1. System introduction
1.1. System principle
RFID technology consists of three parts: reader, electronic tag and antenna. The tag is used as the information identifier of the vehicle to record the vehicle information.Installation at the entrance and exit of the parking lotRFIDThe reader can identify the tags in the car from a long distance, and send the identification tag information to the background system. The system compares and judges the tag information, and performs the next operation according to the judgment result, such as making automatic Registration, whether to release, and fees, etc.
RFID technology can realize rapid identification and control of vehicles at a long distance, and can judge the status of parking spaces in the field according to the entry and exit conditions of the system.
1.2. System composition
Figure 1: System composition structure diagram
The system consists of a temporary card issuing machine, a long-distance card reader, a ballot box, an electronic display card, a voice system, an intercom system and a gate. If the vehicle entry and exit photo capture function is required, a capture module, a video capture card and a camera need to be added.
2. System Features
Compared with the traditional vehicle management system, the electronic tag pass and computer authorization management system mainly have the following advantages:
Information collection automation
Vehicle information is automatically collected from a long distance to avoid manual operation and fraud. At the same time, users can query, summarize, print and other operations according to their needs, thus realizing the automation of information collection.
No parking fee
The use of RFID can realize long-distance non-parking deduction, monthly card and stored-value card holders can freely enter the parking lot, and the parking fee is calculated and confirmed by computer, which eliminates errors and cheating caused by human operation, and protects investors’ interests. Benefit.
Security and anti-counterfeiting
Using the world’s most advanced non-contact smart card technology, the anti-counterfeiting performance is good. The parked vehicle has a smart card with a unique serial number, which cannot be changed. At the same time, it adopts a two-way verification mechanism and multiple encryption technology during operation, which is uniquely identified and cannot be forged and imitated.
Prevent smashing cars
The barrier automatically rises or falls according to the traffic situation of the vehicle, and has the dual anti-smashing function of the ground sense and the pressure wave device.
Permission settings
Real-time communication can be realized by using a computer and each charging computer, and the management computer has an external line interface.
Flexible configuration
The standard industrial control system structure is adopted, and the configuration of different systems can be organized according to the different requirements of users, which is convenient and flexible.
