Central Technology and Main Application Analysis of Intelligent Parking System Construction

Smart parking refers to the comprehensive application of wireless communication technology, mobile terminal technology, GPS positioning technology and GIS technology to the collection, management, query, reservation and navigation services of urban parking spaces, so as to realize the integration of real-time update, query, reservation and navigation services of parking space resources, and maximize the utilization rate of parking space resources Maximize the profit of parking lot and optimize the parking service of car owners.

The "wisdom" of smart parking is reflected in: "smart parking space automatic parking fee payment". It serves the owner's daily parking, wrong time parking, parking space rental, car aftermarket service, reverse car search and parking space navigation.

Offline intelligence is reflected in making parking people better Park in parking spaces. First, fast traffic to avoid the problems of relying on people to manage the parking lot in the past, opaque charges and large time-consuming in and out of the parking lot. Second, provide special parking spaces, such as wide model parking spaces, novice driver parking spaces, charging pile parking spaces and other diversified and personalized consumption upgrading services. Third, park more cars in the same space.

The purpose of smart parking is to make it easier for car owners to find parking spaces, including offline and online wisdom. Online intelligence is embodied in the use of mobile phone APP, WeChat and Alipay to obtain the car park, parking space information, charging standard, whether booking, charging and sharing services, and realize the functions of pre payment and online checkout. Offline intelligence is reflected in making parking people better Park in parking spaces.

First, fast traffic to avoid the problems of relying on people to manage the parking lot in the past, opaque charges and large time-consuming in and out of the parking lot.

Second, provide special parking spaces, such as wide model parking spaces, novice driver parking spaces, charging pile parking spaces and other diversified and personalized consumption upgrading services.

Third, park more cars in the same space. For example, a three-dimensional parking garage can expand the number of parking per unit space; Shared parking can solve the problem of vehicle parking in different periods.

During the construction of intelligent parking system, the following technologies are mainly applied and involved:

License plate recognition is an automatic pattern recognition technology for license plate number and license plate color by collecting dynamic video or static images of vehicles. The core of the technology includes license plate location algorithm, license plate character segmentation algorithm and optical character recognition algorithm. A complete license plate recognition system should include vehicle detection, image acquisition, license plate recognition and so on.

The parking lot can realize the automatic timing and charging of vehicles by installing the license plate recognition equipment at the exit, recording the license plate number and access time of vehicles, and combining with the control of automatic door and railing machine. When the vehicle detection section detects the arrival of the vehicle, it triggers the image acquisition unit to acquire the current video image. The license plate recognition unit processes the image, locates the license plate position, segments the characters in the license plate for recognition, and finally forms the license plate number output.

Parking space guidance technology is a very important part of the development of intelligent parking. It can help car owners quickly find parking spaces, avoid driving blindly, eliminate car owners' worries about finding cars, effectively improve traffic road utilization and alleviate vehicle congestion. At present, there are two mainstream smart parking spaces in the market: ultrasonic and video.

1. Ultrasonic parking space guidance system

The ultrasonic detector is installed above the parking space, and the characteristics of ultrasonic reflection are used to detect whether there is a parking space below the parking space, so as to guide the vehicle through the system. The ultrasonic guidance system is suitable for parking lots with large traffic flow and tight parking spaces. It can help car owners understand the free parking space information in real time and quickly, so as to park quickly and efficiently.

2. Video parking space guidance system

The camera is installed above the parking space, and the video is used to analyze whether there is a parking space below the parking space, so as to guide the vehicle through the system. The video guidance and vehicle finding system is suitable for large commercial squares and airports with large traffic flow and relatively chaotic management.

In shopping malls, shopping centers and other large parking lots, when returning to the parking lot, car owners are often easy to lose their way in the parking lot and can't find their own vehicles due to the large parking space, similar environment and signs, difficult direction identification and other reasons. The reverse vehicle retrieval system detects the vehicle through the video parking space detector, and the video is transmitted to the identification terminal through the switch. After identifying the license plate, parking space and other information, it is transmitted to the data server through Ethernet, and finally shared with each query terminal, Just input the license plate number or other relevant information on the query terminal to help users find the parking area as soon as possible.

4 Mobile payment of parking fee

Traditional parking lot payment generally takes cash payment as the main means, and it is manual charging. However, the loophole of manual charging is too large. Property managers can't know the charging situation from time to time. The statistical statements are not timely, which wastes human and material resources and costs high. In Internet plus car park, many parking lots are upgraded by parking smart car park facilities to guide users to pay online. This saves parking time to a certain extent and brings convenience to parking lot management.

To solve the problem of "difficult parking", intelligent parking mode has the highest recognition and support rate in the eyes of the public, and is regarded as the most effective means to solve urban static traffic problems. Of course, to be universal, we need to make more use of high and new technology.

Emergency events such as vehicle scratch and collision, occupied parking space and failure to open and close the gate caused by various problems occur from time to time in the parking lot. Therefore, the one button call intercom system is still a necessary system in the parking lot, and its role in the unattended parking lot will become more important.

With few points and long distance, it is difficult for the service end to have fixed personnel to stick to it for 24 hours. These common problems of one button call intercom system applied in traditional parking lots will become particularly prominent in unattended parking lots. The new generation of one key call intercom system should not only solve these problems and make the one key call intercom system play its original role, which can greatly improve the user experience of unattended parking lot, realize fast (convenient service), accurate (accurate problem), clear (clear communication) and zero (zero communication distance), but also reduce the comprehensive operation cost of parking lot. To achieve the above requirements, we must pass

1) Audio and video processing (including hardware terminal and cloud), audio and video internet communication, mobile Internet and other technologies improve the user experience of products and better serve customers.

2) Cloud Architecture to achieve centralized operation and maintenance and scheduling and reduce comprehensive costs.

The one button call visual intercom system ensures the closed loop of the unattended overall scheme and provides a perfect customer service experience.

To realize the problem of "unattended parking deployment", intelligent parking mode has the highest recognition and support rate in the eyes of the public, and is regarded as the most effective means to solve urban static traffic problems. Of course, to be universal, we need to make more use of high and new technology.

6 Big data management combined with remote operation and maintenance

Based on the continuous accumulation of daily operation data between the management and vehicle owners, the customer's hardware system is networked through the intelligent management platform to generate a big data platform. Customers can remotely maintain the system hardware and greatly improve their management efficiency. At the same time, the big data platform analyzes the traffic flow, passenger flow and information flow, provides data support for customers' business decisions and promotes customers' business transformation, The big data platform business is especially suitable for large-scale networked group property management.
