Introduction

This section aims to.

--- Establish complete communication requirements for all train applications and list them in standard form;

--- Provide guidance for technical solutions for communication between application software on the same or different formations, which are train components

And connected to the relevant marshalling network and train backbone network;

--- Define the application specifications for the train functions involved in this section.

Rail Transit Electronic Equipment Train Communication Network (TCN)

Part 2-4. TCN Application Specification

1 Scope

This part of GB/T 28029 stipulates the application specifications of the train communication network, in order to achieve the application software through GB/T 28029.1

The defined marshalling network communicates with the train backbone network defined in GB/T 28029.6.

This section specifies the requirements for the application of communication between the marshalling network and the train backbone network via data transmission equipment of the marshalling network.

This section applies to applications on trains, that is, application specifications that include the functions of train control and monitoring systems (TCMS). Application Regulation

Approximately based on the TCN communication system used for data communication between train formations. This part provides a protocol based on GB/T 28029.4 communication protocol.

Data interface for TCMS function parameters and addresses.

This section applies to locomotives that require interoperable interlocking and unlinking. When the supply and demand parties reach an agreement, this section can also be used to close

Trains and multi-unit trains.

Complying with the train communication network technology defined in this section can achieve interoperability between train groups.

The data communication system within the group does not belong to the scope of this part, and is only given as an example of TCN solution. In any case, build

The compatibility certificate between the proposed train backbone network and the marshalling network should be given by the supplier.

The special backup function used when the train backbone network is in a degraded state does not belong to this category.

Figure 1 GB/T 28029.5TCN application protocol of link function and application

As shown in Figure 1, this part aims to create a general model to describe in a functional way the functions of TCMS functions such as "control of doors"

remote control. This part directly quotes GB/T 28029.4, the communication protocol includes 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 rules for establishing and processing the necessary data messages are established.
