CAN与RS485通信在矿用机车斩波调速控制系统中的应用

摘要

为保证矿用机车斩波调速系统正常运行,在CAN通信与RS485通信比较分析的基础上,提出以DSP2812为控制核心的通信网络系统,其中控制信号传输采用CAN网络,显示信息采用485通信。该系统经试验和运行结果表明,通信系统可靠,能满足井下使用的要求。%In order to ensure the normal operation of mine locomotive chopped wave speed-governing system,on the basis of analyzing and comparing CAN and RS485 communication,the communication network system with the control core of DSP2812 is proposed.The control signal communication uses CAN network,the information shown uses RS485 communication.By testing and operation results,the system proves reliability and meets the underground mine using requirement.
