large-scale disaster, etc., from outside for travel or to provide support, etc., were unable to accurately assess the traffic conditions in those areas. In this case, there was a concern that when third parties other than consumers visit areas affected by a power outage from outside to provide support, particularly in the event of a disaster, problems may arise, such as being unable to reach their destination smoothly, which could delay the start of support.

[0008] The present invention has been made in response to such conventional circumstances, and its purpose is to provide a power outage area display system, a power outage area display method, and a display screen that can generate a power outage area map that can determine whether transportation equipment installed within a power outage area or on the border of a power outage area will be subject to a power outage. [Means for solving the problem]

[0009] The first invention for solving the above problem is a power outage area display system that identifies consumers and road facilities that receive power from a power distribution system and sets a power outage area on a map from these consumers and road facilities, and includes power distribution system map data that shows distribution system lines that indicate the layout of the power distribution system, utility poles that are installed in the power distribution system and are associated with the power distribution system, a system number that is a number unique to the power distribution system, and a utility pole number that is a number unique to the utility pole, and a service pole that is part of the utility pole and supplies power to a building of the consumer, and the building that is associated with the service pole. The system is characterized by comprising: a means for storing customer management map data and road facility management map data showing the road facilities that receive power from the distribution system and are associated with the distribution system; a means for identifying buildings and road facilities that will be subject to a power outage based on the distribution system map data, the customer management map data, the road facility management map data, and the acquired power outage system number; a means for setting a power outage area on a map so as to include the buildings and road facilities that will be subject to the power outage; and a means for outputting the power outage area to a public map on which road facility icons indicating the road facilities are displayed. In the first invention having the above configuration, the distribution system map data showing the distribution system lines indicating the layout of the distribution system, the utility poles installed in the distribution system and associated with the distribution system, the system number which is a number unique to the distribution system, and the utility pole number which is a number unique to the utility pole are used by electric power companies for management, maintenance, inspection, etc. of power transmission equipment. In addition, in the first invention, the customer management map data showing the service pole that is part of the utility pole and supplies power to the customer's building, and the building that is associated with this service pole, is used by the electric power company to manage customers under a contract in which the power usage fee is determined according to the amount of power used. Furthermore, in the first invention, the road facility management map data showing the road facilities that receive power from a power distribution system and are associated with the power distribution system is used by electric power companies to manage road facilities under contracts in which power usage fees are determined without measuring the amount of power used. In the first aspect of the present invention, the power outage system number is acquired to identify the power distribution system that is the target of the power outage. In addition, in the first invention, the buildings and road facilities that are subject to power outages are identified based on map data (= composite map) that is created by unifying the scales of the distribution system map data, customer management map data, and road facility management map data and combining (layer stacking) them, and the previously identified power outage system number. Furthermore, by setting a power outage area to include all buildings and road facilities that are subject to power outages and that are identified on the composite map, and outputting the set power outage area to a public map, electricity consumers and third parties can view the public map that displays this power outage area and determine whether the consumer's home (building) is subject to power outages and whether the road facilities displayed on the public map are subject to power outages.

[0010] A second invention is the above-mentioned first invention, characterized in that the road facilities include street lights. According to the second invention having the above configuration, by viewing a public map showing the power outage area, it is possible to determine whether the street lights (road facilities) shown on the public map will be subject to a power outage.

[0011] A third invention is the above-mentioned first or second invention, characterized in that the public map does not display power distribution system lines and utility poles. According to the third aspect of the invention having the above configuration, information relating to the distribution system and the layout of utility poles is not disclosed, which has the effect of preventing the information relating to the distribution system and the layout of utility poles from being misused.

[0012] A fourth invention is the first or second invention described above, characterized in that the power outage area and the time when the power outage will occur are displayed on the public map. According to the third aspect of the present invention having the above configuration, when a public map showing a power outage area is viewed, information regarding the timing of power outage implementation in that power outage area can also be obtained.

[0013] The fifth invention, a power outage area display method, is characterized in that the power outage area obtained by the power outage area display system of the first invention is displayed on a public map. The fifth invention having the above-mentioned configuration is a specification of the first invention as a method invention, and its action is the same as that of the first invention.

[0014] The display screen of the sixth invention is characterized in that the power outage area including the building icons and road facility icons indicating the customer buildings that are subject to the power outage is displayed on a map that does not display the power distribution system lines and utility poles installed in the power distribution system that show the layout of the power distribution system that supplies power to customers and road facilities, but displays road facility icons indicating the road facilities. The sixth invention having the above configuration specifies as an invention a display screen that displays a public map showing a power outage area generated according to the third invention. Therefore, the function of the sixth invention is the same as the function of the third invention. [Effects of the Invention]

[0015] According to the first or fifth invention as described above, by displaying icons indicating road facilities on the public map showing the power outage area, in addition to information on whether the customer's building will be affected by the power outage, information on whether the road facilities displayed on the public map will be affected by the power outage can also be provided. In this case, travel plans can be made and travel can be made taking into account the power outage status of road facilities installed within or on the borders of the power outage area. In other words, by viewing the public map that displays the power outage area generated by the first invention, if you obtain information that road equipment installed on a road you plan to travel will be subject to a power outage, you can take measures such as avoiding that road for safety reasons. Therefore, according to the first or fifth invention, it is possible to provide more useful information when people are active within a power outage area or on its borders. Furthermore, information on whether road facilities installed within or on the borders of a power outage area will be subject to a power outage is also useful to third parties other than consumers. Therefore, according to the first or fifth invention, it is possible to provide useful information to third parties other than consumers when they are active in the power outage area or its borders.

[0016] According to the second invention, it is also possible to provide the viewer with information as to whether or not the street lights displayed on the public map are subject to a power outage. In this case, when traveling at night within a power outage area or around its borders, more useful information can be provided for determining the safety of roads to be traveled. Therefore, according to the second invention, it is possible to further improve the convenience of the public map on which the power outage area is displayed.

[0017] According to the third or sixth invention, the risk of a malicious third party harming the power distribution system or utility poles can be reduced by not displaying the power distribution system or utility poles on the public map showing the power outage area, which means that terrorism against the power distribution system, which is a lifeline, can be prevented. Therefore, according to the third or sixth aspect of the present invention, it is possible to provide a public map that displays power outage areas, which is useful from the viewpoint of security.

[0018] According to the fourth invention, viewers can obtain information not only about the power outage area but also about the timing of the power outage, thereby providing more useful information when people are active within the power outage area or on its borders.

[0020] A power outage area display system, a power outage area display method, and a display screen according to an embodiment of the present invention will be described in detail with reference to FIGS.

[0021] [1;About the power outage area display system] First, an outline of a power outage area display system according to an embodiment of the present invention (hereinafter referred to as the present embodiment) will be described with reference to FIG. FIG. 1 is a system configuration diagram of a power outage area display system according to this embodiment. As shown in Figure 1, the power outage area display system 1 of this embodiment mainly comprises a CPU 3 which is a storage processing unit, a database 4 which stores various map data etc., and a server device 2 which has a communication unit 5 and an input / output unit 6, and is used to generate public map data 11' (see Figure 18 shown below) which displays the power outage area based on the various map data stored in the database 4. In addition, the public map data 11' (see Figure 18 shown later) displaying the power outage area generated by the power outage area display system 1 of this embodiment is made public via an information and communication network 110 such as the Internet, and can be viewed using user terminals 100a to 100c, such as computers or smartphones. 1, the user terminal 100a, such as a computer or smartphone, includes at least a CPU 101, which is a storage processing unit, a storage unit (memory) 102, a communication unit 103, and a monitor or display, which is an input / output unit 104. The same is true for the user terminals 100b, 100c, etc.

[0022] <1-1;About the database> The data structure of the database 4 of the power outage area display system 1 according to this embodiment and the data structure of each piece of data stored in this database 4 will be described with reference to FIGS. 2 to 11. FIG. FIG. 2 is a conceptual diagram showing the data structure of a database in the power outage area display system according to this embodiment. As shown in Figure 2, the database 4 stores power outage management data 7, distribution system map data 8, customer management map data 9, road facility management map data 10, public map data (without power outage area display) 11, and public map data (with power outage area display) 11'.

[0023] The power outage management data 7 stored in the database 4 is information relating to the system number to be powered off when a planned power outage or the like is carried out, the timing of the power outage, and the like, which will be explained later with reference to FIG. The power distribution system map data 8 is a map that is mainly used by electric power companies for the management, maintenance, inspection, etc. of power transmission facilities. The consumer management map data 9 is a map used by an electric power company to manage consumers (customers) under a contract in which the electricity usage fee is determined mainly according to the amount of electricity used. The road facility management map data 10 is a map used by electric power companies to manage road facilities under a contract in which the electricity usage fee is determined without measuring the amount of electricity used. In the electric power company, the distribution system map data 8, the customer management map data 9, and the road facility management map data 10 are managed and used by servers or computers in different departments. Therefore, when implementing the present invention, the latest distribution system map data 8, customer management map data 9, and road facility management map data 10 are obtained from the server device or computer of each department when necessary, and stored in the database 4 for use.

[0024] The public map data 11 stored in the database 4 is a map that is used as a base when the power outage area data 25 generated in accordance with the procedure described below is made public. The public map data 11' is a map generated by combining (layering) the power outage area data 25 with the public map data 11.

[0025] (About power outage management data) The power outage management data 7 is information about systems that are subject to power outage due to planned power outages or other reasons, and the timing of the power outages. Here, the power distribution system and planned power outages will be described with reference to Fig. 3. Fig. 3A is an image diagram of the power distribution system, and Fig. 3B is an image diagram showing power outage time periods assigned to each group of planned power outages. As shown in FIG. 3A, the power distribution system (e.g., systems L1 to L5) is a high-voltage power distribution line that branches off from a transformer 121 in a substation and extends to an area where customer homes (demanding customers) to which power should be supplied are located via circuit breakers (e.g., circuit breakers 122a to 122e). In addition, although not specifically shown in Figure 3A, bank poles are installed in each system (for example, systems L1 to L5), and service lines (low-voltage wiring) branch off from these bank poles, and power is supplied to each customer's home (demanding facility) through these service lines.

[0026] Furthermore, when a planned power outage is carried out, the planned power outages are grouped by system (for example, systems L1 to L5; feeder units) according to the amount of power demand at each customer's home (consumer), as shown in FIG. 3A, for example. More specifically, as shown in FIG. 3A, for example, system 1 (L1) belongs to group A, system 2 (L2) and system 3 (L3) belong to group B, and system 4 (L4) and system 5 (L5) belong to group C. Planned power outages may be carried out on a system basis (for example, systems L1 to L5) or on a bank basis (bank pole basis) as described above. When a planned power outage is implemented, the power outage time is varied for each group, for example, as shown in Figure 3B, with Group A experiencing a power outage from 9:00 to 12:00, Group B experiencing a power outage from 18:00 to 21:00, and Group C experiencing a power outage from 21:00 to 24:00.

[0027] In addition to planned power outages, power outages caused by natural disasters or the like also occur on a system-by-system or bank-by-bank basis. In this embodiment, the case where a power outage is performed on a system basis has been described as an example, but the case where a power outage is performed on a bank basis is also included in the technical scope of the present invention.

[0028] Therefore, the power outage management data 7 stored in the database 4 is a combination of the system number(s) of the system that will be affected by the power outage and the implementation time, particularly in the case of planned power outages, and is the system number(s) of the system that will be affected by the power outage in the case of a power outage caused by a natural disaster or the like. In addition, in the case of a power outage caused by the occurrence of a natural disaster or the like, and the period required for restoration is clear, the combination of the system number (singular or plural) of the system subject to the power outage and the implementation time becomes the power outage management data 7.

[0029] (About the power distribution system map data) The power distribution system map data and the power distribution system map will be described with reference to FIGS. FIG. 4 is a conceptual diagram showing the data structure of the distribution system map data, and FIG. 5 is an image of the distribution system map. The power distribution system map data 8 shown in Fig. 4 is expressed as a map in the power distribution system map 8 in Fig. 5. For this reason, the same symbols are used for corresponding components in Fig. 4 and Fig. 5. Furthermore, each piece of data constituting the power distribution system map data 8 includes its location information (GPS information, etc.).

[0030] As shown in Figures 4 and 5, the distribution system map data (distribution system map) 8 is mainly composed of road data (roads) 12, topography data (topography) 13 indicating, for example, mountains, rivers, coasts, etc., facility equipment data (facility equipment) 14 indicating, for example, facilities and equipment such as public facilities, hospitals, shrines and temples, building data (buildings) 15 indicating the buildings of each customer, distribution system line data (distribution system lines) 16 indicating the layout of the distribution system, system number data (system number) 17 indicating the unique number of each system (for example, notation such as "L1", "L2" in Figure 5), utility pole data (utility poles) 18 installed in each distribution system and associated with the above-mentioned wiring system, and utility pole number data (utility pole number) 19 which is a number unique to each utility pole 18 (for example, notation such as "XXXX" in Figure 5). Although not particularly shown, the power distribution system map data (power distribution system map) 8 may further include data on place names (such as prefecture names, city / town / village names) and addresses. By using the distribution system map 8 shown in Fig. 5, it is possible to grasp the layout of each distribution system on the map (distribution system lines 16), their system numbers 17, and even the layout of each utility pole 18 belonging to each system and their utility pole numbers 19. Such a distribution system map 8 is used by electric power companies for the management, maintenance, and inspection of distribution systems.

[0031] (About customer management map data) The customer management map data and the customer management map will be described with reference to FIGS. 6 and 7. FIG. FIG. 6 is a conceptual diagram showing the data structure of the customer management map data, and FIG. 7 is an image diagram of the customer management map. The consumer management map 9 in Figure 7 is a map representation of the consumer management map data 9 shown in Figure 6. For this reason, the same symbols are used for corresponding components in Figures 6 and 7. Furthermore, each piece of data that makes up the consumer management map data 9 includes its location information (GPS information, etc.).

[0032] As shown in Figures 6 and 7, the customer management map data (customer management map) 9 is mainly composed of road data (roads) 12, topography data (topography) 13 indicating, for example, mountains, rivers, coasts, etc., facility equipment data (facility equipment) 14 indicating, for example, facilities and equipment such as public facilities, hospitals, shrines and temples, building data (buildings) 15 indicating the buildings of each customer, and house name data 20 indicating the unique names of each building 15 (for example, the notation "SSSS" in Figure 7). In addition, in the consumer management map data (consumer management map) 9, each building data (building) 15 is associated with service pole data (service pole) 18a that directly supplies power. More specifically, in the customer management map 9, each building 15 is associated with the utility pole 18a that directly supplies power to it by connecting them with a straight line, but the method of associating them is not limited to that shown in Figure 9. More specifically, the buildings 15 may be associated with each other by, for example, writing on each building 15 the utility pole number 19 of the utility pole 18a that supplies power to each building 15 . Alternatively, each building 15 may be associated with the utility pole number 19 of the service pole 18a that supplies power to the building 15 in the consumer management map data 9 that is not displayed on the consumer management map 9 (see FIG. 7). It should be noted that a part of the utility pole data (utility pole) 18 is used as a lead-in utility pole 18a.

[0033] Although not particularly shown, the customer management map data (customer management map) 9 may further include data relating to place names (such as prefecture names, city / town / village names) and addresses. By using the customer management map 9 shown in Figure 7, the location of the customer's building 15 on the map, its name 20, and the location and pole number 19 of the service pole (utility pole) 18 that directly supplies power to the building 15 can be easily grasped. Such a consumer management map 9 is used by the electric power company to manage the amount of power used by each consumer and to provide various services.

[0034] (About road facility management map data) The road facility management map data and the road facility management map will be described with reference to FIGS. FIG. 8 is a conceptual diagram showing the data structure of road facility management map data, and FIG. 9 is an image diagram of the road facility management map. The road facility management map data 10 shown in Figure 8 is expressed as a map in the form of the road facility management map 10 in Figure 9. For this reason, the same symbols are used for corresponding components in Figures 8 and 9. Furthermore, each piece of data that makes up the road facility management map data 10 includes its location information (GPS information, etc.).

[0035] As shown in Figures 8 and 9, road facility management map data (road facility management map) 10 is mainly composed of road data (roads) 12, terrain data (terrain) 13 indicating, for example, mountains, rivers, coasts, etc., facility equipment data (facility equipment) 14 indicating, for example, facility equipment such as public facilities, hospitals, shrines, temples, etc., building data (buildings) 15 indicating the buildings of each customer, utility pole data (utility poles) 18 and utility pole number data (utility pole numbers) 19 which are numbers unique to each utility pole 18, traffic light data (traffic lights) 21 and traffic light number data (traffic light numbers) 22 which are numbers unique to each traffic light 21 (for example, the notation "UUU" in Figure 9), and street light data (street lights) 23 and street light number data (street light numbers) 24 which are numbers unique to each street light 23 (for example, the notation "TTT" in Figure 9). Although not specifically shown, the traffic lights 21 and street lights 23 are associated with a power distribution system that supplies power to them.

[0036] Although not particularly shown, the road facility management map data (road facility management map) 10 may further include data relating to place names (prefecture names, city, town, village names, etc.) and addresses. By using the road facility management map 10 shown in FIG. 9, the position of the traffic light 21 and the traffic light number 22, and the position of the street light 23 and the street light number 24 on the map can be easily grasped. Such a road facility management map 10 is used by an electric power company to manage, maintain, and inspect power supply facilities for traffic lights 21 and street lights 23. In this embodiment, the concept of the traffic light data (signal) 21 includes an electronic bulletin board that notifies road information and congestion information.

[0037] (Regarding public map data) The public map data and the public map (without display of power outage areas) will be described with reference to FIGS. 10 and 11. FIG. FIG. 10 is a conceptual diagram showing the data structure of public map data, and FIG. 11 is an image of the public map (without display of blackout areas). The public map in Figure 11 (without showing power outage areas) is a map representation of the public map data 11 shown in Figure 10. For this reason, the same reference numerals are used for corresponding components in Figures 10 and 11. Furthermore, each piece of data that makes up the public map data 11 includes its location information (GPS information, etc.).

[0038] The public map data (public map) 11 is a map used as a base when power outage area data (power outage area) 25, which is generated in the procedure described later, is made publicly available. In this embodiment, an example is given in which power outage area data 25 is made public using public map data 11 prepared separately from the power distribution system map data 8, customer management map data 9, and road facility management map data 10, but power outage area data 25 may also be made public using a map that displays only the desired data in the composite map 26 shown below (see Figure 13 below). In this case, the public map data 11 is the composite map 26 (see FIG. 13) shown later on, on which the desired data is displayed.

[0039] More specifically, as shown in Figures 10 and 11, the public map data (public map) 11 is mainly composed of road data (roads) 12, topography data (topography) 13 indicating, for example, mountains, rivers, coasts, etc., facility equipment data (facility equipment) 14 indicating, for example, facilities and equipment such as public facilities, hospitals, shrines and temples, building data (buildings) 15 indicating the buildings of each customer, traffic light data (traffic lights) 21, and street light data (street lights) 23. Although not shown, the public map data (public map) 11 may further include data on place names (such as prefecture names, city / town / village names) and addresses.

[0040] The power outage area data (power outage area) 25 shown in the dashed frame in the public map data 11 shown in Figure 10 is data generated using the distribution system map data 8, consumer management map data 9, and road facility management map data 10 stored in the database 4, according to a procedure described later, and is data that is added (synthesized) when the public map data 11 is made public. It is also desirable to use the latest public map data 11 available.

[0041] <1-2: Procedure for generating power outage area data> A procedure for generating the power outage area data 25 using each piece of data stored in the database 4 of the power outage area display system 1 according to this embodiment will be described with reference to FIGS. Fig. 12 is a flowchart showing the procedure for generating power outage area data, and Figs. 13 to 18 are conceptual diagrams of the output obtained at each step. Moreover, each process (step) shown in FIG. 12 is executed by the server device 2 in the power outage area display system 1 according to this embodiment.

[0042] Step S01 when generating the power outage area data 25 is a process of identifying the system number (power outage system number) that is the target of the power outage from the power outage management data 7 stored in the database 4. In this embodiment, for convenience, the system 1 (L1) in the distribution system line data 16 shown in FIG. 5 and the like is assumed to be the target of the power outage.

[0043] Step S02 is a process of combining the latest power distribution system map data 8, customer management map data 9, and road facility management map data 10 obtained from each department within the electric power company and stored in the database 4, that is, stacking layers with the scale of each map unified, to obtain a composite map 26. An image of the composite map 26 obtained in step S02 is shown in Figure 13.

[0044] Step S03 is a process of identifying the buildings 15 that will be subject to the power outage, as well as the road facilities such as traffic lights 21 (including electronic bulletin boards) and street lights 23, based on the power outage system number identified in the previous step S01 and the composite map 26 obtained in the previous step S02. More specifically, in this step S03, all buildings 15 located at the terminals of system 1 (L1), which is the distribution system line data 16, in the composite map 26 shown in Figure 13, as well as all road equipment, which are traffic lights 21 (including electronic signboards) and street lights 23, also located at the terminals of system 1 (L1), are identified as targets for power outage. To make the processing in step S03 easier to understand, Figure 14 is an image diagram in which the buildings 15 (icons) identified as targets for power outages, as well as traffic lights 21 (icons; including electronic bulletin boards) and street lights 23 (icons) in the composite map 26 shown in Figure 13 above, are marked with identifying stars.

[0045] Step S04 is a process of identifying a power outage area based on the layout of the buildings 15 extracted (identified) in the previous step S03, as well as traffic lights 21 (including electronic bulletin boards), street lights 23, and the like. More specifically, step S04 is a process of extracting a power outage area 27 (the hatched area in Figure 15), which is a surface, by connecting adjacent buildings 15, traffic lights 21 (including electronic billboards), and street lights 23 that are subject to the power outage on the composite map 26, as well as utility poles 18 located on system 1 (L1) that are subject to the power outage as necessary, with lines, as shown in Figure 15, for example.

[0046] Step S05 is a process of extracting the contour line 27a of the blackout area 27 extracted (specified) in the previous step S04. 16 is an image diagram in which the outline 27a of the blackout area 27 (hatched portion) shown in FIG. 15 is emphasized by using a thick line.

[0047] Step S06 is a step of correcting the contour line 27a of the blackout area 27 extracted (specified) in the previous step S05 (optional). In the power outage area 27 (hatched area; see Figures 15 and 16) extracted (identified) in the previous step S05, the entire building 15 (icon representing it) that will be affected by the power outage, the traffic lights 21 (including electronic signboards), and the street lights 23 (icons representing them) are not included within the power outage area 27, especially at its boundaries. Therefore, if the outline 27a of the power outage area 27 shown in Figure 16 above is made public as the boundary position of the power outage area 27, and if a consumer or a third party views a map displaying this power outage area 27 using a user terminal 100a to 100c (see Figure 1), it may not be clear whether the building 15 or road equipment (traffic lights 21 and street lights 23) being checked is included in the power outage area 27. To avoid such a situation, in this embodiment, the contour line 27a of the blackout area 27 shown in FIG. 16 may be corrected as necessary.

[0048] More specifically, in step S06, when the power outage area 27 is synthesized (layer stacked) onto the previous public map data 11 to generate the public map data (public map) 11 for viewing, the contour line 27a may be corrected so that all of the building 15 icons affected by the power outage and the road facility icons (traffic light 21 icons and street light 23 icons) displayed in the public map data (public map) 11 for viewing are included within the power outage area. More specifically, as shown in Figure 17, for example, the contour line 27a may be extended as far as desired outside the power outage area 27 to generate a corrected contour line 27b (see the thick dashed line in Figure 17) in which all of the building 15 icons affected by the power outage and the road facility icons (traffic light 21 icons and street light 23 icons) are included within the power outage area.

[0049] Furthermore, if the corrected contour line 27b is not straight but has, for example, a sawtooth (jagged) shape, in order to make the corrected contour line 27b easier to see, the contour line may be corrected to a straight line that minimizes the unevenness that makes up the contour, or the corrected contour line 27b may be generated using a line parallel to the latitude or longitude line, or both of the above corrections may be performed simultaneously (see the thick dashed line in Figure 17). The area surrounded by the corrected contour line 27b generated in step S06 is the power outage area data (power outage area) 25. If step S06 is not performed, the area surrounded by the contour line 27a obtained in the previous step S05 becomes the power outage area data (power outage area) 25.

[0050] Step S07 is a process of synthesizing (layer stacking) the corrected contour line 27b (power outage area data 25) obtained in the previous step S06 with the previous public map 11 (see FIG. 11) at the same scale. FIG. 18 is an image of a public map 11' for viewing obtained by combining the corrected contour lines 27b (power outage area data 25) with the public map 11 (see FIG. 11). Furthermore, the public map 11' for viewing shown in FIG. 18 is a display screen displayed on the input / output unit 104 of the user terminals 100a to 100c, for example, a monitor or display.

[0051] Furthermore, the above-described steps S01 to S07 correspond to the respective processing steps of a power outage area display method 28 when the power outage area display system 1 according to this embodiment is considered as a method invention.

[0052] [2; Effects of the present invention] According to the power outage area display system 1 or power outage area display method 28 of this embodiment, a power outage area 25 is synthesized (layer stacked) onto a public map 11 on which road facility icons indicating road facilities such as traffic lights 21 and street lights 23 are displayed to generate a public map 11' (see Figure 18), thereby providing information on whether or not a building 15 (icon) displayed in the public map 11' will be subject to a power outage, as well as information on whether or not the road facilities displayed in the public map 11' will be subject to a power outage. Furthermore, such information can be easily viewed by consumers or other third parties using user terminals 100a to 100c, etc. In this case, there is no need to contact an operator of the power company to confirm the power outage area, which saves both the consumer or other third party and the power company time when obtaining or providing power outage information.

[0053] In this case, activities can be carried out while taking into consideration the power outage situation of road facilities (such as traffic lights 21 and street lights 23) installed within the power outage area 25 or on its borders. In other words, if you view the public map 11' as shown in Figure 18 above and find information that, for example, road facilities on the road you are about to travel will be subject to a power outage, you can take measures such as avoiding that road for safety reasons. Therefore, the power outage area display system 1 or the power outage area display method 28 according to this embodiment can provide more useful information when people are active within the power outage area 25 or on its boundary.

[0054] Furthermore, the public map 11' as shown in FIG. 18 above is useful information not only for customers who live or do business in the power outage area 25, but also for third parties other than the customers. In other words, if the power outage in the power outage area 25 is caused by a natural disaster or the like, the public map 11' as shown in Figure 18 above will be useful information for people (= third parties) who visit the area to provide support or other activities.

[0055] [3; Regarding detailed configurations and variations of the present invention] (Regarding the public map showing the power outage area) The public map 11' shown in FIG. 18 may be configured such that the distribution system lines 16 and utility pole data 18 are not displayed. If the public map 11' shown in FIG. 18 displays the power distribution lines 16 and utility poles 18 (for example, icons), there is an increased risk that the information will be misused and that damage will be inflicted on the power distribution system or utility poles. On the other hand, if the distribution system lines 16 and utility poles 18 (for example, icons) are not displayed on the public map 11' shown in FIG. 18, the above-mentioned risks can be reduced. In other words, it will be possible to prevent terrorism against the power distribution system, which is a lifeline.

[0056] (Regarding the timing of power outages in blackout areas) The public map 11' shown in FIG. 18 may also display the power outage area 25 (corrected contour line 27b) along with the power outage implementation time (for example, the power outage implementation date, power outage time period, etc.). In addition, information regarding the timing of power outages may be stored in the database 4 as power outage management data 7, and may be configured to be obtainable together with the power outage system number when step S01 in the flowchart shown in Figure 12 (power outage area display method 28) is executed. In this case, more useful information can be provided for people to carry out activities within the power outage area 25 or on its borders.

[0057] (About the display screen) In the power outage area display system 1 of this embodiment, the display screen displayed on the monitor or display, which is the input / output unit 104 of the user terminals 100a to 100c, may be configured so that the power distribution system lines (e.g., power distribution system line 16) indicating the power distribution system supplying power to consumers and road equipment and the utility poles (e.g., utility pole 18) installed on this power distribution system are not displayed, and road equipment icons indicating road equipment (icons indicating traffic lights 21 and icons indicating street lights 23) are displayed on the public map 11, and the power outage area 25 including an icon indicating a building 15 indicating a consumer building that is subject to the power outage and an icon indicating road equipment (traffic lights 21 and street lights 23) is displayed. In this case too, the power distribution system lines 16 and utility poles 18 (for example, icons) are not displayed on the display screen, so the risk of the information being misused and causing harm to the power distribution system or utility poles can be reduced. In other words, it will be possible to prevent terrorism against the power distribution system, which is a lifeline.

[0058] (About the components common to each map layer) If some or all of the sources of the distribution system map data (distribution system map) 8, consumer management map data (consumer management map) 9, and road facility management map data (road facility management map) 10 stored in the database 4 are different, utility pole data (utility pole) 18 and utility pole number data (utility pole number) 19 may be provided as data common to all of the distribution system map data (distribution system map) 8, consumer management map data (consumer management map) 9, and road facility management map data (road facility management map) 10. In this case, even if some or all of the providers of the distribution system map data (distribution system map) 8, customer management map data (customer management map) 9, and road facility management map data (road facility management map) 10 are different, step S02 (layer stacking) in the procedure for generating power outage area data 25 (power outage area display method 28) shown in Figure 12 above can be executed without any problems using utility pole data (utility pole) 18 and utility pole number data (utility pole number) 19 as keys.

[0059] [4;Other] In the power outage area display system 1 according to the present embodiment, the case where the server device 2 is used has been described as an example, but instead of the server device 2, a computer having a CPU (storage processing unit) may be used.

[0060] In this embodiment, the maps used to generate the public map data (public map) 11' are described using examples in which buildings 15, utility poles 18, traffic lights 21, and streetlights 23 are represented using icons that allow the object to be predicted from their shape, but it is not necessary to represent them using such icons, and pre-set symbols or the like may be used instead.

[0061] In addition, when buildings 15 are displayed as icons in the public map data (public map) 11', their planar shape and orientation (arrangement), and more preferably the planar size of the buildings 15, may be made to correspond to the planar shape of existing buildings 15. In this case, even if the name of the house is not displayed together with the icon representing the building 15 in the public map data (public map) 11', the owner or resident of the building 15 can easily determine whether the icon represents the building 15 that they own or live in by combining the icon representing the building 15 with the layout and topographical information of the surrounding roads, as well as optionally added place name information and address information. In this case, it is possible to determine whether the building 15 that one owns or resides in is included in the building that will be subject to power outage. Furthermore, in this case, when the public map data (public map) 11' is made public, personal information (such as the family name) relating to the building 15 can be hidden, making it possible to provide public map data (public map) 11' that is more useful from a security standpoint. [Industrial Applicability]

[0062] As described above, the present invention is a power outage area display system, a power outage area display method, and a display screen that can provide power outage information indicating whether or not there is a power outage at road equipment not only to consumers but also to third parties, and can be used in technical fields related to power transmission businesses.
