With the rapid development of large and medium-sized cities, the number of car ownership continues to increase, and the existing parking resources in the society are far from satisfying the public's demand for parking spaces. The data shows that the average parking space utilization rate in our car parks is only 30%, and the larger the parking lot utilization rate, the lower. Resolving the difficulties of parking has become a problem that has plagued all parties in society. It has also become the focus of attention from all walks of life. "Internet of Things + Parking Lot" is based on the Internet of Things and cloud computing technology, wireless communication technology, computer network technology and other advanced means, combined with cloud parking service platform, each parking lot can be staggered with each other, make full use of the city's idle resources to solve parking It is undoubtedly one. Three-tier Internet of Things technology supports efficient parking at your fingertips Internet of Things helps boost parking efficiency The so-called "Internet of Things + Parking" means smart parking. In simple terms, automation technology is applied to urban parking space collection, management, query, reservation and navigation services, so as to maximize the utilization of parking space resources and maximize the profits of parking lots. The car parking service is optimized. At the same time, smart parking has a good performance in the area of ​​parking at the wrong time. The government encourages the use of parking berths to be shared between commercial and office buildings and residential areas, and guides the opening of parking lots within enterprises, public institutions and public institutions. It also allows individual parking spaces to be rented in the wrong place. And get revenue. Smart parking can also help the city to reduce congestion and pollution. With the help of smart parking, owners no longer need to drive around to find parking space. In addition, smart parking can help owners search for their own car. Simply enter the license plate number in the parking lot through the inquiry machine or two-dimensional code scanning, and you can quickly obtain parking space information and electronic map display. Parking lot payment will also become very convenient, whether it be a pos machine, parking lot self-service payment machine or mobile phone mobile payment, QR code payment can be completed. Smart parking uses the Internet of Things technology to directly improve the quality of life of urban citizens. What are Internet of Things technologies in smart parking? We can classify smart parking as city-level, library-level, and parking-level. The next IoT technology in smart parking is discussed from these three levels. In the city level, parking facility data is uploaded to the urban platform through the Internet of Things, and the government-level cloud platform and the parking company cloud platform are connected online to obtain parking lot data to form a “one net†pattern for the citywide parking lot. On the public service, it is convenient for the public to find the parking space, and it can also solve the problem of “escape single†for some parking users. Its main application is NB-IoT technology and LoRa technology. NB-IoT technology and LoRa technology: The NB-IoT technology and LoRa technology that emerged this year are technologies applied in city-level smart parking. The NB-IoT technology utilizes low-bandwidth communications, low power consumption, wide coverage, and high density to make parking facilities directly accessible. Networking, geomagnetics, ground locks, charging piles, and barrier gates can transmit information continuously to network platforms. LoRa technology has formed industry norms and a common platform in recent years, which can make the community networking form a large network. The library-level application scenarios include parking lots, parking garages, roadside parking, etc. The main use of RFID is the use of RFID, license plate recognition technology, and electronic stop-to-stop (ETC) technology. RFID: The introduction of RFID technology, using its features without the need for manual intervention to automatically identify, can realize smart parking access management, change the efficiency of the entrance and exit traffic caused by the traditional parking lot parking card, exit card payment, and improve the traffic efficiency. License plate recognition technology and ETC technology: These two Internet of Things technologies are mainly technologies used in smart parking at the library level. The license plate recognition technology uses the camera to photograph the license plate or ETC to accurately identify the vehicle's identity, record the time of entry and exit of the vehicle to accurately charge, and allow the vehicle to pass quickly without manual recording. It is worth mentioning that ETC technology is an important technology for the rapid development of smart parking barriers in recent years. However, in recent years, the Star Star "vertical circulation type" three-dimensional parking garage, the core technology is still a mechanical technology, intelligent control still uses the traditional PLC control. The parking spaces include smart car lock technology and geomagnetic technology. Smart car lock technology: Through the use of Bluetooth technology to control the lift of the car, the car lock rises, the car cannot enter the parking space, the car lock is lowered, and the corresponding vehicle enters. Geomagnetic technology: The use of wireless sensor technology to identify the earth's magnetic field, once the induction vehicle into the car, they began to charge. This requires that a set of sensors must be installed in each parking space. These sensors report data to nearby drivers in real time so that drivers can find available parking spaces in the shortest time. In this case, these battery-powered sensors are required to have long-distance communication capabilities and provide very accurate accuracy while also minimizing false alarm rates. Conclusion: Smart parking is to solve the problem of urban parking. It can be seen that smart parking is an important part of the city. It is based on the efficient management of parking lots. The driving force for development is the ecology of the automotive market, and the ultimate goal is to upgrade the economy of parking spaces. In addition, the intelligent parking system can also pool the scenic spots, municipal public parking lots, and personal idle parking spaces to form a larger industrial scale and drive positive development of the industry. According to calculations, the static parking fees market in China is about 500 billion yuan, and it is still in the initial stage of informatization. In the future, parking lots will share real-time parking information, evolve into smart parking systems, and eventually be integrated into the city’s smart transportation system. Aluminum profiles have emerged as essential building materials, revolutionizing the construction industry with their versatility, durability, and aesthetic appeal.
