Control Of Process Variables For Remote Applications Using Lab VIEW And Internet

Abstract

The paper presents a system that monitors and controls process variables for remote applications. LabVIEW (short for Laboratory Virtual Instrumentation Engineering Workbench) is a visual programming language commonly used for Data Acquisition (DAQ) and control. LabVIEW contains a user interface, known as front panel objects. By this we can access the acquired process variables over the internet. The accessed process variables like temperature, pressure, strain or any other can be suitably conditioned and feedback for control of the process via the internet for control. The system would find wide application in processes which are hazardous in nature. People can be safeguarded from hazardous effect, in dangerous areas like chlorine industry or at places where person gets affected by dangerous gases. This note presents one such idea using LabVIEW and Internet.
