The plurality of second reflectors 28 are provided on the second surface 10b up to the same height as the lower end of the car 7 when the car 7 is at its highest position.
　例えば、エレベーターシステム１において、制御盤９は、制御ケーブル１０を介してかご７からかご呼び登録の情報を受信する。制御盤９は、巻上機５を回転させる。主ロープ６は、巻上機５の回転に追従して移動する。かご７と釣合おもり８とは、主ロープ６の移動に追従して互いに反対方向に昇降する。制御ケーブル１０の他端は、かご７の昇降に追従して上下方向に移動する。制御ケーブル１０の中間部における折り返し部分の位置は、制御ケーブル１０の他端の移動に追従して上下に変化する。 For example, in the elevator system 1 , the control panel 9 receives car call registration information from the car 7 via the control cable 10 .

The other end of the control cable 10 moves vertically as the car 7 moves up and down. The position of the folded portion at the intermediate portion of the control cable 10 changes up and down following the movement of the other end of the control cable 10 .
　エレベーターシステム１の保守員は、携帯端末２４に対して点検操作を行う。この場合、携帯端末２４は、遠隔監視装置２５に起動信号を送信する。遠隔監視装置２５は、携帯端末２４からの起動信号に基づいて、照明ユニット２１に電力を供給する。照明ユニット２１は、当該電力の一部を利用して点灯する。照明ユニット２１は、電源線２３を介して当該電力の他部をカメラ２２に供給する。 The maintenance staff of the elevator system 1 performs inspection operations on the mobile terminal 24. In this case, the mobile terminal 24 transmits an activation signal to the remote monitoring device 25 . The remote monitoring device 25 supplies power to the lighting unit 21 based on the activation signal from the mobile terminal 24 . The lighting unit 21 lights using part of the electric power. The lighting unit 21 supplies the other part of the power to the camera 22 via the power line 23 .
　照明ユニット２１は、電力の供給を受けることで点灯する。カメラ２２は、電力の供給を受けることでかご７よりも下方に存在する制御ケーブル１０の画像を撮影する。例えば、カメラ２２は、通常運転の状態でかご７が最下部から最上部まで移動する際に、制御ケーブル１０が写る複数の画像を撮影する。また、カメラ２２は、通常運転の状態でかご７が最上部から最下部まで移動する際に、制御ケーブル１０が写る複数の画像を撮影する。 The lighting unit 21 is lit by receiving power supply. The camera 22 captures an image of the control cable 10 below the car 7 by being supplied with power. For example, the camera 22 captures multiple images of the control cable 10 as the car 7 moves from the bottom to the top in normal operation. In addition, the camera 22 takes a plurality of images of the control cable 10 when the car 7 moves from the top to the bottom in normal operation.
　制御ケーブル１０が正常な状態である基準姿勢である場合、制御ケーブル１０の第１面１０ａのうち折り返し部分よりも制御盤９の側の部分は、カメラ２２の側を向く。この状態において、制御ケーブル１０の折り返し部分よりも制御盤９の側に取り付けられ、かつかご７よりも下方に位置する第１反射材２７は、カメラ２２が撮影する画像における規定の範囲に写る。制御ケーブル１０が基準姿勢である場合、複数の第２反射材２８のうち制御ケーブル１０の折り返し部分よりも制御盤９の側に取り付けられた第２反射材２８は、当該画像における規定の範囲に写らない。 When the control cable 10 is in the normal state of the reference posture, the portion closer to the control panel 9 than the folded portion of the first surface 10a of the control cable 10 faces the camera 22 side. In this state, the first reflector 27 attached closer to the control panel 9 than the folded portion of the control cable 10 and positioned below the car 7 appears within a prescribed range in the image captured by the camera 22 . When the control cable 10 is in the reference posture, the second reflector 28 attached closer to the control panel 9 than the folded portion of the control cable 10 among the plurality of second reflectors 28 is within the prescribed range in the image. Not captured.
　制御ケーブル１０がねじれた状態などの基準姿勢とは異なる第１姿勢である場合、第１面１０ａのうち折り返し部分よりも制御盤９の側の部分は、カメラ２２とは反対側を向く。第２面１０ｂのうち折り返し部分よりも制御盤９の側の部分は、カメラ２２の側を向く。この場合、制御ケーブル１０の折り返し部分よりも制御盤９の側に取り付けられ、かつかご７よりも下方に位置する複数の第１反射材２７のうち１以上の第１反射材２７は、当該画像に写らない。また、制御ケーブル１０が第１姿勢である場合、制御ケーブル１０の折り返し部分よりも制御盤９の側に取り付けられた複数の第２反射材２８のうち１以上の第２反射材２８は、当該画像に写る。 When the control cable 10 is in a first posture different from the reference posture, such as when the control cable 10 is twisted, the portion of the first surface 10a closer to the control panel 9 than the folded portion faces the opposite side of the camera 22. A portion of the second surface 10b closer to the control panel 9 than the folded portion faces the camera 22 side. In this case, one or more of the plurality of first reflectors 27 attached to the control panel 9 side of the folded portion of the control cable 10 and positioned below the car 7 is the image does not appear in Further, when the control cable 10 is in the first posture, one or more of the plurality of second reflectors 28 attached to the control panel 9 side of the folded portion of the control cable 10 are appear in the image.
　カメラ２２は、無線電波によって撮影した画像の情報を送信する。携帯端末２４は、画像の情報を示す無線電波を受信する。携帯端末２４の画面には、受信した画像が表示される。保守員は、携帯端末２４に表示された画像を肉眼で確認することで制御ケーブル１０が基準姿勢であるか否かを判断する。例えば、当該画像において第１反射材２７が規定の範囲に写っている場合、保守員は、制御ケーブル１０が基準姿勢であると判断する。例えば、当該画像において折り返し部分よりも制御盤９の側に取り付けられた第２反射材２８が写っている場合、保守員は、制御ケーブル１０が基準姿勢とは別の姿勢であると判断する。この場合、保守員は、制御ケーブル１０の姿勢を点検する作業を行う。 The camera 22 transmits the information of the captured image by radio waves. The mobile terminal 24 receives radio waves indicating image information. The received image is displayed on the screen of the mobile terminal 24 . The maintenance staff checks the image displayed on the mobile terminal 24 with the naked eye to determine whether the control cable 10 is in the reference posture. For example, when the first reflector 27 appears in the specified range in the image, the maintenance person determines that the control cable 10 is in the reference posture. For example, if the image shows the second reflector 28 attached closer to the control panel 9 than the folded portion, the maintenance person determines that the control cable 10 is in a different posture from the reference posture. In this case, maintenance personnel perform work to check the posture of the control cable 10 .
　次に、図２と図３とを用いて、照明ユニット２１とカメラ２２とを説明する。
　図２は実施の形態１における姿勢確認システムが適用されるエレベーターのかごを下側からみた図である。図３は実施の形態１における姿勢確認システムの照明とカメラとを示す図である。 Next, the illumination unit 21 and the camera 22 will be described with reference to FIGS. 2 and 3. FIG.
FIG. 2 is a bottom view of an elevator car to which the attitude confirmation system according to the first embodiment is applied. FIG. 3 is a diagram showing lighting and a camera of the posture confirmation system according to Embodiment 1. FIG.
　図２に示されるように、照明ユニット２１は、かご７の下部において、かご７の下方を照らし得る向きに設けられる。カメラ２２は、かご７の下部において、制御ケーブル１０を含むかご７の下方を撮影し得る向きに設けられる。 As shown in FIG. 2, the lighting unit 21 is provided in the lower part of the car 7 in such a direction as to illuminate the lower part of the car 7 . The camera 22 is provided in the lower part of the car 7 and is oriented so as to photograph the lower part of the car 7 including the control cable 10 .
　図３に示されるように照明ユニット２１は、ソケット２９とアダプタ３０と電球３１とを備える。 The lighting unit 21 includes a socket 29, an adapter 30, and a light bulb 31, as shown in FIG.
　ソケット２９は、かご７の下部において梁に固定される。ソケット２９は、図３には図示されない遠隔監視装置２５と電気的に接続される。アダプタ３０は、ソケット２９に機械的かつ電気的に接続される。電球３１は、アダプタ３０に機械的かつ電気的に接続される。 The socket 29 is fixed to the beam at the bottom of the car 7. Socket 29 is electrically connected to remote monitoring device 25, not shown in FIG. Adapter 30 is mechanically and electrically connected to socket 29 . Bulb 31 is mechanically and electrically connected to adapter 30 .
　電源線２３の他端は、プラグ２３ａを有する。電源線２３は、プラグ２３ａを介してアダプタ３０に機械的かつ電気的に接続される。 The other end of the power line 23 has a plug 23a. The power line 23 is mechanically and electrically connected to the adapter 30 via a plug 23a.
　アダプタ３０は、ソケット２９に供給された電力を電球３１とカメラ２２とに分配する。 The adapter 30 distributes the power supplied to the socket 29 to the light bulb 31 and the camera 22.
　カメラ２２は、アンテナ３２を備える。アンテナ３２は、カメラ２２が撮影した画像の情報を示す電波を発信し得るよう設けられる。 The camera 22 includes an antenna 32. Antenna 32 is provided so as to be capable of transmitting radio waves indicating information of an image captured by camera 22 .
　次に、図４を用いて、カメラ２２が撮影する画像の例を説明する。
　図４は実施の形態１における姿勢確認部材と制御ケーブルとが写る画像を示す図である。 Next, an example of an image captured by the camera 22 will be described with reference to FIG.
FIG. 4 is a diagram showing an image showing a posture confirmation member and a control cable according to Embodiment 1. FIG.
　図４において、破線で囲われた範囲Ａは、図４には図示されないカメラ２２が撮影した画像に設定される規定の範囲である。例えば、規定の範囲として、制御ケーブル１０のうち折り返し部分よりも図４には図示されない制御盤９の側に位置する部分が存在する範囲が設定される。 In FIG. 4, range A enclosed by a dashed line is a prescribed range set for an image captured by camera 22 (not shown in FIG. 4). For example, as the specified range, a range is set in which a portion of the control cable 10 is positioned closer to the control panel 9 (not shown in FIG. 4) than the folded portion.
　また、一点鎖線で囲われた範囲Ｂには、第２反射材２８の像が存在する。範囲Ｂが破線で囲われた範囲Ａではないため、保守員は、当該制御ケーブル１０が基準姿勢とは別の姿勢であるとは判断しない。 Also, the image of the second reflector 28 exists in the range B surrounded by the dashed line. Since the range B is not the range A enclosed by the dashed line, the maintenance personnel does not judge that the control cable 10 is in a posture other than the reference posture.
　以上で説明した実施の形態１によれば、姿勢確認部材２６は、第１反射体２７ａと第１取付体２７ｂとを備える。第１反射体２７ａは、光を反射する。このため、第１反射体２７ａは、カメラ２２が撮影する画像において容易に視認され得る。また、第１取付体２７ｂは、制御ケーブル１０が基準姿勢である場合にカメラ２２に撮影され、制御ケーブル１０が基準姿勢とは異なる第１姿勢である場合にカメラ２２に撮影されない位置に第１反射体２７ａを取り付ける。このため、カメラ２２に撮影された画像において、制御ケーブル１０が基準姿勢とは別の姿勢となっていることを容易に確認できる。なお、基準姿勢は、第１面１０ａがカメラ２２を向く制御ケーブル１０の姿勢である。第１姿勢は、第２面１０ｂがカメラ２２を向く制御ケーブル１０の姿勢である。 According to Embodiment 1 described above, the posture confirmation member 26 includes the first reflector 27a and the first mounting body 27b. The first reflector 27a reflects light. Therefore, the first reflector 27a can be easily visually recognized in the image captured by the camera 22. As shown in FIG. Further, the first mounting body 27b is located at a position where the camera 22 is photographed when the control cable 10 is in the reference posture and is not photographed by the camera 22 when the control cable 10 is in the first posture different from the reference posture. Attach the reflector 27a. Therefore, in the image captured by the camera 22, it can be easily confirmed that the control cable 10 is in a posture different from the reference posture. The reference posture is the posture of the control cable 10 in which the first surface 10 a faces the camera 22 . The first orientation is the orientation of the control cable 10 with the second surface 10b facing the camera 22 .
　なお、第１反射体２７ａは、光を反射する角度によって反射光の色を変化させる性質を有していてもよい。カメラ２２が撮影した画像における第１反射体２７ａの像の色は、制御ケーブル１０の中間部の姿勢に応じて変化する。この場合、保守員は、制御ケーブル１０が基準姿勢である状態の第１反射体２７ａの像の色に基づいて制御ケーブル１０の姿勢を判断してもよい。このため、制御ケーブル１０の姿勢をより容易に確認できる。 Note that the first reflector 27a may have the property of changing the color of the reflected light depending on the angle at which the light is reflected. The color of the image of the first reflector 27 a in the image captured by the camera 22 changes according to the orientation of the intermediate portion of the control cable 10 . In this case, the maintenance personnel may judge the attitude of the control cable 10 based on the color of the image of the first reflector 27a when the control cable 10 is in the reference attitude. Therefore, the posture of the control cable 10 can be confirmed more easily.
　また、姿勢確認部材２６は、第２反射体２８ａと第２取付体２８ｂとを備える。第２反射体２８ａは、光を反射する。このため、制御ケーブル１０が基準姿勢とは別の姿勢である場合に、作業員は、カメラ２２が撮影した画像において第２反射体２８ａの像を容易に視認できる。また、第２取付体２８ｂは、第２反射体２８ａを制御ケーブル１０が基準姿勢である場合にカメラ２２に撮影されず、制御ケーブル１０が基準姿勢とは別の姿勢である場合にカメラ２２に撮影される。このため、制御ケーブル１０の姿勢を容易に確認できる。 Also, the posture confirmation member 26 includes a second reflector 28a and a second mounting body 28b. The second reflector 28a reflects light. Therefore, when the control cable 10 is in a posture different from the reference posture, the worker can easily visually recognize the image of the second reflector 28a in the image captured by the camera 22. FIG. In addition, the second mounting body 28b does not allow the second reflector 28a to be photographed by the camera 22 when the control cable 10 is in the reference posture, and is not photographed by the camera 22 when the control cable 10 is in a posture different from the reference posture. be filmed. Therefore, the posture of the control cable 10 can be easily confirmed.
　また、複数の第１取付体２７ｂは、制御ケーブル１０の第１面１０ａのうちかご７が最も低い位置に存在する状態からかご７が最も高い位置に存在する状態までの間、カメラ２２が撮影可能な位置に複数の第１反射体２７ａを取り付ける。このため、昇降路３の内部のほぼ全体にわたって制御ケーブル１０の姿勢を確認できる。 Further, the plurality of first mounting bodies 27b are arranged such that the camera 22 photographs the state from the lowest position of the car 7 to the highest position of the car 7 on the first surface 10a of the control cable 10. A plurality of first reflectors 27a are attached at possible positions. Therefore, the attitude of the control cable 10 can be confirmed over almost the entire interior of the hoistway 3 .
　なお、実施の形態１の姿勢確認システム２０によれば、カメラ２２は、エレベーターシステム１が通常運転をしている時に制御ケーブル１０を撮影する。この際、制御ケーブル１０は、通常の自動運転と同じ速度で移動する。このため、姿勢確認システム２０は、通常の自動運転における制御ケーブル１０の動きの動特性を確認できる。また、制御ケーブル１０の動特性は、昇降路３の下部にいる保守員が目視で確認をすることがある。この場合、かご７は、自動運転よりも遅い手動運転で移動する。制御ケーブル１０の動特性は、かご７が手動運転で上方へ移動する条件でのみ確認される。実施の形態１の姿勢確認システム２０によれば、かご７が自動運転の速度で昇降する条件における制御ケーブル１３の動特性を確認することができる。 According to the posture confirmation system 20 of Embodiment 1, the camera 22 photographs the control cable 10 while the elevator system 1 is operating normally. At this time, the control cable 10 moves at the same speed as normal automatic operation. Therefore, the attitude confirmation system 20 can confirm the dynamic characteristics of the movement of the control cable 10 during normal automatic operation. In addition, the dynamic characteristics of the control cable 10 may be visually checked by a maintenance worker at the bottom of the hoistway 3 . In this case, the car 7 moves by manual operation slower than automatic operation. The dynamics of the control cable 10 are verified only under the condition that the car 7 is moved upwards in manual operation. According to the attitude confirmation system 20 of Embodiment 1, it is possible to confirm the dynamic characteristics of the control cable 13 under the condition that the car 7 ascends and descends at the speed of automatic operation.
　なお、カメラ２２は、連続した画像である動画の情報を携帯端末２４に送信してもよい。 Note that the camera 22 may transmit moving image information, which is a series of images, to the mobile terminal 24 .
　なお、カメラ２２は、制御ケーブル１０に限らない昇降路３の内部の機器を撮影する用途で設置されたカメラであってもよい。このため、姿勢確認システム２０を安価に構成することができる。 Note that the camera 22 may be a camera installed for the purpose of photographing equipment inside the hoistway 3 that is not limited to the control cable 10 . Therefore, the attitude confirmation system 20 can be configured at low cost.
　なお、第２反射体２８ａは、形状によって第１反射体２７ａと区別し得るよう設けられてもよい。 The second reflector 28a may be provided so as to be distinguishable from the first reflector 27a by its shape.
　なお、第１取付体２７ｂおよび第２取付体２８ｂは、接着剤ではなく、ベルト、金具、等の第１反射体２７ａまたは第２反射体２８ａを制御ケーブル１０に取り付けることができる部品であってもよい。 The first attachment body 27b and the second attachment body 28b are not adhesives, but parts such as belts, metal fittings, etc. that can attach the first reflector 27a or the second reflector 28a to the control cable 10. good too.
実施の形態２．
　図５は実施の形態２における姿勢確認システムの概要を示す図である。なお、実施の形態１の部分と同一又は相当部分には同一符号が付される。当該部分の説明は省略される。 Embodiment 2.
FIG. 5 is a diagram showing an outline of a posture confirmation system according to Embodiment 2. FIG. The same reference numerals are given to the same or corresponding parts as those of the first embodiment. Description of this part is omitted.
　図５に示されるように、実施の形態２において、姿勢確認システム２０は、解析装置４０を更に備える。 As shown in FIG. 5, the posture confirmation system 20 further includes an analysis device 40 in the second embodiment.
　解析装置４０は、建築物２とは別の建築物に設けられる。例えば、解析装置４０は、エレベーターシステム１を保守管理する会社の情報センターに設けられる。解析装置４０は、監視回線を通じて遠隔監視装置２５と通信し得るよう設けられる。 The analysis device 40 is installed in a building different from the building 2. For example, the analysis device 40 is provided in an information center of a company that maintains and manages the elevator system 1 . Analysis device 40 is provided to communicate with remote monitoring device 25 over a monitoring line.
　解析装置４０は、カメラ２２が制御ケーブル１０と複数の姿勢確認部材２６とを撮影した比較画像に基づいて、制御ケーブル１０が基準姿勢であるか否かを判定する。具体的には、解析装置４０は、基準姿勢の状態の制御ケーブル１０と複数の姿勢確認部材２６とが写る基準画像と比較画像との差異を検出することで、制御ケーブル１０が基準姿勢であるか否かを判定する。例えば、解析装置４０は、第２反射材２８の像の位置が基準画像と比較画像とで異なることを検出した場合、制御ケーブル１０が基準姿勢でないと判定する。 The analysis device 40 determines whether or not the control cable 10 is in the reference posture based on comparative images captured by the camera 22 of the control cable 10 and the plurality of posture confirmation members 26 . Specifically, the analysis device 40 detects the difference between the reference image showing the control cable 10 in the reference posture and the plurality of posture confirmation members 26 and the comparison image, thereby confirming that the control cable 10 is in the reference posture. Determine whether or not For example, when detecting that the position of the image of the second reflector 28 differs between the reference image and the comparison image, the analysis device 40 determines that the control cable 10 is not in the reference posture.
　実施の形態２において、遠隔監視装置２５は、カメラ２２から画像の情報を受信し得るよう設けられる。 In Embodiment 2, remote monitoring device 25 is provided to receive image information from camera 22 .
　遠隔監視装置２５は、規定の周期でカメラ２２に制御ケーブル１０の画像を撮影させる。例えば、エレベーターシステム１が通常運転している状態で、遠隔監視装置２５は、照明ユニット２１とカメラ２２とに電力を供給する。かご７が昇降路３の下部から上部へ移動する間に、カメラ２２は、制御ケーブル１０を撮影する。カメラ２２は、撮影した複数の画像の情報を遠隔監視装置２５に送信する。 The remote monitoring device 25 causes the camera 22 to capture images of the control cable 10 at regular intervals. For example, when the elevator system 1 is in normal operation, the remote monitoring device 25 powers the lighting unit 21 and the camera 22 . The camera 22 photographs the control cable 10 while the car 7 moves from the bottom to the top of the hoistway 3 . The camera 22 transmits information of the multiple captured images to the remote monitoring device 25 .
　遠隔監視装置２５は、カメラ２２から受信した画像の情報を記憶する。遠隔監視装置２５は、カメラ２２から受信した画像の情報を解析装置４０へ定期的に送信する。解析装置４０は、受信した画像の情報に基づいて制御ケーブル１０が基準姿勢であるか否かを判定する。例えば、制御ケーブル１０が基準姿勢でないと判定された場合、保守管理する会社の作業員は、保守員を建築物２に派遣する。 The remote monitoring device 25 stores image information received from the camera 22 . The remote monitoring device 25 periodically transmits image information received from the camera 22 to the analysis device 40 . The analysis device 40 determines whether or not the control cable 10 is in the reference posture based on the received image information. For example, when it is determined that the control cable 10 is not in the reference posture, a worker of a maintenance company dispatches a maintenance worker to the building 2 .
　以上で説明した実施の形態２によれば、姿勢確認システム２０は、カメラ２２と第１反射体２７ａと第１取付体２７ｂと解析装置４０とを備える。解析装置４０は、カメラ２２が撮影した画像の情報に基づいて制御ケーブル１０が基準姿勢とは別の姿勢であるか否かを判定する。第１反射体２７ａと第１取付体２７ｂとが制御ケーブル１０に設けられるため、解析装置４０は、制御ケーブル１０の姿勢を容易に確認できる。その結果、制御ケーブル１０の姿勢を監視することができる。 According to Embodiment 2 described above, posture confirmation system 20 includes camera 22 , first reflector 27 a , first mounting body 27 b , and analysis device 40 . The analysis device 40 determines whether or not the control cable 10 is in a posture different from the reference posture based on the information of the image captured by the camera 22 . Since the control cable 10 is provided with the first reflector 27 a and the first mounting body 27 b , the analysis device 40 can easily check the posture of the control cable 10 . As a result, the attitude of the control cable 10 can be monitored.
　なお、解析装置４０は、比較画像における規定の範囲に第２反射材２８の像が存在することを検出した場合、制御ケーブル１０が基準姿勢でないと判定してもよい。 Note that the analysis device 40 may determine that the control cable 10 is not in the reference posture when detecting that the image of the second reflector 28 exists in the specified range in the comparison image.
　なお、解析装置４０は、制御ケーブル１０が基準姿勢とは異なる第１姿勢であるか否かを判定してもよい。 Note that the analysis device 40 may determine whether or not the control cable 10 is in the first orientation different from the reference orientation.
　なお、遠隔監視装置２５は、カメラ２２が撮影した複数の画像を繋ぎ合わせ、昇降路３の下部から上部が写るパノラマ画像の情報を記憶してもよい。この場合、解析装置４０は、当該パノラマ画像の情報に基づいて、制御ケーブル１０が基準姿勢でないと判定してもよい。 It should be noted that the remote monitoring device 25 may combine a plurality of images captured by the camera 22 and store information on a panoramic image showing the upper and lower parts of the hoistway 3 . In this case, the analysis device 40 may determine that the control cable 10 is not in the reference posture based on the information of the panoramic image.
　次に、図６を用いて、解析装置４０を構成するハードウェアの例を説明する。
　図６は実施の形態２における姿勢確認システムの解析装置のハードウェア構成図である。 Next, an example of hardware constituting the analysis device 40 will be described with reference to FIG.

For example, the function of receiving information from the remote monitoring device 25 is implemented by a processing circuit as dedicated hardware 200, and the functions other than the function of receiving information from the remote monitoring device 25 are implemented by at least one processor 100a. It may be realized by reading and executing a program stored in one memory 100b.
