以电压、电流、声音传感器和NI USB-6251 采集设备及计算机为硬件,以LabVIEW8.0 为软件开发平台,开发了陀螺信号数据采集系统。介绍了程序流程和设计技巧,可实时对8 路信号快速采集和存储,进而实现历史数据查询、波形回显及数据分析。该系统已投入使用,效果良好。 关键词: 虚拟仪器;LaVIEW;数据采集;USB;陀螺 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. Keywords: virtual instrument; LaVIEW;data acquisition;USB;gyro
