With the progress and development of society, people's lifestyles have undergone profound changes. Traffic congestion in the city is one of the phenomena caused by this change. The city's traffic congestion and even chaos caused by traffic facilities have caused great inconvenience to people's lives, forcing people to seek high-tech effective means to solve this inconvenience. The intelligent parking lot is a high-tech product that meets the needs of this era.
According to the data, the first-tier cities in East China, such as Suzhou, Nanjing and Shanghai, have planned to build large-scale three-dimensional parking lots in several major transportation hubs throughout the city for many years. The construction of a large parking lot will help to improve the tightness of the parking space, but it also brings management problems for large parking lots. As for the parking lot of the Harbour Plaza, there are nearly 1,200 parking spaces. The owners who occasionally parked in the car often spend more than half an hour searching for their own vehicles because they can't figure out the original parking position. How can I effectively detect whether there is a vehicle in the parking space? How to effectively solve the parking statistics in large parking lots has become an urgent issue. RFID technology powers smart parking applications.
Parking demand analysis and RFID application background
The construction of transportation infrastructure and vehicle safety management are an important issue that every urban construction planner is facing. The intelligent parking lot is suitable for various public places (communities, enterprises, government agencies, airports, railway stations, hotels, supermarkets, etc.). In these places, there are widespread problems of difficulty in parking and difficult parking management. Especially in some high-end communities, enterprises, and government agencies, the contradiction is increasingly prominent, parking management is full of loopholes, and disputes between owners and property management parties continue. The RFID parking lot application can effectively solve these problems, enabling the owners to have a more convenient and comfortable parking environment, making the work of the parking lot management department more complete and easy. Not only can it establish a new image of property management, but it can also strictly manage the charging management process and effectively strengthen the safety management of vehicles.
The RFID intelligent parking lot is based on the mature development and successful application of RFID technology in the international industry, which is increasingly popular in China. Its non-controllability, anti-interference, anti-impact, fast identification, intelligent identification and other features, no doubt provides a new solution for all types of parking management.
RFID technology applied to intelligent parking system
With the support of advanced technologies such as advanced communication technology, sensor technology, and automatic control, people realized real-time management of â€œsmart parking lotâ€, and RFID technology perceives vehicle entry and exit applications. According to reports, RFID technology, also known as radio frequency identification technology, is a communication technology that can identify specific targets and read and write related data through radio signals without establishing mechanical or optical contact between the system and a specific target. RFID technology can read multiple vehicle information in batches by radio waves, and its practicability far exceeds bar code recognition.
RFID technology breaks through the technical bottleneck of parking lot management. Its basic working principle is that after the tag enters the magnetic field, it receives the RF signal from the reader, and sends the product information stored in the chip by the energy obtained by the induced current, or actively sends some A frequency signal; the reader reads the information and decodes it, and sends it to the central information system for data processing.
In the general parking lot, due to the continuous entry and exit of vehicles, the parking space changes are relatively large, and it is often difficult to carry out effective management. RFID technology concentrates on the application of many high-tech technologies such as radio communication, computer network, information processing and automatic control in highway automatic toll collection system. It uses the on-board electronic tag to automatically exchange information with the microwave antenna installed on the road side or the gantry. The central control computer recognizes the tag of the vehicle according to the information stored in the electronic tag, which greatly reduces the management difficulty of the parking lot.
When the vehicle enters the lane with the RFID technology and drives through the ground-sensing coil set in the lane, the ground-sensing coil generates an induction to generate a pulse signal, and the pulse signal activates the radio frequency identification system; controlled by the reader/writer The unit controls the antenna search to see if there is an effective reading and writing range of the electronic tag into the reader. Readers can be read or read-write devices depending on the structure and technology used, as the core of RFID system information control and processing.

What are the sensing functions of the RFID intelligent parking system?
As far as the functions of the RFID intelligent parking system produced by a certain enterprise are concerned, in addition to the charging standard self-loading, equipment monitoring and management, the gate function perfecting security and flood prevention, and the one-card one-car logical interlocking function, there are other Intelligent features.
1) License plate recognition system
Through the automatic license plate recognition system, the phenomenon of vehicle theft can be effectively prevented. When the vehicle reads the card or takes the card into the parking lot, the system will take the license plate and save the picture as the information of the vehicle entrance inspection to the database of the owner of the computer. When the vehicle reads the card and leaves the parking lot, the system The license plate will also be photographed, and the picture will be saved as the vehicle inspection data in the database of the owner of the computer. At the same time, the license plate image comparison display will be automatically called out to confirm the correct use of the vehicle. This enhances the anti-theft function and makes the after-the-fact inspection more accurate and easy.
2) Information display
The high-brightness LED display, even in the outdoor sunlight, the displayed information is still clearly visible, the information content is concise and concise, that is, the driver can be clearly prompted without delaying the time of vehicle entry.
3) Voice prompt
The sound prompt is convenient and thoughtful. The pluggable digital voice module facilitates system integration and upgrade, and has large storage capacity to meet the output of various voice prompt information.
Full video smart parking is the future development trend
The intelligent parking lot can solve the problems of people's parking difficulties during the parking process, difficulty in finding a car, slowing the passage speed, and single payment method. It is a modern parking lot that fully meets people's actual needs. Many advanced security technologies have been introduced in the domestic smart parking lot, and the high-definition camera will play a more important role.
With the development of security technology, the development direction of domestic parking lots will tend to move in the direction of full video smart parking lot. The â€œsmart parkingâ€ model of management and service integration is gradually gaining favor from more consumers.
The future full-video smart parking lot will serve as a comprehensive solution for parking problems. It has excellent advantages in integrating parking system resources, enabling fast entry from the vehicle, fast parking, and quick return to the vehicle when the owner returns to the yard. A full range of fully automated features such as payment. Therefore, the parking lot including public places such as shopping malls and airports can be effectively optimized due to the large traffic volume, slow parking, slow payment, difficult parking, and difficulty in finding a car.
