The smart parking revolution is unfolding globally, with core technologies including integrated applications of video, ultrasound, and wireless geomagnetic parking guidance technology. The integration of these technologies not only significantly improves parking efficiency, but also optimizes the operation management and user experience of parking lots.

Video technology plays an important role in smart parking. The application of high-level videos has enabled the centralized management and operation of on road parking spaces that have been taken over to be intelligent, visual, and scientific. This technology can monitor berths 24/7, effectively resisting environmental disturbances such as rain, fog, and extreme weather. It can also generate complete image evidence based on the vehicle's driving trajectory, automatically recognize the vehicle's parking and driving behavior, license plate number, and generate parking records. By transmitting this information to the parking information service platform, real-time services such as timing, billing, data analysis, and user management can be provided to users.

Ultrasonic parking guidance technology detects the usage and availability of parking spaces in real time through ultrasonic sensors installed above the parking spaces. When the vehicle approaches, the sensor will emit a signal to guide the driver to find an available parking space. This technology not only improves parking efficiency and reduces the situation of drivers blindly searching for parking spaces in the parking lot, but also helps alleviate the traffic pressure in the city, reduce the risk of collisions between vehicles, and enhance the safety of the parking lot.

The wireless geomagnetic parking guidance technology has received widespread attention for its high efficiency, accuracy, convenience, and energy-saving and environmentally friendly characteristics. The system monitors parking space information in real time through geomagnetic sensing technology and provides real-time information to drivers through indicator devices, thereby helping drivers quickly find available parking spaces. In addition, the wireless geomagnetic parking guidance system also has the advantages of energy conservation and environmental protection, as it uses wireless networks for information transmission, avoiding the wired network wiring problems in traditional parking lot systems and reducing energy consumption.

In the smart parking revolution, the integrated application of these technologies has brought unprecedented changes to parking lots. They not only improve parking efficiency, reduce vehicle waiting time, but also avoid parking accidents caused by human operation. At the same time, these technologies also provide decision support for urban traffic managers. Through data analysis techniques, they can better grasp parking demand and traffic congestion, and plan and allocate parking resources in a targeted manner.
