Description

technical field [0001] The present invention relates to a roadside equipment (RoadSideEquipment, RSE for short) dedicated to parking space management in the field of intelligent transportation and the Internet of Things, in particular to a roadside equipment based on geomagnetic wake-up radar ranging technology and its application method. Background technique [0002] At present, as the number of cars in cities hits new highs, the road resources available for parking are decreasing day by day, and the road conditions are also frequently congested, which has attracted great attention from all walks of life. On the premise of not affecting the normal order of road traffic, using economic levers to flexibly set up roadside parking spaces to alleviate parking difficulties has become an effective means of urban management and control in many places. Since the industry used the on-street parking toll system, it has basically used geomagnetic (short for "earth magnetic field") vehi...

Problems solved by technology

[0003] The technical solution disclosed in the existing invention patent "An Information Processing Method and System for Intelligent Traffic People, Vehicles and Roads Based on Information Fusion" (authorized announcement number: CN 102087786 B) focuses on ETC non-stop electronic toll collection, There are certain business requirements for parking electronic toll collection processing scenarios, especially small-scale high-precision toll processing in static parking environments, integrated low-power design of roadside equipment and vehicle detectors, wide coverage of urban applications and low cost. It is necessary to further improve the architecture design of the video part and radio frequency part of the roadside equipment; the existing invention patent "a roadside device with a solar energy collection mechanism" (authorized announcement number: CN 102881052 B) disclosed The technical solution has the following deficiencies: 1. The vehicle detection method is single, and the processing accuracy is not enough for some business scenarios with interference (such as interference from buried wires under the ground, interference from left and right cars, and subway interference). As a result of missed reading or misreading of vehicle card reading identification, it is urgent to further propose the latest and optimal solution; 2. The vehicle identification method is single, and only the radio frequency vehicle identification solution is disclosed. If unattended roadside parking is promoted in the future, fully automatic For electronic toll collection, it is necessary to add a clear picture of the on-site vehicle containing the complete license plate, which can be used not only for legal evidence collection, but also for license plate recognition to comprehensively improve the accuracy of vehicle recognition; 3. In recent years, mobile phone applications have become popular among the people. APP or WeChat electronic payment is quick and easy. It is the time and the general trend to move the human-machine interface from the traditional roadside equipment to the mobile phone.
