The visual passive RFID electronic tag 100 according to the embodiment of the present invention includes an antenna 110 and an RFID chip 120, and the antenna 110 is configured to receive a radio frequency signal from a reader/writer and send a feedback radio frequency signal to the reader/writer, similar to the existing passive RFID electronic tag 100. The RFID chip 120 is configured to respond to an operation instruction in the received radio frequency signal, and convert the response result into a radio frequency signal for feedback and sending back to the reader. For example, the RFID chip 120 is configured to respond to a radio frequency signal received from the reader/writer to pair identity information stored in the RFID chip 120, so as to obtain a pairing result, and convert the pairing result into a radio frequency signal for feeding back to the reader/writer; or write new information or modify information in the RFID chip 120 according to the received radio frequency signal, thereby completing the change of the specified information, and the like.
In addition to the above, the visual passive RFID tag 100 according to the embodiment of the present invention further includes a display module 130, where the display module 130 includes a control unit 131 for generating data information and a display unit 132 for displaying the data information. The display unit 132 displays an indicator or a display screen, such as a physical device like a light emitting diode, an organic electroluminescent display, a plasma, a liquid crystal, an electrophoretic display, or a discharge tube; contains fluorescent agent and diphenyl anthracene electrochemical substance; luciferase bioluminescent substances and the like.

The display module 130 is coupled with an antenna so that power can be supplied directly or indirectly through the antenna.
The visual passive RFID tag 100 according to an embodiment of the present invention will be described in detail in a specific embodiment with reference to the drawings, but it should be understood that the following embodiment is only for illustrative purposes and is not intended to limit the present invention.
First embodiment
As shown in fig. 1, in this embodiment, the control units 131 of the RFID chip 120 and the display module 130 are respectively connected to two ends of the antenna 110, so that the RFID chip 120 and the display module 130 are respectively powered by the radio frequency energy carried in the radio frequency signal received by the antenna 110 from the reader/writer, thereby driving the normal operation of the two. In this case, the antenna 110 is equivalent to a current source, the display module 130 and the RFID chip 120 are connected in parallel and then connected to the current source, and the display module 130 and the RFID chip 120 are independent from each other in terms of power supply. Meanwhile, the RFID chip 120 receives a radio frequency signal directly from the antenna 110 and responds to the radio frequency signal, and for example, sends back a radio frequency signal related to the pairing result to the reader through the antenna 110, so that the pairing result can be displayed on the reader.
In the present embodiment, the control unit 131 of the display module 130 generates data information according to the radio frequency signal received by the antenna 110, for example, when the potential difference generated by the radio frequency signal received by the antenna 110 exceeds a preset threshold voltage, the control unit 131 may generate data information based on this, for example, instruct the display indicator to light, thereby prompting the operator that the tag has responded to the operation signal sent by the reader/writer. However, this display method has a disadvantage that, in the display, as long as the energy received by the display module 130 is enough, the display can be performed, that is, after the reader/writer sends an operation signal, a plurality of electronic tags 100 may be displayed simultaneously, but only one of the electronic tags 100 is matched, so that the display method can only screen a part of the electronic tags 100, and then perform final confirmation by other methods, such as voice prompt, etc.
Fig. 2 shows a preference of the present embodiment, in which the RFID chip 120 generates a display enable signal according to the pairing result, for example, generates the display enable signal when the pairing is successful; and sends the display enable signal to the control unit 131 to control the display of the display unit 132, for example, the control unit 131 only receives the display enable signal to instruct the display unit 132 to display, regardless of whether the potential difference generated by the radio frequency signal exceeds the threshold voltage of the control unit 131. With this arrangement, the displayed electronic tag 100 is unique and definitive. Of course, the control unit 131 may be connected to the RFID chip 120 at this time, and generate data information for the display unit 132 to display according to the pairing result generated by the RFID chip 120.
In the specific implementation process of the present invention, various display modes may be adopted, for example, the display mode may be only the display mode shown in fig. 1, that is, the display mode may be displayed as long as the threshold voltage is exceeded; or the display mode in fig. 2 only, that is, the display mode is displayed only when the display enable signal is received; or a combination of the above two ways, that is, the two ways are satisfied simultaneously, and then the display unit 132 may be one or more, for example, the display indicator and the display screen operate simultaneously.
Second embodiment
The second embodiment is an improvement of the power supply method in the first embodiment, and the other embodiments are the same. In the visual passive RFID electronic tag 100 according to the second embodiment, as shown in fig. 3, the antenna 110 includes a first antenna 111 and a second antenna 112, wherein the RFID chip 120 is connected to the first antenna 111, and the display module 130 is connected to the second antenna 112 through the control unit 131. Thus, the RFID chip 120 supplies power through the radio frequency signal received by the first antenna 111, and receives the radio frequency signal from the reader/writer through the first antenna 111 and transmits a feedback radio frequency signal to the reader/writer. In addition, the display module 130 is powered by the rf signal received by the second antenna 112. In this embodiment, the RFID chip 120 and the display module 130 are respectively powered by the first antenna 111 and the second antenna 112, which are independent of each other, and compared with the first embodiment, the power of the antenna can be reduced, and the power supply process is more stable.
In addition, in the specific implementation process of this embodiment, various display modes may still be adopted, and although only one of them is shown in fig. 3, that is, the display mode may be performed as long as the threshold voltage is exceeded, improvements or substitutions may also be performed on the basis, for example, as shown in fig. 4, the display mode may be performed only when the display enable signal is received; or a combination of the above two ways, that is, the two ways are satisfied simultaneously, and then the display unit 132 may be one or more, for example, the display indicator and the display screen operate simultaneously.
Third embodiment
As shown in fig. 5, in this embodiment, the RFID chip 120 is connected to the antenna 110 and the display module 130, respectively. On one hand, the RFID chip 120 performs its own power supply by the radio frequency signal received by the antenna 110, and transmits and receives the radio frequency signal by the antenna 110; on the other hand, the RFID chip 120 is further provided with a power output port connected to the display module 130, so as to distribute a part of the potential difference provided by the radio frequency signal to the display module 130, and when the distributed potential difference is large enough, the display module 130 can be driven to operate. In this power supply method, only the RFID chip 120 is connected to the antenna 110, and the display module 130 is supplied with power through the RFID chip 120. Of course, the control unit 131 may be connected to the RFID chip 120 at this time, and generate data information for the display unit 132 to display according to the pairing result generated by the RFID chip 120.
In the visual manner of this embodiment, various display manners can still be adopted, for example, display can be performed as long as the threshold voltage is exceeded; or the display can be performed only when the display enabling signal is received; or a combination of the above two ways, that is, the two ways are satisfied simultaneously, and then the display unit 132 may be one or more, for example, the display indicator and the display screen operate simultaneously.
Fourth embodiment
As shown in fig. 6, the display module 130 and the RFID chip 120 are connected in series and then connected to two ends of the antenna 110, so in this power supply mode, the antenna 110 serving as a current source simultaneously supplies power to the display module 130 and the RFID chip 120, and at this time, only when the potential difference provided by the antenna 110 exceeds the sum of the operating voltages of the display module 130 and the RFID chip 120, the display module 130 and the RFID chip 120 can normally operate, so the antenna 110 with higher power is required in this embodiment. In addition, the RFID chip 120 still transmits and receives radio frequency signals via the antenna 110 for polling and/or updating operations. Of course, the control unit 131 may be connected to the RFID chip 120 to generate data information for the display unit 132 to display according to the pairing result generated by the RFID chip 120
Fig. 7 shows a modification of the electronic tag 100 shown in fig. 6, and as shown in fig. 7, the display module 130 includes a first display module 130 and a second display module 230, and the second display module 230 also includes a control unit 231 and a display unit 232, wherein the first display module 130 and the second display module 230 are connected to the antenna 110 and the RFID chip 120, respectively. Thus, the antenna 110 as a current source simultaneously supplies power to the first and second display modules and the RFID chip 120, and the first and second display modules and the RFID chip 120 can normally operate only when the potential difference provided by the antenna 110 exceeds the sum of the operating voltages of the two display modules and the RFID chip 120. In this way, a variety of visual cues may be provided to the operator.
In the visual manner of this embodiment, various display manners can still be adopted, for example, the display module 130 can display only when the threshold voltage is exceeded; or the display can be performed only when the display enabling signal is received; or a combination of the above two ways, that is, the two ways are satisfied simultaneously, and then the display unit 132 may be one or more, for example, the display indicator and the display screen operate simultaneously.
In the process of carrying out electronic identity recognition on the visual passive RFID electronic tag according to the embodiment of the invention, firstly, a radio frequency signal is received from a reader-writer through an antenna, wherein the radio frequency signal comprises an operation instruction and carries energy, so that the antenna can be used as a current source for other parts in the electronic tag to work. Then, the RFID chip responds to the received radio frequency signal to pair the internally stored identity information to obtain a pairing result, on one hand, the pairing result needs to be fed back to the reader-writer, so that the RFID chip converts the pairing result into a radio frequency signal and sends the radio frequency signal back to the reader-writer through antenna feedback, and an operator can know the pairing result; on the other hand, the RFID chip can generate data information based on the pairing result and send the data information to the display module for the display module to display, and/or generate a display enabling signal based on the pairing result and send the display enabling signal to the display module to control whether the display unit can display or not. And then, the antenna feeds back the radio-frequency signal related to the pairing result to the reader-writer, and meanwhile, the control unit of the display module generates data information based on the pairing result and/or the display enabling signal and displays the data information through the display unit, so that visual prompt is provided for an operator, and the operator can find the electronic tag at the first time.
The various visual passive RFID tags 100 described above may be used in a variety of applications, for example, the visual passive RFID tags 100 according to embodiments of the present invention may be disposed on a fiber optic plug of a fiber optic cable. When a reader-writer wants to find an appointed or matched optical fiber plug in a plurality of optical fiber plugs on an optical distribution frame, firstly, the reader-writer sends a radio frequency signal containing a query instruction to search; after finding the specified or matched optical fiber plug, the visual passive RFID tag 100 arranged in the optical fiber plug sends a feedback radio frequency signal to the reader-writer, and at the same time, the display unit of the electronic tag 100 starts to work, including the display indicating device is turned on and/or the display screen starts to display. Therefore, an operator can find the optical fiber plug matched with the optical fiber plug at a glance from the plurality of optical fiber plugs, so that the process of searching again is omitted, the operation is simplified, and the efficiency is improved.
As can be seen from the above, the display module is arranged in the visual passive RFID tag according to the embodiment of the present invention, so that an intuitive visual prompt can be provided for an operator during the process of identity recognition and information update. In addition, the display module is directly or indirectly powered through the antenna, so that additional energy storage equipment is not needed, the design of the electronic tag is simplified, and the space is saved. In addition, the display module can be displayed as an indicator, and can also display detailed information related to the pairing result, so that the display content is rich and various. In addition, the display of the display module can be controlled by the RFID chip transmitting a display enable signal, so that the display of the display module can be unique and definite.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
