Description

本発明は、群管理エレベータシステムに係り、特に、エレベータの利用状況を学習するものに好適である。   The present invention relates to a group management elevator system, and is particularly suitable for learning a use situation of an elevator.

群管理エレベータシステムは、複数のかごを１つのグループとして扱うことにより、利用者に対して効率的なかごの運行サービスを行うエレベータシステムであり、ある階床で新たなホール呼びが発生した場合、グループの中から最適なかごを１つ選択して、そのかごに先のホール呼びを予測待ち時間などによる割当て評価関数に基づき割当てを行う。つまり、新たなホール呼びに対する予測待ち時間を算出して、予測待ち時間が最小となるかごに、そのホール呼びを割当てる。   The group management elevator system is an elevator system that provides efficient car operation services to users by treating multiple cars as one group. When a new hall call occurs on a certain floor, One optimal car is selected from the group, and the previous hall call is assigned to the car based on an assignment evaluation function based on a predicted waiting time or the like. That is, the predicted waiting time for a new hall call is calculated, and the hall call is assigned to the car having the smallest predicted waiting time.

また、予測待ち時間の精度を向上させるため、ビル固有の交通需要を階床間別に学習し、未通過階の未発生ホール呼びによる停止確率と、それに派生するかご呼びの発生確率を予測して到着予測時間を求めることが知られ、例えば、特許文献１に記載されている。   In addition, in order to improve the accuracy of the forecast waiting time, the building-specific traffic demand is learned between floors, and the probability of stoppage due to a call that has not occurred on a non-passing floor and the probability of occurrence of a car call derived therefrom are predicted. It is known to obtain the estimated arrival time, and is described in Patent Document 1, for example.

さらに、ビル固有の交通需要を階床間別に学習し、未通過階の未発生ホール呼びによる停止確率と、それに派生するかご呼びの発生確率を予測して到着予測時間を求めることが知られ、例えば、特許文献２に記載されている。   Furthermore, it is known to learn the building-specific traffic demand by floor, and to predict the arrival time by predicting the probability of stoppage due to unoccurred hall calls on non-passing floors and the probability of occurrence of car calls derived from it, For example, it is described in Patent Document 2.

さらに、かごの荷重変化に応じて、乗り客および降り客量を計測し、かご呼びが発生しなかった階床との関係から階床間の行先階交通量を求めることが知られ、例えば、特許文献３に記載されている。   Furthermore, it is known to measure the passengers and the number of passengers according to the load change of the car, and to determine the destination floor traffic between the floors from the relationship with the floor where the car call did not occur, for example, It is described in Patent Document 3.

上記特許文献に記載のものでは、交通需要の学習は推測による乗り降り人数になってしまうため、乗り客および降り客量と階床との関係を正確に求められるものでなく、交通需要に対して必ずしも最適になるとは限らなかった。   In the thing of the said patent document, since learning of traffic demand will become the number of people getting on and off by estimation, the relationship between a passenger and the amount of passengers and a floor is not calculated | required correctly, It was not always optimal.

本発明の目的は、上記従来技術の課題を解決し、階床間別に乗り降り人数を正確に学習し、学習結果を群管理制御に反映してより性能を向上させることにある。   An object of the present invention is to solve the above-described problems of the prior art, to accurately learn the number of people getting on and off between floors, and to improve the performance by reflecting the learning result in the group management control.

上記目的を達成するため、本発明は、複数階床をサービスする複数のかごと、前記エレベータの各階床乗場に設置されホール呼びを入力する乗り場呼び装置と、前記階床間別の乗り降り人数を求め、新たな前記ホール呼びに対する予想待ち時間を算出して前記複数台のかごの中から前記かごを選択する制御装置と、を備えた群管理エレベータシステムにおいて、前記かごの内部を撮像した画面とする監視カメラと、前記監視カメラとデータの送受信を行う画像処理装置と、を備え、画像処理装置は、利用者が前記画面外から前記画面内に入ってきたとき、利用者が乗り込んだことを判別し、乗り込んだ前記利用者が前記画面外に出たとき、降りたとして判別する、ものである。     In order to achieve the above object, the present invention obtains a plurality of cars that serve a plurality of floors, a hall call device that is installed in each floor landing of the elevator and inputs hall calls, and the number of people getting on and off by each floor. And a control device that calculates an expected waiting time for the new hall call and selects the car from the plurality of cars, and has a screen that captures the interior of the car. A monitoring camera; and an image processing device that transmits and receives data to and from the monitoring camera. The image processing device determines that a user has boarded when the user enters the screen from outside the screen. Then, when the boarded user goes out of the screen, it is determined that the user got off.

本発明によれば、かごの内部を撮像した監視カメラの画面に利用者が画面外から画面内に入ってきたとき、利用者が乗り込んだと判別し、利用者が画面外に出たとき、降りたとして判別するので、エレベータ利用状況を階床間別に正確に学習することができ、予測待ち時間の精度、割当てられたかごの適正さなど群管理制御の性能を向上することができる。   According to the present invention, when a user enters the screen of the surveillance camera that images the inside of the car from the outside of the screen, it is determined that the user has boarded, and when the user goes out of the screen, Since it is determined as getting off, it is possible to accurately learn the elevator usage status between floors, and it is possible to improve the performance of the group management control such as the accuracy of the predicted waiting time and the appropriateness of the assigned car.

図２はかご内設置の監視カメラの映像であり、ほぼかご内の全域を撮像した画面としている。Ａ１０１はかご内にいる人でＡ１０２は現在かご内に乗り込もうとしている人である。監視カメラ６１と号機制御装３１、監視カメラ６２と号機制御装３２、監視カメラ６３と号機制御装３３はそれぞれ画像処理装置２０１を介してデータの送受信を行っている。   FIG. 2 is an image of a surveillance camera installed in the car, and is a screen that captures the entire area of the car. A101 is a person in the car and A102 is a person who is currently in the car. The surveillance camera 61 and the machine controller 31, the surveillance camera 62 and the machine controller 32, and the surveillance camera 63 and the machine controller 33 exchange data via the image processing device 201.

画像処理装置２０１は、利用者が画面外から画面内に入ってきたとき、利用者が乗り込んだことを判別して記憶し、かご内位置及び特徴を固有の番号を付加して記憶する。また、乗り込んだ利用者が画面外に出るまで、記憶した特徴から画面内のどこに利用者がいるかを示す位置を判別する。そして、利用者が画面外に出るまで追跡し、画面外に出たとき、降りたとして判別して記憶する。   When the user enters the screen from the outside of the screen, the image processing apparatus 201 determines and stores that the user has boarded, and stores the position and characteristics in the car with a unique number added. Further, until the boarded user goes out of the screen, a position indicating where the user is on the screen is determined from the stored characteristics. Then, the user is traced until the user goes out of the screen, and when the user goes out of the screen, it is determined that the user has gone down and stored.

さらに、それぞれの利用者に固有の番号Ａ，Ｂ…Ｎを付加し、利用者毎に乗り階、降り階を図３に示すような乗客管理テーブルとして記憶する。階床を示すかご位置データは、号機制御装置３１から画像処理装置２０１へ送信され、利用者が乗り込んだと判別されたとき、かご位置データを参照して乗客管理テーブルの乗り階の欄に現在のかご位置として追加される。また、利用者が降りたと判別されたときは、乗客管理テーブルの降り階の欄に、そのときの号機制御装置３１から送信されたかご位置データを乗客管理テーブルの降り階の欄に追加すると共に、乗客管理テーブルによる乗り階・降り階を群管理御装置２に送信する。例えば、２階から乗った人が５階で降りた場合は乗り階２、降り階５と言う情報が群管理制御装置２へ送られてくる。   Furthermore, numbers A, B... N unique to each user are added, and the boarding floor and the landing floor are stored for each user as a passenger management table as shown in FIG. The car position data indicating the floor is transmitted from the machine control device 31 to the image processing apparatus 201, and when it is determined that the user has boarded, the car position data is referred to in the column of the floor of the passenger management table with reference to the car position data. Added as car position. In addition, when it is determined that the user has exited, the car position data transmitted from the machine control device 31 at that time is added to the column of the descending floor of the passenger management table, and the car position data transmitted at that time is added to the column of the descending floor of the passenger management table. The boarding / descending floors according to the passenger management table are transmitted to the group management device 2. For example, when a person who has got on the second floor gets off at the fifth floor, the information of the second floor and the fifth floor is sent to the group management control device 2.

群管理制御装置２は、図４に示す縦軸を乗り階、横軸を降り階とした階床間別乗り降り人数テーブルを備えており、監視カメラ３１、３２、３３から送られてきたデータを基に階床別乗り降り人数テーブルを更新する。乗り階２、降り階５と言う情報が来た場合は乗り階２、降り階５のところに１を足して追記する。階床別乗り降り人数テーブルは一定の期間又は総人数で区切り、区切り毎に学習結果として階床別乗り降り人数学習テーブルとして保存しておく。従って、階床別乗り降り人数学習テーブルによって階床間別乗り降り人数、エレベータ利用状況を階床間別に正確に把握し、到着予測時間を精度良く演算し、群管理制御の性能を向上することができる。   The group management control device 2 includes a table of number of people getting on and off between floors with the vertical axis shown in FIG. 4 as the floor and the horizontal axis as the floor, and the data sent from the monitoring cameras 31, 32, and 33 are received. Based on the number of people getting on and off by floor, the table is updated. When information on boarding floor 2 and landing floor 5 is received, 1 is added to boarding floor 2 and landing floor 5 and added. The number of people getting on and off by floor is divided by a certain period or the total number of people, and the number of people getting on and off by floor is stored as a learning result for each division as a learning result. Therefore, it is possible to accurately understand the number of people getting on and off between floors and the usage status of the elevators by the floor by using the learning table for getting on and off by floor, calculating the arrival time accurately, and improving the performance of group management control. .
