Abstract

PURPOSE:To predict a crowded floor with high precision and to prevent the occurrence of the presence of passengers shut out from riding in an elevator, by a method wherein the load of a preceding cage is stored classified by each floor direction, the stop time of a subsequent cage is detected, and when the load of the preceding cage exceeds a given value and the stop time of the subsequent cage exceeds a given value in some direction at some floor, a relief cage is allotted to the floor. CONSTITUTION:A microcomputer 10 performing function as that of a group managing device is provided with function as a means 14 to store the load of a preceding cage, function as a means 13 to detect the stop time of a subsequent cage, and function as means 14 to allot a relief cage in addition to ordinary allotment function. Since from both the load of the preceding cage and the stop time of the subsequent cage, the occurrence of the presence of passengers shut out from riding in an elevator is predicted, precision is improved compared with a case in which it is predicted only from the load of a cage and the frequency of waiting passengers being present. Betides, a number of waiting passengers detecting device is not needed at each elevator stop, resulting in improvement of economical efficiency. Further, since a relief cage is allotted during the stop of the subsequent cage, a waiting time can be shortened and serviceability can be improved.

【発明の詳細な説明】 〔産業上の利用分野〕 この発明はエレベータの群管理装置の改良に関し、特に
混雑階における積み残し防止に有効なものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an improvement in a group control device for elevators, and is particularly effective in preventing unstacked items on crowded floors.

タが乗場呼びに応答して停止しても全員が乗り切れない
ことが生じる。On extremely crowded floors, such as the entrance floor during dispatch, the floor with the cafeteria during lunch, and the floor with the meeting room at the end of the meeting, it may not be possible for everyone to get through even if the elevator stops in response to a hall call. .

その場合、その乗場に対し優先的にサービスをする手段
が種々考えられている。In that case, various means have been considered to provide preferential service to that landing.

待客数を予測し追加割当てを行う方法などが考えられて
いる。For example, a device for detecting the number of waiting passengers may be installed at the landing to allocate additional cars to that floor when it is predicted that there will be some unloaded cars, or if it is detected that a car is full and has departed, the system will call the landing for that floor. Considered methods include automatic registration, and methods that use the frequency of waiting passengers and the elapsed time since the departure of the previous car to predict the number of waiting passengers at a particular landing and make additional allocations.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

乗場に待客数検出装置を設ける方法ではコストの面で問
題があり、しかも中間階で上昇方向の待客と下降方向の
待客とを区別して検出することが困難である。The method of providing a detection device for the number of waiting passengers at the landing has problems in terms of cost, and furthermore, it is difficult to distinguish and detect passengers waiting in the ascending direction and those waiting in the descending direction on intermediate floors.

また、カゴが満員で出発すると乗場呼びを自動登録する

場の待客数を予測する方法は過去の統計的な値を用いる
ため、何れも予測精度の面で問題があり、その結果無駄
な運転を引き起こして群全体の効率を悪化させる恐れが
ある。In addition, with the method of automatically registering a landing call when a car departs when it is full, it is predicted that there will be backlogs just because the car is full, and the frequency of occurrence of waiting passengers is used to predict the number of passengers waiting at the landing. Since these methods use past statistical values, they all have problems in terms of prediction accuracy, which may result in unnecessary operation and deteriorate the efficiency of the group as a whole.

本発明はこうした問題点を解決し、すべての階で精度よ
く経済的に混雑階を予測し、積み残しの発生を防止する
ことを目的とする。It is an object of the present invention to solve these problems, accurately and economically predict crowded floors on all floors, and prevent the occurrence of backlogs.

〔課題を解決するための手段〕[Means to solve the problem]

上記目的を達成するため、本発明は各階、方向別に先発
カゴの負荷を記憶する手段と、各階、方向別に次発カゴ
の停止時間を検出する手段と、或る階の或る方向におい
て先発カゴの負荷が所定値以上で、次発カゴの停止時間
が所定値を超えたとき、その階に救援カゴを割当てる手
段とを備えた構成としている。In order to achieve the above object, the present invention provides means for storing the load of the first car for each floor and direction, means for detecting the stopping time of the next car for each floor and direction, and means for detecting the stop time of the next car for each floor and direction. and means for allocating a rescue car to that floor when the load on the next car exceeds a predetermined value and the stopping time of the next car exceeds a predetermined value.

〔作用〕[Effect]

このような構成において、ある階を最新に出発したカゴ
についてその出発直後の負荷状態を、その階のその運転
方向における先発カゴの負荷とし、これを各階、方向別
に記憶しておく。In such a configuration, the load state of the car that most recently departed from a certain floor immediately after its departure is taken as the load of the preceding car in that driving direction on that floor, and this is stored for each floor and direction.

一方、ある階に運転方向を持って現在停止しているカゴ

し、さらに次発カゴの停止時間が所定値を超えたことを
検出したとき、その階のその運転方向に救援カゴが割当
てられる。On the other hand, for a car currently stopped on a certain floor with its driving direction, the stopping time after arrival is measured, and this is detected as the stopping time of the next car on that floor in that driving direction. In a certain driving direction on a certain floor, when it is detected that the first car departs with a load higher than a predetermined value (for example, 80% or more) and the stopping time of the next car exceeds a predetermined value, A rescue car is assigned to that driving direction of the floor.

すなわち、本発明では先発カゴが一定以上の乗客を乗せ

他の理由で停止時間が長いことも考えられ、また先発カ
ゴの負荷だけでは混雑状態が継続するのか否か不明なた
め、両方の条件でより正確な判断を、しかも次発カゴの
出発前に行えるようにしたものである。In other words, in the present invention, it is considered that the frequency of occurrence of passengers waiting on that floor has started to increase because the first car departed with more than a certain number of passengers on board. We believe that it takes a long time to get on board due to the large number of passengers waiting on the floor, so we are assigning relief baskets to this floor. This is because it is possible that the stoppage time is simply long or that the stoppage time is long for other reasons, and it is unclear whether the congestion state will continue based only on the load of the first car, so a more accurate judgment can be made under both conditions. Moreover, this can be done before the next car departs.

（実施例〕 以下、本発明の一実施例を図面に基づいて説明する。(Example〕 Hereinafter, one embodiment of the present invention will be described based on the drawings.

第１図は本発明の全体の構成を示す図で、ここでは説明

の場合について説明する。FIG. 1 is a diagram showing the overall configuration of the present invention. Here, for convenience of explanation, a case will be described in which there are four elevators to be controlled, A to D.

る。In FIG. 1, IA is the operation control device that manages the operation of No. A car, and similarly, IB-10 is the operation control device of No. B to D cars, respectively. 2 is a car information signal that indicates the situation of each car, such as its position, operating status, and load status; 3 is a rescue command signal given to a car that satisfies a certain condition; and 10 is a microcontroller that functions as a group management device. on the computer,
In addition to the normal allocation function, it has a function as a means 12 for storing the load of the first car, a function as a means 13 for detecting the stop time of the next car, and a function as a means 14 for allocating a relief car. . 11 is an input/output port.

ＸをＤＮ（下降方向）とし、手順Ｍ４で今度は各階の下
降について救援カゴの必要の有無をチエツクする。First, in step M1, the driving direction X is set to UP (ascending direction), and in step M2, it is checked whether or not a rescue basket is required for each floor in the ascending direction (details will be described later). Next, in step M3, the driving direction X is set to DN (downward direction), and in step M4, it is checked whether or not a rescue car is required for descending each floor.

第３図は、第２図に示した手順Ｍ２の詳細を示すフロー
チャートで、手順Ｍ４についても全く同−七あるため、
以下は上昇方向の場合についてのみ説明を行う。FIG. 3 is a flowchart showing the details of step M2 shown in FIG.
In the following, only the case of upward movement will be explained.

第３図において、Ｆは階床を表わす変数であり、手順Ｎ
１でＦ−０として初期設定を行った後、手順Ｎ２とＮ３
によりＦ＝１階から最上階まで順次　　゛チエツクを行
う。In Figure 3, F is a variable representing the floor, and step N
After initializing as F-0 in step 1, perform steps N2 and N3.
Check sequentially from F=1st floor to the top floor.

まずＦ＝１階について、手順Ｎ４で１階上昇方向に停止
中のカゴが存在しているか否かをチェソりする０本発明
では救援カゴの割当ての条件として次発カゴ（運転方向

て２階上昇方向のチエツクを行う、もし１階に上昇方向
を持ったカゴ（次発カゴ）が停止している場合には、そ
の停止時間がｔが所定値ｔ、より大きいか否かをチエツ
クする。First, regarding the F = 1st floor, in step N4, it is checked whether there is a stopped car in the upward direction of the 1st floor. Since one of the conditions is the stop time of the currently stopped car, if there is no stopped car in the direction of ascending to the first floor, the process returns from step N4 to step N2, and then sets F=2 to ascend to the second floor. The direction is checked. If a car with an upward direction (next car) is stopped on the first floor, it is checked whether its stopping time t is greater than a predetermined value t.

ここで１階上昇方向の次発カゴの停止時間ｔは、第１図
において検出手段１３がカゴ情報信号２からカゴが１階
上昇方向に停止する毎に停止してからの経過時間を計測
しており（カゴが出発するとリセットする）、その値を
用いる。なお他の階の次発カゴの停止時間も同様である
。Here, the stop time t of the next car in the upward direction to the first floor is determined by the detecting means 13 measuring the elapsed time from the car stopping each time the car stops in the upward direction to the first floor based on the car information signal 2 in FIG. (resets when the car leaves) and uses that value. The same holds true for the stop times of the next cars on other floors.

第３図に戻って、この停止時間ｔが所定値ｔ、を超えて
いれば手順Ｎ５からＮ６へと進み、今度は１階上昇方向
の先発カゴの負荷が所定値Ｗ０以上（例えば定格積載の
８０％以上）であったか否かをチエツクする。ここで１

出発する毎にそのときの負荷状態を１階上昇方向におけ
る先発カゴの負尚として更新記憶しているのでその値を
用いる。他の階の先発カゴの負荷も同様である。Returning to FIG. 3, if this stop time t exceeds the predetermined value t, the process proceeds from step N5 to N6, and this time the load of the first car in the upward direction to the first floor is greater than or equal to the predetermined value W0 (for example, the rated load 80% or more). Here 1
In FIG. 1, the storage means 12 calculates the load of the first car in the ascending direction from the car information signal 2. Each time a car departs from the first floor in the upward direction, the load state of the first car in the ascending direction is determined by the storage means 12. Since it is updated and stored as a negative value, that value is used. The same applies to the loads of the starting baskets on other floors.

なお、カゴの負荷はカゴ内荷重、カゴ内人数等実質的に
カゴの負荷に対応するものであればどのようなものを用
いてもよい。Note that the load on the car may be any load that substantially corresponds to the load on the car, such as the load inside the car or the number of people inside the car.

第３図に戻って、−階上昇方向の先発カゴの負荷が所定
値Ｗ０以上であった場合には手順Ｎ６からＮ７へと進み
、救援カゴの割当てが行われ、いま１階上昇方向に停止
しているカゴを除く他のカゴの中から最適なカゴを選択
し、そのカゴに救援指令を与える。Returning to FIG. 3, if the load of the first car in the -floor ascending direction is equal to or greater than the predetermined value W0, the process proceeds from step N6 to N7, where a relief basket is allocated and the car is now stopped in the first floor ascending direction. The most suitable basket is selected from among the other baskets excluding the one in use, and a rescue command is given to that basket.

すなわち、１階上昇方向において、先に出発したカゴの
負荷が所定値以上で次に停止したカゴの停止時間がある
程度長いと、その時点で１階上昇方向に救援カゴが割当
てられることになる。That is, in the first floor ascending direction, if the load of the car that departed first is equal to or greater than a predetermined value and the stopping time of the next stopped car is a certain length of time, at that point a rescue car is assigned to the first floor ascending direction.

同様にして手順Ｎ２〜Ｎ７を繰り返すことにより、２階
から順次チエツクが行われ、すべての階について終了す
ると手順Ｎ３からリターンへと進み、第２図に戻って今
度は下降方向の各階について救援が必要か否かのチエツ
クが行なわれる。By repeating steps N2 to N7 in the same way, checks are performed sequentially from the second floor, and when all floors are checked, the process proceeds to return from step N3, returning to Figure 2, and this time, rescue is performed on each floor in the descending direction. A check is made to see if it is necessary.

なお、上記の実施例において、手順Ｎ５の所定値ｔ、は
各階、方向により異なった値としてもよく、例えば、そ
の階、方向の呼びに応答したカゴの平均停止時間、或い
は負荷が所定値に達すると予測される乗込み時間から救
援カゴのその階への予想到着時間を引いた値をその階の
所定値ｔ０とすることなどが考えられる。In the above embodiment, the predetermined value t in step N5 may be a different value depending on each floor or direction. For example, the predetermined value t in step N5 may be different depending on the floor or direction. It is conceivable to set the predetermined value t0 for that floor as the value obtained by subtracting the expected arrival time of the relief car to that floor from the expected boarding time.

同様に手順Ｎ６における所定値Ｗ、も各階、方向ですべ
て同一の値とする必要はなく、各階の性質に応じて或い
は学習などにより変化させるようにすることもできる。Similarly, the predetermined value W in step N6 does not need to be the same value for each floor and direction, and may be changed depending on the characteristics of each floor or by learning.

〔発明の効果〕〔Effect of the invention〕

本発明によれば、先発カゴの負荷と次発カゴの停止時間
の両方から積み残し発生の予測をするようにしたので、
かごの負荷や待客の発生頻度だけで予想するよりも精度
が向上し、しかも各乗場に待客数検出装置等を必要とし
ないので経済的である。According to the present invention, the occurrence of unloaded items is predicted based on both the load of the first car and the stop time of the next car.
This method is more accurate than predictions based only on the car load and the frequency of waiting passengers, and is economical because it does not require a device to detect the number of waiting passengers at each landing.

また次発カゴが出発して実際に積み残しが発生してから
救援カゴを割当てるのではなく、次発カゴの停止中に救
援カゴを割当てるので、救援カゴの到着が迅速となり、
待時間が短縮されてサービス性が向上する。In addition, instead of assigning a rescue basket after the next basket departs and there is actual backlog, the rescue basket is allocated while the next basket is stopped, so the rescue basket can arrive more quickly.
Waiting time is reduced and serviceability is improved.
