Design and implementation of internet-based remote monitoring for continuous vacuum pans in sugar factory

Abstract

This paper presents a practical technique to design and implement the Inter- net-based system for remotely monitoring key performance indicators (KPIs) in operation of vacuum pans for sugar crystallization by using supervisory control and data acquisi- tion (SCADA) software, which provides web-enabled human machine interface (HMI). The remote monitoring system for the DECHAROEN™ continuous vacuum pans is de- scribed as an illustrative case study to verify the proposed technique performance. At the remote site, the programs (or script functions) based on web services were developed for detecting and collecting the KPIs in the text file format from the operator workstation of the host system in the raw sugar plant. The created text files are transferred to the data center through the Internet. At the data center, the database was created using XAMPP software, and the website and web pages were built using HTML and CSS. The proposed system can be useful in performance analysis for continuous quality improvement. Experimental results demonstrating the proposed monitoring system are also included.
