Project Overview
Qianmen Street is a famous commercial street in Beijing. It starts from Qianmen Moon Bay in the north and reaches Zhushikou in the south. It is a pedestrian street full of “Beijing flavor” with a total length of 840 meters. With people’s fast-paced work and life, the number of vehicles is increasing. As a centralized storage and management place for vehicles on a bustling commercial street, the underground parking lot of Qianmen Street is facing severe problems in vehicle parking management. In order to solve the parking management problem of the parking lot, Beijing Qianmen Street has tried to run the related ordinary intelligent parking lot management system. However, the ordinary intelligent parking lot management system cannot completely solve the actual problems of the parking lot in actual operation. , The parking lot cannot be officially put into use. It is understood that because the ordinary intelligent parking management system cannot correctly find their vehicle in the reverse car search, considering the long-term development of the commercial area, the Ketuo parking lot car search machine was finally introduced.
Project overall plan
The large underground parking lot on Qianmen Street is divided into two levels: Zone B1 (2nd basement) and Zone B2 (3rd basement), with a total of more than 2,000 parking spaces. At present, the 200 parking spaces of the first phase of the project have been completed at the end of September. In order to improve the level of informatization and intelligent management of the parking lot, while providing car owners with a convenient, fast and open parking environment, it can also provide convenience for car owners to find cars. The parking lot introduces Keytop parking lot to find cars machine. It is reported that the car-finder in the parking lot adopts the latest video license plate recognition technology, which not only realizes parking guidance, but also facilitates car owners to return to find a car. It is understood that the system also embeds convenient functions such as mobile phone query and mobile phone reservation to solve the user’s “difficult to find” parking environment. It is also connected with the municipal public transport card to realize automatic payment and other functions. The overall design is as follows:
1. The parking fee management system is adopted to realize the entrance and exit management and charging functions of the parking lot. Card-ticket users use license plate recognition and long-distance card inspection machines for exit parking management. Temporary users without tickets and cards use license plate recognition for on-site billing, and use the Beijing Municipal Public Transport All-in-One Card to pay for fees at the exit toll office. At the same time, intelligent management of parking space inquiries and online reservation of VIP parking spaces is realized.
2. The parking lot car search machine uses the touch screen installed at the elevator entrance of the parking lot to enter your license plate number. The touch screen displays the current location of the owner and the location where the vehicle is parked. Not only that, the system is more intimate for the owner to select a vehicle to reach the location of the vehicle. The nearest route. The thoughtful and convenient service can enhance the car owner’s impression of the parking lot, and it can also increase the circulation and utilization rate of the parking lot.
The following focuses on the practical application of the car-finding machine in the parking lot.
Parking lot car looking machine
In large parking lots such as shopping malls and shopping malls, when returning to the parking lot, car owners often get lost in the parking lot due to the large space of the parking lot, the similar environment and signs, and the direction is not easy to distinguish. . Ketuo’s car-finding system uses video image processing technology to enter the license plate number, display the location of the owner and the vehicle, and help customers find the area where the vehicle is parked as soon as possible. Improve customer satisfaction with the parking lot and even the property company to which it belongs; speed up the vehicle turnover of the parking lot, increase the utilization rate and economic efficiency of the parking lot; improve the management level of the parking lot, and improve the external image of the property company to which the parking lot belongs.
System function principle
The Ketuo parking lot car search machine installs a video parking space detection terminal in front of each parking space in the parking lot to capture the image information of the parking space in real time. The video parking space detection terminal transmits the captured parking space image information to multiple video processing The server performs processing and transfers the information to the server for unified management.
The server will send the updated data of the processed empty parking spaces to the LED parking guidance screen for display, thereby realizing the parking guidance function.
When the car owner enters the license plate of his car through the car search terminal installed at the entrance of the parking lot, the touch screen will retrieve the data from the server after receiving the instruction, and display the map of the car park where the car owner is currently located on the screen. The map will indicate the owner’s location Position the seat and the seat where the vehicle is parked, and select an optimal pick-up route according to the overall route of the parking lot and display it on the parking lot map to guide the owner to pick up the car.
