introduction
At present, most of the parking lot vehicle access management uses high-frequency short-distance IC cards. When vehicles enter and exit, the vehicles must be stopped, and the card is manually placed close to the card reader to read the card, and it can pass after being correctly identified.
Compared with high frequency RFID technology, UHF RFID technology has the advantages of long reading distance, fast recognition speed, identification of high-speed moving objects and multiple tags at the same time. The parking lot management system using UHF RFID technology adopts far Distance to read and write cards, no parking, no need to roll the window, can identify the RFID card on the car at a distance of 3-10 meters (adjustable), automatic control, automatic release, simplifies vehicle entry and exit procedures, and improves vehicle management efficiency. It provides great convenience to car owners and also improves the safety of vehicles entering and exiting the parking lot.

System functions
1. Vehicle access control system
1) RFID vehicle automatic identification
When vehicles pass through the entrance and exit, they can pass through the top of the gateRFIDThe read-write device automatically collects the registration information data of the vehicle card carried on the vehicle into the computer. The computer compares the automatically read data information such as the license plate number with the database information to check whether the vehicle has access rights at the entrance and exit. The system provides control commands and displays vehicle information.
2) Access control and display module
Receive the control commands issued by the computer control system, control the automatic opening and closing of the barriers, and realize automatic release operations.
2. Basic information management system
1) Vehicle information registration card issuing module
Issue an RFID vehicle card to the vehicle, record the identification code of the card, and record the relevant information of the vehicle: license plate number, vehicle type, owner’s name, unit, effective date, parking number, etc., and report to the data center for record and storage in the database .
2) Vehicle RFID card management module
Provides the maintenance and management functions of the vehicle card, including the management of the vehicle, owner, unit, card validity period and other information, the cancellation of the card, and the management of the card replacement.
3) Vehicle access authority management module
Provide authority management function for vehicles stuck at various entrances and exits.
4) Query statistics module
Query the status of vehicles, units, entrances and exits, and provide report printing in various situations.
3. Data Center
1) Data communication module
The module is divided into two parts:
The client part is installed in the access control management system, and in the computer control module, it is used to receive the access control system access data and transmit the data to the server.
The server part receives the client data and stores the data in the database.
2) Report/query module
Provide online real-time query function, can query various information of each subsystem, and provide daily report, monthly report printing, and provide report printing in various situations.
3) System maintenance management module
For system account and authority management, the system administrator assigns different functional modules and data access authority to enable ordinary users to perform their duties. At the same time ensure the safety of the system.
4) Interface module
The interface module provides various data acquisition interfaces of the vehicle access management system to facilitate the transfer of data from management software such as OA.
System Features
1. Realize the automatic management of vehicle entry and exit, avoid vehicle congestion;
2. The whole system has the characteristics of long-distance rapid identification, intelligent control, high reliability, high confidentiality, easy operation, easy expansion, etc.;
3. Strengthen the function of vehicle supervision through anti-dismantling vehicle tags and other high-tech technologies, and establish safe and reliable registered vehicle files;
4. Provide an advanced, reliable and applicable digital platform for automatic identification and intelligent management of incoming and outgoing vehicles, so that the real-time dynamic management of vehicles in and out of the logistics park can be qualitatively improved;
5. It can effectively, accurately and intelligently identify, collect, record and track the data and information of incoming and outgoing vehicles (vehicles equipped with vehicle electronic tags) to ensure the safe management of vehicles entering and exiting.
