Design of Data Wireless Acquisition of Fire Alarm System Based on ZigBee and ARM Technology

In order to solve the wiring problem occurred in fire alarm system and signal acquisition of its linkage system,especially to solve the dispersing problem of signal acquisition point in linkage system,a fire alarm data wireless acquisition system is designed which is composed of ARM processors,sensors,ZigBee network and wireless communication technology.Data acquisition and control module acquired the information of fire alarm system,ZigBee data transfer module transferred the data to transmission facilities,the transmission facilities transferred the received data to centralized monitoring center through telephone,Internet or wireless network.Through the test of fire alarm linkage system,this system is accurate,timely and stable.
