以下、本発明の実施の形態について詳細に説明する。
図１は本発明の実施例を示す超電導磁気浮上式車両の超電導磁石の左右方向の位置の変位量の測定装置の模式図である。
この図において、１は超電導磁気浮上式鉄道のガイドウェイ、２はそのガイドウェイ１の一方の側に配置される第１の側壁、３はその第１の側壁２の裏側に配置される基準用サーチコイル、４はその第１の側壁２の裏側に配置される補正用サーチコイル、５はそのガイドウェイ１のもう一方の側に配置される第２の側壁、６はその第２の側壁５の裏側に配置される基準用サーチコイル、７はその第２の側壁５の裏側に配置される補正用サーチコイル、８は超電導磁石９を台車１０に搭載し、ガイドウェイ１を走行する超電導磁気浮上式車両、１１は基準用サーチコイル３，６及び補正用サーチコイル４，７で検出される、超電導磁石９の通過時の誘導電圧を演算する演算処理装置である。 Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 is a schematic diagram of an apparatus for measuring the amount of displacement of a superconducting magnet in a lateral direction of a superconducting magnet levitation vehicle according to an embodiment of the present invention.
In this figure, 1 is a guideway of a superconducting magnetic levitation railway, 2 is a first side wall disposed on one side of the guideway 1, and 3 is a reference side disposed on the back side of the first side wall 2. A search coil, 4 is a correction search coil disposed on the back side of the first side wall 2, 5 is a second side wall disposed on the other side of the guideway 1, and 6 is a second side wall 5 thereof. 7 is a reference search coil disposed on the back side of the second side wall 5, 7 is a search coil for correction disposed on the back side of the second side wall 5, and 8 is a superconducting magnet that travels on the guide way 1 with the superconducting magnet 9 mounted on the carriage 10. A levitated vehicle 11 is an arithmetic processing unit that calculates an induced voltage when the superconducting magnet 9 passes, which is detected by the reference search coils 3 and 6 and the correction search coils 4 and 7.

このように、第１の側壁２と第２の側壁５の裏側にサーチコイル３，４，６，７を配置するようにした。
すると、超電導磁石９とサーチコイル３，４，６，７との位置関係により、超電導磁石９の通過時のサーチコイル３，４，６，７に生ずる誘導電圧の値が変わる。つまり、超電導磁石９とサーチコイル３，４，６，７との距離に略反比例して誘導電圧の値が変わる。 Thus, the search coils 3, 4, 6, 7 are arranged on the back side of the first side wall 2 and the second side wall 5.
Then, depending on the positional relationship between the superconducting magnet 9 and the search coils 3, 4, 6, 7, the value of the induced voltage generated in the search coils 3, 4, 6, 7 when the superconducting magnet 9 passes is changed. That is, the value of the induced voltage changes in inverse proportion to the distance between the superconducting magnet 9 and the search coils 3, 4, 6, and 7.

ここで、サーチコイル３，４，６，７について説明する。
（１）同一諸元の４個のサーチコイル３，４，６，７を用意する。
（２）ガイドウェイ１の両側の側壁２，５の裏側に、鉛直方向の位置（上下位置）が超電導磁石９の鉛直方向の中心通過位置（上下位置）となるようにして各２個ずつ取り付ける。 Here, the search coils 3, 4, 6, and 7 will be described.
(1) Four search coils 3, 4, 6, and 7 having the same specifications are prepared.
(2) Two pieces are attached to the back side of the side walls 2 and 5 on both sides of the guideway 1 so that the vertical position (vertical position) is the vertical center passing position (vertical position) of the superconducting magnet 9. .

（３）それぞれの側のサーチコイルは、側壁に密着させて取り付ける基準用サーチコイルと、基準用サーチコイルよりある距離だけ側壁から遠ざけた位置にずらして取り付ける補正用サーチコイルとからなる。
（４）両側の基準用サーチコイルの出力差の半分が、超電導磁石９の左右変位量に相当する量である。両側それぞれの基準用サーチコイルと補正用サーチコイルとの出力差から求められる単位出力差あたりの距離から、この量を超電導磁石９の変位量に変換することができる。 (3) The search coil on each side includes a reference search coil that is attached in close contact with the side wall, and a correction search coil that is attached while being shifted from the side wall by a certain distance from the reference search coil.
(4) The half of the output difference between the reference search coils on both sides is an amount corresponding to the lateral displacement of the superconducting magnet 9. This amount can be converted into a displacement amount of the superconducting magnet 9 from the distance per unit output difference obtained from the output difference between the reference search coil and the correction search coil on both sides.

ここで、基準用サーチコイル３の出力はＥ11、補正用サーチコイル４の出力はＥ12、基準用サーチコイル６の出力はＥ21、補正用サーチコイル７の出力はＥ22、基準用サーチコイル３と補正用サーチコイル４との距離はｄ1 、基準用サーチコイル６と補正用サーチコイル７との距離はｄ2 として、図１を参照しながら、第１の側壁２から第２の側壁５の方向の超電導磁石９の左右変位Ｄの算出を行うと、
サーチコイル出力は、基準用サーチコイル位置付近からあまり大きく離れない（１０ｍｍ程度）範囲では、左右距離に比例であるとして差し支えないので、
Ｄ＝（Ｅ21−Ｅ11）／２×〔ｄ1 ／（Ｅ11−Ｅ12）＋ｄ2 ／（Ｅ21−Ｅ22）〕／２と求められる。 Here, the output of the reference search coil 3 is E 11 , the output of the correction search coil 4 is E 12 , the output of the reference search coil 6 is E 21 , the output of the correction search coil 7 is E 22 , and the reference search The distance between the coil 3 and the correction search coil 4 is d 1 , and the distance between the reference search coil 6 and the correction search coil 7 is d 2 , referring to FIG. When the lateral displacement D of the superconducting magnet 9 in the direction of the side wall 5 is calculated,
The search coil output can be assumed to be proportional to the left-right distance in a range that is not so far away from the vicinity of the reference search coil position (about 10 mm).
D = (E 21 -E 11) / 2 × [d 1 / (E 11 -E 12 ) + d 2 / (E 21 -E 22) ] / 2 are determined.

なお、本発明の方法によれば、車両通過速度は計算に考慮しなくてよい。超電導磁石９の上下変位は計算に考慮しなくてよい。推進コイル電流によるサーチコイルで検出される誘導電圧は計算に考慮しなくてよい。
次に、超電導磁気浮上式車両の超電導磁石の上下方向の位置の変位量測定について説明する。 According to the method of the present invention, the vehicle passing speed need not be considered in the calculation. The vertical displacement of the superconducting magnet 9 need not be considered in the calculation. The induced voltage detected by the search coil due to the propulsion coil current need not be considered in the calculation.
Next, the displacement amount measurement of the position in the vertical direction of the superconducting magnet of the superconducting magnetic levitation vehicle will be described.

図２は本発明の実施例を示す超電導磁気浮上式車両の超電導磁石の上下変位量の測定装置の模式図である。
この図において、１２は第１の基準用サーチコイル、１３は第２の基準用サーチコイル、１４は補正用サーチコイルである。
ここで、第１の基準用サーチコイル１２の出力をＥ1 、第２の基準用サーチコイル１３の出力をＥ2 、補正用サーチコイル１４の出力をＥ3 、第１の基準用サーチコイル１２と第２の基準用サーチコイル１３の中央と第２の基準用サーチコイル１３と補正用サーチコイル１４の中央との距離をｄとすれば、この場合の基準高さ（均衡変位：鎖線で表示）付近において、Ｅ2 −Ｅ1 及びＥ3 −Ｅ2 は、超電導磁石中心と基準高さとの距離Ｚに比例するとして差し支えないので、
Ｚ＝（Ｅ2 −Ｅ1 ）×ｄ／〔（Ｅ3 −Ｅ2 ）−（Ｅ2 −Ｅ1 ）〕
で求めることができる。 FIG. 2 is a schematic diagram of an apparatus for measuring the vertical displacement of a superconducting magnet of a superconducting magnetic levitation vehicle showing an embodiment of the present invention.
In this figure, 12 is a first reference search coil, 13 is a second reference search coil, and 14 is a correction search coil.
Here, the output of the first reference search coil 12 is E 1 , the output of the second reference search coil 13 is E 2 , the output of the correction search coil 14 is E 3 , and the first reference search coil 12 is output. If the distance between the center of the second reference search coil 13 and the center of the second reference search coil 13 and the correction search coil 14 is d, the reference height in this case (balance displacement: indicated by a chain line) ) In the vicinity, E 2 -E 1 and E 3 -E 2 can be assumed to be proportional to the distance Z between the center of the superconducting magnet and the reference height.
Z = (E 2 −E 1 ) × d / [(E 3 −E 2 ) − (E 2 −E 1 )]
Can be obtained.
