Abstract: According to the demand of multi-channel high-speed data acquisition and real-time control of the experiment model of pulse detonation engine(PDE), this paper designs and realizes a real-time measurement and control system based on virtual instrument technology. The hardware and software architecture system is introduced. The key techniques including anti-jamming technique, multi-thread programming and card control technology based on register are mentioned. Applications in practice indicate that it owns high real-time performance and dependability and it meets the needs of high-speed data acquisition and control time.

Key words: pulsed detonation engine(PDE), high-speed data acquisition, measurement and control system, virtual instrument technology
