基于Windows95平台的实时控制技术

本针对微细电火花加工控制这样一个实时性要求很高的计算机控制系统，分析了控制对象对控制软件的要求，对Ｗｉｎｄｏｗｓ９５的系统在实时笥方面有关内容进行深入剖析，指出仅仅通过Ｗｉｎｄｏｗｓ９５的ＡＰＩ，及定时器要完成高精度实时控制是不可能的，并且提出了解决的方法：通过成熟软件ＶｔｏｏｌｓＤ来编写虚拟设备程序。本分析了虚拟设备程序的强大功能，简要介绍了用ＶｔｏｏｌｓＤ编写中断处理程序的方法，介绍了采用

The Real-time Control Technology in Windows95 Environment

The Micro-EDM control system requires the control software can execute the servo function every 1ms.However,it's very difficult to accomplish in Windows95 environment for itself shortcoming.This paper analysis the Windows95 environment and find that the Windows95 is not a virtual 32 bite real-time multitask environment.In this paper a method is proposed:programming VxD with VtoolsD software.With this method,the Micro-EDM system can run stably and correctly for a long time.VxD and the method to use VtoolsD are also introduced briefly in this paper.
