1. Background introduction:
With the continuous development of national economic construction and the continuous improvement of state-owned comprehensive strength, cars have gradually entered thousands of households. Faced with the advent of the automobile age, the entire society will also enter a new property management model for smart parking lots. . Shenzhen Guoyu Information Technology Co., Ltd. provides the latest generation of self-developed UHF RFID radio frequency identification products. The intelligent access control management system composed of it will replace the old manual control management method and meet the accelerating pace of life. Today’s vehicle access control management The requirements for you to create a new image of property management and considerable economic benefits. The radio frequency automatic identification intelligent access control system is the most novel automatic toll collection method for vehicle access control that adopts “radio frequency automatic identification of vehicle number and vehicle type, remote electronic tag card charging, computer management, closed-circuit television monitoring and detector verification”. , Vehicle management is moving towards digital infrastructure. The basic block diagram is shown in Figure 1:

2. Realistic significance
(1) Establish a brand-new image of property management. The use of modern high-tech products will surely greatly improve the image and popularity of the company’s property management. Adopting the intelligent parking lot management system, both in terms of product styling and the advanced and scientific nature brought by automatic management, will establish a good image for property management and make the enterprise a model of scientific management.
(2) Strict charging management. For the current manual cash charging method, on the one hand, the labor intensity is high and the efficiency is low, and the other main drawback is that it causes great financial loopholes and cash losses. After using the radio frequency intelligent parking lot management system, all vehicle charges are confirmed and calculated by the computer, which eliminates errors and cheating and protects the rights and interests of parking lot investors.
(3) One card and one vehicle are managed in safety, and data is archived to ensure the safety of vehicles parked in the parking lot. When card issuance and card collection are performed manually, it is inevitable that there are omissions because there is no record to check at any time. Lost cars or false reports of lost cars happen from time to time, causing many troubles and economic losses to the parking lot. After adopting the intelligent parking lot management system, consumers of monthly rental cards and stored-value cards have recorded corresponding information in the computer, and the card can be reissued in time if the card is lost. Lost hourly cards can also be retrieved at any time and processed in time. At the same time, with image comparison equipment, all types of parking cards are archived with license plate numbers, one card is dedicated, the license plate is incorrect, and the computer prompts and warns at any time, and do not leave.
(4) High anti-counterfeiting Because of the high confidentiality of the radio frequency identification card, its encryption function can not be solved by a computer after 10 years, so it is not easy to forge.
(5) Durable and reliable, the operation process is fully automated, which saves both manpower and time. The passive radio frequency identification card used in this system is maintenance-free, long service life, fully sealed, free of contact, so it is dust-proof and waterproof, and does not need to be opened manually. The system automatically reads and verifies the card and opens the gate.
3. Technical introduction
Microwave radio frequency identification (UHF RFID) technology is the most advanced fourth-generation automatic identification technology in the world. It has the characteristics of fast speed, strong anti-interference ability, long service life, penetrating non-metallic materials, etc., and has a wide range of applications. The intelligent parking lot management system effectively prevents the damage and interference caused by human factors to the parking lot management through the long-distance passive radio frequency identification technology, and realizes the intelligent and scientific management of the parking lot of the building and the property community, which can control the loss of expenses and improve the operation efficiency. , To ensure vehicle safety.
The vehicle users of parking lot management are divided into two categories: (1) Fixed users: they are frequent customers of the parking lot and have to enter and exit the managed parking lot many times every day; (2) Temporary users: refer to the managed parking lot only occasionally FIT in the parking lot once. For fixed users, the existing parking lot management system uses monthly pass cards to reduce the registration and inspection procedures when they enter and exit the parking lot. However, most of the monthly pass cards currently use short-distance cards. When entering and leaving the parking lot, the driver must also open the glass window, stretch the pass card to the card reader and shake it a few times to raise the barrier to allow vehicles to enter. If you use a long-distance monthly pass card, you only need to stick the monthly pass card on the windshield of the car. Every time the vehicle reaches the gate of the parking lot, the remote card reader can control the lever to automatically lift, so the fixed user vehicle does not need to stop. , Long drive straight into. This greatly improves the traffic efficiency of vehicles and reduces pollution; at the same time, it avoids all kinds of inconveniences caused by bad weather such as wind and rain.
4. Equipment composition
4.1. Reader
It is used to automatically read the data on the electronic tag in the field of view of the microwave antenna and judge the legality of the electronic tag. The GU990A reader/writer produced by our company has data output interfaces such as Wiegand26, RS232, and network port. It can be directly connected to the controllers that meet the above-mentioned interface standards used on the market without changing the existing parking lot management system. Any software and hardware.
4.2. Microwave antenna
A customized antenna that sends and receives microwave signals to electronic tags. For parking lot applications, we chose the GUA12D antenna. The antenna has long recognition distance, large angle, convenient installation and use, and beautiful appearance.
4.3. Electronic label
The electronic tag records the legal number of the attached vehicle registered in the parking lot management office, as well as certain vehicle characteristic information deemed necessary by the system.
At present, the passive electronic maintenance-free label that our company puts on the market is in line with the agreement of 18000-6B. The reading distance can reach more than 7 meters. It is packaged with plastic film and can be placed on the car windshield behind the card holder. Used on.
4.4. Optional integrated reader
At the same time, we also withdrew from the easy-to-install and beautiful integrated reader for users to choose from. If you choose this reader, you can replace the above reader (GU990A) and antenna GUA12D. It is easy to install, but there is only one antenna, and two units may be installed at wide intersections.
4.5. Other equipment
Controllers, PCs, barriers, cameras, management software, etc. are provided and installed by integrators.
5. Device connection
The interconnection of remote card reader devices is shown in the figure:

(1) The reader is generally connected to the controller in the parking lot management system through the Wiegand port. Whenever the reader reads a card number, it will automatically send the card number to the controller. After the controller determines that it is a valid card number, it will open the channel. The brakes are released for traffic.
(2) The reader transmits signals through the microwave antenna and receives the return signals from the electronic tags. The microwave antenna is connected to the reader through a special microwave cable. The shorter the cable length is, the better. Generally, it should not exceed 3m.
