An ultimatum requirement is an accurate and precise data acquisition mechanism which can be executed through diverse sensors especially for collecting, analyzing and sorting the objects and elements. In this work, an energy efficient conveyor system model is proposed and implemented which not only recognizes and sorts the objects by sensing its colour and place these objects to its destination by using Robotic vehicle but also smartly adjusts the speed of conveyor belts by recognizing the weight of object(s). The variable speed drive (VSD) based an optimal belt speed control mechanism is proposed by smartly sensing the object weight and optimally adjusting the belt speed. The proposed system optimally switches the conveyor system to on/idle/off status to minimize the energy consumption of conveyor belts. In this work, a mathematical model of the energy efficient conveyor system is also derived by considering the different dynamic parameters. When conveyor belt is fully loaded with objects, the belt moves around with its maximum potential speed, but when conveyor belt is partially or marginally loaded or unloaded, the speed of belt is adjusted accordingly. In this way, a significant amount of energy and cost of energy can be saved. It is anticipated that, the developed intelligent energy efficient conveyor system model will not only modernize the industrial manufacturing and distribution process but will significantly reduce the energy consumption and cost and will lead to increase the life time cycle of conveyor belts.

Introduction In any industrial processing plant, the ultimatum objective is to produce standard and high quality products and sell them at prices which make profits. These objectives can be achieved by efficiently designed and optimally controlled processing plants. A process is set of equipment and materials specifically related to some manufacturing operations or system mechanism. The process control is the system of gathering the system information, quantifying the state of the process, standardizing the rules and guidelines to actuate the control elements accordingly [1]. For any process control system, such actions can be executed manually where only humans are involved or in a semi-automatic way where both machines and humans both are mutually involved or even without any
