Abstract

The utility model discloses an RFID tag reading device capable of carrying out secondary confirmation, and particularly relates to the field of RFID tags. According to the utility model, the infrared receiver and the infrared LED lamp are added on the basis of the RFID reader-writer and the RFID tag, and as the infrared receiver can only receive one infrared LED lamp signal at a time, when the RFID reader-writer controls the tag opposite to the antenna to emit light, the current EPC number can be confirmed to be the tag opposite to the tag, namely the tag to be read, so that the rest tags are filtered. After the tag data are read, the tag data can be automatically confirmed for the second time, correct tags can be screened out, the tag data can be applied to the identification of pallet, turnover boxes and the like, and the occurrence of the phenomenon of serial reading can be prevented.

Description

RFID tag reading device capable of carrying out secondary confirmation

Technical Field

The utility model relates to the technical field of RFID tags, in particular to an RFID tag reading device capable of performing secondary confirmation.

Background

The passive RFID technology has the characteristics of non-contact and large-batch reading, and is widely applied to the fields of logistics, equipment inspection, warehouse entry and exit management and the like. The ultrahigh frequency RFID technology has the advantages of long distance, non-contact, no need of a power supply, batch reading and the like, and also because the ultrahigh frequency RFID technology can be read in batches, the ultrahigh frequency RFID technology is easy to read in series in practical application, particularly in places where goods are densely placed, so that other tags can not be read, whether the current read tag is a correct article tag or not can not be confirmed, the tag which needs to be read originally can not be read, other tags are read by mistake, and the practical application effect is far lower than expected. If manual confirmation is required after reading, the advantages of using RFID technology are lost.

Disclosure of Invention

The present utility model is directed to an RFID tag reading device capable of performing secondary verification, so as to solve the problems set forth in the background art.

In order to solve the technical problems, the utility model provides the following technical scheme: the RFID tag reading device capable of carrying out secondary confirmation comprises an RFID reader-writer and an RFID tag, wherein the RFID reader-writer is connected with an RFID antenna through a wire, an infrared receiver is arranged on the RFID antenna, and an infrared LED lamp is fixedly arranged on the RFID tag.

In a preferred embodiment, the infrared LED lamp is embedded and arranged inside the RFID tag, and a light-transmitting window is arranged on the RFID tag, so that light emitted by the infrared LED lamp is emitted at a smaller angle through the light-transmitting window.

In a preferred embodiment, the RFID antenna employs a narrow beam antenna, and the infrared receiver is matched with the infrared LED lamp, where the narrow beam antenna can reduce electromagnetic wave coverage, so that the number of tags that can be read at the same time is as small as possible, and the time for subsequent polling and confirmation by the LED is reduced.

Compared with the prior art, the utility model has the following beneficial effects:

according to the utility model, the infrared receiver and the infrared LED lamp are added on the basis of the RFID reader-writer and the RFID tag, and as the infrared receiver can only receive one infrared LED lamp signal at a time, when the RFID reader-writer controls the tag opposite to the antenna to emit light through the tag EPC number, the current EPC number can be confirmed to be the tag opposite to the tag, namely the tag to be read, so that other tags are filtered. After the tag data are read, the tag data can be automatically confirmed for the second time, correct tags can be screened out, the tag data can be applied to the identification of pallet, turnover boxes and the like, and the occurrence of the phenomenon of serial reading can be prevented.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, the utility model provides an RFID tag reading device capable of performing secondary confirmation, which comprises an RFID reader-writer 1 and an RFID tag 2, wherein the RFID reader-writer 1 is connected with an RFID antenna 4 through a wire 3, an infrared receiver 5 is arranged on the RFID antenna 4, and an infrared LED lamp 6 is fixedly arranged on the RFID tag 2.

In a preferred embodiment, the infrared LED lamp 6 is embedded in the RFID tag 2, a light-transmitting window is arranged on the RFID tag 2, and the RFID electronic tag adopts a luminous LED tag, so as to avoid the influence of visible light, and adopts an infrared LED; under the protection of the tag shell, the infrared LED lamp 6 enables the coverage range of the infrared LED lamp to be within a small angle, such as 30 degrees, through a light-transmitting window on the tag, and the specific angle can be customized according to the actual application scene. The RFID tag 2 is fixed to the outer surface of the goods or the transfer case.

In a preferred embodiment, the RFID antenna 4 adopts a narrow beam antenna, the infrared receiver 5 is matched with the infrared LED lamp 6, and the receiving device is controlled to receive only an infrared signal coming from a very small angle through the lens and the shell window of the infrared receiver 5, so that it is ensured that only an infrared signal sent from one tag can be received each time, the RFID antenna 4 adopts a narrow beam antenna, the coverage of electromagnetic waves is reduced, the number of tags which can be read simultaneously is as small as possible, and the time for subsequent polling confirmation through the LED is reduced.

The working principle of the utility model is as follows: when the RFID reader-writer 1 reads the tags, the EPC numbers of the tags are read first, all the tags are polled through the EPC numbers, each tag is controlled to emit infrared light one by one, then the infrared signals are received through the infrared receiver 5 on the RFID antenna 4, and because the infrared receiver 5 on the RFID antenna 4 can only receive infrared signals emitted by the tags in a very small angle range right in front of the antenna, when the RFID reader-writer 1 controls the tags which are right opposite to the antenna to emit light, the current EPC number can be confirmed to be the tags which are right opposite to the tags, namely the tags which need to be read, and therefore the rest tags are filtered. As shown in fig. 3, the RFID reader 1 can read EPC numbers of the RFID electronic tags 2 on 3 cargoes at the same time, but only an infrared signal of a tag on a second cargo can be received due to the fact that the antenna is opposite to the electronic tag of the second cargo, so that EPC numbers of the other two cargoes can be filtered.

Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present utility model has been described in detail with reference to the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
