基于LabVIEW的高速数据采集系统设计

摘要

针对卫星电推进分系统地面测试设备建设方案，开发了配套的数据采集存储系统，其实质上是一个电推进试验的总控平台。采用LabVIEW语言建立上位机的数据采集，能够在前台监控计算机提供人机界面，实现数据的采集、保存，各种波形显示，监测数据和试验状态，在线判读，报警等功能。实际运行表明，该系统数据采集过程稳定、可靠，达到了设计要求。%According to the electric propulsion subsystems for the building program of satellite ground testing equipments,a kind of supporting data acquisition and preservation system is developed,which is essentially a general control platform of the electric propulsion test. This paper adopts the LabVIEW lan-guage established data acquisition system,the system can provide human-machine interface in the PC monitoring computer,it realize data acquisition and preservation,a variety of waveform display,data and test condition monitoring,online interpretation and alarm functions. The actual running shows that the da-ta acquisition and preservation system is running stable,reliable,and achieved the design requirements.
