【摘要】：近年來，人們室內(nèi)活動越來越豐富，在室內(nèi)的時間也越來越多。用戶需要一種精確的室內(nèi)定位服務(wù)并能夠快捷的與鄰近用戶交換信息。如何讓手機(jī)更好的便利人們的生活是本論文的研究目的。本文的主要關(guān)注問題是室內(nèi)環(huán)境下的LBS服務(wù)，首先分析了國內(nèi)外對近距離通信和室內(nèi)定位技術(shù)的研究狀況，然后根據(jù)最新的無線技術(shù)和室內(nèi)定位技術(shù)提出了無線傳輸方案和室內(nèi)定位方案。 本文的主要工作可以分為近距離無線通信和室內(nèi)定位服務(wù)兩個部分： 1）本文介紹了低功耗藍(lán)牙技術(shù)和Wi-Fi技術(shù)，通過結(jié)合這兩種技術(shù)給出了近距離無線通信的設(shè)計方案：先使用低功耗藍(lán)牙建立連接，向?qū)Ψ絺鬏斪约旱腎P地址，然后激活Wi-Fi功能模塊，雙方使用基于Socket的網(wǎng)絡(luò)通信來傳輸數(shù)據(jù)。該方案結(jié)合了低功耗藍(lán)牙技術(shù)和Wi-Fi技術(shù)的優(yōu)點(diǎn)，能夠降低文件傳輸過程的耗電量，并有效的解決了無需通過基礎(chǔ)設(shè)施網(wǎng)絡(luò)接入互聯(lián)網(wǎng)服務(wù)器場景下進(jìn)行文件傳輸?shù)膯栴}，能夠滿足近距離無線傳輸數(shù)據(jù)的需求。 2）本文引進(jìn)了杜克大學(xué)方案中的“路標(biāo)”思想以及路由協(xié)議思想，并使用最新的iBeacon技術(shù)，提出了一種新的室內(nèi)定位的方案：在室內(nèi)環(huán)境中布置支持iBeacon技術(shù)的基站，將iBeacon基站充當(dāng)室內(nèi)環(huán)境中的“無形路標(biāo)”。將室內(nèi)環(huán)境劃分幾個不同的區(qū)域，每一個區(qū)域都由一個iBeacon基站進(jìn)行管理，并且相鄰兩個區(qū)域中的基站之間能夠相互通信。由iBeacon基站向區(qū)域中的用戶提供服務(wù)。該室內(nèi)定位方案可以向用戶提供查詢、導(dǎo)航、發(fā)送位置等服務(wù)，，它具有功耗低、布局方便、成本低廉、定位精度高等特點(diǎn)。
[Abstract]:In recent years, people's indoor activities have become more and more abundant. Users need a precise indoor location service and can quickly exchange information with nearby users. How to make mobile phone more convenient for people's life is the purpose of this paper. The main concern is LBS services in an indoor environment, Firstly, the research status of close distance communication and indoor positioning technology at home and abroad is analyzed, and then the wireless transmission scheme and indoor positioning scheme are put forward according to the latest wireless technology and indoor positioning technology. The main work of this paper can be divided into two parts: close distance wireless communication and indoor positioning service. 1) this paper introduces the low-power Bluetooth technology and Wi-Fi technology. By combining these two technologies, the paper gives the design scheme of the close-range wireless communication: first, using low-power Bluetooth to establish the connection and transmit its own IP address to the other side; Then activate the Wi-Fi function module, both sides use network communication based on Socket to transmit data. This scheme combines the advantages of low-power Bluetooth technology and Wi-Fi technology, and can reduce the power consumption of file transfer process. It can effectively solve the problem of file transmission under the scenario of Internet server without access to Internet server through infrastructure network, and can meet the demand of wireless data transmission in close range. 2) this paper introduces the idea of "signpost" and routing protocol in Duke University's scheme, and puts forward a new indoor positioning scheme by using the latest iBeacon technology: placing the base station supporting iBeacon technology in the indoor environment. The iBeacon base station is used as the "invisible road sign" in the indoor environment. The indoor environment is divided into several different areas, each of which is managed by a iBeacon base station. The iBeacon base station can provide service to the users in the region. The indoor positioning scheme can provide the users with query, navigation, transmission location and other services. It has low power consumption, convenient layout, etc. Low cost, high positioning accuracy and other characteristics.
