摘　　要：　给出一种用单片机系统进行曼彻斯特编译码,实现多路测井数据传输的技术方案,整个传输系统分为编码系统和解码系统.编码系统将采集到的数据经过编码、驱动后送至遥测电缆,编码信号传至地面后经解码系统恢复成原始数据,并送至微机系统.实测结果证明,编码数据能够经过5000m的电缆传至地面,并由解码系统恢复.同时也证明了用单片机软件实现曼彻斯特编码传输的方案是可行的.This paper presents a technical method of Manchester coding and decoding by single-chip microcomputer with software to implement logging data transmission of multiple channals. The whole transmission system is divided into coding system and decoding system. The coding system delivers the gathered data to telemetry cable after coding and driving. While transmitted to the ground, the coding signals are resumed to initial data by the decoding system and then carried to the computer system. It is proved successfully that data can be transmitted from the coding system to the ground through the cable of length more than 5 000 meters and then resumed by decode system. It shows that this method is feasible.
