FAST健康监测数据采集系统开发研究

Exploitation and research of data acquisition system of health monitoring system for FAST

摘要:

对500m口径大射电望远镜(Five-hundred-meter Aperture Spherical Telescope,简称FAST)健康监测系统基础组成部分—FAST健康监测数据采集系统进行开发研究.分析了FAST传感器选型影响因素,结合传感器自身适用标准进行具体选型,完成了基于所选传感器的硬件系统设计,运用Labview平台开发了与FAST监测系统相适应的采集软件系统,形成一套完整的基于虚拟仪器技术的FAST健康监测数据采集系统.FAST30m模型试验是FAST建设过程中的关键步骤,通过在模型试验中的成功应用,表明该系统可为将来FAST健康监测系统的完善提供重要支撑条件.

Abstract:

As a basic part of the health monitoring system of five-hundred-meter aperture spherical telescope(FAST),the data acquisition system was researched in the paper.The sensors used for FAST were chosen considering the antologous characters of the sensors,and a;ardware system was designed based on the chosen sensors.A software system for FAST was developed using the Labview software,so a data acquisition system based on virtual instrument technology was established.Successfully application of the data acquisition system during the experiment on the FAST 30 m-model,which is an important step of FAST,affirms its support for the health monitoring system of FAST.
