The video parking guidance system is a parking guidance system based on video recognition technology. The system judges the current parking space status by installing a video parking space detection terminal on each parking space, thereby counting the number of empty parking spaces of the current parking lot, and then guiding the vehicle owner to quickly stop through the display of the guiding screen. The unique advantage of the system is that the function upgrade can be realized through the addition of equipment in the later stage and it is upgraded to a smart parking space guiding and video car-integrating system with the function of finding a car.
System Principe
The video parking space guiding system installs the video parking space detection terminal in front of each parking space of the parking lot, captures the image information of the parking space in real time, and transmits the captured parking space image information to the video node controller through the network cable for parking position status. Identification, and then send the identified parking status to the integrated indicator of the video parking detection terminal for red/green conversion display and communication with the central controller.
After receiving the parking space status sent by the video node controller, the central controller performs data processing, and sends a data update instruction of the parking space guiding screen to the video node controller, and the controller controls the parking space guiding screen to display, thereby realizing the parking space and Boot function.
System composition
The video parking guidance system installs an ultrasonic detector through each parking space and uses ultrasonic detection technology to detect the parking space. It can detect whether the parking space is free and send the data to the processing center, and output the information to the various indicator displays through the processing center output. . It can be seen that the parking space guiding system can be composed of three parts: an ultrasonic detector, a data processing center, and a guiding display unit.
Ultrasonic detector: Based on the principle of ultrasonic ranging, the ultrasonic wave travels in the air and immediately returns to the obstacle. By measuring the time when the sound wave is reflected back after the launch, the emission point can be calculated. The actual distance between the objects, real-time, accurate judgment of whether the current parking space is parked.
Data Processing Center: The collected data is analyzed and transmitted to the corresponding display device. Use the management computer to release relevant data to the local area network; transmit data to the system control center through GSM and wireless MODEM; and release the parking space data in the parking lot.
Guide unit: directly connected with the ultrasonic detector, used to indicate the number of spare parking spaces in the relevant direction area in the underground parking lot, usually placed in the dead end, corner, branching, etc., so that the owner can understand the vacancy of the relevant direction area at the first time. The parking space situation allows you to freely choose the most suitable area for parking, avoiding wasting time in the no-car parking area.
