以下、本発明の乗客コンベアに係る実施の形態を図に基づいて説明する。   Hereinafter, an embodiment according to a passenger conveyor of the present invention will be described with reference to the drawings.

図１は、本発明の乗客コンベアの一実施形態を示す概略構成図である。   FIG. 1 is a schematic configuration diagram showing an embodiment of a passenger conveyor of the present invention.

本実施形態の乗客コンベアは、図１に示すように、乗客コンベア乗降部デッキボード部にレーザスキャンセンサ１ａ、１ｂを設けている。これらレーザスキャンセンサ１ａ、１ｂを信号処理装置２に接続し、信号処理装置２の内部にあるシリアル通信送受信部５にてレーザスキャンセンサ１ａ、１ｂからのデータを受信し、ＣＰＵ３にてデータを処理して処理結果をインターフェース部６から出力する。メモリ４は、前記ＣＰＵ３での処理プログラム等を記憶し、また、えられたデータを記録することができる。信号処理装置２の出力は、乗客コンベア制御装置７へ送られ、乗客コンベア制御装置７は、状態に応じて、音声合成装置１１を介して、乗降部付近に設置したスピーカ１２ａ，１２ｂより乗客コンベア利用客に対して注意喚起放送を行う。同時に、インバータ装置８の出力周波数を低下させて、交流電動機９の回転速度を低下させて、乗客コンベアの運転速度を低下させる。さらに、遠隔監視装置１０を介して、保守管理会社管理装置に対して乗降部に立ち止まり、滞留、混雑状態が発生していることを発報して、乗客コンベア管理状態の確認を促すことができる。   As shown in FIG. 1, the passenger conveyor of the present embodiment is provided with laser scan sensors 1 a and 1 b on the passenger conveyor boarding / alighting part deck board part. These laser scan sensors 1a and 1b are connected to the signal processing device 2, the serial communication transmitting / receiving unit 5 inside the signal processing device 2 receives the data from the laser scan sensors 1a and 1b, and the CPU 3 processes the data. Then, the processing result is output from the interface unit 6. The memory 4 can store a processing program or the like in the CPU 3 and can record the obtained data. The output of the signal processing device 2 is sent to the passenger conveyor control device 7, and the passenger conveyor control device 7 passes through the speech synthesizer 11 depending on the state, and the passenger conveyor from the speakers 12 a and 12 b installed near the boarding / exiting section. Broadcast alerts to users. At the same time, the output frequency of the inverter device 8 is decreased, the rotational speed of the AC motor 9 is decreased, and the operation speed of the passenger conveyor is decreased. Furthermore, it is possible to stop at the boarding / exiting section with respect to the maintenance management company management device via the remote monitoring device 10 and notify that the stay or congestion state has occurred, thereby prompting confirmation of the passenger conveyor management state. .

図２は、本発明の一実施形態による乗客コンベアの安全制御装置の一連の動作の流れを示す処理フローチャートである。   FIG. 2 is a process flowchart showing a flow of a series of operations of the passenger conveyor safety control device according to the embodiment of the present invention.

ここで、レーザスキャンセンサ１ａ，１ｂは、その内部のレーザ光投光部と受光部を回転させ、反射到達時間に基く物体との距離ｒと、受光部の回転角度θを出力する。このデータは、ステップ２０１において、信号処理装置２に設けているシリアル通信送受信部５を介してＣＰＵ３にて受信される。このデータは、円座標系のデータであるため、検出距離ｒ、回転角度をθとしたとき、ＸＹ平面座標上の検出点の位置を、次式で求めることができる。   Here, the laser scan sensors 1a and 1b rotate the laser light projecting unit and the light receiving unit therein, and output the distance r to the object based on the reflection arrival time and the rotation angle θ of the light receiving unit. In step 201, this data is received by the CPU 3 via the serial communication transmitting / receiving unit 5 provided in the signal processing device 2. Since this data is data in a circular coordinate system, when the detection distance r and the rotation angle are θ, the position of the detection point on the XY plane coordinates can be obtained by the following equation.

ｘ＝ｒ・ｃｏｓθ………………………………………………………………………（１）
ｙ＝ｒ・ｓｉｎθ………………………………………………………………………（２）
レーザスキャンセンサ１ａ，１ｂによるスキャンにより、検出対象物の表面の連続点の座標マップを作成する（ステップ２０２）。次に、ステップ２０３において、予め計測しておいた利用客がない状態における座標データマップと重ね合わせ、固定障害物の座標データを除去する。これによって、ステップ２０４では、乗客コンベア上の現在の平面座標データマップにより、乗客の輪郭データを得ることができる。また、ステップ２０５では、乗客の輪郭データから、乗客の中心点の座標を算出し、信号処理装置２の内部のメモリ４に記録する。この記録データを、過去一定時間前（１秒程度前）まで記録しておく。そして、ステップ２０６で短時間（１００ｍｓ程度）毎に、対象物中心点の移動量を監視し、ステップ２０７で、個々の検出対象物の移動速度を算出する。 x = r · cos θ ……………………………………………………………………… (1)
y = r · sinθ ……………………………………………………………………… (2)
A coordinate map of continuous points on the surface of the detection target is created by scanning with the laser scan sensors 1a and 1b (step 202). Next, in step 203, the coordinate data map in a state where there is no customer measured in advance is superimposed, and the coordinate data of the fixed obstacle is removed. Thus, in step 204, the passenger's contour data can be obtained from the current plane coordinate data map on the passenger conveyor. In step 205, the coordinates of the passenger's center point are calculated from the passenger's contour data and recorded in the memory 4 inside the signal processing device 2. This recorded data is recorded until a certain past time (about 1 second before). In step 206, the movement amount of the object center point is monitored every short time (about 100 ms), and in step 207, the movement speed of each detection object is calculated.

ここで、ステップ２０８において、検出対象物の移動速度が、予定のしきい値を下回った場合、乗客の立ち止まりや滞留を検出する。   Here, in step 208, when the moving speed of the detection object falls below a predetermined threshold value, the stoppage or stay of the passenger is detected.

乗客の立ち止まりや滞留を検出しなかった場合でも、ステップ２０９に進んで、検出物体多数検出しきい値を上回った場合には、乗客コンベア乗降部の混雑状態と判定する。   Even if the stoppage or stay of the passenger is not detected, the process proceeds to step 209, and if the detected object multiple detection threshold value is exceeded, it is determined that the passenger conveyor boarding / exiting part is congested.

ステップ２１０において、乗客の立ち止まりや滞留あるいは乗降部の混雑状態が一定時間Ｔ１を超えて継続したと判断した場合には、ステップ２１１において、要警告状態として、音声合成装置１１及びスピーカ１２ａもしくは１２ｂを用いて警告放送を行う。例えば、「混雑しておりますので、立ち止まらずにお進み下さい。」などである。   In step 210, if it is determined that the passenger's stoppage or stay or congestion state of the boarding / exiting portion has continued for a certain time T1, the voice synthesizer 11 and the speaker 12a or 12b are set as warning states in step 211. Use to broadcast warnings. For example, “Because it is crowded, please proceed without stopping.”

また、遠隔監視装置１０等により、管理会社が遠隔監視を実施している乗客コンベアにおいては、ステップ２１２において、滞留・混雑が発生し、警告している旨の発報を行う。   Further, in the passenger conveyor that is being remotely monitored by the management company using the remote monitoring device 10 or the like, in step 212, a notification that a stay / congestion has occurred and a warning has been issued is issued.

さらに、乗客コンベアの降り口付近乗降部において、立ち止まり・滞留状態判定や混雑状態判定がなされた状態が継続し、ステップ２１３において、一定時間Ｔ２を超えたと判断した場合は、乗客コンベアの利用客が降り口付近にあふれて危険な状態になる惧れがある。このため、ステップ２１４において、音声合成装置１１およびスピーカ１２ａ，１２ｂを用いて「速度が遅くなりますので、ご注意下さい。」と注意喚起放送を行い、乗客コンベア制御装置７からインバータ装置８に出力周波数・電圧を低下させるよう指令する。これにより、乗客コンベア降り口部へ到達する単位時間当たりの利用客数を減少させ、降り口部の滞留状態や混雑状態の解消を図る。   Furthermore, the state where the stop / staying state determination and the congestion state determination are continued at the entrance / exit near the exit of the passenger conveyor. If it is determined in step 213 that the predetermined time T2 has been exceeded, the passenger conveyor user There is a risk of overflowing near the exit and becoming dangerous. For this reason, in step 214, the voice synthesizer 11 and the speakers 12a and 12b are used to broadcast a warning message “Please note that the speed will be slowed” and output from the passenger conveyor control device 7 to the inverter device 8. Command to reduce frequency and voltage. As a result, the number of passengers per unit time reaching the passenger conveyor exit is reduced, and the staying state and congestion of the exit are reduced.

運転速度を低下させた後、ステップ２１５において、乗客コンベア降り口付近における立ち止まりや滞留状態が解消したと判断した場合には、乗客コンベアの速度を通常の速度に戻す必要がある。そこで、ステップ２１６において、音声合成装置１１およびスピーカ１２ａ，１２ｂを用いて「速度が速くなりますので、ご注意下さい。」と注意喚起放送を行い、乗客コンベア制御装置７からインバータ装置８に出力周波数・電圧を上昇させるよう指令する。これにより、駆動用交流電動機９の回転速度を元に戻し、乗客コンベアの運転速度を元の速度に復帰させる。   After reducing the operation speed, if it is determined in step 215 that the stop or staying state near the passenger conveyor exit has been eliminated, it is necessary to return the passenger conveyor speed to the normal speed. Therefore, in step 216, using the speech synthesizer 11 and the speakers 12a and 12b, a warning broadcast is made, “Please note that the speed will be faster.”, And the output frequency from the passenger conveyor control device 7 to the inverter device 8 is transmitted. • Command the voltage to increase. Thereby, the rotational speed of the drive AC motor 9 is returned to the original, and the operation speed of the passenger conveyor is returned to the original speed.

一方、乗客コンベア降り口付近における立ち止まりや滞留状態が解消せず、ステップ２１５において、一定時間Ｔ３を超えたと判断した場合は、乗客コンベアの利用客が降り口付近にあふれて危険である。このため、ステップ２１７において、音声合成装置１１およびスピーカ１２ａ，１２ｂを用いて「停止しますので、ご注意下さい。」と注意喚起放送を行い、乗客コンベア制御装置７からインバータ装置８に出力周波数・電圧をゼロまで低下させるよう指令する。そして、速度が十分に低下し、ほぼゼロになったところでブレーキ装置で乗客コンベアを機械的に静止保持し、最終的にモータ９への給電を絶つ。これにより、乗客コンベア降り口部への利用客の移動を停止させ、降り口部付近での危険を抑止する。   On the other hand, if the stoppage or staying state in the vicinity of the passenger conveyor exit is not resolved and it is determined in step 215 that the predetermined time T3 has been exceeded, passengers of the passenger conveyor overflow around the exit and it is dangerous. For this reason, in step 217, the voice synthesizer 11 and the speakers 12a and 12b are used to broadcast a warning message “Please note that it will stop.” From the passenger conveyor control device 7 to the inverter device 8, Command the voltage to drop to zero. Then, when the speed is sufficiently reduced to almost zero, the passenger conveyor is mechanically held stationary by the brake device, and finally the power supply to the motor 9 is cut off. Thereby, a passenger's movement to a passenger conveyor exit part is stopped, and the danger in the vicinity of an exit part is suppressed.

また、遠隔監視装置１０等により、管理会社が遠隔監視を実施している乗客コンベアにおいては、ステップ２１８において、滞留・混雑が発生し、自動停止させた旨の発報を行う。   In addition, in the passenger conveyor that is being remotely monitored by the management company by using the remote monitoring device 10 or the like, in step 218, a notification that the stagnation / congestion has occurred and the vehicle has been automatically stopped is issued.
