【摘要】：隨著我國(guó)智慧城市的建設(shè),無(wú)線城市的發(fā)展變得更快,現(xiàn)如今WIFI已經(jīng)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(lái)越重要,人們的生活中已經(jīng)不能離開(kāi)這個(gè)新的網(wǎng)民的“寵兒”。隨著人們的生活習(xí)慣的改變,到任何一個(gè)地方首先會(huì)考慮是否有WIFI提供,從網(wǎng)上訂酒店、賓館我們會(huì)首先選擇有WIFI的,無(wú)形中我們已經(jīng)離不開(kāi)這個(gè)網(wǎng)絡(luò)了。定位對(duì)很多人來(lái)說(shuō)都不陌生,我們的手機(jī)有定位功能,GPS導(dǎo)航有定位功能,但是不知道大家注意到?jīng)]有,GPS的使用也是有限的,只能針對(duì)當(dāng)前主要的一些道路、建筑物和名勝進(jìn)行一些導(dǎo)航和定位,但其對(duì)建筑物內(nèi)部卻不能實(shí)行定位功能。但實(shí)際上我們對(duì)于這種細(xì)節(jié)性的定位功能我們的需求也很大,比如產(chǎn)房嬰兒的看護(hù)、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(duì)一些早期建筑設(shè)施、道路和進(jìn)入系統(tǒng)的道路等進(jìn)行定位,其耗電量也較高,無(wú)法通過(guò)GPS的使用實(shí)現(xiàn)局域性定位。如何利用現(xiàn)有的WIFI網(wǎng)絡(luò)實(shí)現(xiàn)對(duì)監(jiān)控對(duì)象在樓宇或建筑物內(nèi)定位是當(dāng)前我們所關(guān)注的熱點(diǎn)。通過(guò)現(xiàn)在區(qū)域性的WIFI能夠提高監(jiān)控對(duì)象的定位準(zhǔn)確度,能夠?qū)ο嚓P(guān)的對(duì)象進(jìn)行跟蹤,對(duì)于有些監(jiān)控對(duì)象可以實(shí)現(xiàn)具有針對(duì)性的救援,對(duì)于整個(gè)社會(huì)的發(fā)展意義重大。本課題研發(fā)基于WIFI的手機(jī)定位系統(tǒng),包含了三個(gè)子系統(tǒng)：移動(dòng)客戶(hù)端軟件、AP接入點(diǎn)和服務(wù)器端軟件三部分。通過(guò)前期對(duì)特定區(qū)域的信號(hào)采集、地址劃分和特征點(diǎn)標(biāo)注,系統(tǒng)能夠借助最近鄰匹配算法或三邊定位法對(duì)監(jiān)控對(duì)象進(jìn)行計(jì)算和處理,從而實(shí)現(xiàn)對(duì)監(jiān)控物體的定位。系統(tǒng)中將三個(gè)子系統(tǒng)進(jìn)行整合最終形成一個(gè)整體,通過(guò)移動(dòng)客戶(hù)端調(diào)用Google提供的Map API的Geocoder對(duì)地址碼實(shí)現(xiàn)了信息的解析功能,系統(tǒng)中還采用了一些數(shù)據(jù)加密的技術(shù)來(lái)保證系統(tǒng)的運(yùn)行安全性。最后通過(guò)了系統(tǒng)測(cè)試,系統(tǒng)運(yùn)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.
