摘要
介绍一种以８０３１单片机为核心的开关（状态）量监控装置。它由主板、开关量采集板、控制板及显示／键盘板等组成。可用于２５６点开关量的采集、监视和８个开关量的合、分操作。具有功能强、适用面广等优点。已在某电厂防误操作监视专家系统中采用。
The paper discusses about a new equipment called switch-status surveillance and control system.The system is made up of a main panel,a switch-status collector, a control board and display/keyboard circuits.A 8031 sigle chip microcomputer is the core of the system.The system is able to survey 256 switches by means of collecting the status of each switch.And it is able to handle 8 switches at the same time.This system is effective in function,so it can be used in many fields.At present.the system has been used as a subsystem of the expert system which is applied in a power plant to prevent misoperation.
