At present, there are two main parking space guidance systems in the market: ultrasonic technology parking space guidance and video recognition parking space guidance system. The ultrasonic parking space guidance system uses the ultrasonic principle to install an ultrasonic detector above each parking space to detect whether there are vehicles parked on the parking space. The management system will collect and transmit the parking space status to the server, the server will process the data, and then feed back the parking space guidance information to the parking space guidance display screen at each entrance. The video parking space guidance system is equipped with a video detector above the parking space. Through this video detector, you can detect whether there are vehicles in the parking space, capture the vehicle photos and license plate numbers, and transmit these information to the server. After being processed by the server, the parking space guidance information is fed back to the parking space guidance display screen at each entrance. Generally speaking, the video parking space guidance system is much more advanced than the ultrasonic parking space guidance system. The video parking space guidance system can combine the parking space guidance function and reverse vehicle search function of the parking lot to realize equipment sharing. It does not need to be like the ultrasonic parking space guidance system. If you want to realize the reverse vehicle search function, you need to install a card swiping positioning machine, This will inevitably increase a lot of quantities.
