Description
Technical Field
The invention relates to the technical field of UHF (ultra high frequency) readers, in particular to a UHF reader capable of automatically adjusting power consumption.
Background
Radio Frequency Identification (RFID) is a wireless communication technology that can identify a specific object and read and write related data by radio signals without establishing mechanical or optical contact between the identification system and the specific object. The radio signal is used to transmit data from the tag attached to the article by means of an electromagnetic field modulated at a radio frequency to automatically identify and track the article. Some tags can obtain energy from the electromagnetic field emitted by the identifier during identification, and do not need a battery; there are also tags that have their own power source and can actively emit radio waves (electromagnetic fields tuned to radio frequencies). The tag contains electronically stored information that can be identified within a few meters. Unlike bar codes, radio frequency tags need not be in the line of sight of the identifier, but can be embedded within the tracked object.
Radio frequency identification technology is used in many industries. By attaching the tag to a vehicle in production, the manufacturer can track the progress of the vehicle on the production line. The warehouse may track the location of the drugs. The radio frequency tag can also be attached to livestock and pets, so that the livestock and the pets can be positively identified (positive identification means that a plurality of livestock are prevented from using the same identity). The RFID identification card can allow employees to enter a locked building, and the RFID transponder on the automobile can also be used to collect fees on toll sections and parking lots.
However, the existing hand-held UHF reader-writer can not well adjust the running power, the power consumption of the device is large, and the standby time is short.
Disclosure of Invention
In order to solve the problems, the invention adopts the following technical scheme:
the UHF reader-writer capable of automatically adjusting power consumption comprises a UHF reader-writer module, wherein the UHF reader-writer module is connected with a power adjusting circuit, the power adjusting circuit comprises a power supply, a controller, a radio frequency power amplifier and an antenna, the controller, the radio frequency power amplifier and the UHF reader-writer module are electrically connected with the power supply, the controller is in communication connection with the UHF reader-writer module, and the radio frequency power amplifier is electrically connected with the antenna.
By further illustration, the controller comprises a tag size pre-estimating module, and the tag size pre-estimating module adjusts the operating power of the UHF reader module according to the size of the tag.
Compared with the prior art, the invention has the following advantages:
the invention has simple structure, can well adjust the running power according to the requirement through the controller, greatly reduces the power consumption and improves the standby time.
