Description

  The present invention relates to a system connected to a wide area communication network for communication, and more particularly to an emergency earthquake warning system for broadcasting an emergency earthquake warning.

  In recent years, with the development of communication infrastructure, various additional services related to communication have become widespread. For example, telephone devices that can connect to a wide-area communication network such as an IP telephone network or the Internet and receive various services such as a data communication service have become widespread.

  As one of the functions provided in such a communication device, there is a function for receiving an emergency earthquake bulletin distributed by the Japan Meteorological Agency when an earthquake occurs. Earthquake early warning is an information distribution service that will be implemented from October 1, 2007 AD. The user can use this service by purchasing a communication device corresponding to the earthquake early warning and making a contract with a distribution service company for the earthquake early warning.

  A communication device that has received an earthquake early warning when an earthquake occurs uses local information recorded in advance in the communication device, for example, latitude / longitude information of the location where the communication device is installed, etc. Of earthquake motion, the part most felt by the human body (usually the S wave) is calculated.

  The calculation result is notified to the user, for example, by displaying an image on a liquid crystal panel or outputting sound through a speaker. Thus, the user can take an evacuation action such as hiding under the desk or extinguishing the source of the fire before the main motion arrives from the epicenter.

  Patent Document 1 discloses an image processing apparatus that can suppress the possibility of a secondary disaster such as a fire due to an earthquake as compared with the conventional apparatus as an apparatus capable of receiving the emergency earthquake warning as described above. The image processing apparatus includes a communication control unit that performs communication with an external device, and a power source control unit that changes an energization state inside the apparatus.

  Then, when the communication control means receives the earthquake early warning from the external device, the power supply control means is controlled to change the energization state. By controlling the power supply based on external information in this way, it is possible to prevent erroneous detection of earthquakes due to vibrations other than earthquakes, such as when working nearby or accidentally colliding with equipment, without compromising convenience. Safety can be ensured.

  In relation to the above, Patent Document 2 discloses a portable early earthquake warning device capable of collecting early earthquake information and determining whether or not it is necessary to call attention before reaching the main motion of the earthquake motion. . This portable early earthquake warning device has a position information receiving means, an emergency earthquake warning receiving means, a position information received by both receiving means, and an earthquake early warning, before the arrival of the main motion of the earthquake motion. Is provided with means for determining whether or not attention is required.

According to this, since warnings can be issued before the main motion of the earthquake motion reaches the railroad vehicles and automobiles, it is possible to take measures to stop the railroad vehicles and automobiles quickly, and the occurrence of great damage. Can be prevented.
