Description

エレベータ用ガバナシステムの検査装置および検査方法Inspection device and method for elevator governor system
　本発明は、エレベータ用非常止め装置を作動させるエレベータ用ガバナシステムの動作を検査する検査装置および検査方法に関する。 The present invention relates to an inspection device and an inspection method for inspecting the operation of an elevator governor system that operates an elevator emergency stop device.
　エレベータ装置には、乗りかごの昇降速度を常時監視して、所定の過速状態に陥った乗りかごを非常停止させるために、ガバナおよび非常止め装置が備えられている。ガバナのプーリには、乗りかごに結合されたガバナロープが巻き掛けられている。乗りかごが昇降すると、乗りかごとともにガバナロープが動くため、プーリが回転する。プーリが回転すると、プーリに設けられている振子が、遠心力によって振れる。乗りかごが過速状態となり振子の振れが大きくなると、振子によってガバナロープの把持機構が作動し、ガバナロープの動きが拘束される。これにより、乗りかご側の非常止め装置が作動し、乗りかごが非常停止する。 Elevator equipment is equipped with a governor and an emergency stop device to constantly monitor the elevator car's elevator speed and bring the elevator car to an emergency stop when it reaches a predetermined overspeed condition. A governor rope connected to the cage is wound around the governor pulley. When the car moves up and down, the governor rope moves with the car, causing the pulley to rotate. When the pulley rotates, the pendulum attached to the pulley swings due to centrifugal force. When the car is in an overspeed state and the swing of the pendulum becomes large, the pendulum activates a gripping mechanism for the governor rope, and the movement of the governor rope is restricted. This activates the emergency stop device on the car side, causing the car to come to an emergency stop.
　このようなエレベータ装置では、昇降路内に長尺物であるガバナロープを敷設するため、省スペース化および低コスト化が難しい。また、ガバナロープが振れる場合、昇降路内における構造物とガバナロープとが干渉しやすくなる。 In such an elevator system, since a long governor rope is laid in the hoistway, it is difficult to save space and reduce costs. Further, when the governor rope swings, structures in the hoistway and the governor rope tend to interfere with each other.
　これに対し、上述のような機械的なガバナを用いず、非接触センサを用いて検出される乗りかごの速度に基づいて非常止め装置を作動させる従来技術として、特許文献１に記載された技術が知られている。 On the other hand, as a conventional technique that operates an emergency stop device based on the speed of the car detected using a non-contact sensor without using a mechanical governor as described above, there is a technique described in Patent Document 1. It has been known.
　本従来技術では、監視装置が、乗りかごの位置と速度を検出する検出手段におけるかご速度検出部からの速度情報に基づいて運転状況に異常があると判断すると、非常止め装置に作動信号を出力する。また、特許文献１（図１５）に記載される移動体の位置・速度検出装置は、移動体が備えるカメラによって撮影される画像に基づいて、移動体の速度を検出する。移動体がエレベータである場合、昇降路の壁や柱が撮影される。 In this conventional technology, when the monitoring device determines that there is an abnormality in the driving situation based on speed information from the car speed detection section in the detection means that detects the position and speed of the car, it outputs an activation signal to the emergency stop device. do. Furthermore, the position/speed detection device for a moving object described in Patent Document 1 (FIG. 15) detects the speed of the moving object based on an image taken by a camera included in the moving object. If the moving object is an elevator, the walls and pillars of the hoistway are photographed.

　機械式ガバナの動作の検査では、プーリからガバナロープを外して、駆動装置によりプーリを回転させることにより、乗りかごを走行させずに、検査を行うことができる。しかし、非接触センサを用いて乗りかごの速度を検出するガバナシステムでは、乗りかごを加速走行させて過速状態にする必要があり、検査が煩雑になったり、検査時間が長くなったりする。 When inspecting the operation of a mechanical governor, the governor rope is removed from the pulley and the pulley is rotated by the drive device, thereby making it possible to inspect the operation without running the car. However, in a governor system that detects the speed of a car using a non-contact sensor, it is necessary to accelerate the car to bring it into an overspeed state, which makes the inspection complicated and takes a long time.
　そこで、本発明は、非接触センサを用いて乗りかごの速度を検出するガバナシステムの動作を容易に検査することができる、エレベータ用ガバナシステムの検査装置および検査方法を提供する。 Therefore, the present invention provides an elevator governor system inspection device and inspection method that can easily inspect the operation of a governor system that detects the speed of a car using a non-contact sensor.
　上記課題を解決するために、本発明によるエレベータ用ガバナシステムの検査装置は、乗りかごに設けられる非接触センサと、非接触センサのセンサ信号に基づいて乗りかごの速度を検出し、検出速度に基づいて乗りかごの過速状態を判定すると、非常止め装置を動作させる安全制御装置とを備えるガバナシステムの動作を検査するものであって、検出速度に基づいて、検出速度よりも大きな模擬速度を生成する模擬速度生成部を備え、検査時に、安全制御装置は、模擬速度に基づいて乗りかごの過速状態を判定する。 In order to solve the above problems, an inspection device for an elevator governor system according to the present invention detects the speed of the car based on a non-contact sensor provided in the car and a sensor signal of the non-contact sensor. If the overspeed state of the car is determined based on the detected speed, the operation of the governor system, which is equipped with a safety control device that operates an emergency stop device, is tested, and based on the detected speed, a simulated speed larger than the detected speed is The safety control device includes a simulated speed generation unit that generates a simulated speed, and during an inspection, the safety control device determines an overspeed state of the car based on the simulated speed.

　以下、本発明の実施形態について、実施例により、図面を用いながら説明する。なお、各図において、参照番号が同一のものは同一の構成要件あるいは類似の機能を備えた構成要件を示している。 Hereinafter, embodiments of the present invention will be described by way of examples and with reference to the drawings. In each figure, the same reference numbers indicate the same constituent elements or constituent elements with similar functions.
　図１は、本発明の一実施例であるエレベータ装置の概略構成図である。 FIG. 1 is a schematic configuration diagram of an elevator system that is an embodiment of the present invention.
　図１に示すように、エレベータ装置は、乗りかご１と、非接触センサ２と、電動操作器３と、リンク機構４と、非常止め装置５とを備えている。図１では、非常止め装置５は簡略に図示し、非常止め装置５の詳細な構成については省略している。なお、本実施例における非常止め装置５は、公知技術によるものである。 As shown in FIG. 1, the elevator system includes a car 1, a non-contact sensor 2, an electric operating device 3, a link mechanism 4, and an emergency stop device 5. In FIG. 1, the emergency stop device 5 is simply illustrated, and the detailed configuration of the emergency stop device 5 is omitted. The emergency stop device 5 in this embodiment is based on a known technique.
　乗りかご１は、建築物に設けられる昇降路内に主ロープ（図示せず）により吊られており、ガイド装置を介してガイドレール７に摺動可能に係合している。駆動装置（巻上機：図示せず）により主ロープが摩擦駆動されると、乗りかご１は昇降路内を昇降する。 The car 1 is suspended by a main rope (not shown) in a hoistway provided in a building, and is slidably engaged with a guide rail 7 via a guide device. When the main rope is frictionally driven by a drive device (a hoisting machine, not shown), the car 1 moves up and down within the hoistway.
　非接触センサ２は、乗りかご１に設けられている。非接触センサ２を用いて、昇降路内における乗りかご１の位置が検出されるとともに、検出された乗りかご１の位置から乗りかご１の昇降速度が常時検出される。したがって、非接触センサ２を用いて、乗りかごの昇降速度が所定の過速度を超えたことを検出することができる。 The non-contact sensor 2 is provided in the car 1. Using the non-contact sensor 2, the position of the car 1 in the hoistway is detected, and the ascending and descending speed of the car 1 is constantly detected from the detected position of the car 1. Therefore, using the non-contact sensor 2, it is possible to detect that the lifting speed of the car exceeds a predetermined overspeed.
　本実施例では、非接触センサ２は、画像センサを備え、画像センサによって取得されるガイドレール７の表面状態の画像情報に基づいて、乗りかご１の位置および速度を検出する。 In this embodiment, the non-contact sensor 2 includes an image sensor and detects the position and speed of the car 1 based on image information of the surface state of the guide rail 7 acquired by the image sensor.
　電動操作器３は、本実施例１では電磁操作器であり、乗りかご１の上部に配置される。電磁操作器は、例えば、ソレノイドもしくは電磁石によって駆動される、可動片もしくは可動杆を備えるものである。電動操作器３は、電磁石を備え、電磁石が通電中は、非作動状態である。非接触センサ２によって乗りかご１の所定の過速状態が検出されると、電磁石の電源が遮断される。これにより、電動操作器３は、作動して、リンク機構４を変位させて非常止め装置５を制動状態にする。 The electric operating device 3 is an electromagnetic operating device in the first embodiment, and is arranged at the top of the car 1. The electromagnetic operating device includes a movable piece or a movable rod that is driven by, for example, a solenoid or an electromagnet. The electric operating device 3 includes an electromagnet, and is in an inactive state while the electromagnet is energized. When a predetermined overspeed state of the car 1 is detected by the non-contact sensor 2, the power to the electromagnet is cut off. As a result, the electric operating device 3 is actuated to displace the link mechanism 4 and put the emergency stop device 5 into a braking state.
　リンク機構４は、電動操作器３によって駆動されるリンクシャフト４０、リンクシャフト４０に連動可能にリンクする引き上げリンク４１、および引き上げリンク４１に連結される引き上げロッド４２を有しており、電動操作器３の作動に応じて引き上げリンク４１を介して乗りかご１の左右に配置された引き上げロッド４２を略同時に引き上げる。これにより、引き上げロッド４２に取り付けられる、非常止め装置５の制動子５１が、制動位置まで引き上げられると、制動子５１はガイドレール７を挟持する。 The link mechanism 4 includes a link shaft 40 driven by the electric actuator 3, a pull-up link 41 operatively linked to the link shaft 40, and a pull-up rod 42 connected to the pull-up link 41. 3, the pulling rods 42 disposed on the left and right sides of the car 1 are pulled up substantially simultaneously via the pulling links 41. As a result, when the brake 51 of the emergency stop device 5 attached to the pulling rod 42 is pulled up to the braking position, the brake 51 clamps the guide rail 7 .
　非常止め装置５は、乗りかご１の左右に一台ずつ配置される。非常止め装置５が備える制動子５１は、制動位置および非制動位置の間で可動であり、制動位置においてガイドレール７を挟持する。ガイドレール７を挟持した制動子５１が、乗りかご１の下降により乗りかご１に対して相対的に上昇すると、制動子５１とガイドレール７との間に作用する摩擦力により制動力を生じる。これにより、非常止め装置５は、乗りかご１が過速状態に陥ったときに作動し、乗りかご１を非常停止する。 The emergency stop devices 5 are arranged one on each side of the car 1. The brake element 51 included in the emergency stop device 5 is movable between a braking position and a non-braking position, and clamps the guide rail 7 in the braking position. When the brake element 51 holding the guide rail 7 rises relative to the car 1 due to the lowering of the car 1, a braking force is generated by the frictional force acting between the brake element 51 and the guide rail 7. Thereby, the emergency stop device 5 is activated when the car 1 falls into an overspeed state, and brings the car 1 to an emergency stop.
　本実施例のエレベータ装置は、ガバナロープを用いない、いわゆるロープレスガバナシステムを備える。ロープレスガバナシステムは、乗りかご１の昇降速度が定格速度を超えて第１過速度（例えば、定格速度の１．３倍を超えない速度）に達すると、主ロープが巻き掛けられるトラクションシーブを駆動する駆動装置（巻上機）の電源およびこの駆動装置を制御する制御装置の電源を遮断する。また、ロープレスガバナシステムは、乗りかご１の下降速度が第２過速度（例えば、定格速度の１．４倍を超えない速度）に達すると、乗りかご１に設けられる電動操作器３を電気的に駆動して、非常止め装置５を作動させて、乗りかご１を非常停止する。 The elevator apparatus of this embodiment includes a so-called ropeless governor system that does not use a governor rope. In the ropeless governor system, when the lifting speed of the car 1 exceeds the rated speed and reaches the first overspeed (for example, a speed not exceeding 1.3 times the rated speed), the traction sheave around which the main rope is wound is activated. Cut off the power to the drive device (hoisting machine) and the control device that controls this drive device. In addition, in the ropeless governor system, when the descending speed of the car 1 reaches a second overspeed (for example, a speed that does not exceed 1.4 times the rated speed), the electric operating device 3 provided in the car 1 is activated. The emergency stop device 5 is actuated to bring the car 1 to an emergency stop.
　本実施例において、ロープレスガバナシステムは、非接触センサ２と、非接触センサ２の出力信号に基づいて、乗りかご１の過速状態を判定する安全制御装置１００（図１）とから構成される。本実施例において、図１に示すように、安全制御装置１００は乗りかご１上に設けられる。 In this embodiment, the ropeless governor system includes a non-contact sensor 2 and a safety control device 100 (FIG. 1) that determines the overspeed state of the car 1 based on the output signal of the non-contact sensor 2. Ru. In this embodiment, a safety control device 100 is provided on a car 1, as shown in FIG.
　安全制御装置１００は、非接触センサ２のセンサ信号に基づいて乗りかご１の速度を計測し、計測された速度が第１過速度に達したと判定すると、駆動装置（巻上機）の電源およびこの駆動装置を制御する制御装置の電源を遮断するための指令信号を出力する。また、安全制御装置１００は、計測された速度が第２過速度に達したと判定すると、電動操作器３を駆動するための指令信号を出力する。 The safety control device 100 measures the speed of the car 1 based on the sensor signal of the non-contact sensor 2, and when it is determined that the measured speed has reached the first overspeed, the safety control device 100 turns on the power source of the drive device (hoisting machine). and outputs a command signal to cut off the power to the control device that controls this drive device. Furthermore, when the safety control device 100 determines that the measured speed has reached the second overspeed, it outputs a command signal for driving the electric operating device 3.
　後述するように、安全制御装置１００は、非接触センサ２を用いて乗りかご１の速度を検出するロープレスガバナシステムの動作を検査する機能を備えている。 As will be described later, the safety control device 100 has a function of inspecting the operation of the ropeless governor system that detects the speed of the car 1 using the non-contact sensor 2.
　図２は、本実施例におけるロープレスガバナシステムの構成を示す機能ブロック図である。 FIG. 2 is a functional block diagram showing the configuration of the ropeless governor system in this embodiment.
　安全制御装置１００は、速度検出部１０１と、模擬速度生成部１０２と、検査モード検出部１０５と、検査モード切替部１０６と、過速度判定部１０７と、駆動電源遮断指令部１０８と、電磁石電源遮断指令部１０９とを備えている。 The safety control device 100 includes a speed detection section 101, a simulated speed generation section 102, an inspection mode detection section 105, an inspection mode switching section 106, an overspeed determination section 107, a drive power cutoff command section 108, and an electromagnet power supply. A cutoff command section 109 is provided.
　本実施例において、安全制御装置１００はマイクロコンピュータなどのコンピュータシステムを備え、コンピュータシステムが、所定のプログラムを実行することにより、各部として動作する。 In this embodiment, the safety control device 100 includes a computer system such as a microcomputer, and the computer system operates as each part by executing a predetermined program.
　まず、ロープレスガバナシステムの通常動作であるガバナとしての動作について説明する。 First, the operation as a governor, which is the normal operation of the ropeless governor system, will be explained.
　速度検出部１０１は、非接触センサ２からのセンサ信号を取得し、取得したセンサ信号に基づいて、画像信号処理により、乗りかご１の速度を検出する。 The speed detection unit 101 acquires a sensor signal from the non-contact sensor 2, and detects the speed of the car 1 by image signal processing based on the acquired sensor signal.
　例えば、速度検出部１０１は、ガイドレール７の表面状態の画像特徴量の所定時間における移動距離から速度を算出する。また、例えば、速度検出部１０１は、予め記憶装置に記憶されるガイドレール７の表面状態の画像情報と、センサ信号から得られる画像情報を照合することにより、乗りかご１の位置を検出し、さらに、検出位置の時間変化を算出することにより乗りかご１の速度を計測する。 For example, the speed detection unit 101 calculates the speed from the moving distance of the image feature amount of the surface state of the guide rail 7 in a predetermined time. Further, for example, the speed detection unit 101 detects the position of the car 1 by comparing image information of the surface state of the guide rail 7 stored in the storage device in advance with image information obtained from the sensor signal, Furthermore, the speed of the car 1 is measured by calculating the temporal change in the detected position.
　速度検出部１０１は、乗りかご１の検出速度を、検査モード検出部１０５を介して過速度判定部１０７へ出力する。 The speed detection unit 101 outputs the detected speed of the car 1 to the overspeed determination unit 107 via the inspection mode detection unit 105.
　なお、検査モード検出部１０５は、速度検出部１０１および後述する模擬速度生成部１０２の各出力のいずれかを、過速度判定部１０７の入力に接続する。ロープレスガバナシステムの通常動作中、検査モード検出部１０５は、速度検出部１０１の出力を、過速度判定部１０７の入力に接続する。 Note that the inspection mode detection unit 105 connects any of the outputs of the speed detection unit 101 and the simulated speed generation unit 102 (described later) to the input of the overspeed determination unit 107. During normal operation of the ropeless governor system, the inspection mode detection section 105 connects the output of the speed detection section 101 to the input of the overspeed determination section 107.
　過速度判定部１０７は、速度検出部１０１から入力する検出速度が、第１過速度以上であるかを判定する。過速度判定部１０７は、検出速度が第１過速度以上であると判定すると、判定結果を駆動電源遮断指令部１０８へ送る。 The overspeed determining unit 107 determines whether the detected speed input from the speed detecting unit 101 is equal to or higher than the first overspeed. When the overspeed determination section 107 determines that the detected speed is equal to or higher than the first overspeed, the overspeed determination section 107 sends the determination result to the drive power cutoff command section 108 .
　駆動電源遮断指令部１０８は、過速度判定部１０７から判定結果を受けると、巻上機および制御装置６０の電源を遮断するための指令信号を出力する。 When the drive power cutoff command unit 108 receives the determination result from the overspeed determination unit 107, it outputs a command signal to shut off the power to the hoisting machine and the control device 60.
　また、過速度判定部１０７は、速度検出部１０１から入力する検出速度が、第２過速度以上であるかを判定する。過速度判定部１０７は、検出速度が第２過速度以上であると判定すると、判定結果を電磁石電源遮断指令部１０９へ送る。 Additionally, the overspeed determination unit 107 determines whether the detected speed input from the speed detection unit 101 is equal to or higher than the second overspeed. When the overspeed determination section 107 determines that the detected speed is equal to or higher than the second overspeed, the overspeed determination section 107 sends the determination result to the electromagnet power cutoff command section 109 .
　電磁石電源遮断指令部１０９は、過速度判定部１０７から判定結果を受けると、電動非常止め装置における電動操作器３（図１）の電磁石の電源を遮断するための指令信号を出力する。 Upon receiving the determination result from the overspeed determination unit 107, the electromagnet power cutoff command unit 109 outputs a command signal to shut off the power to the electromagnet of the electric actuator 3 (FIG. 1) in the electric emergency stop device.
　次に、ロープレスガバナシステムの検査時における動作について説明する。 Next, the operation during inspection of the ropeless governor system will be explained.
　保守用端末装置２００が、安全制御装置１００に、通信可能に接続される。なお、保守用端末装置２００は、パーソナルコンピュータなどによって構成される。 A maintenance terminal device 200 is communicably connected to the safety control device 100. Note that the maintenance terminal device 200 is configured by a personal computer or the like.
　保守用端末装置２００は、検査モード指令部２０１によって、安全制御装置１００に対して、通常動作モードから検査動作モードへの切り替えを指令する指令信号を送る。 The maintenance terminal device 200 uses the inspection mode command unit 201 to send a command signal to the safety control device 100 to instruct switching from the normal operation mode to the inspection operation mode.
　安全制御装置１００における検査モード切替部１０６は、保守用端末装置２００から指令信号を受けると、検査モード検出部１０５に対して、模擬速度生成部１０２の出力と過速度判定部１０７の入力との接続を指令する。検査モード検出部１０５は、検査モード切替部１０６の指令に応じて、速度検出部１０１の出力と過速度判定部１０７の入力との接続を解除し、模擬速度生成部１０２の出力と過速度判定部１０７の入力とを接続する。 When the inspection mode switching unit 106 in the safety control device 100 receives a command signal from the maintenance terminal device 200, the inspection mode switching unit 106 instructs the inspection mode detection unit 105 to output the output of the simulated speed generation unit 102 and the input of the overspeed determination unit 107. Command the connection. The inspection mode detection section 105 disconnects the output of the speed detection section 101 and the input of the overspeed determination section 107 in response to a command from the inspection mode switching section 106, and connects the output of the simulated speed generation section 102 with the overspeed determination section. It is connected to the input of section 107.
　模擬速度生成部１０２は、速度検出部１０１が出力する乗りかご１の検出速度に、比例器１０３によって定数を掛けることによって、検査用の模擬速度を生成する。 The simulated speed generation unit 102 generates a simulated speed for inspection by multiplying the detected speed of the car 1 output by the speed detection unit 101 by a constant using the proportional device 103.
　非接触センサ２が乗りかご１に設けられているため、速度検出部１０１が出力する検出速度は、主ロープの弾性による乗りかご１の振動に伴う振動成分を含む場合がある。模擬速度生成部１０２においては、この振動成分も定数倍される。そこで、本実施例においては、比例器１０３が出力する模擬速度の振動成分をローパスフィルタ１０４により除去する。模擬速度生成部１０２は、振動成分が除去された模擬速度を出力する。これにより、ロープレスガバナシステムの検査の信頼性が向上する。 Since the non-contact sensor 2 is provided in the car 1, the detected speed output by the speed detection unit 101 may include a vibration component due to the vibration of the car 1 due to the elasticity of the main rope. In the simulated velocity generating section 102, this vibration component is also multiplied by a constant. Therefore, in this embodiment, the vibration component of the simulated speed output by the proportional device 103 is removed by the low-pass filter 104. The simulated speed generation unit 102 outputs a simulated speed from which vibration components have been removed. This improves the reliability of testing the ropeless governor system.
　ロープレスガバナシステムの動作検査時には、乗りかご１は、定格速度以下の速度範囲で運転される。定数Ｋは、速度範囲内の所定速度をＫ倍した速度が上述の第２過速度に等しくなるように設定される（０＜所定速度≦定格速度、Ｋ×所定速度＝第２過速度）。これにより、乗りかご１を定格速度以下の速度で走行させながら、ロープレスガバナシステムの動作を検査することができる。 When testing the operation of the ropeless governor system, the car 1 is operated in a speed range below the rated speed. The constant K is set such that the speed obtained by multiplying the predetermined speed within the speed range by K is equal to the above-mentioned second overspeed (0<predetermined speed≦rated speed, K×predetermined speed=second overspeed). Thereby, the operation of the ropeless governor system can be inspected while the car 1 is running at a speed below the rated speed.
　ローパスフィルタ１０４の遮断周波数は、主ロープおよび乗りかご１からなる振動系の固有周波数に設定される。乗りかご１の位置によって、振動系を構成する主ロープの長さが異なるため、固有周波数は変動する。このため、好ましくは、遮断周波数は、最小の固有周波数に設定される。 The cutoff frequency of the low-pass filter 104 is set to the natural frequency of the vibration system consisting of the main rope and the car 1. Since the length of the main rope that constitutes the vibration system differs depending on the position of the car 1, the natural frequency varies. For this reason, the cutoff frequency is preferably set to the minimum natural frequency.
　模擬速度生成部１０２は、乗りかご１の模擬速度を、検査モード検出部１０５を介して過速度判定部１０７へ出力する。 The simulated speed generation unit 102 outputs the simulated speed of the car 1 to the overspeed determination unit 107 via the inspection mode detection unit 105.
　過速度判定部１０７は、模擬速度生成部１０２から入力する模擬速度が、第１過速度以上であるかを判定する。過速度判定部１０７は、模擬速度が第１過速度以上であると判定すると、判定結果および模擬速度の値を保守用端末装置２００へ送る。これにより、保守用端末装置２００は、乗りかご１の速度が第１過速度に達するとロープレスガバナシステムが所定の動作を行うこと、並びにその際の乗りかご１の速度を検出する。 The overspeed determining unit 107 determines whether the simulated speed input from the simulated speed generating unit 102 is greater than or equal to the first overspeed. When the overspeed determination unit 107 determines that the simulated speed is equal to or higher than the first overspeed, it sends the determination result and the value of the simulated speed to the maintenance terminal device 200 . Thereby, the maintenance terminal device 200 detects that the ropeless governor system performs a predetermined operation when the speed of the car 1 reaches the first overspeed, and detects the speed of the car 1 at that time.
　保守用端末装置２００は、液晶ディスプレイなどの表示装置を備える速度表示部２０２によって、過速度判定部１０７から受けた判定結果および模擬速度の値を表示する。 The maintenance terminal device 200 displays the determination result and the simulated speed value received from the overspeed determination section 107 using a speed display section 202 that includes a display device such as a liquid crystal display.
　さらに、過速度判定部１０７は、模擬速度生成部１０２から入力する模擬速度が、第２過速度以上であるかを判定する。過速度判定部１０７は、模擬速度が第２過速度以上であると判定すると、判定結果および模擬速度の値を保守用端末装置２００へ送る。これにより、保守用端末装置２００は、乗りかご１の速度が第２過速度に達するとロープレスガバナシステムが所定の動作を行うこと、並びにその際の乗りかご１の速度を検出する。この場合においても、保守用端末装置２００は、速度表示部２０２によって、過速度判定部１０７から受けた判定結果および模擬速度の値を表示する。 Further, the overspeed determining unit 107 determines whether the simulated speed input from the simulated speed generating unit 102 is equal to or higher than the second overspeed. When the overspeed determination unit 107 determines that the simulated speed is equal to or higher than the second overspeed, it sends the determination result and the value of the simulated speed to the maintenance terminal device 200 . Thereby, the maintenance terminal device 200 detects that the ropeless governor system performs a predetermined operation when the speed of the car 1 reaches the second overspeed, and detects the speed of the car 1 at that time. In this case as well, the maintenance terminal device 200 displays the determination result received from the overspeed determining section 107 and the value of the simulated speed using the speed display section 202.
　検査動作モードにおいて、過速度判定部１０７は、駆動電源遮断指令部１０８および電磁石電源遮断指令部１０９には判定結果を送らない。したがって、乗りかご１が非常停止されることはない。なお、駆動電源遮断指令部１０８および電磁石電源遮断指令部１０９において、判定結果が無効化されるようにしてもよい。 In the inspection operation mode, the overspeed determination section 107 does not send the determination result to the drive power cutoff command section 108 and the electromagnet power cutoff command section 109. Therefore, the car 1 will not be brought to an emergency stop. Note that the determination result may be invalidated in the drive power cutoff command section 108 and the electromagnet power cutoff command section 109.
　図３は、本実施例の安全制御装置１００の検査動作モードにおける処理動作を示すフローチャートである。 FIG. 3 is a flowchart showing processing operations in the inspection operation mode of the safety control device 100 of this embodiment.
　本実施例では、安全制御装置１００が設けられている乗りかご１上において、保守技術者が、保守用端末装置２００を用いて、ロープレスガバナシステムの動作の検査を実行する。このとき、エレベータ装置の運転モードは、保守運転モードに設定されている。保守運転モードおいて、保守技術者は、乗りかご１上に設けられる保守用操作盤を手動操作することにより、定格速度よりも低速で、乗りかご１を走行させる。 In this embodiment, a maintenance engineer inspects the operation of the ropeless governor system using the maintenance terminal device 200 on the car 1 in which the safety control device 100 is installed. At this time, the operation mode of the elevator system is set to maintenance operation mode. In the maintenance operation mode, a maintenance engineer manually operates a maintenance operation panel provided on the car 1 to cause the car 1 to travel at a speed lower than the rated speed.
　保守技術者は、保守用端末装置２００を、通信線を介して、安全制御装置１００に通信可能に接続する。次に、保守技術者は、保守用端末装置２００を操作して、安全制御装置１００の動作モードを、通常動作モードから検査動作モードへ切り替える。 A maintenance engineer communicably connects the maintenance terminal device 200 to the safety control device 100 via a communication line. Next, the maintenance engineer operates the maintenance terminal device 200 to switch the operation mode of the safety control device 100 from the normal operation mode to the inspection operation mode.
　安全制御装置１００が処理動作を開始すると、まず、ステップＳ１において、保守技術者が保守用操作盤を操作することにより、乗りかご１が走行を開始する。乗りかご１は、走行を開始すると、定格速度よりも低速の速度範囲で、加速走行する。 When the safety control device 100 starts the processing operation, first, in step S1, the maintenance engineer operates the maintenance operation panel, and the car 1 starts traveling. When the car 1 starts traveling, it accelerates in a speed range lower than the rated speed.
　ステップＳ２において、安全制御装置１００は、非接触センサ２からのセンサ信号を取得する。 In step S2, the safety control device 100 acquires a sensor signal from the non-contact sensor 2.
　次に、ステップＳ３において、安全制御装置１００は、速度検出部１０１を用いて、ステップＳ１で取得したセンサ信号に基づいて、乗りかご１の速度を検出する。 Next, in step S3, the safety control device 100 uses the speed detection unit 101 to detect the speed of the car 1 based on the sensor signal acquired in step S1.
　次に、ステップＳ４において、安全制御装置１００は、模擬速度生成部１０２における比例器１０３を用いて、ステップＳ３で得られた乗りかご１の検出速度を定数倍することによって、検査用の模擬速度を算出する。 Next, in step S4, the safety control device 100 uses the proportional device 103 in the simulated speed generation unit 102 to multiply the detected speed of the car 1 obtained in step S3 by a constant, thereby creating a simulated speed for inspection. Calculate.
　次に、ステップＳ５において、安全制御装置１００は、模擬速度生成部１０２におけるローパスフィルタ１０４を用いて、ステップＳ４で算出した模擬速度をフィルタリングする。 Next, in step S5, the safety control device 100 filters the simulated speed calculated in step S4 using the low-pass filter 104 in the simulated speed generating section 102.
　次に、ステップＳ６において、安全制御装置１００は、過速度判定部１０７を用いて、ステップＳ５でフィルタリングされた模擬速度が、第１過速度以上であるかを判定する。安全制御装置１００は、模擬速度が第１過速度以上ではないと判定すると（ステップＳ６のＮＯ）、ステップＳ２以降の処理を再度実行する。また、安全制御装置１００は、模擬速度が第１過速度以上であると判定すると（ステップＳ６のＹＥＳ）、次に、ステップＳ７を実行する。 Next, in step S6, the safety control device 100 uses the overspeed determination unit 107 to determine whether the simulated speed filtered in step S5 is equal to or higher than the first overspeed.
