| 摘 要： | 在无人值守机站及远程监控的应用中，通常利用Modem进行数据传输。文章分析 了停等式ARQ协议和返回重发式ARQ协议的原理及其传输效率，提出了一种用单片机实现的适 合于无人值守采气站的返回重发式ARQ数据传输协议及其编码方式。采用了类似TCP/IP的流 量控制机制，在实际应用中取得了较好的传输效率。

| Abstract: | In the application of unmanned station and remote monitoring in spar se area, the long distance communication is usually based on modem. By comparin g the mechanism and performance between Stop_and_Wait ARQ and Go_Back_N ARQ(GBN A RQ) protocol, an improved GBN ARQ data communication protocol and frame struc tur e is proposed, which is carried out by single chip system and suitable for u nman ned natural gas gather station. The flow control protocol is similar to TCP /IP. It is proved that the protocol has higher performance by the practical app licati on. |
