高可管理性道岔融雪远动控制网络

Highly manageable remote control network for electric heating switch snow-melting system

为增强铁路道岔融雪系统的灵活性和可管理性,进行可控的远动中心分段监控,提出在远动控制网络上应用虚拟路由传输精简版(VRF-Lite)对网络路由信息分组,实现系统分段。在简易网络环境中进行了基于VRF-Lite的远动控制网络组网实验。实验结果证实,通过在路由器上进行软件配置,网络通信实现分组,分组结构灵活易控。由此得出,应用VRF-Lite技术不仅可使远动控制网络保持对融雪系统通信的支持,而且有效提升系统可管理性。该技术可作为融雪系统项目实施和系统优化的备选方案。

To enhance the flexibility and manageability of railway electric heating switch snow-melting system, engaging in controllable monitoring with remote control centers separated in sections, the application of Virtual Routing and Forwarding- Lite （VRF-Lite） on remote control network was proposed, which would divide the system into sections by grouping network routing messages. The experiment on building remote control network based on ~RF-Lite has been carried out on simple network environment, the results verify, through software configuration on routers, that the network communication is divided into groups, of which the framework is variable and easy to control. It is concluded that the implementation of VRF-Lite could not only make the remote control network still support snow-melting system communication, but also promote the manageability of system. This technology can be used as one of solution candidates in snow-melting system project implementation and system optimization.
