[0003] [Patent Document 1] JP 2020-114153 A Summary of the Invention [Problem to be solved by the invention]

[0004] Some buildings are equipped with a system that can supply power to the building from an external power source such as a battery-equipped vehicle during a power outage when commercial power supply is stopped. In such buildings, the electrical equipment in the building can be used continuously even during a power outage. However, since it is not possible to identify buildings in the area that require power supply, there is room for improvement in supplying power to buildings that require power quickly during a power outage.

[0005] In consideration of the above, an object of the present invention is to provide a display control device, a display control method, and a program that can quickly supply power to a building that requires power during a power outage. [Means for solving the problem]

[0006] The display control device of the first embodiment has a building information acquisition unit that acquires identification numbers and information regarding power supply from an external power source from each of a plurality of buildings within a section, a position identification unit that identifies a position on map data corresponding to each identification number acquired by the building information acquisition unit, and a display control unit that adds information regarding power supply from the external power source to the position on the map data identified by the position identification unit and displays it on a display device.

[0007] In the display control device according to the first aspect, the building information acquisition unit acquires identification numbers and information related to power supply from an external power source from each of a plurality of buildings in the section. The position identification unit identifies a position on the map data corresponding to each of the identification numbers acquired by the building information acquisition unit. The display control unit then adds information related to power supply from the external power source to the position on the map data identified by the position identification unit and displays the information on the display device. This allows residents to grasp information related to power supply from an external power source for each of the buildings in the section simply by looking at the display device. Note that the "information related to power supply from an external power source" is not limited to information on whether or not power is being supplied from an external power source, but is a concept that broadly includes the remaining amount of stored power in the external power source, etc.

[0008] In the display control device of the second aspect, in the first aspect, the building information acquisition unit acquires information as to whether or not power is being supplied from the external power source, and the display control unit displays on map data buildings that are being powered from the external power source by the building information acquisition unit and buildings that are not being powered from the external power source, distinguishing between the buildings.

[0009] In the display control device according to the second aspect, residents can know which buildings are not receiving power from an external power source simply by looking at the display device. This allows electric vehicles and hybrid vehicles to be directed to the buildings not receiving power as soon as possible.

[0010] A display control device according to a third aspect is the second aspect, in which the display control unit changes the display mode on map data for a building receiving power from the external power source in accordance with the amount of stored power in the external power source.

[0011] In the display control device according to the third aspect, the display mode on the map data changes according to the amount of stored power in the external power source, so that buildings with low stored power can be identified at a glance on the display device.

[0012] In a display control device of a fourth aspect, in the third aspect, the external power source is a vehicle equipped with a storage battery, and the display control unit changes the display mode on the map data depending on at least one of the amount of stored power and the remaining fuel of the storage battery in the vehicle.

[0013] In the display control device according to the fourth aspect, at least one of the amount of stored power and the remaining amount of fuel in the storage battery of the vehicle can be ascertained at a glance of the display device.

[0014] The display control device according to the fifth aspect is any one of the first to fourth aspects, and further includes a power supply request receiving unit that receives a power supply request from a user of a building, and when the power supply request receiving unit receives a power supply request, the display control unit displays a mark corresponding to the power supply request on map data for the building of the user who made the power supply request.

[0015] In the display control device according to the fifth aspect, a mark requesting power supply is displayed on the map data, so that the building requesting power supply can be ascertained at a glance of the display device.

[0016] A display control device according to a sixth aspect is any one of the first to fifth aspects, wherein the building information acquisition unit acquires the operation status of at least one of a power storage facility and a gas station within a section, and the display control unit displays the operation status acquired by the building information acquisition unit on map data.

[0017] In the display control device according to the sixth aspect, if the operation status of a power storage facility is displayed on the display device, residents can determine whether it is possible to charge a vehicle from the power storage facility. Also, if the operation status of a gas station is displayed on the display device, residents can determine whether it is possible to refuel a vehicle with gasoline.

[0018] A display control method according to a seventh aspect acquires identification numbers and information relating to power supply from an external power source from each of a plurality of buildings within a section, identifies a position on map data corresponding to each of the acquired identification numbers, and displays on a display device the information relating to power supply from the external power source at the identified position on the map data.

[0019] The program of the eighth aspect causes a computer to execute a process of acquiring identification numbers and information regarding power supply from an external power source from each of a plurality of buildings within a section, identifying a position on map data corresponding to each of the acquired identification numbers, and adding the information regarding power supply from the external power source to the identified position on the map data and displaying it on a display device. Effect of the Invention

[0020] As described above, according to the display control device, the display control method, and the program of the present invention, it is possible to quickly supply power to a building that requires power during a power outage. [Brief description of the drawings]

[0022] A display control device 10 according to an embodiment will be described with reference to the drawings. As shown in Fig. 1, the display control device 10 according to the embodiment is a device that displays information such as the power supply status of each dwelling unit (building) on ​​a mobile terminal 30 as a display device during a power outage, via an application running on the mobile terminal 30 carried by a resident in a specific block (area).

[0023] In the following description, as an example, each building in the section is provided with a device that can be powered from a vehicle as an external power source. Specifically, a cable attachment portion to which a cable for connecting to a vehicle is attached is provided on an outer wall of the building or around the building. The building and the vehicle can be electrically connected by attaching one end of the cable to the cable attachment portion and connecting the other end of the cable to the vehicle.

[0024] Furthermore, when a specific operation is performed while the building and the vehicle are electrically connected, power is supplied from a battery (storage battery) mounted on the vehicle to each electrical device in the building. Note that a V2H (Vehicle to Home) system, for example, is used to connect the building and the vehicle. The power supply is not limited to a method of supplying power by connecting a cable to the charging port of an electric vehicle or plug-in hybrid vehicle, but may be a method of supplying power by connecting a cable to a 100V accessory outlet mounted on a hybrid vehicle or the like.

[0025] (Hardware configuration of the display control device 10) The display control device 10 of this embodiment includes a CPU (Central Processing Unit: processor) 12, a ROM (Read Only Memory) 14, a RAM (Random Access Memory) 16, a storage 18, a communication interface 20, and an input / output interface 22. Each component is connected to each other via a bus 24 so as to be able to communicate with each other.

[0026] The CPU 12 is a central processing unit that executes various programs and controls each part. That is, the CPU 12 reads a program from the ROM 14 or the storage 18, and executes the program using the RAM 16 as a working area. The CPU 12 controls each of the above components and performs various arithmetic processing according to the program recorded in the ROM 14 or the storage 18.

[0027] The ROM 14 stores various programs and various data. The RAM 16 temporarily stores programs or data as a working area. The storage 18 is a non-temporary recording medium configured with an HDD (Hard Disk Drive) or an SSD (Solid State Drive) and stores various programs including an operating system and various data. In this embodiment, the ROM 14 or the storage 18 stores programs for executing various processes.

[0028] The communication interface 20 is an interface for the display control device 10 to communicate with external devices via the network N, and uses standards such as 5G, LTE, Wi-Fi (registered trademark), and Ethernet (registered trademark). In this embodiment, the communication interface 20 enables the display control device 10 to communicate with a mobile terminal 30 serving as a display device. The mobile terminal 30 is, for example, a smartphone carried by a user of the display control device 10, and data transmitted from the display control device 10 is displayed by starting a predetermined application from the mobile terminal 30.

[0029] The input / output interface (input / output I / F) 22 is an interface for connecting the display control device 10 to various input / output devices.

[0030] (Functional configuration of the display control device 10) The display control device 10 realizes various functions using the above hardware resources. The functional configuration realized by the display control device 10 will be described with reference to FIG.

[0031] 2, the display control device 10 includes, as functional components, a building information acquisition unit 32, a vehicle information acquisition unit 34, a position identification unit 36, a power supply request reception unit 38, and a display control unit 40. Each functional component is realized by the CPU 12 reading and executing a program stored in the ROM 14 or the storage 18.

[0032] The building information acquisition unit 32 acquires identification numbers from a plurality of buildings in a block. Specifically, an identification number is assigned to each building in a block, and the address (location information) of the building can be determined from this identification number. That is, each identification number and information on the building corresponding to the identification number are stored in a database, and the building information acquisition unit 32 acquires information on the building corresponding to each identification number by referring to the database.

[0033] Here, in this embodiment, as an example, information corresponding to the identification number is stored in the database, in addition to the address of the building, information on the mobile terminal 30 owned by the building user, and information on the vehicle owned by the building user.

[0034] Furthermore, the building information acquisition unit 32 acquires information regarding power supply from an external power source for each building in the section. In the present embodiment, as an example, the building information acquisition unit 32 acquires a signal from sensors provided in each building, and thereby acquires a signal indicating that power is being supplied from the vehicle to the building when power is being supplied from the vehicle to the building.

[0035] The vehicle information acquisition unit 34 acquires vehicle information registered in advance in a database. Specifically, the remaining amount of fuel according to the type of vehicle is acquired. For example, if the vehicle is an electric vehicle, the amount of stored power stored in the storage battery is acquired. Also, for example, if the vehicle is a hybrid vehicle, in addition to the amount of stored power stored in the storage battery, the remaining amount of liquid fuel such as gasoline is acquired. Furthermore, for example, if the vehicle is a fuel cell vehicle, in addition to the amount of stored power stored in the storage battery, the remaining amount of gaseous fuel such as hydrogen is acquired.

[0036] The position identifying unit 36 ​​identifies a position on the map data corresponding to each identification number acquired by the building information acquiring unit 32. Specifically, the position identifying unit 36 ​​identifies the position of a building on the map data based on the coordinate data of the building acquired by the building information acquiring unit 32. Here, the map data may be externally created and acquired from a server or the like, or map data previously stored in the storage 18 may be used.

[0037] The power supply request receiving unit 38 receives a power supply request from a user of the building. In the present embodiment, as an example, the power supply request receiving unit 38 receives a power supply request when the user of the building selects his / her home displayed on the screen of the mobile terminal 30. In addition, in the present embodiment, the power supply request receiving unit 38 is configured to prohibit an operation for requesting power supply when the vehicle supplying power to the building has a sufficient amount of stored power.

[0038] The display control unit 40 adds information about power supply from an external power source to the position on the map data identified by the position identification unit 36, and displays it on the mobile terminal 30. Specifically, the display control unit 40 displays on the map data buildings to which power is being supplied from the vehicle by the building information acquisition unit 32 and buildings to which power is not being supplied from the vehicle, distinguishing them from each other. In addition, the display control unit 40 changes the display mode on the map data for buildings to which power is being supplied from the vehicle, depending on at least one of the amount of stored power and the remaining fuel of the vehicle. Hereinafter, a display example of the mobile terminal 30 will be described with reference to FIG. 3.

[0039] 3, map data is displayed on the display screen of the mobile terminal 30. Here, as an example, the display control unit 40 of this embodiment is configured to display information on the mobile terminal 30 only during a disaster or power outage. For this reason, the power supply status of other buildings cannot be viewed even during normal times except during a disaster or power outage.

[0040] In Fig. 3, as an example, buildings H1 to H11 and buildings F1 to F6 are displayed on the map data. Buildings H1 to H11 correspond to the residences of residents in the block, and buildings F1 to F6 correspond to various facilities. In the following description, when there is no need to distinguish between buildings H1 to H11, they will simply be referred to as building H. Furthermore, when there is no need to distinguish between buildings F1 to F6, they will simply be referred to as building F.

[0041] The buildings H1 to H11 are displayed in the same shape and size for ease of viewing, but are not limited to this and may be displayed based on the outer shape of an actual house. Also, since this embodiment is configured to display only the power supply status of the house, the buildings F1 to F6 of the facility are displayed in the same display mode (display color).

[0042] Here, buildings H1, H4, H5, and H10 are displayed in a first display color, which is a relatively dark color. These buildings H are buildings to which power is not supplied from the vehicle. Specifically, these buildings H are buildings to which the vehicle is not connected and to which no other external power source is connected, or buildings to which the vehicle is connected but the amount of stored power in the vehicle's storage battery is zero or close to zero.

[0043] The buildings H3, H6, and H8 are displayed in a second display color that is slightly brighter than the first display color, and are hatched in FIG. 3 for convenience of explanation. These buildings are supplied with power from a vehicle, and the amount of power that can be supplied from the vehicle is low. The amount of power that can be supplied from the vehicle is calculated based on information acquired by the vehicle information acquisition unit 34. Specifically, if the vehicle supplying power to the building H is an electric vehicle, it is determined that the amount of power that can be supplied is low when the amount of power stored in the storage battery is equal to or less than a predetermined threshold. In addition, if the vehicle supplying power to the building H is a hybrid vehicle or a fuel cell vehicle, the amount of power that can be generated is calculated from the remaining amount of fuel (gasoline, hydrogen, etc.), and it is determined that the amount of power that can be supplied is low when the sum of the amount of power that can be generated and the amount of power stored in the storage battery is equal to or less than a predetermined threshold.

[0044] On the other hand, buildings H2, H7, H9, and H11 are displayed in a third display color that is brighter than the second display color. These buildings H are supplied with power from vehicles, and have a sufficient amount of power that can be supplied from the vehicle. Specifically, if the vehicle supplying power to building H is an electric vehicle, this is the case when the amount of stored power in the vehicle's storage battery is greater than a predetermined threshold. Also, if the vehicle supplying power to building H is a hybrid vehicle or a fuel cell vehicle, this is the case when the sum of the amount of power that can be generated and the amount of stored power in the storage battery is greater than a predetermined threshold.

[0045] As described above, the display control unit 40 reflects information about power supply from vehicles to the buildings H1 to H11 and displays it on the mobile terminal 30. The display mode is updated at predetermined time intervals.

[0046] Furthermore, when a power supply request is received by the power supply request receiving unit 38, the display control unit 40 displays a mark M corresponding to the power supply request on the map data for the building H of the user who has requested the power supply. In Fig. 3, the mark M is displayed at the position of the building H3. This is the mark that is displayed when the power supply request receiving unit 38 receives a power supply request from the user of the building H3.

[0047] (action) Next, the operation of this embodiment will be described.

[0048] (An example of display control processing) 4 is a flowchart showing an example of the flow of display control processing by the display control device 10. This power supply target switching processing is executed by the CPU 12 reading a program from the ROM 14 or storage 18, expanding it in the RAM 16, and executing it. Note that the display control processing described below is executed by the user starting a predetermined application via the mobile terminal 30 in a state in which the supply of commercial power has been stopped due to a power outage. Also, while the application is running, the display control processing is executed at predetermined time intervals.

[0049] 5, in step S102, the CPU 12 acquires information from each building H. Specifically, the CPU 12 acquires, by the function of the building information acquisition unit 32, the identification numbers of the buildings in the section and information related to power supply from the vehicle.

[0050] In step S104, the CPU 12 acquires information from each vehicle. Specifically, the CPU 12 acquires the remaining amount of fuel according to the type of vehicle through the function of the vehicle information acquisition unit .

[0051] The CPU 12 executes a subroutine of a display mode determination process in step S106, and displays the buildings H1 to H11 on the map data in the determined color. The display mode determination process will be described in detail later.

[0052] The CPU 12 determines whether or not a power supply request has been made in step S108. Specifically, when the CPU 12 receives a power supply request from a user of the building H through the function of the power supply request receiving unit 38, it determines that a power supply request has been made and proceeds to processing in step S110.

[0053] On the other hand, if the power supply request has not been received in step S108, the CPU 12 determines that there has been no power supply request. In this case, the determination in step S108 is negative, and the display control process is terminated.

[0054] The CPU 12 displays a mark M on the building for which the power supply request was accepted in step S110. Specifically, the CPU 12 uses the function of the display control unit 40 to display a mark M requesting power supply on the corresponding building on the map data.

[0055] (Display mode determination process) 5 is a flowchart showing an example of the flow of a display mode determination process by the display control device 10. This display mode determination process is executed by the CPU 12 reading a program from the ROM 14 or the storage 18, expanding it in the RAM 16, and executing it.

[0056] In step S202, the CPU 12 determines whether or not power is being supplied from the vehicle to the building H. Specifically, when power is being supplied from the vehicle based on the information acquired by the building information acquisition unit 32, the CPU 12 determines that power is being supplied and proceeds to processing in step S204. On the other hand, when power is not being supplied from the vehicle to the building H in step S202, the CPU 12 proceeds to processing in step S206, where the building H is set to the first display color. The buildings H1, H4, H5, and H10 are set to the first display color by the processing in step S206.

[0057] In step S204, the CPU 12 determines whether the amount of stored power of the vehicle is greater than a threshold. Specifically, if the amount of stored power of the vehicle acquired by the function of the vehicle information acquisition unit 34 is greater than a predetermined threshold, the CPU 12 proceeds to processing in step S210. At this time, if the vehicle is a hybrid vehicle or a fuel cell vehicle, the CPU 12 calculates the amount of stored power from the sum of the amount of power that can be generated and the amount of stored power in the storage battery.

[0058] On the other hand, if the amount of stored power of the vehicle is equal to or less than the predetermined threshold in step S204, the CPU 12 proceeds to the process of step S208, where the building H is set to the second display color in step S208. The buildings H3, H6, and H8 are set to the second display color by the process of step S208.

[0059] If the amount of stored power of the vehicle is greater than the predetermined threshold in step S204, the CPU 12 sets the buildings H2, H7, H9, and H11 to the third display color in the process of step S210.

[0060] As described above, in the display control device 10 of this embodiment, during a power outage, the function of the display control unit 40 causes information related to power supply from vehicles to be displayed on the mobile terminal 30. This allows residents to grasp information related to power supply from vehicles for each of the buildings H in the section simply by looking at the mobile terminal 30.

[0061] In particular, in this embodiment, residents can know buildings where power is not being supplied from vehicles to the building H simply by looking at the mobile terminal 30. In addition, even if power is being supplied to the building H, it is possible to know buildings where the amount of stored power in the vehicle is low. This allows electric vehicles and hybrid vehicles to be quickly directed to the building H that requires power supply.

[0062] In this embodiment, when a power supply request is received, a power supply request mark M is displayed on the map data. This allows residents to know the building H requesting power supply just by glancing at the mobile terminal 30.

[0063] Furthermore, in this embodiment, the power supply request receiving unit 38 prohibits the operation of a power supply request when the amount of stored power in the vehicle supplying power to the building H is sufficient. This allows only users who need power supply to request power supply, making it possible to prevent unauthorized use.

[0064] Furthermore, in this embodiment, since information can be displayed on the mobile terminal 30 only during a disaster or power outage, the power supply status of the building H cannot be seen under normal circumstances, and privacy can be ensured.

[0065] (Modification) Next, a display control device according to a modified example will be described. Note that the same components as those in the first embodiment are given the same reference numerals, and the description will be omitted as appropriate.

[0066] The display control device according to the modification includes the functional configuration shown in FIG. 2, similarly to the first embodiment, but the functions of the building information acquisition unit 32 and the display control unit 40 are partially different.

[0067] 6, the building information acquisition unit 32 acquires information on buildings H1 to H11, which are residences, as well as buildings F1 to F7, which are facilities. Specifically, the building information acquisition unit 32 in this embodiment acquires the operation status of facilities, including at least one of a power storage facility and a gas station, within the block.

[0068] Furthermore, the display control unit 40 displays on the map data the operation statuses of the facilities F1 to F7 acquired by the building information acquisition unit 32. Hereinafter, a display example of the mobile terminal 30 will be described with reference to FIG.

[0069] Buildings F1, F3 to F6 are displayed in the third display color, as are buildings H2, H7, H9, and H11. Therefore, these buildings F1 to F6 are powered by an external power source and have a sufficient amount of power available for supply.

[0070] On the other hand, building F2 is displayed in the second display color, as are buildings H3, H6, and H8. Therefore, building F2 is a building to which power is being supplied from the vehicle and the amount of power that can be supplied from the vehicle is low. In addition, building F2 is displayed with mark M, which indicates that the power supply request receiving unit 38 has received a power supply request from a user of building F2.

[0071] Here, the letter G is displayed on building F1, making it possible to visually recognize that building F1 is a gas station. Building F7 is displayed with an icon resembling a charging station, making it possible to visually recognize that building F7 is a power storage facility. Furthermore, as an example in this modification, the remaining amount of stored power is displayed numerically on building F7. For example, in FIG. 6, it can be seen that the remaining amount of stored power is 45%.

[0072] As described above, in this modification, the operation status of the building F7, which is the power storage facility, is displayed on the mobile terminal 30 by the display control unit 40. This allows residents to determine whether or not charging of vehicles is possible from the power storage facility.

[0073] In addition, in this modification, the operating status of the building F1, which is a gas station, is displayed on the display device. This allows residents to determine whether or not it is possible to refuel their vehicles with gasoline. Other operations are the same as those of the first embodiment.

[0074] Although the display control device 10 according to the embodiment and the modified example has been described above, it is needless to say that the present invention can be embodied in various forms without departing from the scope of the present invention. For example, in the above embodiment, when a power supply request is received, the mark M is displayed on the map data, but in addition to this, other marks may be displayed.

[0075] For example, when a signal indicating that power can be supplied is received from a user who owns a vehicle that can supply power, the vehicle that can supply power may be displayed on the map data. In this case, residents of a building that cannot supply power can directly request power supply from the owner of the vehicle that can supply power.

[0076] At this time, a reward for supplying power may be set in advance. For example, the reward may be a virtual currency such as electronic money, or points that can be used as part of the price of a product.

[0077] In the above embodiment, only the mark M is displayed on the building that has received the power supply request, but this is not limiting. For example, a power supply priority may be set in advance for the building, and the display mode of the mark M may be changed according to the power supply priority. As an example, a building with a high priority may be displayed in a brighter color than other marks M so that a high level of urgency can be understood. Also, the mark M may be displayed by flashing.

[0078] Furthermore, in the above embodiment, the first display color, the second display color, and the third display color are displayed according to the power supply status, but the present invention is not limited to this and other display modes may be used. For example, a display may be performed in which the colored area of ​​each building changes according to the remaining amount of stored power. In this case, for a building with 50% remaining stored power, only half of the building icon on the map data is colored, allowing the user to intuitively grasp the remaining amount of stored power.

[0079] Furthermore, in the above embodiment, a configuration in which the display is performed on the mobile terminal 30 as the display device has been described, but the present invention is not limited to this. For example, the display may be performed on a monitor installed in a building, or on a monitor installed in the cabin of a vehicle.

[0080] In addition, the processing executed by the CPU 12 by reading the software (program) in the above embodiment may be executed by various processors other than the CPU. In this case, examples of the processor include a PLD (Programmable Logic Device) such as an FPGA (Field-Programmable Gate Array) whose circuit configuration can be changed after manufacture, and a dedicated electric circuit such as an ASIC (Application Specific Integrated Circuit) which is a processor having a circuit configuration designed exclusively for executing a specific processing. The above processing may be executed by one of these various processors, or may be executed by a combination of two or more processors of the same or different types (for example, a plurality of FPGAs, and a combination of a CPU and an FPGA). The hardware structure of these various processors is, more specifically, an electric circuit that combines circuit elements such as semiconductor elements.

[0081] Furthermore, in the above embodiment, the storage 18 is the recording unit, but is not limited to this. For example, a non-transitory recording medium such as a CD (Compact Disk), a DVD (Digital Versatile Disk), or a USB (Universal Serial Bus) memory may be used as the recording unit. In this case, various programs may be stored in these recording media. [Explanation of symbols]
