Huangshan, one of the top ten scenic spots in my country, is the only scenic spot in the country with world cultural heritage, natural heritage and world geological park, and enjoys the title of “the world’s most wonderful mountain”. It is also a beautiful cultural heritage. Landscape. In 1985, Huangshan Mountain was selected as one of the top ten scenic spots in the country. In December 1990, it was included in the “World Cultural and Natural Heritage List” by UNESCO. In February 2004, it was selected as a World Geopark. In January 2006, it was named “National Civilized Landscape”. Tourist Area”. On May 8, 2007, Huangshan Scenic Area in Huangshan City was officially approved by the National Tourism Administration as a national 5A-level tourist attraction.
Huangshan is a world-class tourist attraction, attracting a large number of Chinese and foreign tourists. In the past ten years, the average annual reception volume of Huangshan Scenic Area has been rising rapidly. The era of mass automobile consumption has prompted more people to choose to travel by car. This requires that Huangshan, which has a high number of tourists, must undergo a major renovation and upgrade in the parking lot to meet the needs of tourists. In response to this demand, Xiamen Ketuo Communications provided the Huangshan Scenic Area Transportation Bureau with a solution for the parking guidance system of the “three-dimensional parking lot”.
At present, lifting and transversal three-dimensional garages are widely used in China. For stereo garages, because the parking environment is more complex, a group of parking spaces are generally multi-layered. It is difficult for car owners to intuitively find empty parking spaces after entering the stereo garage, and often find that there are free parking spaces in the reorganized parking space after vehicles pass by. It not only consumes parking time, but also easily causes scratches between different vehicles. Based on this phenomenon, Ketuo introduced the parking guidance system independently developed by Ketuo to the Transportation Bureau of Huangshan Scenic Area, which is not only suitable for general underground parking lots, but also for stereo garages in complex environments. Because the parking spaces of the three-dimensional garage are relatively unfixed, and the steel structure pallets are often displaced, the traditional parking space detectors will inevitably be disturbed. The ultrasonic parking detector developed by Ketuo solves this problem. It can effectively resist interference and ensure the accuracy of detection data. In terms of installation, each group of parking spaces in the three-dimensional garage must have a fixed surface. Therefore, wired communication is used. Wired communication can effectively ensure the stability and accuracy of parking data transmission than wireless communication. , It has good anti-noise interference, long transmission distance and multi-station capability.
Introduction to the working principle of parking guidance system:
The parking guidance system of Huangshan Three-dimensional Garage is composed of six parts: ultrasonic parking detector, parking indicator, node controller, central controller, indoor LED parking display and outdoor LED parking display, using RS485 data communication method.
1. Detector: It is an important part of the parking guidance system. According to the fixed surface of each parking space in each group of parking spaces, ultrasonic detectors are installed respectively, and the working principle of ultrasonic distance measurement is adopted to collect real-time parking space data of the parking lot and control The display of the parking space indicator, and the parking space information is transmitted to the node controller via the 485 network in time.
2. Parking indicator: Each group of parking spaces in the garage is equipped with parking indicator on the side of the aisle to show the free status of the regrouped parking spaces. When a group of parking spaces is full, the parking indicator will show red. If there are free parking spaces in the group of parking spaces, the indicator will show green.
3. Node controller: It is the middle layer of the parking guidance system, which plays an important role in ensuring the safety, reliability and efficiency of the system. It can query the parking space information of the detector under this node in a cycle through the RS-485-B serial port. Then send the queried parking space information to the central controller through the RS-485-C serial port. And can send the control LED screen command of the central controller to the LED screen through the RS-485-B serial port.
4. Central controller: It is the core of the entire system, mainly responsible for the collection and control of the entire intelligent parking guidance system, and realizes the guidance function of the vehicle through the update of the LED real-time data screen.
5. Indoor parking space display screen: After the vehicle enters the parking lot, the owner can see the “indoor LED parking space display screen” installed above each fork in the parking space. The display screen will display the current direction of the fork road. To guide the car owner to choose the parking channel.
6. Outdoor parking space display screen: When the car owner drives to the parking lot to park, he can understand the current number of empty parking spaces on each floor of the parking lot through the display of empty parking spaces on the “outdoor LED parking space display screen” at the main entrance of the parking lot;

The renovation project of the “Three-dimensional Parking Lot” in the North Gate of Huangshan Scenic Area successfully adopted the products of Ketuo parking guidance system. The project started on March 10, 2010, and was completed in mid-October 2010 after the operation and commissioning of the peak traffic flow during the “May 1st” and “Eleventh” holidays were completed. On November 6, the completion acceptance was successfully completed. With the implementation of the “Three-dimensional Parking Lot” parking guidance system at the North Gate of Huangshan Scenic Area, Huangshan Scenic Area has become more intelligent, modern and digital. It is even more powerful to prove that Huangshan was awarded the title of “Digital Demonstration Base for Scenic Spots” in 2010, which is well deserved.
The renovation of the “three-dimensional parking lot” at the north gate of Huangshan Scenic Area was successful. Xiamen Ketuo expressed congratulations and thanks. At the same time, I would like to thank Huangshan Scenic Area Transportation Bureau for its trust and support. Ketuo will continue to work hard to walk with you.
