Abstract
The invention discloses a radio frequency identification circuit board type passive responder. A conducting hole is arranged in a circuit board and is used for conducting all layers of copper foils, a chip connecting part is arranged on the circuit board, the conducting hole is conducted with the chip connecting part, the surface of the circuit board, where the chip connecting part is arranged, fixedly covered with a protective layer with a certain thickness, a hole is formed in the protection layer at the chip connecting part, the chip connecting part concaves in the hole and exposes outside, a chip is positioned in the hole after being fixed on the chip connecting part and is not higher than the protective layer, when the radio frequency identification circuit board type passive responder enters a magnetic field, the copper foils in the circuit board receive radio-frequency signals transmitted by a reader and generate induction current for driving the chip, and the copper foils in the circuit board transmit the information in the chip to the reader. A circuit board type design is adopted in the radio frequency identification circuit board type passive responder, and the information in the chip can be transmitted to the reader for processing without antennae or power supplies, thus the structure of the traditional responder is simplified.
Description
Technical field
The present invention relates to transponder used in a kind of REID, specifically relate to a kind of transponder that combines with wiring board.
Background technology
Radio-frequency (RF) identification is a kind of contactless automatic identification technology, it is by the automatic recognition objective object of radiofrequency signal and obtain related data, identification work need not manual intervention, can work in various rugged surroundings, this technology can be discerned high-speed moving object and can discern a plurality of destination objects simultaneously, and is swift and convenient to operate.The complete radio-frequency recognition system of one cover, partly form by reader, transponder and three of application software systems, its principle of work is the radiofrequency signal that reader is launched a characteristic frequency, be positioned at and receive the radiofrequency signal that reader sends after transponder on the destination object enters magnetic field, transponder relies on the energy drives its internal circuit that induction current obtained, and the data of the destination object stored in the chip in the transponder are sent to reader, this moment, reader just received unscrambling data in regular turn, gave application software system and did corresponding processing.Radio-frequency (RF) identification can be applicable to logistics and fields such as processing, document tracking, library management, animal identification sign, motion timing, gate inhibition's control, electronic entrance ticket, the automatic charge of road are wrapped up in supplies management, the manufacturing and assembling, aviation luggage processing, mail, fast freight, can produce for the client does to customize, satisfy various requirement.Used transponder is the information carrier of radio-frequency recognition system in the REID, transponder is made up of chip, coupling original paper and antenna etc. mostly at present, chip is used to gather and store the relevant data of destination object, the coupling original paper generally is a coil etc., be used to produce induction current and drive transponder, antenna is used for the information transmission between transponder and the reader, because this structure of transponder makes the transponder volume often bigger.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of radio-frequency (RF) identification board-like passive balise of circuit, after this radio-frequency (RF) identification enters magnetic field with the board-like passive balise of circuit, need not antenna and power supply and just the information in the chip can be passed to reader and handle, and volume is little, simple in structure.
The present invention for the technical scheme that solves its technical matters and adopt is:
A kind of radio-frequency (RF) identification board-like passive balise of circuit; wiring board has two-layer at least; wiring board is provided with via; described each layer of via conducting Copper Foil; described wiring board is provided with the chip junction that is used to connect chip; described via and described chip junction are conducted; fixedly be coated with on the PCB surface at place, described chip junction and have certain thickness protective seam; described protective seam forms hole in described chip junction; outside described chip junction sinks in the described hole and is exposed to; chip is positioned at described hole and does not exceed described protective seam after being fixed in described chip junction; when this radio-frequency (RF) identification after board-like passive balise enters magnetic field with circuit; Copper Foil in the described wiring board receives the radiofrequency signal of reader emission and produces the induction current chip for driving, and the Copper Foil in the wiring board passes to reader with the information in the chip again.
The invention has the beneficial effects as follows: when this radio-frequency (RF) identification after board-like passive balise enters magnetic field with circuit, Copper Foil in the described wiring board receives the radiofrequency signal of reader emission and produces the induction current chip for driving, Copper Foil in the wiring board passes to reader with the information in the chip again, promptly this radio-frequency (RF) identification has adopted the board-like design of circuit with the board-like passive balise of circuit, need not antenna and power supply just can pass to the information in the chip reader and handle, simplified the structure of traditional transponder, because it is simple in structure, so volume is little, durable.
