Description

RFID-based article sorting system {ARTICLES SORTING SYSTEM BASED ON RFID}

The present invention relates to an RFID-based article sorting system.

In recent years, as industry and transportation develop and become more complicated, the cost of logistics to transport goods back to the changed place is rapidly increasing. Cases are on the rise.

In addition, as the number of e-commerce transactions using broadband networks rapidly increases, the issue of safely and promptly delivering each product to a buyer is emerging as an important key.

On the other hand, e-commerce is rapidly increasing, and according to the importance of non-face-to-face systems, consumers who deliver various items are rapidly increasing.

In order to accurately classify the delivered goods according to the rapid increase of the delivered goods, an article classification system is being applied.

The conventional article classification system reads information attached to a delivered article, classifies and loads the article by region based on the read information, and then transfers it to a delivery manager in each region.

In particular, the conventional article sorting system classifies by arranging loading means for each region, and each loading means is attached with a label indicating region information. In this case, it is common that the label is printed and attached by a printer installed in the article sorting system.

However, as the number of delivery items increases, label attachment and detachment increases exponentially, resulting in increased opportunity costs due to printer failure and damage to loading means during label attachment and detachment.

Meanwhile, the article sorting apparatus according to the embodiment of the present invention further includes an RFID reader 130 for reading information recorded in the RFID tag 102 attached to the article loading member 100 for each space 2 . can do. Specifically, the RFID reader 130 generates a carrier signal, activates the RFID tag 102 , recognizes a signal transmitted from the RFID tag 102 , reads information, and transmits it to the host computer 200 .

An identifier of the space 2 in which the RFID reader 130 is installed may be set. Accordingly, the RFID reader 130 may be connected to the host computer 200 by wire or wireless to transmit information read from the RFID tag 102 and a set identifier to the host computer 200 .

Also, the RFID reader 130 may perform an initialization function for the RFID tag 102 through interworking with the host computer 200 . Specifically, the RFID reader 130 may transmit an initialization command for initialization of the RFID tag 102 according to a request from the host computer 200 to initialize data stored in the RFID tag 102 .

The host computer 200 may perform a control function, an initialization function, a recording state verification function, and the like of the RFID writer 110 . In order to perform such a function, the host computer 200 may further include a memory 210 in which an identifier for each space 2 and an area code matched thereto are stored.

First, the control function of the RFID writer 110 transmits a predetermined operation signal generated from the host computer 200 to the communication interface 114 in response to the manager's request to turn on the RFID writer 110 for a preset time. In addition to activating the RFID tag 102 , transmission data may be transmitted and recorded to the RFID tag 102 .

The initialization function is to initialize data recorded in the RFID tag 102 , and the host computer 200 applies a signal for the initialization operation of the RFID reader 130 to the RFID reader 200 to initialize the RFID tag 102 . Stored data can be deleted.

Description of the recording status verification function, the host computer 200 receives the information and identifier read from the adjacent RFID tag 102 through the operation of the RFID reader 130, and the received identifier and information and the memory 210 The record status can be verified by comparing the data stored in the .

In addition, when there is no information read from the RFID tag 102 through the operation of the RFID reader 130 , that is, when only the identifier is received from the RFID reader 130 , the host computer 200 receives the space 2 corresponding to the identifier. An operation for operating only the RFID writer 110 installed in the . Specifically, the host computer 200 generates an operation signal for the operation of the RFID writer 110 installed in the space 2 corresponding to the identifier and applies it to the RFID writer 110 through the communication interface 114. By operating the writer 110 to transmit the transmission data, the transmission data can be recorded in the RFID tag 102 adjacent to the RFID writer 110 .

Meanwhile, the RFID writer 110 according to the embodiment of the present invention operates as the article loading member 100 is seated in the space 2 to transmit transmission data. To this end, the article sorting system according to the embodiment of the present invention is installed in each space 2 and connected to the RFID writer 110, and a detection sensor ( 140) may be further provided.

An operation of the RFID-based article sorting system having the above-described configuration will be described with reference to FIG. 3 .

As shown in FIG. 3 , the article loading member 100 is disposed in each space 2 , and the RFID tag 102 is attached to a predetermined portion of the article loading member 100 ( S300 ), and then each space According to each operation (S302) of the RFID writers 110 installed in the area adjacent to (2), each RFID writer 110 transmits transmission data (data including a local code) through an antenna, so that the RFID tag Transmission data is recorded in 102 (S304).

In the embodiment of the present invention, the operation of the RFID writer 110 is manually performed by an administrator, but is performed through the host computer 200 or through contact before attaching the RFID tag 102 or with the detection sensor 140 . This can be done through linking.

Then, each of the RFID readers 130 reads the information recorded in the RFID tag 102 through activation of the RFID tag 102, and transmits the read information and a pre-stored identifier to the host computer 200 (S306). , S308). In this case, the operation of the RFID reader 130 may be performed by the host computer 200 .

Accordingly, the host computer 200 verifies whether accurate information is recorded in the RFID tag 102 by comparing the data stored in the memory 210 with the information received from each RFID reader 130 and the identifier (S310). ).

As a result of the verification, when information is not recorded or incorrect information is recorded in any RFID tag 102 ( S312 ), the host computer 200 receives the information from the RFID reader 130 that reads information from the arbitrary RFID tag 102 . By operating the RFID writer 110 installed in the space 2 corresponding to one identifier, the transmission data is recorded again in an arbitrary RFID tag 102 (S314). In this case, the unrecorded state may mean that only the identifier is received from the RFID reader 130 .

S302∼S312를 수행할 수 있다.Although omitted in the embodiment of the present invention as described above, an initialization process may be further performed. The initialization process may be performed through the host computer 200 , that is, the host computer 200 applies a signal for an initialization operation of the RFID reader 130 to the RFID reader 200 to transmit data stored in the RFID tag 102 . deleted

S302 to S312 may be performed.
