Description
Technical field
The utility model relates to label technique fields, and in particular to a kind of RFID label tag with ena-bung function.
Background technique
RFID (radio frequency identification, Radio Frequency Identification) technology is a kind of contactless automatic
Identification technology.It passes through radiofrequency signal automatic identification target object and obtains related data, and identification work is made without manual intervention
For the wireless version of bar code, RFID technique has waterproof, antimagnetic, high temperature resistant, long service life, reading not available for bar code
Take distance is big, data can encrypt, storing data capacity is bigger on label, the change of storage information freely the advantages that, application will
Revolutionary variation is brought to industries such as retail, logistics.
The basic functional principle of RFID technique is: the radiofrequency signal of specific frequency is sent by transmitting antenna by reader,
When electronic tag enter effective working region when generate induced current, thus obtain energy, electronic tag is activated so that electronics
Label sends itself encoded information by built-in rf antenna；The receiving antenna of reader is received to be sent out from electronic tag
The modulated signal sent is transmitted to reader signal processing module through antenna adjustments device, by effective information after demodulated and decoding
It send to background host computer system and carries out relevant processing；Host system identifies the identity of the label according to logical operation, for difference
Setting make corresponding processing and control, the final command signal control reader that issues completes corresponding read-write operation.
Physical support of the electronic tag (RFID label tag) as electronic code, mainly by RFID antenna coil and RFID core
Piece composition.The form that existing RFID label tag is generally used RFID antenna coil and RFID chip is directly connected to, i.e. RFID mark
Label are constantly in the effective status of state to be triggered.However in certain special applications, RFID label tag is such as installed into object
In the transmission rail for flowing Transmission system, and certain keys are reached using the logistics trolley that RFID label tag is run as transmission rail
When whether can continue to the differentiation label to advance at point (at safety door or transition), it is constantly in effectively without RFID label tag
State, and need that it is carried out effectively to control with invalid state with ena-bung function.
Utility model content
The utility model provides a kind of RFID label tag with ena-bung function, solution be existing RFID label tag be in always to
The effective status of triggering state, without having the problem of ena-bung function.
To solve the above problems, the utility model is achieved through the following technical solutions:
RFID label tag with ena-bung function, including label body, the label body be equipped with RFID antenna coil and
RFID chip, RFID antenna coil are connect with RFID chip；It is except that the label body is also further provided with electronics
Switch and control chip；Electronic switch is serially connected between RFID antenna coil and RFID chip；Control the input terminal of chip and outer
Portion controls signal connection, and the control terminal of the output end and electronic switch that control chip connects.
In above scheme, RFID antenna coil, RFID chip, electronic switch and control chip are printed in label body.
In above scheme, the external control signal is voltage signal.
Compared with prior art, the utility model adds control chip on the basis of conventional RFID tag to realize RFID
The ena-bung function of label enables RFID label tag under control of the control system in effective or invalid state, to meet difference
The different demands of application scenarios.
Detailed description of the invention
Fig. 1 is the functional block diagram of the RFID label tag with ena-bung function.
Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, below in conjunction with specific example, and join
According to attached drawing, the utility model is further described.
Referring to Fig. 1, a kind of RFID label tag with ena-bung function, including label body, and be arranged in label body
RFID antenna coil, RFID chip, electronic switch and control chip.In RFID antenna coil and RFID chip via electronic switch
It is connected.The input terminal of control chip is connect with external control signal, which is voltage signal.Control chip
The connection of the control terminal of output end and electronic switch.In view of the requirement of label miniaturization, RFID antenna coil, RFID chip, electricity
Sub switch and control chip are printed in label body.
Below by taking logistics transportation trolley as an example, the working principle of the utility model is illustrated:
By with output contact RFID label tag be arranged on logistics transportation track, and the front of this section of track be fire window or
Points etc..Reader is mounted on logistics trolley, and logistics trolley is walked on logistics transportation track with reader.Work as object
When flowing trolley arrival RFID label tag position, reader sends the radiofrequency signal of specific frequency.Under normal condition, due to logistics
The fire window of small front side is not turned off or points do not disconnect, therefore logistics trolley is without stopping.At this point, external control letter
The control signal of normal condition number is issued to chip is controlled, control chip enables electronic switch remain off, RFID antenna line
Circle is not connected to RFID chip, and RFID label tag is in invalid state, cannot be triggered as normal, and the reader of logistics trolley can not be received
To RFID label tag return electronic code, logistics trolley normal through.When fire or transition occurs, if logistics trolley is direct
Advance, it may occur that the safety accident fallen, therefore external control signal issues the control signal of abnormality to controlling core
Piece, control chip enable electronic switch be closed, and RFID antenna coil is connected to RFID chip, and RFID label tag is in effective status, and
It can be triggered as normal, the reader of logistics trolley can be normally received the electronic code of RFID label tag return, and logistics trolley stops
Only.
It should be noted that although the above embodiment described in the utility model be it is illustrative, this is not to this
The limitation of utility model, therefore the utility model is not limited in above-mentioned specific embodiment.The utility model is not being departed from
In the case where principle, the other embodiment that all those skilled in the art obtain under the enlightenment of the utility model is accordingly to be regarded as
Within the protection of the utility model.
