The structure of intelligent automatic fire alarm system based on LabVIEW virtual instrument

In order to reduce the false and leakage alarm rate of automatic fire alarm system,a set of intelligent automatic fire alarm andanalysis control system was developed based on LabVIEW virtual instrument.In this paper,the function and realization method of hardware and software was mainly introduced.The hardware part which adopted the self-created two bus protocol and ZigBee wireless technology improved the reliability of signal transmission.The software part which added fire voice alarm functions,data files auto-save functions and BP neural network algorithm improved the system intelligent level.The experimental results show that,the system can effectively realize the monitoring regional temperature smoking collection,analysis and calculation,alarm accurately.The design of software with the advantage of friendly interface,complete functions has a broad application prospect.
