摘　　要：简要介绍了ARM(Advanced RISC Machines)微控制器和CAN(Controller Area Network)总线技术构成的煤矸石在线识别与自动分选系统,给出了ARM微控制器AT91M40800与CAN总线控制器SJA1000之间相连的硬件电路,论述了硬件接口之间的数据通信实现技术,给出了数据通信的软件设计流程。CPLD(EPM7128)是用来调整时序和实现在线修改。实验证明了设计的可行性,探索了一种新的选煤技术。A novel coal gangues on-line recognition and automation selection system based on the ARM(advanced RISC machines) microprocessor and CAN(controller area network) bus is introduced in order to explore a new way for the coal dry selection technique. The design idea of the interface circuits between the ARM microprocessor and the CAN controller is discussed, and the flow chart of the communication between AT91M40800 and SJA1000 is given. In view of real-time, CPLD EPM7128 chip is used to modulate time sequence and update program on-line. Experiments show the design is satisfied with the accuracy requirements and the real-time performance.
