Embodiment Construction
[0034] In order to solve the above technical problems, the general idea of the technical solution in the embodiment of the present invention is as follows:
[0035] A radio frequency information transmission device and a bidirectional amplifier, specifically, the radio frequency information transmission device includes:
[0036] A read-write antenna for receiving a first radio frequency signal including radio frequency tag information and sending the first radio frequency signal to the first input / output port or the second input / output port of the bidirectional amplifier; or for Sending a fourth radio frequency signal including information to be written into the radio frequency tag to the radio frequency tag;
[0037] The bidirectional amplifier is used to amplify the first radio frequency signal into a second radio frequency signal including radio frequency tag information through the first amplifying circuit or the second amplifying circuit and send the second radio freque...

The invention discloses a bidirectional amplifier and radio frequency tag information transmission equipment. The bidirectional amplifier can amplify an uplink signal and a downlink signal. The radiofrequency tag transmission device comprises a read-write antenna, the bidirectional amplifier and a first remote antenna. A read-write antenna, a bidirectional amplifier, a first remote antenna and areader-writer of radio frequency tag information processing equipment and a second remote antenna cooperate with each other, the radio frequency tag information processing equipment can read information from the radio frequency tag far away from the reader-writer or write the information into the radio frequency tag far away from the reader-writer; the technical problems that in the prior art, when a large radio frequency range needs to be covered, due to the fact that the radio frequency identification range of a reader-writer is small, a large number of reader-writers need to be arranged, the arrangement cost is high, and the utilization rate of the reader-writers is low are solved.
Description
technical field [0001] The invention relates to the field of communication equipment, in particular to a bidirectional amplifier and radio frequency label information transmission equipment. Background technique [0002] Electronic Rrgistration Identification Of The Motorvehicle (ERI) is also called automotive electronic ID card, automotive digital standard information source or commonly known as "electronic license plate". By reading and writing, the identification and monitoring of the vehicle can be completed automatically, non-contact, and in the running state of the vehicle. This is an extension of the passive radio frequency identification (RFID) technology of the Internet of Things in the field of intelligent transportation. [0003] When a vehicle with a vehicle-mounted electronic radio frequency tag passes through the effective reading and writing area of the reader, the vehicle-mounted electronic tag and the reader can communicate through radio frequency signals,...
