Research On Design And Application Algorithm Of Smart Parking System

The parking system is an important auxiliary system for automatic vehicle management and user service in modern parking lots.It generally has functions such as automatic billing and vacant parking spaces,and the intelligent parking systems generally require precise parking space management services such as parking space guidance and vehicle assistance.However,since most parking lots are located underground or indoors,how to solve the issues of indoor communication,positioning are the key to achieve the above services.The existing solutions are mostly implemented by Wi-Fi assisted positioning and camera equipment to monitor the parking space,which has high cost and implementation difficulty.Aiming at this problem,a new type of link layer multi-hop self-organizing network technology is discussed,and by using the intelligent IoT terminal designed based on the technology to optimize the related algorithms of the parking system to achieve efficient communication and precise positioning in the room,so as to complete the design and application of the new smart parking system.1.The overall architecture design of the smart parking system based on the new link layer multi-hop communication technology.The overall architecture of the smart parking system consists of a front-end awareness layer,a network communication layer,a data analysis layer,a cloud service layer,a background management layer,and an application service layer.The new link layer multi-hop communication technology has the characteristics of low latency,high rate,low power consumption and antiinterference,which is suitable for dense networking in complex environments.The smart parking system proposed in this paper will rely on the above technology to ensure stable communication and function realization between modules.For example,the handheld terminal in the smart parking system will perform real-time positioning and command transmission through multi-hop interconnection communication with the parking monitoring terminal disposed in the parking lot,thereby realizing accurate positioning and parking guidance of the indoor parking lot.2.Related algorithm design.For the key functions of the parking system,the relevant indoor positioning algorithm,parking space recognition algorithm,route navigation algorithm,parking space allocation algorithm,etc.are optimized and improved to match the system objectives.An optimized Direct Path(DP)detectionmethod is proposed to improve the DP detection efficiency.Then(Multidirectional transmission time,MTT)method is used to achieve accurate indoor positioning.A vehicle target detection algorithm based on improved YOLO loss function is proposed.The vehicle characteristics are extracted by the deep learning model and the position frame prediction and target classification are carried out.Then the position of the target box and the prior frame are compared to determine the parking space;A time-varying shortest path planning algorithm is proposed.By optimizing the arc propagation time estimation,the Dijkstra algorithm is used to calculate the path,and finally the path navigation is realized;An algorithm based on broadcast technology and balance function is proposed,which combines parking space coordinate information to realize the optimal allocation of parking spaces.3.Implementation and application analysis of smart parking system.Based on the above system architecture and application algorithms,the simulation implementation of the intelligent parking system is realized.The system acquires the vehicle image through the terminal,and then transmits the image to the cloud server through the new link layer multi-hop network,processes the information in the cloud,identifies the parking space vacancy,and sends the result to the background management system,and finally presented on the user's handheld terminal.Users can use the handheld terminal to select functions and experience automated parking and car-seeking services.A more efficient and accurate parking management service system is realized through system architecture design and function optimization based on various optimization algorithms.The system enriches the application range of the new link layer multi-hop communication technology to a certain extent,and proposes an innovative solution to the problems of parking space guidance and vehicle assistance in the intelligent parking system,which has strong practical significance.
