Abstract
The design on the use of programmable logic controller, how to control the conveyor belt process, the conveyor belt to reduce electricity consumption in the work to achieve energy-saving purpose .The entire conveyor belt is divided into three sections, each conveyor belt front-end or back-end are equipped with pressure-pressure sensors, used to detect objects on the conveyor belt of whether or location. Programmable Logic Controller (PLC) as the main control circuit, receiving the signal from the sensor output, the preparation of the corresponding PLC software program, you can control the conveyor belt process, and the conveyor control. Using PLC, together with the corresponding external hardware and software program, you can reach the conveyor belt energy-saving requirements.
