  The control unit 45 includes a terminal-side detection control unit 45a and a terminal-side delivery control unit 45b in terms of functional concept. The terminal-side detection control unit 45a is a terminal-side detection control unit that causes the output unit 42 to output an alarm based on the detection result of the abnormality detection unit 41. The terminal-side delivery control unit 45 b is a terminal-side delivery control unit that outputs the disaster prevention information specified by the disaster prevention information ID via the output unit 42 when the communication unit 43 receives the disaster prevention information ID. Specific processing performed by the terminal-side detection control unit 45a and the terminal-side distribution control unit 45b will be described later.

(processing)
Next, processing executed by the disaster prevention information distribution system 1 configured as described above will be described.

(Processing-electric energy measurement processing)
First, the power amount measurement process will be described. This process is a process for measuring the power consumption of the dwelling unit 3 and transmitting it to the center device 10. In this process, the power measuring unit 22 of the smart meter 20 of each dwelling unit 3 measures the power consumption of the dwelling unit 3 in which the smart meter 20 is installed at a predetermined period by a known method, and the measured power usage is calculated. Output to the control unit 24. The device-side measurement control unit 24 a of the control unit 24 transmits the power usage amount and the smart meter ID stored in the storage unit 23 to the center device 10 via the communication unit 21. When the power usage amount and the smart meter ID are received via the communication unit 12, the control unit 15 of the center apparatus 10 associates the power usage amount and the smart meter ID with each other in the storage unit 14. Remember. Then, at an arbitrary timing thereafter, the user of the smart meter 20 is charged for the electric power charge by an arbitrary method based on the power usage amount and the smart meter ID. However, the details of the electric energy measurement process can be performed in the same manner as the electric energy measurement process in the known smart meter 20, and thus the description thereof is omitted.

(Processing-Abnormality detection processing)
Next, the abnormality detection process will be described. This process is a process for detecting an abnormality in the monitoring area in the dwelling unit 3 and outputting an alarm. In this process, the abnormality detection unit 41 of each disaster prevention terminal 40 of each dwelling unit 3 detects the abnormality of the monitoring area in the dwelling unit 3 in which the disaster prevention terminal 40 is installed at a predetermined abnormality detection cycle by a known method. The result is output to the control unit 45. The terminal-side detection control unit 45a of the control unit 45 determines the presence or absence of abnormality in the monitoring region by comparing the detection result with a predetermined abnormality determination threshold value, and when determining that there is an abnormality, the output unit Causes the alarm to be output. However, the details of the abnormality detection process can be performed in the same manner as the abnormality detection process in the known disaster prevention terminal 40, and thus the description thereof is omitted.

  As modes for performing the abnormality detection processing, there are a “normal mode” and a “disaster prevention mode”, and these two modes can be switched alternatively. “Normal mode” means normal time (specifically, before the disaster prevention terminal 40 receives the disaster prevention information ID or after a predetermined time (for example, 30 minutes) has elapsed since the disaster prevention terminal 40 received the disaster prevention information ID). The possibility of misreporting by reducing the power consumption of the disaster prevention terminal 40 or increasing the abnormality determination threshold by increasing the abnormality detection period compared to the disaster prevention mode. It is a mode to reduce. The “disaster prevention mode” is a mode selected at the time of disaster prevention (specifically, a predetermined time (for example, 30 minutes) after the disaster prevention terminal 40 receives the disaster prevention information ID), compared with the normal mode. In this mode, the abnormality is detected early by shortening the abnormality detection cycle or reducing the abnormality determination threshold. When the disaster prevention terminal 40 is turned on, the normal mode is set as the default mode, and in the disaster prevention information distribution process described later, switching to the disaster prevention mode is automatically performed.

(Processing-Disaster prevention information distribution processing)
Next, disaster prevention information distribution processing will be described. This process is a process for distributing disaster prevention information from the center apparatus 10 to the dwelling unit 3, and is repeatedly executed by these devices after powering on the center apparatus 10, the smart meter 20, and the disaster prevention terminal 40. . FIG. 7 is a flowchart of disaster prevention information distribution processing. Hereinafter, “step” is abbreviated as “SA”.

  First, the center side distribution control unit 15a of the center apparatus 10 determines whether or not a distribution timing for distributing disaster prevention information has arrived (SA1). This determination can be made based on an arbitrary criterion. For example, the type of the cause event, the occurrence state of the cause event, the occurrence point of the cause event, and the occurrence level of the cause event are input via the input unit. In this case, it is determined that this distribution timing has arrived. For example, the user of the center device 10 may manually input various types of information related to the cause event, or may be automatically input from an external system such as an emergency earthquake warning. It may be. However, a timing based on a predetermined reference different from the timing at which these various types of information are input may be set as the delivery timing.

  Next, when it is determined that the distribution timing has arrived (SA1, Yes), the distribution target specifying unit 15b of the center device 10 acquires the smart meter ID of the smart meter 20 to which the disaster prevention information should be distributed (SA2). For example, when the distribution target specifying unit 15b inputs the cause event type, the cause event occurrence state, the cause event occurrence point, and the cause event occurrence level via the input unit before and after SA1. , By referring to the disaster prevention information DB 14b based on each of these information, specify the area where the disaster prevention information should be distributed, and by referring to the map DB 14c based on the specified area, included in the specified area The smart meter ID of the smart meter 20 installed in the dwelling unit 3 of the specified address is acquired by specifying the address of the specified dwelling unit 3 and referring to the smart meter information DB 14a based on the specified address. As an example, when the cause event type = “earthquake”, the cause event occurrence status = “alarm”, the cause event occurrence location = “Tokyo”, and the cause event occurrence level = “seismic intensity 5” Refers to the disaster prevention information in FIG. 4 and specifies the area to which the disaster prevention information should be distributed = “Tokyo”. Then, the address of the dwelling unit 3 located in the specified area = “Tokyo” is specified with reference to the map DB 14c. Furthermore, the smart meter ID of the smart meter 20 installed in the dwelling unit 3 at the address is acquired with reference to the smart meter information DB 14a.

  Next, the distribution content specifying unit 15c of the center device 10 acquires the disaster prevention information ID corresponding to the content of the disaster prevention information to be distributed (SA3). For example, the delivery content specifying unit 15c may be configured to input the cause event type, the cause event occurrence state, the cause event occurrence point, and the cause event occurrence level via the input unit before or after SA1. The contents of the disaster prevention information are specified by referring to the disaster prevention information DB 14b based on these pieces of information. However, in the present embodiment, the content of the disaster prevention information is specified by specifying the disaster prevention information ID. As an example, when the cause event type = “earthquake”, the cause event occurrence status = “alarm”, the cause event occurrence location = “Tokyo”, and the cause event occurrence level = “seismic intensity 5” Refers to the disaster prevention information of FIG. 4 and acquires the content of the disaster prevention information = “disaster prevention information ID”.

  And the center side delivery control part 15a of the center apparatus 10 transmits smart meter ID acquired in SA2, and disaster prevention information ID acquired in SA3 (SA4). For example, the center side distribution control unit 15 a generates a disaster prevention signal including the smart meter ID and the disaster prevention information ID, and transmits the generated disaster prevention signal via the communication unit 13.

  On the other hand, the device-side distribution control unit 24b of the smart meter 20 monitors the reception state of the signal transmitted from the center device 10 and receives the disaster prevention signal transmitted from the center device 10 via the communication unit 21. (SA5, Yes), it is determined whether the smart meter ID included in the disaster prevention signal matches the smart meter ID stored in its own storage unit 23 (SA6). And when it does not correspond (SA6, No), the said disaster prevention signal is not a signal transmitted to self, and returns to SA5. On the other hand, if they match (SA6, Yes), the disaster prevention signal is transmitted to itself, and the disaster prevention information ID included in the disaster prevention signal is transmitted via the communication unit 21 (SA7). .

  On the other hand, the terminal-side delivery control unit 45b of the disaster prevention terminal 40 monitors the reception state of the signal transmitted from the smart meter 20, and has received the disaster prevention information ID transmitted from the smart meter 20 via the communication unit 43. In the case (SA8, Yes), the disaster prevention information specified by the disaster prevention information ID is output via the output unit 42 (SA9). For example, the terminal-side delivery control unit 45b acquires the sound data of the disaster prevention information corresponding to the disaster prevention information ID from the storage unit 44, and outputs the acquired sound data from the output unit 42 as a sound.

  As a result, sound data corresponding to the type of the cause event, the occurrence state of the cause event, the occurrence point of the cause event, and the occurrence level of the cause event are output from each disaster prevention terminal 40 of the dwelling unit 3. For example, if the cause event type = “earthquake”, the cause event occurrence status = “alarm”, the cause event occurrence location = “Tokyo”, and the cause event occurrence level = “seismic intensity 5”, “earthquake” Voice data is output saying “This is an alarm. Seismic intensity 5. Please prepare for shaking.” Or, when the cause event type is “tsunami”, the cause event occurrence status is “alarm”, the cause event occurrence point is “Tokyo Bay”, and the cause event occurrence level is “wave height of 5 or more to less than 10 m” Will output voice data saying "Tsunami warning. Tsunami of up to 10m may arrive. Please evacuate to the hill."

  Moreover, when the disaster prevention information ID is received in SA10, the terminal side distribution control unit 45b of the disaster prevention terminal 40 sets the mode of the abnormality detection process based on the detection result of the abnormality detection unit 41 before or after SA11 to the normal mode. Switch to disaster prevention mode (SA10). Although the specific object and method of this switching are arbitrary, for example, when the received disaster prevention information ID corresponds to the cause event type = “earthquake” (in the example of disaster prevention information in FIG. 4) If the first symbol of the disaster prevention information ID is “J”), an increase in the number of fires caused by an earthquake is expected, so it is necessary to detect the abnormality early by switching the normal mode to the disaster prevention mode. Make it possible.

  Thereafter, the terminal-side distribution control unit 45b determines whether or not a predetermined stop condition is satisfied (SA11). Here, the “stop condition” is a condition for stopping the output of the disaster prevention information started at SA9 in the disaster prevention terminal 40, and a condition for returning the disaster prevention mode switched at SA10 to the normal mode. . That is, for example, when a disaster in which a dangerous state continues for a relatively long time, such as a tsunami, is predicted or occurs, it is preferable that a warning to the user is also performed for a relatively long time. For this reason, the terminal-side delivery control unit 45b continues the alarm to the user by continuing the output of the disaster prevention information until it is determined that the stop condition is satisfied, and maintains the disaster prevention mode. Continue early detection. Although the specific content of this stop condition is arbitrary, for example, when the disaster prevention terminal 40 is provided with an input unit such as an operation button, the terminal-side distribution control unit 45b performs a predetermined method via this input unit. When the alarm stop operation is performed, it is determined that the stop condition is satisfied. Or you may make it transmit the disaster prevention stop signal containing smart meter ID from the center apparatus 10, and the smart meter 20 transmits the disaster prevention stop signal containing smart meter ID which corresponds to own smart meter ID to the disaster prevention terminal 40. When the disaster prevention terminal 40 receives the disaster prevention stop signal, the terminal-side delivery control unit 45b determines that the stop condition is satisfied. Or the terminal side delivery control part 45b determines with the stop condition having been satisfied, when predetermined disaster prevention state continuation time passes after starting the output of disaster prevention information by SA9. In this case, the duration of the disaster prevention state may be changed according to the type of the cause event. For example, when type = earthquake, 5 minutes, type = tsunami, 2 hours, type = heavy rain Set to 1 hour. Alternatively, these various stop conditions may be combined.

  Alternatively, whether or not the stop condition is satisfied may be determined based on the detection result by the abnormality detection unit 41. Although the type of the abnormality detection unit 41 referred to at this time is arbitrary, for example, a detection result by the abnormality detection unit 41 of the human sensor is referred to. For example, when the disaster prevention terminal 40 including the terminal side distribution control unit 45b is a human sensor, the terminal side distribution control unit 45b refers to the human body detection result by the abnormality detection unit 41 included in the disaster prevention terminal 40. Or when the disaster prevention terminal 40 provided with the said terminal side delivery control part 45b is not a human sensor (for example, when it is a fire detector or a gas leak alarm), the terminal side delivery control part 45b is said disaster prevention terminal 40 concerned. The human body detection result by the abnormality detection part 41 with which the human sensor which is the other disaster prevention terminal 40 installed in the same monitoring area | region is equipped is referred. And when a human body is detected, by determining that the stop condition is not satisfied, the output of disaster prevention information is continued, and the detected person is informed of the danger. On the other hand, when a human body is not detected, after starting the output of disaster prevention information in SA9, when a predetermined disaster prevention state duration has elapsed, it is determined that the stop condition has been satisfied, and in SA12 described later The output of the disaster prevention information is stopped, the continuation of unnecessary output is avoided, and the battery consumption of the disaster prevention terminal 40 is reduced. Alternatively, the determination of the stop condition may be combined with the determination of the stop condition according to the type of the cause event described above. For example, in the case of type = earthquake or tsunami, the human body is detected because the risk is particularly high. Regardless of whether or not it has been stopped, it is determined that the stop condition is not satisfied, and if the type = heavy rain, the risk is relatively low, so the stop condition is satisfied only when a human body is detected. You may make it determine with not.

  If the terminal-side distribution control unit 45b determines that the predetermined stop condition has been satisfied (SA11, Yes), the terminal-side distribution control unit 45b stops outputting the disaster prevention information started at SA9 (SA12) and switched at SA10. The disaster prevention mode is returned to the normal mode (SA13). This completes the disaster prevention information distribution process.

(About disaster prevention information)
Some information of disaster prevention information may be omitted, for example, if the purpose is to specify the area where disaster prevention information should be distributed, the type of cause event of disaster prevention information, the occurrence point of the cause event of disaster prevention information, The disaster prevention information (area information) is configured so as to include only the area to which the disaster prevention information should be distributed, and the distribution target specifying unit 15b receives the type of the cause event and the occurrence point of the cause event via the input unit 11 In some cases, the disaster prevention information may be identified by referring to the disaster prevention information based on these pieces of information. Also, for example, for the purpose of identifying the content of disaster prevention information, the type of cause event of disaster prevention information, the location of the cause event of disaster prevention information, the occurrence level of the cause event of disaster prevention information, and disaster prevention information are distributed. Configure the disaster prevention information (content information) to include only the area where the disaster prevention information cause event and the area where disaster prevention information should be delivered, the type of the cause event, the occurrence point of the cause event of the disaster prevention information, When the occurrence level of the cause event of the disaster prevention information and the area where the disaster prevention information should be distributed are specified, the disaster prevention information should be identified by referring to the disaster prevention information based on each information. Also good.

(About control in units of units)
In addition to the control for each dwelling unit, or instead of the control for each dwelling unit, the plurality of disaster prevention terminals 40 provided in the dwelling unit may be individually controlled. For example, in each disaster prevention terminal 40, disaster prevention terminal identification information for uniquely identifying each disaster prevention terminal 40 is set, and when the disaster prevention signal is transmitted from the center device 10, the disaster prevention terminal outputs the disaster prevention information. 40 disaster prevention terminal identification information is included in the disaster prevention signal and transmitted. Each disaster prevention terminal 40 outputs disaster prevention information only when the disaster prevention terminal identification information transmitted from the smart meter 20 matches the disaster prevention terminal identification information set for itself.

(About disaster prevention information identification information)
Instead of transmitting the disaster prevention information ID from the center device 10 to the disaster prevention terminal 40, the center device 10 may transmit the content of disaster prevention information itself (for example, voice data) to the disaster prevention terminal 40. The content of the disaster prevention information is not limited to voice data. For example, the indicator lamp in the output unit 42 of the disaster prevention terminal 40 blinks or lights at a predetermined cycle or a predetermined interval, or a monitor is displayed on the output unit 42 of the disaster prevention terminal 40. If provided, characters and images may be displayed on the monitor. Moreover, you may make it output the disaster prevention information of a different content according to the kind of disaster prevention terminal 40. FIG.

(About modes)
The contents of each of the normal mode and the disaster prevention mode can be arbitrarily changed. For example, in the normal mode, the sleep mode that reduces power consumption by stopping the functions other than the reception function of the disaster prevention information ID is set. May be an operation mode in which all functions are activated. The mode switching may be omitted.

(About judgment of stop condition)
When determining whether or not the stop condition is satisfied based on the detection result by the abnormality detection unit 41, the detection is not limited to the detection result by the abnormality detection unit 41 of the human sensor, but is detected by another type of abnormality detection unit 41. You may refer to the result. For example, if the cause event type is an earthquake, the damage caused by the cause event is expected to increase further due to the occurrence of a fire, so it stops only when a fire is detected by the abnormality detector 41 of the fire detector. If it is judged that the conditions are not satisfied, the disaster prevention information is output continuously. If the cause event type is tsunami or heavy rain, the damage caused by the cause event is not directly related to the occurrence of the fire. The stop condition may be determined by excluding whether or not a fire is detected by the abnormality detection unit 41.

(Additional effects)
According to the disaster prevention information distribution system described in appendix 1, a power measurement device installed in each dwelling unit to perform power measurement, and a disaster prevention terminal installed in each dwelling unit to detect an abnormality and output an alarm Since it is possible to output disaster prevention information in the dwelling unit, it is possible to distribute the disaster prevention information in units of dwelling units without requiring a dedicated terminal for performing disaster prevention information. In particular, in conventional disaster prevention information distribution systems equipped with in-house receivers, it is assumed that one in-house receiver is installed in one dwelling unit, so there are places where it is difficult to hear disaster prevention information. However, there are places where it is difficult to hear disaster prevention information by outputting disaster prevention information through such disaster prevention terminals because there are many cases where disaster prevention terminals are installed in one dwelling unit. The possibility can be reduced.

  According to the disaster prevention information distribution system described in appendix 2, the power measurement device installed in the dwelling unit located in the area where the disaster prevention information should be distributed is automatically based on the type and location of the cause of the disaster prevention information. Therefore, the disaster prevention information can be easily and quickly distributed to the power measuring device applied to the type and the occurrence point of the cause event, and the disaster prevention information can be distributed more effectively.

  According to the disaster prevention information distribution system described in appendix 3, the content of the disaster prevention information is automatically identified based on the type of the cause event of the disaster prevention information, the occurrence point, and the occurrence level. And it becomes possible to distribute the disaster prevention information of the contents applied to the occurrence point and the occurrence level easily and quickly, and the disaster prevention information can be distributed more effectively.

  According to the disaster prevention information distribution system described in appendix 4, since the disaster prevention information is acquired and output at the disaster prevention terminal based on the disaster prevention information identification information transmitted from the center device, the disaster prevention information itself is transmitted from the center device. This eliminates the need for communication load.

  According to the disaster prevention information distribution system described in appendix 5, when disaster prevention specific information is received, the abnormality detection processing mode is switched from the normal mode to the disaster prevention mode. It becomes possible to carry out combined disaster prevention measures together with the distribution of disaster prevention information.

  According to the disaster prevention information distribution system described in appendix 6, the disaster prevention state is maintained for a suitable time according to the type of the cause event by continuing the output of the disaster prevention information for the duration of the disaster prevention state corresponding to the type of the cause event. For example, when a causal event occurs where the danger continues for a relatively long time, the disaster prevention information is continuously output for a relatively long time to notify the user of the risk. When a cause event that eliminates the danger in a relatively short time occurs, it is possible to prevent the user from being bothered by automatically stopping the output of the disaster prevention information in a relatively short time.

  According to the disaster prevention terminal described in appendix 7, the determination is made based on the detection result of the abnormality detection means of the disaster prevention terminal, and the output of the disaster prevention information is stopped. Therefore, by notifying the detected person of the danger reliably, or by stopping the output of disaster prevention information after a certain period of time in dwelling units where there are no people, The output can be stopped at a timing according to the state of the dwelling unit, such as reducing the battery consumption.
