光学二等水准外业数据采集系统的设计与实现

为了提高光学二等水准测量外业的作业效率、数据准确性，提升外业数据采集的实时性、自动化水平，设计开发一套光学二等水准测量数据采集的在线提交系统。该系统基于Java语言的Spring+SpringMVC+MyBatis （SSM）框架技术，实现Android端手机的外业数据采集实时录入、观测数据本地SQLite数据库的存储以及由无线传输方式保存到云端的MySQL数据库。在精密水准控制测量的外业数据采集中的应用表明，该系统在作业效率、数据存储实时性等方面均可取得良好效果，可满足我国大型铁路、公路和其他各类基础设施建设对精密工程测量的需求，提升测绘技术服务于社会的能力。

esign and Implementation of Second Order Leveling OpticalData Collection

To improve the operating efficiency and data accuracy of the optical second order leveling field as well as the real time and automatic level of field data collection,this paper designs and develops an online submission system for optical second order leveling data collection based on the Java language Spring+ SpringMVC+MyBatis (SSM) framework technology.It designs and implements real time input of field data collection on Android mobile phones,storage of observation data in a local SQLite database,and MySQL saving to the cloud by wireless transmission.Application in the field data acquisition of precision leveling control survey shows that the system achieves good results in operation efficiency and real time data storage that meets the needs for precision engineering survey in Chinas large scale railway,highway and other infrastructure constructions,thus improving the ability of surveying and mapping technology in service to the society.
