Abstract

The utility model relates to the field of electronic tag equipment and particularly relates to an electronic tag reader. The electronic tag reader comprises a coupling module, a transmitting/receiving module, a control module and an interface unit, wherein the coupling module, the transmitting/receiving module and the interface unit are simultaneously connected with the control module. According to the electronic tag reader, the coupling module is used for providing energy and time sequences for tags, the transmitting/receiving module is used for detecting the working frequencies of the tags and feeding back corresponding electrical signals, and the control module is used for processing the received feedback electrical signals and changing the working frequency of the coupling module so as to adapt to the working frequencies of the overlapped tags; and all overlapped tags are identified through the matching of the working frequencies.

Description

A kind of electronic label reader

Technical field

The utility model relates to the electronic tag apparatus field, relates in particular to a kind of electronic label reader.

Background technology

Electronic tag is being commonly called as of radio frequency identification (Radio Frequency Identification); English abbreviation is RFID; It is a kind of communication technology; Can discern specific objective and read and write related data through radio signals, and need not to set up machinery between recognition system and the specific objective or optics contacts.

The RFID RF identification is a kind of contactless automatic identification technology, and it is through the automatic recognition objective object of radiofrequency signal and obtain related data, and identification work need not manual intervention, can work in various rugged surroundings.Whole rfid system has only two basic devices, is made up of a reader and a lot of transponders.

Initial transponder is meant the electronic module that can transmit information-reply information, and in recent years, because the radio-frequency technique development is swift and violent, transponder had had new saying and implication, is called intelligent label or label again.Electronic label reader carries out radio communication through antenna and label, can realize reading or write operation tag recognition sign indicating number and internal storage data.The typical electronic label reader includes high-frequency model, control module and antenna.

The frequency of operation of definition radio frequency identification system has the interior Different products that meets various criterion of frequency range of low frequency, high frequency and ultrahigh frequency at present, and the radio frequency identification system of different frequency range has different characteristic.

High frequency reader frequency of operation is 13.56MHz; Under this frequency; The inner inductor of reader can be made antenna through the mode of corrosion or printing; Inductor generally carries out work through the mode of load-modulate, just impels the voltage on the reading and writing device antenna to change through switching on and off of the pull-up resistor on the inductor, realizes with the distance sensing device aerial voltage being carried out Modulation and Amplitude Modulation; If people switch on and off through the Data Control load voltage, these data just can be transferred to read write line from inductor so.

But present high frequency reader is when reading the label that overlaps fully; The overlapping frequency of operation of label can change; The problem of each label can appear reading fully; Be easy to generate the phenomenon of skip, use extremely instability, and be unfavorable for very much making the popularization of wireless recognition technique in some field.

The utility model content

The goal of the invention of the utility model is to provide a kind of use more stable, can read the electronic label reader of overlapping label.

In order to realize the foregoing invention purpose, the novel technical scheme of this use is:

A kind of electronic label reader comprises coupling module, transceiver module, control module, interface unit; Said coupling module, transceiver module, interface unit be link control module simultaneously.

The utility model provides energy and sequential through coupling module to label; Frequency of operation and feedback corresponding electric signal through the transceiver module tags detected; Control module handle to receive the feedback electric signal, and the frequency of operation that changes coupling module is to adapt to the frequency of operation of the label after overlapping.Coupling through frequency of operation identifies each overlapping label.

Description of drawings

Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, does not constitute the improper qualification to the utility model, in the accompanying drawings:

A kind of schematic diagram that Fig. 1 provides for the utility model embodiment 1.

Embodiment

To combine accompanying drawing and specific embodiment to specify the utility model below, be used for explaining the utility model in the illustrative examples and the explanation of this utility model, but not as the qualification to the utility model.

Embodiment 1: as shown in the figure, a kind of electronic label reader is disclosed, and comprise coupling module 200, transceiver module 300, control module 100, interface unit 400; Coupling module 200, transceiver module 300, interface unit 400 be link control module 100 simultaneously.

Present embodiment provides energy and sequential through coupling module 200 to label; Frequency of operation and feedback corresponding electric signal to control module 100 through transceiver module 300 tags detected; Control module 100 is handled and is received the feedback electric signal, and the frequency of operation of the coupling module of control break simultaneously 200 is to adapt to the frequency of operation of the label after overlapping.Coupling through frequency of operation identifies each overlapping label.

More than technical scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.

Claims

1. electronic label reader is characterized in that:

Comprise coupling module, transceiver module, control module, interface unit;

Said coupling module, transceiver module, interface unit be link control module simultaneously.
