设计了基于到达角度法(Angle of Arrival,AOA)的蓝牙定位系统,并搭建了基于CC2652R1蓝牙开发板和STM32单片机的低功耗蓝牙定位系统。现场测试实验结果表明,本系统能够在室内复杂环境下获取亚米级精度的定位信息,精度可达20 cm,适用于电力智慧运维、智慧工厂、商城导引、仓储物流等场景。
Abstract
In the paper,a Bluetooth positioning system based on Angle of Arrival (AOA) method is designed,and build a low-power Bluetooth positioning system based on CC2652R1 Bluetooth development board and STM32 microcontroller.The field test results show that this system can obtain sub-meter accuracy positioning information in indoor complex environment with accuracy up to 20 cm,which is suitable for scenarios such as electric power smart operation and maintenance,smart factory,shopping mall guidance,and warehouse logistics.
