Description

エレベータのドア開閉制御装置Elevator door opening and closing control device
　この発明は、かごの運行効率を向上させるエレベータのドア開閉制御装置に関するものである。 This invention relates to an elevator door opening / closing control device for improving the operation efficiency of a car.
　エレベータでは、乗客がかごに乗り降りし、乗り降りが完了してから、ドアが閉まり、かごが昇降を開始する。したがって、乗り降りを開始してから昇降が開始されるまでの間に待ち時間がある。この待ち時間が長いと、かごの運行効率が低下する要因となる。従来のエレベータシステムでは、このうち、かごへの乗客の乗り降りが完了してからドアが閉まり始めるまでの待ち時間を短縮することによって、かごの運行効率を高めている（例えば、特許文献１参照）。 In the elevator, passengers get on and off the car, and after getting on and off, the door closes and the car starts to move up and down. Therefore, there is a waiting time between the start of getting on and off and the start of lifting. If this waiting time is long, the operation efficiency of the car will be reduced. In the conventional elevator system, the operation efficiency of the car is increased by shortening the waiting time until the door starts to close after the passenger gets on and off the car (for example, see Patent Document 1). .
　特許文献１に記載された従来のエレベータでは、ドアセンサがかご内のドアに近づく乗客を検知している。また、この従来のエレベータでは、かごが開いてから閉まるまでに、３つの時間Ｔｄ、Ｔｃ、およびＴｅが管理されている。第１の時間Ｔｄは、ドアの開放時間として、乗客の乗場呼び、車椅子乗場呼び、およびかご呼びの各操作に応じて、それらすべての呼びを満了させるための時間である。第２の時間Ｔｃは、ドアセンサが乗客を検知しなくなった場合の待ち時間である。第３の時間Ｔｅは、ドアの開放時間として初期に設定された最小の時間である。 In the conventional elevator described in Patent Document 1, the door sensor detects a passenger approaching the door in the car. In this conventional elevator, three times Td, Tc, and Te are managed from when the car is opened until it is closed. The first time Td is a time for expiring all calls according to the passenger landing call, wheelchair landing call, and car call operation as the door opening time. The second time Tc is a waiting time when the door sensor stops detecting passengers. The third time Te is the minimum time initially set as the door opening time.
　特許文献１に記載された従来のエレベータは、ドアセンサが乗客を検知しなくなってから第２の時間Ｔｃが過ぎ、かつ、ドアが開いてから第３の時間Ｔｅが過ぎた時点で、第１の時間Ｔｄが満了するのを待たずに、ドアを閉め始めている。これにより、かごへの乗客の乗り降りが完了してからドアが閉まり始めるまでの待ち時間を短縮している。 The conventional elevator described in Patent Document 1 has the first time when the second time Tc has passed since the door sensor no longer detects passengers, and when the third time Te has passed since the door opened. The door is starting to close without waiting for the time Td to expire. This shortens the waiting time until the door starts to close after passengers get on and off the car.
特許第５７８５７６１号公報Japanese Patent No. 5785761
　特許文献１に記載された従来のエレベータでは、少なくとも、乗客は、ドアセンサが乗客を検知しなくなってから第２の時間Ｔｃおよびドアが開いてから第３の時間Ｔｅを待つ必要がある。そのため、特許文献１に記載された従来のエレベータでは、乗客には、不要な待ち時間が発生し、かごの運行効率は、その分だけ低下していた。 In the conventional elevator described in Patent Document 1, at least the passenger needs to wait for the second time Tc after the door sensor no longer detects the passenger and the third time Te after the door opens. Therefore, in the conventional elevator described in Patent Document 1, an unnecessary waiting time is generated for the passengers, and the operation efficiency of the car is reduced accordingly.
　この発明は、上記のような課題を解決するためになされたものであって、かごの運行効率をさらに向上させるエレベータのドア開閉制御装置を提供することを目的とするものである。 The present invention has been made to solve the above-described problems, and it is an object of the present invention to provide an elevator door open / close control device that further improves the operation efficiency of a car.
　この発明のエレベータのドア開閉制御装置は、エレベータのドアに設けられ、かごに乗り降りする乗客の方向を検出するドアセンサと、かごに設けられ、乗客の総重量を測定する秤と、ドアセンサによる検知結果、および秤による測定結果から、各階床での乗客の乗り降りの完了を判断し、ドアの開放時間を制御する制御部とを備えている。 The elevator door opening / closing control device according to the present invention includes a door sensor that is provided on an elevator door and detects a direction of a passenger getting on and off the car, a scale that is provided on the car and measures the total weight of the passenger, and a detection result by the door sensor. And a control unit that determines completion of passenger boarding / exiting on each floor from the measurement result of the scale and controls the opening time of the door.
　この発明によるエレベータのドア開閉制御装置によると、かごに乗降する乗客の方向性、およびかご内の乗客数に相当する値を検知し、乗降の完了後にドアを迅速に閉める構成を備えている。これにより、かごの運行効率をさらに向上させるエレベータのドア開閉制御装置を得ることができる。 The elevator door opening and closing control device according to the present invention has a configuration for detecting the directionality of passengers getting on and off the car and the value corresponding to the number of passengers in the car and quickly closing the doors after completion of the boarding and exiting. Thereby, the door opening / closing control apparatus of the elevator which further improves the operation efficiency of a car can be obtained.

　次に、エレベータのドア開閉制御装置１００の機能について、図２および図３を用いて説明する。
　ドアセンサ２０は、かご５に乗り降りする乗客の方向を検知する。かご側ドア１２の対向面１５および対向面１６の間に障害物がない場合、各乗場側センサセル２６および各かご側センサセル２７は、発光部２１が発する光を受ける。対向面１５および対向面１６の間に障害物が入った場合、各乗場側センサセル２６および各かご側センサセル２７は、部分的に発光部２１が発する光を受けなくなる。以下では、複数の乗場側センサセル２６のうちの一部が光を受けなくなった状態を、乗場側センサセル２６がオフになったと称する。同様に、複数のかご側センサセル２７のうちの一部が光を受けなくなった状態を、かご側センサセル２７がオフになったと称する。 Next, functions of the elevator door opening / closing control apparatus 100 will be described with reference to FIGS. 2 and 3.
The door sensor 20 detects the direction of passengers getting on and off the car 5. When there is no obstacle between the facing surface 15 and the facing surface 16 of the car-side door 12, each landing-side sensor cell 26 and each car-side sensor cell 27 receive light emitted from the light emitting unit 21. When an obstacle enters between the facing surface 15 and the facing surface 16, each landing-side sensor cell 26 and each car-side sensor cell 27 partially receive no light emitted from the light emitting unit 21. Hereinafter, a state in which some of the plurality of landing-side sensor cells 26 receive no light is referred to as the landing-side sensor cell 26 being turned off. Similarly, a state in which some of the plurality of car-side sensor cells 27 do not receive light is referred to as the car-side sensor cell 27 being turned off.
　通常の状態では、乗場側センサセル２６およびかご側センサセル２７は、オフにはなっていない。乗客が乗場からかご５に乗る場合、乗場側センサセル２６が先にオフになり、その後、かご側センサセル２７がオフになる。逆に、乗客がかご５から降りる場合、かご側センサセル２７が先にオフになり、その後、乗場側センサセル２６がオフになる。したがって、乗場側センサセル２６およびかご側センサセル２７がオフになる順序によって、乗客がかご５に乗ったという情報、または乗客がかご５から降りたという情報を得ることができる。このように、ドアセンサ２０は、かご５に乗り降りする乗客の方向を検知することができる。 In the normal state, the landing side sensor cell 26 and the car side sensor cell 27 are not turned off. When a passenger gets on the car 5 from the landing, the landing-side sensor cell 26 is turned off first, and then the car-side sensor cell 27 is turned off. Conversely, when the passenger gets out of the car 5, the car-side sensor cell 27 is turned off first, and then the landing-side sensor cell 26 is turned off. Therefore, the information that the passenger got on the car 5 or the information that the passenger got out of the car 5 can be obtained according to the order in which the hall-side sensor cell 26 and the car-side sensor cell 27 are turned off. Thus, the door sensor 20 can detect the direction of passengers getting on and off the car 5.
　秤３０は、乗客の総重量を測定する。乗客がかご５に乗り降りすると、秤３０が示す重量は変動する。このように、秤３０は、かご５に乗り降りする乗客の数に相当する重量を測定することができる。 The scale 30 measures the total weight of passengers. When a passenger gets on and off the car 5, the weight indicated by the scale 30 changes. Thus, the scale 30 can measure the weight corresponding to the number of passengers getting on and off the car 5.
　制御部４０は、ドアセンサ２０による検知結果、および秤３０による測定結果から、各階床での乗客の乗り降りの完了を判断することができる。すなわち、ドアセンサ２０が乗客を検知しなくなり、秤３０による重量の変動が許容値以内に収まった場合に、制御部４０は、かご５への乗客の乗り降りが完了したと判断することができる。この場合、制御部４０は、乗場側ドア１１およびかご側ドア１２をただちに閉め、かご５を移動させることができる。すなわち、制御部４０は、かご５への乗客の乗り降りの完了を判断し、エレベータのドアの開放時間を制御する。これにより、待ち時間が少なくなり、かご５の運行効率をさらに向上させるエレベータのドア開閉制御装置を得ることができる。 The control unit 40 can determine the completion of passenger boarding / exiting on each floor from the detection result by the door sensor 20 and the measurement result by the scale 30. That is, when the door sensor 20 does not detect a passenger and the variation in weight by the balance 30 falls within an allowable value, the control unit 40 can determine that the passenger has got on and off the car 5. In this case, the control unit 40 can immediately close the landing-side door 11 and the car-side door 12 and move the car 5. That is, the control unit 40 determines completion of passenger getting on and off the car 5 and controls the opening time of the elevator door. Thereby, waiting time decreases and the door opening / closing control apparatus of the elevator which further improves the operation efficiency of the car 5 can be obtained.
　制御部４０は、ビルマネジメントシステム２００に、各階床での乗客の乗り降りの完了状態を送信する。これにより、ビルマネジメントにおける動態管理が効率化され、ビル管理の効率が向上する。この例では、制御部４０は、信号線４１によって、各階床での乗客の乗り降りの完了状態をビルマネジメントシステム２００に送信している。制御部４０は、無線方式によって、各階床での乗客の乗り降りの完了状態をビルマネジメントシステム２００に送信してもよい。 The control unit 40 transmits to the building management system 200 the completion status of passengers getting on and off at each floor. Thereby, the dynamic management in building management becomes efficient, and the efficiency of building management improves. In this example, the control unit 40 transmits, to the building management system 200, the completion state of passengers getting on and off at each floor via the signal line 41. The control part 40 may transmit the completion state of passenger getting on and off at each floor to the building management system 200 by a wireless method.
　この実施の形態１のエレベータのドア開閉制御装置によれば、ドアセンサによる検知結果、および秤による測定結果から、制御部がかごへの乗客の乗り降りが完了したと判断できる場合、制御部がただちにドアを閉め、かごを移動させることができる構成を有している。その結果、かごの運行効率をさらに向上させるエレベータのドア開閉制御装置を得ることができる。 According to the elevator door opening and closing control device of the first embodiment, when the control unit can determine that the passenger has got on and off the car from the detection result by the door sensor and the measurement result by the scale, the control unit immediately opens the door. Is closed and the car can be moved. As a result, it is possible to obtain an elevator door open / close control device that further improves the operation efficiency of the car.
　また、この実施の形態１のエレベータのドア開閉制御装置によれば、ドアセンサは、ドアの厚さ方向に沿って取り付けられた複数のセンサセルを有している。その結果、ドアセンサは、かごに乗り降りする乗客の方向を検知することができる。また、センサセルをかご側ドアに取り付けることにより、センサ実装の省スペース化を図ることができる。 In addition, according to the elevator door opening / closing control apparatus of the first embodiment, the door sensor has a plurality of sensor cells attached along the thickness direction of the door. As a result, the door sensor can detect the direction of passengers getting on and off the car. Further, by mounting the sensor cell to the car side door, it is possible to save the space for mounting the sensor.
　また、この実施の形態１のエレベータのドア開閉制御装置によれば、エレベータを管理するビルマネジメントシステムに、各階床での乗客の乗り降りの完了状態を送信する構成を有している。その結果、ビルマネジメントにおける動態管理が効率化され、ビル管理の効率を向上させることができる。 Further, according to the elevator door opening / closing control apparatus of the first embodiment, the building management system for managing the elevator has a configuration for transmitting the completion state of passengers getting on and off at each floor. As a result, the dynamic management in building management is made efficient, and the efficiency of building management can be improved.
　なお、秤３０による測定結果により、かご５内に乗客がいないと制御部４０が判断できる場合には、かご５の昇降速度を高めることができる。これにより、かごの運行効率をさらに高めることができる。 In addition, when the control part 40 can judge that there is no passenger in the cage | basket | car 5 by the measurement result by the balance 30, the raising / lowering speed of the cage | basket | car 5 can be raised. Thereby, the operation efficiency of the car can be further increased.
　なお、各乗場側センサセル２６間の上下方向のピッチは、一定でなくてもよい。同様に、各かご側センサセル２７間の上下方向のピッチは、一定でなくてもよい。また、各乗場側センサセル２６と各かご側センサセル２７との間隔は、一定でなくてもよい。 Note that the vertical pitch between the landing-side sensor cells 26 may not be constant. Similarly, the vertical pitch between the car-side sensor cells 27 may not be constant. Further, the interval between each landing-side sensor cell 26 and each car-side sensor cell 27 may not be constant.
　また、ドアセンサ２０は、かご側ドア１２の厚さ方向に沿って、乗場側センサセル２６およびかご側センサセル２７の位置に合わせて、第３のセンサセルを有してもよい。第３のセンサセルは、乗場側センサセル２６より乗場側に設けられてもよい。また、第３のセンサセルは、かご側センサセル２７よりかご側に設けられてもよい。さらに、第３のセンサセルは、乗場側センサセル２６およびかご側センサセル２７の間に設けられてもよい。ドアセンサ２０が第３のセンサセルを有する場合、かごに乗り降りする乗客の方向を、さらに正確に検知することができる。 Further, the door sensor 20 may have a third sensor cell in accordance with the position of the landing side sensor cell 26 and the car side sensor cell 27 along the thickness direction of the car side door 12. The third sensor cell may be provided closer to the landing side than the landing side sensor cell 26. Further, the third sensor cell may be provided on the car side from the car side sensor cell 27. Further, the third sensor cell may be provided between the landing side sensor cell 26 and the car side sensor cell 27. When the door sensor 20 has a third sensor cell, the direction of passengers getting on and off the car can be detected more accurately.
