Research Of Intelligent Fire Alarm System Based On Fuzzy Neural Network

Coupled with the rapid development of large space and higher and comprehensive building, the loss and effect caused by fire are becoming bigger and bigger. Due to the increasing complexity and uncertainty of the fire detection sign and the drawback of traditional fire detection alarm system, the phenomenon of wrong alarm and miss alarm are very popular and attract people's attention.Coupled with the rapid development of intelligent and network techniques, technology platform and supports are provided for solving the wrong alarm and miss alarm. The rich resources for fire detection are available because of intelligent buildings and communities are brought forward. Therefore intelligent level of fire detection gradually became the topic of people's research.According to the characters of fire detection and complex objects of fire detection, the properties of various fire detection system and the reasons of wrong alarm are analyzed. Conclusion is that the key to detect fire accuracy is to enhance the intelligent level of fire detection. Therefore the application of fuzzy neutral network in dealing with information of fire detection and the design of hardware system are mainly studied.The network parameters are exercised by forward BP network, and then whether fire or not are determined by fuzzy logic. Finally, the experiments related to standard test fire indicated that this network can not only detected various standard test fire accuracy, but also have good anti-interference capability.A intelligent fire alarm system which has property of wireless transmission is developed based on the multi-data amalgamation techniques and wireless-LAN techniques, the detection characters are improved with the use of series measurements ,such as fuzzy neutral network, anti-interference designation, communication of wireless transmission, multi-sensor integrating smoke sensor and temperature sensor and co sensor, combination of warn and alarm. The intelligent fire alarm system which is simple and powerful function satisfied people's demands, Comparing with similar products on the stage, it has a highly cost-effective,and therefore it has complete amplitude market space.
