Aiming at the shortcoming of traditional test equipment, and in order to meet the new launch vehicle’s demands for control system test, a new method of integrated test for control system signals is studied. Aiming at the standardization and modularization of software, an overall design of software is put forward. The function structure and run mode of the new test system is described. The information flow of system is concluded and analyzed through software engineering method. Acquisition plans of different kinds of signals are determined, and the flow of multiplex signals acquisition is brought forward. The practical application proves that the system has stable performance and high integration level, and the efficiency and informationization level of ground test are enhanced effectively.
