Design Of Intelligent Parking Management System Based On Internet Of Things

With the improvement of people’s life quality and the rapid development of automobile consumption market,the problem of urban parking is becoming more and more serious.In addition to the shortage of supporting parking spaces,the traditional parking management mode is not open and transparent,so this makes the driver to obtain parking space information be very difficult and limited parking spaces are underutilized,it is one of the reasons to result the urban parking problem.In order to improve the utilization rate of parking spaces,this thesis designs an intelligent parking space management system based on the Internet of Things.The traditional wireless communication technology is used to collect the parking space information in the parking lot,and the parking space data is collected and provided to the Web service through internet-related development technology.According to the analysis of system requirements,this thesis uses ZigBee technology to realize wireless communication between parking spaces in the parking lot,and the CC2530 is used as the main node control chip to realize the development of node self-organizing network and business functions based on Z-stack protocol stack.And then the parking space information is collected through HC-SR04 ultrasonic sensor to adjust the installation position of different parking spaces.The parking controller connected to the public network is designed in the system to realize communication between the ZigBee network and the Internet server.In order to drive high concurrency problems caused by the simultaneous access between a large number of parking lot networks and users,the system server adopts a service-oriented distributed architecture based on Dubbo and Zookeeper.And the Tomcat is used as the Web application server to load balancing through Nginx.In order to improve development efficiency and system performance,ActiveMQ,Solr,Spring,Mybatis and other open source frameworks are used in this thesis.According to the requirements,designed and compiled the HTML,CSS,JS and bootstrap responsive front-end page for the car owners and administrators.Finally,according to the system design,the simulation test environment has built.And the system hardware and software are tested separately,including sensor measurement accuracy,self-healing of ZigBee network,and realization of various core functions of the system.The test results show that the system can running normally,stable and reliable,and realizes the functions of inquiry,reservation,parking and billing of the parking space.ZigBee technology is used to this system and make this system has strong adaptability,low cost and low power consumption features.It not only eliminates the complicated wiring cost in the parking lot,but also brings great convenience to the parking node deployment.The server-side based service-oriented distributed design greatly improves the overall performance,and the system has strong capacity expansion.Therefore,the design has certain practical and reference value.
