自动测试系统中实时测控软件的开发

Developing the Measurement and Control Software in Auto--test System

本文通过实例详细介绍了在自动测试系统中采用 Visual Basic(VB)开发实时测控软件的方法:米用MDI窗体技术设计软件的用户界面:采用动态链接库(DLL)实现对硬件接口的控制:采肜事件驱动编程实现测试软件功能的扩展.同时对测控软件中的数字滤波、信号波形显示等技术进行了介绍.

A method of developing the measurement and control software in auto-- test system with VB and DLL is dis-cussed in detail by examples. The user inerface of test software is designed is designed with MDI forms technique. The portof bardware is controled by calling DLL. It is easy to expand the function of test software by the approach of eventdriven pro-gramming. The technique of digital filtering and signal wave displaying in measurement and control software is introduced.
