【摘要】 为解决铁路应急管理中地理位置信息的不兼容,实现对事故地点的定位与导航,研究了一维坐标系向二维坐标系的转换算法,阐述了里程点坐标换算的计算方法和实现过程,在此基础上,设计了一套基于移动终端的铁路工务应急定位与导航服务系统,借助百度地图接口,系统以Java作为主要开发语言,选用Android Studio作为集成开发环境,以京沪线部分数据为例,按功能设计进行开发,实现了定位与导航。对于应急管理中救援,具有重要意义。更多还原

【Abstract】 In order to solve the incompatibility of geo-location information in railway emergency management and implement the positioning and navigation of the accident site, this paper studied the conversion algorithm of onedimensional coordinate system to two-dimensional coordinate system, and expounded the calculation method of coordinate conversion point mileage and the implementation process. On the basis of this, the paper designed a set of positioning and navigation service system for emergency management of railway permanent way based on mobile terminal. With the help of Baidu map interface, the system took Java as an important development language, selected Android Studio as an integrated development environment, took some data of Beijing Shanghai Line as an example, developed by functional design, and implemented positioning and navigation. It is of great significance to rescue in emergency management.更多还原
