Description

  The present invention relates to an information distribution system, for example, an information distribution system applicable to an evacuation route guidance system or a disaster victim location collection system in a facility premises.

  In general, as a means for indicating an evacuation route in a facility premises, a guide map on the premises attached to a wall or a sign posted on a floor, a door, or a ceiling is generally used. Also, in the event of a disaster, in order to communicate the evacuation route and site conditions to users on the facility premises, anomaly detection alarms by various sensors and facility employee reports are once aggregated to the facility manager. In addition, it is transmitted through a local announcement or an electronic bulletin board. Or it is common for employees to guide evacuation.

  When disasters such as earthquakes and typhoons occur, it is important to collect accurate information for quick relief activities and infrastructure restoration activities. In general, when a disaster occurs, a communication system such as a fire fighting radio or a disaster prevention radio is used. Various techniques have been proposed for effective utilization of these systems and for prompt information collection by cooperating with other systems. For example, there is an information transmission system in which a disaster prevention radio system and a mobile phone system are integrated (for example, see Patent Document 1). With this technology, it is possible to effectively transmit emergency information to a person who is in a place where broadcast audio is difficult to reach or a person who is moving by taking advantage of each system.
