Abstract
A receiving unit (292) receives the earthquake notification. When receiving the earthquake notification, the storage section (291) stores the reception of the earthquake notification. When receiving the earthquake notification, the 1 st stop unit (210) closes the electrical path (102) and stops the supply of power to the electrical product (130). When the operation button (204) is pressed, and reception of the earthquake notification is stored and the electric path is closed, the restart unit (220) restarts power supply to the electric product by opening the electric path. When the earthquake notification is received and the electric path is opened when the power is recovered after the power failure, a 2 nd stop unit (230) stops the power supply to the electric product by closing the electric path.
Description
Technical Field
The present invention relates to a technique for preventing an electric fire.
Background
Power outages will occur in the event of a large-scale earthquake. In addition, the electric product falls down in the power-on state. In a state where an electric appliance is in contact with a combustible material, a fire may occur when the electric appliance recovers from a power failure, and a secondary disaster may be expanded.
In the event of a large-scale earthquake, power operation such as turning off a power supply for electrical equipment or pulling down an indoor breaker is performed, but in practice, evacuation is the most priority in the event of a large-scale earthquake, and therefore, power operation is difficult.
In the technique disclosed in patent document 1, a receiving device, an earthquake sensor, and a shutter are mounted on an electricity meter, and after the receiving device receives an earthquake early warning, the shutter is turned to an "off" state based on the earthquake intensity detected by the earthquake sensor. This cuts off the supply of electric power to the room.
Further, patent document 1 describes that the shutter that is in the "off" state is in the "on" state by operating a recovery button attached to the electricity meter.
In the technique disclosed in patent document 2, in a smart meter system of an electric power company, a main terminal receives an earthquake early warning, extracts a smart meter of a region to be subjected to earthquake early warning, and issues a control command for a shutter of the extracted smart meter.
Patent document 2 describes the following. The controller is connected with the intelligent instrument and displays whether to continue or stop power supply on the controller. A user wishing to continue the supply of power operates the controller and the smart meter responds to the continued supply of power via the network of smart meters. The power company performs an operation of bringing the shutter of the smart meter into an "off" state via the smart meter network with respect to the smart meter that has not responded to the continued power supply. When the shutter is in the "off" state, the user operates the controller, and the smart meter requests the restart of the power supply via the smart meter network. The power company performs an operation of bringing the shutter of the smart meter into an on state via the smart meter network with respect to the smart meter that requests resumption of power supply. Thereby, the power supply is started again.
in the technique disclosed in patent document 3, an indoor receiver notifies an emergency earthquake rapid report to a smart meter via an hems (home Energy Management system), and the smart meter turns a shutter into an "off" state in accordance with the earthquake degree detected by an earthquake sensor.

Disclosure of Invention
Problems to be solved by the invention
In the technique disclosed in patent document 1, when a power failure occurs without detecting a shock of the order of "off" of the shutter and the electrical product falls down by a large aftershock thereafter, it is not possible to reliably prevent an energization fire after the power failure is recovered.
Further, patent document 1 does not describe any restriction on the operation of the resume button. That is, the recovery button is operated by mischief or malicious intent, and the shutter changes from the "off" state to the "on" state. For example, in an empty house or an empty room, the shutter is changed from the "off" state to the "on" state by mischief or malicious intent.
In the technique disclosed in patent document 2, it is necessary to display the earthquake warning message to the controller, wait for a response from a user operation, and operate the shutter during a period from when the earthquake warning message is received to when the earthquake arrives. Therefore, there is no guarantee that control of all the smart meters can be implemented until the earthquake arrives. In addition, when the smart meter network is damaged by a disaster and a user wishes to restart the power supply, there is no guarantee that the smart meter network will function normally. Therefore, the power supply may not be restarted.
Patent document 3 does not describe a means for restarting the power supply after the shutter is turned to the "off" state.
These prior art techniques show operations related to the reception of an emergency earthquake prompt, the detection of an earthquake by an earthquake sensor, the confirmation of the user's will of the supply of electric power and the operation of the shutter. However, the following matters have not been considered in the prior art.
In large-scale earthquakes, long-time power failure and intermittent power failure occur because a large aftershock persists even after the initial earthquake occurs. Therefore, it may not be possible to receive the earthquake early warning from 2 nd time. In addition, the seismic sensors may not be operational. As a result, there is a possibility that an electric fire may occur.
In the conventional technique, when the magnitude of the earthquake detected by the earthquake sensor is small and the user does not intend to continue the power supply, the shutter is turned to the "off" state.
However, in the first order, a television or the like is required to obtain information on an earthquake. In addition, in case of an earthquake occurring at night, it is safer to use illumination. In some cases, the power supply is stopped by controlling the switch of the smart meter, which does not necessarily bring about user safety.
There is a certain amount of time between the receipt of the first earthquake early warning and the arrival of the earthquake. Therefore, when the electric appliance is in use, the power supply of the electric appliance can be cut off. However, if the power supply is stopped by the control of the switch or if the power supply is stopped due to a power failure before the power supply to the electric appliance is turned off, the user is assumed to be evacuated to the outside without turning off the power supply to the electric appliance. As a result, when the power supply is restarted, there is a possibility that an energization fire may occur.
The purpose of the present invention is to prevent an electrified fire when power is restored after a power failure.
Means for solving the problems
The intelligent instrument of the invention is provided with:
A receiving unit that receives an earthquake notification;
A storage unit that stores reception of the earthquake notification when the earthquake notification is received;
A 1 st stop unit that stops power supply to the electrical product by closing the electrical path when the earthquake notification is received; and
And a 2 nd stop unit that stops the supply of electric power to the electric product by closing the electric path when the reception of the earthquake notification is stored and the electric path is opened when the electric power is restored after the power failure.
Effects of the invention
According to the present invention, when the earthquake notification is received at the time of power restoration after power failure, the supply of power to the electric appliance can be stopped. Therefore, even if the supply of electric power to the electric appliance is restarted before the power failure, the energization fire can be prevented when the electric power is restored.

Description of actions
The operation of the smart meter 200 corresponds to the power supply control method. Further, the procedure of the power supply control method is equivalent to that of the power supply control program.
the 1 st stop processing will be described with reference to fig. 3.
The 1 st stop processing is processing when the earthquake notification reaches the smart meter 200.
The earthquake notification is a notification notifying the occurrence of an earthquake. In particular, the seismic notification is an emergency earthquake prompt.
when receiving the earthquake early warning sent by the meteorological office, the electric power system 110 determines a notification object area according to the content of the earthquake early warning. Then, the power system 110 transmits the earthquake early warning to the smart meter 200 in the notification target area.
in step S111, the reception unit 292 receives the earthquake notification.
In step S112, the control unit 240 determines whether or not the notification reception is stored in the storage portion 291. The notification reception means reception of an earthquake notification.
Specifically, the control unit 240 determines whether or not the notification reception in the 1 st target period is stored in the storage unit 291. The 1 st object period is a period before the current notification is received, and has a predetermined period length. For example, the length of the 1 st subject period is 1 month.
If the notification reception is stored in the storage portion 291, the process proceeds to step S114.
If the notification reception is not stored in the storage portion 291, the process proceeds to step S113.
In step S113, the control unit 240 stores the notification reception in the storage unit 291.
Specifically, the control unit 240 stores the reception time of the earthquake notification in the storage unit 291. The reception time is represented by the date and time. The time of day is obtained from the clock 906.
In step S114, the 1 st stop 210 closes the electrical path 102.
Specifically, the 1 st stop portion 210 closes the electrical path 102 by controlling the shutter 202.
In step S114, the supply of electric power to the electric appliance 130 is stopped.
With reference to fig. 4, the restart process will be described.
The restart processing is processing when the operation is restarted.
The restart operation is an operation for restarting the supply of electric power to the electric appliance 130. Specifically, the restart operation is the pressing of the restart button 204.
When the user wants to restart the supply of power to the electric appliance 130, the user presses the restart button 204.
In step S121, when the resume button 204 is pressed, the control unit 240 detects the pressing of the resume button 204, that is, the resume operation.
In step S122, the start section 220 determines the state of the electrical path 102 again.
Specifically, the restart unit 220 obtains the state information of the electric path 102 from the shutter 202. Then, the resuming portion 220 determines whether the state of the electrical path 102 is the on state or the off state by referring to the state information of the electrical path 102 again. The state information of the electrical path 102 is information representing the state of the electrical path 102.
The open state is a state in which the electrical path 102 is open. When the electrical path 102 is in the open state, power is supplied to the electrical product 130.
The closed state is a state in which the electrical path 102 is closed. When the electrical path 102 is in the closed state, the supply of power to the electrical product 130 is stopped.
In the case where the electrical path 102 is in the open state, the restart process is ended.
In the case where the electrical path 102 is in the closed state, the process advances to step S123.
In step S123, the start section 220 opens the electrical path 102 again.
Specifically, the restart unit 220 opens the electrical path 102 by controlling the shutter 202.
In step S123, the power supply to the electric appliance 130 is started again.
The 2 nd stop processing will be described with reference to fig. 5.
The 2 nd stop processing is processing performed when power is restored after power failure.
In step S131, the detector 203 detects power restoration after power failure.
In step S132, stop 2 unit 230 determines whether or not the notification reception is stored in storage 291.
Specifically, the 2 nd stopping unit 230 determines whether or not the notification reception in the 2 nd target period is stored in the storage 291. The 2 nd target period is a period immediately before the power recovery detection, and has a predetermined period length. For example, the length of the 2 nd subject period is 1 month.
If the notification reception is stored in the storage portion 291, the process proceeds to step S133.
when the notification reception is not stored in the storage portion 291, the 2 nd stop processing is ended.
In step S133, the 2 nd stop opening part 230 determines the state of the electrical path 102.
Specifically, the 2 nd opening stopper 230 obtains the state information of the electric path 102 from the shutter 202. Then, the 2 nd stop opening part 230 determines whether the state of the electrical path 102 is the open state or the closed state by referring to the state information of the electrical path 102.
In the case where the electrical path 102 is in the on state, the process advances to step S134.
In the case where the electrical path 102 is in the closed state, the 2 nd stop process ends.
In step S134, the 2 nd stop 230 closes the electrical path 102.
Specifically, the 2 nd stopping portion 230 closes the electrical path 102 by controlling the shutter 202.
In step S134, the supply of electric power to the electric appliance 130 is stopped again.
Effects of embodiment 1
the smart meter 200 can prevent an electric fire in the event of a major earthquake by stopping the supply of electric power to the home of the user in the 1 st stop process when a major earthquake such as an earthquake early warning is initiated.
when the power failure is recovered from a power failure that occurs for a long period of time or intermittently due to a follow-up aftershock after a major earthquake or the like, the smart meter 200 can prevent an electric fire when the power failure is recovered by stopping the supply of electric power to the home of the user in the 2 nd stop process.
The smart meter 200 restarts the supply of power to the home of the user in the restart process when the restart button 204 is pressed, and thus can restart the supply of power to the home of the user even in a situation where communication with the power system 110 is not possible.
Other structure
The smart meter 200 may communicate in a manner different from any of the specific low power wireless communication, power line carrier communication, and cellular phone communication.
The smart meter 200 may also receive an earthquake notification from a sender other than the power system 110. For example, the smart meter (200G or 200H) may also receive the earthquake early warning from the server of the operator providing the earthquake early warning through mobile phone communication.
The hubs (121, 122) may also receive an emergency earthquake prediction from a sender outside of the power system 110. When the earthquake early warning is received, the hubs (121, 122) transmit an earthquake notification to the subordinate smart meters (200A to 200F).
The hubs (121, 122) transmit earthquake notification to the subordinate smart meters (200A to 200F), thereby reducing the load on the power system 110. That is, in the power system 110, the delivery object extraction time and the notification delivery time can be shortened. The delivery target extraction time is a time for extracting the smart meter 200 to be a delivery target of the earthquake notification. The notification issuance time is a time for issuing the earthquake notification to the extracted smart meter 200.
The smart meter (200G, 200H) may be provided with a notification unit having a mail function. The notification section transmits the supply stop notification and the supply restart notification to the registration address using the communication device 904. The supply stop notification is a notification for notifying that the electric product 130 is stopped from supplying electric power, and the supply restart notification is a notification for notifying that the electric product 130 is restarted from supplying electric power. The registered address is a mail address registered in the storage portion 291 in advance. For example, the user requests one or more mail addresses from the electric power company, and the requested mail addresses are transmitted from the electric power system 110 to the smart meter 200 via the network 101 and registered in the storage 291.
Embodiment mode 2
a method for stopping or continuing the supply of electric power to the electric appliance 130 in response to a request from a user will be described with reference to fig. 6, which is different from embodiment 1.
Description of the structure
The configuration of the smart meter system 100 is the same as that in embodiment 1 (see fig. 1).
The configuration of the smart meter 200 is the same as that in embodiment 1 (see fig. 2).
however, the storage 291 stores control information in advance.
The control information is information indicating that the supply is stopped or continued.
the stop of the supply means stopping the supply of the electric power to the electric appliance 130.
The continuous supply means that the supply of electric power to the electric appliance 130 is continued.
For example, when the user signs up with the electric power company, when the conventional electric meter is replaced with the smart meter 200, or when the user requests the electric power company, the control information is stored in the storage portion 291.
For example, the control information is set in the storage portion 291 through the power system 110. Specifically, the power system 110 transmits a setting request to the smart meter 200. The setting request is data for requesting setting of control information, and includes control information. In the smart meter 200, the receiving unit 292 receives the setting request, and the control unit 240 sets the control information included in the setting request to the storage unit 291.
Description of actions
The 1 st stop processing will be described with reference to fig. 6.
Steps S211 to S213 are the same as steps S111 to S113 in embodiment 1 (see fig. 3).
In step S214, the 1 st stop unit 210 determines whether the control information indicates stopping or continuing the supply.
If the control information indicates that the supply is stopped, the process proceeds to step S215.
When the control information indicates that the supply is continued, the power supply to the electrical appliance 130 is not stopped, and the 1 st stop process is ended.
In step S215, the 1 st stop 210 closes the electrical path 102.
Specifically, the 1 st stop portion 210 closes the electrical path 102 by controlling the shutter 202.
According to step S215, the supply of electric power to the electric appliance 130 is stopped.
Effects of embodiment 2
At the stage of receiving the earthquake early warning, there is a certain time until the earthquake-induced shock occurs, and thus, the user can cut off the power of the electric appliance 130. Further, when an earthquake occurs first, there is a demand for collecting information from a television or the like as much as possible. In addition, when an earthquake occurs at night, there is a demand for using illumination in order to cope with safety. In this way, even when an earthquake occurs, it may be preferable not to stop the supply of electric power to the electric appliance 130.
the smart meter 200 selects to stop or continue the supply of power to the electric product 130 according to the control information. That is, the smart meter 200 can select whether to preferentially prevent an electrified fire or to preferentially maintain power supply when an earthquake occurs.
Embodiment 3
A description will be given of a method for stopping or continuing the supply of electric power to the electric appliance 130 in accordance with the date and time when the earthquake notification is received or the amount of electric power used when the earthquake notification is received, mainly with reference to fig. 7, which is different from embodiment 1.
Description of the structure
The configuration of the smart meter system 100 is the same as that in embodiment 1 (see fig. 1).
The configuration of the smart meter 200 is the same as that in embodiment 1 (see fig. 2).
However, the storage 291 stores the stop condition in advance.
The stop condition is a condition for stopping the supply of electric power to the electric appliance 130.
For example, the stop condition is stored in the storage portion 291 when the user signs up with the electric power company, when the conventional electric meter is replaced with the smart meter 200, when the user requests the electric power company, or the like.
For example, the stop condition is set in the storage portion 291 by the power system 110. Specifically, the power system 110 transmits a setting request to the smart meter 200. The setting request is data for requesting setting of the stop condition, and includes the stop condition. In the smart meter 200, the receiving unit 292 receives the setting request, and the control unit 240 sets the stop condition included in the setting request to the storage unit 291.
Description of actions
The 1 st stop processing will be described with reference to fig. 7.
Steps S311 to S313 are the same as steps S111 to S113 in embodiment 1 (see fig. 3).
In step S314, the 1 st stop unit 210 determines whether or not the stop condition is satisfied.
In the case where the stop condition is satisfied, the process proceeds to step S315.
If the stop condition is not satisfied, the power supply to the electrical appliance 130 is not stopped, and the 1 st stop process is ended.
In step S315, the 1 st stop 210 closes the electrical path 102.
specifically, the 1 st stop portion 210 closes the electrical path 102 by controlling the shutter 202.
According to step S315, the supply of power to the electric appliance 130 is stopped.
An example of step S314 (see fig. 7) is explained below.
Description of the embodiments
in step S314, the 1 st stop unit 210 determines whether or not the stop condition is satisfied based on the reception timing of the earthquake notification. That is, the 1 st stop unit 210 determines whether or not to stop the power supply based on the reception timing of the earthquake notification. If it is determined that the power supply is stopped, the 1 st stopping portion 210 closes the electrical path 102 (S315).
The stop condition is a season in which it is better to stop the supply of electric power to the electric appliance 130. For example, electric fires are the cause of energized fires. Therefore, the season in which the electric furnace is used (for example, 12 months to 3 months) becomes the stop condition.
Specifically, the 1 st stop unit 210 determines the season to which the reception time belongs, that is, the reception season. Then, the 1 st stop portion 210 determines whether the reception season satisfies the stop condition. That is, the 1 st stop unit 210 determines whether or not to stop the supply of electric power according to the reception season.
Description of the embodiments
In step S314, the 1 st stop unit 210 determines whether or not the stop condition is satisfied based on the reception timing of the earthquake notification. That is, the 1 st stop unit 210 determines whether or not to stop the power supply based on the reception timing of the earthquake notification. If it is determined that the power supply is stopped, the 1 st stopping portion 210 closes the electrical path 102 (S315).
The stop condition is a time period in which it is better to stop the supply of electric power to the electric appliance 130. For example, no lighting is needed at night, but lighting is needed during the day. Therefore, the daytime period (for example, 6 o 'clock to 18 o' clock) becomes the stop condition.
Specifically, 1 st stop unit 210 determines a reception time period, which is a time period to which the reception time belongs. Then, the 1 st stop section 210 determines whether or not the reception period satisfies the stop condition. That is, the 1 st stop unit 210 determines whether or not to stop the supply of electric power based on the reception time period.
description of embodiments of the invention
In step S314, the 1 st stop unit 210 determines whether or not the stop condition is satisfied based on the reception timing of the earthquake notification. That is, the 1 st stop unit 210 determines whether or not to stop the power supply based on the reception timing of the earthquake notification. If it is determined that the power supply is stopped, the 1 st stopping portion 210 closes the electrical path 102 (S315).
The stop condition is a condition including the season explained in embodiment 1 and the time period explained in embodiment 2. For example, the stop condition is a condition such as winter or daytime.
Description of the embodiments
In step S314, the 1 st stop unit 210 determines whether or not the stop condition is satisfied, based on the amount of power usage when the earthquake notification is received. That is, the 1 st stopping unit 210 determines whether or not to stop the power supply based on the amount of power used when the earthquake notification is received. If it is determined that the power supply is stopped, the 1 st stopping portion 210 closes the electrical path 102 (S315).
The stop condition is a power usage amount that is more preferable for stopping the supply of power to the electric appliance 130. For example, when a power failure occurs while a large number of electric appliances 130 are in use, there is a high possibility that an energization fire may occur when power is restored. Therefore, the threshold value of the amount of power usage becomes the stop condition.
Specifically, the 1 st stop unit 210 receives the power usage amount at the time of receiving the notification, and determines whether or not the power usage amount at the time of receiving the notification exceeds the power threshold. The power threshold is a threshold of the power usage amount.
Specifically, 1 st stop unit 210 obtains the amount of power usage when the notification is received as follows.
The measurement device 201 regularly measures the amount of power usage, and the control unit 240 stores the amount of power usage and the measurement time in the storage unit 291 each time the amount of power usage is measured.
When the power usage amount at the time of receiving the notification is obtained, the 1 st stop unit 210 obtains the current power usage amount from the measurement device 201, obtains the previous power usage amount from the storage unit 291, and calculates the difference between the current power usage amount and the previous power usage amount. The calculated difference is referred to as a power difference.
Then, the 1 st stopping unit 210 obtains the current time from the clock 906, obtains the last measurement time from the storage unit 291, and calculates the time from the last measurement time to the current time. The calculated time is referred to as elapsed time.
then, the 1 st stop unit 210 calculates the amount of power usage per unit time by dividing the difference in power by the elapsed time. The power usage amount per unit time is the power usage amount at the time of receiving the notification.
description of the embodiments of the invention 5
In step S314, the 1 st stop unit 210 determines whether or not the stop condition is satisfied, based on the reception time of the earthquake notification and the power usage amount at the time of receiving the earthquake notification. That is, the 1 st stopping unit 210 determines whether or not to stop the power supply based on the reception time of the earthquake notification and the power usage amount when the earthquake notification is received. If it is determined that the power supply is stopped, the 1 st stopping portion 210 closes the electrical path 102 (S315).
The stop condition is a condition including at least one of the season described in embodiment 1 and the time period described in embodiment 2 and the power threshold described in embodiment 4. For example, the stop condition is a condition that the power usage is higher than the power threshold value in winter or daytime.
Effects of embodiment 3
The smart meter 200 selects to stop or continue the supply of power to the electric product 130 according to the reception timing or the power usage amount. That is, the smart meter 200 can select whether to preferentially prevent an electrified fire or to preferentially maintain power supply when an earthquake occurs.
Other structure
Instead of the stop condition, a continue condition may be used.
The continuation condition is a condition for continuing the supply of electric power to the electric appliance 130.
The 1 st stop 210 closes the electrical path 102 if the continuation condition is not satisfied.
Embodiment 4
A method for preventing resumption of power supply due to mischief or malicious intent will be described with reference to fig. 8, which is different from embodiment 1.

The configuration of the smart meter 200 is the same as that in embodiment 1 (see fig. 2).
Description of actions
The restart process will be described with reference to fig. 8.
In step S421, when the resume button 204 is pressed, the control unit 240 detects the pressing of the resume button 204, that is, the resume operation.
in step S422, the restart unit 220 determines whether or not the notification reception is stored in the storage unit 291.
specifically, the restart unit 220 determines whether or not the notification reception in the 3 rd object period is stored in the storage unit 291. The 3 rd target period is a period immediately before the restart operation detection, and has a predetermined period length. For example, the length of the 3 rd subject period is 1 month.
If the notification reception is stored in the storage portion 291, the process proceeds to step S423.
When the notification reception is not stored in the storage portion 291, the power supply to the electrical appliance 130 is not started again, and the process is restarted and ended.
In step S423, the start part 220 determines the state of the electrical path 102 again. The determination method is the same as step S122 (see fig. 4) in embodiment 1.
In the case where the electrical path 102 is in the open state, the restart process is ended.
In the case where the electrical path 102 is in the closed state, the process advances to step S424.
in step S424, the start portion 220 opens the electrical path 102 again.
Specifically, the restart unit 220 opens the electrical path 102 by controlling the shutter 202.
In step S424, the supply of electric power to the electric appliance 130 is started again.
Effects of embodiment 4
In a normal state other than the earthquake, when the operation is restarted by mischief or malicious intent, the supply of electric power to the electric appliance 130 can be prevented from being restarted.
