【摘要】 在铁路勘测设计的线路调查作业中,线路人员须完成大量的野外调查和资料搜集工作。传统的调查方法须借助纸质图纸在野外实地调查、记录数据,然后进行内业数据处理。为提升线调的整体作业效率,将线路计算融入"铁路线路外业调查系统",利用移动GIS技术、卫星定位技术、嵌入式空间数据库技术和语音识别等技术,研发基于Android智能移动终端的集数据采集、分析与存储、线路计算、定位导航和影像资料记录等功能为一体的铁路勘测外业线路调查系统,使其不仅具有一般线调作业的可视化记录功能,而且还使系统具有线路计算和线路导航的功能。更多还原

【Abstract】 In field reconnaissance for a railway design,it is cumbersome for an engineer to finish the field investigation and data collection.In the traditional method,data are always recorded on the paper,and then data processing must be done in an office.In order to improve the overall working efficiency of the field data survey,the calculation on railway alignment is integrated into the "Railway Field Data Survey System",and the function of which is further extended by using mobile GIS technology,satellite positioning technology,embedded spatial database technology and speech recognition technology.The system includes field data collection,analysis and storage,alignment calculation,image record,and locating and navigating a railway based on an Android intelligent mobile terminal.It not only has the visual recording function,but also makes the system have the functions of calculation and navigation.更多还原
