Broadband communication network architecture combining train control network and train operation network and communication method thereof

摘要

A broadband communication network architecture combining a train control network and a train operation network, including a trusted network and an untrusted network. The trusted network is a reliable vehicle-level network element provided in each vehicle. And each of the leading vehicle and the last vehicle is provided with a reliable train level network element in addition to the reliable vehicle level network element, the untrusted network comprising the leading vehicle and Comprising an unreliable train level network element provided in the last vehicle, wherein one reliable train level network element is routed through a security gateway; Communicate with one untrusted train level network elements Te, and some security gateway is redundant to each other. The network architecture of the present application is a broadband communication network architecture that combines a train control network and a train operation network, which enables train control information, monitoring information and diagnostic information, and passenger information and video information in a combined network. Data from the passenger information provision system network and data from the train control network can be transmitted in the combined network, so that the demand for the bandwidth of the passenger information provision system network is satisfied, and The stability of the train network is guaranteed.
