Software structure and design concept of the control system for the newly built rocket
engine test stand are presented.The system applies the PXIbus,the modular instrument,LabVIEW
DSC and LabVlEW RT,and realizes the function of sequential control,pressure regulating control,
signal dynamic detection and dynamic display of test process under muhiconditions of rocket engine
ground tests.The new system is characterized by high reliability and safety,real time,easy operation
and maintenance,better visualization.
