Example Embodiment

[0021] Next, the technical solutions in the embodiments of the present invention will be apparent from the embodiment of the present invention, and it is clearly described, and it is understood that the described embodiments are merely embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, there are all other embodiments obtained without making creative labor without making creative labor premises.

[0022] When the existing ETC electronic tag is communicating with the RSU, since the communication signal needs to pass through the car glass, there will be a certain degree of attenuation, so in some cases, especially the type of model with strong glass, it may cause the transaction failure. . Analysis found that glass-containing metal substances, antenna distance glass is too close, metal film, etc., can cause communication signal attenuation, affecting RF wireless links on the ETC electronic label, resulting in unable to...

Abstract

The invention relates to an ETC electronic tag, the ETC electronic tag comprises a controller, a power supply, a safety module and a communication module, the controller is connected with the power supply, the safety module and the communication module, and the communication module is used for communicating with a road side unit through an antenna module at least partially embedded in vehicle window glass. According to the invention, the ETC electronic tag and the vehicle window glass are combined, so that the ETC electronic tag can be well fused with the vehicle window glass, good performance of the antenna can be realized, a good radio frequency communication link is guaranteed, and the transaction success rate of the ETC electronic tag is improved.

Description

technical field [0001] The invention relates to the field of intelligent transportation (Intelligent Transportation System, ITS), in particular to an ETC electronic tag. Background technique [0002] In the ETC system, the ETC electronic tag installed on the motor vehicle adopts DSRC (Dedicated Short Range Communications, dedicated short-range communication) technology to establish a microwave communication link with RSU (Road Side Unit, road side unit), so as to realize Vehicle identification, electronic deduction, etc. [0003] The existing ETC electronic tags are generally required to be pasted on the inner side of the window glass. On the one hand, the aesthetics are poor; Certain signal attenuation, in some cases, especially for models with strong glass attenuation, may result in the inability to trade. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an ETC electronic tag for the defect of low transaction ...
