摘要
本文针对一些相对局限性较大的通信系统,或者是产品成本费用过高以及维修困难等问题,着重设计一种对于短距离方便时应用的接收器——无线呼叫系统接收器。它是一种基于无线通信网络技术的呼叫系统,包括发送和接受两大部分。利用收音模块、音频输出模块、数据接收模块以及控制模块设计无线呼叫系统,完成信号的接收、解调、输出等功能,实现有效接收距离100m左右,能满足在中小型场所的使用需求,具有制作成本低,便携轻盈占地面积小,灵活性和灵敏度高,效率高,抗干扰能力强等优点。
In this paper, a receiver application at a convenient time for a short distance - wireless call system receiver was designed to solve the problem of relative limitation of a larger communication system, or the high cost and maintenance difficulties. The wireless call system bases on wireless communication network technology, including the transmission and acceptance of two parts. Radio module, the audio output module, the data receiver module and control module was designed to realize signal reception, demodulation, and the output function. The effective receiving distance is iOOm, it can meet the needs of small and medium-sized establishments, .with the advantages, such as low cost, high flexibility and sensitivity, strong anti-interference and so on.
