And a signal including the evacuation map is transmitted to the monitoring area by the transmission antenna unit 34. Thereby, the user who exists in the monitoring area | region of each sensor 30 can acquire evacuation information, and can evacuate based on the acquired evacuation information. Here, the transmission method by the radio signal of the transmission antenna unit 34 is arbitrary. For example, the control unit 36 of the sensor 30 sends a signal including evacuation information and a signal including the evacuation map by push mail by the transmission antenna unit 34. It may be transmitted to the monitoring area. Thereby, the user who exists in the monitoring area | region of each sensor 30 can receive evacuation information in real time, and can save the effort which the said user himself operates a portable terminal in order to receive evacuation information.

  In addition, after the processing of SB7, the control unit 45 of the receiver 40 causes the communication unit 43 to transmit the notification signal and the GPS signal received at SB3 to the fire department or the police station (SB10). At the same time, the control unit 45 of the receiver 40 converts the map information stored in the map information DB 46a and corresponding to the position specified by the position specifying unit 45a by a known method. Then, the communication unit 43 transmits a signal including the converted map information to the fire department or the police station (SB10). As a result, it is possible to notify an external organization such as a fire department or police station that an abnormality has been detected in the monitoring area, and at the same time, it is possible to send detailed information regarding the location where the abnormality has been detected. This makes it easier to take measures against area abnormalities.

(effect)
As described above, according to the present embodiment, the sensor 30 receives a signal including the position information transmitted from the receiver 40, stores the position information included in the received signal in the position information table 37a, Since a signal including the position information stored in the position information table 37a is transmitted to the monitoring area as a radio signal, it is possible to omit newly providing a dedicated device for transmitting the position information to the monitoring area. The configuration of the system can be simplified and the installation cost can be reduced.

  In addition, when detecting an abnormality, the sensor 30 transmits a notification signal to the receiver 40 and transmits a signal including the position information stored in the position information table 37a to the receiver 40. 40 can acquire the information in which the abnormality is detected and the position information of the sensor 30 that has issued the alarm, warn the user in the monitoring area of each sensor 30, or send it to the outside of the system. A report regarding the abnormality can be made.

  In addition, when the sensor 30 receives evacuation information from the receiver 40, the sensor 30 transmits a signal including the received evacuation information to the monitoring area using a radio signal. Evacuation information can be acquired, and evacuation can be performed based on the acquired evacuation information.

  In addition, when the evacuation information is received from the receiver 40, the sensor 30 transmits a signal including the evacuation information received from the receiver 40 to the monitoring area by push mail. The user in can receive the evacuation information in real time and can save the user from operating the portable terminal to receive the evacuation information.

  In addition, when receiving a notification signal from the sensor 30, the receiver 40 transmits a signal including the notification signal and position information received from the sensor 30 to the outside of the alarm system 1, and map information. Since the map information stored in the DB 46a and including the map information corresponding to the position specified by the position specifying unit 45a is transmitted to the outside of the alarm system 1, an external organization such as a fire department or a police station In addition, it is possible to transmit the detailed information regarding the position where the abnormality is detected at the same time that the abnormality is detected in the monitoring area, and it becomes easy for the external organization to take measures against the abnormality.

  The GPS receiver 20 receives a GPS signal transmitted from a satellite and transmits the received GPS signal to the receiver 40. The receiver 40 receives the GPS signal transmitted from each GPS receiver 20. Then, each received GPS signal is transmitted to each sensor 30, and the sensor 30 receives the GPS signal transmitted from the receiver 40, and the position information included in the received signal is stored in the position information table 37a. Since it memorize | stores, the sensor 30 can transmit the positional information contained in a GPS signal to the monitoring area | region of the said sensor 30, and can provide a highly accurate positional information with respect to a user.
