Embodiment Construction

[0027] The following is a detailed description through an example.

[0028] Assume that the original requirements of a test object in BIT are as follows:

[0029] It is necessary to test the BIT test stimulus; before performing the BIT test stimulus test, it is necessary to turn on the test stimulus permission switch and test whether the test wrap is correct when the test stimulus is 10V; at the same time, after the test wrap is over, it is necessary to test when the test stimulus permission switch is turned off After that, test whether the excitation wrap is 0V. Tests whether the stimulus allows switch wraparound to 0.

[0030] According to the above information, the test process is divided and described in a standardized manner, as shown in Table 2 and Table 3 below

[0031] According to the original requirements, the test is divided into 8 test steps, as shown in Table 1 below, and these actions need to be completed in order.

[0032] Table 1 Example table of test conten...

Abstract

The invention belongs to a computer technology, and relates to an automatic test method of a flight control system BIT (Built-in Test) based on object abstraction and an automatic test device of the flight control system BIT based on the object abstraction. The automatic test device comprises a data abstraction module, a translation module and a detection module, wherein the abstraction module is used for carrying out data abstraction on test objects, the translation module is used for translating information in requirement description texts of specification language to equipment instructions by using mapping specifications, and the detection module is used for driving equipment to be detected based on equipment instruction sets generated by the translation module. The method uses an abstraction method to describe requirements, so that the requirements are standard and accurate and free of confusion; customized script translation rules implement mapping of the requirements and codes to eliminate the possibility of manual code programming errors; scripts are used to scan the requirements to automatically realize the requirements so as to not only improve the efficiency but also ensure no errors.

Description

[0001] 1. Technical field [0002] The invention belongs to computer technology, and relates to an object abstraction-based flight control system BIT (in-machine self-test) automatic test method and an object abstraction-based flight control system BIT automatic test device. [0003] 2. Background technology [0004] As fly-by-wire flight control systems become increasingly complex, it is necessary to test all flight control components regularly or irregularly, and determine whether the aircraft can take off through the test results. At present, the software-driven hardware test method is used to complete the BIT test of the flight control system. The test process is to test all the components involved in the flight control system one by one in a certain order until all components are tested. [0005] But the above test method has the following problems: [0006] As the flight control system becomes more and more complex and the requirements for test coverage become higher and...
