In addition to the globally unique ID code, the identification information can also be the vehicle's chassis number, vehicle appearance information, etc. It should be noted that the specific content of the identification information is not limited here, as long as it can enable vehicle identification. Here, the signal emitted by the antenna of the RFID electronic tag 1 located at the first hole position 3, after passing through the other holes besides the first hole position 3, can affect the electromagnetic transmission characteristics through coupling. That is to say, the RFID chip is a circuit, and the license plate body 2 is a circuit. These two circuits form a coupling network. When the signal in the RFID chip changes, an electromagnetic field is formed. This electromagnetic field is transmitted to the license plate body 2 through the other holes besides the first hole position 3.

Furthermore, the anti-counterfeiting watermark can quickly determine the authenticity of the electronic license plate, increasing its anti-counterfeiting capability and further improving its reliability.

[0059] In one possible embodiment of the utility model, the electronic license plate works as follows: First, the electronic license plate with an RFID tag is installed inside the vehicle's camera frame, for example, by drilling holes with ordinary screws. Then, when identification of the electronic license plate is required, the signal emitted by the RFID tag's antenna is first amplified by a second aperture. After receiving the RFID tag's RF signal, the reader antenna decodes and processes it to obtain the identification information from the RFID tag. The reader then transmits the decoded information to the host or application software system for processing. The application software system further analyzes, stores, or transmits the information according to business needs. While obtaining the vehicle license plate identification information, the reader can also obtain more information about the vehicle by reading the QR code on the electronic license plate, such as vehicle ownership information, including the vehicle identification number, owner's identity information, and vehicle registration certificate number. Furthermore, it can further verify the authenticity of the electronic license plate based on anti-counterfeiting marks and watermarks.

[0060] In one embodiment of the utility model, an identification system is also provided, comprising: an electronic license plate and a processor according to any of the above embodiments; wherein the processor is used to emit a radio frequency signal, the electronic license plate is used to send a signal carrying the identification information of the vehicle to the processor after detecting the radio frequency signal emitted by the processor, and the processor is used to identify the vehicle based on the identification information carried in the signal after receiving the signal.

[0061] In this embodiment of the invention, the processor can be an RFID electronic tag reader / writer. The RFID electronic tag consists of an RFID chip and an antenna. The chip stores the identification information of the vehicle license plate number. When the RFID electronic tag enters the working range of the reader / writer's antenna, the antenna of the RFID electronic tag receives the radio frequency signal emitted by the reader / writer and generates an induced current through electromagnetic induction. The induced current drives the RFID chip circuit, activating the tag chip. After the chip circuit is activated, the identification information stored in the tag is sent to the reader / writer through the antenna. The signal emitted by the antenna of the RFID electronic tag located at the first aperture can be coupled to the license plate body through electrical coupling when it passes through the second aperture, thereby increasing the gain of the emitted signal. After receiving the radio frequency signal sent by the RFID electronic tag, the reader / writer's antenna decodes and processes it to obtain the identification information in the RFID electronic tag. The reader / writer transmits the decoded information to the host or application software system for processing. The application software system performs further analysis, storage, or transmission of the information according to business needs. It should be noted that the recognition system can be applied to different scenarios according to actual needs. For example, parking lots can use the recognition system to manage parking fees for vehicles, and traffic cameras can use the recognition system to manage traffic penalties for vehicles. It should be noted that the specific application scenarios of the recognition system are not limited here.

[0062] According to the identification system provided in this embodiment, the processor and the RFID electronic tag do not need to be in direct contact to achieve information identification and transmission. Furthermore, based on the processor's transmission power and the RFID electronic tag's antenna design, the identification system can achieve identification over long distances. Since the identification system in this embodiment uses radio frequency technology, it has high anti-interference capability and stability, and the RFID chip can store a large amount of identification information, meeting the needs of various application scenarios. The reading and writing operations of the identification system in this embodiment are simple and quick; simply bringing the RFID electronic tag close to the reader is sufficient to complete information reading and writing, improving the convenience of identification.
