Abstract: With the hardware of voltage, current, audio transducers ,NI USB-6251 data
acquisition instrument and the computer ，and the software of LabVIEW 8.0, the data acquisition system for signal of gyro was built. Introduce flowing of the program and the design skill, the system can acquire and save eight channels signal quickly on real-time, further inquire about historical data, display wave and analyze data. The system has been put into practice and run well.
