资料介绍

在某些测试系统中,压电类传感器作为非电量采集设备,采集设备具有较高内阻且受感到的电荷信号很小,电荷容易被后端二次设备的阻抗耗散掉,导致采集精度较差。本文针对上述问题,设计了一款高精度、高稳定性、抗干扰性能强的电荷信号调理器。与传统的电荷转换设备相比,本文设计的电荷信号调理器具有精度高、误差小、体积小等优点,适宜在复杂的机载环境中使用。通过搭建实验环境测试可知本文方法的有效可行,此方法可以推广应用在其它非电量压电传感器数据采集场合。

In some of testing system,as an non-electricity acquisition device,acquisition equipment with high internal resistance and is subject to the charge of am signal is little,charge of the easy back-end secondary equipment impedance wasted,leading to a relatively poor acquisition precision.In order to solve the above problems,this article designed a charge signal conditioning with high precision,high stability and strong anti-interference performance.Compared with the traditional charge signal conversion equipment,the charge signal conditioning in this paper has a high precision,small error and small volume,it is more suitable for the application in the complex airborne environment.Through constructing test environment test sh...
