Design method of anti-collision software test scene of airborne anti-collision system in system test

Abstract

The invention discloses a method for designing an anti-collision software test scene of an airborne anti-collision system in a system test, and the method comprises the steps: 1, obtaining the constitution and operation mode of the anti-collision system, and constructing a software system-level test environment; 2, decomposing input data in the standard test scene description file, and extracting effective information; according to system functions and internal and external interface information, anti-collision software input information is migrated from an internal interface to an external interface, so that the anti-collision software input information meets software system-level test input requirements; s-mode responder DF message information, ground station UF message information and local information are constructed; and step 3, applying the constructed test data to the constructed software system test environment, outputting a traffic decision alarm result by using a traffic / decision display and an alarm loudspeaker, comparing the result with a simulation output result, and verifying whether the standard test scene can pass the software system test. According to the method, the test scene of the anti-collision software is described based on the DO-185A standard, and the software test level is improved.

Description

technical field [0001] The invention belongs to the field of software testing of an airborne anti-collision system, and in particular relates to a design method of an anti-collision software test scene for an airborne anti-collision system in system testing. Background technique [0002] The airborne collision avoidance system effectively tracks and monitors the aircraft equipped with air traffic control transponders in the nearby airspace, and completes the acquisition and calculation of the distance, speed, flight altitude, azimuth and other information of the target aircraft. Generate a traffic warning, or further generate a decisive warning based on the degree of threat. The traffic warning and decision warning information are provided to the pilot in the form of voice and display at the same time, reminding the pilot to take measures in time to avoid danger and prevent collisions with other aircraft; when both sides are equipped with anti-collision systems, the S mode d...

AI Technical Summary

Problems solved by technology

However, it is very difficult to construct complete software system-level test data

The main reason is that the anti-collision system software is very complex, it is difficult to prove that the test data constructed is sufficient, and the expected output of the test case cannot be given
