基于蓝牙RSSI的三角定位测距

Triangulation Ranging Based on Bluetooth RSSI

摘要: 在疫情防控常态下，保持安全距离成为了最重要的社交礼仪，特别是在一些人口比较密集、人流量比较大的场所，这些地方疫情防控比较困难，而且防控所需要的人力资源也会更多，基于公共场所对人群保持社交距离提醒的考虑，本文设计了一种基于蓝牙RSSI的三角定位测距方式。具体是通过蓝牙设备定位结合三角定位测距算法来实现，蓝牙设备功耗低，成本低廉，使用方便，且在众多室内定位技术中，蓝牙具有独特的优势。

Abstract: Under the normal situation of epidemic prevention and control, maintaining security distance has become the most important social etiquette, especially in some places with relatively dense population and large flow of people. These places are more difficult to prevent and control the epidemic, and the human resources required for prevention and control will be more. Based on the consideration of social distancing reminders for people in public places, this paper designs a triangulation ranging method based on Bluetooth RSSI. It is realized by Bluetooth device positioning combined with triangulation ranging algorithm. Bluetooth device has low power consumption, low cost and convenient use, and among many indoor positioning technologies, Bluetooth has unique advantages.
