　かご４ｂが目的階に近付いた際、運転制御装置６は、第１ブレーキチョッパ５ｄと第２ブレーキチョッパ５ｇとへの給電を遮断する。当該遮断により、第１ブレーキコイル５ｃと第２ブレーキコイル５ｆとへの給電が遮断される。当該遮断により、第１ブレーキライニング５ｅと第２ブレーキライニング５ｈが綱車２ｄを制動する。当該制動により、主索４ａが制動される。当該制動により、かご４ｂが制動される。その後、第１ブレーキライニング５ｅと第２ブレーキライニング５ｈは綱車２ｄを静止保持する。当該静止保持により、主索４ａが静止保持される。当該静止保持により、かご４ｂが静止保持される。 When the car 4b approaches the destination floor, the operation control device 6 cuts off the power supply to the first brake chopper 5d and the second brake chopper 5g. By the interruption, power supply to the first brake coil 5c and the second brake coil 5f is interrupted. By the interruption, the first brake lining 5e and the second brake lining 5h brake the sheave 2d. The main rope 4a is braked by the braking. The car 4b is braked by the braking. Thereafter, the first brake lining 5e and the second brake lining 5h hold the sheave 2d stationary. The main rope 4a is held stationary by the stationary holding. By the stationary holding, the car 4b is held stationary.
　この際、かご移動検出器２ｆは、電動機２ｃの回転角度に基づいてかご４ｂの移動量を検出する。かご移動検出器２ｆは、かご４ｂの移動量に応じて状態信号９を出力する。運転制御装置６は、かご速度検出器として、状態信号９に基づいてかご４ｂの速度を検出する。運転制御装置６は、かご４ｂの速度に基づいてかご４ｂが目的階で静止保持されているか否かを判定する。 At this time, the car movement detector 2f detects the movement amount of the car 4b based on the rotation angle of the electric motor 2c. The car movement detector 2f outputs a status signal 9 according to the movement amount of the car 4b. The operation control device 6 detects the speed of the car 4b based on the state signal 9 as a car speed detector. The operation control device 6 determines whether or not the car 4b is held stationary on the destination floor based on the speed of the car 4b.
　かご４ｂが目的階で静止保持されている場合、運転制御装置６は、ゲート４ｃを開く。この際、ゲートスイッチ４ｄは、ゲート４ｃが開放されていることを検出する。ゲートスイッチ４ｄは、当該検出に応じた状態信号１０を出力する。ドア３ａは、ゲート４ｃに追従して開く。この際、ドアスイッチ３ｂは、ドア３ａが開放されていることを検出する。ドアスイッチ３ｂは、当該検出に応じた状態信号１１を出力する。 When the car 4b is held stationary on the destination floor, the operation control device 6 opens the gate 4c. At this time, the gate switch 4d detects that the gate 4c is open. The gate switch 4d outputs a status signal 10 corresponding to the detection. The door 3a opens following the gate 4c. At this time, the door switch 3b detects that the door 3a is opened. The door switch 3b outputs a status signal 11 corresponding to the detection.
　戸開走行検出器７ｄは、状態信号９～１１に基づいてかご４ｂが戸開走行を行っているか否かを判定する。具体的には、戸開走行検出器７ｄは、ドア３ａ及びゲート４ｃの少なくとも一方が開放された状態でかご４ｂが乗場の床面に対して予め設定された距離以上離れた位置まで移動するか否かを予測する。 The door-open travel detector 7d determines whether the car 4b is performing the door-open travel based on the state signals 9-11. Specifically, whether the door-open travel detector 7d moves to a position where the car 4b is separated from the floor of the landing by a predetermined distance or more with at least one of the door 3a and the gate 4c opened. Predict whether or not.
　かご４ｂが戸開走行を行っている場合、戸開走行検出器７ｄは、トランジスタ素子７ｃへの印加電圧１２を遮断する。当該遮断により、トランジスタ素子７ｃは、オフの状態となる。その結果、コイル７ｂへの給電が遮断される。 When the car 4b is running open, the door open detector 7d blocks the voltage 12 applied to the transistor element 7c. By the interruption, the transistor element 7c is turned off. As a result, power supply to the coil 7b is interrupted.
　この際、主接点２ａが開く。その結果、電力変換装置２ｂへの給電が遮断される。当該遮断により、電動機２ｃへの給電が遮断される。当該遮断により、電動機２ｃが停止する。 At this time, the main contact 2a is opened. As a result, power supply to the power converter 2b is interrupted. By the interruption, the power supply to the electric motor 2c is interrupted. The electric motor 2c stops by the interruption.
　この際、主接点５ｂが開く。その結果、第１ブレーキコイル５ｃと第２ブレーキコイル５ｆとへの給電が遮断される。当該遮断により、第１ブレーキライニング５ｅと第２ブレーキライニング５ｈが綱車２ｄを制動する。当該制動により、主索４ａが制動される。当該制動により、かご４ｂが制動される。その後、第１ブレーキライニング５ｅと第２ブレーキライニング５ｈが綱車２ｄを静止保持する。当該静止保持におり、主索４ａが静止保持される。当該静止保持により、かご４ｂが静止保持される。その結果、かご４ｂは乗場の床面に対して予め設定された距離以内の位置で停止する。 At this time, the main contact 5b is opened. As a result, power supply to the first brake coil 5c and the second brake coil 5f is interrupted. By the interruption, the first brake lining 5e and the second brake lining 5h brake the sheave 2d. The main rope 4a is braked by the braking. The car 4b is braked by the braking. Thereafter, the first brake lining 5e and the second brake lining 5h hold the sheave 2d stationary. In the stationary holding, the main rope 4a is held stationary. By the stationary holding, the car 4b is held stationary. As a result, the car 4b stops at a position within a preset distance with respect to the floor of the hall.

　図２に示すように、かご４ｂが下方向に戸開走行した場合、かご４ｂは、乗場の床面に対して予め設定された距離Ｌ１内の範囲の位置で停止する。距離Ｌ１は、かご４ｂの出入口上端と乗場の床面との間の開口部の鉛直方向の距離に応じて設定される。当該距離は、かご４ｂ内の利用者が乗場に脱出し得るように設定される。 As shown in FIG. 2, when the car 4b travels downward, the car 4b stops at a position in a range within a preset distance L1 with respect to the floor of the landing. The distance L1 is set according to the distance in the vertical direction of the opening between the upper end of the entrance / exit of the car 4b and the floor of the hall. The distance is set so that a user in the car 4b can escape to the landing.

The distance L2 is set according to the vertical distance between the lower end of the apron 4f of the car 4b and the floor of the landing. The distance is set so that the user of the hall does not fall.
　次に、図４を用いて、かご４ｂの戸開走行を検出する際のかご４ｂの速度を説明する。
　図４はこの発明の実施の形態１におけるエレベータシステムがかごの戸開走行を検出する際のかごの速度を説明するための図である。 Next, with reference to FIG. 4, the speed of the car 4b when detecting the opening of the car 4b will be described.
FIG. 4 is a diagram for explaining the speed of the car when the elevator system according to the first embodiment of the present invention detects the opening of the car.
　図４の横軸はかご４ｂが直近に停止していた階の乗場の床面に対するかご４ｂの相対位置ｘである。図４の縦軸はかご４ｂの速度ｖである。Δｘはかご４ｂの相対位置の検出誤差である。Δｖはかご４ｂの速度の検出誤差である。 The horizontal axis of FIG. 4 is the relative position x of the car 4b with respect to the floor surface of the landing on the floor where the car 4b has stopped most recently. The vertical axis in FIG. 4 is the speed v of the car 4b. Δx is a detection error of the relative position of the car 4b. Δv is a speed detection error of the car 4b.
　例えば、戸開走行検出器７ｄは、学習運転の際に各乗場におけるかご移動検出器２ｆの状態信号９を記憶する。戸開走行検出器７ｄは、かご位置検出器として、状態信号９に基づいてかご４ｂの相対位置ｘを算出する。この際、戸開走行検出器７ｄは、かご４ｂの速度ｖが速度監視レベルＶ＿ｕｃｍ（ｘ）を超過した場合にかご４ｂの戸開走行を検出する。例えば、速度監視レベルＶ＿ｕｃｍ（ｘ）は、ブレーキ装置５の制動力による減速度ｄを用いて次の（１）式で算出される。 For example, the door-open running detector 7d stores the state signal 9 of the car movement detector 2f at each landing during the learning operation. As a car position detector, the door-open running detector 7d calculates the relative position x of the car 4b based on the state signal 9. At this time, the door-open travel detector 7d detects the door-open travel of the car 4b when the speed v of the car 4b exceeds the speed monitoring level V_ucm (x). For example, the speed monitoring level V_ucm (x) is calculated by the following equation (1) using the deceleration d due to the braking force of the brake device 5.
ｉｆ　Ｌ１＋Δｘ＜ｘ＜Ｌ２－Δｘ
Ｖ＿ｕｃｍ（ｘ）＝ｍｉｎ｛Ｖ＿ｕｃｍ＿ｄｎ（ｘ）、Ｖ＿ｕｃｍ＿ｕｐ（ｘ）｝
Ｖ＿ｕｃｍ＿ｄｎ（ｘ）＝ｍａｘ｛０、√（２×ｄ×（ｘ－（Ｌ１＋Δｘ）））－Δｖ｝
Ｖ＿ｕｃｍ＿ｕｐ（ｘ）＝ｍａｘ｛０、√（２×ｄ×（（Ｌ２－Δｘ）－ｘ））－Δｖ｝
ｅｌｓｅ
Ｖ＿ｕｃｍ（ｘ）＝０　　　（１） if L1 + Δx <x <L2-Δx
V_ucm (x) = min {V_ucm_dn (x), V_ucm_up (x)}
V_ucm_dn (x) = max {0, √ (2 × d × (x− (L1 + Δx))) − Δv}
V_ucm_up (x) = max {0, √ (2 × d × ((L2−Δx) −x)) − Δv}
else
V_ucm (x) = 0 (1)
　以上で説明した実施の形態１によれば、かご４ｂの許容移動範囲は、かご４ｂが上方向に戸開走行を開始した場合とかご４ｂが下方向に戸開走行を開始した場合とで異なる範囲に設定される。例えば、かご４ｂが上方向の戸開走行を開始した場合は、かご４ｂのエプロン４ｆの長さに合わせて、かご４ｂの許容移動範囲が確保される。かご４ｂが下方向の戸開走行を開始した場合は、かご４ｂの出入口の高さに合わせて、かご４ｂの許容移動範囲が確保される。その結果、かご４ｂの戸開走行時における安全性を確保しつつ、かご４ｂの戸開走行の誤検出を抑制することができる。 According to the first embodiment described above, the allowable movement range of the car 4b is different between the case where the car 4b starts door-opening in the upward direction and the case where the car 4b starts door-opening in the downward direction. Set to range. For example, when the car 4b starts the upward door opening travel, the allowable movement range of the car 4b is secured in accordance with the length of the apron 4f of the car 4b. When the car 4b starts to open the door in the downward direction, the allowable movement range of the car 4b is secured according to the height of the entrance / exit of the car 4b. As a result, it is possible to suppress erroneous detection of the car 4b when the car 4b is opened while the safety of the car 4b when the car 4b is opened.
　また、速度監視レベルは、かご４ｂの減速度に基づいて設定される。このため、かご４ｂの戸開走行をより正確に検出することができる。 Also, the speed monitoring level is set based on the deceleration of the car 4b. For this reason, it is possible to detect the opening of the car 4b more accurately.
　なお、かご４ｂの戸開走行が検出された際に、ロープブレーキ、非常止め等、ブレーキ装置５以外の制動装置を用いてかご４ｂを制動してもよい。 When the car 4b is detected to open, the car 4b may be braked using a braking device other than the brake device 5, such as a rope brake or an emergency stop.
　以上のように、この発明に係るエレベータシステムは、かごの戸開走行の誤検出を抑制するエレベータに利用できる。 As described above, the elevator system according to the present invention can be used for an elevator that suppresses erroneous detection of car door-open running.
