The power failure information acquisition task 12 is activated by the control unit 10 when the countermeasure necessity determination task 15 is activated, and acquires the power failure information stored in the power distribution automation system 50. For example, the power information acquisition task 12 confirms whether data relating to “power failure” is stored in a predetermined database of the distribution automation system 50, and acquires the data when the corresponding data is stored.

  The storage unit (not shown) stores various data, programs, and tasks necessary for the power failure response necessity determination system 1.

  The storage unit stores a customer information database 13a such as information about the location of the customer and the equipment installed in the customer's house as the customer information storage means 13. As shown in FIG. 2, in the customer information database 13a, a location 132, contract information 133, used device information 134, and others 135 are stored for each customer ID 131 for identifying a customer. The location 132 stores the location (address) of the customer. The contract information 133 stores notes on the contract, for example, that a power failure is not possible because a ventilator is used and a backup power supply needs to be secured. The used device information 134 stores a memory address that stores information related to a device such as an electric device installed in a customer's house. Information regarding the device includes a device ID 1341, manufacturer name 1342, model number 1343, use information 1344, relief information 1345, and other 1346.

  The used device ID 1341 stores an identification number for identifying the device, the manufacturer name 1342 stores the manufacturer name of the device, and the model number 1343 stores the model number (product number) of the device. Yes. The usage information 1344 stores information related to the use of the device. The usage information 1344 allows each customer to register the usage status such as the usage time zone and timer setting time (reservation time) of each device through a homepage, a customer center, or the like. In addition, the usage information 1344 can acquire the usage status such as the usage time zone and power consumption of each device via the smart meter 41 and the distribution board 42 at each customer's house, and can be automatically registered. The relief information 1345 stores relief information for each customer of the device, and stores that fact when the customer prepares a backup power source.

  For example, data as shown in FIG. 3 is stored as an example of the used device information 134 of a device installed in a certain customer's house. About the refrigerator A, it has memorize | stored that it is always using at preset temperature OO degreeC as the usage information 1344. FIG. As for the tropical fish pump B, it is memorized that it is always used as the usage information 1344, and it is memorized as “relief information 1345” that “there is an in-house power generator, power failure is possible for 3 hours or less, and relief is necessary for 3 hours or more”. doing. The TV recording device C stores “July 21 15: 00 to 16:00 (recording reservation)” as usage information 1344. Furthermore, the rice cooker D is stored as “Monday to Friday 13:00 (reserved rice cooked), Saturday and Sunday 12:00 (reserved rice cooked)” as usage information 1344.

  Further, the storage unit stores a device information database 14a as the device information storage means 14 such as an operable time at the time of a power failure of the device and a countermeasure. As shown in FIG. 4, in the device information database 14a, a manufacturer name 142, a model number 143, an operable time 144 during power failure, and other 145 are stored for each device ID 141 that identifies a device. In the operable time 144 at the time of a power failure, a memory address that stores the operable time (time required for handling) at the time of a power failure of each device is stored. Here, the operable time stores a time that can be operated by the built-in battery, a time that can maintain a predetermined temperature due to residual heat, and the like. Information on the operable time includes a season / temperature 1441, an operable time 1442, and a coping method 1443.

  For example, data as shown in FIG. 5 is stored as an example of the device operable time information 144 at the time of a power failure. Refrigerator A is “spring (temperature 10 ° C. to 25 ° C.)” as the season / temperature 1441, “3 hours” as the operable time 1442, and “rapid cooling after power outage is required (when 3 hours or more)” as the countermeasure 1443 Also, “Summer (temperature 25 ° C or higher)” as the season / temperature 1441, “2 hours” as the operable time 1442, “Caution is necessary because the food rots, quick cooling after power failure is required (2 hours or more)” In the case of) ”. The operable time of the refrigerator A indicates a time during which the temperature in the refrigerator can maintain a predetermined temperature in a state where the supply of power from the commercial power supply is stopped. The tropical fish pump B stores “year” as the season / temperature 1441 and “0 hour” as the operable time 1442. Also, the TV recording device C has “yearly” as the season / temperature 1441, “1 hour” as the operable time 1442, and “there is a built-in battery, and the time needs to be reset (in the case of 1 hour or more)” as the countermeasure 1443. I remember it. Furthermore, the rice cooker D stores “yearly” as the season / temperature 1441, “0 hour” as the operable time 1442, and “requires switching on again” as the countermeasure 1443.

  The countermeasure necessity determination task 15 as the countermeasure necessity determination means extracts the consumers included in the power outage area based on the power outage information acquired from the distribution automation system 50, the customer information database 13a, and the equipment information database 14a. Then, it is a program having a function of acquiring a coping method when the necessity of coping with the power outage is determined for each device at the customer's home, and coping is necessary, and performs processing based on the flowchart shown in FIG. . For example, the coping necessity determination task 15 is activated when the power failure coping necessity determination system 1 is activated via the mobile phone 20 or the PC 30, and (b) a contract number, a password, etc. (customer mode), (b) ) When an address, a postal code, etc. (general mode) are input, the controller 10 is activated. Here, in (a) the customer mode, information that can identify the customer is input, and (b) in the general mode, information that can specify an area is input.

  When the countermeasure necessity determination task 15 is activated, as shown in FIG. 6, first, the power failure information acquisition task 12 is activated to acquire power failure information from the distribution automation system 50 (step S1).

  Next, it is determined whether or not it is within the power outage area based on the input determination condition (step S2). If it is outside the power outage area (in the case of “NO”), a message indicating that it is out of the power outage area (area where there is no power outage) is output and the processing of this task is terminated (step S3).

  If it is in the power outage area (in the case of “YES”), the process proceeds to step S4 and common information is acquired (step S4). Here, the common information is the business situation of public institutions such as banks and hospitals, and commercial facilities such as supermarkets, shopping streets, and restaurants. The business situation of this public institution or commercial facility is stored in advance in the database. For example, each public institution or commercial facility remembers that “it has private power generation facilities, so it can operate for 4 hours even during a power failure” or “temporarily closed by increasing the closing time during a power failure” . In addition, if all the public institutions and commercial facilities of the same type are not operating in the power outage area, the nearest public institution or commercial facility in operation (no power outage) is acquired.

  Next, it is determined whether or not the customer himself / herself (step S5). That is, it is determined whether an appropriate contract number and password are input as determination conditions, that is, whether or not the customer is the customer. If it is not the customer himself (in the case of “NO”), the processing of this task is terminated.

  If it is the customer itself (in the case of “YES”), the process proceeds to step S6, where all the devices of the customer are acquired from the customer information database 13a (step S6), and the first device is acquired from among them. (Step S7).

  Next, it is determined whether or not the device needs to be dealt with in the event of a power failure (step S7). Here, it is determined whether or not it is necessary to deal with a power failure, from the acquired usage information 1344, season / temperature 1441, and operable time 1442 of the device, the usage time is included in (A) the predicted power failure time (power failure If there is a use reservation at the time of occurrence or after a power failure), (B) if the predicted power failure time is longer than the operable time, it is determined that action is required.

  If no action is required (“NO”), the process proceeds to step S10. When a countermeasure is required (in the case of “YES”), the process proceeds to step S9, and a countermeasure is acquired from the rescue information 1345 and the countermeasure 1443.

  Next, it is determined whether or not all devices are finished (step S10). If not finished (in the case of “NO”), the next device is acquired in step S11, and the process proceeds to step S8. The process is repeated until all devices are finished. When all the devices are finished (in the case of “YES”), the processing of the necessity / unnecessity determination task 15 is finished.

  The countermeasure necessity notification task 16 as a countermeasure necessity notification means has a function of notifying the consumer of necessity of countermeasures and countermeasures in each device for each consumer house determined by the countermeasure necessity determination task 15. It is a program. The countermeasure necessity notification task 16 is started by the control unit 10 after the countermeasure necessity determination task 15 is completed.

  Next, the countermeasure necessity determination process, the countermeasure necessity notification process and the action in the power failure countermeasure necessity determination system 1 having such a configuration will be described.

  Here, for example, as shown in FIG. 7, banks No. 1 to No. 3 are provided in the power distribution network, the No. 1 bank is connected to customer houses and banks, and the No. 2 bank is connected to restaurants and supermarkets. A case where a customer's house is connected to the No. 3 bank will be described. At this time, it is assumed that banks 1 to 3 are blackout areas. The power outage will be sent to the distribution automation system 50 at a power outage start time of July 21 (Thursday) at 12:00, a recovery expected time of July 21 (Thursday) at 14:30, and a power outage area (power outage area) Data is stored in the ○○ and □□ regions, and the cause is currently being investigated and the person in charge is moving to the site for recovery.

  A case where the customer himself / herself in the power outage area activates the countermeasure necessity determination task 15 will be described.

  First, the customer himself / herself starts the power failure coping necessity determination system 1 via the mobile phone 20 or the PC 30, inputs a contractor number and a password as judgment conditions, and starts the coping necessity judgment task 15. At this time, in step S1 of the flow shown in FIG. 6, the power failure information acquisition task 12 is activated to acquire power failure information from the distribution automation system. Then, in step S2, it is determined that the area is within the power outage area ("YES"), and common information is acquired in step S4. Here, as common information, the supermarket in the power outage area is a backup power supply (emergency power supply) for up to 4 hours after the power outage (up to 16:00), and the refrigerator is not required (operable). The bank will be closed if 4 hours or more have passed, and the bank will be able to use the ATM with a backup power source (emergency power) until 12 hours after the power failure (up to 24:00). Acquired that there is no power supply (emergency power supply) and that the business is suspended.

  Next, in step S5, it is determined that the user is the customer himself ("YES"). And the process of step S8, S9 is repeated about all the apparatuses of the said consumer from the consumer information database 13a. That is, it is determined for all devices whether or not the power outage needs to be dealt with, and if a measure is needed, a coping method is acquired. That is, for each device, (A) the predicted power outage time (from the power outage start time 12:00 to the recovery expected time 14:30) includes the use time (used during a power outage or reserved for use after a power outage), (B ) It is determined whether or not the predicted power outage time (2 hours 30 minutes) is longer than the operable time.

  Specifically, when the apparatus shown in FIG. 3 and FIG. 5 is provided, the refrigerator A uses the usage information 1344, the season / temperature 1441, and the operable time 1442 to determine (A) the predicted power outage time ( Use time (from 00:00 to 24:00 every day) is included in the power outage start time from 12:00 to the expected recovery time of 14:30, and (B) the predicted power outage time (2 hours 30 minutes) is operable time (summer (Temperature 25 ° C. or higher) is longer than 2 hours), so it is determined that countermeasures are required. And from coping method 1443, when the power failure time exceeds 2 hours, or when the recovery time exceeds 14:00, the coping method that food needs to be rotted is acquired.

  In addition, the tropical fish pump B includes (A) a predicted power outage time (from a power outage start time 12:00 to a recovery expected time 14:30) that includes the use time (every day from 0:00 to 24:00), (B) Since the predicted power outage time (2 hours 30 minutes) is longer than the operable time (0 hours), it is determined that no action is required. Then, it can be seen from the relief information 1345 that the self-generator can save for 3 hours or less and no response is required until 15:00, but if it is 3 hours or more, relief is necessary. Similarly, in the TV recording device C, (A) the predicted power outage time (from the power outage start time 12:00 to the recovery expected time 14:30) includes the usage time (there is a recording reservation after the recovery expected time), (B ) Since the predicted power outage time (2 hours 30 minutes) is longer than the operable time (1 hour), it is determined that countermeasures are required. Then, from coping method 1443, a coping method is obtained that the operation is possible for one hour by the built-in battery, but after that, the clock needs to be reset. Furthermore, the rice cooker D includes (A) the predicted power outage time (from the power outage start time 12:00 to the recovery expected time 14:30), including the usage time (there is a rice cooking reservation), and (B) the predicted power outage time (2 hours) 30 minutes) is longer than the operable time (0 hours), so it is determined that countermeasures are required. And from coping method 1443, the coping method that it is necessary to switch on again is acquired, and because there is a rice cooking reservation at 13:00, rice is not cooked and it is necessary to switch on again after a power failure Recognize.

  In this way, the necessity / unnecessity determination task 15 determines the necessity / unnecessity of dealing with the power outage for all the devices of the customer, and if the countermeasure is necessary, the countermeasure is acquired.

  Subsequently, the countermeasure necessity notification task 16 is activated, and the consumer is notified of the necessity of countermeasures for each device acquired by the countermeasure necessity determination task 15 and the countermeasure method. At this time, it is displayed in a format as shown in FIG. In other words, the power outage information, which is a common matter, the business situation at the time of a power outage in a nearby public institution / commercial facility, and the status of the equipment at the time of the power outage, which is information unique to the customer, are notified.

  Next, a case where a third party such as a customer outside the power outage area activates the coping necessity determination task 15 will be described.

  First, the third party activates the power failure coping necessity determination system 1 via the mobile phone 20 or the PC 30, inputs the address and zip code of the target area as the judgment condition, and starts the coping necessity judgment task 15. Is done. At this time, in step S of the flow shown in FIG. 6, the power failure information acquisition task 12 is activated and power failure information is acquired. Then, in step S2, it is determined that the area is within the power outage area ("YES"), and common information is acquired in step S4.

  Next, in step S5, it is determined that the user is not the customer himself (“NO”), and the processing of the countermeasure necessity determination task 15 is ended.

  Subsequently, the countermeasure necessity notification task 16 is started, and only the common information not including the information unique to each customer acquired by the countermeasure necessity determination task 15 is notified to the third party. At this time, it is displayed in a format as shown in FIG. In other words, only the power outage information, which is a common matter, and the business situation at the time of power outage in nearby public institutions / commercial facilities are notified.

  As described above, according to the power failure coping necessity determination system 1, it is determined whether or not coping with a power failure is necessary for each device in a customer's house, and when a coping is necessary, a coping method is acquired. There is no need to determine whether or not to deal with each device installed in the house. In other words, since human determination is not required, it is possible to prevent erroneous determination and forgetting determination and appropriately deal with each device. Further, since it is determined whether or not each device needs to be dealt with based on the predicted power outage time, the season / temperature, the presence / absence of a backup power supply, the presence / absence of use, the presence / absence of use reservation, etc., the determination can be made accurately.

  In addition, when a third party other than the consumer activates the coping necessity determination task 15, it is possible to obtain information on the influence of the power failure only for public institutions and commercial facilities in the power failure area, and the customer-specific personal information Will not be known to any third party.

  In addition, since information related to equipment at the customer's home can be automatically acquired via the smart meter 41 and the distribution board 42, appropriate determination based on the latest information can always be performed.

  Furthermore, since the necessity of coping in each device for each customer house determined by the coping necessity judgment task 15 and the coping method are notified to the customer, the consumer can easily deal with the coping necessity and coping method. Can be obtained. Since each device can be appropriately dealt with based on the information acquired in this manner, the influence of the power failure can be minimized.

  Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, in the above embodiment, a case where a power outage has occurred in the distribution network has been described. However, for planned power outages and past power outages, it is necessary to determine whether or not the power outage needs to be dealt with and to take action. Of course, you can get a workaround.

  In addition, the customer himself / herself has explained that the power failure coping necessity determination system 1 is started and the determination condition is input via the mobile phone 20 or the PC 30, but the following may be performed. That is, when a power failure occurs, the power failure information acquisition task 12 acquires power failure information such as the power failure area and the predicted power failure time stored in the distribution automation system 50, and displays the power failure area on the map. Then, when a house or a region is selected on the map, the countermeasure necessity determination task 15 is activated using the selected area as a determination condition. At this time, if you have selected a house, if you are the customer of the house (if an accurate contract number, password, etc. are entered), you will be in the customer mode, otherwise in the general mode to start.

  Furthermore, when the person in charge of the electric power company starts up in the administrator mode, the countermeasure necessity determination task 15 collectively deals with all the devices of all the customers included in the power outage area. The necessity may be determined, and if a countermeasure is required, a countermeasure may be acquired. Then, the necessity / unnecessity notification task 16 may be used to notify each customer of the necessity of coping with each device and the coping method.
