传统的驼峰控制系统是按分布式设计的,但设备布置相对集中。系统网络多采用2级异构形式,一层为诸如Bitbus,Canbus等标准的低速现场总线网络,另一层为传统以太网。随着驼峰控制系统功能需求的不断增加,系统通信的信息量迅猛增长,原有网络不堪重负,成为性能瓶颈。同时通信程序越 The traditional hump control system is distributed design, but the device layout is relatively concentrated. The system network mostly adopts two levels of heterogeneous forms, one is a low-speed field bus network such as Bitbus and Canbus and the other is a traditional Ethernet. With the increasing demand for the functional requirements of the hump control system, the amount of information for system communication is rapidly increasing, and the original network is overwhelmed and becomes a performance bottleneck. At the same time the more communication procedures
