Embodiment 1

[0044] figure 1 It is a schematic structural diagram of the test system of the on-board equipment for train control in this embodiment. The test system mainly includes a test script generation module 103 , a protocol encapsulation module 104 and an interface adaptation module 105 . The test script generation module 103 is connected with the protocol encapsulation module 104 , and the protocol encapsulation module 104 is connected with the interface adaptation module 105 .

[0045] Wherein, the test script generation module 103 is used to generate at least one test script according to the test mode and the type of the device under test, and send the test script to the protocol encapsulation module 104 . The protocol encapsulation module 104 encapsulates the test script based on the protocol type of the device under test, and generates test command data conforming to the protocol of the device under test. The interface adaptation module 105 converts the test command data into ...

Embodiment 2

[0058] Image 6 It is a flow chart of the steps of the test method of the train control on-board equipment in this embodiment. like Image 6 Shown, at first, generate at least one test script (step S601) according to test pattern and DUT type; Then, test script is encapsulated based on the protocol type of DUT, generate the test order data (step S601) that meets DUT protocol S602); converting the test command data into a test instruction sequence adapted to the connection interface of the device under test (step S603), and sending it to the device under test. Preferably, it also includes receiving test result data fed back from the device under test (step S604), for analysis by test personnel.

[0059] Wherein, in step S602, in order to realize a more flexible test function, at least one test script can be selected for the protocol encapsulation module according to the test requirements first, the selected test scripts are sorted according to a predetermined order, and then ...

Abstract

The invention discloses a testing system and testing method of a train control on-board device. The testing system comprises a testing script generating module, a protocol packaging module and an interface adaptive module. The testing script generating module is used for generating at least one testing script according to testing modes and the type of a tested device. The protocol packaging module is used for packaging the testing scripts on the basis of the protocol type of the tested device and generating testing command data according with the protocol of the tested device. The interface adaptive module is used for converting the testing command data into a testing command sequence adaptive to a connection line interface of the tested device. According to the testing system and testing method of the train control on-board device, script compiling, script protocol conversion and testing command sending are set to be independent function parts, the decoupling effect of the function modules is achieved, a more flexible testing function can be provided, and extensibility is high.

Description

technical field [0001] The invention relates to the technical field of testing a train control system, in particular to a testing system and a testing method for a train control vehicle-mounted device. Background technique [0002] The existing CTCS train control system includes train control vehicle equipment and train control ground equipment. The on-board train control equipment receives the train control information through the transponder in the ground equipment and the track circuit, generates a train control curve according to the train control information, and supervises the safe operation of the train through the train control curve. Among them, the CTCS-2 train control system can only guarantee the safe operation of trains with a maximum speed of 250km / h, and the CTCS-3 train control system can meet the high-speed driving requirements higher than 250km / h. [0003] In order to ensure the safety of the system, new equipment needs to be fully tested before being inst...
