航天器空投试验用大容量数据记录器的研究

在航天器空投试验中,数据记录器需要长时间高速采集试验数据,并将试验数据保存起来。记录器还要满足体积小和抗着陆冲击等恶劣环境的要求。文章介绍了数据记录器的特点、主要功能,硬件选型及软件设计等。提供了一种利用嵌入式技术来构成大容量高速率航天器空投试验用数据记录器的方法。

Research of Big Capacitance Data Recorder Used in Air- Drop Experiment

During the process of Air-drop experiment,data recorder needs to collect data for a long time and in high speed,and save data to disk as soon as possible.The recorder should also reach the demands of resisting severe environment like small cubage and landing impact.This dissertation introduces the design of the data recorder,its main function,hardware choosing and software design etc,and provided a way to form a data recorder used in airdrop experiment which has big capacitance and high acquisition speed utilizing embedded technology.
