Smart parking can improve people's travel efficiency and realize the rational allocation of parking space resources. It is an important link in the development of smart city. This paper aims to analyze the development status, trend and market potential of China's intelligent parking industry, and put forward practical industry development suggestions and solutions on this basis.

Current situation and trend of parking lot with the rapid development of China's social economy and urbanization, the number of motor vehicles has increased rapidly. After nearly 20 years of blowout development, by 2019, the number of motor vehicles in China is nearly 250 million. However, due to the slow construction of parking equipment, which is far less than the growth rate of motor vehicle maintenance, the parking problem is becoming more and more serious. At present, traditional parking still occupies a large market, which requires the owner to park in the designated area under manual management. It requires manual search for parking space, reversing to find vehicles, looking for exits, parking fees and other cumbersome links, resulting in inconvenient parking. The owner often encounters the following difficulties:

There are not enough parking spaces in densely populated areas.Low utilization of parking space.Time and gasoline used to find parking spaces.

It is difficult to find vehicles in large parking lots.Traffic congestion is mainly concentrated around parking facilities.Business parking spaces are occupied by commuter parking lots.

The parking space is inconvenient.Bad parking charge mode.Unused private parking spaces.

The environmental impact of excessive fuel use when looking for parking lots.Intelligent parking system came into being

"Parking difficulty" has become a big problem facing Chinese society. But there are not many ways to solve this problem. Adding new parking spaces and reducing car ownership... It is not only difficult, but also a temporary solution. Vigorously promoting "intelligent parking system" is the most effective way to solve the problem of parking difficulty in China in the future and in line with China's national conditions and policies. When the national development and Reform Commission jointly promoted the development and application of intelligent and information-based parking, it clearly pointed out in the notice on strengthening the management of urban parking facilities that it is necessary to accelerate the promotion of intelligent parking, steadily put it into the market and alleviate the parking pressure. According to Miao Wei, Minister of the Ministry of industry and information technology, the Chinese government is promoting the digital transformation of national road infrastructure, so as to solve the problem of lack of coordination between traffic infrastructure construction and intelligent parking! This signal has further enhanced market confidence, especially for the intelligent parking ecosystem, and pushed the intelligent upgrading of parking management system to a climax. With the development of technology, with the help of the advantages of new intelligence and new interconnection, the intelligent parking system has also been continuously optimized and developed. Specifically, it 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 real-time update, query and Reservation and navigation services are integrated to maximize the utilization of parking space resources, maximize the profits of parking lot and optimize the parking service of car owners.

The development potential of intelligent parking industry is huge. The "wisdom" of intelligent parking is reflected in: "intelligent parking space search + automatic parking fee payment". It serves the owner's daily parking, wrong time parking, parking space leasing, market service, reverse car search and parking space navigation. So as to realize the integration of real-time update, query, reservation and navigation services of parking space resources, maximize the utilization of parking space resources, maximize the profit of parking lot and optimize the parking service of car owners. It is expected that in the next few years, the scale of smart parking market will continue to increase at a rate of about 20%, and is expected to exceed 15.4 billion yuan in 2020. With the advent of 5g era and the continuous maturity of Internet of things and artificial intelligence technology, the market space of intelligent parking in the future is huge.

Data source: Sinochem Research InstituteBased on the parking cost of 4000 yuan a year, the current car ownership in China is 200 million, and the static market space of parking charges exceeds trillion yuan. Whether from the perspective of the government or people's livelihood, the smart parking market has broad prospects.

Smart parking lot structure smart parking lot equipment can be divided into entrance and exit equipment, parking space detection equipment, payment or car search equipment. Among them, the all-in-one machine is gradually adopted for the entrance and exit equipment, which integrates the control machine, road gate, license plate recognition camera, fill light, information screen, switch, vehicle detector and parking lot charging software. Only one integrated control machine needs to be deployed in a single lane to realize the function of license plate recognition input port. It supports cash, QR code active scanning or being scanned, no license plate scanning, payment, voice intercom, electronic invoice and other functions, which can achieve the function of unattended sentry box. The architecture of entrance and exit parking system is as follows:

When the vehicle arrives at the entrance, enters the video recognition range or the ground induction coil detects the signal, trigger the main and auxiliary cameras at the bayonet to take pictures. The video license plate recognition software automatically recognizes the license plate number through the video stream. Video stream recognition is to quickly analyze all pictures in the video stream and intelligently select the best picture for recognition, The best results are selected as the recognition results. At the same time, the data will be uploaded to the control center in wired or wireless forms. The gate will rise automatically, the driver will drive into the site, the gate will close automatically after entering the site, and the parking time of the vehicle in the toll management system will start. The overall architecture of intelligent parking system can be divided into four layers: data acquisition layer, data exchange layer, cloud platform / server and app application, as shown in the following figure:

ZLG smart parking solution because the local smart parking system needs to support database, QT browser and large screen video playback, m6y2c core board + license plate recognition gun has become a very suitable solution. The scheme has high cost performance and integration. The block diagram is as follows:

Among them are the camera, display screen, voice playback, gate control, human-computer interaction, etc. the actual application interface can be designed with reference to the above figure. The master control platform of the scheme adopts the m6y2c core board launched by ZLG. The core board is an industrial control core board. It adopts NXP cortex-a7 800MHz main frequency processor to bring lower power consumption with advanced power management architecture. The core board is equipped with 8-way UART, 2-way USB OTG, 2-way can bus, 2-way Ethernet and other interfaces as standard; 128 / 256 / 512MB DDR3, 128M / 256M / 512M / 4G electronic hard disk and hardware watchdog are standard; Through strict EMC and high and low temperature test, ensure stable operation in harsh environments such as parking lot.

The intelligent parking management system applies parking space identification, mobile Internet and other technologies to the parking lot, which can not only quickly guide the driver to park, but also solve the problem of finding a car for the driver, and improve the utilization rate and turnover rate of parking space. At the same time, it supports car search without card, which can easily carry out reverse car search and improve the owner's user experience. It can be widely used in business districts, commercial complexes, parks / office buildings, etc.Original title: [industry sharing] intelligent parking management system to help reduce staff and increase efficiency in parking lotsThe source of the article: WeChat official account: ZLG Zhiyuan electronics] welcome to add attention!
