综采工作面双齿辊破碎机自动监控装置设计

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

针对现有破碎机监控系统存在监测量有限、控制功能单一、无法联动等问题,开发了一套综采工作面双齿辊破碎机监控系统,重点介绍了该系统中双齿辊破碎机自动监控装置的设计方案。该装置以STM32F103微处理器为控制核心,具有集控、就地、检修3种控制模式,可实现双齿辊破碎机与刮板输送机、转载机等运输设备的联锁启停控制,以及电动机常规保护和状态监测数据显示功能。现场测试结果表明,该装置运行稳定,监测数据准确,能实现双齿辊破碎机与其他运输设备自动联锁启停控制,提高了综采工作面运输设备自动化水平。

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.
