Design and Research of PLC Centralized Control System for Downhole Belt Conveyor in Coal Mines
To improve the automation level of coal mine underground transportation systems and ensure the safety and efficiency of operations.Taking PLC technology as the core,this paper elaborates on the basic composition and various functions of PLC centralized control system,analyzes the main ideas of hardware design,and focuses on the design points of peripheral hardware circuits,PLC software,temperature monitoring,and control subroutines,adapting to contemporary underground operating conditions.A design scheme for a belt conveyor centralized control system with PLC as the core control device is proposed.The experimental results show that the centralized control system manufactured by applying the design concept can effectively play the role of multiple belt conveyor chain control,protection test alarm,fault monitoring,and centralized control of the dispatch center,further optimizing the operating efficiency of relevant units,and has the advantages of automatic control and low-carbon environmental protection.
