Problems solved by technology

[0003] As an action in the event of a large-scale earthquake, power operations such as turning off the power of electrical equipment or pulling down the indoor circuit breaker are called, but in fact, evacuation is the top priority in the event of a large-scale earthquake, so it is difficult to perform power operations

Embodiment approach 1

[0044] according to Figure 1 to Figure 5 , to explain the method for preventing electric fire in the event of an earthquake.

[0045] ***Description of structure***

[0046] according to figure 1 , the structure of the smart meter system 100 will be described.

[0047] The smart meter system 100 is a system for supplying electric power from a power company to each user's house.

[0048] Power companies are suppliers of electricity.

[0049] The user's home is the residence of the user, and is a supply object of electric power.

[0050] The smart meter system 100 includes a power system 110 , a hub 121 , a hub 122 , a base station 123 , and a plurality of smart meters ( 200A to 200H).

[0051] The plurality of smart meters ( 200A to 200H) are called smart meters 200 , respectively.

[0052] The smart meter 200 is a high-performance electric meter. For example, the smart meter 200 has a communication function.

[0053] The electric power system 110 is a system of an ele...

Embodiment approach 2

[0148] The way of stopping or continuing the power supply to the electrical appliance 130 according to the user's request is mainly based on Figure 6 , and points different from Embodiment 1 will be described.

[0149] ***Description of structure***

[0150] The structure of the smart meter system 100 is the same as that in Embodiment 1 (refer to figure 1 )same.

[0151] The structure of the smart meter 200 is the same as that in Embodiment 1 (refer to figure 2 )same.

[0152] However, control information is stored in advance in the storage unit 291 .

[0153] The control information is information indicating whether to stop supply or to continue supply.

[0154] Stopping the supply means stopping the power supply to the electric appliance 130 .

[0155] Continuing the supply means continuing to supply electric power to the electric product 130 .

[0156] For example, the control information is stored in the storage unit 291 when the user signs a contract with the ele...

Embodiment approach 3

[0171] As for the method of stopping or continuing the power supply to the electric appliance 130 according to the date and time when the earthquake notice was received or the power consumption when the earthquake notice was received, it is mainly based on Figure 7, and points different from Embodiment 1 will be described.

[0172] ***Description of structure***

[0173] The structure of the smart meter system 100 is the same as that in Embodiment 1 (refer to figure 1 )same.

[0174] The structure of the smart meter 200 is the same as that in Embodiment 1 (refer to figure 2 )same.

[0175] However, the stop conditions are stored in advance in the storage unit 291 .

[0176] The stop condition is a condition for stopping the supply of electric power to the electric appliance 130 .

[0177] For example, the stop condition is stored in the storage unit 291 when the user signs a contract with the electric power company, when the conventional electric meter is replaced with ...

Abstract

The present invention provides a smart meter in which a receiving unit (292) receives earthquake notification. When the earthquake notification is received, a storage unit (291) stores the reception of the earthquake notification. When the earthquake notification is received, a first stop unit (210) closes an electrical path (102), thereby stopping power supply to electric appliances (130). When an operation button (204) is pressed, if the reception of the earthquake notification is stored and the electrical path is closed, a resuming unit (220) opens the electrical path, thereby resuming power supply to the electric appliances. When power is restored after a power failure, if the reception of the earthquake notification is stored and the electrical path is opened, a second stop unit (230)closes the electrical path, thereby stopping power supply to the electric appliances.

Description

technical field [0001] The present invention relates to techniques for preventing energized fires. Background technique [0002] Power outages will occur in the event of a large-scale earthquake. In addition, the electric appliance falls down while it is turned on. In the state where electrical products are in contact with combustibles, a fire may occur when recovering from a power outage, and secondary disasters may expand. [0003] As an action in the event of a large-scale earthquake, power operations such as turning off the power of electrical equipment or pulling down indoor circuit breakers are called, but in reality, evacuation is the top priority in the event of a large-scale earthquake, so it is difficult to perform power operations. [0004] In the technique disclosed in Patent Document 1, a receiving device, an earthquake sensor, and a switch are mounted on an electric meter, and after the receiving device receives an emergency earthquake early warning, the swit...
