[0047] The device estimation unit 64 estimates the type of home appliance connected to each power outage-resistant outlet based on the first measurement data acquired by the data acquisition unit 62 and the estimation information stored in the storage unit 63.

[0048] The device estimation unit 64 estimates the type of home appliance connected to each incompatible outlet based on the second measurement data acquired by the data acquisition unit 62 and the estimation information stored in the storage unit 63.

[0049] The power estimation unit 65 estimates the total power consumed by multiple power outage-compatible outlets during a power outage, based on the estimation results from the equipment estimation unit 64. The power estimation unit 65 also estimates, based on the estimation results from the equipment estimation unit 64, whether there are any home appliances that will switch their connection destination from one of the non-compatible outlets to one of the power outage-compatible outlets during a power outage, and then estimates the total power consumed by multiple power outage-compatible outlets during a power outage.

[0050] The power estimation unit 65 estimates the usable time of the emergency power supply 12 during a power outage based on the total power consumed by multiple power outage-resistant outlets during a power outage and the power that can be supplied to the emergency power supply 12 during a power outage.

[0052] Figure 3 is an explanatory diagram showing an example of a home appliance prediction condition table as power consumption information stored in the memory unit 63 of Figure 2. The memory unit 63 has a home appliance prediction condition table like the one shown in Figure 3 pre-stored in it.

[0053] The home appliance forecasting conditions table is a table that shows the relationship between the type of home appliance, continuous operating time, standby power, power consumption, operating time period, number of on / off cycles per day, and power consumption fluctuations. The home appliance forecasting conditions table is created in advance based on the specifications of each home appliance.

[0054] Figure 4 is an explanatory diagram showing an example of a power consumption trend graph of the refrigerator 46 as power consumption information stored in the memory unit 63 of Figure 2.

Figure 6 is an explanatory diagram showing an example of a power consumption trend graph for a rice cooker 43, which is stored in the memory unit 63 of Figure 2 as power consumption information.

[0056] Thus, the memory unit 63 has pre-stored power consumption information for various home appliances. By comparing the first and second measurement data, which are actually measured data, with the power consumption information, the type of home appliance connected to each outlet is estimated.

[0057] Furthermore, power consumption information may be generated using supervised machine learning, which utilizes measurement results of power consumption when multiple products from multiple manufacturers are actually in operation for each of several types of home appliances.

[0059] The equipment estimation unit 64 estimates the type of household appliance that uses at least one of tap water and gas by using a meter-related table.

[0060] Furthermore, water usage information may include not only whether or not tap water was used, but also information on the temporal fluctuations in tap water usage by multiple household appliances. Similarly, gas usage information may include information on the temporal fluctuations in gas usage by multiple household appliances.

[0061] Figure 8 is an explanatory diagram showing an example of a lifestyle table as lifestyle information stored in the memory unit 63 of Figure 2. The lifestyle table is a table that shows the relationship between the time of day and the typical lifestyle of the residents.

[0062] Furthermore, the following information can be cited as an example of the information regarding the order in which home appliances are used, which is stored in the memory unit 63.

[0063] • Rice cookers are used before dishwashers. • Dishwashers are used after rice cookers.

[0064] The appliance estimation method according to Embodiment 1 includes a data acquisition step and an appliance estimation step. The data acquisition step is a step of acquiring first measurement data. The appliance estimation step is a step of estimating the type of appliance connected to the power outage-resistant outlet based on the first measurement data acquired in the data acquisition step and estimation information including power consumption information.

[0065] Furthermore, in the data acquisition step, a second set of measurement data is acquired. Then, in the device estimation step, the type of home appliance connected to the incompatible outlet is estimated based on the second set of measurement data acquired in the data acquisition step and the estimated information.

[0066] Furthermore, the appliance estimation method includes a power estimation step. The power estimation step estimates the power consumed by a power outage-resistant outlet during a power outage, based on the estimation results from the appliance estimation step.

[0067] In addition, water usage data and gas usage data are acquired during the data acquisition step.

[0068] In such appliance estimation systems and methods, the type of appliance connected to each power outage-resistant outlet is estimated based on first measurement data, which is the actual power consumption data for each power outage-resistant outlet, and estimation information that includes power consumption information.

[0069] Therefore, it is possible to estimate which household appliances will be used during a power outage and to easily estimate the amount of electricity consumed during a power outage.

[0070] This allows for the notification of household appliances that are deemed unlikely to be needed during a power outage and are connected to any power-saving outlets, enabling residents to take preventative measures in advance.

[0071] Furthermore, if household appliances that should receive power during a power outage are not connected to power-saving outlets, this can be communicated to residents in advance so they can take appropriate action.

[0072] Furthermore, if it is determined that the amount of electricity consumed during a power outage will exceed the amount of electricity that can be supplied, this can be communicated to residents in advance so that they can take appropriate measures.

[0073] Furthermore, the power estimation unit 65 estimates the power consumed by multiple power outage-resistant outlets during a power outage based on the estimation results from the equipment estimation unit 64. This allows for more accurate and smoother estimation of the power consumed by multiple power outage-resistant outlets during a power outage.

[0074] Furthermore, based on the second measurement data, which represents the actual power consumption at each non-compatible outlet, and the estimated information, the type of home appliance connected to the non-compatible outlet is estimated. Therefore, by referring to the home appliances connected to multiple non-compatible outlets, it is possible to more accurately estimate which home appliances will be used during a power outage. This allows for a more accurate estimation of the power consumed during a power outage.

[0075] Furthermore, the power estimation unit 65 estimates, based on the estimation results from the equipment estimation unit 64, whether or not there are any home appliances that can switch their connection destination from a non-compatible outlet to a power outage-compatible outlet during a power outage, and then estimates the power consumed during a power outage. This allows for a more accurate and smoother estimation of power consumed during a power outage.

[0076] Furthermore, the data acquisition unit 62 acquires water usage data. The estimated information includes water usage information. Therefore, the type of household appliance can be estimated more accurately.

[0077] Furthermore, the data acquisition unit 62 acquires gas usage data. The estimated information includes gas usage information. Therefore, the type of home appliance can be estimated more accurately.

[0078] Furthermore, the estimated information includes timing information. Therefore, it is possible to estimate the type of home appliance more accurately.

[0079] Furthermore, the timing information includes lifestyle information. Therefore, it is possible to more accurately estimate the type of home appliance being used.

[0080] Furthermore, the timing information includes information about the usage sequence of at least two of the various types of home appliances. Therefore, it is possible to more accurately estimate the type of home appliance.

[0081] The appliance estimation program of Embodiment 1 is a program that causes a computer to execute the appliance estimation method of Embodiment 1.

[0082] Furthermore, the recording medium of Embodiment 1 is a computer-readable recording medium that stores a home appliance estimation program that causes a computer to execute the home appliance estimation method of Embodiment 1.

[0083] Furthermore, the power source for the emergency power supply 12 is not limited to the EV 13; it may also be a hybrid vehicle, an emergency generator, or the like.

[0084] Furthermore, there are no particular limitations on the number of electrical outlets, the number of electrical appliances, or the types of electrical appliances provided in each dwelling unit.

[0085] Furthermore, the home appliance estimation system of Embodiment 1 is applicable not only to apartment buildings but also to detached houses, offices where multiple home appliances are used, and so on.

[0086] Furthermore, each function of the connected device estimation device 60 in Embodiment 1 is realized by a processing circuit. Figure 9 is a configuration diagram showing a first example of a processing circuit that realizes each function of the connected device estimation device 60 in Embodiment 1. The processing circuit 100 in the first example is dedicated hardware.

[0089] Processor 201 can include, for example, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), a microprocessor, a microcontroller, or a DSP (Digital Signal Processor).

[0090] In the processing circuit 200, each function of the connected device estimation device 60 is realized by software, firmware, or a combination of software and firmware. The software and firmware are written as programs and stored in memory 202. The processor 201 realizes each function by reading and executing the programs stored in memory 202.

[0091] The program stored in memory 202 can be said to cause the computer to execute the procedures or methods of each of the parts described above. Here, memory 202 refers to non-volatile or volatile semiconductor memory such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable Read Only Memory), and EEPROM (Electrically Erasable and Programmable Read Only Memory).

[0092] Furthermore, some of the functions of the above-mentioned parts may be implemented using dedicated hardware, while others may be implemented using software or firmware.

[0093] Thus, the processing circuit can realize the functions of each of the above-mentioned parts through hardware, software, firmware, or a combination thereof.
