摘　　要：为促进车辆出入智能化管理技术发展,提出一种基于TDOA、AOA定位算法的车辆出入管理系统。利用RFID技术实时获取车辆的身份信息与位置信息,将测得的各个基站与车辆之间信号传播的时间差与相对角度,代入到TDOA、AOA定位算法以估算出车辆各移动节点的定位坐标,通过节点坐标变化进而判断车辆出入情况,并结合数据传输、自动控制等技术实现动态管理。经模块开发与实验仿真,系统可应用于车辆出入智能判断与管理,为后续研究提供理论基础。In order to promote the development of intelligent management technology for vehicle access,a vehicle access management system based on TDOA and AOA positioning algorithms was proposed.RFID technology was used to obtain vehicle's identity information and location information in real time.The time difference and relative angle of signal propagation between each base station and the vehicle were substituted into TDOA and AOA positioning algorithms to estimate the location coordinates of each mobile node of the vehicle.Through the change of node coordinates,the vehicle entry and exit situation can be judged,and dynamic management of vehicle access can be realized by combining data transmission,automatic control and other technologies.Through the module development and experiment simulation,the proposed system can be applied to the intelligent judgment and management of vehicle access,which provides a theoretical basis for follow-up research.
