Intelligent Parking Space Detection And Guidance System Design And Implementation

With the development of social economy,more and more families have cars,and people use cars to travel more and more frequently,but at the same time,some problems in the process of parking also follow.The traditional parking lot has the problems of inconvenient information acquisition,inconvenient management,difficult parking and difficult vehicle search.In order to solve the above problems and improve the efficiency of parking and vehicle collection,this paper investigates and studies the current large parking lot,designs a parking space detection terminal from the actual parking pain point,studies the parking space guidance,and designs the parking lot positioning scheme and path planning scheme,A set of intelligent parking lot management system for administrators and a wechat applet for driver users have also been developed.The main research contents of this paper are as follows:(1)The design of parking space detection terminal is completed.Firstly,based on the use of geomagnetic detection,a method of parking space state detection using three-axis magnetoresistive sensor is proposed,and the ranging of microwave radar sensor module is used for auxiliary judgment.Then the overall hardware design of the terminal and the circuit design of each module are completed;Finally,the embedded software and cloud platform software of the terminal are designed.(2)The parking space guidance subsystem is designed.Wi Fi location fingerprint positioning is used as the indoor positioning method of intelligent parking lot.The collected RSSI value is preprocessed.According to the RSSI signal characteristics of parking lot and AP,the AP location deployment and fingerprint reference point setting in parking lot are designed.In the online positioning stage,WKNN algorithm is used to locate users.The parking lot is modeled,and then the improved Dijkstra algorithm is used to plan the path between users and parking spaces.(3)Completed the development of intelligent parking lot management system and wechat applet.The spring boot and Vue framework are used to complete the construction of the front and rear ends of the management system,and the deployment in the cloud server.The functions of parking space information viewing,equipment management and account management are realized.The background server can also assist the applet in location calculation and path planning.The development of wechat applet allows drivers and users to view the parking space information in the parking lot and guide the parking space through mobile terminals.Finally,this paper tests the functions of the parking space detection terminal,the management system and the wechat applet respectively.The results show that the parking space detection terminal can accurately perceive the parking space status and report it.The management system can facilitate the parking lot administrator to complete the operations of remote viewing the information in the parking lot.The applet can facilitate the parking and pick-up experience of the driver user.The whole system has good reliability and meets the design requirements.
