Embodiment 1

[0041] Such as Figure 1-6 Shown, a kind of automatic test method of communication protocol conformance is used for testing the consistency of the communication protocol of each part of the train, each part of the train is connected by MVB mode, each part of the train to be tested is provided with a general protocol signal mapping module, the The communication protocol consistency automated testing method comprises the following steps:

[0042] S1: Each component establishes a connection with the test environment end industrial computer:

[0043] The components of the train to be tested are connected to the switch through Ethernet (ETH), and the switch is connected to the test environment end industrial computer for communication protocol conformance testing through Ethernet (ETH);

[0044] S2: Generate a test signal:

[0045] The train component to be tested transmits the MVB data to another train component to be tested, and the other train component to be tested transmits ...

Embodiment 2

[0059] Such as Figure 7 As shown, the communication connection between the test environment end industrial computer and the train components to be tested can also establish data interaction with each train component to be tested through the ETH to MVB module. With this solution, each train component to be tested needs to open the MVB port to build the test system. At this time, the train component to be tested only needs to pass the MVB data stream to perform data interaction with other components to be tested or the industrial computer at the test environment end.

Abstract

The invention provides an automatic test method for communication protocol consistency. A test environment terminal industrial personal computer performs data communication with components of a to-be-tested train, and all signal coercion and result judgment are processed on test environment terminal software to avoid the change of program source codes of the components of the to-be-tested train. Meanwhile, more components on the train can be added to perform the communication protocol consistency test so as to achieve a joint test of communication protocol consistency of a plurality of component devices in the train. By adoption of the method, fast verification of communication protocols with changes can be achieved, the potential quality hazard caused by the communication protocol inconsistency between the components due to protocol changes is solved, and the problem is exposed to the test environment in advance and is effectively solved. Meanwhile, by adoption of the method, the pressure brought to software change under the control condition of limited onsite time of a user can be effectively solved, it can be ensured that no major quality accident is generated onsite, the debugging period is shortened, the debugging risks are reduced, and the product reliability is improved.

Description

technical field [0001] The invention relates to the field of train communication testing, and more specifically, to an automatic testing method for communication protocol consistency. Background technique [0002] With the rapid development of the rail transit field, the functions of rail transit products are becoming more and more complex, and the reliability requirements for rail transit products are also getting higher and higher. Software is an important part of rail transit products, and the quality and reliability of software directly affect the reliability of rail vehicles. The communication protocol consistency of each component in the system is the premise of the system software test. Through the consistency test of the communication protocol, the protocol defects or failures in the software between the components in the system can be effectively found, which is the primary guarantee to ensure the quality of the system. [0003] The communication protocol test amon...
