【摘要】：隨著當(dāng)今城市化建設(shè)的快速發(fā)展,城市汽車保有量的爆發(fā)式增長,使得城市道路路網(wǎng)建設(shè)日趨復(fù)雜,城市交通狀況與出行矛盾日益突出。班車作為企業(yè)為員工提供通勤便利的手段被廣大企業(yè)所采用,也能進一步有效緩解公共交通的壓力。與此同時,隨著當(dāng)前移動互聯(lián)網(wǎng)技術(shù)的興起以及各種智能終端的迅猛發(fā)展,員工對班車位置信息的需求越來越迫切。本文設(shè)計實現(xiàn)的GPS掌上班車定位系統(tǒng),從實際需求出發(fā),通在Android平臺上通過與后臺服務(wù)器的交互,可以實時查詢指定班車的位置,獲取班車運行過程中的經(jīng)度、緯度以及下一站點的相關(guān)參數(shù)。相關(guān)的用戶管理、站點存儲、班車實時經(jīng)緯度位置、站點計算等運算功能在后臺服務(wù)器上實現(xiàn),客戶端上主要實現(xiàn)展示與交互功能,所有的信息都有服務(wù)器通過專用的協(xié)議發(fā)送至客戶端。在客戶端上用戶可以選擇站點模式和地圖模式來顯示班車當(dāng)前運行中的實時位置,站點模式會列出班車經(jīng)過的所有站點,用一個特定的顏色標記站點,并提前給出到站提醒,讓用戶節(jié)省候車時間,方便用戶出行,有較強的實用性。本文所使用的關(guān)鍵技術(shù)描述主要有GPS技術(shù)、Android開發(fā)技術(shù)以及移動GIS技術(shù)等。系統(tǒng)需求來源于已經(jīng)裝備GPS位置上報系統(tǒng)的班車客戶,系統(tǒng)的總體架構(gòu)采用C/S架構(gòu)。本文對系統(tǒng)使用的經(jīng)緯度到距離的轉(zhuǎn)化算法、地圖偏移量算法以及地圖匹配算法等進行了簡要的研究,同時,對整個系統(tǒng)的功能模塊的實現(xiàn)方法和過程進行了詳細的說明。
[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.
