| 摘 要： | WiFi无线技术应用极为广泛,是办公室、餐厅、酒店、商场等公众场合的必备。企业和家庭用户设立了大量的无线热点,增加了WiFi热点管理的难度。该文使用树莓派和esp8266单片机,设计与实现了室内WiFi信号的探测设备。它通过测量信号强度rssi值,计算WiFi热点的距离,然后使用三角定位方法,计算各个WiFi热点的坐标值,使用图形界面显示各个WiFi热点的位置。该设备应用了热门的树莓派主板,使用Python编程,通过树莓派GPIO端口控制传感器和读取数据,加速了设备的开发过程,基本实现室内WiFi信号的探测功能。

| Abstract: | WiFi wireless technology is widely used in offices,restaurants,hotels,shopping malls and other public places.Enterpris?es and home users have set up a large number of wireless hotspots,which increases the difficulty of WiFi hotspot management.In this paper,raspberry pie and esp8266 microcontroller are used to design and realize the indoor WiFi signal detection equipment.It calculates the distance of WiFi hotspots by measuring the RSSI value of signal strength,and then calculates the coordinates of each WiFi by using triangle positioning method,and displays the location of WiFi hotspots using graphical interface.The device uses the popular raspberry pi motherboard and uses python programming,control sensors and read data through raspberry pi GPIO port,ac?celerate the development process of equipment,the detection function of indoor WiFi signal is basically realized. |
