Description

この発明は、エレベータの乗場装置、特に電源電圧の変動に対して階床乗場における乗場ボタンの輝度を所定値に保持することができるエレベータの乗場装置及びその乗場ボタンの点灯方法に関するものである。   The present invention relates to an elevator landing device, and more particularly to an elevator landing device capable of maintaining the brightness of a landing button at a floor landing at a predetermined value against fluctuations in power supply voltage, and a lighting method for the landing button.

従来のエレベータの乗場装置は、各階床ごとに設けられた複数の階床乗場装置が１つの電源装置から電源の供給を受けるようにされ、しかも電源ケーブルは電源装置から各階床乗場装置へ個別に配線するのではなく、昇降路内に幹線を敷設し、上記幹線から枝線を出して各階に設置された階床乗場装置に配線するようにされていた。（例えば特許文献１参照）。   In a conventional elevator landing device, a plurality of floor landing devices provided for each floor are supplied with power from one power supply device, and a power cable is individually supplied from the power supply device to each floor landing device. Instead of wiring, a trunk line was laid in the hoistway, and a branch line was drawn from the trunk line and wired to a floor landing device installed on each floor. (For example, refer to Patent Document 1).

特開２００３−３３５４７２号公報JP 2003-335472 A

従来のエレベータの乗場装置は上記のように構成されていたため、エレベータの階間によって電源ケーブルの配線長が決まり、電源装置付近の電源ケーブルには接続された全階床乗場装置の消費電流の合計が流れるようになっていた。   Since the conventional elevator landing device is configured as described above, the wiring length of the power cable is determined by the elevator floor, and the total current consumption of all floor landing devices connected to the power cable near the power supply device Began to flow.

従って接続される階床乗場装置の数が増えるほど消費電流が増え、電源ケーブルの長さが長くなることから、電源ケーブルでの電圧低下が大きくなり、階床乗場装置での電源電圧、即ち入力電圧が低くなっていた。   Therefore, as the number of floor landing devices connected increases, the current consumption increases and the length of the power cable increases, so the voltage drop at the power cable increases, and the power supply voltage at the floor landing device, that is, the input The voltage was low.

階床乗場装置に設けられる乗場ボタンなどは上記電源電圧によって照光部分を光らせる構成となっていたため、入力電源電圧が低くなり過ぎると照光部分が暗くなるという問題点があった。   Since the landing buttons and the like provided on the floor landing device are configured to illuminate the illuminated portion with the power supply voltage, there is a problem that the illuminated portion becomes dark when the input power supply voltage becomes too low.

このため、１つの電源装置に接続する階床乗場装置の数と電源ケーブルの配線長を一定範囲内に制限する必要があり、電源装置の配置を複雑にしていた。
この場合、電源ケーブルを太くすることで抵抗値を下げ、配線での電圧低下を抑えることはできるが、配線が大きくなり、高コスト化を招くという問題点があった。 For this reason, it is necessary to limit the number of floor landing devices connected to one power supply device and the length of the power cable within a certain range, and the arrangement of the power supply devices is complicated.
In this case, although the resistance value can be lowered by making the power cable thicker and the voltage drop in the wiring can be suppressed, there is a problem that the wiring becomes larger and the cost is increased.

また、定電流回路を用いれば、電源電圧に係わらず乗場ボタンの照光部分の輝度を一定に保つことが出来るが、定電流回路で消費＝発熱される電力が大きくなり過ぎることから、階床乗場装置の大型化を招くという問題点があった。   In addition, if the constant current circuit is used, the brightness of the illuminated part of the hall button can be kept constant regardless of the power supply voltage, but the power consumed by the constant current circuit = the generated heat becomes too large. There was a problem that the size of the apparatus was increased.

更に、階床乗場装置内のマイコンに供給されるマイコン用電圧は、レギュレータを介することによって電源電圧に関係なく一定とされているが、乗場ボタンに必要な電源電圧はマイコン用電圧より高い電圧が一般的に用いられているため、マイコン用電圧で点灯するようにすれば、従来の高い電圧で使用していた乗場ボタンとの互換性がなくなるという問題点もある。   Furthermore, the microcomputer voltage supplied to the microcomputer in the floor hall device is constant regardless of the power supply voltage through the regulator, but the power supply voltage required for the landing button is higher than the microcomputer voltage. Since it is generally used, if it is turned on with a voltage for a microcomputer, there is a problem that compatibility with a hall button used at a conventional high voltage is lost.

更にまた、乗場ボタン専用に電圧の高い別のレギュレータを設置して電源電圧を一定に保持することも考えられるが、この場合には、コストアップとサイズアップになるという問題点があった。   Furthermore, it is conceivable to install another regulator with a high voltage exclusively for the hall button to keep the power supply voltage constant. However, in this case, there is a problem that the cost increases and the size increases.

この発明は上記のような問題点を解消するためになされたもので、１つの電源装置から複数の階床乗場に電源を供給し、電圧低下が大きくなっても乗場ボタンの照光部分の輝度を所定値に保持することが出来るエレベータの乗場装置及びその乗場ボタンの点灯方法を提供することを目的とする。   The present invention has been made to solve the above-described problems. Power is supplied from one power supply device to a plurality of floor halls, and the brightness of the illuminated portion of the hall button can be increased even when the voltage drop increases. It is an object of the present invention to provide an elevator hall device that can be maintained at a predetermined value and a lighting method for the hall button.

この発明に係るエレベータの乗場装置は、各階の階床乗場に設けられ、インジケータに階床表示を行なわせると共に、乗場呼び時に乗場ボタンを点灯させる複数の階床乗場装置が１つの電源装置から電源の供給を受けるエレベータの乗場装置において、上記階床乗場装置を、上記電源装置からの電源電圧を測定する電圧測定回路と、上記乗場ボタンの点灯時に上記乗場ボタンを点滅させ、その点滅周期中の点灯時間または点灯率を制御し得るようにしたボタン点灯回路と、上記電源電圧の変動に対して上記乗場ボタンの輝度を所定値に保持するため、上記電源電圧と上記乗場ボタンの点滅周期に対する点灯時間または点灯率との関係を示すデータを記憶させた点灯率データベースと、上記電圧測定回路からの電圧に応じた点灯時間または点灯率を上記点灯率データベースから読み出し、上記ボタン点灯回路に点滅状態を指示するマイコンとから構成したものである。   The elevator hall device according to the present invention is provided at the floor hall of each floor, and a plurality of floor hall devices that cause the indicator to display a floor and turn on the hall button when calling to the hall are powered from one power supply device. In the elevator landing device that receives the supply of the above, the floor landing device includes a voltage measuring circuit that measures a power supply voltage from the power supply device, and the landing button blinks when the landing button is lit, A button lighting circuit capable of controlling the lighting time or lighting rate, and lighting for the blinking cycle of the power supply voltage and the landing button in order to maintain the brightness of the landing button at a predetermined value with respect to the fluctuation of the power supply voltage A lighting rate database that stores data indicating the relationship with time or lighting rate, and lighting time or lighting according to the voltage from the voltage measurement circuit Reading from the lighting rate database, which is constituted from a microcomputer to instruct the flashing state to the button lighting circuit.

この発明に係るエレベータの乗場装置は上記のように構成されているため、各階床乗場装置の電源電圧の低下が大きくなっても乗場ボタンの照光部分の輝度を所定値に保持することができ、１つの電源装置に接続することが出来る階床乗場装置の数を増やすことができる。   Since the elevator hall device according to the present invention is configured as described above, the luminance of the illuminated portion of the hall button can be maintained at a predetermined value even when the power supply voltage of each floor hall device decreases greatly. The number of floor landing devices that can be connected to one power supply device can be increased.

また、エレベータの大半を占める階床数の少ないエレベータに対して電源装置を１つにすることができるため、低コスト化を図ることができると共に、電源装置の配置を容易にすることができる。   In addition, since one power supply device can be provided for an elevator that occupies most of the elevators and has a small number of floors, the cost can be reduced and the arrangement of the power supply devices can be facilitated.

実施の形態１．
以下、この発明の実施の形態１を図にもとづいて説明する。図１は、実施の形態１の概略構成を示すブロック図である。 Embodiment 1 FIG.
Embodiment 1 of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of the first embodiment.

この図は、エレベータの運転を制御するエレベータ制御盤１と、各階床に設けられる階床乗場装置２−１、２−２、２−(n1+1)と、それらに電源電圧を供給する１つの電源装置１２とを示している。なお、階床乗場装置は、そのうちの１つである符号２−１で示すものについてのみ詳細構成を示しているが、他の階床乗場装置についても同様な構成とされているものである。   This figure shows an elevator control panel 1 for controlling the operation of the elevator, floor landing devices 2-1 2-2, 2- (n1 + 1) provided on each floor, and a power supply voltage 1 supplied to them. One power supply device 12 is shown. In addition, although the floor landing apparatus has shown the detailed structure only about what is shown with the code | symbol 2-1, which is one of them, it is set as the same structure also about another floor landing apparatus.

階床乗場装置２−１は、電源装置１２から電源ケーブル１３で電源電圧Vinが供給され、レギュレータ１０で定電圧のマイコン用電圧V1に変換した後、マイコン５とインジ駆動回路４に供給され、インジ駆動回路４はマイコン５からの指令を受けてドット式のインジケータ３を点灯し、階床表示を行なうようにされている。   The floor landing device 2-1 is supplied with the power supply voltage Vin from the power supply device 12 through the power supply cable 13, converted into the constant voltage V1 for the microcomputer with the regulator 10, and then supplied to the microcomputer 5 and the drive circuit 4. Inge drive circuit 4 receives a command from microcomputer 5 and lights up dot type indicator 3 to perform floor display.

また、電源電圧Vinはボタン点灯回路６に与えられ、マイコン５からの指令を受けて乗場ボタン１１−１を点灯するようにされている。
この乗場ボタン１１−１は点灯指令によって連続点灯するのではなく、後述するように、点滅する形で点灯するようにされている。以下、図２にもとづいて従来の点灯と比較しながら説明する。 The power supply voltage Vin is applied to the button lighting circuit 6 so that the hall button 11-1 is lit in response to a command from the microcomputer 5.
The hall button 11-1 is not lit continuously by a lighting command, but is lit in a blinking manner as will be described later. Hereinafter, description will be made based on FIG. 2 while comparing with conventional lighting.

図２において、（ａ）はエレベータ制御盤１から通信ケーブル１４及び通信回路７を経てマイコン５に与えられる点灯指令信号（ｂ）は点灯指令があった場合の従来の乗場ボタンの点灯状態を示し、（ｃ）は同じくこの発明の乗場ボタン１１−１の点灯状態を示す。   In FIG. 2, (a) is a lighting command signal (b) given from the elevator control panel 1 to the microcomputer 5 via the communication cable 14 and the communication circuit 7, and shows the lighting state of the conventional hall button when there is a lighting command. (C) shows the lighting state of the hall button 11-1 of the present invention.

即ち、エレベータ制御盤１からの点灯指令に対し、従来は乗場ボタンが連続点灯していたため、電源電圧が低下し過ぎると暗くなっていたが、この発明では（ｃ）に示すように、点灯と消灯を繰り返す点滅状態が継続するようになっている。   That is, in response to the lighting command from the elevator control panel 1, the hall button has been continuously lit, so it was dark when the power supply voltage was too low. However, in the present invention, as shown in FIG. The blinking state that repeats turning off continues.

この点滅周期Tを点滅が分からなくなる程度に早くすると、点灯時間Tonが長いほど明るく、点灯時間Tonが短いほど暗く見える。この特性を利用することで、電源電圧Vinが大幅に低下しても乗場ボタンの輝度を所定値に保持することができるものである。   When the blinking period T is shortened to such an extent that blinking is not understood, the longer the lighting time Ton, the brighter the light, and the shorter the lighting time Ton, the darker the light. By utilizing this characteristic, the brightness of the hall button can be maintained at a predetermined value even when the power supply voltage Vin is significantly reduced.

一方、階床乗場装置２−１の電源電圧Vinは電圧測定回路９によって電圧値が測定され、その低下状態をも含めてマイコン５に伝達される。また、点灯率データベース８には、電源電圧Vinの変動に対して乗場ボタン１１−１の輝度を所定値に保持するための、乗場ボタンの点滅周期Tに対する点灯時間Tonと電源電圧の変動との関係を示すデータが記憶されており、マイコン５から電源電圧に対応した点灯時間Tonが読み出されるようになっている。   On the other hand, the voltage value of the power supply voltage Vin of the floor hall device 2-1 is measured by the voltage measuring circuit 9 and transmitted to the microcomputer 5 including the lowered state. Further, the lighting rate database 8 includes a lighting time Ton with respect to the blinking period T of the hall button and a fluctuation of the power supply voltage in order to keep the luminance of the hall button 11-1 at a predetermined value with respect to the fluctuation of the power supply voltage Vin. Data indicating the relationship is stored, and the lighting time Ton corresponding to the power supply voltage is read from the microcomputer 5.

なお、図１では、マイコン５と電圧測定回路９と点灯率データベース８とを別の装置として示しているが、電圧測定回路９はマイコン５に内蔵されたＡ−Ｄコンバータを用いて構成してもよいし、点灯率データベース８はマイコン５に内蔵されたＲＯＭあるいはＲＡＭを用いて構成してもよい。また、点灯率データベース８に電圧に対応して記憶されている図２の点滅周期に対する点灯時間Tonは、点滅周期Tに対する点灯率として設定してもよい。   In FIG. 1, the microcomputer 5, the voltage measurement circuit 9, and the lighting rate database 8 are shown as separate devices. However, the voltage measurement circuit 9 is configured by using an A / D converter built in the microcomputer 5. Alternatively, the lighting rate database 8 may be configured using a ROM or a RAM built in the microcomputer 5. Further, the lighting time Ton for the blinking cycle of FIG. 2 stored in the lighting rate database 8 corresponding to the voltage may be set as the lighting rate for the blinking cycle T.

次に、エレベータ制御盤１からの点灯指令があった場合の階床乗場装置２−１の動作について図３のフローチャートを用いて説明する。   Next, the operation of the floor hall device 2-1 when there is a lighting command from the elevator control panel 1 will be described using the flowchart of FIG.

ステップＳ１で動作を開始し、ステップＳ２で乗場ボタン点灯指令が点灯を指示しているかどうかを確認する。点灯を指示している場合には、ステップＳ３でマイコン５が電圧測定回路９から電源電圧Vinを読み取る。ステップＳ２で点灯が指示されていない場合には、後述するステップＳ７に進む。   The operation is started in step S1, and it is confirmed in step S2 whether the hall button lighting command instructs lighting. When lighting is instructed, the microcomputer 5 reads the power supply voltage Vin from the voltage measurement circuit 9 in step S3. If lighting is not instructed in step S2, the process proceeds to step S7 described later.

次に、ステップＳ４で点灯率データベース８から読み出した電源電圧Vinに対する乗場ボタンの輝度を所定値に保持するための点灯時間Tonを読み込む。
その後、ステップＳ５でマイコン５からの指令によりボタン点灯回路６をONにして乗場ボタン１１−１を点灯する。 Next, the lighting time Ton for holding the brightness of the hall button with respect to the power supply voltage Vin read from the lighting rate database 8 in step S4 is read.
Thereafter, in step S5, the button lighting circuit 6 is turned on by a command from the microcomputer 5 to light the hall button 11-1.

点灯開始後、ステップＳ６で点灯時間Tonが経過したかどうかを確認する。
経過している場合には、ステップＳ７で乗場ボタン１１−１を消灯し、経過していない場合には、ステップＳ５に戻る。 After starting lighting, it is checked in step S6 whether the lighting time Ton has elapsed.
If it has elapsed, the hall button 11-1 is turned off in step S7, and if it has not elapsed, the process returns to step S5.

続いて、ステップＳ８で点灯周期Tが経過したかどうかを確認する。
経過している場合には、ステップＳ２に戻り、経過していない場合には、ステップＳ７に戻る。 Subsequently, in step S8, it is confirmed whether or not the lighting cycle T has elapsed.
If it has elapsed, the process returns to step S2, and if it has not elapsed, the process returns to step S7.

インジケータ３は階床乗場装置２−１に内蔵されているため、従来との互換性を考える必要がない。そこでインジ駆動回路４はレギュレータ１０から出力されるマイコン用電圧V1でインジケータ３を点灯し、電源電圧Vinに関係なく一定輝度で点灯することができる。もちろん、乗場ボタン１１−１と同様に電源電圧Vinに応じて点灯率を調整する方法でも一定輝度にすることができるのは言うまでもない。   Since the indicator 3 is built in the floor landing device 2-1, it is not necessary to consider compatibility with the conventional one. Therefore, the drive circuit 4 can light the indicator 3 with the microcomputer voltage V1 output from the regulator 10, and can light with a constant luminance regardless of the power supply voltage Vin. Of course, it is needless to say that a constant luminance can be achieved by a method of adjusting the lighting rate in accordance with the power supply voltage Vin as in the case of the hall button 11-1.

実施の形態１は以上のように構成されているため、階床乗場装置２−１は正常に動作可能な電源電圧Vinの範囲を従来より広げることができ、１つの電源装置１２に接続できる階床乗場装置２−１の数と配線長の制限を従来より広げることができる。
つまり、階床数の低いエレベータでは電源装置１２を１つにすることができ、低コスト化と電源装置１２の配置容易化を併せて図ることができる。 Since the first embodiment is configured as described above, the floor landing device 2-1 can expand the range of the power supply voltage Vin that can be normally operated and can be connected to one power supply device 12. Limits on the number of floor landing devices 2-1 and the wiring length can be increased as compared with the conventional one.
That is, in an elevator with a low number of floors, the number of power supply devices 12 can be reduced to one, and it is possible to reduce the cost and facilitate the arrangement of the power supply devices 12.
