Considering the cause of the fire, negligence and other negligence are the most common, followed by forgetting to extinguish the fire in the event of an earthquake. In particular, a fire during an earthquake is likely to cause a major disaster. For this reason, the processing operation in the following disaster prevention system will be described for the case of preventing a fire in the event of an earthquake or emergency.

  First, the seismic intensity observation device (30-1 to N) always measures seismic intensity data for crustal vibration, and the seismic intensity observation device for identifying the seismic intensity observation device (30-1 to N) from the measured seismic intensity data. It transmits to the disaster prevention command device (20) in real time together with the IP addresses (30-1 to N) (step A1, step A2).

  The disaster prevention instruction device (20) receives the seismic intensity data and the IP addresses of the seismic intensity observation devices (30-1 to N) from the seismic intensity observation devices (30-1 to N), and the disaster prevention instruction device (20). Is based on the IP address of the seismic intensity observation device (30-1 to N) received from the seismic intensity observation device (30-1 to N) using the data processing unit (201) of the disaster prevention device (20). The database (202) suggested in FIG. 3 is searched, and the seismic intensity observation devices (30-1 to N) stored in the database (202) are associated with the IP addresses of the seismic intensity observation devices (30-1 to N). ) Information (location information of the seismic intensity observation devices (30-1 to N), etc.) is acquired and installed in any location based on the acquired information of the seismic intensity observation devices (30-1 to N) Seismic intensity observation equipment (30-1 to N) Seismic data is to identify whether the transmitted.

  The disaster prevention command device (20) uses the data processing unit (201) included in the disaster prevention command device (20) to receive the seismic intensity observation device (30-) received from the seismic intensity observation devices (30-1 to N). 1 to N), the IP address of the seismic intensity observation device (30-1 to N) received from the seismic intensity observation device (30-1 to N) by searching the database (202) suggested in FIG. Obtain the IP address of the disaster prevention device (10-1 to N) stored in the database (202) and the information on the partition area where the disaster prevention device (10-1 to N) is installed. The seismic intensity observation devices (30-1 to N) received from the seismic intensity observation devices (30-1 to N) on the basis of the acquired IP addresses of the disaster prevention devices (10-1 to N) and the area information. ) IP address And the disaster prevention device (10-1~N), so that the disaster prevention device (10-1~N) to identify the partition areas that have been installed.

  At this time, the disaster prevention command device (20) is associated with each disaster prevention device (10-1 to N) based on the seismic intensity data received from the seismic intensity observation devices (30-1 to N). Average seismic intensity data for each of the seismic intensity observation devices (30-1 to N) managed for each is calculated (step A4). For example, in the database (202) suggested in FIG. 3, a plurality of seismic intensity observation devices (30-1 to M) managed in the partition area 1 in association with the IP address of one disaster prevention device (10-1). Average seismic intensity data of (M is an arbitrary integer (1 ≦ M <N))) is calculated.

The thermal device (50) shuts off the fire source immediately so that the fire source is shut off immediately only when a shutdown signal is received from the specific disaster prevention device (10-1 to N). The frequency range of the signal is set to the thermal device (50), and when the thermal device (50) receives the cutoff signal from the disaster prevention device (10-1 to N), the frequency of the received cutoff signal is However, when it determines with it being the range of the specific frequency currently set to the thermal equipment (50), the thermal equipment (50) will perform an immediate interruption | blocking of a fire source. Thereby, a thermal apparatus (50) will carry out immediate interruption | blocking of a fire source only with respect to the interruption | blocking signal received from the specific disaster prevention apparatus (10-1 to N).

  As described above, the disaster prevention system according to the present invention is based on the seismic intensity data received by the disaster prevention instruction device (20) from the seismic intensity observation devices (30-1 to N). If the seismic intensity threshold for determining whether or not the seismic intensity threshold has been exceeded is determined, and the seismic intensity data determines that the seismic intensity threshold has been exceeded, the disaster prevention device (20) The earthquake prevention command device (20) determines that an earthquake has occurred in the surrounding area where seismic intensity observation devices (30-1 to N) that have received seismic intensity data exceeding the threshold value are installed, and the earthquake has occurred. The disaster prevention device (10-1 to N) transmits a cutoff signal transmission request to the determined disaster prevention device (10-1 to N), and the disaster prevention device (10-1 to N) issues a cutoff signal from the disaster prevention command device (20). When a request is received, The blocking signal wirelessly transmitted Te, thermal device (50), when a disaster prevention device (10-1～N) receives a blocking signal that originates, will perform an immediate interruption of the origin of fire. Even in the event of an emergency, the disaster command center device (40) identifies the disaster prevention devices (10-1 to N) that perform the disaster prevention processing, and the identified disaster prevention devices (10-1 to N) are identified. A disaster prevention command request for performing disaster prevention processing is transmitted to the disaster prevention command device (20), and the disaster prevention command device (20) receives the disaster prevention command request from the disaster command center device (40), and the disaster Based on the prevention command request, the disaster prevention device (10-1 to N) for performing the disaster prevention processing is identified, and the identified disaster prevention device (10-1 to N) is blocked for performing the disaster prevention processing. When the transmission request for the signal is transmitted and the disaster prevention device (10-1 to N) receives the transmission request for the cutoff signal from the disaster prevention command device (20), the cutoff signal is wirelessly transmitted to the specific partition area. Send and heat equipment (50) disaster prevention When location (10-1~N) receives a blocking signal that originates, will perform an immediate interruption of the origin of fire. As a result, when the thermal device (50) receives a cutoff signal transmitted wirelessly by the disaster prevention devices (10-1 to N) in the event of an earthquake or other emergency, the fire source is immediately shut off simultaneously. Since it can be performed, it is possible to reliably prevent a fire regardless of the fuel such as city gas, propane gas, or kerosene.
