Description

この発明は、エレベータ騒音を低減するためのエレベータの制御装置に関するものである。 The present invention relates to an elevator control device for reducing elevator noise.

通常、エレベータの速度は時間帯に拘わらず常に一定で走行している。しかし、周囲が静かな深夜運転時などで機械室や昇降路に近い住人からモータのうなり音やエレベータの走行時騒音がうるさいというような問題が起きる場合があった。その対応策としては、モータのキャリア周波数を下げたり、騒音を発生させている機器を新しいものに取り替えたりするなどの対策が必要であった。 Normally, the elevator speed is always constant regardless of the time zone. However, there are cases in which the noise of the motor and the noise of the elevator running from a resident near the machine room and the hoistway may occur during midnight operation where the surroundings are quiet. As countermeasures, measures such as lowering the carrier frequency of the motor or replacing the noise generating device with a new one were necessary.

また、従来、複数のエレベータかご毎にかごの走行によって建物内の居室に及ぶ騒音値を予測して互いに比較し、騒音値が最も小さいエレベータかごを割り当てるようにすることで、建物内の居室に及ぶ騒音を低減するエレベータの運行管理装置があった（例えば、特許文献１参照）。 In addition, conventionally, by predicting the noise value that reaches the room in the building by running the car for each of the elevator cars and comparing them, the elevator car with the lowest noise value is assigned to the room in the building. There has been an elevator operation management device that reduces the noise level (see, for example, Patent Document 1).

この発明は上記のような問題点を解決するためになされたもので、モータのキャリア周波数を下げたり、騒音を発生させている機器を新しいものに取り替えたりする必要なく、周囲が静かなときにエレベータ騒音を低減することができるエレベータの制御装置を得ることを目的とする。 The present invention has been made to solve the above-mentioned problems, and it is not necessary to lower the carrier frequency of the motor or to replace a noise generating device with a new one, and when the surroundings are quiet.

実施の形態１．
図１は、この発明の実施の形態１に係るエレベータの制御装置の全体構成を示すブロック図である。図１に示されるように、モータ１によって駆動される巻上機２の綱車にはメインロープ３が巻き掛けられ、メインロープ３の両端にはエレベータのかご４と釣合おもり５が取り付けられている。また、かご４には、かご４内の負荷（例えば乗客の重さ）を検出する秤装置６が設けられ、かご４内の負荷を制御盤内の記憶装置１０に出力する。また、モータ１は電力変換器７から駆動電源が供給される。 Embodiment 1 FIG.
1 is a block diagram showing an overall configuration of an elevator control apparatus according to Embodiment 1 of the present invention. As shown in FIG. 1, a main rope 3 is wound around a sheave of a hoist 2 driven by a motor 1, and an elevator car 4 and a counterweight 5 are attached to both ends of the main rope 3. ing. Further, the car 4 is provided with a scale device 6 that detects a load (for example, the weight of a passenger) in the car 4, and outputs the load in the car 4 to the storage device 10 in the control panel. The motor 1 is supplied with driving power from the power converter 7.

また、機械室や各階の乗場には騒音センサ８が取り付けられ、制御盤内の記憶装置１０に騒音の大きさを出力する。記憶装置１０は、騒音センサ８と秤装置６とからの検出値に基づいて昇降方向に応じたかご内負荷と発生騒音レベルとの関係を予め記憶する。さらに、昇降効率のいらない走行条件か否かを判定し、昇降効率のいらない走行条件である場合に、秤装置６からのかご内負荷の検出値に応じて予想される発生騒音レベルを記憶装置１０から読み出して基準騒音レベルと比較し、発生騒音レベルが基準騒音レベルより大きいときにかごの走行する一定速度を減速させるように制御する制御盤内の速度制御装置１１を備えており、この速度制御装置１１からの速度指令が電力変換器７に与えられてモータ１が速度制御される。なお、速度情報９は、エレベータの速度を一定速制御する際の速度情報である。また、ここで、昇降効率のいらない走行条件とは、現在の時刻が深夜であり、他階の乗場呼びがない場合等の昇降効率のいらない走行条件を示す。 Further, a noise sensor 8 is attached to the machine room and the landings on each floor, and outputs the magnitude of noise to the storage device 10 in the control panel. The storage device 10 stores in advance the relationship between the car load and the generated noise level in accordance with the ascending / descending direction based on the detection values from the noise sensor 8 and the scale device 6. Further, it is determined whether or not the traveling condition does not require the lifting efficiency, and when it is the traveling condition that does not require the lifting efficiency, the generated noise level that is expected according to the detected value of the load in the car from the scale device 6 is stored in the storage device 10. Is compared with a reference noise level, and a speed control device 11 in a control panel is provided to control to decelerate a constant speed at which the car travels when the generated noise level is greater than the reference noise level. A speed command from the device 11 is given to the power converter 7 to control the speed of the motor 1. The speed information 9 is speed information when the elevator speed is controlled at a constant speed. Here, the traveling condition that does not require lifting efficiency refers to a traveling condition that does not require lifting efficiency, such as when the current time is midnight and there is no hall call on another floor.

次に、上記構成に係るエレベータの制御装置の動作について、主に速度制御装置１１の動作内容を示す図２に示すフローチャートを参照して説明する。
本発明において、まず、速度制御装置１１は、昇降効率のいらない走行条件かを決定する。すなわち、現在の時刻が深夜であり、かつ他階の乗場呼びがない場合に、走行速度を変更させることができる走行条件であると決定する（ステップＳ２１〜Ｓ２３）。 Next, the operation of the elevator control device according to the above configuration will be described with reference to a flowchart shown in FIG.
In the present invention, first, the speed control device 11 determines whether the traveling condition does not require lifting efficiency. That is, when the current time is midnight and there is no hall call on another floor, it is determined that the traveling condition can change the traveling speed (steps S21 to S23).

このとき、秤装置６とからのかご負荷検出値は記憶装置１０と速度制御装置１１に出力されており（ステップＳ２４）、速度を変更させることができる条件ならば、速度制御装置１１は、図３で示すように、騒音センサ８と秤装置６とからの検出値に基づいて昇降方向（上昇方向：ＵＰ、下降方向：ＤＮ）に応じたかご内負荷と発生騒音レベルとの関係を予め記憶した記憶装置１０の記憶データを参照して、秤装置６からのかご内負荷の検出値に応じて予想される発生騒音レベルを読み出し（ステップＳ２５）、発生騒音レベルを基準騒音レベルと比較し（ステップＳ２６）、図４に示すように、発生騒音レベルが基準騒音レベル以上であれば、一定速度を減速させる。その減速させる速度は、発生騒音が基準騒音レベルを下回るように減速する（ステップＳ２７，Ｓ２８）。なお、ステップＳ２２，Ｓ２３，Ｓ２７において、ＮＯと判定された場合は通常走行となる。 At this time, the car load detection value from the scale device 6 is output to the storage device 10 and the speed control device 11 (step S24), and if the speed can be changed, the speed control device 11 3, the relationship between the load in the car and the generated noise level in accordance with the ascending / descending direction (upward direction: UP, downward direction: DN) based on the detection values from the noise sensor 8 and the scale device 6 is stored in advance. With reference to the stored data of the storage device 10, the generated noise level expected according to the detected value of the load in the car from the scale device 6 is read (step S25), and the generated noise level is compared with the reference noise level ( Step S26), as shown in FIG. 4, if the generated noise level is equal to or higher than the reference noise level, the constant speed is reduced. The deceleration speed is reduced so that the generated noise falls below the reference noise level (steps S27 and S28). In addition, in step S22, S23, S27, when it determines with NO, it will be a normal driving | running | working.

従って、前述した実施の形態によれば、深夜などのあまり昇降効率のいらない時間帯や他の階床での呼びの有無などによって、騒音が大きくなる場合のエレベータ一定速を通常より減速させるようにすることで、モータの回転数が減少し、モータのうなり音やレールから発生するエレベータの通過音を小さくすることができ、居室の快適性が確保される。 Therefore, according to the above-described embodiment, the constant speed of the elevator when the noise becomes louder than usual due to a time zone that does not require much lifting efficiency such as midnight or the presence or absence of a call on other floors, is decelerated from normal. By doing so, the number of rotations of the motor is reduced, and the noise of the motor and the passing sound of the elevator generated from the rail can be reduced, and the comfort of the room is ensured.
