What is an ultrasonic parking guidance system
The parking guidance system is mainly used in intelligent parking lots to effectively guide and manage parked vehicles, thereby achieving quick parking for car owners and improving the efficiency of parking lot management. In addition, the parking guidance system can also monitor parking spaces in real time, making parking lot management more standardized and orderly, and improving parking space utilization. Ultrasonic parking guidance system is a common type of parking guidance system, which uses ultrasonic detection technology in the parking lot to reliably detect the occupancy or vacancy status of each parking space. Installing ultrasonic detectors above each parking space can detect whether a vehicle is parked in the parking space. The management system collects all detection information in real time and feeds back the guidance information to each guidance indicator signal through the computer in real time. The intelligent ultrasonic parking guidance system is a system that installs ultrasonic parking detectors on parking spaces in the parking lot to detect the status of parking spaces in real time. On the one hand, the detected parking space status is visually displayed through parking indicator lights. On the other hand, the parking space occupancy status information is directly transmitted to the parking space guidance screen to release vacancy guidance information to car owners, helping users arrive at the vacant space as soon as possible. This effectively improves the throughput and utilization of parking spaces in the parking lot, provides comfortable parking experience for car owners, attracts people and gathers popularity, and brings business opportunities to your business operation. The intelligent ultrasonic parking guidance system consists of three parts. The first part is the data acquisition system, which consists of vehicle detectors and controllers. The second part is the central processing system, which analyzes the collected data and displays it on the corresponding output devices. The third part is the output display system, which consists of a display screen and guide signs.
1. The principle of use is different: the ultrasonic detector adopts the principle of ultrasonic distance measurement, using the time difference between ultrasonic emission, reflection, and echo reception to determine the usage status of the parking space.
The video detector captures real-time images of parking spaces, using image processing technology to monitor the usage status of parking spaces through image comparison, and using front-end recognition methods to identify license plates.
2.Different transmission speeds: The ultrasonic solution uses RS485 communication, which has a moderate transmission speed, while the parking guidance and reverse car search systems are two relatively independent systems that use RS485 communication. They are difficult to manage, have a large number of devices, and require complex construction wiring, which affects the aesthetics of the parking lot. On the other hand, the video parking guidance system and reverse car search system can achieve data synchronization, pure TCP communication, and easy wiring and maintenance.
3. The car search methods are different: the former uses IC card positioning to search for cars, while the latter uses full video car search.

Ultrasonic parking guidance system: Its main working principle is to detect the usage status of parking spaces based on ultrasonic detectors. The system will statistically process the real-time empty parking space status and publish it on the indoor information screen and entrance/exit information screen. At the same time, the parking space status indicator lights above each parking space will switch the indicator status based on the detection results of the ultrasonic detector, guiding the driver to park conveniently and achieving humanized service.
