A 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 toll, computer management, closed-circuit television monitoring and detector verification”. , Vehicle management is moving towards digital infrastructure.
The basic block diagram is as follows:
Two practical 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). Safety management of one card and 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 the corresponding information in the computer, and the card can be reissued in time if it 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, the computer prompts and warns at any time, and you are not allowed to leave.
(4) High anti-counterfeiting Because the RFID card has extremely high confidentiality, its encryption function can’t be solved by a computer after 10 years, so it is not easy to forge.
Three system composition
Electronic license plate (store corresponding vehicle information), driver card (optional, store corresponding driver information, mainly for the purpose of strengthening supervision), access control antenna, remote reader, access controller, access control computer, software including management Software and card writing software
Four: System workflow
When the vehicle enters/exits the access control antenna communication area, the antenna uses microwave communication to exchange two-way data with the electronic identification card, read the relevant information of the vehicle from the electronic car card, and read the relevant information of the driver from the driver card , Automatically recognize the electronic vehicle card and driver card and judge whether the vehicle card is valid and the legitimacy of the driver card, the lane control computer displays the license plate number and driver information corresponding to the electronic vehicle card and driver card one-to-one; lane control computer The relevant information of passing time, vehicle and driver is automatically stored in the database, and the lane control computer judges as follows based on the data read:
◇ Normal card: When the license plate number and driver card read are legal, the movable door opens automatically (3 meters), and the movable door closes automatically after the vehicle leaves the exit coil;
◇ Unauthorized card: When the read card or driver card is unauthorized, the system will alarm and capture and save the picture, and the movable gate will not open;
◇ No truck: When the vehicle triggers the exit coil and the system does not read the vehicle card and driver card, the system determines that there is no truck, the system alarms and captures and saves the picture, and the movable door does not open;
◇ Illegal card: a card that is not from the company, although the data is read by the card reader, but not the company, the system alarms and captures and saves the picture, and the movable door does not open.
Five, system characteristics
This intelligent parking lot system is a computer network composed of a management system and a channel identification system, and the network communication protocol adopts the TCP/IP protocol. This system can effectively, accurately and intelligently identify, collect, record and park the data information of system vehicles (vehicles with electronic license plates) and non-system vehicles (vehicles without electronic license plates) entering and leaving the parking lot. , Upload, process, and when necessary, can be supplemented by corresponding manual intervention to avoid the impact of abnormal events (when non-system vehicles enter and exit), and to ensure that the access control system has efficient vehicle intelligent release capabilities.
