| China’s urban parking problems become increasingly serious,parking induction system came into being.However,most of the existing parking guidance systems focus on off-site induction,lack of attention to the induction of specific parking spaces after entering the parking lot,and to obtain real-time information and accuracy is not high.How to provide real-time and reliable information for the driver and the fast parking of the user into the parking lot,and put forward the urban parking guidance system based on the Internet of Things technology.In this paper,the Internet of Things technology as a system support for each driving vehicle is equipped with a unique ID electronic tags,through RFID technology and sensor technology to obtain vehicle-related information,and the use of sensors(ultrasonic detectors)real-time detection of the use of each parking spaces Situation,while the camera and related auxiliary equipment to monitor the situation occurred within the parking lot.Real-time monitoring of vehicle,field and bit information,and lay a solid foundation for the recommendation and optimal route guidance service of follow-up accurate parking spaces.Finally,the system will publish the information in the field LED display,while users can query the entire city through the mobile terminal parking information,and then to achieve the parking lot parking and electronic payment function.In view of the process of parking spaces in the parking lot,the main factors influencing the parking spaces in the parking lot,including the walking distance,driving distance,safety,the duration of the shade and the occupancy of the vehicle on both sides of the parking space,The influence factors are transformed into multiple attribute decision-making problems to determine the decision attribute matrix,and finally the optimal parking position selection model based on ideal solution gray correlation degree is established.And then all the free parking spaces in a parking lot at all times to determine the best parking spaces.Based on the parking route selection route optimization algorithm,the optimal route to the optimal parking spaces is designed and then guided by the voice and LED electronic induction screen Drive into the best parking spaces.The reliability of the scheme is verified by case analysis and hardware and software testing.The system can realize the efficient and safe management of the parking lot,not only improve the parking lot parking space utilization,shorten the user travel time,effectively save energy and improve air pollution,but also indirectly stimulate the rapid development of urban economy. |
