摘要
小型快速绝对重力仪采用经典的自由落体测量原理,要求能对获得的时间距离信息进行快速可靠的采集和分析.本文在小型快速绝对重力仪设计结构基础之上,设计了一种数据采集、分析软件,旨在提供图形化界面,实现数据获取分析的可视化管理.基于Labwindows/CVI软件开发平台提供的多线程机制,完成了对绝对重力仪的控制、数据采集、实时数据处理、分析和结果显示等功能.与FG5自带软件对比表明,该系统可视性好、实时性强和可靠性高.
Using the classic free-fall methods,the small-sized gravimeter is required to collect and analyze time and distance pairs fast and reliably.This article presents the design of the data collection and analysis software,based on pre-existing small-sized gravimeter hardwares,which aims to provide a graphical interface for users to visually manage the data.Based on multithreading technology of Labwindows/CVI,a software of system control,data acquisition and processing,dynamic analysis results displaying for this instrument is designed.The results by comparing with FG5’s software,indicate that,the software is of high visualization,high response speed and high reliability.
