监狱犯人室内定位算法研究

A Algorithm Research Based On Prison Inmates Indoor Positioning Algorithm

摘要:

室内定位技术因其在搜索、救援和安全方面的良好使用价值,越来越受到人们的关注。本文主要对基于室内监狱犯人的RFID室内定位算法进行研究,主要涉及其工作原理和相关的定位算法,特别是对LANDMARC室内定位算法进行了深入的研究以及改进优化,根据LANDMARC算法的缺点,通过对LANDMARC算法中阅读器的位置分布,参考标签的分布密度以及选取的参考标签数k值的优化改进,得出更优的LANDMARC改进算法,获得更好的定位精度和定位性能。改进的算法通过Matlab7.0模拟,提高监狱犯人室内定位精度,确保监狱的安全,提高效率。

Abstract:

Indoor location technologies are valued for its favorable using in search, rescue and safety. The paper introduced the RFID positioning system used in the management of prison inmates, mainly revolved round its operational principle and relevant subsistent positioning algorithm, a depth study in LANDMARC was carried out. According to the algorithm’s shortcomings, Optimizing and improving in reader’s positional distribution, reference tag’s distribution density and selected the number k of reference tag to get better improving LANDMARC algorithm. The improving algorithm simulated by Matlab7.0, raising the position accuracy of prison inmates indoor, ensuring the safety of the prison, improving the efficiency.
