【摘要】：隨著我國智慧城市的建設,無線城市的發(fā)展變得更快,現如今WIFI已經在很多地方得到了覆蓋,像酒店、飯店、賓館、電影院、超市等,WIFI變得越來越重要,人們的生活中已經不能離開這個新的網民的“寵兒”。隨著人們的生活習慣的改變,到任何一個地方首先會考慮是否有WIFI提供,從網上訂酒店、賓館我們會首先選擇有WIFI的,無形中我們已經離不開這個網絡了。定位對很多人來說都不陌生,我們的手機有定位功能,GPS導航有定位功能,但是不知道大家注意到沒有,GPS的使用也是有限的,只能針對當前主要的一些道路、建筑物和名勝進行一些導航和定位,但其對建筑物內部卻不能實行定位功能。但實際上我們對于這種細節(jié)性的定位功能我們的需求也很大,比如產房嬰兒的看護、監(jiān)獄犯人的看守、重癥病人的跟蹤等都需要我們的區(qū)域性定位功能。由于GPS只能對一些早期建筑設施、道路和進入系統(tǒng)的道路等進行定位,其耗電量也較高,無法通過GPS的使用實現局域性定位。如何利用現有的WIFI網絡實現對監(jiān)控對象在樓宇或建筑物內定位是當前我們所關注的熱點。通過現在區(qū)域性的WIFI能夠提高監(jiān)控對象的定位準確度,能夠對相關的對象進行跟蹤,對于有些監(jiān)控對象可以實現具有針對性的救援,對于整個社會的發(fā)展意義重大。本課題研發(fā)基于WIFI的手機定位系統(tǒng),包含了三個子系統(tǒng)：移動客戶端軟件、AP接入點和服務器端軟件三部分。通過前期對特定區(qū)域的信號采集、地址劃分和特征點標注,系統(tǒng)能夠借助最近鄰匹配算法或三邊定位法對監(jiān)控對象進行計算和處理,從而實現對監(jiān)控物體的定位。系統(tǒng)中將三個子系統(tǒng)進行整合最終形成一個整體,通過移動客戶端調用Google提供的Map API的Geocoder對地址碼實現了信息的解析功能,系統(tǒng)中還采用了一些數據加密的技術來保證系統(tǒng)的運行安全性。最后通過了系統(tǒng)測試,系統(tǒng)運行較好也比較穩(wěn)定可靠。
[Abstract]:With the construction of intelligent cities in our country, wireless cities are developing faster. Nowadays, WIFI has been covered in many places, such as hotels, restaurants, hotels, cinemas, supermarkets and so on. People's lives can no longer leave this new netizen's "darling". With the change of people's living habits, the first thing to consider is whether WIFI is available anywhere. From online hotel booking, we will choose WIFI first, and we can't get away from this network. Positioning is no stranger to many people. Our mobile phones have positioning functions, GPS navigation and positioning, but we do not know that the use of GPS without attention is also limited, and can only be directed at some of the main roads at present. Buildings and places of interest carry out some navigation and positioning, but they can not be used to locate the interior of buildings. But in fact, we also need this kind of detailed location function, such as the care of babies in labor room, the guard of prison inmates, the tracking of critical patients, etc., all of which need our regional location function. Because GPS can only locate some early building facilities, roads and roads entering the system, its power consumption is also relatively high, so it is impossible to use GPS to realize local positioning. How to use the existing WIFI network to locate monitoring objects in buildings or buildings is a hot topic. Now the regional WIFI can improve the positioning accuracy of the monitoring objects, can track the related objects, can achieve targeted rescue for some monitoring objects, and has great significance for the development of the whole society. This paper develops a mobile phone location system based on WIFI, which includes three subsystems: mobile client software AP access point and server software. Through the signal collection, address division and feature point annotation in the early stage, the system can calculate and process the monitoring object with the help of nearest neighbor matching algorithm or trilateral location method, so as to realize the location of the monitoring object. In the system, the three subsystems are integrated into a whole, and the address code can be parsed by the mobile client by calling the Geocoder of Map API provided by Google. Some data encryption techniques are also used in the system to ensure the security of the system. Finally, through the system test, the system runs better and more stable and reliable.
