本发明涉及一种基于UWB最小通讯系统的寻车装置及使用方法，属信息通讯技术领域。The invention relates to a vehicle searching device based on a UWB minimum communication system and a using method, belonging to the technical field of information communication.
背景技术Background technique
UWB：超宽带（Ultra Wide Band，UWB）技术是一种无线载波通信技术。通过两个搭载UWB的设备之间的长距离通讯，进行测距以及方向角的确认来达到在停车场寻车的目的。UWB: Ultra Wide Band (UWB) technology is a wireless carrier communication technology. Through long-distance communication between two UWB-equipped devices, ranging and direction angle confirmation are performed to achieve the purpose of finding a car in the parking lot.
目前基于UWB技术的车辆寻找系统均采用基站加标签方式，该方式就要求停车场地必须事先部署大量UWB基站，才可以完成精确定位。而由于目前车辆大量的增加，对现有停车系统的改造成本较高，导致此技术无法在实际生活场景中应用。摄像头等技术也均需要事先部署设备才可以完成寻车，并且并不能直观的向用户指明方向，仅能提供车位号，用户还是自行去寻找车位号的所在，因此造成当前在停车场，尤其时通讯基站覆盖差的地下停车场内寻车时难度及精度均相对较大，难以有效满足使用的需要。At present, the vehicle finding systems based on UWB technology all use the base station tagging method, which requires that a large number of UWB base stations must be deployed in advance in the parking lot to complete accurate positioning. However, due to the large increase of vehicles at present, the transformation cost of the existing parking system is relatively high, so this technology cannot be applied in real life scenarios. Cameras and other technologies also need to deploy equipment in advance to complete the car search, and can not intuitively indicate the direction to the user, only the parking space number can be provided. The user still finds the location of the parking space number by himself. The difficulty and accuracy of car search in the underground parking lot with poor communication base station coverage are relatively large, and it is difficult to effectively meet the needs of use.
因此针对这一问题，迫切需要开发一种全新的UWB最小通讯系统的寻车装置及使用方法，以满足实际使用的需要。Therefore, in view of this problem, it is urgent to develop a brand-new vehicle-finding device and using method of the UWB minimum communication system to meet the needs of practical use.
