摘要: 针对传统火箭弹采集手段不能满足实时数据采集与实现智能化的迫切需求，提出了一种基于MEMS传感器的数据采集技术，对飞行中的速度与高度进行实时采集与应用。将数据采集系统的原理进行分析，在不影响射击精度的前提下，通过主程序软件循环实现实时数据采集，并且设计箱体结构提高抗过载性能，具有重量轻、方便改造等优点。实验数据表明：该设计的高度误差不超过0.5 m，低速时的空速误差在0.5 m/s，高速时的空速误差在3 m/s以内，为装备实现智能化提供了可能。

Abstract: Aiming at the urgent need for real-time data acquisition and intelligentization which cannot be met by traditional rocket acquisition methods, a MEMS sensor-based data acquisition technology is proposed for real-time acquisition and application of speed and altitude in flight. The principle of the data acquisition system is analyzed. On the premise of not affecting the shooting accuracy, real-time data acquisition is realized through the main program software cycle, and the box structure is designed to improve the anti-overload performance, which has the advantages of light weight and convenient transformation. Experimental data show that the height error of the design is less than 0.5 m, the airspeed error at low speed is 0.5 m/s, and the airspeed error at high speed is less than 3 m/s, which provides the possibility for intelligent equipment.
