Research And Design Of 3D Layered Positioning Of Intelligent Parking Lot Based On RFID

With the improvement of people's living standards and the sharp increase of the number of vehicles,traffic congestion and parking problems become increasingly serious.This paper investigates the parking lot management system at this stage,and finds that most of the systems on the market are still traditional and do not implement intelligent management,resulting in owners unable to understand parking information in advance and quickly reserve parking spaces,and so on.Therefore,the related research topics of intelligent parking lot are put forward.According to the current situation of parking management system,this paper uses RFID-based three-dimensional hierarchical positioning technology to achieve parking information acquisition in the parking lot,and designs an intelligent parking system.The content of this paper mainly includes indoor localization algorithm and parking system design for multi-layer intelligent parking application scenarios.Based on the classical LANDMARC localization algorithm,an iterative algorithm I-LANDMARC in a 3D space model is proposed in this paper,which effectively improves the localization accuracy.Then the multi-layer intelligent parking system and its core modules are analyzed in detail.According to the target requirements of the intelligent parking management system,the overall framework model is studied and designed,and the realization and functional scheme of each module are introduced.Finally,the I-LANDMARC algorithm applied in multi-storey parking lot is modified to make it suitable for the multi-storey parking lot model.The attenuation effect caused by wall occlusion is added to the multi-storey parking lot,and the positioning results are stratified to determine the specific localization of the parking space.Finally,the hierarchical location algorithm applied to multi-storey parking lot is validated and the operation of multi-storey parking lot is simulated and analyzed.
