Description
Technical Field
The invention relates to the technical field of radio frequency identification, in particular to radio frequency conversion bridge equipment, a radio frequency identification system and a radio frequency data transmission method.
Background
The frequency used by the existing radio frequency identification card is different from 125KHz to 2.4GHz, different frequency bands can be selected according to different application fields and requirements, and different communication protocols and algorithms are used.
In addition, the types of card swiping terminal POS with radio frequency functions in daily life of people are also many, for example, the card swiping terminal POS is most closely combined with the life of people, the most common radio frequency terminal POS works at 13.56MHz, and the communication protocols used are Mifare, Type a, Type B, and the like.
The card swiping terminal POS machine with various different wireless radio frequency functions can be widely applied to small payment, an access control system, a public transportation system, a license identification system and the like. The communication distance is severely restricted (typically 3-10cm) due to the frequency limitations of its use. Meanwhile, the radio frequency card matched with the radio frequency card is also limited correspondingly, for example, the radio frequency card must work at 13.56MHz and use the same communication protocol.
However, with the continuous development of radio frequency technology, radio frequency identification cards with different radio frequency frequencies are emerging continuously, and many applications based on radio frequency identification can be realized on one card (some cards are in a dual-frequency mode or even a multi-frequency mode). Thus, limitations are imposed on the development of rfid cards. Especially, for the installed POS system of the card swiping terminal, it is desirable that it is compatible and communicable with a radio frequency identification card with new application (this card may work at a different radio frequency and a different radio frequency protocol from the POS terminal of the original card swiping terminal), so that the whole front-end modification or migration of the POS system of the original card swiping terminal can only be performed, which brings a huge migration cost. Meanwhile, the modified POS of the card swiping terminal is not compatible with the original card, unless two sets of POS of the card swiping terminals with different radio frequency are parallel, unnecessary cost and modification difficulty of the existing equipment are brought at the same time.

In addition, in a specific implementation scenario, due to different requirements of security level and different cost control, the encryption algorithm mentioned in the above embodiments may be partially or completely omitted, and the frequency conversion bridge device performs only the conversion of frequency and/or communication protocol. Or in some scenarios, the frequencies may be the same, i.e., F1 ≠ F2, and the communication protocols are different, i.e., P1 ≠ P2, then the frequency translation bridge device performs only the translation of the communication protocols and encryption algorithms, and so on, and will not be described in detail here.

receiving radio frequency identification data sent by a radio frequency identification card or a user identity identification terminal according to a card radio frequency processing mode;
sending the radio frequency identification data sent by the radio frequency identification card or the user identity identification terminal to a card swiping terminal according to a card swiping terminal radio frequency processing mode;
the process of transmitting the radio frequency identification data from the card swiping terminal to the radio frequency identification card or the user identification terminal specifically comprises the following steps:
receiving radio frequency identification data sent by a card swiping terminal according to a card swiping terminal radio frequency processing mode;
transmitting the radio frequency identification data sent by the card swiping terminal to a radio frequency identification card or a user identity identification terminal according to a card radio frequency processing mode;
wherein,
the card radio frequency processing mode is different from the radio frequency and/or radio frequency protocol and/or radio frequency algorithm of the card swiping terminal radio frequency processing mode;
the RF module in the card RF processing unit demodulates the RF identification data, decrypts the data by using a corresponding algorithm, encrypts the data again and transmits the data to the card swiping terminal RF processing unit, the card swiping terminal RF processing unit decrypts the data, and the RF module in the card swiping terminal RF processing unit modulates the decrypted data according to the card swiping terminal RF processing mode;
the card radio frequency processing unit and the radio frequency identification card or the user identity identification terminal also carry out mutual identity authentication, and the card radio frequency processing unit and the radio frequency identification card or the user identity identification terminal complete multiple communication, data of the multiple communication is cached in a cache region of the card radio frequency processing unit, and after a certain amount of data is reached, the card radio frequency processing unit communicates with the card swiping terminal radio frequency processing unit;
the card swiping terminal radio frequency processing unit authenticates the card swiping terminal, the card swiping terminal radio frequency processing unit completes multiple communication with the card swiping terminal, data of the multiple communication is cached in a cache region of the card swiping terminal radio frequency processing unit, and interaction with the card radio frequency processing unit is carried out after a certain amount of data is achieved.
