A method and system for acceptance of flight software of launch vehicle based on unattended operation

Abstract

An unattended carrier rocket flight software acceptance method, 1), using a real hardware interface to simulate and equivalent flight software external operating environment; 2), designing an automated test process for each type of acceptance test trajectory, and configuring test parameters; 3) For each acceptance test trajectory, the process control unit selects the matching test process from the test process library; during the execution of the test process, the required binding data and test case data are stored in the multi-function simulator; automatic arrow feeder Upload binding data, automatically send control commands to the arrow machine; control the working status of each simulator; control the operation stage and status of the flight software; collect, analyze, and interpret the test results in real time; 4), traverse all the acceptance test ballistics. At the same time, the invention provides a software acceptance system for a launch vehicle flight. The invention solves the problem of batch execution of unattended flight software acceptance test, and achieves the engineering application effect of software acceptance test being flexible, convenient, fast and economical.

Description

technical field [0001] The invention relates to an unattended-based carrier rocket flight software acceptance method and system, and belongs to the technical field of testing and testing. Background technique [0002] The launch vehicle flight software runs on the rocket computer and is used to complete the flight control functions such as guidance, navigation, attitude control, timing control, fault diagnosis, telemetry information organization, bus control, and triple redundancy management during the rocket flight process. core software. Flight software acceptance is a comprehensive functional performance test and verification of flight software to verify the correctness and reliability of flight software functions and performance. [0003] The flight software acceptance test case is a set of input data used before and after the launch vehicle takes off, and is used to evaluate the software response output of the flight software under different ballistic and deviation con...

AI Technical Summary

Problems solved by technology

At the same time, a normal model flight trajectory test takes about 1 hour, which takes a long time

The saving and replacement of test input data and the saving and storage of test results all require human intervention, which is prone to errors and seriously restricts the work efficiency of flight software acceptance testing
