Design Of Intelligent Parking Guidance System

With people's lifestyles gradually become more modern,driving has become a popular trend,leading to the rapid growth in the number of cars," fewer parking spaces,difficult to find parking spaces,difficult to find cars" and other issues are increasingly serious.In the traditional parking system,users need to reach the destined parking lot before they can gain information on the number of parking spaces.If you enter a large parking lot during the peak period,due to the large venue,it might be impossible to visually observe which parking spaces are free,thus making it tough to reach the parking spaces quickly,which results in not only wasting a lot of time for users in the parking and searching process,but also intensifying the congestion.While proposed intelligent parking guidance system can make parking management more efficient and make the city's traffic pressure effectively relieved.The paper designs an intelligent parking guidance system.In this system,there is a parking space detection hardware platform,and the user can remotely get the number of parking space in the destined parking lot through the mobile phone App.Apart from that,the proposed platform can improve the utilization rate of parking spaces and solve the problems of parking and car search.The system is mainly divided into four parts:1.Through the application of Dijkstra's algorithm and combined with the factors involved in the parking process in the development of the App program,the system provides users with the best parking space,the shortest path to the best parking space and the reverse search.2.Based on the shortest path calculated by Dijkstra's algorithm and combined with the data information in the database,this system obtains all the nodes that the path pass through,and the uses the Classes and Methods provided by the Android language to draw the shortest path guidance from the source node to the parking lot on the App parking information interface.3.A monitoring platform is deployed for each parking space.The parking status information is cored on the STM32 system board and is transmitted through the infrared detection module and the Wi-Fi module.Whether the parking space has vehicle parking information is determined by the infrared detection module,and then the information is uploaded to the server via the Wi-Fi module for background processing.4.The system server is composed of Java Web technology and Tomcat.It uses JSON data format and HTTP communication protocol to implement network data communication with the hardware platform and smart parking App.
