  Next, the operation and action in this embodiment will be described with reference to FIG.

  In FIG. 6, the earthquake detection means 307 of the gas meter 1 detects an earthquake, the earthquake detection means 310 of the earthquake sensor 8 detects an earthquake, the logical product determination means 302 determines the earthquake detection, and the seismic intensity information of the earthquake is obtained. It is a flowchart which shows the operation | movement which acquires required information according to it. The explanation will be made with reference to FIG. 3 as appropriate.

  When an earthquake occurs, the earthquake detection means 307 of the gas meter 1 detects a shake and notifies the meter control means 309 of the shake level as meter earthquake detection information (S601).

  Further, the gas meter 1 has a function of shutting off the gas when the seismic intensity is equal to or higher than a predetermined seismic intensity. If the seismic detecting means 307 indicates a predetermined seismic intensity, the meter control means 309 controls the valve shutting means 308. 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 due to the earthquake occurs, a telegram for notifying the occurrence of an abnormality is generated by the meter control means 309 and transmitted to the wireless device 1d and transmitted to the wireless communication means 301 of the communication terminal 2 via wireless communication. (S602).

  At the same time, the earthquake is detected by the earthquake detection means 310 of the earthquake sensor 8 (S603).

  Further, the level of shaking is transmitted as the earthquake sensor earthquake detection information to the wireless communication means 301 of the communication terminal 2 via the wireless device 8d (S604).

  Two pieces of earthquake detection information, meter earthquake detection information and earthquake sensor earthquake detection information, are input to the logical product determination unit 302 via the wireless communication unit 301. At this time, the logical product determination unit 302 calculates the logical product of the two earthquake detection inputs, and determines that there is an earthquake detection if there is two pieces of earthquake detection information (S605).

  As the seismic intensity information included in the earthquake detection information, the larger one of the two earthquake detection information is acquired and used as seismic intensity information for the earthquake detection. Alternatively, an average may be taken, and the one with higher reliability of earthquake detection information may be used with priority. For example, use the value of the gas meter (the number of false detections is less because the installation standards are strict), store the earthquake detection means installation time, maintenance time, and version information of the detection program. It is also possible to use.

On the other hand, when only one of the gas meter seismic intensity information (S601) and the seismic sensor seismic intensity information (S603) is input, it is not determined as an earthquake detection. If the two earthquake detection inputs are not available, it is assumed that there will be impacts on meters, earthquake sensors, etc. due to civil engineering work, etc., preventing false detection of earthquakes.

  When the logical product determination unit 302 determines earthquake detection, the logical product determination unit 302 notifies the earthquake information acquisition unit 303 to acquire earthquake information.

  The earthquake information acquisition unit 303 generates a telegram for an earthquake information acquisition request, controls the outside communication unit 304, and transmits the telegram to the server 4 through the Internet 3. The server 4 analyzes the contents of the message, and if the contents are an earthquake information acquisition request, the information recorded in the earthquake information database 505 is set in a response message and is received by the communication terminal 2 (S606). At this time, the server 4 responds with necessary information according to the seismic intensity information set in the telegram of the earthquake information acquisition request.

  The information includes emergency information (such as tsunami information) that should be urgently communicated to each user, evacuation instructions / recommendations issued by the government / local government, damage status, lifeline (gas, electricity, water) status, recovery prospects, road, This includes traffic information such as the status of transportation, recovery prospects, life support information on disaster books, and information on consultation desks provided by local governments.

  Depending on the seismic intensity information, for example, if the seismic intensity is 5 or higher, the communication terminal 2 will sound an alarm sound and give priority information and notification of emergency information such as tsunami information and evacuation advisories. For example, without sounding the notification sound, it provides information centered on information such as the situation of damage, roads, transportation, lifelines (gas, electricity, water) in various places that are highly relevant to daily life. In this way, necessary earthquake information is changed and provided according to seismic intensity information.

  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 (S607). 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 to the user's mobile phone 5 using this system by e-mail in a timely manner.

  The earthquake detection information that is detected and notified by the gas meter 1 or the earthquake sensor 8 includes seismic intensity information and is set in advance to a predetermined value.

  At this time, the priority of the earthquake information acquisition to the server 4 of the out-of-home communication means 304 according to the seismic intensity information (shake level information) (for example, a plurality of waiting times are provided depending on the seismic intensity information (shake level information)). In addition, the earthquake information may be acquired with the gas cutoff abnormality information due to the earthquake 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.

  In the present embodiment, it has been described that when the seismic intensity information of two inputs is different, the larger one is acquired. However, the present invention is not limited to this.

  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.

  Moreover, although the specific low power radio | wireless was demonstrated as a communication means of the communication terminal 2 and the gas meter 1, power line communication, Ethernet (trademark), wireless LAN, etc. may be sufficient.

  Moreover, although the case where there were two seismic detectors including a seismic instrument of a meter was demonstrated, three or more may be sufficient.

  The specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  As described above, the earthquake detection unit 307 of the gas meter 1 detects an earthquake, the valve blocking unit 308 blocks the gas, the earthquake detection or the gas blocking information by the earthquake detection is transmitted to the communication terminal 2, and When an earthquake is detected by the earthquake detection means 310 of the earthquake sensor 8 and transmitted to the communication terminal 2, and when two earthquakes are detected by the logical product determination means 302 to which the earthquake detection from the two earthquake detection means is input By using earthquake detection means of existing meters widely spread to ordinary households by judging earthquake detection, and determining the earthquake detection information of multiple earthquake detection means including earthquake detection information of the meter by logical product Makes use of highly reliable gas meter earthquake detection means that will continue to operate without maintenance for 10 years, and the earthquake detection information of the meter Judgment of earthquake detection information of multiple earthquake detection means, including logical earthquakes, provides highly reliable earthquake detection and is necessary for users who deal with earthquakes that occurred via a wide-area communication network and is timely. Earthquake information can be provided.

(Embodiment 2)
A second embodiment of the present invention will be described below with reference to FIGS.

  FIG. 7 is a block configuration diagram of the communication terminal 2 according to the second embodiment. FIG. 8 is a flowchart showing an operation of detecting an earthquake by the logical product judging means 302 of the present embodiment and controlling a predetermined device when the earthquake is detected. The present embodiment is different in that earthquake information is acquired when an earthquake is detected, and the device is controlled via the wireless communication unit 301 according to the seismic intensity information. The same components as those in the first embodiment (FIGS. 3 and 6) are denoted by the same reference numerals, and description thereof is omitted.

  In FIG. 8, when the logical product determination unit 302 determines earthquake detection (S605), the device control unit 306 is notified of earthquake detection information. As in the above embodiment, the earthquake information is acquired from the server according to the seismic intensity information of the earthquake detection information, notified by the notification means 305, and the earthquake information is provided to the user. In addition, the seismic intensity information (swing level information) included in the earthquake detection information is determined. If the seismic intensity is equal to or higher than a certain level, for example, if the seismic intensity is 5 or higher, a device connected in the device control means 306 (in this embodiment) A predetermined control signal is transmitted from the wireless communication means 301 to the electronic lock 701 and the breaker 703 (FIG. 7) (S801).

  An unlocking control signal is transmitted to the electronic lock 701, and a breaker OFF control signal is transmitted to the breaker 703, which are received by the wireless devices 702 and 704, respectively. The interlocking control is performed as described above (S802).

  Note that although the electronic lock 701 and the breaker 703 are described in this embodiment mode, there are no restrictions on the devices to be linked, and any home appliances or facility devices that can be controlled by wireless communication may be used.

  For example, when a combustion device such as a gas table, a gas fan heater, or a gas water heater is operating, the stop control may be similarly performed wirelessly. In addition, it may be controlled to open an electric shutter or the like instead of an electronic lock to secure an escape path. It is also possible to turn on the lighting at night and turn on the TV to display earthquake information to prevent residents from panicking.

  As explained above, in addition to acquiring earthquake information according to seismic intensity information of highly reliable earthquake detection, if the seismic intensity is above a certain level, the device connected to the communication terminal 2 can be linked and controlled As a result, the primary response in the event of an earthquake can be performed more quickly, the safety of users in the event of an earthquake can be improved, and the serviceability of the system can be improved.

  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. Also, 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.

  Further, one of the earthquake detection means 310 may be provided on the communication terminal side.

  As described above, the communication terminal, the earthquake handling method, and the program according to the present invention are realized by connecting the device provided with the earthquake detection means and the communication terminal, and therefore can be similarly realized if the device is provided with the earthquake detection means. It is. For example, it can be applied to energy systems such as fuel cell systems and cogeneration systems.
