摘　　要：在很多场合有线通信技术并不能满足实际需要,比如在野外恶劣环境中作业。使用无线射频通信芯片构建的通信模块,用单片机作为控制部件,配合一定的外围电路就能很好地进行两地空间区域信号对接,实现自由数据通信,解决了无线通信的技术难题。并且其具有硬件构造简单、维护方便、通信速率高、性能稳定等优点,能在电子通信业得到广泛应用。In many occasions, wired communication technologies can not meet the actual needs. The data transmission of spacial signals between two regions and free data communications can be achieved by the communication module based by RF communication chip which takes MCU as a control component and matches with some peripheral circuits. This is a good way to solve the difficulties that the wireless communication meets with. It has the advantages of simple hardware structure, easy maintenance, high communication rate, stable performance, etc. It can be widely used in the electronic communications industry.
