Design of Belt Conveyor Deviation and Tearing Condition Monitoring System Based on PLC Monitoring System
[Purposes]This paper aims to design a real-time monitoring system for the most serious issues affecting safety production in the comprehensive working conditions of belt conveyors,such as deviation,tearing,and emergency stop locking.This system can perceive the survival status of conveyor belts in real time and automatically warn of abnormalities,and it provides a basis for operation and handling for relevant personnel on the conveyor belt,and improves the start-up rate of belt conveyors.[Methods]Firstly,the formation mechanism and characteristics of common faults such as belt conveyor deviation,tearing,and emergency stop locking were analyzed,and the corresponding monitoring parameter require-ments for working conditions were clarified.Then,based on the actual harsh level of working environ-ment in the mine production process,as well as the degree of demand for working condition monitoring and fault emergency protection,suitable monitoring sensors were selected.Finally,combining with PLC control,an implementable system scheme is formed.[Findings]Through comparative evaluation of schemes,a PLC based monitoring system for belt conveyor deviation,tearing,and emergency stop lock-ing conditions was ultimately constructed.[Conclusions]This article establishes the principle of select-ing monitoring sensors and forms a specific monitoring and control design method for belt conveyors,pro-viding engineering guidance for improving the operational reliability of coal mine belt conveyors.
