The continuous innovation and application of the Internet of Things technology has played an important role in promoting the increasingly intelligent parking management system, mainly in the following aspects：
1、Effective utilization of parking resources to improve urban trunk road traffic
By sharing information with each parking lot through the Internet, and in the city trunk road information display screen to provide owners with real-time use of parking spaces around, to help owners make the fastest and most correct choice. The application of this technology helps to alleviate urban traffic congestion, reduce ineffective traffic flow, reduce vehicle exhaust emissions and noise, significantly improve the utilization of existing parking spaces, thereby improving urban traffic efficiency, and achieve green energy conservation and environmental protection purposes.
2、Realization of no parking access Park
Through the application of ETC or RFID technology, the vehicle can stop at the entrance and exit of parking lot or high-speed entrance and exit. Generally speaking, the total time between the two processes is about 30 seconds to 1 minute. With the help of the Internet of Things, the shortest time can be reduced to less than 10 seconds. In contrast, the total time is shorter, which can further promote the rapid entry and exit of vehicles and ensure the smooth flow of vehicles in and out of the entrance.
3、Direct the owner to stop / find the car quickly.
The use of parking space guidance technology is an effective application of the parking lot management system to the Internet of Things technology. Through the use of ultrasonic or video detection technology, the vehicle can be guided to achieve rapid parking. After entering the parking lot, the vehicle can easily find parking space through the parking space guidance screen above the lane and the parking space indicator above the parking space. Quick parking avoids the vexation and inconvenience of looking for empty parking space after vehicles enter the parking lot, avoids the occurrence of traffic jam in the parking lot, makes the whole parking lot more orderly and worries the parking lot managers.
Reverse car-hunting system through the main intersection in the parking lot to set up a car-hunting terminal (car-hunting machine), the owner of the car in the input of relevant information after the system shows the vehicle parking position and the fastest car-hunting route, to help owners quickly find the vehicle. The application of this system helps the car owner to find the car quickly, saves trouble, and has more obvious advantages in large parking lot.
