1. System significance
1) Establishing a brand-new property image and the use of modern high-tech products will surely greatly improve the company’s property management image and popularity. Adopting intelligent parking lot management system, no matter from the aspect of product styling, or the advancement and science brought by automatic management, it will establish a good image for property management and make the enterprise a model of scientific management.
2) Strict and prudential fee management process; the original manual methods have large loopholes that can easily cause cash loss. 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) Effectively strengthen the safety management of vehicles; 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 done manually, it is inevitable that there are omissions. After adopting the intelligent parking 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 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 displayed to the computer at any time, and a warning is given.
2. System architecture and program description
The parking lot hands-free system willRFIDThe organic combination of semi-active technology (2.45G+125K), computer control technology and billing software system realizes automatic identification of inbound and outbound vehicles, automatic barrier control, automatic billing and deduction, and then fully realizes intelligent Vehicle access control. Semi-active RFID technology will completely solve the problem of vehicle adjacent lane interference, avoid the problems of mis-lifting and misjudgment in the one-in-one-out vehicle hand-free system, follow-up problems in the distance vehicle management system, and avoid the vehicle in front without a card The problem of the card being released when the vehicle is released and the vehicle anti-theft film interferes with the vehicle’s anti-theft film, which makes the long-distance entry and exit of the vehicle more smooth and convenient, and the label power consumption problem. And other issues.

2.2 Program description
The tag is placed in the car. When the car is near the barrier, the tag will be activated by the 125K signal from the ground line of the low-frequency activator. After activation, the 2.4G signal of the tag is in working state at this time, and 2.4G signal (ID number) is sent out.Long-distance omnidirectionalReaderAfter receiving the 2.4G signal (ID number) of the label, it will give a switch signal to the door opening control board. After the control board receives the switch signal, it will actively send out voltage to the door opening motor. At this time, the door opening motor works to enter and exit the door. The gate opens. After the vehicle leaves the 125K low-frequency activation area from the barrier gate, the 2.4G signal of the 2.4G electronic tag stops working, and the relay in the remote reader will stop sending a digital signal to the control board. At this time, the door opening control board will stop giving The gate motor sends in the opening voltage, the gate opening control panel will automatically give a closing voltage, and the gate will automatically close.
