を乗場に予報表示するエレベータの群管理装置に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention selects an optimal car for a hall call from a plurality of elevator cars and assigns it to an elevator, and also an elevator that displays a forecast on the hall. The present invention relates to a group management device.
複数台のエレベータが並設された場合は、通常群管理運
転が行われる。When a plurality of elevators are installed side by side, normal group management operation is performed.
現在この群管理運転の主流をなすのは呼び割当て方式で
あるが、これは乗場呼びが登録されるとこれに応答すべ

けを応答させるようにして、運転効率の向上及び乗場待
時間の短縮を図るものである。Currently, the call allocation method is the mainstream of this group management operation, but when a hall call is registered, the car that should respond to this is selected using an evaluation function, etc., and the hall call is assigned to this car. At the same time as the allocation, the forecast of the allocated car is displayed at the landing. Then, only the assigned car is made to respond to the hall call so as to improve the driving efficiency and shorten the hall waiting time.

いるときは、まず運転方向と同方向の呼びに順次応答し
て行き、前方に呼びがなくなれば自動的に運転方向を逆
転し、今度は順次その方向の呼びに答えて運転し、呼び
がなくなると停止する。At this time, each car selects the hall call assigned to its own machine and the celecole method for the car call registered in its own machine,
That is, it is usual to drive by a selective collective system (directional automatic riding system). That is, each car is activated by the generation of a car call of its own machine or a landing call assigned to its own machine, and when it is in charge of multiple calls, it first responds sequentially to calls in the same direction as the driving direction, When there are no more calls ahead, the driving direction is automatically reversed, and this time the cars answer the calls in that direction one by one and drive, and stop when there are no more calls.
新規に発生した乗場呼びをあるかごに割当てた場合、そ
のかごが上記のようにセレコレ方式でサービスするのが
最も効率が良いとは限らない。これを第４図により説明
する。When a newly generated hall call is assigned to a car, it is not always most efficient for the car to serve by the celecole method as described above. This will be described with reference to FIG.
第４図は、いま新たに３階上昇方向の乗場呼び3Uが発生
し、これがＡ号機に割当てられた状態（他の号機は図示
省略）を示した図である。4DはＡ号機に既に割当てられ
ている４階下降方向の乗場呼びであり、10K,7K,1Kはそ
れぞれ乗場呼び3Uと4Dから派生すると予想される10階,7
階,1階のかご呼びを示している。FIG. 4 is a diagram showing a state in which a new hall call 3U in the ascending direction on the third floor is newly generated and is assigned to the car A (other cars are not shown). 4D is a hall call in the descending direction on the 4th floor that has already been assigned to Unit A, and 10K, 7K, 1K are expected to be derived from hall calls 3U and 4D, respectively.
Shows the car calls on the 1st and 2nd floors.
このような場合、従来は第４図（ａ）のように、まず乗

ようにまず乗場呼び4Dに応答しそこから派生する１階の
かご呼び1Kにサービスした後、乗場呼び3Uに応答した方
が各乗場呼びの待時間の合計が小さくなり、全体から見
て効率が良い。In such a case, conventionally, as shown in Fig. 4 (a), first, the car calls 7K and 10K are derived in response to the hall call 3U.
The service is performed by the celecole method such as responding to the hall call 4D after reversing the driving direction. However, if you drive in this way, the waiting time for the hall call 4D will be very long, so in such a case, as shown in Fig. 4 (b), the hall call 4D first responds to the hall call 4D and is derived from it. After servicing 1K, responding to 3U hall calls will reduce the total waiting time for each hall call, which is more efficient overall.
しかし第４図（ｂ）のような運転を行うためには、各号
機の運転方式をセレコレ方式に限定することなく、呼び
の状況に応じてその都度運転ルートを決定するような運
転方式に改めねばならないといった問題点がある。However, in order to perform the operation as shown in Fig. 4 (b), the operation method of each unit is not limited to the celecole method, but is changed to an operation method that determines the operation route each time according to the calling situation. There is a problem that it must be done.
本発明は上記問題点を解決するためになされたもので、
各号機の運行制御装置はセレコレ方式のままで変更の必
要がなく、かつ実際には運転方式を変えることのできる
群管理装置を提供することを目的とする。The present invention has been made to solve the above problems,
It is an object of the present invention to provide a group management device in which the operation control device of each unit does not need to be changed as it is in the selection system and the operation system can be actually changed.
このため、本発明で新たに乗場呼びが発生すると、従来

に出力する構成とする。Therefore, when a hall call is newly generated in the present invention, an optimum car is selected from a plurality of cars in the group management control device as in the conventional case, and the operation control device for the car is assigned with the signal for assigning the hall call. However, it does not output the allocation signal as soon as the optimum car is selected, but is provided with means for determining the output timing of the allocation signal, and the allocation signal is output via the timing determination means. On the other hand, a means for outputting a prediction display signal for guiding the selected car to the hall is provided, and this prediction display signal is immediately output regardless of the timing of the allocation signal when the optimum car is selected. The configuration.

以上の構成において、本発明の動作を説明する。第３図
は本発明による割当処理の手順を示すフローチャートで
ある。The operation of the present invention having the above configuration will be described. FIG. 3 is a flowchart showing the procedure of the allocation process according to the present invention.
まず、新たな乗場呼びが発生すると、群管理装置10の割

割当判断は従来と同様に行われ、例えば各乗場呼びの予
測待時間等を各かご毎に演算してその結果から最適なか
ごを選択する。First, when a new hall call occurs, the allocation means 12 of the group management device 10 determines allocation (procedure M1). This allocation determination is performed in the same manner as in the conventional case. For example, the estimated waiting time of each hall call is calculated for each car, and the optimum car is selected from the result.
いま、ここでは第４図の状態を考え、新たに発生した３
階上昇方向の乗場呼び3Uに対して割当判断が行われ、そ

たため、第４図（ａ）に示した順序で各乗場呼びとかご
呼びに応答していくことになる。Now, considering the state of Fig. 4, a newly generated 3
It is assumed that the allocation decision is made for the hall call 3U in the ascending direction, and as a result, Unit A is selected. At this time, conventionally, since the allocation signal was immediately sent to the operation control device of the Unit A, it will respond to each hall call and car call in the order shown in FIG. 4 (a).
しかしこの発明では、Ａ号機が選択された時点で直ちに
割当信号を送るのではなく、乗場に案内表示するための
予報表示信号のみを予報表示信号出力手段14から、Ａ号

が損われることはない。However, in the present invention, the allocation signal is not sent immediately when the car No. A is selected, but only the prediction display signal for displaying the guidance at the hall is sent from the prediction display signal output means 14 to the operation control device 20A of the car A. Output (procedure M2). In response to this forecast display signal, the arrival forecast light control means 23A turns on the arrival forecast light of the car A on the third floor to notify the waiting passengers of the car that the car A responds to the hall call 3U. Therefore, according to the present invention as well, when the hall call is registered, which car responds is immediately displayed at the hall, so that the function of immediate forecast is not impaired.
一方、割当信号は割当判断後直ちに出力するのではな
く、割当信号の出力タイミングを決定する手段13によっ
てその出力タイミングを決定する（手順M3）。この割当
信号の出力タイミングの決定は、例えば次のようにして
行われる。On the other hand, the allocation signal is not output immediately after the allocation is determined, but its output timing is determined by the means 13 for determining the output timing of the allocation signal (procedure M3). The output timing of this allocation signal is determined, for example, as follows.
まず乗場呼び3Uの割当信号を、いまの時点でＡ号機に送
った場合のＡ号機の評価値（例えば各乗場呼び3Uと4Dの
発生からの予測待時間）を演算する。この演算は手順M1
で行った割当判断と同じ評価値を用いる場合は同じ値と
なるので、手順M1で行った結果を記憶させておいてその
値を用いるようにしてもよい。First, an evaluation value of Unit A when the hall call 3U allocation signal is sent to Unit A at this point (for example, the estimated waiting time from the occurrence of each hall call 3U and 4D) is calculated. This operation is procedure M1
Since the same value is used when the same evaluation value as that used in the allocation determination made in step 1 is used, the result obtained in step M1 may be stored and that value may be used.
次に乗場呼び3Uの割当信号を、遅らせて出力した場合

評価値を演算する。そしてこれら演算で求めた２つの評
価値の差が所定値以上（但し後者の方が評価が良い）の
間は割当信号の出力は見送る（手順M3,M4の繰り返
し）。２つの評価値のうち前者の方が良い場合或いはそ
の差が所定値以下になったときには、割当信号を運行制
御装置へ送る。Next, the evaluation value of the car A when the allocation signal of the hall call 3U is delayed and output (when the car A is sent after passing through the third floor) is calculated. Then, while the difference between the two evaluation values obtained by these calculations is equal to or greater than a predetermined value (however, the latter has better evaluation), the output of the allocation signal is postponed (repeating steps M3 and M4). If the former of the two evaluation values is better, or if the difference between them is less than a predetermined value, an allocation signal is sent to the operation control device.
従って第４図の状態の場合、乗場呼び3Uに対してＡ号機
が選択された時点で、この２つの評価値のうち前者の評
価値の方が良い場合或いはその差が所定値以内の場合
は、直ちに割当信号がＡ号機の運行制御装置20Aに送ら

各呼びに応答する。しかし、Ａ号機が選択された時点で
前述の２つの評価値の差が所定値以上（但し後者の方が
良い）の場合は、乗場呼び3Uの割当信号は運行制御装置
20Aに出力されず、従ってＡ号機は既に割当てられてい

経路で運転が行われる。そしてこの場合は、Ａ号機の運
行制御装置から見れば、Ａ号機はかご呼びと割当てられ
た乗場呼びに対して常にセレコレ方式で運転を行ってい
るが、実際には呼びの状況に応じてより効率の良い経路
で運転を行っていることになる。Therefore, in the case of the state of FIG. 4, when the No. A is selected for the hall call 3U, if the former evaluation value of these two evaluation values is better or the difference is within a predetermined value, Immediately, an assignment signal is sent to the operation control device 20A of the car No. A, and the car No. A responds to each call in the order shown in FIG. However, if the difference between the above two evaluation values is greater than or equal to a predetermined value (however, the latter is better) when Unit A is selected, the allocation signal for the hall call 3U is the operation control device.
No output is made to 20A, and thus Unit A operates to respond to the already assigned hall call 4D, and when Unit A passes the 3rd floor, the hall call 3U assignment signal is transmitted to the operation control unit 20.
It is output to A, and as a result, Unit A operates along the route shown in Fig. 4 (b). In this case, from the operation control device of the Unit A, the Unit A is always operating by the celecole method for the car call and the assigned hall call, but in actuality, depending on the situation of the call, You are driving on an efficient route.
なお、上記の実施例では評価の判断基準に乗場呼びの予
測待時間を用いているが、勿論これに限るものではな
い。Although the predicted waiting time of a hall call is used as a criterion for evaluation in the above embodiment, it is not limited to this.
また上記の実施例では、予報表示信号を運行制御装置へ
出力するようにしているが、予報表示信号を直接乗場の
到着予報灯へ出力するように、すなわち到着予報灯の制
御は群管理装置で行うようにしてもよい。In the above embodiment, the forecast display signal is output to the operation control device, but the forecast display signal is directly output to the arrival forecast light of the landing, that is, the arrival forecast light is controlled by the group management device. It may be performed.
本発明によれば、割当信号と予報表示信号とを分離し、

来のセレコレ方式のままであるにも拘わらず、実際には

ができ、しかも即時予報の機能は活かしたままとするこ
とができる。According to the present invention, the allocation signal and the forecast display signal are separated,
Moreover, since the output timing of the allocation signal is determined according to the call situation, even though the operation control device of each unit is still the conventional celecole system, it actually depends on the call situation. It is possible to drive on a more efficient route and still keep the function of immediate forecasting.
また、各号機の運行制御方式は変更する必要がないの
で、既設現場にも容易に適用することができる。Further, since it is not necessary to change the operation control system of each unit, it can be easily applied to the existing site.
