Design Of Intelligent Parking Management System Based On NB-IoT

With the acceleration of urbanization in China,the number of citizens' motor vehicles is increasing rapidly,more and more car owners are facing the problem of parking.Therefore,in order to meet the management needs of building a safe and civilized city,this subject takes the ground parking lot in the community or building as the management goal and designs an intelligent parking management system.The system takes the vehicles entering and leaving the residential area or building as the research object,and expects to realize the user's safe,convenient and efficient parking,which has practical significance and application value.According to the needs of modern intelligent parking,an intelligent parking management system based on NB-IoT is designed in this subject,which not only realizes the quick parking of car owners but also ensures the improvement of garage utilization.The system is mainly composed of five parts: parking information acquisition module,information centralized processing module,data transmission module,radio frequency identification module,and user terminal.Firstly,it collects whether there is a car in this parking space by using the wireless vehicle detector module.Then,the collected information is sent to the cloud database through NB-IoT and the parking space information is shown on the APP.Car owners use the RFID card to input information and record parking information when parking,which is convenient for charge management.In terms of software implementation,this system completes the writing of the sensor module,wireless module,and other low-level programs under the Keil development environment of C language program,and integrates and debuts them on the host computer to form a complete intelligent parking management system.Compared with the existing parking management system,this system uses NB-IoT,a transmission module with low power consumption and wide coverage,to transmit the detected vehicle information to the client,where the real-time usage of parking spaces can be displayed.It makes full use of the existing network resources of telecom operators and greatly improves parking efficiency.In addition,based on the designed system,this paper also carries out innovative thinking on the business operation mode of the intelligent parking management system,compares the operation modes of telecom operators and system operators under different business modes,and proposes a new idea of NB-IoT intelligent parking management system,which has certain commercial value.The experimental test shows that the system can effectively manage the parking spaces in the shopping mall or the community,and greatly improve the management level and work efficiency of parking spaces in the garage.
