Design And Research Of Parking Lot Management System Based On Internet Of Things

With the increase of the number of urban cars,the difficulty of parking has become a common social problem in the major cities of our country.Parking lot management system is regarded as an important part of intelligent transportation in smart city.The utilization rate of parking spaces can be improved,the utilization of parking facilities can be balanced,the time consumption of users looking for parking spaces can be reduced,and the increasingly serious traffic congestion problem can be alleviated.In view of this,sensor technology and Internet of things technology are comprehensively applied to this paper.An intelligent parking lot management system based on NB-Io T-Zig Bee is designed and implemented.Four parts are included in the design of parking management system based on NB-Io T-Zig Bee: the collection of parking information,the transmission of parking information,the management of parking information and the release of parking information.The work flow of the system is as follows: the parking information is detected by the information collection terminal through the sensor.The parking change information is sent to the Zig Bee coordinator by the CC2530 microprocessor.The information is processed by the coordinator and passed to the NB-Io T wireless transmission module through AT instructions.Then data information is sent to the cloud platform management center by the NB-Io T wireless transmission module.Data information is published to smart terminals via servers by cloud platforms,parking information is updated in real time.The guide electronic screen which updates the parking information in real time is used as the main information carrier,at the same time,parking information is published by APP and WEB on mobile phone,Three information publishing methods used by the parking management system make it easier for users to understand parking space information.The system has been tested and verified by function and performance,and the results show that: The communication state of wireless heterogeneous network based on Zig Bee and NB-Io T is good,the function of parking information collection node is normal.Parking space information can be displayed correctly by WEB management interface and mobile APP.On the basis of the traditional parking lot,A wireless communication method combining Zig Bee with NB-Io T is introduced in this paper.It is not only practical but also beautiful.It meets the development requirements of smart cities。Figure [69] table [11] reference [55]...
