What Are the Differences Between Ultrasonic Parking Space Guidance and Video Parking Space Guidance-

In large parking lots, people are used to guiding parking according to the parking space guidance screen inside the parking lot. The data of the parking space guidance screen gives feedback after being processed by the parking lot system. The specific working principle is related to the use of the system in the parking lot. As the two mainstream parking space guidance systems, apart from starting later than ultrasonic parking space guidance, what are the differences between them? How should parking lot managers choose? Different working principles: the most intuitive way to distinguish between ultrasonic parking space guidance system and video parking space guidance system is to look at the parking space detector used above the parking space. Ultrasonic parking space guidance uses ultrasonic detector to judge the use of parking space by using the time difference after ultrasonic transmission, reflection and echo reception. The video detector captures the picture information of the parking space through the camera above the parking space, and uses the image processing technology to identify whether the parking space is occupied by vehicles. The ultrasonic detector can only judge whether the parking space has a vehicle or not, and can not do more complex work. The video parking space guidance can recognize the license plate on the picture, so as to obtain the detailed information of the vehicle, such as the license plate number. Expansibility difference: because the video parking space guidance can identify the specific vehicle information of the parking space, it is often used with the reverse vehicle search system. The parking space information pictures collected by the reverse car search system through the video parking space guidance and the data after analysis and processing are stored in the server background. When the owner inputs the corresponding vehicle information through the in-field reverse query machine or app, the data is uploaded to the server and compared with the repository, and finally gives the specific vehicle parking position information or no corresponding information of the vehicle. If the ultrasonic parking space guidance system needs to realize reverse vehicle search, it may need to introduce more things to realize it. Transmission speed difference: the ultrasonic detector guided by ultrasonic parking space communicates through RS485, and the transmission speed is general. The parking space camera guided by video parking space communicates through TCP, with relatively fast transmission speed, simple wiring and convenient maintenance. Understand the working principle of ultrasonic and video parking space guidance system, which is convenient for parking lot managers to clearly understand their functional characteristics, and then select the appropriate parking space guidance system according to the needs of parking lot. However, in reality, there is a certain gap between the price of ultrasonic detector and parking camera equipment. When the number of equipment is large, the cost will increase by multiple, so the parking lot manager should make a correct choice according to the actual situation.
