Design of Residual Coal Cleaning System for Train Wagons Based on PLC

In this paper, a set of PLC-based train wagons residual coal cleaning system is proposed for the time-consuming, laborious, inefficient and other problems of manual cleaning of residual coal in coal train wagons. The system includes two components: mechanical system and control system. Among them, the mechanical system includes two parts: the crane and the cleaning device; the control system consists of hardware and software parts. In this paper, we first determine the control program of the train wagons residual coal cleaning system, and select the main components in the system. After clarifying the control mode of the whole system, it completes the writing of the control program and the development of the host computer software. Finally, after the system test, the residual coal cleaning system can automatically identify the wagon number and locate the position of the wagon, and clean up the residual coal with high efficiency and intelligence. In the test process, the system only needs 3 minutes and 30 seconds to complete the efficient cleaning of the residual coal in the wagon, and the test results show that the whole set of system cleaning effect is good.
