Design and Implementation of Spacecraft Telecommand Quickly Generation System Based on LUA Script

摘要

During the test of the spacecraft, a large number of telecommands need to be injected to verify the correctness of the functional performance. In order to improve the efficiency of telecommand generation and use, this article designs a Lua script-based telecommand quickly generation system. Use Lua language to abstract the model and generation algorithm of various telecommands, design a universal telecommand description method, and shield the variety of telecommand data format diversity; Through the interface functions of C and Lua, the Lua interpreter is compiled into the spacecraft test platform, Interprets and executes Lua scripts to achieve quickly automatic telecommand generation and real-time injection. According to the actual test of a satellite, this method can abstract more than 300 telecommand templates for 4 Lua scripts, and reduce telecommand generation time by more than 90%, greatly improve the efficiency of test verification. It also provides reference methods and practical tools for improving the flexibility of spacecraft telecommand generation.
