1. Introduction to the system
The system usedRFIDThe technology is combined with the vehicle barrier management system to provide an independent and uninterrupted data collection system to achieve the requirements for automatic inspection and release management of vehicle traffic. The RFID gate vehicle management system is an electronic tag that writes vehicle information into the vehicle or on the windshield.When attachedelectronic labelWhen the vehicle passes through the lane controlled by the reader, the reader automatically obtains the information of the passing vehicle in a non-contact, long-distance reading manner, and based on this, the passing vehicle is automatically registered, whether to release, and tolls.
1.1 System composition
The RFID gate vehicle management system is an intelligent management system involving card issuance, data collection, information processing, and barrier systems.
Issuing card:
The RFID gate vehicle management system writes the key data of the vehicle, including the vehicle itself and its own information, into the electronic tag card through the card issuing device. After the writing is completed, the card is fixed on the vehicle body or pasted on the window glass.
data collection:
The RFID gate vehicle management system is when the vehicle passes through, the data collection system includes the collection of data in the radio frequency card by the RFID reader and the collection of the license plate information by the license plate video recognition system.
Information processing:
The computer analyzes and processes the collected data. This includes comparing the new data with the original data in the database. Finally, the corresponding instructions are given.
Barrier gate system:
The RFID gate vehicle management system is composed of a set of hardware equipment such as metal stoppers, channel controllers, vehicle detectors, central processing units, and ground sensing coils. Finally realize the prohibition and release of vehicles.
Overall system configuration diagram
Two, program introduction
The RFID gate vehicle management system uses two systems, a radio frequency RFID identification system and a video license plate recognition system, to simultaneously detect the legal identity of the vehicle. Eventually, the purpose of legally-identified vehicles entering the unit without having to stop and getting out of the unit with the judgement of the guards is realized.
work process:
2.1 Partial process of vehicle entrance
2.2 Fixed card vehicles
The RFID gate vehicle management system is when the fixed card vehicle enters the entrance lane when the RFID reader device antenna covers the area, the RFID reader reads the relevant information of the electronic tag installed on the vehicle and uploads the data to the computer. When the data is verified to be valid and correct, the automatic barrier will raise the railing, and at the same time automatically activate the entrance camera to record an image of the vehicle, and store it in the computer hard disk of the gate management office according to the corresponding card number. The vehicle can enter without stopping; if the collected electronic tag data cannot match the original data in the database, the car blocking lever will not be lifted, and the door guard is required to check whether there is any problem with the incoming car.
Part of the process of vehicle export:
2.3 Fixed card vehicles
When the fixed-card vehicle is ready to drive out of the area covered by the RFID device exit antenna, the RFID reader reads the relevant information of the card, and the data is uploaded to the central computer for verification. Comparing the photos of the car in the database with the actual car, the system detects the vehicle without any problems. Control to raise the gear lever and the vehicle drives out; if there is RFID collected data that cannot match the original data in the database or the photos in the database do not match the actual vehicle, the door guard is required to check whether there is any problem with the vehicle.
