Description

状態判定装置およびエレベータ制御装置Status judgment device and elevator control device
　本開示は、エレベータ制御盤の状態を判定する状態判定装置およびエレベータ制御装置に関するものである。 The present disclosure relates to a state determination device for determining the state of an elevator control panel and an elevator control device.
　エレベータ装置の定期的な保守作業、および地震等の後の点検作業の際、保守員がエレベータ制御盤の戸を開閉することがある。保守員がエレベータ制御盤の戸を閉じたとき、戸に配線等の異物が挟まることがあり、このままエレベータ装置を運行させると、地絡や短絡等に起因する事故が発生する可能性がある。そこで、こうした事故を未然に防止するため、エレベータ制御盤の異物の挟み込みを検出する技術が知られている（例えば、特許文献１参照）。 During regular maintenance work of the elevator equipment and inspection work after an earthquake etc., maintenance personnel may open and close the door of the elevator control panel. When a maintenance person closes the door of the elevator control panel, foreign matter such as wiring may get caught in the door, and if the elevator device is operated as it is, an accident due to a ground fault, a short circuit, or the like may occur. Therefore, in order to prevent such an accident, a technique for detecting the pinching of foreign matter in the elevator control panel is known (see, for example, Patent Document 1).
　特許文献１に開示されたエレベータ制御盤は、筐体本体の開口部に第１導体が配置され、戸の筐体側の面に第２導体が配置されている。第１導体と、第２導体とは、戸が筐体の開口部を塞ぐ閉状態で、戸に異物が挟まれていない状態であれば、どちらかの導体に通電させると、第１導体と第２導体とが導通する回路を形成するように配置されている。従って、第１導体と第２導体とが導通するか否かを確認することで、エレベータ制御盤の戸に異物が挟まれているか否かを検出することができる。 In the elevator control panel disclosed in Patent Document 1, the first conductor is arranged in the opening of the housing body, and the second conductor is arranged on the surface of the door on the housing side. If the door closes the opening of the housing and no foreign matter is caught in the door, the first conductor and the second conductor will be the first conductor when one of the conductors is energized. It is arranged so as to form a circuit in which the second conductor is conductive. Therefore, by confirming whether or not the first conductor and the second conductor are conductive, it is possible to detect whether or not a foreign substance is caught in the door of the elevator control panel.

　しかし、特許文献１に開示されたエレベータ制御盤は、戸に異物が挟まれていることは判定できるが、それ以外の異常状態については判定することができない。本開示は、上記のような問題を解決するためになされたものであり、エレベータ制御盤がとりうる異物の挟み込み以外の異常状態も判定することができる状態判定装置およびエレベータ制御装置を提供することを目的とする。 However, the elevator control panel disclosed in Patent Document 1 can determine that a foreign substance is caught in the door, but cannot determine other abnormal states. The present disclosure has been made to solve the above-mentioned problems, and provides a state determination device and an elevator control device capable of determining an abnormal state other than the pinching of foreign matter that can be taken by the elevator control panel. With the goal.
　本開示の状態判定装置は、筐体と筐体に開閉可能に取り付けられた戸とを備えるエレベータ制御盤の状態を判定する状態判定装置であって、戸、または戸との間の異物までの距離を検出する複数の距離検出部から、それぞれ検出値を取得する距離情報取得部と、距離情報取得部が取得した検出値を記憶する距離情報記憶部と、距離検出部が検出する検出値と、戸が正常に閉じられた状態における距離検出部から戸までの距離の正常値との大小関係に対応するエレベータ制御盤の状態を示す状態判定情報を記憶する判定情報記憶部と、距離情報記憶部が記憶する検出値と正常値との大小関係を求め、状態判定情報を用いて、求めた大小関係に対応するエレベータ制御盤の状態を特定する状態特定部と、を備える。 The state determination device of the present disclosure is a state determination device that determines the state of an elevator control panel including a housing and a door that is openably and closably attached to the housing, and is a state determination device that determines the state of the door or a foreign object between the doors. A distance information acquisition unit that acquires detection values from a plurality of distance detection units that detect a distance, a distance information storage unit that stores the detection values acquired by the distance information acquisition unit, and a detection value detected by the distance detection unit. , Judgment information storage unit that stores the state judgment information indicating the state of the elevator control panel corresponding to the magnitude relationship with the normal value of the distance from the distance detection unit to the door when the door is normally closed, and the distance information storage unit. It is provided with a state specifying unit that obtains the magnitude relationship between the detected value and the normal value stored in the unit and specifies the state of the elevator control panel corresponding to the determined magnitude relationship by using the state determination information.
　本開示の状態判定装置およびエレベータ制御装置は、距離情報記憶部が記憶する検出値と正常値との大小関係を求め、状態判定情報を用いて、求めた大小関係に対応するエレベータ制御盤の状態を特定する状態特定部を備えるので、大小関係に対応するエレベータ制御盤がとりうる異物の挟み込み以外の異常状態を予め状態判定情報に記憶させておくことで、異物の挟み込み以外の異常状態についても判定することができる。 The state determination device and the elevator control device of the present disclosure obtain the magnitude relationship between the detected value and the normal value stored in the distance information storage unit, and use the state determination information to obtain the state of the elevator control panel corresponding to the determined magnitude relationship. Since it is equipped with a state identification unit that specifies the state, by storing in advance the abnormal state other than the pinching of foreign matter that can be taken by the elevator control panel corresponding to the magnitude relationship in the state judgment information, it is possible to handle the abnormal state other than the pinching of foreign matter.

When a foreign matter 9 such as wiring is present between the distance detection unit 22 and the door 21, the distance detection unit 22 detects the distance to the foreign matter 9 between the door 21 and the foreign matter 9.
　エレベータ制御装置２００は、巻上機７の駆動制御のようにエレベータ装置１が備える装置の制御と、エレベータ制御盤２の状態判定等の演算処理を行う。エレベータ制御装置２００は、状態判定装置２４を備え、状態判定装置２４でエレベータ制御盤２の状態を判定する。 The elevator control device 200 controls the device included in the elevator device 1 like the drive control of the hoisting machine 7, and performs arithmetic processing such as determining the state of the elevator control panel 2.

　続いて、実施の形態１のエレベータ制御盤２の詳細について説明する。図３は、本開示の実施の形態１のエレベータ制御盤２の機能ブロック図である。 Subsequently, the details of the elevator control panel 2 of the first embodiment will be described. FIG. 3 is a functional block diagram of the elevator control panel 2 of the first embodiment of the present disclosure.
　図３には図１、２では示していない表示部１０を示しているが、これは保守員にエレベータ制御盤２の状態を示すモニター、または保守員が携帯する保守用端末等である。表示部１０は、保守員にエレベータ制御盤２の状態を表示する。表示態様は例えばエレベータ制御盤２の状態を示す文字または図、もしくは音声等でよい。表示部１０を設置する位置はどこでもよいが、保守員がエレベータ制御盤２の戸２１を開けなくともエレベータ制御盤２の状態を知ることができる位置に表示部１０を設置することが望ましい。または、ネットワーク経由でエレベータ制御盤２の状態を取得可能な保守員の保守用端末等を表示部１０とし、移動可能に設けてもよい。 FIG. 3 shows a display unit 10 which is not shown in FIGS. 1 and 2, but this is a monitor showing the state of the elevator control panel 2 to the maintenance staff, a maintenance terminal carried by the maintenance staff, or the like. The display unit 10 displays the status of the elevator control panel 2 to the maintenance staff. The display mode may be, for example, characters or figures indicating the state of the elevator control panel 2, voice, or the like. The display unit 10 may be installed at any position, but it is desirable to install the display unit 10 at a position where the maintenance personnel can know the state of the elevator control panel 2 without opening the door 21 of the elevator control panel 2. Alternatively, a maintenance terminal or the like of a maintenance worker who can acquire the state of the elevator control panel 2 via the network may be used as the display unit 10 and may be provided so as to be movable.
　エレベータ制御装置２００は、情報を取得する取得部２１０、情報を記憶する記憶部２２０、プログラムの実行および演算を行う処理部２３０、エレベータ装置１が備える各装置を制御する制御部２４０、保守員が操作する操作部２５０を備える。エレベータ制御装置２００はそれ以外の構成を備えてもよい。以下、各部の詳細を説明するが、エレベータ制御装置２００はこれらの構成を以下で説明する用途以外に用いてもよい。 The elevator control device 200 includes an acquisition unit 210 for acquiring information, a storage unit 220 for storing information, a processing unit 230 for executing and calculating programs, a control unit 240 for controlling each device included in the elevator device 1, and maintenance personnel. The operation unit 250 to be operated is provided. The elevator control device 200 may have other configurations. The details of each part will be described below, but the elevator control device 200 may use these configurations for purposes other than those described below.
　取得部２１０は、距離検出部２２ａ、２２ｂが検出した距離を取得する距離情報取得部２１１と、保守員が操作部２５０で行った操作の情報を取得する操作情報取得部２１２とを備える。 The acquisition unit 210 includes a distance information acquisition unit 211 that acquires the distance detected by the distance detection units 22a and 22b, and an operation information acquisition unit 212 that acquires information on the operation performed by the maintenance staff on the operation unit 250.
　距離情報取得部２１１は、距離検出部２２と有線または無線で通信を行い、複数の距離検出部２２からそれぞれ検出値を取得する。つまり、実施の形態１の距離情報取得部２１１は、距離検出部２２ａ、２２ｂからそれぞれ検出値を取得する。なお、距離情報取得部２１１は、検出値とともに距離検出部２２ａ、２２ｂから識別情報を取得する、または検出値を取得した距離情報取得部２１１が備える入力インターフェースの識別情報と対応づけることで、取得した検出値が距離検出部２２ａ、２２ｂのどちらのものであるかを識別する。 The distance information acquisition unit 211 communicates with the distance detection unit 22 by wire or wirelessly, and acquires detection values from each of the plurality of distance detection units 22. That is, the distance information acquisition unit 211 of the first embodiment acquires detection values from the distance detection units 22a and 22b, respectively. The distance information acquisition unit 211 acquires identification information from the distance detection units 22a and 22b together with the detection value, or acquires the detection value by associating it with the identification information of the input interface included in the distance information acquisition unit 211 that has acquired the detection value. It is identified which of the distance detection units 22a and 22b the detected value is.
　操作情報取得部２１２は、操作部２５０から操作情報を取得する。保守員は操作部２５０で保守モードと通常モードを切り替える操作を行う。操作部２５０は例えば、スイッチ、レバー、ボタン等がこれに相当する。 The operation information acquisition unit 212 acquires operation information from the operation unit 250. The maintenance staff operates the operation unit 250 to switch between the maintenance mode and the normal mode. The operation unit 250 corresponds to, for example, a switch, a lever, a button, or the like.
　記憶部２２０は、取得部２１０と処理部２３０と接続され、取得部２１０が取得した情報等必要な情報を記憶する。記憶部２２０は具体的には、情報を記憶することができるＨＤＤやＳＤカード等の記憶媒体である。記憶部２２０は距離情報記憶部２２１、判定情報記憶部２２２、および操作情報記憶部２２３を備える。 The storage unit 220 is connected to the acquisition unit 210 and the processing unit 230, and stores necessary information such as the information acquired by the acquisition unit 210. Specifically, the storage unit 220 is a storage medium such as an HDD or an SD card that can store information. The storage unit 220 includes a distance information storage unit 221, a determination information storage unit 222, and an operation information storage unit 223.
　距離情報記憶部２２１は、距離情報取得部２１１が取得した距離検出部２２ａ、２２ｂの検出値を記憶する。 The distance information storage unit 221 stores the detection values of the distance detection units 22a and 22b acquired by the distance information acquisition unit 211.
　判定情報記憶部２２２は、エレベータ制御盤２の状態の判定に必要な状態判定情報を記憶する。具体的には、状態判定情報は距離検出部２２が検出する検出値と、戸２１が正常に閉じられた状態における距離検出部２２から戸２１までの距離の正常値との大小関係に対応するエレベータ制御盤２の状態を示す情報である。状態判定情報は、判定情報記憶部２２２に製造段階または据付段階に予め記憶させておく。ただし、状態判定情報は判定情報記憶部２２２に記憶させた後、保守員が状態判定情報の正常値および大小関係に対応するエレベータ制御盤２の状態を変更してもよい。 The determination information storage unit 222 stores the state determination information necessary for determining the state of the elevator control panel 2. Specifically, the state determination information corresponds to the magnitude relationship between the detection value detected by the distance detection unit 22 and the normal value of the distance from the distance detection unit 22 to the door 21 when the door 21 is normally closed. This is information indicating the state of the elevator control panel 2. The state determination information is stored in advance in the determination information storage unit 222 at the manufacturing stage or the installation stage. However, after the state determination information is stored in the determination information storage unit 222, the maintenance staff may change the state of the elevator control panel 2 corresponding to the normal value and the magnitude relationship of the state determination information.
　ここで、実施の形態１の判定情報記憶部２２２が記憶する状態判定情報について説明する。図４は、本開示の実施の形態１の状態判定情報を示す説明図である。図４で示す状態判定情報は、一例であり、図４には含まれていないが蝶番２３のネジの緩み等で起きる戸２１の傾きやズレなどの状態も状態判定情報に加えてもよい。図４では距離検出部２２が検出する距離の検出値と正常値との大小関係に対応するエレベータ制御盤２の状態は１つのみ示されているが、発生する可能性のある状態が複数ある場合、複数の状態を全て示してもよい。 Here, the state determination information stored in the determination information storage unit 222 of the first embodiment will be described. FIG. 4 is an explanatory diagram showing the state determination information of the first embodiment of the present disclosure. The state determination information shown in FIG. 4 is an example, and although not included in FIG. 4, a state such as inclination or misalignment of the door 21 caused by loosening of the hinge 23 screw may be added to the state determination information. In FIG. 4, only one state of the elevator control panel 2 corresponding to the magnitude relationship between the detected value of the distance detected by the distance detecting unit 22 and the normal value is shown, but there are a plurality of states that may occur. In the case, a plurality of states may be indicated at all.
　実施の形態１の状態判定情報は、距離検出部２２ａの検出値Ｄａ２と正常値Ｄａ１との大小関係、および距離検出部２２ｂの検出値Ｄｂ２と正常値Ｄｂ１との大小関係に対応する予測されるエレベータ制御盤２の状態を示す。 The state determination information of the first embodiment corresponds to the magnitude relationship between the detection value D a2 of the distance detection unit 22a and the normal value D a1, and the magnitude relationship between the detection value D b2 of the distance detection unit 22b and the normal value D b1. The predicted state of the elevator control panel 2 is shown.
　Ｄａ１は、エレベータ制御盤２の戸２１が正常に閉じられた状態での、距離検出部２２ａから戸２１までの距離の正常値である。Ｄｂ１は距離検出部２２ｂから戸２１までの距離の正常値である。Ｄａ１とＤｂ１は予めエレベータ装置１の導入時やエレベータ制御盤２の製造時等にエレベータ制御盤２の戸２１が正常に閉じられた状態で、距離検出部２２ａ、２２ｂを用いて実際に検出した値を用いても、距離検出部２２ａ、２２ｂを用いずに実際にスケールを用いて距離を測定することで求めてもよい。なお、実施の形態１では距離検出部２２ａ、２２ｂの正常値Ｄａ１、Ｄｂ１をそれぞれ定めたが、距離検出部２２の設置場所およびエレベータ制御盤２の形状次第で、正常値を１つの同じ値として定めてもよい。 D a1 is a normal value of the distance from the distance detection unit 22a to the door 21 when the door 21 of the elevator control panel 2 is normally closed. D b1 is a normal value of the distance from the distance detection unit 22b to the door 21. D a1 and D b1 are actually mounted using the distance detection units 22a and 22b in a state where the door 21 of the elevator control panel 2 is normally closed when the elevator device 1 is introduced or when the elevator control panel 2 is manufactured. The detected value may be used, or the distance may be obtained by actually measuring the distance using a scale without using the distance detection units 22a and 22b. In the first embodiment, the normal values D a1 and D b1 of the distance detection units 22a and 22b are determined, respectively, but the normal values are the same depending on the installation location of the distance detection unit 22 and the shape of the elevator control panel 2. It may be set as a value.
　Ｄａ２は、エレベータ制御盤２の状態を判定する際に距離検出部２２ａが検出する検出値である。Ｄｂ２は、エレベータ制御盤２の状態を判定する際に距離検出部２２ｂが検出する検出値である。 D a2 is a detection value detected by the distance detection unit 22a when determining the state of the elevator control panel 2. D b2 is a detection value detected by the distance detection unit 22b when determining the state of the elevator control panel 2.
　図４で示す状態判定情報に含まれるエレベータ制御盤２の状態に応じた、距離の検出値と正常値について説明する。 The distance detection value and the normal value according to the state of the elevator control panel 2 included in the state determination information shown in FIG. 4 will be described.
　まず、戸２１が正常に閉じられた状態における距離の検出値と正常値について説明する。図５は、戸２１が正常に閉じられた状態のエレベータ制御盤２の上面図である。図５において、距離検出部２２ａと距離検出部２２ｂは戸２１との距離をそれぞれ開口部の異なる位置で検出する。図５のように戸２１が正常に閉じられた状態であるときの距離検出部２２ａと戸２１との距離がＤａ１、距離検出部２２ｂと戸２１との距離がＤｂ１である。図５は、戸２１が正常に閉じられた状態を示しているので、距離検出部２２ａの検出値Ｄａ２と正常値Ｄａ１、および距離検出部２２ｂの検出値Ｄｂ２と正常値Ｄｂ１は、同じ距離となっている。従って、状態判定情報では距離検出部２２ａの検出値Ｄａ２と正常値Ｄａ１、および距離検出部２２ｂの検出値Ｄｂ２と正常値Ｄｂ１とが同じ場合、対応するエレベータ制御盤２の状態は正常な状態であることを示している。 First, the detected value and the normal value of the distance when the door 21 is normally closed will be described. FIG. 5 is a top view of the elevator control panel 2 in a state where the door 21 is normally closed. In FIG. 5, the distance detection unit 22a and the distance detection unit 22b detect the distance between the door 21 and the door 21 at different positions of the openings. As shown in FIG. 5, the distance between the distance detection unit 22a and the door 21 when the door 21 is normally closed is Da1 , and the distance between the distance detection unit 22b and the door 21 is Db1 . FIG. 5 shows a state in which the door 21 is normally closed. Therefore, the detection values D a2 and the normal value D a1 of the distance detection unit 22a, and the detection values D b2 and the normal value D b1 of the distance detection unit 22b are shown. , It is the same distance. Therefore, in the state determination information, when the detection value D a2 and the normal value D a1 of the distance detection unit 22a and the detection value D b2 and the normal value D b1 of the distance detection unit 22b are the same, the state of the corresponding elevator control panel 2 is It indicates that it is in a normal state.
　続いて、戸２１が一部ゆがんだ状態における距離の検出値と正常値について説明する。図６は戸２１が一部ゆがんだ状態のエレベータ制御盤２の上面図である。図６では距離検出部２２ｂが距離を検出する位置で、戸２１が外側に変位している。従って、距離検出部２２ｂが検出する検出値Ｄｂ２は正常値Ｄｂ１よりも大きい。距離検出部２２ａが距離を検出する位置では戸２１はゆがんでいないため、距離検出部２２ａが検出する検出値Ｄａ２は正常値Ｄａ１と同じ距離となっている。なお、戸２１が一部ゆがんだ状態は、図６で示す状態の他に、距離検出部２２ａが距離を検出する位置で、戸２１が外側に変位している場合もある。このとき距離検出部２２ａが検出する検出値Ｄａ２は正常値Ｄａ１よりも大きく、距離検出部２２ｂが検出する検出値Ｄｂ２は正常値Ｄｂ１と同じ距離となる。従って、検出値Ｄａ２、Ｄｂ２の少なくとも１つが正常値Ｄａ１、Ｄｂ１より大きく、その他の検出値Ｄａ２、Ｄｂ２が正常値Ｄａ１、Ｄｂ１と同じ場合、エレベータ制御盤２の状態は戸２１がゆがんだ状態である。従って、距離検出部２２ａの検出値Ｄａ２が正常値Ｄａ１よりも大きく、距離検出部２２ｂの検出値Ｄｂ２が正常値Ｄｂ１と同じ場合、又は距離検出部２２ｂの検出値Ｄｂ２が正常値Ｄｂ１よりも大きく、距離検出部２２ａの検出値Ｄａ２が正常値Ｄａ１と同じ場合は、状態判定情報においてエレベータ制御盤２の状態は、戸２１がゆがんだ状態であることを示している。 Subsequently, the detected value and the normal value of the distance in the state where the door 21 is partially distorted will be described. FIG. 6 is a top view of the elevator control panel 2 in a state where the door 21 is partially distorted. In FIG. 6, the door 21 is displaced outward at the position where the distance detection unit 22b detects the distance. Therefore, the detection value D b2 detected by the distance detection unit 22 b is larger than the normal value D b1. Since the door 21 is not distorted at the position where the distance detection unit 22a detects the distance, the detection value D a2 detected by the distance detection unit 22a is the same distance as the normal value D a1. In addition to the state shown in FIG. 6, when the door 21 is partially distorted, the door 21 may be displaced outward at a position where the distance detecting unit 22a detects the distance. At this time, the detection value D a2 detected by the distance detection unit 22a is larger than the normal value D a1 , and the detection value D b2 detected by the distance detection unit 22 b is the same distance as the normal value D b1. Accordingly, at least one greater than the normal value D a1, D b1 detection value D a2, D b2, if the same with other detection values D a2, D b2 normal value D a1, D b1, state of the elevator control panel 2 Is a distorted state of the door 21. Therefore, when the detection value D a2 of the distance detection unit 22a is larger than the normal value D a1 and the detection value D b2 of the distance detection unit 22b is the same as the normal value D b1 , or the detection value D b2 of the distance detection unit 22b is normal. When the value D a2 is larger than the value D b1 and the detection value D a2 of the distance detection unit 22a is the same as the normal value D a1 , the state of the elevator control panel 2 in the state determination information indicates that the door 21 is in a distorted state. There is.
　続いて、戸２１に異物９が挟まれたまま戸閉した状態における距離の検出値と正常値について説明する。なお、以下では戸２１に異物９が挟まれた状態を戸挟みが生じた状態と呼ぶ。図７は戸挟みが生じた状態のエレベータ制御盤２の上面図である。距離検出部２２ａが距離を検出する戸２１の位置で、戸２１の手前に挟まれた異物９が位置しているため、正常値Ｄａ１よりも検出値Ｄａ２の方が小さい。距離検出部２２ｂが検出する距離を検出する位置では異物９が挟まれていないため、距離検出部２２ｂが検出する検出値Ｄｂ２は正常値Ｄｂ１と同じ距離となっている。なお、図７で示す状態の他に、距離検出部２２ｂが距離を検出する位置で異物９が挟まれる、または距離検出部２２ａ、２２ｂが距離を検出する両方の位置で異物９が挟まれることもある。従って、検出値Ｄａ２、Ｄｂ２の少なくとも１つが正常値Ｄａ１、Ｄｂ１より小さく、その他の検出値Ｄａ２、Ｄｂ２が正常値Ｄａ１、Ｄｂ１以下である場合、戸挟みが生じている可能性がある。従って、検出値Ｄａ２が正常値Ｄａ１より小さく、かつ検出値Ｄｂ２が正常値Ｄｂ１以下である場合、又は検出値Ｄｂ２が正常値Ｄｂ１より小さく、かつ検出値Ｄａ２が正常値Ｄａ１以下である場合、状態判定情報において、エレベータ制御盤２の状態は戸挟み状態であることを示している。 Subsequently, the detected value and the normal value of the distance in the state where the door is closed with the foreign matter 9 sandwiched between the doors 21 will be described. In the following, the state in which the foreign matter 9 is sandwiched between the doors 21 is referred to as a state in which the doors are pinched. FIG. 7 is a top view of the elevator control panel 2 in a state where the door is pinched. Since the foreign matter 9 sandwiched in front of the door 21 is located at the position of the door 21 where the distance detecting unit 22a detects the distance, the detected value D a2 is smaller than the normal value D a1. Since the foreign matter 9 is not sandwiched at the position where the distance detected by the distance detecting unit 22b is detected, the detection value D b2 detected by the distance detecting unit 22b is the same distance as the normal value D b1. In addition to the state shown in FIG. 7, the foreign matter 9 is sandwiched at the position where the distance detection unit 22b detects the distance, or the foreign matter 9 is sandwiched at both positions where the distance detection units 22a and 22b detect the distance. There is also. Accordingly, at least one detection value D a2, D b2 but smaller than the normal value D a1, D b1, if other detectable value D a2, D b2 is equal to or less than the normal value D a1, D b1, occurs is Tohasami There may be. Therefore, when the detected value D a2 is smaller than the normal value D a1 and the detected value D b2 is equal to or less than the normal value D b1 , or the detected value D b2 is smaller than the normal value D b1 and the detected value D a 2 is the normal value. When it is D a1 or less, the state determination information indicates that the state of the elevator control panel 2 is a door-clamped state.
　続いて、戸２１が戸開した状態における距離の検出値と正常値について説明する。図８は戸開状態のエレベータ制御盤２の上面図である。戸開した状態では、距離検出部２２ａ、２２ｂが距離を検出する戸２１の位置両方で、戸２１が外側に変位する。従って、距離検出部２２ａが検出する検出値Ｄａ２は正常値Ｄａ１よりも大きく、距離検出部２２ｂが検出する検出値Ｄｂ２も正常値Ｄｂ１よりも大きい。従って、全ての検出値Ｄａ２、Ｄｂ２が正常値Ｄａ１、Ｄｂ１よりも大きい場合、戸開している可能性がある。従って、距離検出部２２ａ、２２ｂの検出値Ｄａ２、Ｄｂ２が正常値Ｄａ１、Ｄｂ１より大きい場合、状態判定情報において、エレベータ制御盤２の状態は戸開状態であると示す。 Subsequently, the detected value and the normal value of the distance when the door 21 is opened will be described. FIG. 8 is a top view of the elevator control panel 2 in the door open state. In the open state, the door 21 is displaced outward at both the positions of the door 21 where the distance detection units 22a and 22b detect the distance. Therefore, the detection value D a2 detected by the distance detection unit 22a is larger than the normal value D a1 , and the detection value D b2 detected by the distance detection unit 22 b is also larger than the normal value D b1. Therefore, if all the detected values D a2 and D b2 are larger than the normal values D a1 and D b1 , there is a possibility that the door is open. Therefore, when the detected values D a2 and D b2 of the distance detection units 22a and 22b are larger than the normal values D a1 and D b1 , the state of the elevator control panel 2 indicates that the door is open.
　なお、図示しないが検出値Ｄａ２、Ｄｂ２の少なくとも１つが正常値Ｄａ１、Ｄｂ１より小さく、検出値Ｄａ２、Ｄｂ２の少なくとも１つが正常値Ｄａ１、Ｄｂ１より大きい場合、戸が大きくゆがんでいる可能性もあるが、センサ不良である可能性が高い。センサ不良とは距離検出部２２ａ、２２ｂに異常が発生している状態であり、例えば、距離検出部２２ａ、２２ｂの設置位置または設置角度が正常な状態から変更された場合、または距離検出部２２ａ、２２ｂが故障し正しい距離を検出できなくなった場合等がある。従って、距離検出部２２ａ、２２ｂの距離の検出値Ｄａ２、Ｄｂ２の一方が正常値Ｄａ１、Ｄｂ１より大きく、距離検出部２２ａ、２２ｂの距離の検出値Ｄａ２、Ｄｂ２の他方が正常値Ｄａ１、Ｄｂ１より小さい場合、状態判定情報において、エレベータ制御盤２の状態はセンサ不良であることを示している。 Incidentally, not shown at least one of the detection value D a2, D b2 but smaller than the normal value D a1, D b1, if at least one of greater than normal value D a1, D b1 detection value D a2, D b2, door is It may be significantly distorted, but it is likely that the sensor is defective. A sensor failure is a state in which an abnormality has occurred in the distance detection units 22a and 22b. For example, when the installation position or installation angle of the distance detection units 22a and 22b is changed from the normal state, or the distance detection unit 22a , 22b may break down and the correct distance cannot be detected. Therefore, the distance detection unit 22a, one is larger than the normal value D a1, D b1 detection value D a2, D b2 of 22b distances, the distance detection unit 22a, the other detected value D a2, D b2 of 22b Distance When it is smaller than the normal values D a1 and D b1 , the state determination information indicates that the state of the elevator control panel 2 is a sensor failure.
　以上のように、実施の形態１の状態判定情報は、距離検出部２２ａ、２２ｂが検出するそれぞれの検出値Ｄａ２、Ｄｂ２について、正常値Ｄａ１、Ｄｂ１と比較して、正常値よりも小さい場合、正常値と同じ場合、および正常値よりも大きい場合の大小関係に対応するエレベータ制御盤２の状態を示す。従来の特許文献１では第１導体と第２導体とが導通するか否かを確認することで異物９の挟み込みの有無を検出していたが、本開示の状態判定装置２４は距離の検出値を用いてエレベータ制御盤２の状態を判定するため、正常値と比較して正常値よりも小さい場合、正常値と同じ場合、正常値よりも大きい場合のように、検出値に応じてエレベータ制御盤２の状態を記憶させることができる。なお、状態判定情報には正常値以外の所定の数値と比較した大小関係に対応付けてエレベータ制御盤２の状態を記憶させてもよい。 As described above, the state determination information of the first embodiment is based on the normal values of the detected values D a2 and D b2 detected by the distance detection units 22a and 22b, as compared with the normal values D a1 and D b1. Indicates the state of the elevator control panel 2 corresponding to the magnitude relationship when the value is small, the value is the same as the normal value, and the value is larger than the normal value. In the conventional patent document 1, the presence or absence of the foreign matter 9 being pinched is detected by confirming whether or not the first conductor and the second conductor are conductive, but the state determination device 24 of the present disclosure is a distance detection value. Since the state of the elevator control panel 2 is determined using the above, elevator control is performed according to the detected value, such as when it is smaller than the normal value, when it is the same as the normal value, or when it is larger than the normal value. The state of the board 2 can be memorized. The state of the elevator control panel 2 may be stored in the state determination information in association with a magnitude relationship compared with a predetermined value other than the normal value.
　操作情報記憶部２２３は、操作情報取得部２１２が取得した操作部２５０への操作情報を記憶する。 The operation information storage unit 223 stores the operation information acquired by the operation information acquisition unit 212 to the operation unit 250.
　続いて、処理部２３０について説明する。処理部２３０は、取得部２１０と記憶部２２０から取得した情報を用いて、エレベータ制御盤２の状態判定に必要な演算等を行う。処理部２３０は状態特定部２３１と、制御処理部２３２とを備える。 Next, the processing unit 230 will be described. The processing unit 230 uses the information acquired from the acquisition unit 210 and the storage unit 220 to perform calculations and the like necessary for determining the state of the elevator control panel 2. The processing unit 230 includes a state specifying unit 231 and a control processing unit 232.
　状態特定部２３１は、距離情報記憶部２２１が記憶する距離の検出値と、判定情報記憶部２２２が記憶する状態判定情報とを用いて、エレベータ制御盤２の状態の特定を行う。状態判定情報に大小関係に対応するエレベータ制御盤２がとりうる異物９の挟み込み以外の異常状態も含めて判定情報記憶部２２２に記憶させておくことで、状態特定部２３１は異物９の挟み込み以外の異常状態を特定することができる。 The state specifying unit 231 identifies the state of the elevator control panel 2 by using the distance detection value stored in the distance information storage unit 221 and the state determination information stored in the determination information storage unit 222. By storing in the judgment information storage unit 222 including abnormal states other than the pinching of the foreign matter 9 that can be taken by the elevator control panel 2 corresponding to the magnitude relation in the state judgment information, the state specifying unit 231 is other than the pinching of the foreign matter 9. It is possible to identify the abnormal state of.
　実施の形態１の状態特定部２３１は、距離情報記憶部２２１が記憶する距離の検出値を用いて、状態判定情報に記憶された距離の正常値との大小関係から、図４にて示したようにエレベータ制御盤２の状態を、正常な状態、戸挟み状態、センサ不良状態、戸２１にゆがみが生じた状態、戸開状態のいずれかであると特定する。なお、正常な状態以外は異常状態である。 The state specifying unit 231 of the first embodiment is shown in FIG. 4 from the magnitude relationship with the normal value of the distance stored in the state determination information using the detected value of the distance stored in the distance information storage unit 221. As described above, the state of the elevator control panel 2 is specified as one of a normal state, a door pinching state, a sensor failure state, a state in which the door 21 is distorted, and a door open state. It should be noted that other than the normal state, it is an abnormal state.
　制御処理部２３２は、エレベータ装置１の巻上機７およびエレベータ制御装置２００の表示部１０等の装置をどのように制御するか決定し、制御情報を制御部２４０に出力する。制御処理部２３２は操作情報記憶部２２３から取得する操作情報と、状態特定部２３１から取得するエレベータ制御盤２の状態の判定結果とを用いて、制御を決定する。例えば、操作情報記憶部２２３から保守モードから通常モードへの切替操作がなされたという操作情報を取得しても、状態特定部２３１がエレベータ制御盤２の状態が異常であると特定すると、保守モードのままで運転するよう制御部２４０に対して制御情報を出力する。 The control processing unit 232 determines how to control devices such as the hoisting machine 7 of the elevator device 1 and the display unit 10 of the elevator control device 200, and outputs control information to the control unit 240. The control processing unit 232 determines the control by using the operation information acquired from the operation information storage unit 223 and the state determination result of the elevator control panel 2 acquired from the state specifying unit 231. For example, even if the operation information storage unit 223 acquires the operation information that the operation for switching from the maintenance mode to the normal mode has been performed, if the state specifying unit 231 identifies that the state of the elevator control panel 2 is abnormal, the maintenance mode is used. The control information is output to the control unit 240 so that the operation can be performed as it is.
　制御部２４０は、制御処理部２３２から取得した制御情報に従って制御する対象の装置に制御信号を出力する。制御部２４０は、表示部１０を制御する表示制御部２４１と、巻上機７を制御する巻上機制御部２４２とを備える。 The control unit 240 outputs a control signal to the target device to be controlled according to the control information acquired from the control processing unit 232. The control unit 240 includes a display control unit 241 that controls the display unit 10 and a hoisting machine control unit 242 that controls the hoisting machine 7.
　表示制御部２４１は、制御処理部２３２から制御情報を取得し、表示部１０を制御する。表示制御部２４１は、表示部１０に状態特定部２３１が特定したエレベータ制御盤２の状態を示す情報を表示させる。 The display control unit 241 acquires control information from the control processing unit 232 and controls the display unit 10. The display control unit 241 causes the display unit 10 to display information indicating the state of the elevator control panel 2 specified by the state specifying unit 231.
　巻上機制御部２４２は、制御処理部２３２から取得する制御情報に基づき、巻上機７を制御する。 The hoisting machine control unit 242 controls the hoisting machine 7 based on the control information acquired from the control processing unit 232.
　図３では、実施の形態１の状態判定装置２４をエレベータ制御装置２００の一部として示したが、状態特定部２３１が制御処理部２３２に状態の判定結果を出力することができれば、状態判定装置２４をエレベータ制御装置２００の外部の装置に設けてもよい。状態判定装置２４をエレベータ制御装置２００と別体とすることで、既存のエレベータ制御装置２００を交換することなく、本開示の状態判定装置２４によりエレベータ制御盤２の状態を判定することができる。 In FIG. 3, the state determination device 24 of the first embodiment is shown as a part of the elevator control device 200, but if the state identification unit 231 can output the state determination result to the control processing unit 232, the state determination device 24 may be provided in a device outside the elevator control device 200. By separating the state determination device 24 from the elevator control device 200, the state of the elevator control panel 2 can be determined by the state determination device 24 of the present disclosure without replacing the existing elevator control device 200.
　次に、本開示の実施の形態１のエレベータ制御装置２００の動作について、図９を用いて説明する。図９は本開示の実施の形態１におけるエレベータ制御装置２００の動作を示すフローチャートである。 Next, the operation of the elevator control device 200 according to the first embodiment of the present disclosure will be described with reference to FIG. FIG. 9 is a flowchart showing the operation of the elevator control device 200 according to the first embodiment of the present disclosure.
　エレベータ装置１の電源を入れると、まず、エレベータ制御装置２００はステップＳ１を実行し、エレベータ装置１が保守モードでの稼働を開始する。その後、ステップＳ２において、制御処理部２３２が通常モードへの切替操作が行われたか否かを、操作情報記憶部２２３に記憶された操作情報に基づいて判断する。エレベータ制御装置２００は、通常モードの切替操作が行われていないと判断するとステップＳ１に戻り、通常モードへの切替操作が行われるまで保守モードでの稼働を継続する。エレベータ制御装置２００は、通常モードへの切替操作が行われたと判断するとステップＳ３を実行する。 When the power of the elevator device 1 is turned on, the elevator control device 200 first executes step S1, and the elevator device 1 starts operation in the maintenance mode. After that, in step S2, the control processing unit 232 determines whether or not the switching operation to the normal mode has been performed based on the operation information stored in the operation information storage unit 223. When it is determined that the normal mode switching operation has not been performed, the elevator control device 200 returns to step S1 and continues to operate in the maintenance mode until the normal mode switching operation is performed. When the elevator control device 200 determines that the operation for switching to the normal mode has been performed, the elevator control device 200 executes step S3.
　ステップＳ３では、距離情報取得部２１１が距離検出部２２ａ、２２ｂから検出値を取得し、距離情報取得部２１１が取得した検出値を距離情報記憶部２２１が記憶する。 In step S3, the distance information acquisition unit 211 acquires the detected values from the distance detection units 22a and 22b, and the distance information storage unit 221 stores the detected values acquired by the distance information acquisition unit 211.
　ステップＳ４では、状態特定部２３１がエレベータ制御盤２の状態の特定を行う。ステップＳ４では状態特定部２３１は距離情報記憶部２２１が記憶する最新の距離の検出値を用いて、状態判定情報に記憶された距離の正常値との大小関係からエレベータ制御盤２の状態を判断する。すなわち、状態特定部２３１は、エレベータ制御盤２が正常な状態、戸挟み状態、センサ不良状態、戸２１にゆがみが生じた状態、および戸開状態のいずれの状態にあるかを特定する。エレベータ制御装置２００は、エレベータ制御盤２の状態が正常な状態以外であると判断すると、ステップＳ５を実行し、正常な状態であると判断するとステップＳ６を実行する。 In step S4, the state specifying unit 231 specifies the state of the elevator control panel 2. In step S4, the state specifying unit 231 determines the state of the elevator control panel 2 from the magnitude relationship with the normal value of the distance stored in the state determination information by using the latest distance detection value stored in the distance information storage unit 221. do. That is, the state specifying unit 231 identifies whether the elevator control panel 2 is in a normal state, a door pinching state, a sensor defective state, a state in which the door 21 is distorted, or a door open state. When the elevator control device 200 determines that the state of the elevator control panel 2 is other than the normal state, it executes step S5, and when it determines that the state is normal, it executes step S6.
　ステップＳ５では、制御処理部２３２が表示部１０に状態特定部２３１の判定結果を表示させるよう表示制御部２４１に指示する。エレベータ制御装置２００は、ステップＳ５を実行した後、ステップＳ１に戻り、保守モードでの稼働を継続する。このように、エレベータ制御装置２００は、エレベータ制御盤２の状態が正常でないと状態特定部２３１が判定すると、制御処理部２３２が通常モードでの運転を阻止するため、戸挟みが生じている状態でエレベータ装置１の通常の稼働を防止することができる。 In step S5, the control processing unit 232 instructs the display control unit 241 to display the determination result of the state specifying unit 231 on the display unit 10. After executing step S5, the elevator control device 200 returns to step S1 and continues the operation in the maintenance mode. As described above, in the elevator control device 200, when the state specifying unit 231 determines that the state of the elevator control panel 2 is not normal, the control processing unit 232 prevents the operation in the normal mode, so that the door is pinched. Therefore, the normal operation of the elevator device 1 can be prevented.
　なお、ステップＳ５によって表示部１０にエレベータ制御盤２の状態の判定結果が正常ではないという判定結果が表示されたとき、保守員は判定結果に応じて適切な処置を行い、正常ではないと判定された原因を解消させる。適切な処置とは具体的には、戸２１がゆがんでいれば戸２１の修理または交換を行い戸閉する。異物９の戸挟みが生じていれば戸挟みを解消させ、戸閉する。戸開していれば戸閉する。センサ不良であれば、距離検出部２２の位置または状態を確認し必要に応じて距離検出部２２の交換または正常値の再設定等を行った後、戸閉する。 When a determination result indicating that the determination result of the state of the elevator control panel 2 is not normal is displayed on the display unit 10 in step S5, the maintenance staff takes appropriate measures according to the determination result and determines that the condition is not normal. Eliminate the cause. Specifically, if the door 21 is distorted, the door 21 is repaired or replaced and the door is closed. If the foreign matter 9 is pinched in the door, the pinching is eliminated and the door is closed. If the door is open, it will be closed. If the sensor is defective, the position or state of the distance detection unit 22 is confirmed, the distance detection unit 22 is replaced or the normal value is reset as necessary, and then the door is closed.
　ステップＳ６では、エレベータ制御装置２００は、保守員の指示通り通常モードでのエレベータ装置１の稼働を始める。 In step S6, the elevator control device 200 starts the operation of the elevator device 1 in the normal mode as instructed by the maintenance staff.
　ステップＳ７では、制御処理部２３２が保守モードへの切替操作がなされたか否かを判断する。制御処理部２３２が操作情報記憶部２２３から操作情報を取得し、保守モードへの切替操作がなされたと判断すると、エレベータ制御装置２００はステップＳ１に戻り保守モードでの稼働を継続する。一方、制御処理部２３２が保守モードへの切替操作がなされていないと判断すると、エレベータ制御装置２００はステップＳ８を実行する。 In step S7, the control processing unit 232 determines whether or not the operation for switching to the maintenance mode has been performed. When the control processing unit 232 acquires the operation information from the operation information storage unit 223 and determines that the operation for switching to the maintenance mode has been performed, the elevator control device 200 returns to step S1 and continues the operation in the maintenance mode. On the other hand, if the control processing unit 232 determines that the operation for switching to the maintenance mode has not been performed, the elevator control device 200 executes step S8.
　ステップＳ８にて、制御処理部２３２はエレベータ装置１の運転を停止する指示がなされたか否かを判断する。制御処理部２３２において停止指示がなされていないと判断されると、エレベータ制御装置２００はステップＳ６を実行し、通常モードでの稼働を継続する。一方、制御処理部２３２において停止指示がなされたと判断されると、エレベータ制御装置２００はエレベータ装置１の稼働を停止する。 In step S8, the control processing unit 232 determines whether or not an instruction to stop the operation of the elevator device 1 has been given. When the control processing unit 232 determines that the stop instruction has not been given, the elevator control device 200 executes step S6 and continues the operation in the normal mode. On the other hand, when it is determined that the control processing unit 232 has given the stop instruction, the elevator control device 200 stops the operation of the elevator device 1.
　以上のように、本開示の実施の形態１の状態判定装置２４およびエレベータ制御装置２００は、距離の検出値と正常値との大小関係を求め、状態判定情報を用いて、求めた大小関係に対応するエレベータ制御盤２の状態を判定するので、異物９の挟み込みだけでなく、戸２１のゆがみ等の状態も判定することができる。 As described above, the state determination device 24 and the elevator control device 200 of the first embodiment of the present disclosure obtain the magnitude relationship between the detected value of the distance and the normal value, and use the state determination information to obtain the magnitude relationship. Since the state of the corresponding elevator control panel 2 is determined, not only the state of the foreign matter 9 being caught but also the state of the door 21 being distorted can be determined.
　この結果、エレベータ装置１運転中の異物９の挟み込みによる故障、地絡事故を未然に防止し、機器の保護が可能となるだけでなく、異物９を挟み込んでいなくともエレベータ制御盤２の戸２１のゆがみ、センサ不良または戸開といったエレベータ制御盤２の不具合も検出でき、エレベータ制御盤２がとりうる異物９の挟み込み以外の異常状態も判定できるという効果がある。 As a result, failure and ground fault accidents due to pinching of foreign matter 9 during operation of the elevator device 1 can be prevented, and not only the equipment can be protected, but also the door of the elevator control panel 2 even if the foreign matter 9 is not pinched. There is an effect that defects of the elevator control panel 2 such as distortion of 21 and sensor failure or door opening can be detected, and an abnormal state other than the pinching of foreign matter 9 that can be taken by the elevator control panel 2 can be determined.
　エレベータ制御盤２がとりうる異物９の挟み込み以外の異常状態も判定できることで、保守員はエレベータ制御盤２を実際に確認しなくとも、エレベータ制御盤２の状態を詳細に知ることができる。これにより、例えば保守員がエレベータ制御盤２から離れた場所にいるとしても、表示部１０に表示されたエレベータ制御盤２の状態の情報を確認することで、事前に不具合を解消するために必要な道具を用意してからエレベータ制御盤２へ向かうことができる。また、エレベータ制御盤２が正常ではないと判定された場合に、異物９の挟み込み以外の異常状態も知ることができるので、エレベータ制御盤２を正常な状態にするための具体的な対応がとりやすく、不具合を解消して通常モードへ復帰させるまでの時間を短縮させることができる。 By being able to determine an abnormal state other than the pinching of foreign matter 9 that can be taken by the elevator control panel 2, the maintenance staff can know the state of the elevator control panel 2 in detail without actually checking the elevator control panel 2. As a result, for example, even if the maintenance staff is away from the elevator control panel 2, it is necessary to solve the problem in advance by checking the status information of the elevator control panel 2 displayed on the display unit 10. You can go to the elevator control panel 2 after preparing various tools. Further, when it is determined that the elevator control panel 2 is not normal, it is possible to know an abnormal state other than the pinching of the foreign matter 9, so specific measures are taken to bring the elevator control panel 2 to the normal state. It is easy, and the time required to resolve the problem and return to the normal mode can be shortened.
