计算机调速控制系统I/O通道故障检测

I/O Tuouble Measure Passway Device of Computer Adjust and Control System

本文在分析计算机调速控制系统的基本组成和工作原理的基础上,从基本数据流程控制入手,按功能作用分别对系统的输入输出控制信号进行了归类和分析。用89C51型8位单片机代替32位单片机,设计并开发了该控制系统的L/O通道故障检测装置。为现场技术人员提供了快速、准确的故障检测和维修方法,保证了设备的可靠运行,提高了生产效率。

This paper theoretically analyses the basic components and work principles of the computer speed control system. Beginning with the basic data flow control, we categorize and analyses the input and output control signals by functions, replace the 32-bit singlechip with 89c51 8-bit singlechip, design and develop the failure detection device for the control system I/O channels. We provide the fast, accurate means for the technicians on site to detect system failure and maintain the equipments, which ensures the reliable operation of the equipments and enhance the work efficiency. The practices prove it works well.
