The invention provides an intelligent networked automobile parking sentry system based on an ultra wide band. Firstly, a parking sentry system architecture integrating a UWB radar system and a vehicle-mounted all-round camera system is provided, the UWB radar system detects suspected intrusion information around a vehicle in an active pulse sending and echo receiving mode, and the vehicle-mounted all-round camera system is usually in a low-power-consumption mode; and after suspected intrusion information sent by the UWB radar system is received, passive awakening is carried out through a bus signal so as to record image information of dangerous things of an intruding vehicle. On the basis of a visual scheme, a UWB radar detection function is fused, the defects of a traditional visual scheme can be effectively overcome, more and more vehicles carry a UWB technology-based digital key system step by step, and only a UWB radar software function needs to be constructed on the basis of a UWB digital key hardware system; therefore, the production and manufacturing cost of the whole vehicle is further reduced, and great practical significance is achieved.
本发明提出一种基于超宽带的智能网联汽车驻车哨兵系统。首先提出一种UWB雷达系统和车载环视摄像头系统融合的驻车哨兵系统架构,UWB雷达系统通过主动脉冲发送和回波接收的方式探测车辆周围的疑似入侵信息,车载环视摄像头系统通常情况下处于低功耗模式,当接收到UWB雷达系统发出的疑似入侵信息后,通过总线信号被动唤醒,用以记录入侵车辆的危险事物的图像信息。本发明在视觉方案的基础上,融合UWB的雷达探测功能,能够有效弥补传统视觉方案的缺陷,且越来越多的车辆逐步搭载基于UWB技术的数字钥匙系统,本发明只需在UWB数字钥匙硬件系统的基础上构建UWB雷达软件功能即可,从而进一步降低整车生产制造成本,具有很大的现实意义。
