摘　　要：利用声发射传感器对空间碎片的撞击数据进行实时采集监测,用以对航天器在轨安全防护提供预警。该系统基于LabVIEW虚拟仪器技术,采用图形化编程语言实现了高速数据的采集。具有数据采集、实时波形显示、数据存储等功能,编程简捷、精度高、稳定性好,且人机界面友好。Real-time data acquisition system with acoustic emission (AE) sensors could provide early warning to the threat of impact to spacecraft by space debris. In this paper, the design and development of a high-speed data acquisition system with Graph-Language LabVIEW 7 are presented. The system involves real-time waveform display, data acquisition and storage. It is shown that the response is fast, the precision and stability are high, and the interface is friendly.
