Description

本発明は、管理対象物を識別するための識別情報が記憶され管理対象物に取付けられる電子タグ装置に関する。本発明の電子タグ装置は、例えば蒸気配管に設置されるバルブやトラップ、あるいは蒸気プラントの設備機器等の管理対象物を保守・点検するときに管理対象物を識別するために用いられる。   The present invention relates to an electronic tag device in which identification information for identifying a management object is stored and attached to the management object. The electronic tag device of the present invention is used, for example, for identifying a management object when maintaining or inspecting a management object such as a valve or trap installed in a steam pipe or a facility device of a steam plant.

従来の電子タグ装置は、管理対象物を識別するための識別情報が記憶された電子タグと、電子タグを管理対象物に取付ける取付具とを有するものである。   A conventional electronic tag device has an electronic tag in which identification information for identifying a management object is stored, and a fixture for attaching the electronic tag to the management object.

上記従来の電子タグ装置は、管理対象物を識別するための識別情報が得られるだけであり、管理対象物の温度の高低が判らない問題があった。管理対象物の温度の高低が判ると火傷予防に役立つばかりでなく、例えば蒸気トラップの場合は、低温であれば排水不能あるいは排水不足の状態にあると判定できる。蒸気トラップが排水不能あるいは排水不足の状態に陥ると、一次側に復水が滞留してウォータ・ハンマが発生したり、蒸気使用機器の運転効率が低下したり機器が破壊されたりするので、温度の高低を判別することは極めて肝要なことである。
特開２００３−８３８４９ The above-described conventional electronic tag device only has identification information for identifying a management object, and has a problem that the temperature level of the management object cannot be determined. Knowing the level of the temperature of the management object not only helps prevent burns, but in the case of a steam trap, for example, if the temperature is low, it can be determined that drainage is impossible or drainage is insufficient. If the steam trap cannot be drained or is not drained sufficiently, condensate will accumulate on the primary side, causing water and hammer, reducing the operating efficiency of steam-using equipment, and destroying the equipment. It is extremely important to discriminate between high and low.
JP 2003-83849 A

解決しようとする課題は、管理対象物の温度の高低を判別できる電子タグ装置を提供することである。   The problem to be solved is to provide an electronic tag device capable of determining the temperature level of a management target.

本発明の電子タグ装置は、管理対象物を識別するための識別情報が記憶された電子タグと、当該電子タグが取付けられ管理対象物に取付けられる取付具とを有するものにおいて、管理対象物の温度に応じて変形する温度応動部材で取付具を形成し、取付具は管理対象物に固定される対象物固定部が管理対象物に固定され、電子タグが固定されるタグ固定部が低温時に管理対象物に近づき高温時に管理対象物から遠ざかる自由端とされたことを特徴とする。   An electronic tag device according to the present invention includes an electronic tag in which identification information for identifying a management object is stored, and a fixture to which the electronic tag is attached and attached to the management object. A fixture is formed by a temperature responsive member that deforms according to temperature, and the fixture is fixed to the management target with the target fixing portion fixed to the management target, and the tag fixing portion to which the electronic tag is fixed is at a low temperature. It is characterized by being a free end that approaches the management object and moves away from the management object at a high temperature.

本発明の電子タグ装置は、管理対象物を識別するための識別情報が得られるだけでなく、管理対象物の温度の高低を判別できるという優れた効果を生じる。   The electronic tag device according to the present invention not only obtains identification information for identifying a management object, but also produces an excellent effect that the temperature of the management object can be determined.

本発明は、管理対象物の温度に応じて変形する温度応動部材で取付具を形成し、取付具は管理対象物に固定される対象物固定部が管理対象物に固定され、電子タグが固定されるタグ固定部が低温時に管理対象物に近づき高温時に管理対象物から遠ざかる自由端とされたものである。そのため、取付具の自由端が管理対象物に近づいていれば低温であると判別でき、取付具の自由端が管理対象物から遠ざかっていれば高温であると判別できる。   The present invention forms a fixture with a temperature-responsive member that deforms according to the temperature of the management object, and the fixture is fixed to the management object with an object fixing portion fixed to the management object, and the electronic tag is fixed The tag fixing portion is a free end that approaches the management object at a low temperature and moves away from the management object at a high temperature. Therefore, it can be determined that the temperature is low if the free end of the fixture is close to the management object, and it can be determined that the temperature is high if the free end of the fixture is far from the management object.

上記の技術的手段の具体例を示す実施例を説明する（図１と図２参照）。図１は管理対象物としての蒸気トラップ１へ電子タグ装置を取付けた正面図であり、図２は図１の平面図である。蒸気トラップ１は入口３と出口４を有する本体５と蓋体６とでケーシングを形成し、本体５の四角状のフランジ部７と四角状のフランジから成る蓋体６をボルト９で締結したものである。   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 in which an electronic tag device is attached to a steam trap 1 as a management object, and FIG. 2 is a plan view of FIG. The steam trap 1 forms a casing with a 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 body 5 and a square flange is fastened with bolts 9. It is.

本体５のフランジ部７に座金１０を介して小ネジ１１で取付具１２を固定する。取付具１２はバイメタルや形状記憶合金の薄板から成る温度応動部材で形成され、一端（右端）側に対象物固定部１２ａを、他端（左端）側にタグ固定部１２ｂを有する。取付具１２は座金１０を介さずに溶接やその他の手段によりケーシングに直接固定してもよい。取付具１２のタグ固定部１２ｂの蒸気トラップ１とは反対側に座金１３を介して電子タグ２を小ネジ１４で固定する。電子タグ２はＲＦＩＤ（無線周波数識別）技術を用いたもので、アンテナ素子に蒸気トラップ１の識別情報を記憶した回路素子を電気的に接続したものである。   A fixture 12 is fixed to the flange portion 7 of the main body 5 with a machine screw 11 via a washer 10. The fixture 12 is formed of a temperature-responsive member made of a thin plate of bimetal or shape memory alloy, and has an object fixing portion 12a on one end (right end) side and a tag fixing portion 12b on the other end (left end) side. The fixture 12 may be directly fixed to the casing by welding or other means without using the washer 10. The electronic tag 2 is fixed with a small screw 14 via a washer 13 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.

電子タグ２に記憶された蒸気トラップ１の識別情報は無線により非接触で図示しないタグ読取装置に伝達される。蒸気トラップ１が正常に復水を排出していれば、蒸気トラップ１が高温であるから、取付具１２は破線で示すように自由端であるタグ固定部１２ｂが下方に屈曲して蒸気トラップ１から遠ざかる。蒸気トラップ１が排水不能あるいは排水不足の状態に陥ると、蒸気トラップ１が低温になるので、取付具１２は実線で示すように偏平となり蒸気トラップ１に近づく。   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. If the steam trap 1 normally discharges the condensate, the steam trap 1 is hot, so that the fixture 12 has a tag fixing portion 12b which is a free end bent downward as shown by a broken line, and the steam trap 1 Keep away from. If the steam trap 1 falls into a state where drainage is impossible or insufficient, the steam trap 1 becomes low temperature, and the fixture 12 becomes flat as shown by the solid line and approaches the steam trap 1.
