This part replaces GB/T 28029.2-2011 "Traction bus of traction electrical equipment Part 2. Train communication network consistency test Compared with GB/T 28029.2-2011, the main technical changes in the content of WTB conformance test in the test are as follows. --- Modify "connection resistance" to "contact resistance" (see 5.3.9.3.4,.2011 version 4.1.2.9.2.3); --- Modify "test procedure" to "test suite" (see 4.1, 4.2.5.2, 4.3.5, 4.3.6.1, 5.6.2.6, 5.6.2.14, 5.6.3.1, 6.1, 7.3, Chapter 8, B.2.1 ~ B.2.5, B.3.3, B.3.4, B.4.2.2, B.4.3.1, B.4.3.2, C.1,.2011 version 4.1.6.7 , 4.1.6.14, Chapter 5, 6.3, Chapter 7, A.2, A.3, A.4.2, B.1.1.1). This part uses the redrafting method to modify the adoption of IEC 61375-2-2..2012 "railway electronic equipment train communication network (TCN) Part 2-2. Conformance testing of stranded train buses. " Compared with IEC 61375-2-2..2012, this part has more structural adjustments. Appendix A lists this part and IEC 61375-2-2. A comparison list of chapter numbers in.2012. Compared with IEC 61375-2-2..2012, there are technical differences between this part and the clauses 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. --- Added the content of "Regulations" in the scope to meet the requirements of GB/T 1.1 (see Chapter 1). --- 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. ● Replace ISO /IEC 9646-1..1994 with GB/T 17178.1 equivalent to international standards (see 3.1, 4.1); ● Replace ISO /IEC 9646-7..1995 with GB/T 17178.7 equivalent to international standards (see 4.1); ● Replaced IEC 60571 with GB/T 25119 modified to adopt international standards (see 4.3.8, 5.3.2); ● Replaced IEC 61375-2-1 with modified GB/T 28029.2-2020 adopting international standards (see 3.1, Chapter 4 to Chapter 7 Chapter, Appendix B and Appendix C); ● Added reference to GB/T 28029.4 (see 5.6.3.20); ● ISO 7498 has been deleted. --- Increase the method of measuring the insertion loss using the network analyzer, after the test verification and analysis, use the network analyzer to measure the insertion The loss test accuracy is higher, and the test environment has less effect on the test results (see 5.6.1.3.1). --- Deleted part of the test, because "configuration fixture 1 (configuration fixture 1) and configuration fixture 2 are not defined in the standard (configurationfixture2) "(see 5.1.5.6.2 and 5.1.5.6.3 of IEC 61375-2-2..2012). --- Modify the "Note" of Table 29 to paragraph, because the table note contains the requirements (see 5.6.2.12). --- Modified the content in Table 35, and changed the "user to master device" in lines 3, 4, 6, and 7 to "master device" P09 change user report request detected "" Master device detected P10 change user report request "" Master device detected P09 "Change user report request" "The master device detected a P10 change user report request" to make the description of the expected results in Table 35 clearer (See 5.6.3.3). --- Modified the content of Table 42 and changed the "Check about sink time monitoring status of node P11" on line 4 (checkaboutsinktime supervisionofnodeP11) "is modified to" the process data polling sent to P11 has no response, corresponding to the sink end of the P11 node The port refresh monitoring bit is 1 ”, and the“ check about the sink time monitoring status of node P10 ”(checkaboutsinktime supervisionofnodeP10) "is modified to" the process data polling sent to P10 has no response, corresponding to the sink end of the P10 node The port refresh monitoring bit is 1 ”to make the description of the expected results in Table 42 clearer (see 5.6.3.10). --- Added the content of Table 45, Step 2, Step 4, Step 6, Step 8, Step 11, Step 13, Step 15, Step 17 were added Add "Set P01 as weak master", "Set P32 as weak master", "Set P10 as weak master", "Set P32 as weak master", "Set P01 as weak master" "Main" "Set P32 as weak main" "Set P10 as weak main" "Set P32 as weak main". Because according to IEC 61375-2-2. In the.2012 step operation, there will be two network couplings with a strong master in step 5, step 9, step 14 and step 18 respectively In the combined situation, it is expected that the two networks will not couple (see 5.6.3.12). --- Added the operations in steps 4 and 5 in Table 49 to ensure that P10 is the master device in step 6 (see 5.6.3.16). --- Deleted the relevant description of PICS form in 7.2, because the relevant PICS expression has been carried out in Chapter 5 (see 7.2 of IEC 61375-2-2..2012). --- The following description has been added to the "Test of Marshalling Node Type 'Strong Master'". WTB cables (including A and B wires) will be used Group 1 is connected to tester direction 1 (see 7.3.3.2.3). --- "The pulse sequence of about 50 μs should be observed every (25.0 ± 4.0) ms on the WTBA line and the B line [Pulsese- quencesofapproximately50μsevery25ms (withatoleranceof ± 4.0ms) shalbeseenon theWTBlinesAandB.] "is modified to" It should be observed that about every (50.0 ± 4.0) ms on the WTBA and B lines There is a pulse sequence of 50 μs. "Because the WTB bus master sends to the end nodes in direction 1 and direction 2 every 25ms There is a request frame.After receiving the presence request frame, the end node sends a detection request frame on its auxiliary channel. For a single end node, the detection request frame transmission period should be 50ms (see 7.3.3.2.2, 7.3.3.2.3, 7.3.3.2.4). This section also made the following editorial changes. --- Removed acronyms not used in this section (see Chapter 3); --- Modify Note 1 and Note 2 in 5.6.2.11 to Table 28; --- Modify GB/T 28029.2-2020 4.4.2 to 4.3.2 (see 7.2.2.3); --- Modify all "1 end" in the test instrument connected as follows to "2 end" (see 7.3.2.4); --- Modify IEC 61375-2-2..2012, 5.1.2.6, Table 11, line 1 4.1.4 ~ 2.1.5 to "4.2.4, 4.2.5", because IEC 61375-2-2..2012 is wrong (see 5.3.6); --- Modify 2.2.4.3 in 5.1.5.1.1 of IEC 61375-2-2..2012 to 4.3.4.3, because IEC 61375-2-2..2012 is wrong (See 5.6.1.1); --- Modify the output signal value 0.300V to 3.000V, because IEC 61375-2-2..2012 is wrong (see 5.6.1.6.2.4); --- Modify "P11" on the 6th line of Table 39 to "P09", because IEC 61375-2-2..2012 is wrong (see 5.6.3.7) --- Modify "2.6.3.3 ~ 2.6.3.6" to "4.7.3.3 ~ 4.7.3.6" because IEC 61375-2-2..2012 is wrong (see 7.3.3.3); --- Added table questions; --- Adjusted the sequence of table 55 and table 57 (see 7.2.2.2 and 7.2.2.4); --- Adjusted some column numbers (see 4.1, 4.2.2, 4.3.2.2, 4.3.3.2, 4.4.2, 5.6.1.3.1, 5.6.1.6.2.4, 5.6.1.6.2.5, 5.6.1.6.3, 5.6.1.6.4, 5.6.2.2, B.1.1, B.1.2).

Introduction

The TCN train communication network standard is a national standard with the goal of defining interfaces to achieve. a) Insert compatibility between devices located in different groups; b) Insertion compatibility between equipment and devices located in the same group. One of the key success factors for developing any technology is standardization and ensuring interoperability between different implementations. To facilitate interoperability, execute Conduct consistency testing. In this part of GB/T 28029, pay attention to the train Line, other buses already foreseen in GB/T 28029 are not considered. WTB provides two real-time protocols for communication services. a) Process variable transmission, a distributed real-time database, periodically refreshed in a broadcast manner; b) Message delivery, send in one of the following ways as needed. ● Unicast messages (point-to-point); ● Multicast messages. WTB has a network management function, which allows debugging, trial operation and maintenance through the network. This part is divided into 8 chapters and 3 appendices.
