Embodiment Construction

[0049] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0050] see figure 1 , the automobile-specific passive UHF RFID electronic tag chip 101 provided by the present invention is composed of three core modules: a front end 102 , a baseband 103 and a storage unit 104 .

[0051] The front end 102 includes a radio frequency front end 105 and an analog front end 106 .

[0052] The RF front-end 105 is directly connected to the tag antenna, through the rectification circuit, the RF signal received in the tag antenna is converted into DC energy for use by other modules of the chip; at the same time, useful information is extracted from the RF input signal through the envelope detection circuit, and enveloped Wave detection, recovering the data information sent by the reader / writer for processing by the ba...

Abstract

The invention discloses a passive ultra-high frequency radio frequency identification (RFID) electronic tag chip special for a vehicle and a control method. The tag chip mainly comprises a radio frequency front end, an analogue front end, a protocol processing module, a security module, a control module and a storage unit. By the control method for the tag chip, standard control, common security control and senior security control performed by the electronic tag chip is realized according to the working mode of the security mode. In the tag chip and the method, the security module integrated on the chip is utilized to ensure the communication security between the chip and a reader-writer and the security of the data stored in a chip memory; and through large-capacity memory and memory management mechanism, the capacity of providing field direct service orientating a plurality of users is realized. The chip can serve as a unique identity identification of the vehicle, and can be applied in the field of roadway traffic management.

Description

technical field [0001] The invention belongs to the technical fields of radio frequency identification (RFID) technology and the Internet of Things, and in particular relates to a high-performance, high-safety passive ultra-high frequency RFID electronic tag chip for automobiles and a corresponding control method. Background technique [0002] Radio Frequency Identification (RFID) technology is one of the six basic technologies in the field of the Internet of Things. It has the function of automatically identifying, obtaining and modifying object information, and can quickly and effectively identify and manage vehicle and driver information. [0003] If it is used as the unique identity of the car, integrated with the vehicle, and applied in the field of road traffic management, the RFID tag chip must consider the resource-based service characteristics of cross-domain and cross-business processes, and must have independent working capabilities and capabilities in each applica...
