通过对某型加速度计测试系统现状的分析,设计了基于GPIB总线技术的加速度计测试系统,根据测试原理确定了数据采集系统的组成,根据加速度计的输出与其静态模型方程系数的关系,构建了加速度计性能分析平台,论述了测试数据的采集与处理方法、并利用Access数据库实现了数据的存储和调用。最后,利用MATLAB工具,建立了加速度计性能参数模型,并做出了相应的预测和差值估计。

The situation of the test system of accelerometer is analyzed, testing system for accelerometer based on GPIB is designed, and the composition of the data acquisition system is ensured in terms of test principle. The performance analysis platform of accel-erometer has been constructed according to the relationship between its output and coefficient of static model equation. The method of test data acquisition and processing, and how to realize the storage and calling of the data through Access have been discussed in detail. Finally, with the help of MATLAB tool, the accelerometer's performance parameters model has been built, and the corre-sponding forecasting and differential evaluation has been done.
