Design Of Wireless Intelligent Parking System Based On CC2530 And ZigBee Technology

As the construction of smart cities continues to deepen,people have more intelligent and efficient requirements for working and living environments.With the accelerating pace of urbanization,the urban population has increased year by year,and the number of motor vehicles has increased dramatically.This has brought great challenges to smart transportation in the construction of smart cities.This challenge is not only reflected in the running of the road,but also in parking.One of the reasons for the difficulty in parking is that the number of vehicles is too large.The corresponding infrastructure such as parking lots cannot be kept up to speed with the increase in the speed of vehicles.On the other hand,the utilization of existing infrastructure resources is low.Existing parking spaces do not have Get full use.In this paper,a wireless intelligent parking system is designed to increase the utilization of parking resources,reduce the congestion around and inside the parking lot,reduce the pressure on the construction of intelligent transportation in the parking sector,and realize an energy-saving,environmentally-friendly and efficient parking environment.As a typical application scenario of the Internet of Things,the wireless intelligent parking lot can use the Internet of Things technology to realize the intelligentization and high efficiency of the parking lot.This article adopts the mainstream chip of the Internet of Things CC2530 produced by Texas Instruments as the basic chip of the sensor node,and the ZigBee protocol of wireless intelligent sensing as the transmission protocol in the wireless network,and combines the relevant on-chip system and hardware and software facilities for system design.The system consists of terminal nodes,coordinator nodes,host computers,electronic display screens,and smart display terminals.The terminal node is used to detect the status of the parking space and provide position information.The ultrasonic sensor's ranging function is used to detect the parking status.The indoor positioning algorithm is used to locate the node position.The parking status information and position information are sent from the terminal node to the coordinator.node.The coordinator node is mainly used to provide routing,aggregate terminal node data information and upload it to the upper computer.The host computer receives the information of the coordinator and sorts it into the database.After the consolidation,the status information of the parking spaces is provided to the external electronic display screen of the parking lot for the display of the remaining parking spaces.On the one hand,it is used by the Internet,and the remaining parking spaces in the nearby parking lot are also called from the Internet.Quantity.The location information is then called by the optimal path algorithm to generate the optimal parking guidance path to send to the user's smart display terminal,helping the owner to quickly and efficiently find the parking space.This system combines actual use scenarios,uses wireless nodes for networking,uses wireless sensory ZigBee protocol for data transmission,and significantly reduces node power consumption and node life through hardware design and dynamic power adjustment;users select idle The parking space can generate an optimal parking guidance path,quickly find a parking space through the parking path,and avoid the disorderly search of the vehicle owner in the parking lot,which saves a lot of time and improves the parking efficiency.
