基于DSP和CAN总线的采煤机分布式控制装置

Distributed control device of coal shearer base on DSP and CAN bus

介绍了一种专为电牵引采煤机控制应用研制的基于高性能DSP(Digital Signal Process)控制器和CAN(Controller Area Network)总线的网络分布式控制装置。该装置由多个分布于采煤机不同部位的功能模块通过多条总线互连,分析了其基本结构与关键技术,对主要模块的软硬件设计实现做了详细介绍,并就实际应用的效果做了简要说明。

The paper introduced the network distributed control device base on the high performance DSP (Digital Signal Process) and CAN (Controller Area Network) bus specially for the research and development of the electric haulage coal shearer. The distributed device was interconnected with multi buses via functional modules in different locations of the coal shearer. The paper analyzed the basic structure and the key technology of the distributed device. The paper had a detail introduction on the hardware and soft...
