According to the development scheme of ground testing equipment for the satellite electric propulsion subsys?tem,a matched data acquisition and memory system is developed. The implementation of FPGA?based automatic variable rate ac?quisition in the LabVIEW language programming by slave computer is described. The realization method for link of the data?base with SQL database through LabVIEW is introduced. With data insertion and query,the system can provide human?machine interface in the PC monitoring computer and transform the acquisition rate automatically according the situation. The program?ming idea for each program VI is elaborated,which provides a new direction for computer automatic variable rate programming. The actual running result shows that the programming idea is novel and unique,and the system works well and can realize accu?rate acquisition.
