FIG. 2 is a diagram illustrating an example of daily pattern data of a resident's weekday in a house where the automatic power shut-off device according to the present embodiment is installed. FIG. 3 is a diagram illustrating an example of life pattern data for a resident's holiday in a house where the automatic power shut-off device according to the present embodiment is installed. 2 and 3, the horizontal axis indicates the flow of time for one day (from 0:00 to 24:00), and the vertical axis indicates the change in power consumption consumed in the house. Hereinafter, the configuration of the automatic power shut-off device will be described with reference to FIGS.

  The automatic power shut-off device 1 is, for example, a home server installed in a house, and controls the power supply of the lighting device 3 and the distribution board 4 installed in the house, triggered by acquisition of information related to the occurrence of an earthquake. Device. The information on the occurrence of the earthquake is, for example, detailed information of the earthquake to be notified immediately after the occurrence of the earthquake (information on the epicenter, the seismic intensity of the area including the house, the influence of the tsunami, etc.). Information about the occurrence of an earthquake is acquired in real time from a server of an information agency such as the Japan Meteorological Agency through the computer network 2. When acquiring information related to the occurrence of an earthquake, the automatic power shut-off device 1 determines the presence / absence of home, the magnitude of the earthquake, and the time of occurrence of the earthquake in order to control the power supply of the lighting device 3 and the distribution board 4. Then, the automatic power shut-off device 1 determines that a resident is in the house, and if the value indicating the magnitude of the earthquake in the area including the house is greater than a predetermined value (for example, seismic intensity 4). If it is determined that the time of occurrence of the earthquake is a time in a predetermined time zone (for example, from 18:00 on the day to 6 o'clock on the next day), the lighting device 3 can be turned on for a certain period of time. After the time elapses, control is performed to automatically shut off the power supply of the distribution board 4.

  The automatic power shut-off device 1 includes a storage unit 1A, a control unit 1B, a first determination unit 1C, a second determination unit 1D, and a third determination unit 1E. The automatic power shut-off device 1 is a device including a microcomputer, and functions of the control unit 1B, the first determination unit 1C, the second determination unit 1D, and the third determination unit 1E are the control unit 1B. Is realized by executing a program stored in the storage unit 1D.

  In the storage unit 1A, program data for realizing each function of the automatic power shut-off device 1, and life pattern data indicating the lifestyle patterns of the resident of the house where the automatic power shut-off device 1 is installed, each weekday and holiday A, B, reference seismic intensity data indicating a predetermined seismic intensity (for example, seismic intensity 4), and time period data indicating a time period (for example, 18:00 on the current day to 6 o'clock on the next day) predetermined as night Stored in advance. The automatic power shut-off device 1 is communicably connected to the smart meter 5 via a communication line, and acquires power consumption data measured by the smart meter 5. The automatic power shut-off device 1 can acquire power consumption data from the smart meter 5 by transmitting a signal requesting the smart meter 5 to acquire power consumption data. The automatic power shut-off device 1 can also acquire power consumption data every time a fixed time (for example, 1 hour) elapses with reference to the current time measured by the time measuring unit 6. The life pattern data A and B is data generated based on past power consumption data acquired from the smart meter 5. The life pattern data A is obtained, for example, by accumulating power consumption data from 00:00 to 24:00 on weekdays (Monday to Friday) in the past six months by dividing every hour, and averaging the accumulated data. It is data. In addition, the life pattern data B is, for example, accumulated by dividing the hourly power consumption data from 0:00 to 24:00 on holidays (Saturday and Sunday) in the past six months, and averaging the accumulated data. Data obtained.

  The control unit 1B generates the above life pattern data A and B based on the power consumption data acquired from the smart meter 5, and stores the generated life pattern data A and B in the storage unit 1A. Note that the control unit 1B newly generates the life pattern data A and B, for example, every month so as to cope with the change in the life pattern of the resident of the house.

  The first determination unit 1C determines whether or not the resident is at home. Current power consumption data measured by the smart meter 5 is input to the first determination unit 1C, for example, every hour. The first determination unit 1C compares the current power consumption data measured by the smart meter 5 with either one of the life pattern data A and B read from the storage unit 1A, and compares the current power consumption data and the life pattern. When it is recognized that the difference from one of the data A and B is within a certain range, it is determined that the resident is at home. The first determination unit 1C refers to the current time measured by the clock unit 6 to determine whether the current day is a weekday or a holiday, and reads the life pattern data A from the storage unit 1A if the current day is a weekday. On the other hand, if the current day is a holiday, the life pattern data B is read from the storage unit 1A. In general, when the time of an earthquake occurs at midnight or dawn, the resident is likely to be asleep. Therefore, it is very important for the first determination unit 1C to determine whether or not the resident is at home in the state of sleeping. For example, the first determination unit 1C refers to the life pattern data A and B, specifies the time when the power consumption decreases and becomes substantially constant in the time zone predetermined as night, and determines the time. Set to the resident's bedtime (in the case of FIGS. 2 and 3, for example, the bedtime on weekdays is 0:00 and the bedtime on holidays is 3:00). And 1 C of 1st determination parts acquire the present electric power consumption data measured with the smart meter 5 just before bedtime, and when use of electric power is recognized, a resident is staying at home in the state which went to bed. It is determined that

  2nd determination part 1D determines whether the seismic intensity of the earthquake which generate | occur | produced in the area containing the said house is larger than the predetermined seismic intensity. Actual seismic intensity data included in the information related to the occurrence of the earthquake is input to the second determination unit 1D. The second determination unit 1D compares the actual seismic intensity data included in the information related to the occurrence of the earthquake with the reference seismic intensity data read from the storage unit 1A, and if the actual seismic intensity data is found to be larger than the reference seismic intensity data, the second determination unit 1D It is determined that the seismic intensity of the earthquake that occurred in the area including it is greater than the predetermined seismic intensity.

  The 3rd determination part 1E determines whether the occurrence time of the earthquake which generate | occur | produced in the area containing the said house is the time of the time slot | zone preset as night. The time determination data of the time measuring unit 6 when the automatic power shut-off device 1 acquires information related to the occurrence of the earthquake is input to the third determination unit 1E as the earthquake occurrence time data. The third determination unit 1E compares the earthquake occurrence time data with the time zone data read from the storage unit 1A, and determines whether or not the earthquake occurrence time is a time included in a time zone predetermined as night. To do.

  The control part 1B controls the power supply of the illuminating device 3 and the distribution board 4 according to the determination result of 1st determination part 1C, 2nd determination part 1D, and 3rd determination part 1E. The first determination unit 1C determines that the resident is in the house with the automatic power shut-off device 1 acquiring information related to the occurrence of the earthquake, and the seismic intensity of the earthquake occurring in the area including the house is determined. The second determination unit 1D determines that the seismic intensity is greater than a predetermined seismic intensity, and third determination is made that the occurrence time of the earthquake in the area including the house is a time included in a predetermined time zone as night. When the unit 1E determines, the control unit 1B enables the lighting device 3 to be lit for a certain time (for example, 5 minutes) for the purpose of quickly evacuating the residents of the house to a safe place indoors or outdoors. After the elapse of time, the power supply path of the distribution board 4 is shut off for the purpose of preventing the occurrence of fire due to electricity.

=== Operation of automatic power shut-off device ===
FIG. 4 is a flowchart showing the operation of the automatic power shut-off device according to this embodiment. Hereinafter, the operation of the automatic power shut-off device will be described with reference to FIGS.

  First, the automatic power shut-off device 1 determines whether or not information related to the occurrence of an earthquake has been acquired through a computer network 2 from a server of an information agency such as the Japan Meteorological Agency (step S1). When the information regarding the occurrence of the earthquake has not been acquired (step S1: NO), the automatic power shut-off device 1 repeatedly executes the determination operation of step S1 until the information regarding the occurrence of the earthquake is acquired.

  When the information regarding the occurrence of the earthquake is acquired (step S1: YES), the automatic power shut-off device 1 uses the seismic intensity of the earthquake in the area including the house as a function of the second determination unit 1D. Determine whether it is larger. Specifically, the automatic power shut-off device 1 compares the actual seismic intensity data included in the information related to the occurrence of the earthquake with the reference seismic intensity data read from the storage unit 1A (step S2).

  When the actual seismic intensity data is larger than the reference seismic intensity data (step S2: YES), the automatic power shut-off device 1 determines that the seismic intensity of the earthquake in the area including the house is greater than the predetermined seismic intensity, and the first determination As a function of the section 1C, it is determined whether or not the resident is at home. Specifically, the automatic power shut-off device 1 compares the current power consumption data measured by the smart meter 5 with the life pattern data A read from the storage unit 1A when the current day is a weekday, and the current day is a holiday. If so, the current power consumption data measured by the smart meter 5 is compared with the life pattern data B read from the storage unit 1A. In particular, the automatic power shut-off device 1 acquires current power consumption data measured by the smart meter 5 immediately before the bedtime, and determines whether or not power is used immediately before the bedtime (step S3). ).

  Current power measured by the smart meter 5 during a period in which the power consumption amounts of the life pattern data A and B read from the storage unit 1A are recognized to be equal to or greater than a certain level (period in which power is estimated to be used) When the difference between the consumption data and any one of the life pattern data A and B read from the storage unit 1A is within a certain range, or when it is recognized that power is used immediately before the bedtime (step S3) : YES), the automatic power shut-off device 1 determines that the resident is at home, and as a function of the third determination unit 1E, the occurrence time of the earthquake in the area including the house is predetermined as night. It is determined whether or not the time is in a certain time zone. Specifically, the automatic power shut-off device 1 compares earthquake occurrence time data, which is timekeeping time data when information relating to the occurrence of an earthquake, is acquired with time zone data read from the storage unit 1A (step S4).

  When the earthquake occurrence time data is included in the range of the time zone data (step S4: YES), the automatic power shut-off device 1 is in a time zone in which the occurrence time of the earthquake in the area including the house is predetermined as night. It is determined that it is time. And it determines with the seismic intensity of the earthquake which generate | occur | produced in the area containing a house being larger than the seismic intensity determined beforehand (step S2: YES), it determines with the resident being at home (step S3: YES), It is determined that the time of occurrence of the earthquake in the area including the house is a time in a predetermined time zone as night (step S4: YES), and the determination result of YES in steps S2 to S4 is obtained. As a function of the control unit 1B, the automatic shut-off device 1 enables the lighting device 3 to be lit for a certain time without shutting off the power path of the distribution board 4 (step S5). The lighting device 3 connected to the automatic power shut-off device 1 may be a device that is turned on or off in response to a control signal output from the control unit 1B, or is turned on or off in response to a resident's operation. It may be a specification device.

  The lighting device 3 can be lit for a certain time, and when the certain time has elapsed, the automatic power shut-off device 1 shuts off the power path of the distribution board 4 (step S6).

  Even if it is determined that the seismic intensity of the earthquake occurring in the area including the house is greater than the predetermined seismic intensity (step S2: YES), is it determined that the resident is not at home? If it is determined that the occurrence time of the earthquake in the area including the house is not a time in a time zone that is predetermined as night (step S4: NO), the automatic power shut-off device 1 The power supply path of the distribution board 4 is shut off without setting 3 to the lighting-enabled state (step S6).

  On the other hand, when the actual seismic intensity data is less than or equal to the reference seismic intensity data (step S2: NO), the automatic power shut-off device 1 determines that the seismic intensity of the earthquake in the area including the house is less than or equal to a predetermined seismic intensity. As a function of the first determination unit 1C, it is determined whether or not the resident is at home. The specific determination operation is the same as in step S3 described above, and the automatic power shut-off device 1 reads the current power consumption data measured by the smart meter 5 from the storage unit 1A when the current day is a weekday. Compared with the life pattern data A, if the present is a holiday, the current power consumption data measured by the smart meter 5 is compared with the life pattern data B read from the storage unit 1A (step S7).

  Current power measured by the smart meter 5 during a period in which the power consumption amounts of the life pattern data A and B read from the storage unit 1A are recognized to be equal to or greater than a certain level (period in which power is estimated to be used) When the difference between the consumption data and any one of the life pattern data A and B read from the storage unit 1A is within a certain range (step S7: YES), the automatic power shut-off device 1 allows the resident to stay at home. As a function of the control unit 1B, the lighting device 3 is in a state in which the lighting device 3 can always be lit without shutting off the power supply path of the distribution board 4 (steps S8 and S9).

  Current power consumption measured by the smart meter 5 during a period in which the power consumption amounts of the life pattern data A and B read from the storage unit 1A are recognized to be equal to or greater than a certain level (an estimated period in which power is used) When the difference between the quantity data and any one of the life pattern data A and B read from the storage unit 1A exceeds a certain range (step S7: NO), the automatic power shut-off device 1 has no resident in the house As a function of the control unit 1B, the power supply path of the distribution board 4 is kept connected without performing control that makes the lighting device 3 intentionally lightable ( Step S8).
