摘要： An evacuation guidance system is configured from multiple sensor modules, network lines, guidance indicators, and a guidance control device. Each sensor module includes multiple input/output port pairs, fire detection sensors, and a data control unit. The multiple input/output port pairs are connected to input/output port pairs of other sensor modules by means of network lines, thereby configuring a mesh-like autonomous network. The data control unit generates and outputs fire data after adding fire location data; upon receiving fire data, outputs the fire data after adding its own route flag; and stops the output of fire data when the fire data contains its own route flag. Upon identifying the location of the fire outbreak from the fire data, the guidance control device calculates optimum evacuation routes and causes the guidance indicators to turn on/off or flash.
