基于PDOA的智能定位追踪系统

Intelligent Positioning and Tracking System Based on PDOA

本文基于PDOA架构下的UWB射频基站,驱动移动小车追踪标签的无线定位追踪系统,实现了物品对人的追踪功能。该系统主要以意法半导体STM32芯片为核心处理器,通过与PDOA算法有关的定位技术及测距算法所构成的智能系统,实现对装载基站的小车以及持有标签的用户所在位置进行全方位实时检测,同时获取两者的位置信息,并按固定的路径规划和跟踪方案驱动电机,使小车按照一定的速度对手持标签进行实时追踪。

The system is a UWB RF base station based on PDOA architecture It is a wireless positioning andtrack-ing system that usesthe handheld tag equipped with DW1000 positioning chip and drivethe car to track the handheld tag.realize the function of objects to track.The system is based on STM32 chip as the core processor,through the positioning module and ranging module system related to PDOA algorithm,to realize the real-time detection of the location of the car equipped with base station and the user holding the handheld tag,obtain the relative position of the two,according to the fixed path planning and tracking scheme,then drive the motor to make the trolley track the handheld label in real time according to the set speed.The safe distance between the car and people can be set through the program.When the distance between the car and the label reaches the specified range,the car will au-tomatically stop.
