摘　　要：本文详细介绍了在工业现场强电磁干扰的环境中，基于ＷＩＮＤＯＷＳ　ＴＭ９８操作系统的工控机与 ＭＣＳ－５１单片机间串行口传输大批量数据的编程技术。文中着重分析了实际通信中可能出现的传输错误以及通信线程Ｔｉｍｅｏｕｔｓ设定等问题，同时给出了相应的解决方案。In this paper, programming techniques are introduced in details, which are for transfer of large quantity of data via serial port between MCS-51 and industrial controlling computer based on WINDOWS TM 98 system in the industrial field with strong electromag- netic interference. And authors pay attention to transfer mistakes and settings for timeouts item in communication thread, then put forward corresponding solutions.
