摘要
三容液位實(shí)驗(yàn)裝置是進(jìn)行工業(yè)控制實(shí)驗(yàn)和研究的理想平臺，實(shí)驗(yàn)者可設(shè)計出各種控制方案，在實(shí)驗(yàn)裝置上開關(guān)某些手動閥門可以組成相應(yīng)的控制系統(tǒng)，來進(jìn)行實(shí)驗(yàn)和研究。而在計算機(jī)技術(shù)和網(wǎng)絡(luò)技術(shù)高速發(fā)展的今天，利用現(xiàn)有的實(shí)驗(yàn)室裝置和網(wǎng)絡(luò)傳輸技術(shù)來構(gòu)建網(wǎng)絡(luò)實(shí)驗(yàn)室，使實(shí)驗(yàn)室真正具有開放性，可面對更廣泛的實(shí)驗(yàn)和研究。
本文介紹了利用虛擬儀器軟件和網(wǎng)絡(luò)發(fā)布技術(shù)開發(fā)一個三容液位遠(yuǎn)程測控系統(tǒng)。系統(tǒng)設(shè)計是以軟件LabVIEW開發(fā)為主，A3000高級過程控制系統(tǒng)為實(shí)驗(yàn)驗(yàn)證裝備，通過ADAM4000模塊進(jìn)行實(shí)驗(yàn)裝置與系統(tǒng)程序的數(shù)據(jù)通信。最后利用LabVIEW本身自帶的Web發(fā)布功能進(jìn)行遠(yuǎn)程發(fā)布，最終實(shí)現(xiàn)可在Web瀏覽器上對三容液位系統(tǒng)的遠(yuǎn)程測控。本文將涉及有PID控制算法原理、ADAM4000模塊的應(yīng)用調(diào)試方法、LabVIEW7.1的實(shí)用開發(fā)應(yīng)用技術(shù)和LabVIEW程序的Web發(fā)布技術(shù)等。
通過實(shí)驗(yàn)結(jié)果可以說明LabVIEW是一種虛擬儀器軟件開發(fā)中實(shí)用而且操作簡單的工具。隨著LabVIEW這類虛擬儀器開發(fā)軟件的廣泛應(yīng)用，工業(yè)測控的方式將發(fā)生革命性的變化。這種變化將是未來工業(yè)生產(chǎn)控制的發(fā)展的趨勢。

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.
