RFID tag housing structure, RFID tag installation structure and RFID tag communication method

Abstract

A first object of the present invention is to provide a new installation structure of RFID tags which can effectively protect the RFID tags from external pressure or impact and communicate with the outside during storage, transportation and use. The second object of the present invention is to provide a new mounting structure of an RFID tag even though the RFID tag is mounted on a conductive part such as a metal part and its surface is generally made of metal having excellent strength and durability The protective part cover is also able to communicate with the outside. A third object of the present invention is to provide a communication method using an RFID tag surrounded by a conductive member usually made of metal. Even if the RFID tag is housed in a container generally made of a conductive material such as metal having a large mechanical strength, if a magnetic flux leakage path 12 consisting only of, for example, a gap is formed in this container A, the RFID tag can leak magnetic flux. Communicates with external read / write terminal 9 as a medium.

Description

[0001] The entire disclosure of Japanese Patent Application No.2000-218443 filed on July 19, 2000; and Japanese Patent Application No.2000-233888 filed on August 2, 2000, including specification, claims, drawings and the abstract of the publication are incorporated in their entirety to claim priority under 35 U.S. C119. technical field [0002] The present invention relates to a housing structure, an installation structure and an installation method of an RFID having an antenna coil and a control part. Background technique [0003] Conventional RFID (Radio Frequency Identification) tags are broadly classified into electromagnetic induction type and electromagnetic coupling type; two types of RFID tags are designed to communicate with read / write terminals in a non-contact manner or using electromagnetic waves. [0004] The RDIF tag has an antenna coil and a control section, wherein the signal transmitted from the read / write terminal is received by the antenna coil, converted ...

AI Technical Summary

Problems solved by technology

[0013] However, due to the relatively low strength of non-conductive materials such as plastic, it is often not enough to protect RFID tags

For example, in the case where RFID tags are placed on metal manhole covers, etc., issues arise regarding the durability of RFID tags as they are continuously subjected to the weight of passing vehicular traffic, etc.
