Active RFID vehicle automatic identification and anti-theft system
application scheme
1. Challenges and needs
With the rapid development of my country's economy and transportation, the
total number of vehicles in my country has exceeded 60 million at this stage,
and it is growing at an annual rate of more than 10%. With the increase in
vehicles, violations such as evading annual inspections, embezzling license
plates, using fake license plates, and modifying stolen vehicles are
increasing.
In the past, the vehicle management department mainly relied on the
establishment of cards and spot checks, temporary additional police and
personnel on duty to manage violations of regulations and laws. This method of
governance is extremely inefficient, and on-site verification is very difficult.
In terms of solving vehicle theft prevention, the GPS system is complicated and
the charges are too high. In this case, RFID technology can be combined to
achieve the goal of reducing costs.
2. Application scheme
2.1 Vehicle automatic identification system based on active RFID
This system includes vehicle-mounted radio frequency tags, fixed card
readers and mobile card readers.
2.1.1 Car radio frequency tags
Vehicle-mounted radio frequency tags have unique IDs in the world, and
carry vehicle information, vehicle status, and vehicle owner information. The
identification ID and its information are stored in the information exchange
network of the public security department. Generally, they are in a static state
and only start until the car is stolen or the car owner requests traffic
information inquiries. This identification number can help the police identify
and track stolen vehicles. Vehicle-mounted radio frequency tags must be
installed firmly, reliably, and concealed, and can be treated with
tamper-evident treatment. Once they are disassembled, they will automatically
alarm.
2.1.2 Fixed card reader
The reading distance range of the fixed card reader is 2 to 80 meters, and
the fixed card reader is used to check, identify and record passing
vehicles.
When a vehicle carrying an RFID tag passes near the fixed card reader, the
card reader reads the ID in the tag, superimposes the passing time and transmits
it to the server, and the server transmits the collected vehicle data
information to the police station via the Internet. The management center of the
transportation department also issues the control instructions of the management
center to decide whether to release or intercept vehicles.
2.1.3 Mobile card reader
The mobile card reader can be equipped on a police car, which can be
started at any time and parked in a designated place to conduct surprise
inspections and identification of passing vehicles. The mobile card reader can
be installed on the police car to keep in touch with the command center through
the GPRS module.
2.1.4 Handheld card reader
Inspectors can use hand-held card readers to check passing vehicles at
specific locations. The handheld card reader has downloaded the stolen vehicle
information in advance, and once the same information is read, it will
immediately call the police.
2.2 Anti-theft network based on active RFID and GPS
This system consists of a fixed card reader, a mobile card reader, a GPS
positioning and navigation system, and a GPRS communication system. The
schematic diagram is shown in Figure 1.
