摘要
潍坊华泰电子仪器有限公司生产的DO30-Ⅲ交直流标准源具有很高的市场占有率,本文论述了微机与DO30-Ⅲ交直流标准源配套使用时微机上数据采集与控制软件的设计方案与主要技术,以及微机与标准源的硬件连接技术。微机与标准源间采用RS-232C串行口进行连接,微机一侧采用VB进行软件开发,使用MSComm控件实现对串行口的访问,文中详细讨论了访问控制的原理并给出了关键技术代码。
The DO30-Ⅲ DC/AC voltage and current standard supply produced by WeiFang HuaTai electric instrument co. ,ltd has the very high market share.This paper analyzes and discusses the design proposal and main technology of data sampling and control system software as well as microcomputer and standard supply hardware connection technology when DO30-Ⅲ DC/AC voltage and current standard supply is applied with microcomputer. Microcomputer connects standard supply through RS-232C serial port. The microcomputer software designed by VB programming language and uses mscomm control to accesses the serial port.The paper discussed the access principle in detail ,and presents major codes of key technologies.
