摘要
利用试验室微机系统现有的A/D采集卡和计算机来构成多路逻辑控制电路。通过开发控制软件来控制其开关量的状态,产生逻辑控制,其作用等同于一个有12路开关输出量的可编程逻辑器。这样极大地精简了电器控制线路,使故障易于排查。
A multiple channel logic control circuit ry microcomputer system and computers. Control is constructed by the A/D capture card of laborato- software is developed to control its switch quantity condition and produce logic control. Its role is the same as that of a programmable logic controller with 12 channel switch output. It greatly reduces electric appliance control wiring and is convenient to investigate the breakdown.
