JP4435669B2 - Mounting structure of RFID tag to management object - Google Patents

Description

  The present invention relates to a structure for attaching an electronic tag storing identification information for identifying a management object to the management object. The electronic tag is used, for example, for identifying a management target object when maintaining or inspecting the management target object such as a valve or trap installed in a steam pipe or a steam plant equipment.

  The conventional attachment structure of an electronic tag to an object to be managed is such that an electronic tag storing identification information for identifying the object to be managed is suspended from the object to be managed by a wire as an attachment.

In the conventional device, the electronic tag is easily detached from the fixture, and the fixture is easily detached from the management target. Therefore, there is a problem that if the electronic tag is dropped from the management target, the management target cannot be identified. In addition, the electronic tag may come into contact with the management target due to the influence of the wind or when a person or object hits it. Therefore, when the management target is hot, such as a valve or trap installed in the steam pipe, the electronic tag is damaged by the heat of the management target, and the identification information stored in the electronic tag cannot be read. there were.

  The problem to be solved is to provide a structure for attaching an electronic tag to an object to be managed that can prevent the electronic tag from dropping off or being damaged.

  The present invention includes an electronic tag in which identification information for identifying a management object is stored, and an attachment to which the electronic tag is attached and attached to the management object. The attachment is a casing of the management object. There is an object fixing part fixed between the fastening surfaces and a tag fixing part to which the electronic tag is fixed, and the object fixing part is fixed to the management object by separating the tag fixing part from the management object. In this structure, the electronic tag is attached to the management target.

  According to the structure for attaching an electronic tag to an object to be managed according to the present invention, it is possible to prevent the electronic tag from falling off or being damaged, so that an excellent effect of being able to continue to identify the object to be managed for a long time is produced.

  In the present invention, the electronic tag is fixed to the tag fixing portion of the fixture, and the target fixing portion of the fixture is fixed between the fastening surfaces of the casing of the management target. It can be prevented from falling off, and the fixture can be prevented from falling off the management object. In addition, since the fixture is such that the tag fixing portion is separated from the management target and the target fixing portion is fixed to the management target, the electronic tag can be prevented from being damaged by the heat of the management target.

  An embodiment showing a specific example of the above technical means will be described (see FIGS. 1 and 2). FIG. 1 is a cross-sectional view showing a structure for attaching an electronic tag 2 to a vapor trap 1 as a management object, and FIG. 2 is a plan view of the electronic tag 2 and the fixture 3 of FIG. In the steam trap 1, an upper body 5 having an inlet 4 and a lower body 7 having an outlet 6 are fastened by screw connection to form a casing having a valve chamber 8 therein. The valve port 10 is automatically opened and closed by expansion and contraction.

  The fixture 3 is fixed by screwing the upper body 5 and the lower body 7 with the fixture 3 sandwiched between the fastening surface 5a of the upper body 5 and the fastening surface 7a of the lower body 7. The upper body 5 and the lower body 7 may each be provided with a flange portion, and the fixture may be fixed by fastening the fixture 3 between fastening surfaces of the flange portion with a fastening member such as a bolt. The fixture 3 is formed of a metal plate such as stainless steel or aluminum, or a thin plate of synthetic resin, etc., and has an object fixing part 3a on a part (left part) side and a tag fixing part 3b on the other part (right part) side. . The electronic tag 2 is fixed with a machine screw 12 via a washer 11 on the side (upper surface) opposite to the steam trap 1 of the tag fixing portion 3b of the fixture 3. The electronic tag 2 uses RFID (radio frequency identification) technology, and is a circuit element in which a circuit element storing identification information of the vapor trap 1 is electrically connected to an antenna element. In the fixture 3, the object fixing portion 3 a is fixed to the steam trap 1 so that the tag fixing portion 3 b is away from the steam trap 1.

  The identification information of the steam trap 1 stored in the electronic tag 2 is wirelessly transmitted to a tag reader (not shown) in a non-contact manner. Since the electronic tag 2 is fixed to the tag fixing portion 3b of the fixture 3, and the fixture 3 has the object fixing portion 3a fixed to the steam trap 1, the electronic tag 2 can be prevented from falling off the fixture 3. In addition, it is possible to prevent the fixture 3 from falling off the steam trap 1. In addition, since the fixture 3 is such that the tag fixing portion 3b is separated from the steam trap 1 and the object fixing portion 3a is fixed to the steam trap 1, the electronic tag 2 is prevented from being damaged by the heat of the steam trap 1. it can.
