▍System features
● | The low-frequency modulation networks and ring redundancy technology are adopted to build the high-speed train redundant digital backbone network communication platform to achieve the auto-reconfiguration of networks after the train marshalling and unmarshalling. |
● | The power of key equipment is of the main-standby mode, and the dynamic load balancing technology is adopted in normal operation with the dual powers in parallel to evenly distribute the load current, improve power efficiency and reduce heat. |
● | The integrated management communication platform achieves the centralized control of multi-service flows through the gateway. The gateway encapsulates 485, current loop and other means of communications into IP package, so as to get rid of the information isolated island. |
