【摘要】：人們已經(jīng)進入移動互聯(lián)網(wǎng)時代,日常生活已和各種移動智能終端息息相關,而其中基于位置的服務LBS(Location-Based Services)被稱為移動互聯(lián)網(wǎng)的基石,其被廣泛結合于各行各業(yè)。LBS與商業(yè)促銷、實時物流追蹤、災難救援、生活服務等的密切融合,大大的改變了人們的生活方式。 本文首先對LBS的研究背景、意義進行了分析,介紹了其框架以及世界范圍內(nèi)的發(fā)展歷程。并在此基礎上,分析設計了基于LBS的智能服務系統(tǒng),區(qū)別以往傳統(tǒng)的定時刻鬧鐘,該系統(tǒng)以定地點操作為切入點,擁有智能定點鬧鐘、智能定點免打擾、智能定點通訊三個核心功能。 并針對LBS應用的核心模塊,即定位模塊,提出了一種基站小區(qū)序列結合GPS的節(jié)能定位算法,該算法會預先存儲用戶歷史經(jīng)過的路徑,包括GPS定位坐標點、定位時刻、基站小區(qū)序列等信息,當再次經(jīng)過該路徑時,以基站小區(qū)序列為檢索索引,查詢事先存儲在數(shù)據(jù)庫中的信息,若有匹配則取出歷史定位信息,并根據(jù)此信息利用時間相關性對用戶現(xiàn)在的定位信息進行估算,不再需要重復用GPS定位,由于基站定位的能耗較低,GPS定位的精度較高,兩者結合即可達到節(jié)能低耗的目的。并依據(jù)此定位算法實現(xiàn)了定位模塊,在此基礎上實現(xiàn)了本文設計的智能服務系統(tǒng)。 最后對該系統(tǒng)進行了測試,其中重點測試了定位模塊,并對實驗結果進行分析,證明該算法的可行性以及本系統(tǒng)在智能服務方面的應用價值。
[Abstract]:People have entered the era of mobile Internet, the daily life has been closely related to various mobile intelligent terminals, and the location-based service LBSnLocation-Based Services is called the cornerstone of mobile Internet, which is widely integrated in all walks of life. LBS and commercial promotion. The close integration of real-time logistics tracking disaster rescue and life service has greatly changed people's way of life. Firstly this paper analyzes the research background and significance of LBS and introduces its framework and the development course of the world. On this basis, the intelligent service system based on LBS is analyzed and designed, which distinguishes the traditional fixed time alarm clock. The system takes the fixed point operation as the starting point, has the intelligent fixed point alarm clock, and the intelligent fixed point alarm clock does not disturb. Three core functions of intelligent fixed-point communication. Aiming at the core module of LBS application, that is, location module, this paper presents an energy-saving location algorithm of base station cell sequence combined with GPS, which can store the path of the user's history in advance. Including GPS positioning coordinate point, positioning time, base station cell sequence and other information. When passing through the path again, the base station cell sequence is used as the retrieval index to query the information stored in the database in advance, and if there is a match, the historical location information is extracted. According to this information, the user's current positioning information is estimated by time correlation, and no longer need to repeat GPS positioning. Because the energy consumption of base station positioning is lower and GPS positioning accuracy is higher, the combination of the two can achieve the purpose of energy saving and low consumption. Based on this algorithm, the location module is implemented, and the intelligent service system designed in this paper is implemented. Finally, the system is tested, in which the localization module is emphatically tested, and the experimental results are analyzed. The feasibility of the algorithm and the application value of the system in intelligent service are proved.
