Problems solved by technology

[0007] The application of the above scenarios cannot be used in other scenarios. At the same time, even the existing solutions cannot fully meet the needs of safe and efficient management, such as license plate recognition, which cannot solve the problem of license plate vehicles. ; GPS in the city is limited by high-rise buildings, etc., and cannot accurately locate. Therefore, a new urban intelligent vehicle management system is needed to meet the needs of the market

Embodiment 1

[0054] Embodiment one, a kind of urban vehicle management method based on UWB technology provided by the present invention comprises:

[0055] Such as figure 1 As shown: a positioning base station group is set in the target area of ​​the city, and the positioning base station group includes a plurality of UWB positioning base stations arranged at intervals in the target area, wherein the target area is an indoor parking lot, an open-air parking lot, an urban road or On-street parking areas;

[0056] When the target vehicle carrying the positioning tag enters the target area, the positioning base station group receives the positioning frame sent by the positioning tag, thereby obtaining positioning data;

[0057] It can be understood that the positioning tag is also a UWB tag, which interacts with the UWB positioning base station through UWB technology, and sends a positioning frame to enable the system to locate the positioning tag. Since the positioning tag is installed on t...

Embodiment 2

[0061] Embodiment 2, the positioning method of the present invention adopts a positioning method based on TDOA (Time Difference of Arrival), which requires that the time of UWB positioning base stations must be highly consistent, and the accuracy of time synchronization between base stations determines the positioning accuracy, and usually time synchronization needs to reach nanoseconds level. In order to ensure the time synchronization of the base station time, it is necessary to adopt the method of time synchronization frame.

[0062] Therefore, the method also includes a positioning data calibration step;

[0063] The positioning base station group includes at least one primary base station and at least one secondary base station, wherein the primary base station and the secondary base station are both UWB positioning base stations in the positioning base station group, and the time when multiple secondary base stations receive the primary base station After synchronizing ...

Abstract

The invention provides a city vehicle management method based on a UWB technology. The method comprises the following steps: setting a positioning base station group in an object area of a city, wherein the positioning base station group comprises a plurality of UWB positioning base stations distributed in the object area at intervals, the object area is an indoor parking lot, an open parking lot, and a city road or roadside parking area; when an object vehicle carrying a positioning label enters the object area, receiving positioning frames sent by the positioning label by the positioning base station group so as to obtain positioning data; and uploading the positioning data to a background server by the positioning base station group so as to enable the background server to determine the position of the object vehicle according to the positioning data and the positions of the UWB positioning base stations and to manage the object vehicle according to the position of the object vehicle. Further disclosed is a system. The system can be applied to various city application scenes and satisfies demands for various parking charging, vehicle identification and vehicle positioning tracking in city vehicle management.

Description

technical field [0001] The present application relates to the field of intelligent transportation, in particular to a UWB technology-based urban vehicle management method, positioning base station and system. Background technique [0002] At present, there are a variety of vehicle management methods applied to parking lot charges, on-street parking, road inspection, vehicle identification, path identification, location tracking, vehicle anti-theft, etc., and there is no unified standard, and each management party adopts its own independent management method ; [0003] 1. In the parking lot, in terms of vehicle traffic, there are manual charging by card issuance, license plate recognition, 5.8G ETC automatic charging, etc.; [0004] 2. For on-street parking, the current method adopts the method of geomagnetic detection and manual payment; [0005] 3. Vehicle identification, at present, most of them use license plate recognition, and there are also radio frequency card ident...
