* Replace the IEC 61156-1..2007 with the modified GB/T 18015.1-2017 adopting international standards (see 4.2.2, 4.2.3.1,

4.2.4).

* Replace IEC 61156-5 with GB/T 18015.5 equivalent to the international standard (see 4.2.2).

* Replace IEC 62236-3-2 (see 4.2.2, 4.2.3.1, 4.2.4) with GB/T 24338.4 modified to adopt international standards.

* Replace the IEC 61375-1..2012 with the modified GB/T 28029.1-2020 adopting international standards (see Chapter 1, 3.1,

4.4.1, 6.3.1, 6.3.2, 8.8.6, 11.6).

* Replace IEC 61375-2-3 with GB/T 28029.4 modified to adopt international standards (see 6.3.2, 8.4, 8.5.2.12, 11.6, 13.3).

* Replace IEC 61375-3-4 with modified GB/T 28029.12 that adopts international standards (see 6.2, 6.4.4, Chapter 9).

* Added reference to GB/T 28029.2-2020 (see 3.1 and 3.3.4).

* Removed ISO /IEC 7498 and ISO /IEC 9646.

* Replace IEC 61076-2-101..2012 with the international standard IEC 61076-2-101 (see Chapter 2).

--- Modified the terms and definitions, citing the terms and definitions defined in GB/T 28029.1-2020, GB/T 28029.2-2020 (see

3.1).

--- Added abbreviations CSMA/CD, LAN, SNMP and LLC, deleted abbreviations CSTINFO,

XML, MTU (see Chapter 3).

--- Modified the description of type C in Table 4 and forced the use of contradictions with C (see Chapter 5).

--- Modify the formula (1) in 6.5.3.2 to "O = (destination device grouping network identifier-source device grouping network identifier 64) mod64" to

This corresponds to the example of relative addressing shown in FIG. 22.

Introduction

This part of GB/T 28029 defines the Ethernet train backbone network to realize the different types of marshalling when connected in the same train composition

Interoperability.

This part complies with the ISO -OSI model and specifies the entire protocol stack from the physical layer to the application layer.

The Protocol Implementation Conformance Statement (PICS) allows suppliers to declare their compliance with this part. PICS specifications and related conformance tests are not

The scope of this section.

Rail Transit Electronic Equipment Train Communication Network (TCN)

Part 2-5. Ethernet Train Backbone (ETB)

1 Scope

This part of GB/T 28029 specifies the Ethernet Train Backbone (ETB) requirements to meet open trains based on Ethernet technology

Communication Systems.

Regardless of the marshalling network technology used (see GB/T 28029.1-2020), this section implements interoperability between local marshalling subnets.

All marshalling network definitions should consider this part to maintain interoperability.

When the supply and demand sides agree, this section can be applied to closed trains and multi-unit trains.
