Making use of programming characteristic and rich inner resource of CPLD(Complex Programmable Logic Device),a wireless alarm sending system was designed,which include address encoding circuit,FSK modulate signal and each channel controller signals to decrease volume and increase reliability of the system.
无线报警系统的发射装置,利用CPLD(复杂可编程逻辑器件)的可编程特性、丰富的内部资源,设计了包括地址编码电路、FSK调制信号及各路控制信号在内的数字系统,减小了体积,提高了系统的可靠性。
In the paper the principle and the configuration of the wireless alarming system is introduced, meanwhile the anti-interference measurement and the way to low the error-alarming rate are mentioned .
对每一防区设置不同的地址编码 ,当防区出现警情后发射机发出无线报警信号 ,接收机对设防区的地址编码进行自动识别 ,同时显示出该区的编号并发出警报 。
