Problems solved by technology

Generally, the method of observing through the method of display and monitoring variables cannot save data in real time, and the accuracy is poor. At the same time, the time of human eyes and reflection ability cannot reach the millisecond level and is prone to fatigue, and the accuracy of test results is poor.
This method of observing results has the disadvantages of poor real-time performance and lack of continuity in data, and it is easy to cause errors when testing some control function points, which will reveal defects to the site and reduce the quality of the product.

Embodiment 1

[0041] This embodiment provides a system for testing the software of the train control system based on event and fault record data, such as Figure 5 As shown, it includes the tested module, the accompanying test module, the event recording module for recording input and output data, and the PC loaded with analysis software; the tested module, the accompanying test module, and the event recording module are connected sequentially through the MVB bus; the PC The machine adopts serial port or Ethernet to connect with the test module and the module under test respectively.

[0042] The tested module is tested through the test companion module, and the real-time test results are recorded in the event record module, which is downloaded and analyzed by a PC loaded with analysis software, and the test results are reliable and accurate.

Embodiment 2

[0044] Such as figure 1 As shown, in the existing test method, after inputting data according to the test case on the accompanying test software, the test result can only be viewed through the method of display and monitoring variables, which cannot save data in real time and has poor accuracy (such as display The displayed speed can reach up to 0.1s), while the human eye and reaction time cannot reach the millisecond level and are prone to fatigue, and the accuracy of the test results is poor. This method of observing results has poor real-time performance, lack of continuity in data, and cannot know the analysis process, nor can it judge the error situation in the test process. When testing some control function points, it is easy to cause errors and reveal defects to the site, which reduces the quality of the product.

[0045] Such as image 3 and Figure 4 As shown, the present embodiment provides a method for testing the train control system software based on event and...

Abstract

The invention discloses a train control system software test system and test method based on event and fault record data. The testing method comprises the following steps: S1, acquiring software requirements and testing environment requirements; S2, compiling a test case and accompanying test software; S3, executing the test case; S4, inputting parameters according to the test case on the accompanying test software; S5, recording input parameters and output parameters in a data recording module; and S6. using analysis software to analyze test results. The method has the advantages of real-time, high precision, high continuity and high accuracy in the analysis and comparison of test results.

Description

technical field [0001] The technical field of software testing of the present invention, more specifically, relates to a train control system software testing system and method based on event and fault record data. Background technique [0002] With the increasingly higher requirements of the train control system in terms of stability, reliability, real-time performance, security, etc., the quality requirements of the train control system software, including transmission and network control system software, are becoming more and more stringent. The system software must pass the corresponding software test before it is put into operation. [0003] The software testing system of the train control system is generally composed of a module under test and an accompanying module. The accompanying software and driver software are written to run on the accompanying module and the module under test respectively. Such as figure 1 As shown, the usual method of testing the software of ...
