Abstract
The invention relates to a low-power RFID (radio frequency identification device) positionable passive tag and a positioning method thereof. The low-power RFID positionable passive tag comprises an RFID passive tag, a supercapacitor and a low-power LED (light-emitting diode), wherein a control circuit of the RFID passive tag is externally connected with the supercapacitor; the supercapacitor is used for storing electromagnetic wave energy sent out by a reader-writer; and the supercapacitor also supplies power to the low-power LED. The positioning method comprises the following steps: sending out a command for searching a certain tag by a reader-writer, wherein the tag command comprises a tag ID (identity); within the receiving range of the reader-writer, absorbing the electromagnetic wave energy sent out by the reader-writer by all the passive tags, and storing the electromagnetic wave energy in the supercapacitor; and if the ID number of the received tag searching command sent out by the reader-writer is in accordance with the ID number of a certain passive tag, responding to the tag searching command, supplying power to a low-power LED indicating lamp by the supercapacitor to light the LED indicating lamp. The supercapacitor and the low-power LED indicating lamp are added in the RFID passive tag, so that a low-power positionable function can be achieved.
Description
Technical field
The invention belongs to passive label detection technique field, relate to a kind of low-power consumption RFID and can locate passive label and localization method thereof.
Background technology
REID (Radio Frequency Identification, abbreviation RFID), be a kind of emerging automatic identification technology that grows up the eighties in 20th century, REID is one and utilizes radiofrequency signal to pass through Space Coupling (alternating magnetic field or electromagnetic field) to realize that contactless information transmission and the information of passing through to transmit reach the technology of identifying purpose.The present invention is transformed original simple passive label, so that read write line can find the purpose label in numerous labels, can be used in actual applications searching the commodity of particular number and need not check ID number of Commercial goods labels.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of low-power consumption RFID can locate passive label and localization method thereof.
A kind of low-power consumption RFID can locate passive label, comprises RFID passive label, super capacitor and low-power consumption LED.The external super capacitor of the control circuit of RFID passive label, super capacitor is used for the electromagnetic wave energy that the storage read-write device sends, and super capacitor is returned low-power consumption LED power supply.
Above-mentioned passive label localization method is specifically:
Read write line sends searches a certain tag command, and this tag command comprises label ID; All passive labels absorb the electromagnetic wave energy that read write line sends in the read write line range of receiving, are stored in the super capacitor; If certain passive label receives that read write line sends search in the tag command ID number and conforms to oneself, then respond this and search tag command, to the power supply of low-power consumption LED light, LED light is lighted by super capacitor.
With respect to prior art, beneficial effect of the present invention:
But realize the low-power consumption positioning function by increase super capacitor and low-power consumption LED light in the RFID passive label, this mode is exempted the trouble of seeking passive label ID number, by lighting LED light, can realize that passive label locates fast, finds this label.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, present embodiment comprises RFID passive label, super capacitor and low-power consumption LED, the external super capacitor of the control circuit of RFID passive label, and super capacitor is used for the electromagnetic wave energy that the storage read-write device sends, and super capacitor is returned low-power consumption LED power supply.Green LED is adopted in the LED bright dipping, because of people's eyes the most responsive to green.Super capacitor is selected the super capacitor of U.S. Bussmann company, and model is A1635-2R5475-R; It is 62-217B/QK2C-S5757R1R3B42Z15/2T that low-power consumption LED adopts Taiwan hundred million photoelectron incorporated company (EVERYLIGHT) models.
Search a certain tag command (comprising label ID) when read write line sends, all passive labels absorb the electromagnetic wave energy that read write line sends in this read write line range of receiving, are stored in the super capacitor.If certain passive label receives that read write line sends ID number of look-up command and conforms to oneself, then respond this look-up command, to the power supply of low-power consumption LED light, LED light is lighted by super capacitor.
Super capacitor A1635-2R5475-R design parameter:
Operating voltage: 2.5volts
Surge voltage: 3.0volts
Nominal capacitance scope: 0.47-4.7F
62-217B/QK2C-S5757R1R3B42Z15/2T, design parameter:
Colour rendering index CRI:75 (Min.)
Luminous flux: 50-65lm
Operating voltage: 2.8V-3.5V
Preposition electric current: 150mA
Take the laboratory assets management as example, each equipment of laboratory sticks this passive label, when adopting read write line to send the instruction of seeking certain label, after the label response is arranged, the LED lamp on this label is lighted, and reaches the purpose of fast searching.
