摘　　要：根据电缆无线测试仪的功能需求,以操作简单、方便为目的,采用无线串行通信模块PC-903和UTC903,构建无线通信模型,实现上下位机间无线串行通信。在上位机中运用C#串行类的事件触发机制,实现串行通信,利用多线程技术提高系统实时性;针对下位机,介绍了UTC903与单片机的连接关系,利用中断方式实现无线通信程序的过程。经工程实践证明,数据传输可靠,距离远,具有良好的工程应用价值。According to the functional requirements of the cable wireless tester. A wireless serial communication between the upper and lower machine is achieved through using wireless serial communication module PC-903 and UTC903 and building wireless communication model for the purpose of simple and convenient operation. In the host computer, realize the serial communication by using the event trigger mechanism of C# serial class, and improve the system real-time through multi-threading technology. Introduce the connection relationship of the UTC903 and the microcontroller, achieve the wireless communication program process with the interrupt. Engineering application prove that data transmission is reliable and distance and has a good value in engineering.
