基于Android系统的重力仪数据采集及计算软件开发

Development of gravity data acquisition and calculation software based on the android platform

针对目前重力测量数据处理软件多是基于Windows系统,而这与携带Android移动设备相比多有不便的问题,该文提出了一种基于Android系统的重力数据采集及计算软件的开发。按照国家重力测量规范,针对CG-5型相对重力仪,设计研发了一款基于Android系统平台的重力数据采集及计算软件,较好地方便了用户野外携带。其具有新建、打开测线、数据采集处理、点之记拍照、导航定位、数据查询、信息标定、CG-5数据文档读取、报表生成等功能。在数据处理模块的传统改正项中,新增了海潮负荷改正和地下水变化改正,减少了误差项。通过将软件用于实地重力测量计算,证实该软件运行流畅、结果正确,提高了相对重力测量内外业一体化效率。

For the current gravity survey data processing software are mostly based on windows system,it is inconvenient for people with computer carrying Android mobile device.Therefor,development of gravity data acquisition and calculation software based on the Android platform was proposed in the paper.In accordance with national gravity measurements standards,design and development of the gravity data acquisition and calculation software based on the Android platform for CG-5type,was more convenient for the field work carried-on.It had a series of function including new,open measuring line,data acquisition and processing,photograph of description of station,navigation,data query,calibration information,CG-5data document reading,report generation,and other functions.Compared with traditional correction data processor module,ocean tide loading corrections and correction of the change of groundwater were added reducing the error terms.In practice,it was confirmed that the software run smoothly,and the result was correct,improving efficiency of the relative gravity measurement the indoor and field.
