[0002] As the level of intelligence of rail transit trains gradually improves, the amount of train control data increases further, and real-time Ethernet technology is rapidly used on trains. The train TCMS system uses real-time Ethernet as the communication basis to build the entire communication network of the train. The train's traction system, braking system, on-board signal system, door system, air conditioning system, passenger information service system, etc. are all connected to this network, communicating with each other to complete the train control of the entire vehicle.

[0003] In order to ensure the safety and reliability of the train control, the control logic of each system of the train needs to be tested during the development and maintenance process. It is necessary to build a simulation test environment between the control systems of the train.

An Ethernet switch is used for the many-to-one system test;

[0041] The companion test device and the main test device are connected via Ethernet and use the same communication protocol, such as UDP or TCP / IP or TRDP. At the same time, the devices need to be in the same local area network to ensure normal communication.

[0042] The device to be tested can be an ordinary Windows system PC or an industrial device with a display screen and interactive operation under the Linux system. The device to be tested is built-in with a green and installation-free software for being tested, which is a self-developed software based on this method. It can read configuration files in a certain format, and the configuration file format is:

[0043] <?xml version="1.0"encoding="utf-8"?>

[0044] <CTCMS CCU ID="1"Name="CTCMS CCU">

[0045] <output childtype＝"ctcms item">

[0046] <CTCMs Item ID="1" Description="Life signal byte" Byte offset="0" Bit offset="0” Type="3” NameStr="TCIR LIFESIGNAL HIGH"

[0047] < / output>

[0048] <input ChildType＝"CTCMS Item">

[0049] <CTCNs Item ID-"1"Description="Life signal byte"Byteffset="0"Bitoffset="0”Type="3”Default="0”NameStr="LIFESIGNAL HIGH" / >

[0050]

[0051] < / CTCMS CCU>

[0052] The configuration file is in xml format. The software obtains the offset bytes, offset bits, data types, etc. of the data according to the keywords in the xml; according to the configuration file, the software for being tested can automatically generate a corresponding display and interaction interface. The display and interaction interface is as Figure 4 shown. The table part in the interaction interface corresponds to the data in the xml.

[0056] Example 2, as another implementation of the present invention, the portable train full system simulation test method provided in the embodiment of the present invention is applicable to the simulation test between various systems of the train, and the test objects can be freely matched according to the needs. The specific implementation process is as follows:

[0057] The companion test device and the main test device are connected via Ethernet and use the same communication protocol, such as UDP or TCP / IP or TRDP. At the same time, the devices need to be in the same local area network to ensure normal communication.

[0058] The companion test device has built-in companion test software, which can read configuration files in a certain format, automatically generate corresponding display interaction interfaces according to the configuration files, regularly send and receive data on the Ethernet bus, and display them in real time. According to the test content, the user can enter relevant data, and after clicking OK, the companion test software can send the data to the network, which will be received by the main test device. After the main test device performs logical processing, it will send the logical results to the network, which will be received and displayed by the companion test software.

[0059] The following uses the traction system and brake system as the accompanying test equipment and the TCMS controller as the main test equipment as an example to introduce the usage method. In order to be consistent with the actual situation as much as possible, the traction system and brake system are tested using two accompanying test equipment instead, including:

[0060] (1) Use two accompanying test PC devices to replace the traction system and brake system. The two accompanying test PC devices and the TCMS controller are connected to the Ethernet switch at the same time, and the device IP is set to ensure normal communication;

[0061] (2) According to the communication protocol between the traction system and the TCMS system, and between the braking system and the TCMS system, two configuration XML files are generated using Python: the protocol is usually in Excel format and does not contain information such as keywords. It does not conform to the XML format and cannot be used directly. Use Python to read the Excel content, add keywords according to the information in each column, and write the composed string into the XML file in XML format;

[0062] (3) The accompanying test software of the two accompanying test PC devices respectively use the XML configuration file in step (2) to copy and replace the existing XML file in the software path, start the accompanying test software, and the accompanying test software can receive the relevant data of the TCMS controller;
