  Further, the gas meter 1 has a function of shutting off the gas when the seismic intensity is higher than a predetermined seismic intensity. If the seismic detecting means 306 is at a level indicating a predetermined seismic intensity, the meter control means 308 controls the valve shutting means 307. Control and shut off gas. When the gas is shut off, the gas meter 1 informs the center of the gas company that a gas shut-off event (gas abnormality) has occurred (not shown).

  When an earthquake is detected in the gas meter 1 or a gas interruption occurs due to the earthquake, a telegram for notifying the occurrence of an abnormality is generated by the meter control means 308 and transmitted to the wireless device 1d and transmitted to the wireless communication means 301 of the communication terminal 2 via wireless communication. (Step 602).

  The message received by the wireless communication unit 301 is subjected to determination processing by the notification information determination unit 302 by analyzing the notified message content.

  The earthquake information acquisition unit 304 generates an earthquake information acquisition request message, controls the outside communication unit 303, and transmits the message to the server 4 through the Internet 3. The server 4 analyzes the contents of the electronic message, and when the content is an earthquake information acquisition request, the information recorded in the earthquake information database 505 is set in a response electronic message and is received by the communication terminal 2 (step 603).

  The communication terminal 2 that has acquired the earthquake information notifies the user of the earthquake information acquired by the notification unit 305 with characters, images, sounds, and the like (step 604). Further, when a gas shut-off occurs due to an earthquake, the notifying means 305 notifies the gas abnormality, the shut-off valve return method, and the like.

  In addition to providing information to the communication terminal 2, it is also possible to distribute earthquake information in a timely manner to the user's mobile phone 5 using this system by e-mail.

  Note that the shaking level that is detected and notified by the gas meter 1 is set in advance to a predetermined value.

  At this time, the priority of earthquake information acquisition to the server 4 of the out-of-home communication means 303 (for example, providing a plurality of waiting times depending on the shaking level) may be provided according to the shaking level of the earthquake. Earthquake information may be acquired with the gas cutoff abnormality information as the highest priority. By providing the priority of earthquake information acquisition in this way, centralized access to the server 4 when an earthquake occurs can be distributed and alleviated.

  Although the communication terminal 2 and the server 4 have been described as being connected via the Internet 3, the present invention is not limited to this, and the communication line is a telephone line, ISDN, ADSL, CATV, optical cable (FTTH), wireless LAN, Ethernet ( Registered trademark) or the like.

If the notification information determination unit 302 determines that the information is earthquake detection information or gas cutoff abnormality information due to an earthquake, the radio reception unit 701 is operated, and is tuned to a predetermined radio frequency set in advance to be in a radio reception state. The radio is received by the antenna 702. The voice and text information received by the radio is output by the notification means 305, and the earthquake information and disaster information are transmitted to the user more quickly. It is also possible to read out character information as speech.

  Although it is possible to switch to radio reception when the new arrival information is updated in the server 4, the radio reception means 701 operates only when necessary by linking with the earthquake detection information from the gas meter as in this embodiment. Therefore, it can operate and notify only when an earthquake occurs in your area.

  The predetermined radio frequency can be changed from the center server 4. The radio frequency may be AM broadcast, FM broadcast, or TV broadcast.

Serviceability is improved. In addition, it will be possible to provide an information provision service at the time of disaster that is more resistant to earthquake disasters.

  In addition, the present embodiment can provide the same function as the program for causing the communication terminal 2 and the server 4 to function as a computer.

  By using the program, it can be realized as a partial function of a microcomputer, a personal computer, or another device, and convenience and versatility are improved and a system can be easily constructed. In addition, the program can be distributed and installed easily by recording on a recording medium or distributing the program using a communication line.

  In addition, although demonstrated as a gas meter in this Embodiment, not only this but an electric power meter and a water meter may be sufficient.
