基于 C8051F380的弹丸表面压力数据采集系统

介绍了一种由传感器、信号调理电路、数据采集、存储器及通讯接口等部分组成的微型气压数据采集系统，它能够在不破坏弹体的情况下进行弹丸表面压力的采集，具有体积小、安装方便、能放置到被测体内等特点；以单兵火箭弹为例并进行相关试验；实验结果表明：该系统能够准确有效地进行火箭弹弹体表面压力信号的采集，并且采集数据与理论数据比较吻合。

Design of Projectile Surface Pressure Data Acquisition System Based on C8051F380

This paper introduced a kind of the micro air pressure data acquisition system that include sen-sors,signal conditioning circuit,data acquisition,storage,communication interface and other components. It can collect the projectile pressure on the surface without breaking the projectile.The system has some characteristics,such as small volume,convenient installation,that can be put into the tested body and so on.Taking the individual rocket as an example and some relevant tests were carried out.The result shows that the system can accurately and effectively acquire the rocket projectile surface pressure data when it fly-ing and the acquisition of data is in accordance with the theory data in comparison.
