Multiparameter Fire Detection Based on Wireless Sensor Network
Wireless fire detection nodes based on Wireless sensor network is designed which can detect temperature, humidity and smoke concentration. The ratio of fire misinformation is decreased with multiparameter coincidence technique. And a shortest path routing algorithm is proposed according to multi-hop transmission based on CSIMA/CA principle. The sensor nodes can connect each other automatically and the sensor data can be transmitted within minimum hops, so a real-time fire monitoring system is built up. The result of experiment show: the maximum distance of single hop transmission is 100m; the delay time of every hop within multi-hop communications is about 50ms; the sensitivity of fire smoke reached to I level; the parameter of humidity is used to eliminate the distorted effect of water vapor.
