Design of automatic monitoring and control device for double-gear roller crusher in fully mechanized working face

Abstract

For problems of limited monitoring parameters, single control function and inability to linkage in existing crusher monitoring and control systems, a double-gear roller crusher monitoring and control system in fully mechanized working face was developed, and a design scheme of automatic monitoring and control device for double-gear roller crusher in the system was emphatically introduced. The device, which adopts STM32F103 microprocessor as control core, has three control modes namely centralized control, on-site control and overhaul, and can realize functions of interlocked start-stop control among conveyers of double-gear roller crusher, scraper conveyor, stage loader and so on, normal protections of motor and status monitoring data display. The field test result shows that the device has stable operation and accurate monitoring data, and can realize automatic interlocked start-stop control among double-gear roller crusher and other conveyors, which improves automation level of conveyors in fully mechanized working face.
