Compared with IEC 61375-3-4..2014, there are technical differences between this part and the terms involved in these differences have been passed on the outside margin.

The vertical single line (|) in the white position is marked. The specific technical differences and the reasons are as follows.

--- With regard to normative quotation documents, this part has been adjusted with technical differences to adapt to China's technical conditions and adjustments

The situation is reflected in Chapter 2 "Regulatory Reference Documents", with specific adjustments as follows.

* Removed ISO /IEC 7498, ISO /IEC 8824;

* Replace IEC 61156-6 with GB/T 18015.6 equivalent to international standards (see Table 12, 4.9.4.2, Table 14);

* Replace ISO /IEC 11801 with GB/T 18233 equivalent to international standards (see Table 12, 4.9.4.2, Table 14,

4.10.2.2);

* Replace IEC 61375-1 with GB/T 28029.1 modified to adopt international standards (see 3.3, 4.2.2, 4.3, 4.11.1);

* Replace IEC 61375-2-1 with GB/T 28029.2 modified to adopt international standards (see 3.1, 4.12.2, Chapter 5);

* Replace IEC 61375-2-5 with GB/T 28029.6 modified to adopt international standards (see 4.6.2, 4.7.2, 4.7.3, 4.11.2,

4.12.3, Chapter 5);

RFC3022, IETFRFC3203, IETFRFC3376, IETFRFC4541 are adjusted to normative references, to

Meet the requirements of GB/T 1.1 (see Chapter 2).

--- Deleted the terms and definitions defined in GB/T 28029.2, and directly quoted GB/T 28029.2.

--- Added the term and definition of "group switch" (see 3.1.12);

--- The note in Chapter 5 of IEC 61375-3-4..2014 is adjusted to the main text because it contains requirements.

This section also made the following editorial changes.

--- Added the table number and table title of Table 8 and Table 9;

--- Adjusted some column numbers (see D.1, D.3.2.3.2).

This part is proposed by the State Railway Administration.

Introduction

The TCN general architecture (see GB/T 28029.1) defines a two-layer network structure. a train backbone network and a marshalling network. The hierarchical structure provides

Based on different technologies such as MVB, CANopen and ECN, they can be connected to the same train backbone network. Based on not

ECNs of the same design and implementation can be interfaced to the same train backbone network, which ensures interoperability between marshalling networks of different implementations.

The general part of this part of GB/T 28029, namely Chapter 1 ~ Chapter 4, defines all ECN implementations, terminal equipment and gateways common

Requirements and specifications.

This general part defines.

--- Data communication interface of terminal equipment connected to ECN;

--- ECN provides functions and services to terminal equipment;

--- Gateway function for data transmission between train backbone network and ECN;

--- ECN performance.

Rail Transit Electronic Equipment Train Communication Network (TCN)

Part 3-4. Ethernet Marshalling Network (ECN)

1 Scope

This part of GB/T 28029 specifies the intra-group data communication network based on Ethernet technology, namely the Ethernet group network (ECN).

The application of this part can realize the interoperability of the equipment in each vehicle in the open train.

If the supplier agrees with the user through consultation, this section may also apply to closed trains and multi-unit trains.
