Description

本発明は、エレベータの着床時の段差を計測し異常の判定を行うエレベータ異常検出装置に関する。   The present invention relates to an elevator abnormality detection device that measures a level difference when landing an elevator and determines an abnormality.

一般にエレベータには、乗かご側に遮蔽板検出器、昇降路内の各階床のエレベータ着床位置に遮蔽板が取付けられている。例えば２５０ｍｍの長さ寸法を有する前記遮蔽板は、その中心が乗かご着床位置の中心と一致するように取付けられ、エレベータは前記遮蔽検出器が前記遮蔽板を検出して１２５ｍｍ走行した位置に前記乗かごを停止するように制御される。しかしながら前記遮蔽板を検出してからの走行距離が１２５ｍｍを多少前後することがあり、かご床と乗場床との間に段差が生じることがある。   In general, an elevator is provided with a shielding plate detector on the passenger car side and a shielding plate at the elevator landing position on each floor in the hoistway. For example, the shielding plate having a length of 250 mm is attached so that the center thereof coincides with the center of the landing position of the car, and the elevator is located at a position where the shielding detector detects the shielding plate and travels 125 mm. Control is performed to stop the car. However, the traveling distance after detecting the shielding plate may be slightly longer than 125 mm, and a step may be generated between the car floor and the landing floor.

このため従来、エレベータの各種信号を監視するエレベータ異常検出装置を設け、遮蔽板検出から乗かご位置と停止時のかご位置をエレベータから取得して、乗かご着床時のかご床と乗場床との段差を算出し異常を検出するものが提案されている。このような異常検出装置では、例えば遮蔽板検出から乗かご停止までの走行距離が１２５ｍｍの場合にかご床と乗場床との段差が０ｍｍと判断される（例えば、特許文献１参照）。
特開平６−１００２５３号公報（段落番号０００７〜０００８） For this reason, conventionally, an elevator abnormality detection device that monitors various signals of the elevator is provided, and the car position and the car position at the time of stopping are obtained from the elevator from the shielding plate detection, and the car floor and the landing floor when the car is landing There has been proposed a method for detecting an abnormality by calculating a level difference between the two. In such an abnormality detection device, for example, when the travel distance from the shielding plate detection to the car stop is 125 mm, the step difference between the car floor and the landing floor is determined to be 0 mm (see, for example, Patent Document 1).

以下、本発明に係るエレベータ異常検出装置の実施形態を図に基づいて説明する。   Hereinafter, an embodiment of an elevator abnormality detection device according to the present invention will be described with reference to the drawings.

図１は本発明のエレベータ異常検出装置の実施形態を示す要部構成図、図２は補正データが登録される補正データテーブルを示す説明図、図３は補正データを算出する処理を示すフローチャート、図４は乗かご着床時の段差を算出する処理を示すフローチャートである。   FIG. 1 is a main part configuration diagram showing an embodiment of an elevator abnormality detection device of the present invention, FIG. 2 is an explanatory diagram showing a correction data table in which correction data is registered, and FIG. 3 is a flowchart showing a process for calculating correction data, FIG. 4 is a flowchart showing a process for calculating a level difference upon landing of the car.

建物に設置されたエレベータは図１に示すように、昇降路１内に図示しない係止部材を用いて最上階から最下階に渡って敷設されるガイドレール２と、このガイドレール２に沿って昇降する乗かご３と、昇降路１の上部に設置され、ロープ４の中間が巻き掛けられ乗かご３を昇降させる巻上機５と、各乗場階に対応してガイドレール２に設けられた遮蔽板６とを有している。   As shown in FIG. 1, an elevator installed in a building includes a guide rail 2 laid from the top floor to the bottom floor using a locking member (not shown) in the hoistway 1, and along the guide rail 2. The elevator 3 is installed at the top of the hoistway 1 and the hoisting machine 5 is installed on the guide rail 2 corresponding to each landing floor. And a shielding plate 6.

そして、本実施形態のエレベータ異常検出装置は、巻上機５と直結し巻上機５の回転軸の回転数を検出する回転数検出器７と、乗かご３に取付けられ、遮蔽板６の位置を検出し検出信号を制御盤９に出力する遮蔽板検出器８と、エレベータを制御する制御盤９に設けられ、停止目標階の停止位置と現在の乗かご３の走行位置とに基づいて乗かご３の走行指令を求める走行制御部１０と、制御盤９に設けられ、走行制御部１０よりエレベータの動作信号を常時読み取り，エレベータの異常を監視するエレベータ異常検出制御部１１と、エレベータ異常検出制御１１に接続可能であり、エレベータ異常検出制御部１１と各種データをやり取りするパソコン１２とを備えている。なお、乗かご着床時の段差の実測値を入力する入力手段は、例えばパソコン１２から成っている。   The elevator abnormality detection device according to the present embodiment is attached to the car 3 and a rotational speed detector 7 that is directly connected to the hoisting machine 5 and detects the rotational speed of the rotary shaft of the hoisting machine 5. A shield detector 8 that detects the position and outputs a detection signal to the control panel 9 and a control panel 9 that controls the elevator are provided on the basis of the stop position of the stop target floor and the current travel position of the car 3. A travel control unit 10 for obtaining a travel command for the car 3, an elevator abnormality detection control unit 11 that is provided on the control panel 9, constantly reads an elevator operation signal from the travel control unit 10 and monitors an elevator abnormality, and an elevator abnormality It can be connected to the detection control 11 and includes an elevator abnormality detection control unit 11 and a personal computer 12 that exchanges various data. In addition, the input means for inputting the actual measurement value of the level difference when the car is landed includes, for example, a personal computer 12.

また、前述の遮蔽板６は、例えば２５０ｍｍの長さ寸法を有しており、その中心が乗かご着床位置の中心と一致するように取付けられ、理論上、遮蔽板検出器８が遮蔽板６を検出して１２５ｍｍ走行して停止したときに、乗場階の床１３と乗かご３の床とが等しい高さとなる高さ位置に設けてある。さらに、前述のエレベータ異常検出制御部１１には、図２に示すように各階床の補正データを格納する補正データテーブル１４が備えられているとともに、このエレベータ異常検出制御部１１は図示しない電話回線に接続され、エレベータの異常検出に応じて管制センタに異常発報するようになっている。   The above-described shielding plate 6 has a length of, for example, 250 mm, and is attached so that the center thereof coincides with the center of the passenger car landing position. Theoretically, the shielding plate detector 8 is provided with the shielding plate. When 6 is detected and traveled 125 mm and stopped, the floor 13 of the landing floor and the floor of the car 3 are provided at a height position where they are equal. Further, as shown in FIG. 2, the above-mentioned elevator abnormality detection control unit 11 is provided with a correction data table 14 for storing correction data for each floor, and this elevator abnormality detection control unit 11 is provided with a telephone line (not shown). And an abnormality is reported to the control center in response to the detection of the abnormality of the elevator.

ここで図３を用いて補正データを算出する処理を説明する。まず、手順Ｓ１としてエレベータ異常検出制御部１１はパソコン１２を用いて入力された着床段差の実測データを受信したことを判断すると、手順Ｓ２として変数ｎに最下階データを設定し、次いで、手順３としてｎ階、すなわち最下階の実測データと算出した最下階の計算データの差異を最下階の補正データとして補正データテーブル１４へ登録する。この後、手順Ｓ４および手順Ｓ５を介して最下階から最上階に渡って同様の処理を行い全ての階床の補正データを算出および登録する。   Here, the process of calculating the correction data will be described with reference to FIG. First, in step S1, when it is determined that the elevator abnormality detection control unit 11 has received the actual measurement data of the landing step input using the personal computer 12, the lowest floor data is set in the variable n as step S2, and then In step 3, the difference between the measured data of the nth floor, that is, the lowest floor and the calculated data of the lowest floor is registered in the correction data table 14 as the correction data of the lowest floor. Thereafter, the same processing is performed from the lowest floor to the highest floor through steps S4 and S5, and correction data for all floors are calculated and registered.

次いで、図４を用いて乗かご３着床時の段差を算出する処理を説明する。エレベータ異常検出制御部１１は手順Ｓ１０で乗かご３の着床停止を検出すると、手順Ｓ１１として遮蔽板６検出時のかご位置を走行制御部１０より読み出すとともに、手順１２として乗かご停止時のかご位置を走行制御部１０より読み出し、かつ、手順Ｓ１３としてエレベータ異常検出制御部１１の補正データテーブルより停止階床の補正データを読み出す。この後、手順Ｓ１４でアップ走行かどうかを判断し、アップ走行の場合、手順Ｓ１５に示す算出式に手順Ｓ１１から手順Ｓ１３で読み出したそれぞれの値を当てはめ着床時の段差を算出するとともに、手順Ｓ１４でダウン走行であることを判断した場合、手順Ｓ１７に示す算出式に手順Ｓ１１から手順Ｓ１３で読み出したそれぞれの値を当てはめ着床時の段差を算出する。   Next, a process for calculating a level difference upon landing of the car 3 will be described with reference to FIG. When the elevator abnormality detection control unit 11 detects landing stop of the car 3 in step S10, the car position when the shielding plate 6 is detected is read from the travel control unit 10 as step S11, and the car when the car stops as step 12 The position is read from the traveling control unit 10, and the correction data of the stop floor is read from the correction data table of the elevator abnormality detection control unit 11 as step S13. Thereafter, in step S14, it is determined whether or not the vehicle is traveling up. In the case of up traveling, the steps read out in step S11 to step S13 are applied to the calculation formula shown in step S15 to calculate the step upon landing. When it is determined in S14 that the vehicle is traveling down, the values read in steps S11 to S13 are applied to the calculation formula shown in step S17 to calculate the step upon landing.

以上のように構成した本実施形態によれば、実際の着床段差の実測値と、エレベータ異常検出制御部１１が算出した計算値から遮蔽板６のずれを算出して補正データとして登録し、次回の計測から補正データを反映して着床の段差計測を行うため精度の高い計測が行うことができる。   According to the present embodiment configured as described above, the deviation of the shielding plate 6 is calculated and registered as correction data from the actual measurement value of the actual landing step and the calculated value calculated by the elevator abnormality detection control unit 11, Accurate measurement can be performed because the step difference measurement of the landing is performed by reflecting the correction data from the next measurement.
