Abstract

This study aims to estimate the position of a small robot in both outdoor and indoor environments using a combination of RSSI-to-distance calculation, trilateration, and MQTT protocol for communication between ESP32 stations and the server. RSSI is utilized to approximate the distance between the ESP32 and the beacon, while trilateration is employed to determine the precise position of the beacon. The ratio of the imaginary circles is calculated by various signal measurement techniques, and the MQTT protocol is used to set up communication between ESP32 stations and the server. Once the beacon device is visible to all three ESP32 modules, trilateration takes place, and the position of the BLE beacon is displayed as a web page. The server collects the largest RSSI values from the nearest three ESP32 stations, and trilateration is performed from the distances obtained, with the coordinates being sent to the dashboard for visual representation. This strategy is supported by a GPS in outdoor environments, and indoors when structures allow it. Furthermore, the study includes the implementation of an experimental procedure and findings that involve utilizing ESP32 modules as scanning stations to track a BLE beacon.

使用 ESP32 信标系统和 GPS 的小型机器人 BLE 信标全球跟踪策略

本研究旨在利用 RSSI-距离计算、三坐标法和用于 ESP32 站与服务器之间通信的 MQTT 协议的组合，估算小型机器人在室外和室内环境中的位置。RSSI 用于估算 ESP32 与信标之间的距离，而三坐标法则用于确定信标的精确位置。通过各种信号测量技术计算虚圆的比率，并使用 MQTT 协议在 ESP32 站和服务器之间建立通信。一旦三个 ESP32 模块都能看到信标设备，就会进行三角测量，并以网页形式显示 BLE 信标的位置。服务器从最近的三个 ESP32 站收集最大的 RSSI 值，然后根据获得的距离进行三坐标定位，并将坐标发送到仪表板以进行可视化显示。这一策略在室外环境下由全球定位系统支持，在室内结构允许的情况下由全球定位系统支持。此外，该研究还包括利用 ESP32 模块作为扫描站跟踪 BLE 信标的实验过程和结果。
