Wireless fire detector for early fire recognition

The invention relates to a fire alarm, in particular to an early fire recognition detector based on the combination of a sensor array technique and a ZigBee wireless technique. The detector is achieved by a sensor array module, a mode recognition module and the ZigBee wireless technique, wherein the sensor array module consists of a plurality of paths of gas sensors and temperature sensors; and after the processing by a signal processing module, a fire recognition algorithm is adopted to detect and recognize the gas generated at an early stage of fire; a ZigBee sends the result of the recognition, the temperature and the smoke intensity to a monitoring center in a wireless mode; and a computer of the monitoring center achieves the positioning of a fire source point and the description of a three-dimensional space of a temperature field and a smoke field. The detector has the advantages of the early fire recognition, the positioning of the fire source point, and visual descriptions of the ...
