Internet Based Data Logging and Supervisory Control of Boiler Drum Level Using LabVIEW

摘要

This paper explains the concept of data acquisition, data logging and supervisory control of a boiler plant which are the basic building blocks of plant automation. The case study of plant having 3 element boiler drum level control system is described. The multiple process variables of this boiler need to be acquired from the field and monitored. The data of the process variables need to be logged in a database for further analysis and supervisory control. A LabVIEW based data logging and supervisory control program simulates the process and the generated data are logged in to the database as text file with proper indication about the status of the process variable. Internet based system can be accessed anywhere without any restriction of place and time.
