A method of testing information processing for the launch vehicle control system

摘要

The flight control system is the most important system of a launch vehicle, so strict and comprehensive tests must be carried out on it. As for the control system of a new type of launch vehicle, it brings more signals and information than before. In order to ensure the reliability of data acquisition and real-time processing of testing information, a new method of concerted multi-card acquisition and testing Information processing is presented in this paper. In particular, a software based adjustable frequency sampling and storage method for analog signals is introduced in detail. Corresponding test system has been developed and applied to real launch task, and testing conflicts are avoided, testing flexibility is improved.
