一种试验场陀螺仪数据采集方法研究

A Study on Data Acquisition Method of Gyro in Testing Groud

本文针对挪威生产的STIM202高速率MEMS陀螺仪的数据采集方法进行了研究,采用一种新的LABVIEWE+MATLAB的混合编程方式,在LABVIEW中使用生产者与消费者循环,解决了高传输速率下一般采集方式中存在的缓冲区数据丢包问题,在MATLAB中进行批量数据运算,提高了效率,达到了数据采集中实时性和准确性的要求。该方法对其他的陀螺仪数据采集也适用,因此,为试验场下一步的惯性导航设备的数据采集提供了可行方法。

In this paper,the data acquisition method of STIM202is studied,that is high-speed Micro-Electro-Mechanical gyroscope made in Norway.A new mixed programming method of LABVIEWE and MATLAB is adopted,The producer-consumer cycle is used in LABVIEW,which solves the problem of data loss in buffer in general acquisition mode under high transmission rate,The batch data operation improves the efficiency and achieves the requirements of real-time and accuracy in data acquisition.This method is also applicable to data acquisition of other gyroscopes.Therefore,it provides a practical method for data acquisition of inertial navigation equipment in the Testing Groud.
