Description

RFID tag receiving device {DEVICE FOR ACCEPTING RFID TAG}

The present invention relates to a device for receiving an RFID tag, and more particularly, to locate the RFID tag as close as possible to the center of a pipe-shaped material of various shapes provided with metal or synthetic resin. It is related to the RFID tag receiving device that can increase the recognition rate of the RFID tag against the shielding or interference of radio waves by maximum separation from the side.

In general, RFID (Radio Frequency Identification) refers to a technology for recognizing information without contact by using radio waves.

The RFID includes an RFID tag consisting of an integrated circuit and an antenna and an RFID reader for recognizing and storing information stored in the integrated circuit of the RFID tag. The RFID tag is located within a predetermined distance (recognition range of the RFID reader). When located, it is implemented in such a way that the RFID reader recognizes the information of the RFID tag.

The RFID technology may be classified into passive RFID, semi passive RFID, and active RFID according to where power is used.

Here, the passive RFID means that the RFID tag does not have a built-in power supply, but recognizes information of the RFID tag only by the power of the RFID reader, and is the most popular RFID method due to the low production cost of the RFID tag. .

In addition, the semi-passive RFID (Semi passive) RFID is a power supply is built in each of the RFID tag and the RFID reader, the power for recognizing the information of the RFID tag in the RFID tag, the power for communication between the RFID tag and the RFID reader is RFID reader It is provided by, and is an RFID method used in expressway toll collection system, which is typically called 'high pass'.

In addition, the active RFID means that the power is embedded in the RFID tag so that the RFID tag supplies all the power for the recognition of the information of the RFID tag and the communication between the RFID tag and the RFID reader.

Recently, RFID technology is being used in a wide range of fields such as manpower management, payment systems, management of large industrial materials, and complementary systems, and is attracting attention as an alternative to the bar codes used in the past.

In particular, the RFID method is also used for material management such as receipt and delivery of large tubular materials installed in large waterway construction and transport pipe installation construction.
