摘　　要：在工矿自动化远程控制通信中,一部分通信结构采用的RS485总线方式。但是由于控制系统各异,通信协议不同,这些不同的RS485通信线路很难融合起来。因此,提出了一种RS485穿透以太网技术。它以以太网线路为基础,在不破坏已有RS485通信方式结构的基础下,把原有RS485通信线路融合起来,既避免了多条线路同时存在,又可实现基于IP的无地域的访问。During the remote automatic control communication, the partial communication structure uses RS485 bus. But it is difficult to blend these different RS485 lines because of different control systems and communication protocols. Therefore, the paper introduces a new technology-RS485 penetrating Ethernet. Based on the initial communication structure, it blends RS485 lines taking Ethernet as foundation, which avoids the simultaneous existence of the multi lines and realizes the unlimited IP-based visit.
