摘要
-本研究旨在设计和开发基于rssi距离参数的Wi-Fi跟踪系统,用于室内环境下的人群监控应用。该系统由三个主要部分组成,即1)一个运行在Raspberry-pi Zero W上的嵌入式节点,2)一个实时定位算法,以及3)一个带有在线仪表板的服务器系统。嵌入式节点扫描并收集wi - fi连接的智能手机的相关信息,如MAC数据、RSSI、时间戳等。然后将这些数据传输到服务器系统,只要启用Wi-Fi,定位算法就会被动地确定设备的位置。提到的设备是智能手机,平板电脑,笔记本电脑,而使用的算法是一个非线性系统与拉文伯格-马夸特和Unscented卡尔曼滤波器(UKF)。服务器和在线仪表板(基于web的应用程序)具有显示和记录设备本地化结果、设置参数和可视化分析数据三个功能。节点硬件的设计是为了最小的尺寸和便携性,导致消费电子产品的前景。本研究进行了系统演示,以验证其功能和性能。
A Consumer Product of Wi-Fi Tracker System using RSSI-based Distance for Indoor Crowd Monitoring
—This study aims to design and develop Wi-Fi tracker system that utilizes RSSI-based distance parameters for crowd-monitoring applications in indoor settings. The system consists of three main components, namely 1) an embedded node that runs on Raspberry-pi Zero W, 2) a real-time localization algorithm, and 3) a server system with an online dashboard. The embedded node scans and collects relevant information from Wi-Fi-connected smartphones, such as MAC data, RSSI, timestamps, etc. These data are then transmitted to the server system, where the localization algorithm passively determines the location of devices as long as Wi-Fi is enabled. The mentioned devices are smartphones, tablets, laptops, while the algorithm used is a Non-Linear System with Lavenberg–Marquart and Unscented Kalman Filter (UKF). The server and online dashboard (web-based application) have three functions, including displaying and recording device localization results, setting parameters, and visualizing analyzed data. The node hardware was designed for minimum size and portability, resulting in a consumer electronics product outlook. The system demonstration in this study was conducted to validate its functionality and performance.
