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

Abstract

The invention discloses a design method for the anti-collision software test scene of the airborne anti-collision system in the system test. Step 1 obtains the composition and operation mode of the anti-collision system, and constructs a software system-level test environment; Step 2 decomposes the standard test scene description file. Input data and extract valid information; migrate the input information of the anti-collision software from the internal interface to the external interface according to the system function and internal and external interface information, so as to meet the software system-level test input requirements; construct the S-mode transponder DF message information , ground station UF message information and local machine information; Step 3 applies the test data constructed on the built software system test environment, utilizes the traffic / decision display and the warning loudspeaker to output the traffic decision warning result, and compares the result with the simulation output The results are compared to verify whether the standard test scenario can pass in the software system test. This method is based on the test scene description of the anti-collision software in the DO-185A standard, and improves the level of software testing.

Description

Technical field [0001] The present invention belongs to the field of airborne collision avoidance system software testing, particularly relates to the airborne collision avoidance system collision software testing scenario in the system testing method. Background [0002] The airborne collision avoidance system effectively tracks and monitors aircraft equipped with air traffic control transponders in the nearby airspace, completes the acquisition and calculation of the distance, speed, flight altitude, orientation and other information of the target aircraft, and correctly generates traffic alarms according to the trajectory of the target, or further generates a decisive alarm according to the degree of threat. Traffic warning and decision warning information are provided to the pilot in the form of voice and display on the 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 equippe...

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
