数字加速度计多通道测试系统研究

Study of testing system for digital accelerometer

加速度计是惯性导航的重要敏感器件,其参数的好坏直接影响到惯性系统性能的高低。为提高加速度计检测效率与准确性,通过融合计算机总线通讯技术、模块化设计技术、组态软件技术和抗干扰技术,设计了加速度计多通道测试系统,详细说明了该系统的测试原理、系统设计过程及设计方案。经过对测试结果进行抽样检验,系统测试准确率达100%。

Accelerometer is an important sensitive apparatus of inertial navigation and its parameter value decides the performance of inertial system directly. In order to improve accelerometer＇ s detecting efficiency and veracity, this paper designs a muhicenter testing system of accelerometer by syneretizing computer bus communication technique, modular design technique, configuration software technique and anti-jamming technique. The paper explicates test principle, design process and design scheme of the system. By sampling test, testing veracity reached a hundred percent.
