However, it is not preferable to notify all rooms of the same voice that conveys the occurrence of an earthquake, and notify appropriate notifications for each room, such as whether there are people in each room and the degree of risk of fire. Is desirable.

The inventor of this case tried to solve this problem by diligently examining this point. An object of the present invention is to make it possible to change the voice information notified by the alarm unit according to an event detected by a sensor unit provided in the alarm unit that notifies the occurrence of an earthquake.

In order to solve the above problems, an earthquake detection device that detects an earthquake and an alarm unit installed in each room of the building are provided, and when the earthquake detection device detects an earthquake, a sound is emitted from the notification unit of the alarm unit. In the earthquake notification system, the alarm unit is provided with a sensor unit that detects an event that occurs in the room in which the alarm unit is installed, and is provided with a determination unit that determines the sound emitted from the notification unit based on the detection information of the sensor unit. It will be an earthquake notification system.

In addition, a circuit breaker that is arranged in the distribution board and cuts off the electric circuit that supplies power to each room, and a control unit that controls to cut off the circuit breaker when the earthquake detection device detects an earthquake. , And the control unit preferably has a configuration in which the time until the circuit breaker is cut off is determined based on the information of the determination unit.

Further, it is preferable that the sensor unit is provided with at least a motion sensor that detects a person.

According to the present invention, it is possible to change the voice information notified by the alarm unit according to the event detected by the sensor unit provided in the alarm unit that notifies the occurrence of an earthquake.

It is a schematic diagram of the earthquake notification system in an embodiment. It is a schematic diagram of a building provided with an earthquake notification system. It is a flow chart which showed the flow from the detection of an earthquake to the presence or absence of the detection of a sensor.

A mode for carrying out the invention is shown below. As can be understood from FIGS. 1 and 2, the earthquake notification system 10 of the present embodiment includes an earthquake detection device 1 for detecting an earthquake and an alarm unit 2 installed in each room of the building. , Is equipped. When the earthquake detection device 1 detects an earthquake, a sound is emitted from the notification unit 24 of the alarm unit 2. Further, the alarm unit 2 includes a sensor unit 22 that detects an event that occurs in the room in which the alarm unit is installed, and also includes a determination unit 23 that determines a voice emitted from the notification unit 24 based on the detection information of the sensor unit 22. ing. Therefore, the voice information notified by the alarm unit 2 can be changed according to the event detected by the sensor unit 22 provided in the alarm unit 2 that notifies the occurrence of an earthquake.

The earthquake notification system 10 of the embodiment includes an earthquake detection unit 11 that detects the occurrence of an earthquake, and an alarm unit 2 that notifies information detected by the earthquake detection unit 11. The alarm unit 2 is installed in each room and detects an event that occurs in the room. In the embodiment, the earthquake detection unit 11 is provided in the earthquake detection device 1, and the earthquake detection device 1 includes a communication unit 12 capable of transmitting information to the alarm unit 2.

When an earthquake detection unit 11 such as a seismic relay detects an earthquake, a detection signal is transmitted to each alarm unit 2, and the alarm unit 2 that receives the detection signal notifies that an earthquake has occurred.

The alarm units 2 dispersed in the building include a communication unit 21, a sensor unit 22, a determination unit 23, a notification unit 24, and a stop unit 25. When the earthquake detection unit 11 detects an earthquake, the communication unit 21 of the alarm unit 2 receives a detection signal transmitted from the communication unit 12 provided in the earthquake detection device 1 to the alarm unit 2. Further, the determination result of the determination unit 23 is transmitted to the control device 3 that controls the opening and closing of the circuit breaker 51 provided in the electric circuit to each room. The control device 3 includes a control unit 31 that controls the circuit breaker 51 to be cut off when the earthquake detection device 1 detects an earthquake.

The sensor unit 22 is a sensor used for the purpose of disaster prevention, such as a motion sensor that detects a person, a fire sensor that detects a fire, a smoke sensor that detects smoke, and a motion sensor that detects the movement of a person. It is equipped with a sensor that detects an event that occurs in the vicinity of the alarm unit 2. If a motion sensor is used, it is possible to detect whether or not there is a person in the room. If a fire sensor is used, it is possible to detect whether or not the heater 92 is used and whether or not a fire has occurred. If a smoke sensor is used, it is possible to detect whether or not smoke is generated due to a fire or the like. A motion sensor can be used to detect whether a person in a room is moving or stationary. If a motion sensor is used to detect a person for a certain period of time, it is possible to estimate whether or not a person can evacuate. Therefore, it is possible to configure the notification according to the estimation result. It is desirable that the sensor unit 22 is configured to include at least a motion sensor that detects a person.

The determination unit 23 makes a determination based on the reception of the detection signal by the communication unit 21 and the detection information of the sensor unit 22. Based on the information of the determination unit 23, the control unit 31 determines the time until the circuit breaker 51 is cut off.

The notification unit 24 notifies according to the determination result of the determination unit 23. For example, if the alarm unit 2 receives that the sensor unit 22 has not detected an earthquake and the earthquake detection unit 11 has detected an earthquake, it may notify that "an earthquake has occurred." In addition, when the human sensor of the sensor unit 22 detects and the alarm unit 2 receives that the earthquake detection unit 11 has detected an earthquake, "an earthquake has occurred. Ensure your safety and evacuate. Please let me know. " In addition, when the fire sensor of the sensor unit 22 detects and the alarm unit 2 receives that the earthquake detection unit 11 has detected an earthquake, it notifies that "an earthquake has occurred. Please check the source of the fire." Just do it. The content to be notified is not particularly limited to such an example.

The stop unit 25 is for stopping the sound and the like emitted by the notification unit 24. This is effective when the detection of the earthquake detection unit 11 is a false detection. For example, the voice or the like may be stopped by pressing a switch provided as the stop unit 25.

The control unit 31 that controls the opening and closing of the circuit breaker 51 may be installed in the device provided with the earthquake detection unit 11, or may be installed in the control device 3 provided separately from the earthquake detection device 1. It doesn't matter. For example, the distribution board 5 is provided with an earthquake detection unit 11 and a control unit 31, and a communication unit 12 connecting the earthquake detection unit 11 and the alarm unit 2 and a communication unit 32 connecting the control unit 31 and the alarm unit 2 are common. It is preferable to make it.

The circuit breaker 51 is cut off by the occurrence of an earthquake, rather than being the same in all rooms, the cutoff time is set for each room depending on whether there are people in each room and whether there is a risk of a secondary disaster such as a fire. It is preferable to determine. Therefore, the control device 3 receives the determination result of the alarm unit 2 in the communication unit 32, and the control unit 31 determines the cutoff time of the circuit breaker 51 based on the received content. For example, if there is no detection by the sensor unit 22 and the communication unit 32 of the control device 3 receives that the earthquake detection unit 11 has detected an earthquake, the cutoff time may be set to a normal time (for example, 3 minutes). Further, when the motion sensor of the sensor unit 22 detects the earthquake and the communication unit 32 of the control device 3 receives that the earthquake detection unit 11 has detected an earthquake, the cutoff time is extended from the normal time (for example, 10 minutes). It should be decided. Further, when the fire sensor of the sensor unit 22 detects and the communication unit 32 of the control device 3 receives that the earthquake detection unit 11 has detected an earthquake, the cutoff time is shortened (for example, 30 seconds) from the normal time. It should be decided. The cutoff time is not particularly limited to such an example.

Further, when the cutoff time of the circuit breaker 51 is approaching, the sensor unit 22 may detect an event occurring in the vicinity of the alarm unit 2 again. For example, when the cutoff time is set to 10 minutes, the sensor unit 22 may detect an event occurring in the vicinity of the alarm unit 2 again after 9 minutes and 30 seconds have elapsed from the detection. At that time, if the presence of a person is detected by the motion sensor again, the cutoff time may be extended again.

Further, the sensor unit 22 may always continue to detect the presence of a person, and as long as the presence of a person is continuously detected, the cutoff time may be continuously extended. Further, by equipping any device or unit with a means for communicating information on the presence of a person to the outside, the information on the presence of a person may be utilized for rescue activities.

Here, the flow from the earthquake detection to the determination by the determination unit 23 will be described by taking the flow diagram shown in FIG. 3 as an example. First, it is confirmed whether the earthquake detection unit 11 has detected an earthquake (S101). If no earthquake is detected, step 101 is repeated. When an earthquake is detected, a detection signal is transmitted to the alarm unit 2 (S102). The alarm unit 2 receives this detection signal (S103). Next, it is confirmed whether the sensor unit 22 of the alarm unit 2 has detected the event (S104). When the sensor unit 22 does not detect an event, the notification unit 24 notifies only the earthquake occurrence information (S107).

When the sensor unit 22 detects an event, it is confirmed which sensor has detected the event. For example, it is confirmed whether or not the sensor A has detected it (S105). If the sensor A has detected it, a determination is made according to the detection result (S106). For example, when sensor A, which is a motion sensor, detects it, people in the detected area should ensure their own safety, notify a voice that allows them to evacuate, or secure a lamp in the room until they can evacuate. The circuit breaker 51 may be controlled.

If the sensor A has not detected it in step 105, it is confirmed whether or not the sensor B has detected it (S108). If the sensor B has detected it, a determination is made according to the detection result (S109). For example, when the sensor B, which is a fire sensor, detects a fire, in order to prevent the occurrence of a fire, a sound for confirming the source of the fire may be generated, or the circuit breaker 51 may be controlled so as to cut off the electric power. The confirmations such as step 105 and step 108 may be repeated for the number of sensors constituting the sensor unit 22.

In the flow chart shown in FIG. 3, the presence / absence of detection of each sensor is individually determined, but a plurality of sensors may be detected. In such a case, it is preferable to perform combined notification and control. For example, when the motion sensor and the flame sensor are detected at the same time, after ensuring the safety of the surroundings, a sound indicating that the source of the fire is confirmed may be emitted, or the heater 92 or the like may be used as the source of the fire. The circuit breaker 51 may be controlled so as to cut off only the supplied power.

Although one embodiment has been described above, the present invention is not limited to the above embodiment and can be in various modes. For example, if it is determined whether or not one sensor has detected it, it is possible to determine whether or not the next sensor has detected it.

Further, the alarm unit may be provided with a light emitting unit that generates strong light such as strobe light at the same time as voice notification when the sensor detects it. By doing so, it is possible to notify the danger to the noise caused by the collapse of the house at the time of an earthquake and the hearing impaired.
