JP4619752B2 - 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 a management target object such as a valve or trap installed in a steam pipe or a facility equipment of a steam plant.

  The conventional attachment structure of an electronic tag to an object to be managed is a structure in which an electronic tag storing identification information for identifying an 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. For this reason, there is a problem that when the management object is hot, such as a valve or trap installed in the steam pipe, the electronic tag is damaged by the heat of the management object, 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 falling 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 management object is installed in a steam pipe. The radiant heat is increased by the valves, traps or steam plant equipment that is used, and the electronic tag is damaged by heat. The fixture is fixed to the object fixing part and the electronic tag fixed to the management target. A tag fixing portion, an object fixing portion, and an intermediate portion extending substantially horizontally so as to be separated from the side management object between the tag fixing portion and the tag fixing portion. The object fixing part is fixed to the management object so that the horizontal distance of the object is larger than the horizontal distance between the object fixing part and the management object, and the projection surface of the management object is viewed in plan view. Tag fixed outside There is a mounting structure of the management object of the electronic tag, characterized by position.

  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 dropping off or being damaged, and therefore, an excellent effect that the object to be managed can be continuously identified over a long period of 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 to the management target, so that the electronic tag can be prevented from falling off the fixture, Moreover, it can prevent that a fixture falls out from a management target object. In addition, the object to be managed is a valve or trap installed in the steam pipe or the equipment of the steam plant that raises the radiant heat and damages the electronic tag by the heat. There is an intermediate part extending almost horizontally so as to be away from the management object on the side between the fixed parts, and the horizontal distance between the tag fixing part and the management object is managed with the target fixing part. Since the object fixing part is fixed to the management object so as to be larger than the horizontal distance between the object and the tag fixing part is located outside the projection surface of the management object in plan view. The electronic tag can be prevented from being damaged by the heat of the management object.

An embodiment showing a specific example of the above technical means will be described (see FIGS. 1 and 2). FIG. 1 is a front view showing an attachment structure of an electronic tag 2 to a vapor trap 1 as a management object, and FIG. 2 is a side view of FIG. The steam trap 1 forms a casing with a main body 5 having an inlet 3 and an outlet 4 and a lid body 6, and a lid body 6 composed of a square flange portion 7 of the main body 5 and a square flange is fastened with bolts 9. It is. The vapor trap 1 increases radiant heat and damages the electronic tag 2 with heat.

A fixture 12 is fixed to the flange portion 7 of the main body 5 with a small screw 13 via a heat insulating tube 10 on the flange portion 7 side and a washer 11 on the opposite side. The fixture 12 is formed of a metal plate such as stainless steel or aluminum, or a thin plate of synthetic resin, etc., the object fixing part 12a on the part (lower part) side, the tag fixing part 12b on the other part (upper part) side, and the object Between the fixed part 12a and the tag fixed part 12b, there is an intermediate part extending substantially horizontally so as to be separated from the side steam trap 1 . The fixture 12 may be directly fixed to the casing by welding or other means without using the heat insulating tube 10 or the washer 11. The electronic tag 2 is fixed with a small screw 15 via a washer 14 on the opposite side of the tag fixing portion 12 b of the fixture 12 from the steam trap 1. 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.

The main body 5 of the steam trap 1 has a flange portion 7 having a larger diameter than the upper portion thereof, and the fixture 12 has a horizontal distance between the tag fixing portion 12b and the steam trap 1 that is equal to the object fixing portion 12a and the steam. The object fixing portion 12a is fixed to the steam trap 1 so as to be larger than the distance in the horizontal direction from the trap 1. The tag fixing portion 12b is located outside the projection surface of the steam trap 1 in plan view. In particular, by bending the fixture 12 as shown, the horizontal distance between the tag fixing portion 12b and the steam trap 1 can be reduced in the horizontal direction between the object fixing portion 12a and the steam trap 1. It can be made larger than the distance.

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 12b of the fixture 12, and the fixture 12 has the object fixing portion 12a fixed to the steam trap 1, the electronic tag 2 can be prevented from falling off the fixture 12. In addition, the fixture 12 can be prevented from falling off the steam trap 1. Further, the fixture 12 has an intermediate portion extending substantially horizontally so as to be separated from the side steam trap 1 between the object fixing portion 12a and the tag fixing portion 12b, and the tag fixing portion 12b, the steam trap 1 and the like. Is fixed to the steam trap 1 so that the distance in the horizontal direction is larger than the distance in the horizontal direction between the object fixing portion 12a and the steam trap 1, and is outside the projection surface of the steam trap 1 in plan view. Since the tag fixing portion 12b is located , the electronic tag 2 can be prevented from being damaged by the heat of the steam trap 1.
