针对现在基于PLC的电磁调速电牵引采煤机控制系统存在的体积较大、功能简单、扩展性差、安装走线繁琐、抗震动性能弱等问题,设计了一种新型的嵌入式电磁调速电牵引采煤机电控系统.此设计将控制系统划分为5个模块,以CAN总线进行连接,以嵌入式STM32F103RCT6作为控制系统的中央处理器,同时部分模块使用了性能优异的单片机控制器.该控制模块结构灵活,扩展性、抗电磁干扰、抗机械振动能力强.通过测试,证明此设计效果良好,具有可行的应用价值.“,”A new type of electrical control system applied in embedded electromagnetic speed-adjusting shear was designed in this paper,to solve the problems of the existing PLC-based control systems,such as large volume,simple function,poor expansibility,complicated wiring,poor anti-vibration performance,and so on.This system consists of five parts,which were connected by CAN Fieldbus,and STM32F103RCT6 was used as its central processing unit.Meanwhile,some modules used single chip with good performance as the controller.This system is not only flexible in structure,but also has good expansibility,strong anti-electromagnetic interference,and high mechanical vibration resistance.The design was proved to be efficient and have practical application value through the tests.
