摘要
三容液位实验装置是进行工业控制实验和研究的理想平台，实验者可设计出各种控制方案，在实验装置上开关某些手动阀门可以组成相应的控制系统，来进行实验和研究。而在计算机技术和网络技术高速发展的今天，利用现有的实验室装置和网络传输技术来构建网络实验室，使实验室真正具有开放性，可面对更广泛的实验和研究。
本文介绍了利用虚拟仪器软件和网络发布技术开发一个三容液位远程测控系统。系统设计是以软件LabVIEW开发为主，A3000高级过程控制系统为实验验证装备，通过ADAM4000模块进行实验装置与系统程序的数据通信。最后利用LabVIEW本身自带的Web发布功能进行远程发布，最终实现可在Web浏览器上对三容液位系统的远程测控。本文将涉及有PID控制算法原理、ADAM4000模块的应用调试方法、LabVIEW7.1的实用开发应用技术和LabVIEW程序的Web发布技术等。
通过实验结果可以说明LabVIEW是一种虚拟仪器软件开发中实用而且操作简单的工具。随着LabVIEW这类虚拟仪器开发软件的广泛应用，工业测控的方式将发生革命性的变化。这种变化将是未来工业生产控制的发展的趋势。

The exoerimental apparatus of There-tank Level is a perfect platform which proceed experiment and research of industrial control.By the platform,the experimenter can design different kinds of arranegement of comtrols, then by tapping certain manual vavle in devices compose the parallelism control systems for experiment and researching.Whereas at the age of computer and network technique’s high speed development, the network laboratory which compose with available device and network transmission technology would be more openness,and approve more comprehensive experiment and research.
The paper introduced  how to develop the There-tank Level Remote Mearsuring and Control System by utilizing virtual instrument software and network release technology. The system was developed by the software of LabVIEW ,taken to experiment in platform of A3000 high class process control system, used  the module of ADAM4000 for data communication.Finally we  utilized Web releasing function of LabVIEW for mearsuring and controling the There-tank Level System in the Web browser. In the paper, it related to the PID control algorithm theory, the application debugging method of ADAM4000, the utility adaptive technology of LabVIEW7.1 and the releasing technology of LabVIEW7.1 etc.
The software of LabVIEW is the utility and simplicity of operation tool in the development of virtual instrument. And the mode of industrial measuring and control should be a revolutionary change in company with the extensive used of the software virtual instrument as LabVIEW. The change will be a current of production control in the futurity industry.
