1. Background introduction:
With the continuous development of national economic construction and the continuous improvement of comprehensive strength, cars have gradually entered thousands of households. Facing the advent of the automobile age, the entire society will have higher and higher requirements for smart parking lots. The company provides the latest generation of UHF RFID radio frequency identification products. The intelligent parking lot management system composed of it will replace the traditional manual charging management method, and meet the requirements of the accelerating pace of life for today’s parking lot management. The radio frequency automatic identification non-stop toll collection system is the most novel automatic toll collection method that adopts “radio frequency automatic identification of vehicle number and vehicle type, remote electronic tag card toll, computer management, image comparison and detector verification”. Management moves towards digital and automated infrastructure.
2. Realistic significance
1. Establish a 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 fee 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 the financial loopholes are easy to cause the loss of cash. 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. Strengthened safety management
One card for one vehicle, data archiving, 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 card can also be retrieved at any time and processed in time. When equipped with image comparison equipment, all types of parking cards are archived with license plate numbers, one card is dedicated, and the license plate is not prompted to the computer at any time, and a warning is given.
4. Good anti-counterfeiting performance
Because the RFID card is extremely confidential, its encryption function can’t 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
The passive radio frequency identification card used in this system is maintenance-free, long service life, fully sealed, free of contact, dust-proof and waterproof, no need to manually open the gate, the system automatically reads, checks, and opens the gate, which saves manpower and time.
3. Technical introduction
Microwave Radio Frequency Identification (UHF RFID) technology is the most advanced fourth-generation automatic identification technology in the world. It is a new technology that has just begun to emerge in recent years and has been rapidly promoted and applied. It has the characteristics of long recognition distance, high recognition accuracy, fast recognition 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 or leaving the parking lot, the driver must also open the glass window, stretch the pass card to the card reader and shake it for a few times to raise the barrier to allow vehicles to enter and exit.
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 arrives at the gate of the parking lot, the remote card reader can judge and control the automatic lifting of the stop bar, so it is not necessary to fix the user’s vehicle parking. 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.
Four, equipment composition
The composition of long-distance card reading equipment includes:
(1) Electronic tags (also known as “cards”) The electronic tags record the legal number of the vehicle that has been affixed to the car park management office, as well as certain vehicle characteristic information deemed necessary by the system.
At present, the company’s market introduction is the UHF electronic tag imported from the United States. The tag is a passive, maintenance-free card with a reading distance of more than 7 meters. Stick it on the windshield of a car for use.
(2) Reader: used to automatically read the data on the electronic tag in the field of view of the microwave antenna, and to judge the legality of the electronic tag.
The company’s self-developed reader is a long-distance reader specifically for parking management system applications. It has Wiegand26 or RS485, RS232 and other data output interfaces, which can be used in the market in line with the above-mentioned interface standards. The controller is directly connected without changing any software and hardware of the existing parking lot management system. The reader is generally connected to the controller in the parking lot management system through the RS485 port. Each time the reader reads a card number, it automatically sends the card number to the controller. After the controller judges the card number as a valid card number, it opens the barrier and releases the car. Passable.
(3) The reader transmits signals through the microwave antenna and receives the return signals of the electronic tags.
Appendix: Electronic Label Performance Index
(1) Working frequency: 902～928MHz;
(2) The effective reading distance can be up to 10 meters (note: the distance varies due to the antenna and the transmitting power of the reader);
(3) Passive card design, no battery required;
(4) Memory capacity: 1024bits of EEPROM memory, which can be read, written, erased and then written. Store addressing and storage lock in units of words (32 bits), of which 96 Bit is used as a system parameter and is locked at the factory, and 928 Bit is a user application development area. The user can permanently write-protect the designated word area to make the application system safe and reliable;
(5) The memory can be repeatedly erased and written for more than 100,000 times, and the effective service life can reach more than ten years;
(6) Read and write rate: In theory, it takes less than 1.5ms to read 32bits from a single tag, and less than 30ms to write 32bits from a single tag;
(7) Anti-collision: The binary tree anti-collision protocol is adopted to allow reliable reading and writing when there are multiple tags in the work area;
(8) The label is encapsulated by film plastic, which has a certain anti-dismantle function;
