Scope

This part of GB/T28029 specifies the application specifications of the train communication network to achieve communication between application software through the marshalling network defined in GB/T28029.1 and the train backbone network defined in GB/T28029.6. This standard specifies the requirements for applications that communicate via marshalling network data transmission equipment on marshalling networks and train backbone networks. This section applies to applications on trains, that is, it contains application specifications belonging to the train control and monitoring system (TCMS) functions. The application specification is based on the TCN communication system for data communication between train groups. This section provides a data interface with TCMS function parameters and addresses based on the GB/T28029.4 communication protocol. This section applies to rolling stock requiring interoperable coupling and decoupling. When the supply and demand parties reach an agreement, this section can also be used for closed trains and multi-unit trains. Train communication network technology that complies with the definition of this section can achieve interoperability between train groups. Data communication systems within the marshalling are outside the scope of this part and are only given as examples of TCN solutions. In any case, proof of compatibility between the proposed train backbone network and the marshalling network should be given by the supplier. Special backup functions used when the train backbone network is in a degraded state do not fall within the scope of this part. Figure 1 The GB/T28029.5TCN application specification linking functions and applications is shown in Figure 1. This section aims to create a general model that describes the remote control of TCMS functions such as "controlling the car door" in a functional manner. This section directly references GB/T28029.4. This communication protocol covers data transmission on the Ethernet train backbone network and specifies the functions between groups (such as locomotives, multi-unit trains and control trailers) and the data necessary to establish transmission and processing. Message rules. 1GB/T28029.5-2020 This part specifies the application specifications for the following train functions: a) controlling doors; b) controlling traction; c) controlling braking; d) providing diagnosis. Note: Functions b)~d) will be provided in future revisions of this part.
