| 摘 要： | 介绍了集中式绝缘在线监测系统中上下位机间的端口通信(包括计算机与多路选通开关间的并口通信及与数字波形采集装置间的串口通信)的基本原理、设计方法及程序实现。并口通信在VC中用一个函数语句即可实现,编程简单、运行稳定可靠;串口通信实质上是上位机和单片机AT89C51间的通信,单片机用查询发送、中断接收 的通信方式,上位机通信用Win32API函数开发,在动态链接库中实现,可很好地满足系统的实时性要求。

| Abstract: | The port communication technology applied in t he centralized on-line insulation monitoring system is consists of two types. O ne is the parallel port communication to connect computer to the multiplexer cha nnel switch. The other is the serial port communication to communicate between c omputer and the data sampling device. The parallel communication is easy to real ize by using a single function in VC. The serial port communication is essential ly the communication between PC and the single chip computer AT89C51. The AT89C5 1 communicates by querying sending and interrupting receiving mode, the PC commu nicates by developing of Win32API function and realization in DLL. The communica tion can satisfy the requirement of real time well. |
