Design and simulation of PLC and HMI-Based control and monitoring system of compressed air application in a pineapple cannery industry

Abstract

Energy Conservation or ENERCON is the main concern of every industry today. With the advent of new technology installed in the process line, the need to address the conservation of applied energy such as steam, water, electricity, and compressed air are still the core to run an industrial plant. The use of compressed air as a blower is widely used now a day for several benefit compared to running the blowing system with the motor. The system presented in this study is used to automatically switch off the compressed air that serves as a can top blower before printing whenever there are no can detected in the conveyors in a pineapple cannery industry. The cutting off of the compressed air used will result in significant saving in the plant-wide drive on conserving energy. The hardware composition, control system design, software application and simulation of the Programmable Logic Controller (PLC) and Human Machine Interface (HMI) - based monitoring and control system of compressed air are present in this work. The system’s main components are PLC, HMI, Inductive sensors and Directional valves. This paper focuses on the application for a pineapple manufacturing plant but not limited to the compressed air application but for all the industrial utilities mention above.
