[0003] [Patent Document 1] JP 2016-115055 A Summary of the Invention [Problem to be solved by the invention]

[0004] In order to identify the temperature of the user's living environment and the operating status of home appliances, it is conceivable to incorporate various sensors such as a temperature sensor into a power supply device that supplies power from an outlet such as a power strip to an electrical appliance. However, this causes a problem in that the power supply device heats up due to the power it supplies to the electrical appliance, making it impossible to accurately measure the temperature of the user's living environment.

[0005] The present invention has been made in consideration of these points, and has an object to reduce measurement errors in the temperature of a user's living environment. [Means for solving the problem]

[0006] An information processing device according to a first aspect of the present invention has a plug for connection to an outlet and one or more sockets for connection to the plug of an electrical device, and has an identification unit that identifies the amount of power supplied to the one or more electrical devices connected to the socket of a power supply device that supplies power supplied from the outlet to the one or more electrical devices connected to the socket, and a calculation unit that calculates a correction value for correcting the temperature of the power supply device measured by the power supply device to the temperature of a location where the power supply device is installed based on the amount of power identified by the identification unit.

[0007] The identification unit may identify an amount of power supplied per unit time to the one or more electrical devices connected to the socket, and identify an elapsed time from when power was supplied to the one or more electrical devices to the current time, and the calculation unit may calculate the correction value based on the amount of power supplied per unit time identified by the identification unit and the elapsed time.

[0008] The identification unit may refer to a memory unit in which a cumulative value of the amount of power supplied to the one or more electrical devices at a predetermined time interval and the time at which the cumulative value was measured are stored in association with each other, identify a cumulative value of the amount of power supplied to the one or more electrical devices connected to the socket during a predetermined period from a time a predetermined time before the current time to the current time, and identify the amount of power supplied per unit time to the one or more electrical devices based on the predetermined period and the identified cumulative value.

[0009] The calculation unit may refer to a memory unit that stores multiple ranges of the amount of power supplied per unit time in association with relationship information indicating the relationship between the elapsed time corresponding to the ranges and the correction value, identify relationship information associated with the range corresponding to the amount of power supplied per unit time identified by the identification unit, and calculate the correction value based on the identified relationship information and the elapsed time identified by the identification unit.

[0010] The identification unit may identify the elapsed time since the plug of the power supply device was connected to the outlet, and the calculation unit may calculate the correction value when the socket is in an unloaded state in which no electrical equipment is connected to the socket for a predetermined period of time, based on relationship information indicating the relationship between the elapsed time in the unloaded state and the correction value and the elapsed time identified by the identification unit.

[0011] The information processing device may further include a communication unit that communicates with an external device, an acquisition unit that acquires temperature information indicating the temperature of the power supply device, and a transmission unit that transmits to the external device information indicating the temperature of a location where the power supply device is installed based on the temperature indicated by the temperature information acquired by the acquisition unit and the correction value calculated by the calculation unit.

[0012] An information processing method according to a second aspect of the present invention includes the steps of: executing a computer, determining an amount of power supplied to one or more electrical devices connected to the socket of a power supply device having a plug for connecting to an outlet and one or more sockets for connecting to the plug of an electrical device, and supplying power supplied from the outlet to the one or more electrical devices connected to the socket; and calculating a correction value based on the determined amount of power for correcting the temperature of the power supply device measured by the power supply device to the temperature of a location where the power supply device is installed.

[0013] A program according to a third aspect of the present invention causes a computer to function as an identification unit that identifies the amount of power supplied to one or more electrical devices connected to the socket of a power supply device having a plug for connecting to an outlet and one or more sockets for connecting to the plug of an electrical device, and that supplies power supplied from the outlet to the one or more electrical devices connected to the socket, and a calculation unit that calculates a correction value for correcting the temperature of the power supply device measured by the power supply device to the temperature of a location where the power supply device is installed based on the amount of power identified by the identification unit.

[0016] [Overview of information processing device 10] Fig. 1 is a diagram for explaining an overview of a smart plug 1. The smart plug 1 is a power supply device that is installed in a user's living environment, has a plug 2 that connects to an outlet for supplying power, and a socket 3 that connects to the plug of an electrical device, and supplies power supplied from the outlet to the electrical device connected to the socket 3. Note that, in Fig. 1, the smart plug 1 is provided with one socket 3, but is not limited to this, and multiple sockets 3 may be provided.

[0017] The smart plug 1 has various sensors such as an illuminance sensor 4, a human presence sensor 5, a power meter 6, and a temperature sensor 7, as well as an information processing device 10, and has the function of notifying the outside world of the indoor situation, which is the user's living environment, based on the detection status of the various sensors.

[0018] The information processing device 10 of the smart plug 1 notifies a server (not shown) that manages the indoor conditions, including the lighting status of the lights installed in the room detected by the illuminance sensor 4, the presence of people in the room detected by the human presence sensor 5, the power consumption by the electrical appliances connected to the socket 3 measured by the power meter 6, and the indoor temperature detected by the temperature sensor 7.

[0019] However, the smart plug 1 generates heat due to the power it supplies to the electrical device connected to the socket 3, and the temperature detected by the temperature sensor 7 becomes higher than the temperature around the smart plug 1. In response to this, the information processing device 10 calculates a correction value for correcting the temperature measured by the temperature sensor to the temperature of the location where the smart plug 1 is installed, based on the amount of power supplied by the smart plug 1 to the electrical device. In this way, the smart plug 1 can correct the temperature measured by the temperature sensor using the correction value, and reduce measurement errors in the indoor temperature, which is the living environment of the user where the smart plug 1 is installed.

[0020] [Functional configuration of information processing device 10] Next, a description will be given of the functional configuration of the information processing device 10. As described above, the information processing device 10 notifies the server of situation information indicating the indoor situation detected by various sensors, but the following description will focus on the function of notifying the temperature in the room where the smart plug 1 is installed.

[0021] 2 is a diagram showing a functional configuration of the information processing device 10. The information processing device 10 has a communication unit 11, a storage unit 12, and a control unit 13. The communication unit 11 is a communication interface for transmitting and receiving data to and from a server that manages situation information indicating the situation in the room in which the smart plug 1 is installed.

[0022] The storage unit 12 is a storage medium that stores various data, and includes a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk, etc. The storage unit 12 stores a program executed by the control unit 13. The storage unit 12 stores a program that causes the control unit 13 to function as an identifying unit 131, an acquiring unit 132, a calculating unit 133, and a transmitting unit 134.

[0023] Furthermore, the memory unit 12 stores measurement history information indicating a measurement history of the amount of power supplied by the smart plug 1 to the electrical device, measured by the power meter 6. Fig. 3 is a diagram showing an example of the measurement history information. As shown in Fig. 3, the measurement history information is information that associates measurement result information indicating a cumulative value of the amount of power supplied by the smart plug 1 to the electrical device, measured by the power meter 6, with the measurement time of the cumulative value. For example, the memory unit 12 is provided with a memory area for storing measurement history information for a predetermined number of times (e.g., 12 times), and a maximum of the predetermined number of times of measurement result information is stored.

[0024] The control unit 13 is, for example, a CPU (Central Processing Unit). The control unit 13 executes a program stored in the storage unit 12, thereby functioning as a specification unit 131, an acquisition unit 132, a calculation unit 133, and a transmission unit .

[0025] The identifying unit 131 acquires, from the power meter 6, measurement result information indicating a measurement result of the amount of power supplied to the electrical device connected to the socket 3. For example, the identifying unit 131 acquires, from the power meter 6, measurement result information indicating a cumulative value of the amount of power supplied to the electrical device connected to the socket 3. For example, when the plug 2 of the smart plug 1 is connected to an outlet, the power meter 6 measures the amount of power supplied by the smart plug 1 to the electrical device connected to the socket 3. The power meter 6 outputs, to the information processing device 10, measurement result information indicating a cumulative value of the amount of power supplied to the electrical device.

[0026] The identifying unit 131 acquires measurement result information from the power meter 6 at a first time interval (e.g., 5 minutes). Upon acquiring the measurement result information, the identifying unit 131 identifies whether the smart plug 1 is in a loaded state or an unloaded state. The loaded state is a state in which the smart plug 1 supplies power to an electric device connected to the socket 3. The unloaded state is a state in which no electric device is connected to the socket 3 or the power of the electric device connected to the socket 3 is turned off and the smart plug 1 does not supply power to the electric device.

[0027] For example, the identifying unit 131 determines that the smart plug 1 is in an unloaded state when at least one of the following conditions is met: (1) no measurement history information is stored in the memory unit 12, (2) the difference between the measurement time included in the latest measurement history information stored in the memory unit 12 and the current time is greater than a predetermined period (e.g., one hour), or (3) the difference between the accumulated value of the power amount in the latest measurement history information within a predetermined period stored in the memory unit 12 and the accumulated value of the power amount in the oldest measurement history information is zero. When the identifying unit 131 has not determined that the smart plug 1 is in an unloaded state, it determines that the smart plug 1 is in a loaded state.

[0028] When the smart plug 1 is in a loaded state, the identifying unit 131 identifies the amount of power supplied to one or more electric devices connected to the socket 3 of the smart plug 1. When the smart plug 1 is in a loaded state, the identifying unit 131 identifies the amount of power supplied per unit time (e.g., one hour) to the one or more electric devices connected to the socket 3.

[0029] Specifically, the identifying unit 131 refers to the storage unit 12, which associates an accumulated value of the amount of power supplied to one or more electric devices at a first time interval with the measurement time at which the accumulated value was measured and stores the associated accumulated value as measurement history information, and identifies an accumulated value of the amount of power supplied to one or more electric devices connected to the socket 3 during a predetermined period from a time that is a second time (e.g., one hour) before the current time to the current time. Then, the identifying unit 131 identifies the amount of power supplied per unit time to the one or more electric devices based on the predetermined period and the identified accumulated value. Here, the second time is assumed to be longer than the first time.

[0030] For example, the identifying unit 131 identifies the latest measurement history information and the oldest measurement history information stored in the memory unit 12, and identifies the time difference between the measurement time of the latest measurement history information and the measurement time of the oldest measurement history information as an on-load elapsed time, which is the elapsed time from when power was supplied to one or more electrical devices to the current time. The identifying unit 131 also calculates the power consumption within the period by subtracting the accumulated value of the power amount included in the oldest measurement history information from the accumulated value of the power amount included in the latest measurement history information. The identifying unit 131 identifies the supplied power amount, which is the amount of power supplied per unit time to one or more electrical devices, by dividing the power consumption within the period by the identified on-load elapsed time.

[0031] Here, the storage unit 12 stores a maximum of a predetermined number of measurement result information (e.g., 12 times), and the measurement result information is stored in the storage unit 12 at a first time interval (e.g., 5 minutes), so that an upper limit value of the elapsed time is set based on the predetermined number of measurement times and the first time interval. The identification unit 131 identifies an elapsed time equal to or less than the upper limit value.

[0032] When smart plug 1 is in an unloaded state, identifying unit 131 identifies the elapsed time from when plug 2 of smart plug 1 is connected to an outlet as the unloaded elapsed time. For example, identifying unit 131 identifies the elapsed time from the measurement time of the oldest measurement history information among the measurement history information stored in memory unit 12 and having a measurement time newer than a second time before the current time to the current time as the unloaded elapsed time.

[0033] When the identifying unit 131 identifies the amount of power supply and the elapsed time, it sets the time when the measurement result information was acquired as the measurement time, and associates the acquired measurement result information with the measurement time and stores them as measurement history information in the storage unit 12. When a predetermined number of pieces of measurement history information have been stored in the storage unit 12, the identifying unit 131 deletes the oldest measurement history information, and associates the acquired measurement result information with the measurement time and stores them as measurement history information in the storage unit 12.

[0034] The acquiring unit 132 acquires temperature information indicating the temperature of the smart plug 1. Specifically, the acquiring unit 132 acquires, from the temperature sensor 7 provided in the smart plug 1, temperature information indicating the temperature of the smart plug 1 measured by the temperature sensor 7.

[0035] The calculation unit 133 calculates a temperature correction value, which is a correction value for correcting the temperature indicated by the temperature information acquired by the acquisition unit 132 to the temperature of the location where the smart plug 1 is installed, based on the amount of power identified by the identification unit 131. For example, the calculation unit 133 calculates the temperature correction value based on the amount of supplied power, which is the amount of power supplied per unit time identified by the identification unit 131, and the elapsed time.

[0036] For example, the memory unit 12 stores a table for identifying relationship information that associates the state of the smart plug 1 with multiple ranges of the amount of power supplied, which is the amount of power supplied per unit time, and relationship information indicating the relationship between the elapsed time corresponding to the range and the temperature correction value.

[0037] Here, the relationship between the amount of supplied power, the elapsed time, and the temperature correction value will be described. Fig. 4 is a diagram showing the relationship between the amount of supplied power, the elapsed time, and the temperature correction value. Curves W1, W2, and W3 show the relationship between the elapsed time and the temperature correction value when the amount of supplied power is the first amount of supplied power, the second amount of supplied power, and the third amount of supplied power. The second amount of supplied power is larger than the first amount of supplied power, and the third amount of supplied power is larger than the second amount of supplied power.

[0038] As shown in Fig. 4, the temperature correction value for the same elapsed time increases as the amount of power supplied increases. The temperature correction value also increases as time passes. However, once the elapsed time exceeds a predetermined period (e.g., one hour), the natural cooling of the smart plug 1 and the temperature rise of the smart plug 1 due to the power consumption of the electrical device become balanced, and the temperature correction value becomes approximately constant. Note that the relationship information showing the relationship between the elapsed time and the temperature correction value is a function that outputs a correction value in response to an input of an elapsed time, but is not limited to this and may be table information that associates a correction value with each of a plurality of elapsed times.

[0039] FIG. 5 is a diagram showing an example of a relationship information specification table. In FIG. 5, T_corr indicates a temperature correction value, and t indicates an elapsed time. ci (t) (where i is an integer equal to or greater than 0) indicates a correction value calculation function, which is a function for calculating a temperature correction value, which is relationship information. In Fig. 5, it can be seen that a correction value calculation function is associated with state 1 of smart plug 1 and each of multiple ranges of the amount of supplied power W.

[0040] 5, the relationship information identifying table includes the state of the smart plug 1, but is not limited to this. Because it is possible to identify whether the state of the smart plug 1 is in a no-load state or a loaded state based on the calculation result of the amount of power supply W, the relationship information identifying table does not necessarily have to include the state of the smart plug 1.

[0041] The calculation unit 133 refers to the relationship information identification table stored in the storage unit 12, and identifies a correction value calculation function as relationship information associated with a range corresponding to the amount of supplied power, which is the amount of power supplied per unit time identified by the identification unit 131. For example, when the state of the smart plug 1 is a loaded state, the calculation unit 133 refers to the storage unit 12, and identifies a correction value calculation function that is associated with the loaded state and is associated with the range corresponding to the amount of supplied power identified by the identification unit 131.

[0042] Here, the identifying unit 131 identifies the amount of power supplied per unit time based on the amount of power supplied during a predetermined period from a time that is the second time before the current time to the current time, which is indicated by the supply history information. Therefore, the amount of power supplied per unit time identified by the identifying unit 131 after power supply to the electric device is stopped gradually decreases. This allows the calculating unit 133 to identify a correction value calculation function that corresponds to the cooling state of the smart plug 1 after power supply to the electric device is stopped.

[0043] In addition, when the state of the smart plug 1 is an unloaded state, the calculation unit 133 refers to the memory unit 12 and identifies a correction value calculation function that is associated with the unloaded state and indicates the relationship between the elapsed time in the unloaded state (elapsed time under unloaded state) and the temperature correction value.

[0044] Then, calculation unit 133 calculates a correction value based on the identified correction value calculation function and the elapsed time identified by identification unit 131. For example, when the smart plug 1 is in a loaded state, calculation unit 133 calculates the temperature correction value by inputting the elapsed time under load to the identified correction value calculation function. For example, when the smart plug 1 is in an unloaded state, calculation unit 133 calculates the temperature correction value by inputting the elapsed time under unload to the identified correction value calculation function.

[0045] The transmitting unit 134 transmits information indicating the temperature of the place where the smart plug 1 is installed, based on the temperature indicated by the temperature information acquired by the acquiring unit 132 and the temperature correction value calculated by the calculating unit 133, to a server as an external device. For example, the transmitting unit 134 subtracts the temperature correction value calculated by the calculating unit 133 from the temperature indicated by the temperature information acquired by the acquiring unit 132 at a first time interval to calculate the temperature of the place where the smart plug 1 is installed. Then, the transmitting unit 134 transmits temperature information indicating the calculated temperature and the time when the temperature was calculated to the server. In this way, the server side can grasp the temperature of the residential environment where the smart plug 1 is installed.

[0046] In addition, the transmitting unit 134 transmits the temperature information and the time when the temperature was calculated to the server at a timing according to the calculation of the temperature, that is, at a first time interval, but this is not limited thereto. For example, the control unit 13 may function as a setting unit, and in response to receiving a time interval for transmitting the temperature information to the server, the time interval may be set, and the transmitting unit 134 may transmit the temperature information and the time when the temperature was calculated to the server at the time interval. In addition, the transmitting unit 134 may transmit the temperature information and the time when the temperature was calculated to the server at a second time interval longer than the first time interval. By transmitting the temperature information to the server at the second time interval longer than the first time interval, the information processing device 10 can reduce power consumption related to the data transmission process and reduce the amount of communication data transmitted to the server.

[0047] [Operation flow] Next, a description will be given of a process flow related to the information processing device 10. Fig. 6 is a flowchart showing an example of a process flow related to the information processing device 10. This flowchart is assumed to be executed at a first time interval.

[0048] First, the identifying unit 131 acquires measurement result information from the power meter 6 to identify the cumulative value of the amount of power supply at the current point in time (S1). Next, the identification unit 131 refers to the measurement history information stored in the memory unit 12 and having a measurement time newer than the second time before the current time, and identifies the latest accumulated value of the amount of supplied power and the oldest accumulated value of the amount of supplied power (S2).

[0049] Next, the determination unit 131 determines whether the state of the smart plug is in a loaded state or an unloaded state based on the latest accumulated value of the amount of power supplied, the oldest accumulated value of the amount of power supplied, and the measurement times associated with these accumulated values ​​(S3).

[0050] Next, the identifying unit 131 identifies the amount of supplied power per unit time based on the latest accumulated value of the amount of supplied power, the oldest accumulated value of the amount of supplied power, and the measurement times associated with these accumulated values ​​(S4).

[0051] Next, the identifying unit 131 identifies an elapsed time based on the measurement time associated with the latest accumulated value of the amount of supplied power and the measurement time associated with the oldest accumulated value of the amount of supplied power (S5).

[0052] Next, the calculation unit 133 refers to the relationship information identification table stored in the storage unit 12, and identifies a correction value calculation function associated with the range corresponding to the amount of power supply identified in S4 (S6). Next, the calculation unit 133 inputs the elapsed time identified in S5 into the correction value calculation function identified in S6, and calculates a temperature correction value (S7).

[0053] Next, the transmitting unit 134 subtracts the temperature correction value calculated by the calculating unit 133 from the temperature indicated by the temperature information acquired by the acquiring unit 132, and calculates the temperature of the location where the smart plug 1 is installed (S8). Then, the transmitting unit 134 transmits temperature information indicating the calculated temperature and the time when the temperature was calculated to the server (S9).

[0054] [Variation 1] In the above embodiment, the information processing device 10 is provided in the smart plug 1, but this is not limited thereto. For example, a server that collects various information measured by the smart plug 1 may function as the information processing device 10. In this case, the smart plug 1 transmits to the server measurement result information indicating the cumulative value of the amount of power supplied to the electrical device measured by the power meter 6 and temperature information indicating the temperature of the smart plug 1 measured by the temperature sensor 7. The server calculates a temperature correction value based on the cumulative value of the amount of power indicated by the received measurement result information. In this way, it is possible to reduce measurement errors in the temperature of the living environment of the user in which the smart plug 1 is installed, similar to the case where the information processing device 10 is provided in the smart plug 1.

[0055] [Variation 2] In the above embodiment, the identifying unit 131 acquires from the power meter 6 measurement result information indicating a cumulative value of the amount of power supplied to the electrical device connected to the socket 3 as measurement result information indicating the measurement result of the amount of power supplied to the electrical device connected to the socket 3, but this is not limited to the above. The identifying unit 131 may acquire from the power meter 6 measurement result information indicating the amount of power supplied per first time to the electrical device connected to the socket 3. Then, the identifying unit 131 may identify the amount of power supplied per unit time based on the measurement result information.

[0056] [Effects of the information processing device 10] As described above, the information processing device 10 according to the present embodiment identifies the amount of power supplied to one or more electrical devices connected to the socket 3 of the smart plug 1, acquires temperature information indicating the temperature of the smart plug 1, and calculates a correction value for correcting the temperature indicated by the acquired temperature information to the temperature of the location where the smart plug 1 is installed based on the identified amount of power. In this way, the information processing device 10 can reduce measurement error in the temperature of the user's living environment.

[0057] Furthermore, this invention will make it possible to contribute to Goal 9 of the United Nations' Sustainable Development Goals (SDGs), which is to "build resilient infrastructure, promote industry, innovation and infrastructure."
