An operation controller which, during the diagnostic mode when the car is stopped, determines the switching operation of the power supply switching means according to the switching drive command from the open-door running protection unit, and then generates a switching drive signal corresponding to that determination.

Description

エレベータ装置Elevator equipment
　この発明は、かごの戸開走行を抑制する機能を有するエレベータ装置に関する。 This invention relates to an elevator apparatus having a function of suppressing the car from opening the door.
　本明細書において、「戸開走行」とは、戸開停止中のかごが戸閉せずに走行を開始した状態と、かごの走行中にかご及び乗場の少なくともいずれか一方が戸開した状態とを含むものとする。 In this specification, “door-open travel” means a state in which a car that has not been opened is not closed, and a state in which at least one of the car and the landing is open while the car is traveling. And
　近年、一般的なエレベータ装置には、かごの戸開走行をより確実に抑制するために、戸開走行保護装置（戸開走行保護部）が用いられている。このような戸開走行保護装置は、戸開停止中のかごが戸閉せずに走行を開始したことを検出した場合、又はかごの走行中にかご及び乗場の少なくともいずれか一方が戸開したことを検出した場合に、かごの走行を急停止させるための保護機能を有する。 In recent years, a door-opening travel protection device (door-opening travel protection unit) has been used in general elevator devices in order to more reliably suppress the car door-opening travel. When such a door-opening travel protection device detects that a car that has stopped opening has started running without closing the door, or at least one of the car and the landing area has been opened. When this is detected, it has a protective function for suddenly stopping the car.
　具体的に、このような戸開走行保護装置の保護機能を実現するためには、例えば、次の第１の遮断構成、又は第２の遮断構成をエレベータ装置の給電系に設ける必要がある。第１の遮断構成では、主回路及びブレーキコイル少なくともいずれか一方の電源ラインに電磁接触器（給電切換手段、コンタクタ）が設けられ、その電磁接触器の開極・閉極が戸開走行保護装置によって直接的に制御される。そして、電磁接触器の開極・閉極が切り換えられることにより、駆動機又はブレーキコイルへの給電・遮断が切り換えられる。 Specifically, in order to realize the protection function of such a door-opening travel protection device, for example, it is necessary to provide the following first cutoff configuration or second cutoff configuration in the power supply system of the elevator apparatus. In the first breaking configuration, an electromagnetic contactor (power supply switching means, contactor) is provided on at least one of the power line of the main circuit and the brake coil, and the opening / closing of the electromagnetic contactor is a door-open travel protection device. Directly controlled by Then, by switching between opening and closing of the magnetic contactor, power supply and interruption to the driving machine or the brake coil are switched.
　また、第２の遮断構成では、主回路及びブレーキコイル少なくともいずれか一方の電源ラインに電磁接触器が設けられ、その電磁接触器の開極・閉極がエレベータ運転制御装置によって直接的に制御される。この第２の遮断構成において、エレベータ運転制御装置と電磁接触器とを結ぶ制御ラインに半導体素子等が設けられ、戸開走行保護装置からの戸開走行保護信号がその半導体素子に加えられ、電磁接触器が開極状態となる。 In the second breaking configuration, an electromagnetic contactor is provided in at least one of the power line of the main circuit and the brake coil, and the opening / closing of the electromagnetic contactor is directly controlled by the elevator operation control device. The In this second shut-off configuration, a semiconductor element or the like is provided in a control line connecting the elevator operation control device and the electromagnetic contactor, and a door opening travel protection signal from the door opening travel protection device is applied to the semiconductor element, The contactor is opened.
　なお、この発明のエレベータ装置に関連する文献公知技術としては、例えば特許文献１に示すようなエレベータ戸開発車防止装置がある。このエレベータ戸開発車防止装置では、落下防止手段が、戸開発車を検出した際に、ロープグリッパを作動させて、かごの走行を急停止させる。 In addition, as literature known technology related to the elevator apparatus of the present invention, there is an elevator door development vehicle prevention apparatus as shown in Patent Document 1, for example. In this elevator door development vehicle prevention device, when the fall prevention means detects the door development vehicle, the rope gripper is operated to suddenly stop the traveling of the car.

　ここで、エレベータ装置が正常に動作している状態においても、戸開走行保護装置が自身の保護機能について正常に動作することを定期的に診断する必要がある。また、機能安全の観点から、戸開走行保護装置は、エレベータ運転制御装置から独立していることが望ましい。 Here, even when the elevator apparatus is operating normally, it is necessary to periodically diagnose that the door-opening travel protection apparatus operates normally with respect to its own protection function. Further, from the viewpoint of functional safety, it is desirable that the door-opening travel protection device is independent of the elevator operation control device.
　さらに、既存のエレベータ装置に戸開走行保護装置を追加する際に、第１の遮断構成を採用した場合には、主回路及びブレーキ回路にそれぞれ電磁接触器を挿入し、さらに各電磁接触器に対して駆動信号線を新たに追加する必要がある。このため、部品点数削減や、省配線化や、省スペース化の観点から、第２の遮断構成を採用した方が有利である。 Furthermore, when the door opening travel protection device is added to the existing elevator device, when the first shut-off configuration is adopted, an electromagnetic contactor is inserted into each of the main circuit and the brake circuit, and each electromagnetic contactor is further inserted. On the other hand, it is necessary to newly add a drive signal line. For this reason, it is more advantageous to adopt the second blocking configuration from the viewpoint of reducing the number of parts, wiring saving, and space saving.
　しかしながら、第２の遮断構成を採用した場合において、既存の電磁接触器の開極・閉極がエレベータ運転制御装置によって制御され、また、エレベータ運転制御装置及び戸開走行保護装置が互いに独立している。このため、エレベータ運転制御装置の制御状態によっては、戸開走行保護装置の戸開走行保護信号のみでは、電磁接触器が開極状態とならない場合があり、戸開走行保護装置が自身の保護機能に関する自己診断処理を実行することが困難であった。 However, when the second breaking configuration is adopted, the opening / closing of the existing magnetic contactor is controlled by the elevator operation control device, and the elevator operation control device and the door opening travel protection device are independent of each other. Yes. For this reason, depending on the control state of the elevator operation control device, the electromagnetic contactor may not be in the open state only with the door open travel protection signal of the door open travel protection device, and the door open travel protection device has its own protective function. It was difficult to execute the self-diagnosis process.
　この発明は、上記のような課題を解決するためになされたものであり、運転制御部及び戸開走行保護部が共同して給電切換手段の切換動作を制御することができるエレベータ装置を得ることを目的とする。 This invention is made in order to solve the above subjects, and obtains the elevator apparatus which can control the switching operation | movement of an electric power supply switching means in cooperation with an operation control part and a door open travel protection part.

1 and 2, the elevator device includes a drive device 10, a brake device 20, a hoistway device 30, a landing device 40, a door-opening travel protection device 50 as a door-opening travel protection unit, and an elevator operation control as an operation control unit. A device 60 and a shut-off control logic circuit 70 are included.
　駆動装置１０は、商用電源１に接続された主回路用電磁遮断器（給電切換手段）１１と、主回路用電磁遮断器１１に接続された電力変換機１２と、電力変換機１２から電力を受けるモータ１３と、モータ１３の駆動によって回転されるシーブ１４とを有している。モータ１３の駆動は、エレベータ運転制御装置６０によって制御される。 The drive device 10 includes a main circuit electromagnetic circuit breaker (power supply switching means) 11 connected to the commercial power source 1, a power converter 12 connected to the main circuit electromagnetic circuit breaker 11, and power from the power converter 12. It has a receiving motor 13 and a sheave 14 rotated by driving of the motor 13. The drive of the motor 13 is controlled by the elevator operation control device 60.
　主回路用電磁遮断器１１は、モータ１３の電源ライン、即ち主回路に設けられている。また、主回路用電磁遮断器１１は、＃ＭＣ主接点１１ａ、＃ＭＣ補助接点１１ｂ及び＃ＭＣコイル１１ｃを有している。＃ＭＣコイル１１ｃが通電状態（励磁状態）のときには、＃ＭＣ主接点１１ａが閉極状態であり、＃ＭＣ補助接点１１ｂが開極状態である。 The main circuit electromagnetic circuit breaker 11 is provided in the power line of the motor 13, that is, the main circuit. The main circuit electromagnetic circuit breaker 11 includes a #MC main contact 11a, a #MC auxiliary contact 11b, and a #MC coil 11c. When the #MC coil 11c is in an energized state (excited state), the #MC main contact 11a is in a closed state and the #MC auxiliary contact 11b is in an open state.
　これに対して、＃ＭＣコイル１１ｃが通電遮断状態（非励磁状態）のときには、＃ＭＣ主接点１１ａが開極状態であり、＃ＭＣ補助接点１１ｂが閉極状態である。即ち、主回路用電磁遮断器１１の＃ＭＣ主接点１１ａの閉極・開極によって、モータ１３への給電・遮断が切り換えられる。なお、＃ＭＣ補助接点１１ｂは、戸開走行保護装置５０及びエレベータ運転制御装置６０に電気的に接続されている。 On the other hand, when the #MC coil 11c is in the energization cut-off state (non-excited state), the #MC main contact 11a is in the open state and the #MC auxiliary contact 11b is in the closed state. In other words, the power supply to the motor 13 is switched between being opened and closed by closing and opening the #MC main contact 11 a of the main circuit electromagnetic circuit breaker 11. The #MC auxiliary contact 11b is electrically connected to the door-opening travel protection device 50 and the elevator operation control device 60.
　モータ１３及びシーブ１４は、昇降路の上部に配置されている。ブレーキ装置２０は、モータ１３の駆動によってシーブ１４とともに回転するブレーキホイール（図示せず）と、第１ブレーキライニング２１と、第２ブレーキライニング２２と、第１ブレーキコイル２３と、第２ブレーキコイル２４と、第１ばね（図示せず）と、第２ばね（図示せず）と、第１ブレーキチョッパ２５と、第２ブレーキチョッパ２６と、ブレーキ用電磁遮断器（給電切換手段）２７とを有している。 The motor 13 and the sheave 14 are arranged in the upper part of the hoistway. The brake device 20 includes a brake wheel (not shown) that rotates together with the sheave 14 by driving the motor 13, a first brake lining 21, a second brake lining 22, a first brake coil 23, and a second brake coil 24. A first spring (not shown), a second spring (not shown), a first brake chopper 25, a second brake chopper 26, and a brake electromagnetic circuit breaker (power supply switching means) 27. is doing.
　第１ブレーキライニング２１及び第２ブレーキライニング２２は、それぞれ制動位置と開放位置との間で変位可能になっている。制動位置とは、第１ブレーキライニング２１及び第２ブレーキライニング２２がブレーキホイールの制動面（例えば外周面）と接触する位置である。開放位置とは、第１ブレーキライニング２１及び第２ブレーキライニング２２がブレーキホイールの制動面から間隔をおいて離れる位置である。つまり、開放位置とは、第１ブレーキライニング２１及び第２ブレーキライニング２２がブレーキホイールの制動面と非接触状態になる位置である。 The first brake lining 21 and the second brake lining 22 can be displaced between the braking position and the release position, respectively. The braking position is a position where the first brake lining 21 and the second brake lining 22 are in contact with the braking surface (for example, the outer peripheral surface) of the brake wheel. The open position is a position where the first brake lining 21 and the second brake lining 22 are spaced apart from the braking surface of the brake wheel. That is, the release position is a position where the first brake lining 21 and the second brake lining 22 are in a non-contact state with the braking surface of the brake wheel.
　第１ブレーキライニング２１及び第２ブレーキライニング２２は、それぞれ第１ばね及び第２ばねによって、ブレーキホイールの制動面へ向けて付勢されている。従って、第１ばね及び第２ばねによって、第１ブレーキライニング２１及び第２ブレーキライニング２２が回転中のブレーキホイールの制動面に押し付けられることにより、第１ブレーキライニング２１及び第２ブレーキライニング２２とブレーキホイールの制動面との間で摩擦力が生じる。この摩擦力によって、ブレーキホイールの回転、即ちモータ１３の回転が制動される。 The first brake lining 21 and the second brake lining 22 are urged toward the braking surface of the brake wheel by the first spring and the second spring, respectively. Accordingly, the first and second brake linings 21 and 22 are pressed against the braking surface of the rotating brake wheel by the first and second springs. A frictional force is generated between the braking surface of the wheel. This frictional force brakes the rotation of the brake wheel, that is, the rotation of the motor 13.
　また、第１ブレーキライニング２１及び第２ブレーキライニング２２は、それぞれ第１ブレーキコイル２３及び第２ブレーキコイル２４の電磁力によって、第１ばね及び第２ばねの付勢力に抗して、開放位置へ変位される。第１ブレーキコイル２３及び第２ブレーキコイル２４の励磁・消磁は、それぞれ第１ブレーキチョッパ２５及び第２ブレーキチョッパ２６を介して、エレベータ運転制御装置６０によって制御される。 The first brake lining 21 and the second brake lining 22 are moved to the open position against the biasing force of the first spring and the second spring by the electromagnetic force of the first brake coil 23 and the second brake coil 24, respectively. Displaced. Excitation / demagnetization of the first brake coil 23 and the second brake coil 24 is controlled by the elevator operation control device 60 via the first brake chopper 25 and the second brake chopper 26, respectively.
　ブレーキ用電磁遮断器２７は、第１ブレーキコイル２３と第１ブレーキチョッパ２５との間、及び第２ブレーキコイル２４と第２ブレーキチョッパ２６との間にそれぞれ介在されている。また、ブレーキ用電磁遮断器２７は、＃ＢＫ主接点２７ａ、＃ＢＫ補助接点２７ｂ及び＃ＢＫコイル２７ｃを有している。 The brake electromagnetic circuit breaker 27 is interposed between the first brake coil 23 and the first brake chopper 25 and between the second brake coil 24 and the second brake chopper 26, respectively. The brake electromagnetic circuit breaker 27 has a #BK main contact 27a, a #BK auxiliary contact 27b, and a #BK coil 27c.
　＃ＢＫコイル２７ｃが通電状態（励磁状態）のときには、＃ＢＫ主接点２７ａが閉極状態であり、＃ＢＫ２７補助接点２７ｂが開極状態である。これに対して、＃ＢＫコイル２７ｃが通電遮断状態（非励磁状態）のときには、＃ＢＫ主接点２７ａが開極状態であり、＃ＢＫ補助接点２７ｂが閉極状態である。即ち、ブレーキ用電磁遮断器２７の＃ＢＫ主接点２７ａの閉極・開極によって、第１ブレーキコイル２３及び第２ブレーキコイル２４への給電・遮断が切り換えられる。 When the #BK coil 27c is in an energized state (excited state), the #BK main contact 27a is in a closed state and the # BK27 auxiliary contact 27b is in an open state. On the other hand, when the #BK coil 27c is in the energization cut-off state (de-energized state), the #BK main contact 27a is in the open state and the #BK auxiliary contact 27b is in the closed state. In other words, the power supply / interruption to the first brake coil 23 and the second brake coil 24 is switched by closing / opening the #BK main contact 27a of the brake electromagnetic circuit breaker 27.
　また、＃ＢＫ補助接点２７ｂは、戸開走行保護装置５０及びエレベータ運転制御装置６０に電気的に接続されており、＃ＢＫ補助接点２７ｂの開極・閉極状態を示す信号２７ｂＡが戸開走行保護装置５０及びエレベータ運転制御装置６０に送られる。 The #BK auxiliary contact 27b is electrically connected to the door opening travel protection device 50 and the elevator operation control device 60, and a signal 27bA indicating the open / closed state of the #BK auxiliary contact 27b is opened. It is sent to the protection device 50 and the elevator operation control device 60.

Therefore, the door opening travel protection control unit 51 uses the signals 36A, 42A, and 37A to indicate that the car 31 that is being opened has moved out of the door opening allowable range, and that the car door 35 and the landing area while the car 31 is traveling. It can be detected that at least one of the door 41 and the door 41 is open. That is, the door-open travel protection device 50 can detect the door-open travel of the car 31. When the door open travel protection control unit 51 detects the door open travel of the car 31, the door open travel protection signal 51A is sent to the door open travel protection signal output circuit 54 (sends an ON signal).
　自己診断制御部５２は、＃ＭＣ補助接点１１ｂ及び＃ＢＫ補助接点２７ｂからの信号１１ｂＡ，２７ｂＡを用いて、＃ＭＣ主接点１１ａ及び＃ＢＫ主接点２７ａのそれぞれの開極・閉極の状態を監視する。また、自己診断制御部５２は、自己診断処理を実行可能になっている。この自己診断処理とは、戸開走行保護装置５０（戸開走行保護信号出力回路５４）が生成する戸開走行保護信号５０Ａによって主回路及びブレーキ装置２０への給電が正常に遮断されるか否かを判断するための処理である。 The self-diagnosis control unit 52 uses the signals 11bA and 27bA from the #MC auxiliary contact 11b and the #BK auxiliary contact 27b to determine the respective open / close states of the #MC main contact 11a and the #BK main contact 27a. Monitor. In addition, the self-diagnosis control unit 52 can execute self-diagnosis processing. This self-diagnosis process refers to whether or not the power supply to the main circuit and the brake device 20 is normally cut off by the door-open travel protection signal 50A generated by the door-open travel protection device 50 (door-open travel protection signal output circuit 54). This is a process for determining whether or not.
　さらに、自己診断制御部５２は、エレベータ運転制御装置６０から受けた自己診断実行許可信号６０ＣがＯＮである場合で、かつ自己診断タイマ５３が例えば２４時間以上である場合に自己診断処理を実行する。ここで、自己診断タイマ５３は、前回の自己診断処理の完了時からの経過時間を計測し、その経過時間が例えば２４時間以上とならないように自己診断処理の開始を自己診断制御部５２に通知する。 Furthermore, the self-diagnosis control unit 52 executes self-diagnosis processing when the self-diagnosis execution permission signal 60C received from the elevator operation control device 60 is ON and the self-diagnosis timer 53 is 24 hours or more, for example. . Here, the self-diagnosis timer 53 measures the elapsed time from the completion of the previous self-diagnosis process, and notifies the self-diagnosis control unit 52 of the start of the self-diagnosis process so that the elapsed time does not exceed 24 hours, for example. To do.
　また、自己診断制御部５２は、自己診断処理を実行する際に、エレベータ運転制御装置６０に対して、＃ＭＣ駆動指令５２Ａ及び＃ＢＫ駆動指令５２Ｂを送る。さらに、自己診断制御部５２は、自己診断処理を実行する際に、戸開走行保護信号出力回路５４に対して診断用戸開走行保護信号５２Ｃを送る。また、自己診断制御部５２は、自己診断処理が完了した際に、戸開走行保護制御部５１に対して自己診断結果の情報５２Ｄを送る。 Also, the self-diagnosis control unit 52 sends a #MC drive command 52A and a #BK drive command 52B to the elevator operation control device 60 when executing the self-diagnosis process. Furthermore, the self-diagnosis control unit 52 sends a diagnostic door-open travel protection signal 52C to the door-open travel protection signal output circuit 54 when executing the self-diagnosis process. In addition, the self-diagnosis control unit 52 sends self-diagnosis result information 52D to the door-opening travel protection control unit 51 when the self-diagnosis process is completed.
　戸開走行保護制御部５１は、自己診断結果の情報５２Ｄが戸開走行保護機能の動作異常を示している場合に、戸開走行保護信号出力回路５４に制御用戸開走行保護信号５１Ａを送る（ＯＮ信号を送る）。戸開走行保護信号出力回路５４は、制御用戸開走行保護信号５１Ａ及び診断用戸開走行保護信号５２Ｃの少なくともいずれか一方がＯＮであるときに、戸開走行保護信号５０Ａを遮断制御用論理回路７０に送る。 The door-opening travel protection control unit 51 sends a control door-opening travel protection signal 51A to the door-opening travel protection signal output circuit 54 when the information 52D of the self-diagnosis result indicates an abnormal operation of the door-opening travel protection function. (Send ON signal). The door-open travel protection signal output circuit 54 is configured to control the door-open travel protection signal 50A when the control door-open travel protection signal 51A or the diagnostic door-open travel protection signal 52C is ON. Send to circuit 70.
　エレベータ運転制御装置６０も、戸開走行保護装置５０と同様に、信号３６Ａ，４２Ａ，３７Ａ，１１ｂＡ，２７ｂＡを受けて、かごドア３５及び乗場ドア４１のそれぞれの開閉状態と、かご３１の位置が戸開許容範囲内であるか否かと、＃ＭＣ主接点１１ａ及び＃ＢＫ主接点２７ａのそれぞれの開極・閉極の状態とを監視する。 The elevator operation control device 60 receives the signals 36A, 42A, 37A, 11bA, and 27bA, and the open / closed states of the car door 35 and the landing door 41 and the position of the car 31 are the same as the door opening travel protection device 50. It is monitored whether it is within the door opening allowable range and the open / closed states of the #MC main contact 11a and the #BK main contact 27a.
　また、エレベータ運転制御装置６０は、かご３１の通常運転モードのときに、自身の判断に基づいて、主回路用電磁遮断器１１及びブレーキ用電磁遮断器２７のそれぞれの切換動作を決定する。そして、エレベータ運転制御装置６０は、その決定に対応する＃ＭＣ駆動信号６０Ａ及び＃ＢＫ駆動信号６０Ｂを生成し、その＃ＭＣ駆動信号６０Ａ及び＃ＢＫ駆動信号６０Ｂを遮断制御用論理回路７０に送る。 Further, when the car 31 is in the normal operation mode, the elevator operation control device 60 determines each switching operation of the main circuit electromagnetic circuit breaker 11 and the brake electromagnetic circuit breaker 27 based on its own determination. Then, the elevator operation control device 60 generates a #MC drive signal 60A and a #BK drive signal 60B corresponding to the determination, and sends the #MC drive signal 60A and #BK drive signal 60B to the cutoff control logic circuit 70. .
　ここで、エレベータ運転制御装置６０は、例えばかご３１の戸閉待機中の診断モードのときに、自己診断実行許可信号６０ＣをＯＮにする。なお、診断モードとは、戸開走行保護装置５０による自己診断処理の実行を許可しているときのエレベータ運転制御装置６０の制御モードである。 Here, the elevator operation control device 60 turns on the self-diagnosis execution permission signal 60C, for example, in the diagnosis mode when the car 31 is waiting for the door to be closed. The diagnosis mode is a control mode of the elevator operation control device 60 when the door-opening travel protection device 50 is permitted to execute the self-diagnosis process.
　エレベータ運転制御装置６０は、診断モードのときには、戸開走行保護装置５０からの＃ＭＣ駆動指令５２Ａに従って主回路用電磁遮断器１１の切換動作を決定する。そして、エレベータ運転制御装置６０は、その決定に対応する＃ＭＣ駆動信号６０Ａを生成し、その＃ＭＣ駆動信号６０Ａを遮断制御用論理回路７０に送る。 The elevator operation control device 60 determines the switching operation of the main circuit electromagnetic circuit breaker 11 according to the #MC drive command 52A from the door-opening travel protection device 50 in the diagnosis mode. Then, the elevator operation control device 60 generates a #MC drive signal 60A corresponding to the determination, and sends the #MC drive signal 60A to the cutoff control logic circuit 70.
　これと同様に、エレベータ運転制御装置６０は、診断モードのときには、戸開走行保護装置５０からの＃ＢＫ駆動指令５２Ｂに従ってブレーキ用電磁遮断器２７の切換動作を決定する。そして、エレベータ運転制御装置６０は、その決定に対応する＃ＢＫ駆動信号６０Ｂを生成し、その＃ＢＫ駆動信号６０Ｂを遮断制御用論理回路７０に送る。 Similarly, the elevator operation control device 60 determines the switching operation of the brake electromagnetic circuit breaker 27 according to the #BK drive command 52B from the door-opening travel protection device 50 in the diagnosis mode. Then, the elevator operation control device 60 generates a #BK drive signal 60B corresponding to the determination, and sends the #BK drive signal 60B to the cutoff control logic circuit 70.
　遮断制御用論理回路７０は、＃ＭＣ駆動電圧出力回路７１と、＃ＢＫ駆動電圧出力回路７２とを有している。＃ＭＣ駆動電圧出力回路７１は、戸開走行保護装置５０からの戸開走行保護信号５０Ａと、エレベータ運転制御装置６０からの＃ＭＣ駆動信号６０Ａとを受ける。また、＃ＭＣ駆動電圧出力回路７１は、戸開走行保護信号５０ＡがＯＦＦの場合で、かつ＃ＭＣ駆動信号６０ＡがＯＮの場合にのみ、＃ＭＣコイル１１ｃへ給電するためのトランジスタ素子８１に、＃ＭＣ駆動電圧７１Ａを印加する。 The cutoff control logic circuit 70 includes a #MC drive voltage output circuit 71 and a #BK drive voltage output circuit 72. The #MC drive voltage output circuit 71 receives the door open travel protection signal 50A from the door open travel protection device 50 and the #MC drive signal 60A from the elevator operation control device 60. In addition, the #MC drive voltage output circuit 71 has a transistor element 81 for supplying power to the #MC coil 11c only when the door-opening travel protection signal 50A is OFF and the #MC drive signal 60A is ON. #MC drive voltage 71A is applied.
　＃ＢＫ駆動電圧出力回路７２は、戸開走行保護装置５０からの戸開走行保護信号５０Ａと、エレベータ運転制御装置６０からの＃ＢＫ駆動信号６０Ｂとを受ける。また、＃ＢＫ駆動電圧出力回路７２は、戸開走行保護信号５０ＡがＯＦＦの場合で、かつ＃ＢＫ駆動信号６０ＢがＯＮの場合にのみ、＃ＢＫコイル２７ｃへ給電するためのトランジスタ素子８２に、＃ＢＫ駆動電圧７２Ａを印加する。 The #BK drive voltage output circuit 72 receives the door open travel protection signal 50A from the door open travel protection device 50 and the #BK drive signal 60B from the elevator operation control device 60. In addition, the #BK drive voltage output circuit 72 has a transistor element 82 for supplying power to the #BK coil 27c only when the door-opening travel protection signal 50A is OFF and the #BK drive signal 60B is ON. #BK drive voltage 72A is applied.
　従って、主回路用電磁遮断器１１及びブレーキ用電磁遮断器２７のそれぞれの切換動作は、かご３１の通常運転中には、エレベータ運転制御装置６０によって制御される。これに対して、主回路用電磁遮断器１１及びブレーキ用電磁遮断器２７のそれぞれの切換動作は、戸開走行保護装置５０（自己診断制御部５２）の自己診断処理中には、戸開走行保護装置５０によって制御される。つまり、主回路用電磁遮断器１１及びブレーキ用電磁遮断器２７の切換動作の制御の主体が、戸開走行保護装置５０及びエレベータ運転制御装置６０の一方から他方に切り換わる。 Therefore, the switching operation of the main circuit electromagnetic circuit breaker 11 and the brake electromagnetic circuit breaker 27 is controlled by the elevator operation control device 60 during the normal operation of the car 31. On the other hand, the switching operation of the main circuit electromagnetic circuit breaker 11 and the brake electromagnetic circuit breaker 27 is performed when the door is open during the self-diagnosis processing of the door-open travel protection device 50 (self-diagnosis control unit 52). It is controlled by the protection device 50. That is, the main subject of the switching operation of the main circuit electromagnetic circuit breaker 11 and the brake electromagnetic circuit breaker 27 is switched from one of the door opening travel protection device 50 and the elevator operation control device 60 to the other.
　ここで、戸開走行保護装置５０は、演算処理部（ＣＰＵ）、記憶部（ＲＯＭ、ＲＡＭ及びハードディスク等）及び信号入出力部を持ったハードウェア（図示せず）により構成されている。戸開走行保護装置５０のハードウェアの記憶部は、戸開走行保護制御部５１、自己診断制御部５２及び自己診断タイマ５３のそれぞれの機能を実現するためのプログラムを格納している。 Here, the door-opening travel protection device 50 is configured by hardware (not shown) having an arithmetic processing unit (CPU), a storage unit (ROM, RAM, hard disk, etc.) and a signal input / output unit. The hardware storage unit of the door-opening travel protection device 50 stores a program for realizing the functions of the door-opening travel protection control unit 51, the self-diagnosis control unit 52, and the self-diagnosis timer 53.
　また、エレベータ運転制御装置６０も、戸開走行保護装置５０と同様のハードウェア（図示せず）により構成されている。エレベータ運転制御装置６０のハードウェアの記憶部には、エレベータ運転制御装置６０の機能を実現するためのプログラムが格納されている。即ち、実施の形態１では、戸開走行保護装置５０及びエレベータ運転制御装置６０は、互いに異なるハードウェアによって構成されている。 Moreover, the elevator operation control device 60 is also configured by the same hardware (not shown) as the door-opening travel protection device 50. A program for realizing the functions of the elevator operation control device 60 is stored in the hardware storage unit of the elevator operation control device 60. That is, in the first embodiment, the door-opening travel protection device 50 and the elevator operation control device 60 are configured by different hardware.
　次に、自己診断制御部５２の自己診断処理について説明する。図３～６は、図２の自己診断制御部５２の自己診断処理を示すフローチャートである。なお、図４は、図３の♯ＭＣ遮断機能診断処理を示し、図５は、図３の＃ＢＫ遮断機能診断処理を示し、図６は、戸開走行保護機能診断処理を示す。ここで、自己診断制御部５２は、図３～６に示す処理を繰り返し実行する。 Next, the self-diagnosis process of the self-diagnosis control unit 52 will be described. 3 to 6 are flowcharts showing the self-diagnosis process of the self-diagnosis control unit 52 of FIG. 4 shows the #MC cutoff function diagnostic process of FIG. 3, FIG. 5 shows the #BK cutoff function diagnostic process of FIG. 3, and FIG. 6 shows the door-opening travel protection function diagnostic process. Here, the self-diagnosis control unit 52 repeatedly executes the processes shown in FIGS.
　図３において、自己診断制御部５２は、自己診断タイマ５３の値が２４時間以上であるか否か、及びエレベータ運転制御装置６０からの自己診断実行許可信号６０ＣがＯＮであるか否かを確認する（ステップＳ１００）。このときに、自己診断制御部５２は、自己診断タイマ５３の値が２４時間未満であること、及びエレベータ運転制御装置６０からの自己診断実行許可信号６０ＣがＯＦＦであることの少なくともいずれか一方を確認した場合に（ステップＳ１００のＮＯ方向）、ステップＳ１０１の処理を実行する。 In FIG. 3, the self-diagnosis control unit 52 confirms whether the value of the self-diagnosis timer 53 is 24 hours or more and whether the self-diagnosis execution permission signal 60C from the elevator operation control device 60 is ON. (Step S100). At this time, the self-diagnosis control unit 52 determines that the value of the self-diagnosis timer 53 is less than 24 hours and that the self-diagnosis execution permission signal 60C from the elevator operation control device 60 is OFF. When confirmed (NO direction of step S100), the process of step S101 is executed.
　そして、ステップＳ１０１では、自己診断制御部５２は、＃ＭＣ駆動指令５２Ａ、＃ＢＫ駆動指令５２Ｂ、及び診断用戸開走行保護信号５２ＣをいずれもＯＦＦに設定する。この後、自己診断制御部５２は、各自己診断ステートの値を初期化し（ステップＳ１０２）、ステップＳ１００の処理を再度実行する。 In step S101, the self-diagnosis control unit 52 sets the #MC drive command 52A, the #BK drive command 52B, and the diagnostic door open travel protection signal 52C to OFF. Thereafter, the self-diagnosis control unit 52 initializes the value of each self-diagnosis state (step S102), and executes the process of step S100 again.
　他方、自己診断制御部５２は、自己診断タイマ５３の値が２４時間以上であること、及びエレベータ運転制御装置６０からの自己診断実行許可信号がＯＮであることの両方を確認した場合に（ステップＳ１００のＹＥＳ方向）、自己診断処理を開始し、ステップＳ１０３の処理を実行する。そして、ステップＳ１０３では、自己診断制御部５２は、自己診断ステート（ｓｔ＿ｄｉａｇ）の値を確認する。 On the other hand, the self-diagnosis control unit 52 confirms both that the value of the self-diagnosis timer 53 is 24 hours or more and that the self-diagnosis execution permission signal from the elevator operation control device 60 is ON (step In the YES direction of S100), the self-diagnosis process is started, and the process of step S103 is executed. In step S103, the self-diagnosis control unit 52 confirms the value of the self-diagnosis state (st_diag).
　このときに、自己診断制御部５２は、自己診断ステートの値が０～２以外の値であることを確認した場合には、ステップＳ１１０の処理を実行する。ステップＳ１１０では、自己診断制御部５２は、自己診断ステートの値を初期化する（ｓｔ＿ｄｉａｇ＝０）。そして、自己診断制御部５２は、ステップＳ１００の処理を再度実行する。 At this time, if the self-diagnosis control unit 52 confirms that the value of the self-diagnosis state is a value other than 0 to 2, it executes the process of step S110. In step S110, the self-diagnosis control unit 52 initializes the value of the self-diagnosis state (st_diag = 0). And the self-diagnosis control part 52 performs the process of step S100 again.
　また、ステップＳ１０３において、自己診断制御部５２は、自己診断ステートの値が０であることを確認した場合には（ｓｔ＿ｄｉａｇ＝０）、＃ＭＣ遮断機能診断モードの処理へ移行する。＃ＭＣ遮断機能診断モードでは、自己診断制御部５２は、＃ＭＣ遮断機能診断が完了しているか否かを確認する（ステップＳ１０４）。 In step S103, when the self-diagnosis control unit 52 confirms that the value of the self-diagnosis state is 0 (st_diag = 0), the self-diagnosis control unit 52 proceeds to processing of the #MC cutoff function diagnosis mode. In the #MC cutoff function diagnosis mode, the self-diagnosis control unit 52 checks whether or not #MC cutoff function diagnosis is completed (step S104).
　このときに、自己診断制御部５２は、＃ＭＣ遮断機能診断が完了していないことを確認した場合には、ステップＳ２００の処理、即ち＃ＭＣ遮断機能診断処理を実行し、その後、ステップＳ１００の処理を再度実行する。 At this time, if the self-diagnosis control unit 52 confirms that the #MC cutoff function diagnosis has not been completed, the self-diagnosis control unit 52 executes the process of step S200, that is, the #MC cutoff function diagnostic process, and then the process of step S100. Run the process again.
　ここで、自己診断制御部５２は、ステップＳ２００の＃ＭＣ遮断機能診断処理として、図４に示す処理を実行する。図４のステップＳ２０１では、自己診断制御部５２は、＃ＭＣ遮断機能診断ステートの値を確認する。このときに、自己診断制御部５２は、＃ＭＣ遮断機能診断ステートの値が０～５以外の値であることを確認した場合には、＃ＭＣ遮断機能診断ステートの値を０に更新し（ｓｔ＿ｍｃ＝０：ステップＳ２２０）、ステップＳ２０１の処理を再度実行する。 Here, the self-diagnosis control unit 52 executes the process shown in FIG. 4 as the #MC cutoff function diagnosis process in step S200. In step S201 of FIG. 4, the self-diagnosis control unit 52 confirms the value of the #MC cutoff function diagnostic state. At this time, if the self-diagnosis control unit 52 confirms that the value of the #MC cutoff function diagnostic state is a value other than 0 to 5, it updates the value of the #MC cutoff function diagnostic state to 0 ( st_mc = 0: Step S220), the process of Step S201 is executed again.
　ステップＳ２０１において、自己診断制御部５２は、＃ＭＣ遮断機能診断ステートの値が０であることを確認した場合には、ＭＣ遮断機能診断ステート０の処理へ移行する。ＭＣ遮断機能診断ステート０では、自己診断制御部５２は、タイマを初期化し（ステップＳ２０２）、＃ＭＣ遮断機能診断ステートの値を１に更新して、＃ＭＣ遮断機能診断ステート１（ｓｔ＿ｍｃ＝１）の処理へ移行する（ステップＳ２０３）。 In step S201, when the self-diagnosis control unit 52 confirms that the value of the #MC cutoff function diagnostic state is 0, the self-diagnosis control unit 52 proceeds to processing of the MC cutoff function diagnostic state 0. In the MC cutoff function diagnostic state 0, the self-diagnosis control unit 52 initializes the timer (step S202), updates the value of the #MC cutoff function diagnostic state to 1, and #MC cutoff function diagnostic state 1 (st_mc = 1) ) (Step S203).
　そして、＃ＭＣ遮断機能診断ステート１では、自己診断制御部５２は、♯ＭＣ駆動指令５２ＡをＯＮとし（ステップＳ２０４）、♯ＭＣ補助接点入力の信号１１ｂＡがＯＦＦになるまで待機する（ステップＳ２０５）。即ち、自己診断制御部５２は、＃ＭＣ主接点２７ａの状態が実際に切り換わるまで待機する。そして、自己診断制御部５２は、＃ＭＣ補助接点入力の信号１１ｂＡがＯＦＦになったことを確認すると、＃ＭＣ遮断機能診断ステートの値を２に更新して、＃ＭＣ遮断機能診断ステート２（ｓｔ＿ｍｃ＝２）の処理へ移行する（ステップＳ２０６）。 In #MC cutoff function diagnostic state 1, the self-diagnosis control unit 52 turns on the #MC drive command 52A (step S204), and waits until the signal 11bA of the #MC auxiliary contact input is turned off (step S205). . That is, the self-diagnosis control unit 52 stands by until the state of the #MC main contact 27a is actually switched. When the self-diagnosis control unit 52 confirms that the #MC auxiliary contact input signal 11bA is OFF, the self-diagnosis control unit 52 updates the value of the #MC cutoff function diagnostic state to 2, and the #MC cutoff function diagnostic state 2 ( The process proceeds to st_mc = 2) (step S206).
　＃ＭＣ遮断機能診断ステート２では、自己診断制御部５２は、診断用戸開走行保護信号５２ＣをＯＮとし（ステップＳ２０７）、＃ＭＣ遮断機能診断ステートの値を３に更新して、＃ＭＣ遮断機能診断ステート３（ｓｔ＿ｍｃ＝３）の処理へ移行する（ステップＳ２０８）。 In #MC cutoff function diagnostic state 2, the self-diagnosis control unit 52 turns ON the diagnostic door open travel protection signal 52C (step S207), updates the value of the #MC cutoff function diagnostic state to 3, and #MC cutoff The process proceeds to the function diagnosis state 3 (st_mc = 3) (step S208).
　＃ＭＣ遮断機能診断ステート３では、自己診断制御部５２は、タイマカウントアップを行い（ｔｉｍｅｒ＝ｔｉｍｅｒ＋１）、タイマの値が所定のシステム応答時間Ｔ＿ｒｅｓを超過するまで、タイマカウントアップを行う（ステップＳ２０９，Ｓ２１０）。そして、自己診断制御部５２は、タイマの値が所定のシステム応答時間Ｔ＿ｒｅｓを超過したことを確認した場合には、＃ＭＣ遮断機能診断ステートの値を４に更新して、＃ＭＣ遮断機能診断ステート４（ｓｔ＿ｍｃ＝４）の処理へ移行する（ステップＳ２１１）。 In #MC cutoff function diagnostic state 3, the self-diagnosis control unit 52 counts up the timer (timer = timer + 1), and counts up the timer until the timer value exceeds a predetermined system response time T_res (step S209). , S210). When the self-diagnosis control unit 52 confirms that the timer value has exceeded the predetermined system response time T_res, the self-diagnosis control unit 52 updates the value of the #MC cutoff function diagnosis state to 4, and the #MC cutoff function diagnosis The process proceeds to the state 4 (st_mc = 4) process (step S211).
　なお、システム応答時間Ｔ＿ｒｅｓとは、戸開走行保護装置５０が正常な場合において、診断用戸開走行保護信号５２ＣがＯＮとなってから、モータ１３への給電と、第１ブレーキコイル２３及び第２ブレーキコイル２４への給電とが遮断されるまでの応答時間である。また、システム応答時間Ｔ＿ｒｅｓは、事前に自己診断制御部５２に登録されている。 The system response time T_res refers to the power supply to the motor 13, the first brake coil 23 and the first brake coil 23 after the diagnostic door open travel protection signal 52C is turned on when the door open travel protection device 50 is normal. 2 Response time until power supply to the brake coil 24 is cut off. The system response time T_res is registered in the self-diagnosis control unit 52 in advance.
　そして、＃ＭＣ遮断機能診断ステート４では、自己診断制御部５２は、♯ＭＣ補助接点入力の信号１１ｂＡがＯＮであるか否かを確認する（ステップＳ２１２）。このときに、自己診断制御部５２は、♯ＭＣ補助接点入力の信号１１ｂＡがＯＮであることを確認すると、♯ＭＣ遮断機能動作が正常であると診断し（ステップＳ２１３）、＃ＭＣ遮断機能診断ステートの値を５に更新して、＃ＭＣ遮断機能診断ステート５（ｓｔ＿ｍｃ＝５）の処理へ移行する（ステップＳ２１５）。 In #MC cutoff function diagnosis state 4, the self-diagnosis control unit 52 checks whether or not the signal 11bA for #MC auxiliary contact input is ON (step S212). At this time, when the self-diagnosis control unit 52 confirms that the #MC auxiliary contact input signal 11bA is ON, it diagnoses that the #MC cutoff function operation is normal (step S213), and #MC cutoff function diagnosis The state value is updated to 5, and the process proceeds to #MC cutoff function diagnostic state 5 (st_mc = 5) (step S215).
　他方、自己診断制御部５２は、♯ＭＣ補助接点入力の信号１１ｂＡがＯＦＦであることを確認すると、♯ＭＣ遮断機能動作が異常であると診断し（ステップＳ２１４）、＃ＭＣ遮断機能診断ステートの値を５に更新して、＃ＭＣ遮断機能診断ステート５（ｓｔ＿ｍｃ＝５）の処理へ移行する（ステップＳ２１５）。 On the other hand, when the self-diagnosis control unit 52 confirms that the signal 11bA of the #MC auxiliary contact input is OFF, it diagnoses that the #MC cutoff function operation is abnormal (step S214), and enters the #MC cutoff function diagnostic state. The value is updated to 5, and the process proceeds to #MC cutoff function diagnostic state 5 (st_mc = 5) (step S215).
　そして、＃ＭＣ遮断機能診断ステート５では、自己診断制御部５２は、♯ＭＣ駆動指令５２ＡをＯＦＦとするとともに、診断用戸開走行保護信号５２ＣをＯＦＦとし（ステップＳ２０６）、♯ＭＣ遮断機能診断が完了したことを記憶する（ステップＳ２１７）。そして、自己診断制御部５２は、図３におけるステップＳ１００，Ｓ１０４の処理を再度実行する。この後、自己診断制御部５２は、自己診断ステートの値を１に更新し（ｓｔ＿ｄｉａｇ＝１：ステップＳ１０５）、＃ＢＫ遮断機能診断モード（ｓｔ＿ｄｉａｇ＝１）に移行する。 In the #MC cutoff function diagnostic state 5, the self-diagnosis control unit 52 turns off the #MC drive command 52A and turns off the diagnostic door open travel protection signal 52C (step S206). Is completed (step S217). And the self-diagnosis control part 52 performs the process of step S100, S104 in FIG. 3 again. Thereafter, the self-diagnosis control unit 52 updates the value of the self-diagnosis state to 1 (st_diag = 1: step S105), and shifts to the #BK cutoff function diagnosis mode (st_diag = 1).
　＃ＢＫ遮断機能診断モードでは、自己診断制御部５２は、＃ＢＫ遮断機能診断が完了しているか否かを確認する（ステップＳ１０６）。このときに、自己診断制御部５２は、＃ＭＣ遮断機能診断が完了していないことを確認した場合には、ステップＳ３００の処理、即ち＃ＢＫ遮断機能診断処理を実行し、その後、ステップＳ１００の処理を再度実行する。 In the #BK blocking function diagnosis mode, the self-diagnosis control unit 52 confirms whether or not #BK blocking function diagnosis has been completed (step S106). At this time, if the self-diagnosis control unit 52 confirms that the #MC cutoff function diagnosis has not been completed, the self-diagnosis control unit 52 executes the process of step S300, that is, the #BK cutoff function diagnostic process, and then the process of step S100. Run the process again.
　ここで、自己診断制御部５２は、ステップＳ３００の＃ＢＫ遮断機能診断処理として、図５に示す処理を実行する。この図５に示す＃ＢＫ遮断機能診断処理の手順は、図４に示す＃ＭＣ遮断機能診断処理の手順と同様である。そして、自己診断制御部５２は、＃ＢＫ遮断機能診断が完了したことを確認すると、自己診断ステートの値を２に更新し（ｓｔ＿ｄｉａｇ＝２：ステップＳ１０７）、戸開走行保護機能診断モード（ｓｔ＿ｄｉａｇ＝２）に移行する。 Here, the self-diagnosis control unit 52 executes the process shown in FIG. 5 as the #BK blocking function diagnosis process in step S300. The procedure of the #BK blocking function diagnosis process shown in FIG. 5 is the same as the procedure of the #MC blocking function diagnosis process shown in FIG. When the self-diagnosis control unit 52 confirms that the #BK blocking function diagnosis is completed, the self-diagnosis control unit 52 updates the value of the self-diagnosis state to 2 (st_diag = 2: step S107), and the door-opening travel protection function diagnosis mode (st_diag). = 2).
　戸開走行保護機能診断モードでは、自己診断制御部５２は、ステップＳ４００の戸開走行保護機能診断処理を実行する。ここで、自己診断制御部５２は、ステップＳ４００の＃戸開走行保護機能診断処理として、図６に示す処理を実行する。 In the door-opening travel protection function diagnosis mode, the self-diagnosis control unit 52 executes the door-opening travel protection function diagnosis process in step S400. Here, the self-diagnosis control unit 52 executes the process shown in FIG. 6 as the # door-opening travel protection function diagnosis process in step S400.
　図６のステップＳ４０１では、自己診断制御部５２は、＃ＭＣ遮断機能及び＃ＢＫ遮断機能の両方の機能の動作が正常であるか否かを確認する。このときに、自己診断制御部５２は、＃ＭＣ遮断機能及び＃ＢＫ遮断機能の少なくともいずれか一方の機能の動作が異常であることを確認した場合には、戸開走行保護機能の動作が異常であると判断する（ステップＳ４０２）。 In step S401 of FIG. 6, the self-diagnosis control unit 52 confirms whether the operations of both the #MC cutoff function and the #BK cutoff function are normal. At this time, if the self-diagnosis control unit 52 confirms that the operation of at least one of the #MC blocking function and the #BK blocking function is abnormal, the operation of the door opening traveling protection function is abnormal. (Step S402).
　そして、自己診断制御部５２は、作業員による所定のリセット操作を受けるまで待機する（ステップＳ４０３）。即ち、自己診断制御部５２は、エレベータ装置を休止させるために、戸開走行保護機能の動作異常が修復されるまで待機する。この後、自己診断制御部５２は、リセット操作を受けると、ステップＳ４０５の処理を実行する。 Then, the self-diagnosis control unit 52 waits until receiving a predetermined reset operation by the worker (step S403). That is, the self-diagnosis control unit 52 stands by until the operation abnormality of the door-opening travel protection function is repaired in order to pause the elevator apparatus. Thereafter, when receiving a reset operation, the self-diagnosis control unit 52 executes the process of step S405.
　他方、自己診断制御部５２は、＃ＭＣ遮断機能及び＃ＢＫ遮断機能の両方の機能の動作が正常であることを確認した場合には（ステップＳ４０１のＮＯ方向）、戸開走行保護機能の動作が正常であると判断する（ステップＳ４０４）。この後、自己診断制御部５２は、ステップＳ４０５の処理を実行する。 On the other hand, when the self-diagnosis control unit 52 confirms that the operations of both the #MC blocking function and the #BK blocking function are normal (NO direction in step S401), the operation of the door open traveling protection function is performed. Is determined to be normal (step S404). Thereafter, the self-diagnosis control unit 52 executes the process of step S405.
　ステップＳ４０５において、自己診断制御部５２は、＃ＭＣ遮断機能診断及び＃ＢＫ遮断機能診断を未完了として記憶し（ステップＳ４０５）、自己診断タイマ５３の値をゼロクリアする（Ｓ４０６）。以上により、自己診断制御部５２の自己診断が完了する。 In step S405, the self-diagnosis control unit 52 stores #MC cutoff function diagnosis and #BK cutoff function diagnosis as incomplete (step S405), and clears the value of the self-diagnosis timer 53 to zero (S406). Thus, the self-diagnosis of the self-diagnosis control unit 52 is completed.
　上記のような実施の形態１のエレベータ装置によれば、エレベータ運転制御装置６０は、診断モードのときには、戸開走行保護装置５０からの＃ＭＣ駆動指令５２Ａに従って主回路用電磁遮断器１１の切換動作を決定する。また、エレベータ運転制御装置６０は、診断モードのときには、戸開走行保護装置５０からの＃ＢＫ駆動指令５２Ｂに従ってブレーキ用電磁遮断器２７の切換動作を決定する。この構成により、戸開走行保護装置５０及びエレベータ運転制御装置６０が共同して主回路用電磁接触器１１及びブレーキ用電磁接触器２７の切換動作を制御することができる。 According to the elevator apparatus of the first embodiment as described above, the elevator operation control apparatus 60 switches the main circuit electromagnetic circuit breaker 11 according to the #MC drive command 52A from the door opening travel protection apparatus 50 in the diagnosis mode.

Send to. Then, when the door opening travel protection device 50 confirms the shut-off operation by the electromagnetic contactors 11 and 27 based on the state of the auxiliary contacts 11b and 27b of the electromagnetic contactors 11 and 27, the door opening travel protection device 50 It can be determined that the power supply cutoff function to the brake device 20 is operating normally. Moreover, the door-opening travel protection device 50 can determine that the operation is abnormal when it is confirmed that the blocking operation by the electromagnetic contactors 11 and 27 has not occurred.
　さらに、戸開走行保護装置５０は、自己診断処理を定期的に実行するので、♯ＭＣ遮断機能及び♯ＢＫ遮断機能の異常を比較的早期に検出することができる。 Furthermore, since the door-opening travel protection device 50 periodically executes self-diagnosis processing, it is possible to detect an abnormality in the #MC cutoff function and the #BK cutoff function relatively early.
