Embodiment 1

[0033] A radio frequency detection device for personnel passage proposed in this example, as attached figure 1 and attached figure 2 As shown: it includes a radio frequency reading and writing unit 1, a radio frequency antenna 2, a server 3, and a radio frequency tag 4, wherein the radio frequency reading and writing unit 1 further includes a decryption module 5, a communication module 6, a main controller 7 and a radio frequency controller 8; wherein,

[0034] Described radio frequency antenna 2 is made up of two radio frequency antennas that cooperate with each other, is divided into main piece and from piece, all is provided with antenna matching module and a rectangular antenna coil on every piece of radio frequency antenna; Connected to the matching modules of the two antennas, the antenna matching module is connected to the antenna coil, controlled by the radio frequency reader, the magnetic field is switched on and off, and the magnetic field energy is dissipated in the ...

Embodiment 2

[0048] This example provides a data encryption processing method of a radio frequency barrier-free personnel passage machine, wherein the structure of the radio frequency barrier-free personnel passage machine is the same as that of embodiment 1. , the following steps are performed: 1. The radio frequency controller 8 turns on the magnetic field, activates the tags in the channel, modulates and sends radio frequency signals, and performs the first round of detection.

[0049] All radio frequency tags 4 in the 2-channel magnetic field will respond after receiving the detection command, and the response will be superimposed on the magnetic field in the form of a subcarrier at the same time. At this time, there are multiple radio frequency tags 4 in the magnetic field, and the radio frequency controller 8 decodes the The response signals will conflict, resulting in code violations that cannot be successfully parsed, but the information frame headers of the tag responses are consis...

Abstract

The invention relates to a data encryption processing method for a radio frequency barrier-free personnel channel machine, and a radio frequency mechanism in the radio frequency barrier-free personnel channel machine comprises a radio frequency read-write unit, a radio frequency antenna, a server located on an upper computer, and a radio frequency tag. A main controller, a radio frequency controller, a decryption module and a communication module are arranged in the radio frequency read-write unit, the main controller is respectively connected with the radio frequency controller, the decryption module and the communication module, the communication module establishes communication with a server of an external upper computer, the radio frequency controller is connected with a radio frequency antenna, an SM7 cryptographic algorithm is arranged in the decryption module, and the communication module establishes communication with the server of the external upper computer. More than two label decryption PSAM card slots are arranged; the radio frequency tag is internally provided with a PUF physical key and an SM7 cryptographic algorithm; compared with a traditional person and certificate verification gate machine or an active card swiping type 14443A protocol card reader, on the premise that high safety and reliability are guaranteed, the recognition and reading range of the barrier-free person channel is larger, and application is more non-inductive and convenient.

Description

Technical field: [0001] The invention relates to the technical field of data encryption of radio frequency equipment, in particular to a data encryption processing method of a radio frequency barrier-free personnel channel machine with good real-time performance, high security, no sense of use experience and high convenience. Background technique: [0002] The existing radio frequency identification system mainly includes a radio frequency antenna, a read-write module for controlling radio frequency signal transmission and reception, and a radio frequency tag fixed on an item to be identified. When in use, the radio frequency antenna outputs radio frequency signals to read the radio frequency tag. The information carried on the tag is then fed back to the signal receiving circuit in the read-write module through the radio frequency antenna, and after processing the received information, the ID identification of the radio frequency tag and the object it represents can be compl...
