摘 要:多路双工无线呼叫系统利用LM567进行编译码,利用单片机实现多路选择,进行调频后发射,CXA1191对信号进行接收,从而实现多路双工无线呼叫。该系统工作稳定,利用不同的发射频率可实现频分复用,可应用于小区管理。同时,略加改造可实现短信传送、广播等功能。In the multi-route division-dual wireless calling system,LM567 is applied to code encoding and decoding while Single Chip Micyoco(SCM) is adopted to realize multi-route selection and code frequency modulation and transmitting.Meanwhile,CXA1191 receives the signals and the multi-route division-dual wireless calling is achieved.Such system is stable and applicable in residential quarters and different transmitting frequencies can be reused through frequency division.Moreover,slightly improved,it can be endowed with functions such as message delivery,broadcasting and so on.
