Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.

Most of the existing vehicle-mounted electronic tags OBUs are adhered to the inner side of a front windshield of an automobile by using 3M glue, and the visual field of a driver or members in the automobile can be influenced to a certain extent. Aiming at the technical problem, the vehicle-mounted electronic tag and the automobile glass are combined, and the antenna of the vehicle-mounted electronic tag is integrated into the automobile glass, so that the influence on the visual field of a user can be reduced, and the performance of the antenna can be ensured.

Fig. 1 is a logical structure diagram of a vehicle-mounted electronic tag provided by the present invention, as shown in fig. 1, including: a control module 101, a power supply module 102, a security module 103, a communication module 104, and a glass antenna 105. The control module 101 is respectively connected with the power supply module 102, the safety module 103 and the communication module 104, wherein the communication module 104 is connected with the glass antenna 105 to receive and transmit communication signals.

Further, the power module 102 may be powered by an independent battery or a vehicle-mounted power source, so as to provide stable power for each module of the vehicle-mounted electronic tag system.

Further, the security module 103 has a data storage function and a data security processing function, the data storage function stores system information, entrance and exit information and the like, and the data security processing function has data security authentication, encryption and decryption, plaintext transmission, ciphertext transmission and the like;

further, the control module 101, the power module 102, the security module 103, and the communication module 104 may be integrated on a PCB and mounted or housed in a housing, and the housing may be assembled with the PCB or may be an independent housing structure that can be fixedly connected to the window glass.

Fig. 2 is a schematic view of an installation of a vehicle-mounted electronic tag according to the present invention, as shown in fig. 2, a glass antenna 105 is composed of a glass medium and a metal covering layer printed on a surface of the glass medium, the metal covering layer on the surface of the glass medium has a feeding point, the glass antenna 105 may be integrally integrated in a vehicle glass 108, and the feeding point on the surface of the metal covering layer is electrically connected to a communication module 104 through a radio frequency cable 107, and the electrical connection may be a pluggable electrical connection. The glass medium of the glass antenna 105 may also be the automotive glass 108 itself, and a metal coating may be printed on an optional area of the automotive glass 108, and a feed point may be provided on the metal coating, electrically connected to the communication module 104 via the rf cable 107.

Further, the in-vehicle electronic tag body 106 (excluding the glass antenna 105) may be hidden inside the roof or the door window trim of the vehicle.

In the prior art, the radio frequency communication between the RSU and the OBU is attenuated or shielded due to the fact that automobile windshield glass is coated or metal substances are doped, the transaction success rate is reduced, and therefore use is affected. According to the scheme, the vehicle-mounted electronic tag and the automobile glass are combined, the antenna of the vehicle-mounted electronic tag is integrated into the automobile glass, the influence on the visual field of a user can be reduced, and the performance of the antenna can be guaranteed.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model.
