【摘要】：人们已经进入移动互联网时代,日常生活已和各种移动智能终端息息相关,而其中基于位置的服务LBS(Location-Based Services)被称为移动互联网的基石,其被广泛结合于各行各业。LBS与商业促销、实时物流追踪、灾难救援、生活服务等的密切融合,大大的改变了人们的生活方式。本文首先对LBS的研究背景、意义进行了分析,介绍了其框架以及世界范围内的发展历程。并在此基础上,分析设计了基于LBS的智能服务系统,区别以往传统的定时刻闹钟,该系统以定地点操作为切入点,拥有智能定点闹钟、智能定点免打扰、智能定点通讯三个核心功能。并针对LBS应用的核心模块,即定位模块,提出了一种基站小区序列结合GPS的节能定位算法,该算法会预先存储用户历史经过的路径,包括GPS定位坐标点、定位时刻、基站小区序列等信息,当再次经过该路径时,以基站小区序列为检索索引,查询事先存储在数据库中的信息,若有匹配则取出历史定位信息,并根据此信息利用时间相关性对用户现在的定位信息进行估算,不再需要重复用GPS定位,由于基站定位的能耗较低,GPS定位的精度较高,两者结合即可达到节能低耗的目的。并依据此定位算法实现了定位模块,在此基础上实现了本文设计的智能服务系统。最后对该系统进行了测试,其中重点测试了定位模块,并对实验结果进行分析,证明该算法的可行性以及本系统在智能服务方面的应用价值。
[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.
