Z igB ee 定位技术在珍贵物品监测中的应用

摘要

随着定位服务的兴起，越来越多的人和公司注重对其所拥有的珍贵物品的管理与保护，通过对其位置的确定达到管理的目的。目前主要的定位方式是利用全球卫星导航系统（ GNSS）。但是许多所要定位的珍贵物品储存于室内，而室内很难接收到卫影信号，所以无法对其进行准确定位。 ZigBee室内定位技术作为目前一种新兴的短距离无线数据网络通信技术，具有低功耗、低成本、低速、高容量、高安全性、高可靠性和短时延等特点非常适合对室内珍贵物品定位。在ZigBee室内定位技术的众多定位算法中RSSI测量技术现代化无线模块已经具有对RSSI的测量功能，不需要额外硬件支持，同时误码率可以被用来估计信号衰减。同时大多数珍贵物品的所存储房间大多室内结构简单，环境因素对其影响较大，信号干扰影响基本很小。所以利用ZigBee定位算法中RS-SI测量技术对室内存放的珍贵物品进行定位是可行的。%With the rise of location -based services , more and more people and companies owned by its focus on the management and protection of valuables , by determining its position to achieve the purpose of management .The main way is to use a global positioning satellite navigation system (GNSS) technology.But many want to locate the valuables stored in the room .Satellite positioning technol-ogy is difficult because of the indoor signal is received so it cannot be accurately positioned .ZigBee indoor positioning technology as currently emerging as a short -range wireless data network communication technology , with low power consumption , low cost, low-speed, high-capacity, high security, high reliability and low latency characteristics are very suitable for indoor precious items posi -tioning.Among the localization algorithm ZigBee indoor positioning technology in modern wireless module RSSI measurement technolo -gy already has a pair of RSSI measurements , no additional hardware support , while the error rate can be used to estimate the signal at-tenuation.At the same time the most precious items stored in a room of mostly simple interior structure , its greater environmental fac-tors, interference signals and basic small .So take advantage of ZigBee positioning algorithm RSSI measurement techniques are valua -ble items were stored indoors is feasible .
