Description

Technical Field

[0001] The utility model relates to the field of smart parking lots, and in particular to a parking space vacancy detection device. Background Art

[0002] The garage parking guidance and reverse vehicle search system equipped in the smart parking lot can help drivers find parking spaces in the garage and query the location of the vehicle.

[0003] The common parking guidance system is based on the camera taking photos of parking spaces, and the background recognizes vehicles and license plates through image analysis. The advantage of this technology is that it is relatively mature and can realize parking guidance and reverse car search functions at the same time. The disadvantage is that the deployment cost is relatively high, and it is easy to fail to identify in places with poor lighting. In order to reduce the cost of the system, 2 or 3 parking spaces often share one indicator light, which is not intuitive enough and is easy for car owners to ignore when driving, and it does not achieve the effect of parking guidance. In addition, the installation position is in the middle of the lane, which interferes with the traffic signs in the parking lot.

[0004] The ultrasonic parking guidance system is also a parking guidance solution. The ultrasonic parking detector is installed directly above each parking space to monitor whether each parking space in the parking lot is occupied in real time, and transmit the detection information to the system center in real time. The system center determines and outputs the idle status information of the parking space based on the real-time detected parking space status information to achieve parking guidance. Although this type of ultrasonic parking detector is cheaper than a camera, it needs to be placed above each parking space, and a central server is required to manage and configure the hardware facilities, so the cost is still relatively high.
