基于多普勒效应的车随人动系统

Cars with People Moving System Based on Doppler Effect

针对传统的射频定位依靠电磁波的反射技术,着重研究了同样基于多普勒效应,提出了把其中一端作为目标物,另一端测量目标物的相对速度、方位和距离等的非回波反射的相对定位的方案,使他们的速度、方位一致,距离不变,并把该解决方案应用到车随人动系统。系统包含人端和车端,其中人端作为目标端,车端作为测量端。整个系统基于STM32控制,包含电源、发射、接收等各个硬件模块和软件模型,以达到车跟随人的目的。并通过试验,验证了系统的可行性和可靠性,可作为实际应用。

Traditional radio positioning techniques rely on the reflection of electromagnetic waves. This research is based on the doppler effect, focusing on non-reflective radio frequency（RF）positioning technology to achieve rela- tive positioning to ensure the same speed, direction and distance. We put one object as target, and the other object as measuring side to measure the speed, direction and distance relative to the target, which applies to cars with peo- ple moving system. The system puts person as target and ear as the measureing side. In order to achieve the pur- pose, the car follows the person, the system based on STM32 control includes power, emission, reception of individu- al hardware modules and software models. The feasi-bility and reliability of the system makes it work properly in practical aoolieation.
