Auto Quality Testing and Filling Station by using NI LabVIEW and Specially Designed OFS

Abstract

Quality testing for various parameters of the final product of the miniature plant is performed by using various sensors. The sensors include LDR, PH meter, Thermo couple, Optical fiber sensor (OFS). pH, level, temperature, weight and turbidity are few parameters that are tested in this miniature industrial prototype. Miniature model of a bottle filling plant has been designed to implement various sensors and actuators. OFS is an optical sensor that converts weight into electrical signal. It is based on the micro bending phenomenon. All the sensor signals are taken and actuator signals are given by the LabVIEW Data Acquisition through Compact Field Point. The
automation, data logging and process controlling has been achieved by a Virtual Instrument (VI) designed on National Instrument’s LabVIEW platform. Motivation for the project: Any automated industrial plant or process needs to be monitored by sensors and controlled by a controller. The controllers to handle such sophisticated industrial processes need to be inevitably flexible and easier to program. Modular control is also a desirable tradeoff. All these requirements are satisfied by the graphical programming of LabVIEW VI.Iterative uniformity being the most important factor of output of any process, quality of the end  products is tested for uniformity of various parameters. This quality testing helps in giving the system a feedback and a control input. The tested values are monitored by data logging in the form of graphs and charts.
