微机测控系统在行走式节水灌溉试验台车上的应用

摘要

This paper puts forward a design of microcomputer measurement and control system in test trolley, mainly introduces the design of hardware including sensors, amplifiers and data acquisition cards and the design of measurement and control system software which could get the external data and control solenoid on- off valve, motor＇s start- stop and posi- nega rotation with the Visual Basic program to control multifunction data acquisition card.%设计试验台车上的微机检测与控制系统。主要介绍硬件设计，包括传感器和放大器、数据采集卡等；介绍测控系统软件的设计，采用Visual Basic程序控制多功能数据采集卡来获取外界数据、控制电磁阀开和关、电机的起停及正反转。
