磁性体の検査装置および磁性体の検査システムInspection apparatus for magnetic body and inspection system for magnetic body
　本発明は、磁性体の検査装置および磁性体の検査システムに関し、特に、検査装置本体を備える磁性体の検査装置および磁性体の検査システムに関する。 The present invention relates to a magnetic material inspection apparatus and a magnetic material inspection system, and more particularly to a magnetic material inspection apparatus and a magnetic material inspection system provided with an inspection apparatus main body.
　従来、検査装置本体を備える磁性体の検査装置および磁性体の検査システムが知られている。このような磁性体の検査装置および磁性体の検査システムは、たとえば、特開２００６－１７０７６６号公報に開示されている。 DESCRIPTION OF RELATED ART Conventionally, the test | inspection apparatus of a magnetic body provided with a test | inspection apparatus main body, and the test | inspection system of a magnetic body are known. An inspection apparatus of such a magnetic body and an inspection system of the magnetic body are disclosed, for example, in JP-A-2006-170766.
　上記特開２００６－１７０７６６号公報には、検査部と、超音波探傷器と、位置検出処理手段としてのエンコーダ出力装置とを備える、探傷装置が記載されている。上記探傷装置は、被検体の表面上を移動可能に構成されている。検査部は、超音波探傷用のプローブにマウススキャナを結合した構成となっている。プローブは、圧電素子である振動子を備えている。振動子から発生される超音波が被検体の表面に出射され、被検体により反射された超音波の反射エコーが振動子により検知される。そして、振動子により検知された検知信号が、超音波探傷器に出力される。超音波探傷器は、振動子から出力された検知信号を処理することによって探傷データを生成する。 The above-mentioned JP-A-2006-170766 describes a flaw detection apparatus including an inspection unit, an ultrasonic flaw detector, and an encoder output device as position detection processing means. The flaw detection apparatus is configured to be movable on the surface of a subject. The inspection unit has a configuration in which a mouse scanner is coupled to a probe for ultrasonic flaw detection. The probe includes a vibrator that is a piezoelectric element. The ultrasonic wave generated from the transducer is emitted to the surface of the subject, and the reflection echo of the ultrasonic wave reflected by the subject is detected by the transducer. Then, a detection signal detected by the transducer is output to the ultrasonic flaw detector. The ultrasonic flaw detector generates flaw detection data by processing the detection signal output from the transducer.
　また、上記探傷装置には、エンコーダと、エンコーダからの信号に基づいて、プローブの位置の検出処理を行うエンコーダ出力装置とが備えられている。エンコーダ出力装置は、エンコーダから出力される（マウススキャナに設けられたボールの）回転検出信号に基づいて、予め設定された基準位置からのプローブの移動距離を算出し、プローブの位置情報を超音波探傷器に出力する。すなわち、超音波探傷器では、探傷データと同時にプローブの位置情報が取得されることにより、被検体における傷等の欠陥の位置を特定することが可能に構成されている。 Further, the flaw detection apparatus includes an encoder and an encoder output device that performs processing of detecting a position of a probe based on a signal from the encoder. The encoder output device calculates the movement distance of the probe from a preset reference position based on the rotation detection signal (of the ball provided to the mouse scanner) output from the encoder, and detects the position information of the probe as an ultrasonic wave. Output to the flaw detector. That is, in the ultrasonic flaw detector, by acquiring the positional information of the probe simultaneously with the flaw detection data, it is possible to specify the position of a defect such as a flaw on the object.

　図２（ａ）に示すように、検査装置１００（後述する検知部２）は、スチールワイヤロープＷの磁界（磁束）の変化を検知するように構成されている。 As shown to Fig.2 (a), the inspection apparatus 100 (detection part 2 mentioned later) is comprised so that the change of the magnetic field (magnetic flux) of the steel wire rope W may be detected.
　磁界印加部１は、検査対象物であるスチールワイヤロープＷに対して予めＹ方向に磁界を印加し磁性体の磁化の大きさおよび方向を整えるように構成されている。また、磁界印加部１は、長尺材からなるスチールワイヤロープＷに対してＹ２方向に磁界を印加する第１磁界印加部１１ａおよび１１ｂと、Ｘ方向において、検知部２の第１磁界印加部１１ａおよび１１ｂの側とは反対側に設けられ、長尺材からなるスチールワイヤロープＷに対しＸ方向に交差する面に平行かつＹ２方向と反対方向となるＹ１方向に沿って磁界を印加する第２磁界印加部１２ａおよび１２ｂとを含む。すなわち、磁界印加部１は、長尺材の長手方向であるＸ方向と略直交する方向に磁界を印加するように構成されている。 The magnetic field application unit 1 is configured to apply a magnetic field in the Y direction in advance to the steel wire rope W which is an inspection object, and to adjust the magnitude and direction of the magnetization of the magnetic body. The magnetic field application unit 1 applies first magnetic field application units 11a and 11b for applying a magnetic field in the Y2 direction to the steel wire rope W made of a long material, and the first magnetic field application unit of the detection unit 2 in the X direction. A magnetic field is provided along the Y1 direction which is provided on the opposite side to the 11a and 11b sides and is parallel to the plane intersecting the X direction with respect to the steel wire rope W made of a long material and opposite to the Y2 direction. And 2 magnetic field application units 12a and 12b. That is, the magnetic field application unit 1 is configured to apply the magnetic field in the direction substantially orthogonal to the X direction which is the longitudinal direction of the long material.
　図２（ｂ）に示すように、検知部２は、励振コイル２１と検知コイル２２とを含む。また、励振コイル２１および検知コイル２２は、図２（ａ）および図２（ｂ）に示すように、長尺材からなる磁性体であるスチールワイヤロープＷの延びる方向を中心軸として、長手方向に沿うように複数回巻回され、スチールワイヤロープＷの延びるＸ方向（長手方向）に沿って円筒形となるように形成される導線部分を含むコイルである。したがって、巻回される導線部分の形成する面は、長手方向に略直交し、スチールワイヤロープＷはコイルの内部を通過する。また、検知コイル２２は、励振コイル２１の内側に設けられている。なお、検知コイル２２および励振コイル２１の配置はこれに限られない。 As shown in FIG. 2 (b), the detection unit 2 includes an excitation coil 21 and a detection coil 22. Further, as shown in FIGS. 2 (a) and 2 (b), the excitation coil 21 and the detection coil 22 are longitudinal directions with the steel wire rope W, which is a magnetic material made of a long material, extending as a central axis. The coil includes a wire portion wound a plurality of times along the wire and formed into a cylindrical shape along the X direction (longitudinal direction) in which the steel wire rope W extends. Therefore, the forming surface of the wound conductor portion is substantially orthogonal to the longitudinal direction, and the steel wire rope W passes through the inside of the coil. The detection coil 22 is provided inside the excitation coil 21. The arrangement of the detection coil 22 and the excitation coil 21 is not limited to this.
　励振コイル２１は、スチールワイヤロープＷの磁化の状態を励振する。具体的には、励振コイル２１に励振交流電流が流されることにより、励振コイル２１の内部において、励振交流電流に基づいて発生する磁界がＸ方向に沿って印加されるように構成されている。 The excitation coil 21 excites the state of magnetization of the steel wire rope W. Specifically, a magnetic field generated based on the excitation AC current is applied along the X direction inside the excitation coil 21 by causing the excitation AC current to flow through the excitation coil 21.
　検知コイル２２は、検査対象物であるスチールワイヤロープＷのＸ方向の磁界の変化を検知して検知信号（電圧）を出力するように構成されている。すなわち、検知コイル２２は、磁界印加部１によりＹ２方向に磁界が印加されたスチールワイヤロープＷに対して、Ｙ２方向に交差するＸ方向の磁界の変化を検知するとともに、検知したスチールワイヤロープＷのＸ方向の磁界の変化に基づく電圧を出力するように構成されている。また、検知コイル２２は、励振コイル２１によって発生する磁界の略全てが検知可能に（入力される様に）配置されている。 The detection coil 22 is configured to detect a change in the magnetic field of the steel wire rope W as an inspection object in the X direction and output a detection signal (voltage). That is, the detection coil 22 detects a change in the magnetic field in the X direction crossing the Y2 direction with respect to the steel wire rope W to which the magnetic field is applied in the Y2 direction by the magnetic field application unit 1 and detects the steel wire rope W It is configured to output a voltage based on the change of the magnetic field in the X direction. In addition, the detection coil 22 is disposed such that substantially all of the magnetic field generated by the excitation coil 21 can be detected (inputted).
　また、検知コイル２２は、２つのコイル部分である検知コイル２２ａおよび２２ｂからなる差動コイルとなっている。また、検知コイル２２は、励振コイル２１に流れる励振交流電流により発生した磁界により磁化の状態が励振されたスチールワイヤロープＷのＸ方向の磁界の変化を検知する。 The detection coil 22 is a differential coil composed of two detection coils 22a and 22b. Further, the detection coil 22 detects a change in the magnetic field of the steel wire rope W in the X direction in which the state of magnetization is excited by the magnetic field generated by the excitation AC current flowing through the excitation coil 21.
　また、スチールワイヤロープＷに欠陥（傷等）が存在する場合は、欠陥（傷等）のある部分でスチールワイヤロープＷの全磁束（磁界に透磁率と面積とを掛けた値）が小さくなる。その結果、たとえば、検知コイル２２ａが、欠陥（傷等）のある場所に位置する場合、検知コイル２２ａの検知電圧の値が検知コイル２２ｂと比較して減少するため、差動コイル（検知コイル２２全体）による検知電圧の差の値（検知信号）が大きくなる。また、検知コイル２２ｂが、欠陥（傷等）のある場所に位置する場合、検知コイル２２ｂの検知電圧の値が検知コイル２２ａと比較して減少するため、差動コイル（検知コイル２２全体）による検知電圧の差の値（検知信号）が小さくなる。また、欠陥（傷等）のない部分での検知信号は略ゼロとなる。このように、差動コイルにおいて、欠陥（傷等）の存在をあらわす明確な信号（Ｓ／Ｎ比の良い信号）が検知される。これにより、電子回路部３は、検知信号の差の値に基づいてスチールワイヤロープＷの欠陥（傷等）の存在を検出することが可能である。 When a defect (such as a flaw) is present in the steel wire rope W, the total magnetic flux (a value obtained by multiplying the magnetic field by the area by the magnetic field) of the steel wire rope W is reduced at the part having the defect (such as a flaw). . As a result, for example, when the detection coil 22a is located at a location where there is a defect (such as a flaw), the value of the detection voltage of the detection coil 22a decreases as compared to the detection coil 22b. The value (detection signal) of the difference of the detection voltage by the whole) becomes large. In addition, when the detection coil 22b is located at a location where there is a defect (such as a flaw), the value of the detection voltage of the detection coil 22b is reduced compared to the detection coil 22a, so the differential coil (the entire detection coil 22) The value of the difference between the detection voltages (detection signal) decreases. Moreover, the detection signal in the part without defects (scratch etc.) is substantially zero. Thus, in the differential coil, a clear signal (a signal with a good S / N ratio) that indicates the presence of a defect (such as a flaw) is detected. Thereby, the electronic circuit unit 3 can detect the presence of a defect (such as a flaw) of the steel wire rope W based on the value of the difference between the detection signals.
　図２（ｃ）に示すように、電子回路部３は、増幅器３１と、ＡＤ変換器３２と、ＣＰＵ３３（ＣＰＵ３３を含むマイコン）と、送信部３４とを含む。増幅器３１は、検知コイル２２から出力される検知信号（スチールワイヤロープＷのＸ方向の磁界の強さに基づく電流）を増幅し、ＡＤ変換器３２に出力する。ＡＤ変換器３２は、増幅器３１により増幅されたアナログの検知信号を、デジタルの検知信号に変換する。ＣＰＵ３３は、ＡＤ変換器３２から出力される検知信号から交流成分を取り除く処理を行い、検知信号の絶対値の変化に対応した信号（ＤＣレベル信号）に変換する同期検波整流処理を行うとともに、検知信号が所定の閾値を超えた場合に、警報信号を出力する。なお、ＣＰＵ３３は、請求の範囲の「本体側制御部」の一例である。 As shown in FIG. 2C, the electronic circuit unit 3 includes an amplifier 31, an AD converter 32, a CPU 33 (a microcomputer including the CPU 33), and a transmission unit 34. The amplifier 31 amplifies the detection signal (current based on the strength of the magnetic field in the X direction of the steel wire rope W) output from the detection coil 22 and outputs the amplified signal to the AD converter 32. The AD converter 32 converts the analog detection signal amplified by the amplifier 31 into a digital detection signal. The CPU 33 performs processing for removing an AC component from the detection signal output from the AD converter 32, and performs synchronous detection rectification processing for converting it into a signal (DC level signal) corresponding to a change in absolute value of the detection signal When the signal exceeds a predetermined threshold, an alarm signal is output. The CPU 33 is an example of the “body-side control unit” in the claims.
　また、ＣＰＵ３３は、スチールワイヤロープＷに欠陥があるか否かを判定するように構成されている。また、ＣＰＵ３３は、欠陥（傷等）の大きさを判定する機能を有している。また、ＣＰＵ３３は、検知部２（検査装置１００）の移動速度の制御等を行う。具体的には、ＣＰＵ３３は、検査装置１００を駆動するモータ１０１の駆動を制御することにより、検知部２（検査装置１００）の移動速度の制御を行う。 In addition, the CPU 33 is configured to determine whether the steel wire rope W has a defect. Further, the CPU 33 has a function of determining the size of a defect (such as a flaw). The CPU 33 also controls the moving speed of the detection unit 2 (inspection apparatus 100). Specifically, the CPU 33 controls the moving speed of the detection unit 2 (inspection apparatus 100) by controlling the driving of the motor 101 that drives the inspection apparatus 100.
　ここで、図３に基づいて、ＣＰＵ３３（図２（ｃ）参照）によるスチールワイヤロープＷの欠陥の判定方法を説明する。図３に示すように、スチールワイヤロープＷの欠陥がある位置に検知コイル２２ａ（図２（ｂ）参照）が位置する場合に、差動コイル（検知コイル２２全体）による検知電圧の差の値（検知信号）の（正側の）ピーク値がｐ１であるとする。また、欠陥がある位置に検知コイル２２ｂ（図２（ｂ）参照）が位置する場合に、差動コイル（検知コイル２２（図２（ｂ）参照）全体）による検知電圧の差の値（検知信号）の（負側の）ピーク値がｐ２であるとする。 Here, based on FIG. 3, the determination method of the defect of the steel wire rope W by CPU33 (refer FIG.2 (c)) is demonstrated. As shown in FIG. 3, when the detection coil 22a (see FIG. 2B) is located at a position where there is a defect in the steel wire rope W, the value of the difference in detection voltage by the differential coil (entire detection coil 22) It is assumed that the (positive side) peak value of (the detection signal) is p1. Also, when the detection coil 22b (see FIG. 2 (b)) is located at a position where there is a defect, the value of the difference in detection voltage (detection) by the differential coil (the entire detection coil 22 (see FIG. 2 (b))) Suppose that the (negative) peak value of the signal) is p2.
　この場合、ＣＰＵ３３は、所定の閾時間内に正側のピークおよび負側のピークの両方を検知するとともに、正側のピーク値ｐ１と負側のピーク値ｐ２との差分が所定の値以上である場合に、スチールワイヤロープＷに欠陥があると判定する。なお、所定の閾時間は、検査装置１００の速度等に基づいて、任意に設定された値である。 In this case, the CPU 33 detects both the positive peak and the negative peak within a predetermined threshold time, and the difference between the positive peak value p1 and the negative peak value p2 is greater than or equal to the predetermined value. In some cases, it is determined that the steel wire rope W is defective. The predetermined threshold time is a value arbitrarily set based on the speed of the inspection apparatus 100 or the like.
　ここで、第１実施形態では、図４に示すように、送信部３４は、検知部２（図２（ａ）参照）の検知結果に基づいて、スチールワイヤロープＷに欠陥がある場合に、ＧＰＳ４により測位された位置情報に基づき、スチールワイヤロープＷの欠陥の位置情報を表示端末５に送信するように構成されている。具体的には、ＣＰＵ３３（図２（ｃ）参照）は、スチールワイヤロープＷに欠陥があると判定した場合に、スチールワイヤロープＷの欠陥の位置情報を送信部３４により表示端末５に送信させるように構成されている。以下に、欠陥の判定における制御を詳細に説明する。なお、図４は概略図であり、説明に不要な部材は、簡略化のため、図示を省略している。 Here, in the first embodiment, as shown in FIG. 4, when the steel wire rope W has a defect based on the detection result of the detection unit 2 (see FIG. 2A), the transmission unit 34: The position information of the defect of the steel wire rope W is configured to be transmitted to the display terminal 5 based on the position information determined by the GPS 4. Specifically, when the CPU 33 (see FIG. 2C) determines that the steel wire rope W has a defect, the CPU 33 causes the transmitting unit 34 to transmit the position information of the defect of the steel wire rope W to the display terminal 5 Is configured as. The control in the determination of the defect will be described in detail below. FIG. 4 is a schematic view, and members unnecessary for the description are not shown for the sake of simplification.
　図４（ａ）に示すように、Ｘ方向において、検知コイル２２の中心（検知コイル２２ａと検知コイル２２ｂとの接続点）の中心が、ＧＰＳ４の中心に対して、Ｘ１方向側に距離Ｌ１離間しているとする。距離Ｌ１は、製造時点において予め分かっている値である。 As shown in FIG. 4A, in the X direction, the center of the center of the detection coil 22 (the connection point between the detection coil 22a and the detection coil 22b) is separated by a distance L1 in the X1 direction with respect to the center of the GPS 4. It is assumed that The distance L1 is a value known in advance at the time of manufacture.
　また、ＣＰＵ３３（図２（ｃ）参照）は、差動コイル（検知コイル２２全体）による検知電圧の差の値（検知信号）が０になるタイミング、および、検査装置１００の移動速度等に基づいて、検知コイル２２の中心と欠陥の位置との間の（Ｘ方向における）距離Ｌ２を算出する。 Further, the CPU 33 (see FIG. 2C) is based on the timing at which the value (detection signal) of the difference between the detection voltages of the differential coils (the entire detection coil 22) becomes 0, the moving speed of the inspection apparatus 100, etc. Then, the distance L2 (in the X direction) between the center of the detection coil 22 and the position of the defect is calculated.
　そして、図４（ｂ）に示すように、ＣＰＵ３３は、ＧＰＳ４が欠陥の位置に移動した時点で、ＧＰＳ４の位置情報を送信部３４により表示端末５に送信させるように構成されている。具体的には、ＣＰＵ３３は、ＧＰＳ４の移動速度に基づいて、ＧＰＳ４が距離Ｌ１－Ｌ２を移動するのに要する時間ｔ１を算出する。そして、ＣＰＵ３３は、欠陥があると判定した時間から、上記移動に要する時間ｔ１後に、ＧＰＳ４の位置情報を送信部３４により表示端末５に送信させるように構成されている。 And as shown in FIG.4 (b), CPU33 is comprised so that the positional information on GPS4 may be transmitted to the display terminal 5 by the transmission part 34, when GPS4 moves to the position of a defect. Specifically, the CPU 33 calculates the time t1 required for the GPS 4 to travel the distance L1-L2 based on the travel speed of the GPS4. The CPU 33 is configured to cause the transmitting unit 34 to transmit the position information of the GPS 4 to the display terminal 5 after the time t1 required for the movement from the time when it is determined that there is a defect.
　また、ＣＰＵ３３は、ＧＰＳ４の位置情報を送信部３４により表示端末５に送信させる際に、モータ１０１（図２（ｃ）参照）を制御して、検査ユニットＵ１を停止させるように構成されている。 The CPU 33 is configured to stop the inspection unit U1 by controlling the motor 101 (see FIG. 2C) when transmitting positional information of the GPS 4 to the display terminal 5 by the transmitting unit 34. .
　図５に示すように、表示端末５は、スチールワイヤロープＷからなる検査対象物の画像情報（たとえば図面データ）を有している。具体的には、表示端末５には、スチールワイヤロープＷ、および、スチールワイヤロープＷが用いられている建造物（本実施形態では橋９００）の画像情報を有している。スチールワイヤロープＷ、および、建造物の画像情報の各々には、座標情報（たとえば、緯度および経度の情報）が含まれている。 As shown in FIG. 5, the display terminal 5 has image information (for example, drawing data) of an inspection object made of a steel wire rope W. Specifically, the display terminal 5 includes the steel wire rope W and image information of a structure (the bridge 900 in the present embodiment) in which the steel wire rope W is used. Each of the steel wire rope W and the image information of the structure includes coordinate information (for example, information of latitude and longitude).
　ここで、本実施形態では、表示端末５は、送信部３４（図４参照）により送信されるスチールワイヤロープＷの欠陥の位置情報と、検査対象物の画像情報とに基づいて、スチールワイヤロープＷにおける欠陥の位置を検査対象物の画像５０中に識別可能に表示するように構成されている。具体的には、表示端末５の図示しないＣＰＵは、送信部３４により送信されるＧＰＳ４の情報に基づいたスチールワイヤロープＷの欠陥の位置情報と、検査対象物の画像情報とを融合することにより互いの情報を関連付け、検査対象物の画像５０中にスチールワイヤロープＷの欠陥の位置を示す印を重ね合わせて表示するように構成されている。 Here, in the present embodiment, the display terminal 5 is a steel wire rope based on the position information of the defect of the steel wire rope W transmitted by the transmission unit 34 (see FIG. 4) and the image information of the inspection object. The position of the defect in W is configured to be distinguishably displayed in the image 50 of the inspection object. Specifically, the CPU (not shown) of the display terminal 5 fuses the position information of the defect of the steel wire rope W based on the information of the GPS 4 transmitted by the transmission unit 34 with the image information of the inspection object. It is configured to associate information with each other and to superimpose and display a mark indicating the position of the defect of the steel wire rope W in the image 50 of the inspection object.
　また、ユーザが、スチールワイヤロープＷの欠陥の位置を示す印のいずれかを選択した場合、選択された欠陥の緯度および経度の情報（図５では、緯度ＸＸ度、経度ＹＹ度と表示）が画像５０中に表示される。 In addition, when the user selects any of the marks indicating the position of the defect of the steel wire rope W, the information of the latitude and longitude of the selected defect (in FIG. 5, latitude XX degree, longitude YY degree displayed) It is displayed in the image 50.

　また、欠陥の位置に塗料等によりマーキングする場合と異なり、検査対象物であるスチールワイヤロープＷを汚染せずに検査を行うことができる。また、検査対象物であるスチールワイヤロープＷの素材によっては、塗料等が付着しにくい場合がある。これに対して、ＧＰＳ４の情報に基づいて欠陥の位置情報を取得する場合には、塗料等を用いる場合に比べて容易に検査を行うことができる。 Moreover, unlike the case where marking is performed at the position of the defect with a paint or the like, the inspection can be performed without contaminating the steel wire rope W as the inspection object. Further, depending on the material of the steel wire rope W which is an inspection object, the paint or the like may be difficult to adhere to. On the other hand, when acquiring the position information of a defect based on the information of GPS4, an inspection can be easily performed compared with the case where a paint etc. are used.

The inspection apparatus 100 is configured to associate and display the position of the defect in the steel wire rope W in an image 50 of the inspection object in an identifiable manner. Thereby, the position of the defect in the steel wire rope W can be made distinguishable by the simple structure which only provides GPS4.
　また、第１実施形態では、上記のように、検査ユニットＵ１が、スチールワイヤロープＷに欠陥があるか否かを判定するとともに、スチールワイヤロープＷに欠陥があると判定した場合に、スチールワイヤロープＷの欠陥の位置情報を送信部３４により表示端末５に送信させるＣＰＵ３３を含むように、検査装置１００を構成する。これにより、欠陥の判定、および、送信部３４への指示の各々を、共通のＣＰＵ３３により行うことができる。その結果、欠陥の判定、および、送信部３４への指示の各々を、別個のＣＰＵにより行う場合に比べて、回路構成の複雑化を抑制することができるとともに、欠陥の判定から送信部３４への指示までをより速やかに行うことができる。 In the first embodiment, as described above, when the inspection unit U1 determines whether the steel wire rope W has a defect and determines that the steel wire rope W has a defect, the steel wire The inspection apparatus 100 is configured to include the CPU 33 that causes the transmitting unit 34 to transmit the position information of the defect of the rope W to the display terminal 5. As a result, each of the defect determination and the instruction to the transmission unit 34 can be performed by the common CPU 33. As a result, compared with the case where each of the determination of the defect and the instruction to the transmission unit 34 is performed by a separate CPU, the circuit configuration can be prevented from being complicated, and from the determination of the defect to the transmission unit 34 It is possible to carry out more quickly up to
