【摘要】：分布嵌入式軟件功能模塊的設計與實現(xiàn)是當前研究熱點,在嵌入式系統(tǒng)中,實時定位的研發(fā)是一類重要的應用。在手機上開發(fā)實時定位軟件,選擇Android這樣的技術框架是必要的。首先,Android集成了地圖模塊和豐富的API,能有效支持嵌入式軟件在分布移動環(huán)境中的定位功能實現(xiàn)；其次,在Android平臺上二次開發(fā)手機定位軟件,一方面降低了開發(fā)難度,另一方面減少了開發(fā)成本。最重要的是Android平臺具備良好的兼容性和可移植性。 與當前主流定位(Google,Yahoo,Virtual Earth)相比,本文的定位技術有以下幾個特點：1)熱點查詢體現(xiàn)了顯著的區(qū)域性；2)根據(jù)定位的已知條件將定位分為反碼,正碼和短信定位三種方式,進一步細化了定位服務；3)在正反碼定位設計的基礎上,提出新的定位方式—短信定位,給出思想,算法和開發(fā)過程,并驗證了結果的可行性；4)區(qū)域公交查詢詳細的路線信息完善了Google全球路線查詢的粗略；5)天氣查詢給出天氣信息,通過結合其它模塊,是用戶出行、旅游的重要參考。論文主要工作包括： 1、對比分析了市場上主流操作系統(tǒng),介紹了Android平臺框架和應用程序開發(fā)流程；比較目前主流數(shù)據(jù)庫和嵌入式數(shù)據(jù)庫,介紹了SQLite數(shù)據(jù)庫的實現(xiàn)機制； 2、根據(jù)定位的條件,將定位分解為反碼,正碼和短信定位。反碼是根據(jù)經(jīng)緯度來定位,主要完成圖標定位,放大、縮小地圖,在衛(wèi)星、街道、交通三種地圖模式之間轉換；正碼根據(jù)具體地址來定位,原理是將地址轉換成地標再定位； 3、在正反碼定位的基礎上,提出了短信定位。短信定位的本質是間接定位,通過短信內容獲取經(jīng)緯度,達到在地圖上定位他人的目的。 4、以定位服務為核心,擴展了路線指南,公交查詢,天氣查詢和熱點查詢等模塊,內容如下： 1)路線指南的趨近提示根據(jù)進出入?yún)^(qū)域范圍給出提示；路徑規(guī)劃實時更新當前位置并繪出路線軌跡；路線選擇根據(jù)用戶選擇給出相關的信息； 2)公交查詢中的車次查詢給出某車次的首末班車發(fā)車時間、起點、終點站和售票信息；站點查詢給出車次經(jīng)過的所有站；換乘查詢在代碼中按照直達、一次、二次換乘的順序設置優(yōu)先級進行查詢； 3)天氣查詢模塊給出當前天氣信息(溫度,濕度,風向)以及未來四天的預測； 4)熱點查詢給出熱點簡介及周邊信息。
[Abstract]:The design and implementation of distributed embedded software function modules is a hot topic at present. In embedded systems, the research and development of real-time positioning is an important application. It is necessary to develop real-time positioning software on mobile phone and choose a technical framework such as Android. First of all, Android integrates map module and rich API, which can effectively support the location function of embedded software in distributed mobile environment. Secondly, the second development of mobile phone location software on Android platform, on the one hand, reduces the development difficulty. On the other hand, it reduces the cost of development. The most important thing is that the Android platform has good compatibility and portability. Compared with the current Google Yahoo Virtual Earth, the location technology of this paper has the following characteristics: 1) the hot spot query embodies a significant regional area 2) according to the known conditions of location, the location is divided into three ways: inverse code, positive code and short message location. On the basis of the design of forward and negative code location, a new location method, short message location, is proposed, and the idea, algorithm and development process are given, and the feasibility of the result is verified. 4) the detailed route information of regional public transport query improves the rough of Google global route query. Weather query gives weather information. By combining other modules, it is an important reference for users to travel and travel. The main work of this paper is as follows: 1. Comparing and analyzing the mainstream operating system in the market, introducing the framework of Android platform and developing process of application program, comparing the current mainstream database with embedded database, The implementation mechanism of SQLite database is introduced. 2. According to the condition of location, the location is decomposed into inverse code, positive code and short message location. The inverse code is located according to latitude and longitude, mainly completes the icon localization, zooms in, reduces the map, in the satellite, the street, the traffic three kinds of map mode conversion, the positive code according to the concrete address localization, the principle is to convert the address to the landmark to locate; 3. On the basis of forward and negative code localization, the short message location is put forward. The essence of short message positioning is indirect positioning. By obtaining latitude and longitude through short message content, we can achieve the purpose of locating others on the map. 4. Taking location service as the core, we have expanded the route guide and public transportation inquiry. The contents of weather query and hot spot query are as follows: 1) the approach hint of route guide is given according to the range of entering and going into the area, the path planning updates the current position in real time and draws the track of the route; Route selection gives the relevant information according to the user's choice; 2) the train number query in the public transportation query gives the departure time, starting point, terminal station and ticket selling information of the first and last train of a certain train; The transfer query is carried out according to the order of direct, first and second transfer in the code. 3) the weather query module gives the current weather information (temperature, humidity, wind direction) and the forecast for the next four days. 4) Hot spot query gives hot spot brief and peripheral information.
