基于物联网的RFID室内定位技术
基于物联网的RFID室内定位技术(论文10000字)
摘要:近年来,由于计算机行业的发展,在通信技术方面,尤其是无线通信技术得到了飞速的发展。物联网是新的一代信息技术的重要组成部分,射频(RF)技术在此领域有着非常广泛的应用。其中就包括了定位技术。提到定位技术首先想到的是GPS、北斗等等,这些都是对室外环境的定位,并且也都已经成熟广泛的应用在军事和民用领域。但是,如果环境到了室内,到了地下这些卫星定位系统将不再使用。此外对于商业用途中,成本是排在第一位的,所以室内定位技术得到了人们的关注。RFID室内定位拥有着高效的资源利用率、稳定的性能、低廉的价格受到研究者们的青睐。本文也将对RFID室内定位算法进行深入的研究。对现有的算法作了系统的介绍,同时做出了改进。基于LANDMARC算法,提出了加入修正因子去除环境影响的定位法;针对VIRE算法不能很好的解决边缘定位精度,提出了在边缘引入虚拟参考标签的改善。最后通过仿真实验比较,分析改进算法的性能。

RFID indoor localization based on Internet of things
Abstract: In recent years, due to the development of computer industry, the wireless of communication technology has been developed rapidly. The Internet of things is an important part of the new generation of information technology, and RF technology is widely used in this area. This includes positioning technology. Mentioned positioning, the first things that comes to mind is the GPS, compass and so on. these are outdoor environment location technology, and also have been used in military and civil fields widely. However, for the indoor environment , these technology will no longer be fit for the positioning. in addition to the commercial use , cost is the most important thing. So the indoor positioning technology has aroused people’s attention. RFID indoor positioning with its efficient resource utilization, stable performance and low price is favored by the researchers. This paper will also study the RFID indoor positioning algorithm. We will introduce the present algorithm and make some improvements. Based on the LANDMARC algorithm, this paper will add correction factors to remove the effects of the environment. Because the algorithm of VIRE is not very good to solve the edge positioning, this paper presents a new algorithm that introducing virtual reference tags on the edge. Finally, through the simulation experiment and comparison ,we will analyze the performance of the improved algorithm.
Keywords: RFID;LANDMARC;correction value;VIRE;virtual reference tag
