基于Winsock的网络实时控制程序开发

Research of Real-time Control Program Based on Winsock in LAN

传统的实时控制实验方式只能实现本地控制操作 ,即一台控制设备只能在对应的控制机上实现 ,不仅限制了实验室的应用范围 ,而且不利于自动管理 .本文以水位控制系统为对象 ,描述了在 delphi环境下使用 Winsock组件并嵌入底层汇编的网络控制程序 .这可以实现在局域网内任何一台 PC机上远程访问控制设备 ,实现实时远程数据采集、控制参数及命令发送、图像传送等远程实验功能 .该软件使得实验室设备资源在局域网内可以真正做到远程共享和自动管理 ,提高了设备利用效率 ,为师生异地实验提供了方便 .

This paper introduced a new remote software based on winsock module in school-LAN. Deviser imbeds assemble language in Delphi program so that it can realize sampling and control for the hardware equipment. Any computer in the LAN can log on the control-server to implement data sampling, parameter sending out, image and curve display etc. The software realizes resource share, automatic managing and greatly offers convenience of remote experiment for the students.
