| 摘 要： | 针对电气化铁道牵引供电系统的实际情况,给出了变电所信息综合传输方案的工作原理。借鉴电力系统信息综合数字化传输,构建起分层分布式的牵引变电所综合信息传输网络平台,给出一种通过控制发送方各类信息的传输速率来控制传输流量的方法和根据实时性要求的各类信息传输带宽的分配方法。将上述方法相结合,有效解决了牵引变电所信息综合传输的服务质量(QoS)问题。

| Abstract: | Working theory of comprehensive transmission plan is given according to practical situation of power supply system of electrified railway. Learning from SPDNet digitized comprehensive transmission plan, a distributed hierarchical traction substation information network is constructed. A method of constraining transmission flow by controlling different transmission rate for various types of information from the sender and a bandwidth allocating method of giving appropriate bandwidth to the information with different real-time properties are proposed. The ways indicated above connect, it can effectively solves the QoS of comprehensive information transmission. |
