Description

本発明は、エレベータの乗りかごにおけるかごドアの開閉動作に伴う異常音の診断を行うエレベータ用ドア診断システムに関する。   The present invention relates to an elevator door diagnostic system for diagnosing abnormal sounds associated with opening and closing operations of a car door in an elevator car.

一般に、エレベータは複数の摺動部を有しており、乗りかごの昇降運転や、かごドアの開閉動作が繰り返し行われるため、摺動部に油切れや変形が生じること、或いは異物が挟まること等により、かごドアの開閉動作時に異常音を発生することがある。特にかごドアの開閉端部は、開閉動作によりドア用レールの油かすが溜まり易いため、これが要因となって異常音を発生し易いことが知られている。   In general, an elevator has a plurality of sliding parts, and the car is lifted and lowered and the car door is opened and closed repeatedly. For example, abnormal sounds may be generated when the car door is opened or closed. In particular, it is known that the door opening / closing end of the car door is liable to accumulate oil residue on the door rail due to the opening / closing operation, and this is likely to cause abnormal noise.

通常、かごドアの開閉動作時に異常音が発生すると、エレベータの利用者や管理者により通報を受けた保守点検業者(技術員)が現地へ赴いて対処する。ところが、通報人である利用者や管理者が専門知識に乏しい場合も少なくなく、こうした場合には保守点検業者が事前情報を持たないため、現地で点検作業を開始するまでに異常音発生の原因を推定し難いこともしばしばある。特に、通報人の記憶が曖昧であったり、或いは不在であると、保守点検業者が現地で実際にエレベータを動かし、乗りかごを昇降運転して異常音の発生箇所を見つけることから始めなければならず、対処作業に多大な時間を要してしまうこともある。   Normally, when an abnormal sound is generated during the opening / closing operation of a car door, a maintenance / inspection company (technician) who receives a report from an elevator user or an administrator visits the site and takes action. However, there are many cases in which users and managers who are notifiers lack expertise, and in such cases, the maintenance inspection company does not have prior information, so the cause of abnormal noise generation by the time the inspection work is started on site. Is often difficult to estimate. In particular, if the memory of the whistleblower is ambiguous or absent, the maintenance and inspection contractor must actually start the elevator by moving the elevator up and down to find the location of abnormal noise. Therefore, it may take a lot of time for the coping operation.

そこで、異常音発生の認知を迅速化するための技術も提案されており、係る周知技術としては、ドア開閉音の異常を遠隔監視装置から確認できるようにした「エレベータ遠隔監視システム」(特許文献1参照)や、エレベータの運行中にエレベータの異常音を周辺で発生する音と区別して検出する「エレベータの異常音検出装置及び方法」(特許文献2参照)が挙げられる。   Therefore, a technique for speeding up the recognition of the occurrence of abnormal noise has also been proposed, and as a well-known technique, there is an “elevator remote monitoring system” in which a door monitoring sound abnormality can be confirmed from a remote monitoring device (Patent Literature). 1) and “an elevator abnormal sound detection device and method” (see Patent Document 2) that detects abnormal sounds of an elevator separately from sounds generated in the vicinity during operation of the elevator.

上述した特許文献1の技術では、エレベータのかご(乗りかご)内のインターホンを利用し、ドア開閉音の異常を電話回線を通して遠隔監視装置から確認する手法によるものであるため、乗客の会話や足音等のノイズが音声データに混在すると、ドア開閉動作時の異常音の発生を適確に診断することが困難になってしまうという問題がある。   In the technique of Patent Document 1 described above, the intercom in the elevator car (passenger car) is used to check for abnormalities in door opening and closing sound from a remote monitoring device through a telephone line. When noise such as the above is mixed in audio data, there is a problem that it is difficult to accurately diagnose the occurrence of abnormal noise during door opening and closing operations.

また、上述した特許文献2の技術では、エレベータのかご(乗りかご)内及びかご上に集音計を設置し、エレベータの運行状況に応じて各集音計で集音されたかご内音とかご上音とを比較してエレベータの異常音を検知するものであるため、ここでも乗客の会話や足音等のノイズが音声データに混在(特に共鳴したノイズが混在)すると、エレベータの異常音を適確に検知することが困難になってしまうという問題がある。   Moreover, in the technique of patent document 2 mentioned above, the sound collector is installed in the elevator car (riding car) and on the car, and the sound in the car collected by each sound collector according to the operation status of the elevator. Since the abnormal sound of the elevator is detected by comparing with the sound of the passenger, if noise such as passenger conversations and footsteps are mixed in the voice data (especially resonance noise is mixed), the abnormal sound of the elevator is also detected. There is a problem that it becomes difficult to detect accurately.

更に、特許文献1、特許文献2の何れの技術においても、かごドアと乗場ドアとを同時に開閉させて異常音の診断を行うため、異常音の発生箇所がかごドア側で生じているか、或いは乗場ドア側で生じているかを特定して判別するのが困難になっているという問題がある。   Furthermore, in either of the techniques of Patent Document 1 and Patent Document 2, since the abnormal sound is diagnosed by opening and closing the car door and the landing door at the same time, the location where the abnormal sound is generated occurs on the car door side, or There is a problem that it is difficult to identify and determine whether it occurs on the landing door side.

本発明は、このような問題点を解決すべくなされたもので、その技術的課題は、ノイズの混在を極力排除してエレベータの乗りかごにおけるかごドアとそれに係合されて連動する乗場ドアとの双方についての開閉動作における異常音を精度良く適確に診断できるエレベータ用ドア診断システムを提供することにある。   The present invention has been made to solve such problems, and the technical problem thereof is that a car door in an elevator car and a landing door that is engaged and interlocked with the car are eliminated as much as possible from mixing noise. It is an object of the present invention to provide an elevator door diagnosis system capable of accurately and accurately diagnosing abnormal noise in the opening / closing operation of both of the above.

上記技術的課題を解決するため、本発明の第1の手段は、エレベータの乗りかごにおけるかごドアの開閉動作を制御するドア制御装置と、乗りかごに設けられた集音手段によりかごドアと乗場ドアとについての開閉動作時の動作音を集音して音声データとして記録する音声データ記録手段、並びに当該音声データ記録手段により記録した音声データと当該集音手段により集音された新たな音声データとを比較した結果に基づいて診断を行う音声データ比較手段を有するドア診断装置と、を備えたエレベータ用ドア診断システムであって、乗りかごを走行させてかごドア及び乗場ドアが係合しない位置と係合する位置とで停止させる走行制御を行う走行制御装置を備え、ドア診断装置における音声データ比較手段は、走行制御装置により乗りかごをかごドア及び乗場ドアが係合しない位置へと走行させて停止させた状態でドア制御装置での当該かごドアの開閉動作時に得られる比較の診断結果として、当該かごドアの開閉動作時に異常なしと判定した場合に、当該走行制御装置により当該乗りかごを当該かごドア及び当該乗場ドアが係合する位置へと走行させて停止させた状態に移行した後、当該ドア制御装置での当該かごドア及び当該乗場ドアの開閉動作時に得られる当該比較の結果に基づいて当該乗場ドアの診断を行うことを特徴とする。   In order to solve the above technical problem, the first means of the present invention includes a door control device for controlling the opening / closing operation of a car door in an elevator car, and a car door and a landing by sound collecting means provided in the car. Sound data recording means for collecting operation sound at the time of opening / closing operation with the door and recording it as sound data, sound data recorded by the sound data recording means, and new sound data collected by the sound collecting means And a door diagnosis system having a voice data comparison means for making a diagnosis based on the result of the comparison, and a position where the car door and the landing door are not engaged when the car is run A travel control device that performs travel control to stop at a position where it engages, and the voice data comparison means in the door diagnostic device is driven by the travel control device. As a comparison diagnosis result obtained when opening and closing the car door with the door control device in a state where the car door and the landing door are moved to a position where they are not engaged and stopped, there is no abnormality during the opening and closing operation of the car door When the vehicle control device determines that the vehicle control device has moved to a state in which the vehicle control device has caused the car to travel to the position where the car door and the landing door are engaged and stopped, the car door in the door control device. In addition, the landing door is diagnosed based on the comparison result obtained during the opening / closing operation of the landing door.

本発明の第2の手段は、第1の手段において、走行制御装置及びドア診断装置に接続されて当該走行制御装置における乗りかごの走行状態を監視する監視装置を備え、監視装置は、音声データ比較手段へかごドア開閉音診断の実施を発令して当該走行制御装置に対してかごドア及び乗場ドアが係合しない階床間に乗りかごを走行させて停止させる指示、並びにドア制御装置による当該かごドアの開閉動作を行わせる指示を行った上で当該音声データ比較手段によるかごドア開閉時の当該かごドア開閉音診断を比較の結果により行わせ、更に、音声データ比較手段から送出されたかごドア開閉音診断の結果が正常状態であれば、当該音声データ比較手段へ乗場ドア開閉音診断の実施を発令して走行制御装置に対してかごドア及び乗場ドアが係合する階床に乗りかごを走行させて停止させる指示、並びにドア制御装置による当該かごドア及び当該乗場ドアの開閉動作を行わせる指示を行った上で当該音声データ比較手段による乗場ドア開閉時の当該乗場ドア開閉音診断を比較の結果により行わせることを特徴とする。   According to a second means of the present invention, in the first means, a monitoring device connected to the travel control device and the door diagnosis device and monitoring the traveling state of the car in the travel control device is provided. An instruction to perform the car door opening / closing sound diagnosis is issued to the comparison means, and an instruction is given to the travel control device to stop the car by running between the floors where the car door and the landing door are not engaged, and the door control device After giving an instruction to open / close the car door, the sound data comparison means performs the car door open / close sound diagnosis when the car door is opened / closed based on the comparison result, and the car sent from the sound data comparison means. If the result of the door opening / closing sound diagnosis is normal, the sound data comparison means is instructed to perform the landing door opening / closing sound diagnosis, and the car door and the landing door are engaged with the travel control device. An instruction to run and stop the car on the floor, and an instruction to open and close the car door and the landing door by the door control device, and the voice data comparing means when the landing door is opened and closed The hall door opening / closing sound diagnosis is performed based on the comparison result.

本発明の第3の手段は、第2の手段において、監視装置は、通信回線を介して管制システムに接続されると共に、音声データ比較手段から取得した比較の結果が異常を示す場合に当該通信回線を介して当該管制システムへ通報を行うことを特徴とする。   According to a third means of the present invention, in the second means, when the monitoring device is connected to the control system via a communication line and the comparison result obtained from the voice data comparing means indicates an abnormality, It is characterized by reporting to the control system via a line.

本発明の第4の手段は、第1の手段〜第3の手段の何れか1つの手段において、ドア診断装置における音声データ比較手段は、音声データ記録手段に音声データが記録されておらず、比較対象がない場合にはそのまま集音手段からの集音により得られた音声データを当該音声データ記録手段に記録すると共に、比較の結果を正常状態とみなすことを特徴とする。   According to a fourth means of the present invention, in any one of the first means to the third means, the sound data comparison means in the door diagnostic apparatus is such that sound data is not recorded in the sound data recording means, When there is no comparison target, the sound data obtained by collecting the sound from the sound collecting means is recorded in the sound data recording means, and the comparison result is regarded as a normal state.

本発明のエレベータ用ドア診断システムによれば、夜間等のエレベータが利用されない時間帯にかごドア及び乗場ドアが係合しない階床間に乗りかごを走行させて停止させた状態でかごドアのみを開閉させて集音した音声データに基づいて異常音の診断を行うため、保守点検時のノイズ混入を極力防止でき、かごドアの診断を精度良く行うことができる他、かごドアの診断結果が正常であると判定された場合にかごドア及び乗場ドアが係合する階床に乗りかごを走行させて停止させた状態でかごドア及び乗場ドアを開閉させて集音した音声データに基づいて乗場ドアの異常音の診断を行うため、異常音の発生箇所が乗場ドアである場合にも容易に判別できる。この結果、保守技術者がかごドア、乗場ドアの種別を問わずにドア開閉動作時の異常音の発生箇所を容易に認知できて迅速に対処できるため、エレベータの利用者に対して速やかに安全・安心を提供できることになり、産業上有益である。   According to the elevator door diagnostic system of the present invention, only the car door is stopped in a state where the car is run and stopped between floors where the car door and the landing door do not engage during the time when the elevator is not used such as at night. Abnormal sound is diagnosed based on the sound data collected by opening and closing, so noise contamination during maintenance and inspection can be prevented as much as possible, car door diagnosis can be performed with high accuracy, and the car door diagnosis result is normal The landing door is based on the sound data collected by opening and closing the car door and the landing door with the car running on the floor to which the car door and the landing door are engaged and stopped. Since the abnormal sound is diagnosed, it can be easily distinguished even when the abnormal sound is generated at the landing door. As a result, the maintenance engineer can easily recognize the location of the abnormal sound generated during door opening and closing operations and take prompt action regardless of the type of car door or landing door.・ Being able to provide peace of mind, it is beneficial to the industry.

以下に、本発明のエレベータ用ドア診断システムについて、実施例を挙げ、図面を参照して詳細に説明する。   Hereinafter, an elevator door diagnosis system according to the present invention will be described in detail with reference to the accompanying drawings.

図1は、本発明の実施例1に係るエレベータ用ドア診断システムの基本構成を示した概略ブロック図である。このエレベータ用ドア診断システムは、建物に設備された昇降路でかご用案内レール8に沿って昇降する乗りかご1におけるかごドア2のドア用案内レール7に沿った開閉動作を制御するドア制御装置6と、乗りかご1の昇降走行・停止を含む運転動作、並びに乗りかご1におけるかごドア2の開閉動作をドア制御装置6へ指示して制御する制御盤9と、制御盤9を通して乗りかご1の動作状態を監視すると共に、制御盤9に対する乗りかご1の昇降走行・停止を含む運転動作についての指令信号、並びにドア制御装置6に対する乗りかご1におけるかごドア2の開閉動作についての指令信号を送出する監視装置30と、監視装置30に対して通信回線としての電話回線11を介在して接続されると共に、遠隔した場所に設置される管制センタ12と、乗りかご1に設けられた集音手段(後述するかご内インターホン3のマイク機能)によりかごドア2と乗場ドアとについての開閉動作時の動作音を集音して音声データとして記録する音声データ記録手段10b、並びにこの音声データ記録手段10bにより記録した音声データと集音手段により集音された新たな音声データとを比較した結果に基づいて診断を行う音声データ比較手段10aを有するドア診断装置10と、を備えて構成される。   FIG. 1 is a schematic block diagram showing a basic configuration of an elevator door diagnostic system according to Embodiment 1 of the present invention. This elevator door diagnosis system is a door control device that controls the opening / closing operation of a car door 2 along a door guide rail 7 in a car 1 that moves up and down along a car guide rail 8 in a hoistway installed in the building. 6, a control panel 9 for instructing and controlling the door control device 6 to control the operation of the car 1, including running and stopping of the car 1, and the opening / closing operation of the car door 2 in the car 1, and the car 1 through the control board 9. The operation signal of the car 1 to the control panel 9 and the operation signal including the running / stop of the car 1 and the command signal to the door control device 6 about the opening / closing operation of the car door 2 in the car 1 are received. The monitoring device 30 to be transmitted and the control device 30 connected to the monitoring device 30 via a telephone line 11 as a communication line and installed in a remote place 12 and sound collecting means provided in the car 1 (microphone function of the intercom 3 in the car described later) collects the operation sound during the opening / closing operation of the car door 2 and the landing door and records it as voice data. A door having voice data recording means 10b and voice data comparison means 10a for making a diagnosis based on the result of comparing the voice data recorded by the voice data recording means 10b with the new voice data collected by the sound collecting means. And a diagnostic device 10.

このうち、乗りかご1内には、閉じ込め故障時等の非常事態発生時に乗員が外部の管理人室、管制センタ12等へ通報を行うための集音手段を兼用したかご内インターホン3が設けられており、乗りかご1外の天井付近にはかごドア2の開閉移動を案内するためのドア用案内レール7が設けられている。また、乗りかご1外の天井には、かごドア2を開閉駆動させるための電動機(モータ)5と、制御盤9からの制御指令を受けて電動機5を回転駆動して乗りかご2の開閉動作を制御するドア制御装置6と、が設置されている。   Among these, in the car 1, there is an interphone 3 in the car that also serves as a sound collecting means for the passenger to report to the outside management room, the control center 12, etc. in the event of an emergency such as a confinement failure. A door guide rail 7 for guiding the opening and closing movement of the car door 2 is provided near the ceiling outside the car 1. In addition, on the ceiling outside the car 1, an electric motor (motor) 5 for driving the car door 2 to open and close, and a motor 5 is driven to rotate in response to a control command from the control panel 9, and the car 2 is opened and closed. And a door control device 6 for controlling.

制御盤9のエレベータ制御回路9aは、エレベータの乗りかご1を建物に設備された昇降路のかご用案内レール8に沿って上下に走行させて乗場で停止させると、乗員を乗降させるためドア制御装置6を制御して電動機5を回転駆動させ、これにより乗りかご1のかごドア2と係合した略図する乗場ドアが連動して開閉する。それ故、制御盤9のエレベータ制御回路9aは、かごドア2及び乗場ドアが係合しない位置へと乗りかご1を走行させて停止させたり、或いは係合する位置へと走行させて停止させる走行制御を行う走行制御装置として機能する。   The elevator control circuit 9a of the control panel 9 controls the door so that the passenger can get on and off when the elevator car 1 runs up and down along the car guide rail 8 of the hoistway installed in the building and stops at the landing. The apparatus 6 is controlled to rotate and drive the electric motor 5, whereby the illustrated landing door engaged with the car door 2 of the car 1 is opened and closed in conjunction. Therefore, the elevator control circuit 9a of the control panel 9 causes the car 1 to travel to a position where the car door 2 and the landing door do not engage and stop, or travels to a position where it engages and stops. It functions as a travel control device that performs control.

監視装置30の監視回路30aは、エレベータ制御回路9aの制御情報を取得してエレベータの異常を監視し、異常を検出すると通信回路30b及び電話回線11を介して異常を管制センタ12に通報する。また、監視回路30aは、ドア診断装置10の音声データ比較手段10aにドア開閉音診断を実施するための指令を発出する。ドア診断装置10の音声データ比較手段10aは、エレベータ制御回路9aにより乗りかご1をかごドア2及び乗場ドアが係合しない位置へと走行させて停止させた状態でドア制御装置6でのかごドア2の開閉動作時に得られるかご内インターホン3のマイク(集音手段)により集音された音声データと音声データ記録手段10bに記録された音声データとを比較した診断結果として、かごドア2の開閉動作時に異常なしと判定した場合に、エレベータ制御回路9aにより乗りかご1をかごドア2及び乗場ドアが係合する位置へ走行させて停止させた状態に移行した後、ドア制御装置6でのかごドア2及び乗場ドアの開閉動作時に得られる集音された音声データと音声データ記録手段10bに記録された音声データとを比較した結果に基づいて乗場ドアの診断を行う。   The monitoring circuit 30a of the monitoring device 30 acquires the control information of the elevator control circuit 9a and monitors the abnormality of the elevator. When the abnormality is detected, the abnormality is reported to the control center 12 via the communication circuit 30b and the telephone line 11. In addition, the monitoring circuit 30a issues a command for performing door opening / closing sound diagnosis to the sound data comparison means 10a of the door diagnosis device 10. The voice data comparison means 10a of the door diagnostic device 10 is a car door in the door control device 6 in a state in which the elevator control circuit 9a causes the car 1 to travel to a position where the car door 2 and the landing door are not engaged and is stopped. As a result of diagnosis comparing the voice data collected by the microphone (sound collecting means) of the interphone 3 in the car and the voice data recorded in the voice data recording means 10b obtained during the opening / closing operation of the car 2, the opening / closing of the car door 2 is performed. When it is determined that there is no abnormality during operation, the elevator control circuit 9a causes the car 1 to travel to a position where the car door 2 and the landing door are engaged and stopped, and then the car in the door control device 6 is used. Based on the result of comparing the collected voice data obtained during the opening / closing operation of the door 2 and the landing door with the voice data recorded in the voice data recording means 10b. Hall make a diagnosis of the door.

また、音声データ比較手段10aは、集音した新音声データと音声データ記録手段10bに記録された旧音声データとを比較してドア開閉音診断(後述するかごドア開閉音診断、乗場ドア開閉音診断)を実施した結果を監視回路30aに送出する。これにより、監視回路30aは、音声データ比較手段10aから取得した比較の結果(ドア開閉音診断結果)に異常があると、通信回線30b及び電話回線11を介して異常を管制センタ12に通報する。異常が通報された管制センタ12では、異常検出されたエレベータの乗りかご1を調査するように担当の保守点検員に連絡する。   The voice data comparison means 10a compares the collected new voice data with the old voice data recorded in the voice data recording means 10b, thereby making a door opening / closing sound diagnosis (car door opening / closing sound diagnosis, landing door opening / closing sound described later). The result of executing (diagnosis) is sent to the monitoring circuit 30a. Thereby, if there is an abnormality in the comparison result (door opening / closing sound diagnosis result) acquired from the voice data comparison unit 10a, the monitoring circuit 30a reports the abnormality to the control center 12 via the communication line 30b and the telephone line 11. . In the control center 12 in which the abnormality is reported, the maintenance inspector in charge is contacted so as to investigate the elevator car 1 in which the abnormality is detected.

ところで、監視回路30aは、ドア診断装置10の音声データ比較手段10aへかごドア開閉音診断の実施を発令してエレベータ制御回路9aに対してかごドア2及び乗場ドアが係合しない階床間に乗りかご1を走行させて停止させる指示、並びにドア制御装置6によるかごドア2の開閉動作を行わせる指示を行う。かごドア2が開閉されると、ドア診断装置10の音声データ比較手段10aがかご内インターホン3から集音した音声データ(新音声データ)を音声データ記録手段10bに記録されている音声データ(旧音声データ)と比較して異常音の検出を行う。ここでの音声データは、時間軸に対するかごドア2の開閉音の音圧の推移データである。   By the way, the monitoring circuit 30a issues a car door opening / closing sound diagnosis to the voice data comparison means 10a of the door diagnostic device 10 and between the floors where the car door 2 and the landing door are not engaged with the elevator control circuit 9a. An instruction to make the car 1 run and stop, and an instruction to open and close the car door 2 by the door control device 6 are given. When the car door 2 is opened and closed, the voice data (old voice data) collected by the voice data comparison means 10a of the door diagnostic apparatus 10 from the interphone 3 in the car is recorded in the voice data recording means 10b (old data) Abnormal sound is detected in comparison with audio data. The sound data here is transition data of the sound pressure of the opening / closing sound of the car door 2 with respect to the time axis.

音声データ比較手段10aは、音声データ記録手段10bに音声データ(旧音声データ)が記録されていなければ、集音した音声データ(新音声データ)の比較は行わずにそれを音声データ記録手段10bに記録するようにして、比較結果を正常とする。また、音声データ記録手段10bに音声データ(旧音声データ)が記録されていれば、集音した音声データ(新音声データ)を音声データ記録手段10bに記録されている音声データ(旧音声データ)と比較し、その結果が予め定めた数値以上の差異があると異常音の検出とし、差異がなければ正常状態とみなし、何れの結果についても監視装置30の監視回路30aへ送出する。監視回路30aは、かごドア2が正常であればその旨を記録してからかごドア開閉音診断を終了し、管制センタ12への通報を行わないが、かごドア2で異常音が検出されればその旨を記録してかごドア2に対するかごドア開閉音診断を終了した後、通信回路30b及び電話回線11を介して管制センタ12へ異常検出の旨を通報する。かごドア開閉音診断の終了時には音声データ比較手段10aによる比較結果の内容に拘らず、監視回路30aがエレベータ制御回路9aにエレベータの利用復帰を指示し、エレベータ制御回路9aが乗りかご1を最寄りの乗場階床に乗りかご1を走行させて停止する。尚、かごドア開閉音診断の結果、異常検出された場合には、乗場ドアに対する乗場ドア開閉音診断は実施しない。   If no voice data (old voice data) is recorded in the voice data recording means 10b, the voice data comparison means 10a does not compare the collected voice data (new voice data) and does not compare the voice data recording means 10b. To make the comparison result normal. If voice data (old voice data) is recorded in the voice data recording means 10b, the collected voice data (new voice data) is recorded as voice data (old voice data) in the voice data recording means 10b. If there is a difference greater than or equal to a predetermined numerical value, abnormal sound is detected, and if there is no difference, it is regarded as a normal state, and any result is sent to the monitoring circuit 30a of the monitoring device 30. If the car door 2 is normal, the monitoring circuit 30a ends the car door opening / closing sound diagnosis after recording that fact, and does not notify the control center 12, but an abnormal sound is detected at the car door 2. For example, after recording the fact and ending the car door opening / closing sound diagnosis for the car door 2, the control center 12 is notified of the abnormality detection via the communication circuit 30b and the telephone line 11. At the end of the car door opening / closing sound diagnosis, the monitoring circuit 30a instructs the elevator control circuit 9a to return to use of the elevator regardless of the contents of the comparison by the voice data comparison means 10a, and the elevator control circuit 9a Run the car 1 on the landing floor and stop. If an abnormality is detected as a result of the car door opening / closing sound diagnosis, the landing door opening / closing sound diagnosis for the landing door is not performed.

ドア診断装置10の音声データ比較手段10aから送出されたかごドア開閉音診断の結果、正常状態であれば、監視回路30aは、ドア診断装置10の音声データ比較手段10aに乗場ドア開閉音診断の実施を発令してエレベータ制御回路9aに対してかごドア2及び乗場ドアが係合する階床に乗りかご1を走行させて停止させる指示、並びにドア制御装置6によるかごドア2及び乗場ドアの開閉動作を行わせる指示(かごドア2に対して乗場ドアが連動するため、かごドア2のみの対象とみなせる)を行う。例えば乗りかご1を最下階床から最上階床まで各階床に走行させて停止させ、かごドア2及び乗場ドアが各階床毎に開閉されたときにドア診断装置10の音声データ比較手段10aがかご内インターホン3から集音した音声データ(新音声データ)を音声データ記録手段10bに記録されている音声データ(旧音声データ)と比較して異常音の検出を行う。ここでの音声データも、時間軸に対する乗場ドアの開閉音の音圧の推移データである。   If the result of the car door opening / closing sound diagnosis sent from the sound data comparison means 10a of the door diagnostic device 10 is normal, the monitoring circuit 30a will check the sound data comparison means 10a of the door diagnosis device 10 for the landing door opening / closing sound diagnosis. An instruction is issued to the elevator control circuit 9a to stop the car 1 by running on the floor to which the car door 2 and the landing door are engaged, and the door control device 6 opens and closes the car door 2 and the landing door. An instruction to perform the operation (the landing door is interlocked with the car door 2 so that the car door 2 can be regarded as an object only). For example, when the car 1 is run on each floor from the lowest floor to the top floor and stopped, and the car door 2 and the landing door are opened and closed for each floor, the voice data comparing means 10a of the door diagnostic device 10 is used. Abnormal sound is detected by comparing the sound data (new sound data) collected from the interphone 3 in the car with the sound data (old sound data) recorded in the sound data recording means 10b. The sound data here is also transition data of the sound pressure of the landing door opening / closing sound with respect to the time axis.

音声データ比較手段10aは、音声データ記録手段10bに音声データ(旧音声データ)が記録されていなければ、集音した音声データ(新音声データ)の比較は行わずにそれを音声データ記録手段10bに記録するようにして、比較結果を正常とする。また、音声データ記録手段10bに音声データ(旧音声データ)が記録されていれば、集音した音声データ(新音声データ)を音声データ記録手段10bに記録されている音声データ(旧音声データ)と比較し、その結果が予め定めた数値以上の差異があると異常音の検出とし、差異がなければ正常状態とみなし、何れの結果についても監視装置30の監視回路30aへ送出する。監視回路30aは、乗場ドアが正常であればその旨を記録してから乗場ドア開閉音診断を終了し、管制センタ12への通報を行わないが、各階床の何れかの乗場ドアで異常音が検出されればその旨(現在開閉している乗場ドア)を記録して乗場ドアに対する乗場ドア開閉音診断を終了した後、通信回路30b及び電話回線11を介して管制センタ12へ異常検出の旨を通報する。   If no voice data (old voice data) is recorded in the voice data recording means 10b, the voice data comparison means 10a does not compare the collected voice data (new voice data) and does not compare the voice data recording means 10b. To make the comparison result normal. If voice data (old voice data) is recorded in the voice data recording means 10b, the collected voice data (new voice data) is recorded as voice data (old voice data) in the voice data recording means 10b. If there is a difference greater than or equal to a predetermined numerical value, abnormal sound is detected, and if there is no difference, it is regarded as a normal state, and any result is sent to the monitoring circuit 30a of the monitoring device 30. The monitoring circuit 30a records the fact that the landing door is normal and then terminates the landing door opening / closing sound diagnosis and does not report to the control center 12. Is detected and the landing door opening / closing sound diagnosis for the landing door is completed, and then the control center 12 detects the abnormality via the communication circuit 30b and the telephone line 11. Report to that effect.

図2は、監視装置30の監視回路30aにおけるかごドア診断に要する動作処理を一部ドア診断装置10の音声データ比較手段10aにおけるかごドア診断の動作処理に推移される様子を含めて示したフローチャートである。監視回路30aでは、まずドア診断装置10の音声データ比較手段10aにおける比較結果の情報に基づいて、前回のドア診断実施から予め定めた期間を経過したか否かによりドア診断開始時期か否かの判定(ステップS100)を行う。この判定の結果、ドア診断開始時期でなければ、この処理(ステップS100)の前にリターンして待機するが、ドア診断開始時期であれば、引き続いて夜間等の実施可能時間帯か否かの判定(ステップS101)を行う。因みに、実施可能時間帯はエレベータが設備されているビルの用途により異なるものであるため、ビル毎に設定することが可能なものである。この判定の結果、実施可能時間帯でなければ、この処理(ステップS101)の前にリターンして待機するが、実施可能時間帯であれば、引き続いてエレベータは未使用状態であるか否かの判定(ステップS102)を行う。因みに、エレベータの未使用状態とは、呼び無し状態が3分以上継続した場合を示すものである。この判定の結果、未使用状態でなければ、この処理(ステップS102)の前にリターンして待機するが、未使用状態であれば、引き続いて現在のかご位置は最下階か否かの判定(ステップS103)を行う。この判定の結果、最下階でなければ最下階のかご呼びを作成して制御盤9のエレベータ制御回路9aに指示して最下階までかご走行(ステップS104)させるようにしてから現在のかご位置は最下階か否かの判定(ステップS103)の前にリターンして処理を繰り返すが、最下階であればエレベータ制御回路9aに保守運転指令を指示してエレベータを保守運転に設定(ステップS105)する。   FIG. 2 is a flowchart showing a state in which an operation process required for car door diagnosis in the monitoring circuit 30a of the monitoring apparatus 30 is partially transferred to an operation process of car door diagnosis in the audio data comparison unit 10a of the door diagnosis apparatus 10. It is. The monitoring circuit 30a first determines whether or not it is the door diagnosis start time based on whether or not a predetermined period has elapsed since the previous door diagnosis based on the information of the comparison result in the voice data comparison means 10a of the door diagnosis device 10. Determination (step S100) is performed. As a result of this determination, if it is not the door diagnosis start time, it returns and waits before this processing (step S100), but if it is the door diagnosis start time, it is subsequently determined whether it is an available time zone such as at night. Determination (step S101) is performed. Incidentally, since the possible time zone varies depending on the use of the building where the elevator is installed, it can be set for each building. If the result of this determination is that it is not in a workable time zone, the process returns and waits before this processing (step S101), but if it is in a workable time zone, whether or not the elevator is in an unused state subsequently. A determination is made (step S102). Incidentally, the unused state of the elevator indicates a case where the no-call state continues for 3 minutes or more. If the result of this determination is that it is not in the unused state, the process returns and waits before this processing (step S102), but if it is in the unused state, it is subsequently determined whether or not the current car position is the lowest floor. (Step S103) is performed. If the result of this determination is that it is not the lowest floor, a car call for the lowest floor is created and the elevator control circuit 9a of the control panel 9 is instructed to drive the car to the lowest floor (step S104) and then the current Before the determination whether the car position is the lowest floor (step S103), the process is repeated and the process is repeated. However, if it is the lowest floor, the elevator control circuit 9a is instructed to perform a maintenance operation command and the elevator is set to the maintenance operation. (Step S105).

また、監視回路30aは、保守運転上昇走行指令を制御盤9のエレベータ制御回路9aに指示して最下階と直上階の中間位置まで走行したか否かの判定(ステップS106)を行う。この判定の結果、中間位置まで走行していなければ、この処理(ステップS106)の前にリターンして判定処理を繰り返すが、中間位置まで走行していれば、監視回路30aは、乗りかご1を停止させるかご停止(ステップS107)を行った後、かごドア開閉・異常監視(ステップS108)を制御盤9のエレベータ制御回路9aに指示してドア制御装置6によるかごドア2の開閉動作を行わせると共に、ドア診断装置10の音声データ比較手段10aに対してかごドア開閉音診断の実施を指示してドア開閉動作音診断(ステップS200)を行わせる。このドア開閉動作音診断(ステップS200)については、後文で詳述するが、係る診断の結果、ドア開閉動作音に異常があれば、監視回路30aは通信手段30b及び電話回線11を介して管制センタ11へ通報する。かごドア開閉・異常監視(ステップS108)を行った後、監視回路30aは、保守運転下降走行指令を制御盤9のエレベータ制御回路9aに指示して乗りかご1を最下階まで走行したか否かの判定(ステップS109)を行う。この判定の結果、最下階まで走行していなければ、この処理(ステップS109)の前にリターンして判定処理を繰り返すが、最下階で走行していれば、乗りかご1を停止させてかごドア開閉音診断を終了するものとし、エレベータ制御回路9aに通常運転指令を指示してエレベータを通常運転モードに設定(ステップS110)して動作処理を終了する。   Further, the monitoring circuit 30a instructs the elevator control circuit 9a of the control panel 9 to issue a maintenance operation ascending travel command, and determines whether or not the vehicle has traveled to an intermediate position between the lowest floor and the directly above floor (step S106). As a result of this determination, if the vehicle has not traveled to the intermediate position, the process returns to this process (step S106) and repeats the determination processing. However, if the vehicle has traveled to the intermediate position, the monitoring circuit 30a After the car is stopped (step S107), the car door opening / closing / abnormality monitoring (step S108) is instructed to the elevator control circuit 9a of the control panel 9 to cause the door control device 6 to open and close the car door 2. At the same time, the voice data comparing means 10a of the door diagnostic apparatus 10 is instructed to perform the car door opening / closing sound diagnosis to perform the door opening / closing operation sound diagnosis (step S200). The door opening / closing operation sound diagnosis (step S200) will be described in detail later. If the result of the diagnosis is that there is an abnormality in the door opening / closing operation sound, the monitoring circuit 30a is connected via the communication means 30b and the telephone line 11. Report to the control center 11. After performing the car door opening / closing / abnormality monitoring (step S108), the monitoring circuit 30a instructs the elevator control circuit 9a of the control panel 9 to issue a maintenance operation lowering traveling command and has traveled the car 1 to the lowest floor. Is determined (step S109). If the result of this determination is that the vehicle has not traveled to the lowest floor, the process returns to this process (step S109) and repeats the determination processing. If the vehicle is traveling on the lowest floor, the car 1 is stopped. The car door opening / closing sound diagnosis is to be terminated, a normal operation command is instructed to the elevator control circuit 9a, the elevator is set to the normal operation mode (step S110), and the operation process is terminated.

図3は、図2に示した監視装置30の監視回路30aにおける動作処理に含まれるかごドア開閉・異常監視(ステップS108)処理の細部とそれに相関して実施されるドア診断装置10の音声データ比較手段10aにおけるかごドア診断であるドア開閉動作音診断(ステップS200)の動作処理との細部とを対比して示したフローチャートである。図3を参照すれば、監視回路30aによるかごドア開閉・異常監視(ステップS108)の細部では、まず乗りかご1のかごドア2を開端まで開動作させるように制御盤9のエレベータ制御回路9aに指示してドア開制御(ステップS108−1)を行い、このときにドア診断装置10の音声データ比較手段10aがかご内インターホン3の集音手段であるマイクからドア開動作音を集音し、音声データ記録手段10bに記録することでドア開動作音集音し記録(ステップS201)する処理を行う。また、監視回路30aでは、かごドア2を開端まで開いたか否かを開端までドア開いたか否かの判定(ステップS108−2)により行う。この判定の結果、開端までドアが開いていなければ、ドア開制御(ステップS108−1)の前にリターンしてその後の処理を繰り返すが、開端までドアが開いていれば、乗りかご1のかごドア2を閉端まで閉動作させるように制御盤9のエレベータ制御回路9aに指示してドア閉制御(ステップS108−3)を行い、このときにドア診断装置10の音声データ比較手段10aがかご内インターホン3の集音手段であるマイクからドア閉動作音を集音し、音声データ記録手段10bに記録することでドア閉動作音集音し記録(ステップS202)する処理を行う。更に、監視回路30aでは、かごドア2を閉端まで閉じたか否かを閉端までドア閉じたか否かの判定(ステップS108−4)により行う。この判定の結果、閉端までドアが閉じていなければ、ドア閉制御(ステップS108−3)の前にリターンしてその後の処理を繰り返すが、閉端までドアが閉じていれば診断結果異常有りか否かの判定(ステップS108−5)をドア診断装置10の音声データ比較手段10aから取得して行う。   FIG. 3 shows details of the car door opening / closing / abnormality monitoring (step S108) process included in the operation process in the monitoring circuit 30a of the monitoring apparatus 30 shown in FIG. It is the flowchart which contrasted and showed the detail with the operation | movement process of the door opening / closing operation sound diagnosis (step S200) which is a car door diagnosis in the comparison means 10a. Referring to FIG. 3, in the details of the car door opening / closing / abnormality monitoring (step S108) by the monitoring circuit 30a, the elevator control circuit 9a of the control panel 9 is first opened so as to open the car door 2 of the car 1 to the open end. The door opening control (step S108-1) is instructed, and at this time, the voice data comparing means 10a of the door diagnostic device 10 collects the door opening operation sound from the microphone that is the sound collecting means of the car interphone 3, By recording in the audio data recording means 10b, the door opening operation sound is collected and recorded (step S201). The monitoring circuit 30a determines whether the car door 2 has been opened to the open end by determining whether the door has been opened to the open end (step S108-2). As a result of this determination, if the door is not open to the open end, the process returns to the door open control (step S108-1) and the subsequent processing is repeated. If the door is open to the open end, the car in the car 1 The elevator control circuit 9a of the control panel 9 is instructed to close the door 2 to the closed end, and door closing control (step S108-3) is performed. At this time, the voice data comparing means 10a of the door diagnostic device 10 is operated by the car. The door closing operation sound is collected from the microphone, which is the sound collecting means of the intercom 3, and recorded in the audio data recording means 10b to collect and record the door closing operation sound (step S202). Further, the monitoring circuit 30a determines whether or not the car door 2 is closed to the closed end by determining whether or not the door is closed to the closed end (step S108-4). As a result of this determination, if the door is not closed to the closed end, the process returns to the door closing control (step S108-3) and the subsequent processing is repeated, but if the door is closed to the closed end, there is an abnormality in the diagnosis result. Whether or not (step S108-5) is obtained from the voice data comparison means 10a of the door diagnostic apparatus 10.

音声データ比較手段10aでは、それ以前の処理で得られた記録された新音声データと音声データ記録手段10bに記録されている旧音声データとを比較し、その差異が所定の値を超えているか否かによりドア開閉音比較異常有りか否かの判定(ステップS203)を行う。この判定の結果、ドア開閉音比較に異常がなければ、診断結果正常(ステップS204)とみなし、ドア開閉音比較に異常があれば、診断結果異常(ステップS205)とみなすが、何れの結果についても監視装置30の監視回路30aに結果出力(ステップS206)して送信する。因みに、上述したように、ドア開閉音比較異常有りか否かの判定(ステップS203)に際して、音声データ記録手段10bに旧音声データが記録されておらず、比較対象がない場合にはそのまま集音した新音声データを音声データ記録手段10bに記録するようにしてから正常状態とみなすものである。そこで、監視回路30aによる診断結果異常有りか否かの判定(ステップS108−5)の結果、異常がなければ動作処理を終了するが、異常があれば通信回線10b及び電話回線11を介して管制センタ12に通報処理してから動作処理を終了する。   The voice data comparison means 10a compares the recorded new voice data obtained in the previous processing with the old voice data recorded in the voice data recording means 10b, and whether the difference exceeds a predetermined value. Whether or not there is a door opening / closing sound comparison abnormality is determined (step S203). As a result of the determination, if there is no abnormality in the door opening / closing sound comparison, the diagnosis result is regarded as normal (step S204). If there is an abnormality in the door opening / closing sound comparison, the diagnosis result is regarded as abnormal (step S205). The result is also output to the monitoring circuit 30a of the monitoring device 30 (step S206) and transmitted. Incidentally, as described above, when it is determined whether or not there is a door opening / closing sound comparison abnormality (step S203), if the old audio data is not recorded in the audio data recording means 10b and there is no comparison target, the sound collection is performed as it is. The new voice data thus recorded is recorded in the voice data recording means 10b, and is regarded as a normal state. Therefore, as a result of determining whether there is an abnormality in the diagnosis result by the monitoring circuit 30a (step S108-5), if there is no abnormality, the operation process is terminated. After the notification process to the center 12, the operation process is terminated.

図4は、監視装置30の監視回路30aにおける乗場ドア診断に要する動作処理を一部ドア診断装置10の音声データ比較手段10aにおける乗場ドア診断の動作処理に推移される様子を含めて示したフローチャートである。監視回路30aでは、まず先の図2に示す動作処理の最終段階で乗りかご1を最下階まで走行させて停止させた状態でエレベータを通常運転モードに設定(ステップS110)しているため、これらの処理は監視回路30aがドア診断装置10の音声データ比較手段10aに乗場ドア開閉音診断の実施を発令するため、エレベータ制御回路9aに対してかごドア2及び乗場ドアが係合する階床に乗りかご1を走行させて最下階に停止させる指示を行ったことに該当する。そこで、監視回路30aは、ここでは最下階でかごドア2・乗場ドア開閉・異常監視(ステップS301)処理を制御盤9のエレベータ制御回路9aに指示してドア制御装置6によるかごドア2・乗場ドアの開閉動作を行わせると共に、ドア診断装置10の音声データ比較手段10aに対して乗場ドア開閉音診断の実施を指示してドア開閉動作音診断(ステップS400)を行わせる。このドア開閉動作音診断(ステップS400)については、後文で詳述する。   FIG. 4 is a flowchart showing a state in which an operation process required for the landing door diagnosis in the monitoring circuit 30a of the monitoring apparatus 30 is partially transferred to an operation process of the landing door diagnosis in the voice data comparison unit 10a of the door diagnosis apparatus 10. It is. In the monitoring circuit 30a, the elevator is set to the normal operation mode with the car 1 traveling to the lowest floor at the final stage of the operation process shown in FIG. 2 (step S110). In these processes, the monitoring circuit 30a instructs the voice data comparison means 10a of the door diagnostic device 10 to perform the landing door opening / closing sound diagnosis, so that the car door 2 and the landing door are engaged with the elevator control circuit 9a. This corresponds to instructing the car 1 to travel to stop at the lowest floor. Therefore, here, the monitoring circuit 30a instructs the elevator control circuit 9a of the control panel 9 to perform the car door 2 / landing door opening / closing / abnormality monitoring (step S301) processing on the lowest floor, and the car door 2 / The opening / closing operation of the landing door is performed, and the voice data comparison unit 10a of the door diagnosis device 10 is instructed to perform the landing door opening / closing sound diagnosis to perform the door opening / closing operation sound diagnosis (step S400). This door opening / closing operation sound diagnosis (step S400) will be described in detail later.

監視回路30aは、最下階でのかごドア2・乗場ドア開閉・異常監視(ステップS301)処理の後、現在のかご位置は最上階か否かの判定(ステップS302)を行う。この判定の結果、最上階でなければ直上階のかご呼びを作成して制御盤9のエレベータ制御回路9aに指示して直上階へ走行(ステップS303)させ、次に直上階でかごドア2・乗場ドア開閉・異常監視(ステップS301)の前にリターンして処理を繰り返すことにより、直上階から最上階に至る各階床で乗場ドア開閉音診断が実施されるようにするが、最上階であれば、引き続いて監視回路30aによる診断結果異常有りか否かの判定(ステップS304)の結果、異常がなければ動作処理を終了するが、異常があれば通信回線10b及び電話回線11を介して管制センタ12に通報処理してから動作処理を終了する。   The monitoring circuit 30a determines whether the current car position is on the top floor (step S302) after the car door 2 / landing door opening / closing / abnormality monitoring (step S301) process on the bottom floor. If the result of this determination is that it is not the top floor, a car call on the floor directly above is created and directed to the elevator control circuit 9a of the control panel 9 to travel to the floor directly above (step S303). By returning and repeating the process before the landing door opening / closing / abnormality monitoring (step S301), the floor door opening / closing sound diagnosis is performed on each floor from the directly above floor to the top floor. If the result of the determination by the monitoring circuit 30a is that there is an abnormality in the monitoring circuit 30a (step S304), if there is no abnormality, the operation process is terminated, but if there is an abnormality, control is performed via the communication line 10b and the telephone line 11. After the notification process to the center 12, the operation process is terminated.

図5は、図4に示した監視装置30の監視回路30aにおける動作処理に含まれるかごドア2・乗場ドアの開閉・異常監視(ステップS301)処理の細部とそれに相関して実施されるドア診断装置10の音声データ比較手段10aにおける乗場ドア診断であるドア開閉動作音診断(ステップS400)の動作処理との細部を対比して示したフローチャートである。図5を参照すれば、監視回路30aによるかごドア2・乗場ドア開閉・異常監視(ステップS301)の細部では、まず乗りかご1のかごドア2を開端まで開動作(乗場ドアも係合して連動する)させるように制御盤9のエレベータ制御回路9aに指示してドア開制御(ステップS301−1)を行い、このときにドア診断装置10の音声データ比較手段10aがかご内インターホン3の集音手段であるマイクからドア開動作音を集音し、音声データ記録手段10bに記録することでドア開動作音集音し記録(ステップS401)する処理を行う。また、監視回路30aでは、かごドア2を開端まで開いたか否かを開端までドア開いたか否かの判定(ステップS301−2)により行う。この判定の結果、開端までドアが開いていなければ、ドア開制御(ステップS301−1)の前にリターンしてその後の処理を繰り返すが、開端までドアが開いていれば、乗りかご1のかごドア2を閉端まで閉動作(乗場ドアも係合して連動する)させるように制御盤9のエレベータ制御回路9aに指示してドア閉制御(ステップS301−3)を行い、このときにドア診断装置10の音声データ比較手段10aがかご内インターホン3の集音手段であるマイクからドア閉動作音を集音し、音声データ記録手段10bに記録することでドア閉動作音集音し記録(ステップS402)する処理を行う。更に、監視回路30aでは、かごドア2を閉端まで閉じたか否かを閉端までドア閉じたか否かの判定(ステップS301−4)により行う。この判定の結果、閉端までドアが閉じていなければ、ドア閉制御(ステップS301−3)の前にリターンしてその後の処理を繰り返すが、閉端までドアが閉じていれば診断結果を記録(ステップS301−5)する処理をドア診断装置10の音声データ比較手段10aから診断結果を取得して行ってから、1階床分のドア診断動作処理を終了する。   FIG. 5 shows details of the car door 2 / landing door opening / closing / abnormality monitoring (step S301) processing included in the operation processing in the monitoring circuit 30a of the monitoring device 30 shown in FIG. It is the flowchart which contrasted and showed the detail with the operation | movement process of the door opening / closing operation sound diagnosis (step S400) which is a landing door diagnosis in the audio | voice data comparison means 10a of the apparatus 10. FIG. Referring to FIG. 5, in the details of the car door 2 / the landing door opening / closing / abnormality monitoring (step S301) by the monitoring circuit 30a, first, the car door 2 of the car 1 is opened to the open end (the landing door is also engaged). The elevator control circuit 9a of the control panel 9 is instructed to perform the door opening control (step S301-1) so that the voice data comparison means 10a of the door diagnostic apparatus 10 collects the interphones 3 in the car. The door opening operation sound is collected from the microphone, which is the sound means, and recorded in the audio data recording means 10b, whereby the door opening operation sound is collected and recorded (step S401). The monitoring circuit 30a determines whether the car door 2 has been opened to the open end by determining whether the door has been opened to the open end (step S301-2). As a result of this determination, if the door is not open to the open end, the process returns to the door open control (step S301-1) and the subsequent processing is repeated. If the door is open to the open end, the car of the car 1 The elevator control circuit 9a of the control panel 9 is instructed to close the door 2 to the closed end (the landing door is also engaged and interlocked), and door closing control (step S301-3) is performed. The voice data comparison means 10a of the diagnostic apparatus 10 collects the door closing operation sound from the microphone which is the sound collecting means of the car interphone 3, and records it in the voice data recording means 10b to collect and record the door closing operation sound ( Step S402) is performed. Further, the monitoring circuit 30a determines whether or not the car door 2 is closed to the closed end by determining whether or not the door is closed to the closed end (step S301-4). As a result of this determination, if the door is not closed to the closed end, the process returns to the door closing control (step S301-3) and the subsequent processing is repeated, but if the door is closed to the closed end, the diagnosis result is recorded. (Step S301-5) After performing the process of obtaining the diagnosis result from the voice data comparison unit 10a of the door diagnosis apparatus 10, the door diagnosis operation process for the first floor is completed.

音声データ比較手段10aでは、S401、S402の処理で得られた記録された新音声データと音声データ記録手段10bに記録されている旧音声データとを比較し、その差異が所定の値を超えているか否かにより特に乗場ドアを注目してドア開閉音比較異常有りか否かの判定(ステップS403)を行う。この判定の結果、乗場ドアを主としてドア開閉音比較に異常がなければ、診断結果正常(ステップS404)とみなし、同様に乗場ドアを主としてドア開閉音比較に異常があれば、診断結果異常(ステップS405)とみなすが、何れの結果についても監視装置30の監視回路30aに結果出力(ステップS206)して送信してから動作処理を終了する。因みに、上述したように、ここでも乗場ドアを主とするドア開閉音比較異常有りか否かの判定(ステップS403)に際して、音声データ記録手段10bに旧音声データが記録されておらず、比較対象がない場合にはそのまま集音した新音声データを音声データ記録手段10bに記録するようにしてから正常状態とみなすものである。そこで、ドア診断装置10の音声データ比較手段10aによる診断結果が引き渡された監視装置30の監視回路30aは、上述したように診断結果を記録(ステップS301−5)してから動作処理を終了する。この一連の動作を最下階から最上階まで実施する。   The audio data comparison unit 10a compares the recorded new audio data obtained in the processes of S401 and S402 with the old audio data recorded in the audio data recording unit 10b, and the difference exceeds a predetermined value. Whether or not there is a door opening / closing sound comparison abnormality is determined by paying particular attention to the landing door (step S403). If the result of this determination is that there is no abnormality mainly in the door opening / closing sound comparison, the diagnosis result is considered normal (step S404). Similarly, if there is an abnormality mainly in the door opening / closing sound comparison, the diagnosis result is abnormal (step S404). S405), any result is output to the monitoring circuit 30a of the monitoring device 30 (step S206) and transmitted, and the operation process is terminated. Incidentally, as described above, in this case as well, when it is determined whether there is a door opening / closing sound comparison abnormality mainly for the landing door (step S403), the old audio data is not recorded in the audio data recording means 10b, and the comparison target If there is no sound, the new sound data collected as it is is recorded in the sound data recording means 10b and then regarded as a normal state. Therefore, the monitoring circuit 30a of the monitoring device 30 to which the diagnosis result by the voice data comparison unit 10a of the door diagnosis device 10 has been delivered records the diagnosis result as described above (step S301-5) and ends the operation process. . This series of operations is performed from the lowest floor to the highest floor.

尚、上述した実施例1に係るエレベータ用ドア診断システムでは、かごドア2のドア開閉音診断を最下階床から行い、かごドア2及び乗場ドアのドア開閉音診断を最下階床から最上階床に至る各階床毎に行う場合を説明したが、これらはあくまでも一例であり、例えばかごドア2のドア開閉音診断を最上階床から行い、かごドア2及び乗場ドアのドア開閉音診断を最上階床から最下階床に至る各階床毎に行うように変更することも可能であるし、ビル設備によっては中途階床間で走行停止させて保守点検せざるを得ない場合もあるため、本発明のエレベータ用ドア診断システム実施例1で開示した構成のものに限定されない。また、実施例1に係るエレベータ用ドア診断システムでは、廉価に運用できる構成として、乗りかご1内に標準装備されているかご内インターホン3に備えられる集音手段のマイクを用いる場合を説明したが、通常かご内インターホン3はドア開閉方向の一端側に設置されるため、更に診断精度を向上させるために例えばドア開閉方向の他端側に別途マイクを設置するようにしても良い。   In the elevator door diagnosis system according to the first embodiment described above, the door opening / closing sound diagnosis of the car door 2 is performed from the lowermost floor, and the door opening / closing sound diagnosis of the car door 2 and the landing door is performed from the lowermost floor to the uppermost floor. The case where it is performed for each floor to the floor has been described, but these are only examples, for example, the door opening / closing sound diagnosis of the car door 2 is performed from the top floor, and the door opening / closing sound diagnosis of the car door 2 and the landing door is performed. It is possible to change it so that it is performed for each floor from the top floor to the bottom floor, and depending on the building equipment, it may be necessary to stop traveling between mid-floor floors for maintenance inspection The elevator door diagnosis system of the present invention is not limited to the one disclosed in the first embodiment. In the elevator door diagnosis system according to the first embodiment, the case where the microphone of the sound collecting means provided in the car interphone 3 provided as a standard in the car 1 is used as a configuration that can be operated at low cost has been described. Since the car interphone 3 is normally installed on one end side in the door opening / closing direction, a microphone may be separately installed on the other end side in the door opening / closing direction, for example, in order to further improve diagnosis accuracy.

何れにせよ、本発明のエレベータ用ドア診断システムによれば、監視装置30の監視回路30aの指示により、走行制御装置として働く制御盤9のエレベータ制御回路9aで夜間等のエレベータが利用されない時間帯にかごドア2及び乗場ドアが係合しない階床間に乗りかご1を走行させて停止させた状態において、ドア制御装置6でかごドア2のみを開閉させてドア診断装置10における音声データ比較手段10aが乗りかご1内のかご内インターホン3から集音した音声データ(ドア動作音データ)に基づいて異常音の診断を行うため、保守点検時のノイズ混入を極力防止でき、かごドア2の診断を精度良く行うことができる。また、かごドア2の診断結果が正常であると判定された場合に、継続して監視装置30の監視回路30aの指示により、エレベータ制御回路9aでかごドア2及び乗場ドアが係合する階床に乗りかご1を走行させて停止させた状態において、ドア制御装置6でかごドア2及び乗場ドアを開閉させて音声データ比較手段10aがかご内インターホン3から集音した音声データ(ドア動作音データ)に基づいて乗場ドアの異常音の診断を行うため、異常音の発生箇所が乗場ドアである場合にも容易に判別することができる。   In any case, according to the elevator door diagnosis system of the present invention, the elevator control circuit 9a of the control panel 9 that works as a travel control device is not used by an elevator at night or the like according to an instruction from the monitoring circuit 30a of the monitoring device 30. In a state where the car 1 is run and stopped between the floors where the car door 2 and the landing door are not engaged, only the car door 2 is opened and closed by the door control device 6, and voice data comparison means in the door diagnostic device 10. Since the abnormal sound is diagnosed based on the voice data (door operation sound data) collected from the interphone 3 in the car 1 by the car 10a, it is possible to prevent noise from being mixed during maintenance and inspection, and to diagnose the car door 2. Can be performed with high accuracy. Further, when it is determined that the diagnosis result of the car door 2 is normal, the floor where the car door 2 and the landing door are engaged in the elevator control circuit 9a is continuously instructed by the monitoring circuit 30a of the monitoring device 30. In the state where the car 1 is run and stopped, the door control device 6 opens and closes the car door 2 and the landing door, and the voice data comparing means 10a collects sound data (door operation sound data) from the interphone 3 in the car. ), The abnormal sound of the landing door is diagnosed. Therefore, even when the abnormal sound is generated at the landing door, it can be easily determined.
