【摘要】：随着当今城市化建设的快速发展,城市汽车保有量的爆发式增长,使得城市道路路网建设日趋复杂,城市交通状况与出行矛盾日益突出。班车作为企业为员工提供通勤便利的手段被广大企业所采用,也能进一步有效缓解公共交通的压力。与此同时,随着当前移动互联网技术的兴起以及各种智能终端的迅猛发展,员工对班车位置信息的需求越来越迫切。本文设计实现的GPS掌上班车定位系统,从实际需求出发,通在Android平台上通过与后台服务器的交互,可以实时查询指定班车的位置,获取班车运行过程中的经度、纬度以及下一站点的相关参数。相关的用户管理、站点存储、班车实时经纬度位置、站点计算等运算功能在后台服务器上实现,客户端上主要实现展示与交互功能,所有的信息都有服务器通过专用的协议发送至客户端。在客户端上用户可以选择站点模式和地图模式来显示班车当前运行中的实时位置,站点模式会列出班车经过的所有站点,用一个特定的颜色标记站点,并提前给出到站提醒,让用户节省候车时间,方便用户出行,有较强的实用性。本文所使用的关键技术描述主要有GPS技术、Android开发技术以及移动GIS技术等。系统需求来源于已经装备GPS位置上报系统的班车客户,系统的总体架构采用C/S架构。本文对系统使用的经纬度到距离的转化算法、地图偏移量算法以及地图匹配算法等进行了简要的研究,同时,对整个系统的功能模块的实现方法和过程进行了详细的说明。
[Abstract]:With the rapid development of urbanization and the explosive growth of urban car ownership, the construction of urban road network is becoming more and more complex. The contradiction between urban transportation and travel is becoming more and more prominent. As a means of providing commuting convenience for employees, shuttle bus is adopted by the majority of enterprises, which can further effectively relieve the pressure of public transport. At the same time. With the rise of mobile Internet technology and the rapid development of various intelligent terminals, the demand for location information of shuttle bus is becoming more and more urgent. This paper designs and implements the GPS handheld bus location system. Based on the actual requirements, through the interaction with the background server on the Android platform, the location of the designated bus can be queried in real time, and the longitude in the running process of the bus can be obtained. Latitude and related parameters of the next site. Related user management, site storage, bus real-time longitude and latitude location, site calculation and other computing functions are implemented on the background server. Display and interactive functions are mainly implemented on the client side. All information is sent by the server to the client via a dedicated protocol. On the client side, the user can choose site mode and map mode to display the real-time location of the bus in current operation. Site mode will list all the stations that the bus passes by, mark the site with a specific color, and give a warning in advance, so that users can save waiting time and make it convenient for users to travel. The key techniques used in this paper are mainly GPS technology. Android development technology and mobile GIS technology. The system requirements come from the bus customers who have equipped the GPS location reporting system. The overall architecture of the system is based on C / S architecture. In this paper, the conversion algorithm of longitude and latitude to distance, map offset algorithm and map matching algorithm are briefly studied. The realization method and process of the function module of the whole system are explained in detail.
