摘　　要：文章详细分析了RS485总线和Profibus DP总线的通信原理,并以煤矿供电自动化系统为例,介绍了采用ABC智能串行网关设计的RS485总线与Profibus DP总线的互联电路,并给出了ABC网关的参数设计和配置。实际应用表明,该互联技术使用效果良好。The paper analyzed communication principle of RS485 bus and Profibus DP bus in details. Taking an automation system of coal mine power supply as an example, it introduced design of inter- connection circuit between RS485 bus and Profibus DP bus using ABC gateway, and gave design of parameters and configuration of ABC gateway. The practical application showed that the interconnection technology had a good effect.
