安卓系统下开发测量程序的应用研究

Application Research on Measuring Program Design Based on the Android System in Mobile Terminals

设计并实现了基于安卓系统移动终端的测量程序,该程序可以在移动终端上实现单一导线、水准路线、交会测量的外业记录与计算功能,不同坐标系下的坐标转换功能,并可以通过蓝牙完成移动设备间、移动设备与计算机间的数据通讯功能。重点讨论了系统设计过程中利用SQLite数据库对外业记录的存储管理过程,最后给出实际外业测量的系统实现示例。结果表明,该系统易于在目前移动终端上运行,减轻测量人员的外业计算量,实现测量外业记录的无纸化。

This paper designs and achieves a measuring program based on the android system in mobile terminals. The data of a single traverse,a single level-line or intersection survey can be recorded and calculated by this program. And different coordinates can be conversed in different coordinate systems in this program. All the data can be transfered between mobile terminals,personal computers via bluetooth. This paper mainly introduces storage and management of records from measurement outside by the SQLite database. Finally,this paper gives some practical applications of this program,which shows that the mobile terminals with this program can ease calculation workload outside and make jobs outside paperless.
