Note that each of the embodiments described below shows a preferred specific example of the present disclosure. Therefore, the numerical values, materials, components, arrangements of components, connection forms, etc. shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Thus, among the following embodiments, components not described in the independent claims indicating the uppermost concept of the present disclosure are described as optional components. Note that each of the drawings referred to in the following embodiments is a schematic diagram and is not necessarily drawn precisely. That is, the ratios of the sizes and thicknesses of the respective components in the drawings do not necessarily reflect the actual dimensional ratios.

[0010] [First Embodiment] First, the overall configuration of the distribution board 1 according to the first embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a block diagram of the distribution board 1 according to the first embodiment. FIG. 2 is a front view of the distribution board in the distribution board 1 according to the first embodiment. As shown in FIGS. 1 and 2, the distribution board 1 according to the first embodiment is mainly provided in a house and includes a circuit 4, a circuit breaker 100 incorporated in the distribution board 1, a power restoration information output unit 150, a measurement unit 200, a power supply unit 300, and a display unit 400. The circuit breaker 100 has a main breaker 110 and a plurality of branch breakers 120. The circuit 4 includes a first circuit 4a and a second circuit 4b. The first circuit 4a is a circuit on the power system 2 side (primary side of the main breaker 110) with respect to the main breaker 110. The second circuit 4b is a circuit on the load 3 side (secondary side of the main breaker 110) with respect to the main breaker 110. Hereinafter, each component provided in the distribution board 1 will be described in detail.

[0011] (1) Circuit Breaker As shown in FIGS. 1 and 2, the distribution board 1 includes a main breaker 110 and two or more branch breakers 120. The main breaker 110 is connected to the power system 2 on the primary side and has a function of shutting off the current in the circuit (entering the trip state) when overcurrent or leakage is detected. Note that the trip state is a state in which the contact between the first circuit 4a and the second circuit 4b is opened. The main breaker 110 enters the trip state when overcurrent or leakage occurs in the second circuit 4b. Also, the main breaker 110 enters the trip state based on the earthquake determination of the power restoration information output unit 150 when an earthquake occurs. When the main breaker 110 enters the trip state, the power supply to the load 3 is stopped. The branch breaker 120 is branched into two or more and connected to a plurality of loads 3. Here, the load 3 is a household electrical appliance that operates with the power from the power system 2. The load 3 is, for example, a refrigerator or a washing machine.

[0012] (Power Restoration Information Output Unit) FIG. 3 is a block diagram of a power restoration information output unit 150 in the distribution board 1 according to the first embodiment. As shown in FIG. 3, the power restoration information output unit 150 includes an acquisition unit 151, a processing unit 152, a storage unit 153, and an output unit 154, and outputs power restoration information including a power restoration method corresponding to cause information based on power outage information including cause information regarding the cause of the power outage. Further, when it is determined based on the measurement result of the measurement unit 200 that an overcurrent or the like has occurred (an earthquake has occurred), the power restoration information output unit 150 opens the contact between the first circuit 4a and the second circuit 4b through an opening / closing mechanism (not shown) that opens and closes the contact and a drive circuit (not shown) that drives the opening / closing mechanism, and shifts the main breaker 110 to the trip state. Hereinafter, each configuration of the power restoration information output unit 150 will be described in detail.

[0013] (Acquisition Unit) The acquisition unit 151 outputs power outage information including cause information regarding the cause of the power outage. The cause information includes information for at least indicating whether the power outage is a system power outage caused by the power grid 2 or an in-house power outage caused by the breaker 100 being in the trip state. When a power outage occurs, the acquisition unit 151 determines whether the power outage is a system power outage or an in-house power outage based on the measurement result of the measurement unit 200, and outputs first cause information that is a determination result indicating a system power outage or an in-house power outage. Further, when the acquisition unit 151 outputs first cause information indicating an in-house power outage, it determines whether the cause of the in-house power outage is an overcurrent, a leakage, or an earthquake based on the measurement result of the measurement unit 200, and outputs second cause information indicating the determination result (any one of an overcurrent, a leakage, and an earthquake).

[0014] When it is determined based on the measurement result of the measurement unit 200 that an overcurrent or the like has occurred, the acquisition unit 151 opens the contact between the first circuit 4a and the second circuit 4b through an opening / closing mechanism (not shown) that opens and closes the contact and a drive circuit (not shown) that drives the opening / closing mechanism, and shifts the main breaker 110 to the trip state.

[0015] (Processing Unit) As shown in FIG. 3, the processing unit 152 outputs restoration information including a restoration method corresponding to the cause information based on the power outage information acquired by the acquisition unit 151. Specifically, when the processing unit 152 acquires the first cause information indicating a system power outage, it outputs the first restoration information corresponding to the first cause information stored in the storage unit 153. Further, when the processing unit 152 acquires the second cause information indicating an in-house power outage, it outputs the second restoration information corresponding to the second cause information stored in the storage unit 153.

[0016] (Storage unit) The storage unit 153 stores various information (first cause information, second cause information, and their restoration information) acquired by the acquisition unit 151 as a database. Note that the storage unit 153 may be stored in a configuration other than the main breaker 110, or may be stored in a storage unit provided outside the distribution board 1.

[0017] (Output unit) The output unit 154 outputs power outage information, cause information (first cause information, second cause information), or restoration information including a restoration method from the processing unit 152. The information output by the output unit 154 is displayed by the display unit 400.

[0018] (2) Measurement unit The measurement unit 200 has at least a voltmeter (not shown) connected to the first circuit 4a, measures at least the voltage of the first circuit 4a which is the primary-side circuit of the main breaker 110, and acquires the voltage value which is the measurement result. Further, the measurement unit 200 measures at least the current of the second circuit 4b which is the secondary-side circuit of the main breaker 110 with an ammeter, and acquires the current value which is the measurement result. The measurement unit 200 measures its own acceleration with an accelerometer, and acquires the acceleration value which is the measurement result.

[0019] The measurement unit 200 delivers the three measurement results (voltage value, current value, and acceleration value) to the acquisition unit 151 of the restoration information output unit 150.

[0020] (3) Power supply unit When there is a power outage in the power supply unit 300, it supplies power to at least the power restoration information output unit 150, the display unit 400, and the measurement unit 200. The power supply unit 300 is usually a battery. The battery may be, for example, disposable but rechargeable. The power supply unit 300 is separate from the main breaker 110 and is provided in the distribution board 1. Note that the power supply unit 300 may be built into each of the power restoration information output unit 150, the display unit 400, and the measurement unit 200.

[0021] (4) Display unit The display unit 400 is provided in the distribution board 1 and can display power restoration information corresponding to the power outage information output by the output unit 154. The power restoration information is information including a power restoration method corresponding to the cause information. For example, it is a predetermined numerical value associated with the acquired power restoration information, a two-dimensional code including the acquired power restoration information, or a message describing the power restoration method. The display unit 400 is a display medium that projects characters, images, etc. According to this, since the power restoration information corresponding to the power outage information is displayed on the display unit 400 provided in the distribution board 1, if the user moves to the installation location of the distribution board 1, the user can surely acquire information (power restoration information) regarding the power outage. Also, the display unit 400 may be configured to emit light during a power outage. Thereby, the user can accurately grasp the display content during a power outage.

[0022] FIG. 4 is a front view of the display unit 400 when showing a predetermined number in the distribution board 1 according to the first embodiment. As shown in FIG. 4, the processing unit 152 outputs, for example, a predetermined numerical value associated with the power restoration information acquired from the acquisition unit 151, and the display unit 400 displays the predetermined numerical value. The user can acquire the power restoration method by referring to the correspondence diagram between the predetermined numerical value and the power restoration method. Also, a large amount of information can be transmitted with a small display amount of only numbers. The display unit 400 is a device capable of displaying a predetermined numerical value, for example, a 7-segment display.

[0023] FIG. 5 is a front view of the display unit 400 when showing the two-dimensional code in the distribution board 1 according to the first embodiment. As shown in FIG. 5, the display unit 400 displays a two-dimensional code including a message and the acquired power restoration information. The user can acquire the power restoration method by scanning the two-dimensional code. The display unit 400 is a device capable of displaying a two-dimensional code, for example, an electronic paper. By using the electronic paper, it leads to a reduction in power consumption.

[0024] Next, the operation of the distribution board 1 configured by the above elements during a power outage will be described in detail.

[0025] (Output of power outage information in the acquisition unit) When the voltage value of the first circuit 4a is equal to or less than the first threshold value (for example, voltage value = 0), or when the current value of the second circuit 4b is equal to or less than the second threshold value (for example, current value = 0), the acquisition unit 151 determines that a power outage has occurred.

[0026] (Output of first cause information in the acquisition unit) When it is determined that a power outage has occurred, the acquisition unit 151 further determines whether the power outage is a system power outage or an in-house power outage. Specifically, when the voltage value is equal to or less than the first threshold value (for example, voltage value = 0), the acquisition unit 151 determines that a system power outage has occurred. On the other hand, when the voltage value is greater than the first threshold value (for example, voltage value > 0) and the current value is equal to or less than the second threshold value (for example, current value = 0), the acquisition unit 151 determines that an in-house power outage has occurred. Then, based on the above determination result, the acquisition unit 151 outputs first cause information indicating a system power outage or an in-house power outage.

[0027] (Output of second cause information in the acquisition unit) When it is determined that a power outage has occurred in the house, the acquisition unit 151 further determines whether the cause of the power outage in the house is an overcurrent, a leakage, or an earthquake based on the current value, voltage value, and acceleration value included in the measurement result. Specifically, for example, when the current value exceeds the third threshold value, it is determined as an overcurrent. The current value includes two current values, the incoming and outgoing currents in the second circuit 4b. When the difference between the two current values exceeds the fourth threshold value, it is determined as a leakage. Furthermore, when the acceleration value in the measurement unit 200 exceeds the fifth threshold value, it is determined as an earthquake.

[0028] (Display of restoration power supply information (predetermined value)) FIG. 6 is a correspondence diagram between predetermined values and various information in the distribution board according to the first embodiment. When it is determined that a power outage has occurred in the house, the processing unit 152 outputs a restoration power supply method from the second cause information and displays the restoration power supply information on the display unit 400. Specifically, as follows, the restoration power supply information is displayed on the display unit 400. As shown in FIG. 6, in the correspondence diagram, the display number is associated with the second cause information and the restoration power supply method. The processing unit 152 extracts a predetermined value associated with the restoration power supply information from the database stored in the storage unit 153 and displays the predetermined value on the display unit 400. Or, the processing unit 152 extracts a predetermined value associated with the second cause information from the database stored in the storage unit 153 and displays the predetermined value on the display unit 400. For example, as shown in FIG. 4, when the second cause information is determined to be an overcurrent, the processing unit 152 outputs "02", which is a predetermined value, and displays "02" on the display unit 400.

[0029] When it is determined that a system power outage has occurred, the processing unit 152 outputs a predetermined value associated with the restoration power supply information obtained from the database stored in the storage unit 153 or a predetermined value associated with the cause information and displays it on the display unit 400.

[0030] (Display of restoration power supply information (2D code, etc.)) When it is determined that a power outage has occurred in the house, the processing unit 152 outputs a power restoration method from the first cause information and displays the power restoration information on the display unit 400. Specifically, the display unit 400 outputs a two-dimensional code associated with Internet information that can refer to the power restoration information or instruction manual information that can refer to the power restoration information from the database stored in the storage unit 153, and displays it on the display unit 400. As shown in FIG. 5, the display unit 400 displays a two-dimensional code associated with a site where the power restoration information can be referred to. Also, a message indicating that a power outage has occurred, such as "Power outage occurred", or a message regarding the power restoration method may be displayed.

[0034] Also, in the distribution board 1, the cause information includes information for at least indicating whether the power outage is a system power outage caused by the power outage in the power system 2 or a power outage in the house caused by the circuit breaker being in a tripped state.

[0035] According to this, since it is possible to grasp whether the power outage is a system power outage or a power outage in the house, it is possible to provide an appropriate power restoration method according to the power outage situation.

[0036] Also, in the distribution board 1, the power restoration information output unit 150 has a processing unit 152. The processing unit 152 outputs a predetermined numerical value associated with the acquired power restoration information. The display unit 400 displays the predetermined numerical value.
