基于角速度传感器的火炮调炮速度测量系统

摘要

At present, the instruments used for measuring the artillery angular velocity are huge in size, complex in installation, excessive connections, and requesting higher technical level in operation and can only measure the average velocity. In accordance with this situation, the portable system for measuring the real -time angular velocity is developed based on the high precision angular velocity sensor and the technology of virtual instrument. Hardware structure and software design of the system are described. Through the turntable in different angular velocity testing experiment proves the system stable work, data acquisition and reliable, strong real-time property. Through the test data of Matlab wavelet filter, with a white noise filter in addition to verify the effectiveness of filtering algorithm.%在火炮调炮速度测量中,现有设备只能实现平均速度的测量,且体积较大、安装复杂、连线繁多、操作技术要求较高；针对上述问题,基于高精度角速度传感器和虚拟仪器技术,开发了便携式火炮调炮速度实时测量系统；介绍了系统的硬件组成和软件设计流程；通过转台在不同角速度下的测试实验,验证了该系统工作稳定、数据采集可靠,实时性强；通过Matlab对测试数据进行小波滤波处理,较好地滤除了白噪声,验证了滤波算法的有效性.
