この発明は、エレベータの速度管理装置に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator speed management device.
従来、複数台のエレベータのかごが並設された

スさせる方式である。 Conventionally, group management has been performed in buildings where multiple elevator cars are installed side by side, with emphasis placed on service to customers waiting at the hall. One of them is the allocation method. This predicts the service status (for example, waiting time) for each hall call, calculates the evaluation value for the service status (for example, the sum of predicted waiting times for hall calls), and assigns the hall call to the car with the minimum evaluation value for the service status. allocation,
This is a system in which only the assigned cars are given a hall call service.
しかし、近年社会的にもネルギ節約の気運が高
まつてきて乗場待客へのサービスの充実及び消費
電力量の節約という二つの要求を満たす群管理エ
レベータが望まれるようになつた。 However, in recent years, there has been a growing trend in society to save energy, and a group control elevator that satisfies the two demands of providing enhanced service to passengers waiting at the hall and saving power consumption has become desirable.
そこで最近は、建物全体のサービス状況（例え

のサービス状況に応じて省電力運転を行なうべき
かご台数を指定し、指定された台数のかごの速度
（加速度、最高速度）を通常より下げることによ
つて省電力運転を行なうことが提案されている。 Therefore, recently, the service status of the entire building (for example, the number of long waiting hall calls) is monitored, and the number of cars that should be operated in power-saving mode is specified according to the service status. It has been proposed to perform power-saving operation by lowering the speed (acceleration, maximum speed) from normal.

る欠点があつた。 However, in the conventional method, a specified number of cars are selected as power-saving operation cars in a preset order such as No. 1, No. 2, etc., so the selected cars are assigned many cars. If you have a different hall call or car call, you may have to wait for a long time for the assigned hall call.
The boarding time for passengers in the car to arrive at their destination floor becomes longer, and in a system where the car to be serviced is displayed in advance to passengers waiting at the landing (hereinafter referred to as a forecast), other cars that have not been predicted arrive first. (hereinafter referred to as "forecast failure"), which had the disadvantage of causing service problems due to driving at a slower speed than normal.

し指令発生装置である。 In the figure, 47 is a minimum value selection circuit, and only when the input signal at point T is "H", the input signal at points Ga to Gd corresponding to keys a to d, respectively, is "L". From among them, select one car for which the input signals of points Ia to Id corresponding to cars a to d, that is, the selection order evaluation value signals 3a to 3d, are the minimum (if there are multiple cars with the minimum value, select (For example, Cart a → Cart B → Cart C → Cart d.) and select Pa to Pd corresponding to Carts a to d, respectively.
Selection signals 47a to 47d are output from the points. In addition, among the selection signals 47a to 47b, only the signal corresponding to the car having the minimum value is "H", and the other signals are "L".
becomes. Moreover, if the input signals of points Ga to Gd are all "H", the selection signals 47a to 47 of points Pa to Pd
All selection signals 47a to 47d also become "L" when the input signal at point T is "L". 48 to 51 have "H" on the S side
When this signal is input, the memory content is reset to "H", and when the "H" signal is input to the R side, the memory content is reset to "L" even if the input signal on the S side is "H". 52 is a counting circuit that counts the input signal that is "H", that is, the output signal from the memories 48 to 51, and outputs it as a counting signal 52m;
53 is the input signal at point X, that is, the count signal 52m is Y
When the input signal at the point is smaller than the power-saving operation number signal 1m, the comparison signal 53m is output from the Z point as "H", and when the input signal at the X point is greater than or equal to the input signal at the Y point, the comparison signal 53m is output from the Z point. 54 is a review command generation device consisting of a comparator that outputs "L" and a pulse generator that generates a pulse signal 54m as shown in FIG. 4 at a constant period T 1 (for example, T 1 = 10 seconds). .

が２台と設定されているとする。 The power-saving operation number setting device 1 that sets the number of cars that should perform power-saving operation according to the service status of hall calls is already known, and although a detailed explanation will be omitted, for example, the power-saving operation number setting device 1 that sets the number of cars that should perform power-saving operation according to the service status of hall calls is already known. If there is no hall call with a duration of 30 seconds or more, the number of power-saving operating vehicles 1m will be increased by one, and if two or more hall calls with a duration of 40 seconds or more occur, the number of power-saving operating vehicles 1m will be decreased by one. It is something that makes you

とになる。 The expected arrival time calculating device 9 is constructed using a known method, so a detailed explanation will be omitted. The expected arrival time is calculated by cumulatively adding up according to the order in which the cars are serviced.In the case of car A, the expected arrival time signal 11U until the first floor up call is answered is based on the fact that there are two car calls on the way. Since the number of floors traveled is 3, the output is 2 x 10 + 3 x 2 = 26 seconds. If 10 seconds have passed since the first floor up call was registered, the duration signal 21U is 10 seconds, and the adder 37
Therefore, 26+10=36 seconds is inputted to point I of the gate circuit 38 as the output signal. Since the first floor up call is assigned to car a, the assignment signal 41U
is "H", so the input signal at point I of the gate circuit 38 is output as is, and the expected time signal 31U is 36
Seconds will be output. Since car a is not assigned to any other hall call, the other predicted waiting time signals 32U to 35U and 36D to 32D are all output as zero seconds, and the maximum value selection circuit 39 selects the selection order evaluation value signal. 3a will be set to 36 seconds.

いことになる。 The selection order setting device 3 now outputs the selection order evaluation value signals 3a to 3d for the cars a to d for 36 seconds and 10 seconds, respectively.
Assume that seconds, 20 seconds, and zero seconds are being output, and the contents of the memories 48 to 51 have just been reset to "L" by the pulse signal 57m. Now, the power-saving operation car signals 4a to 4d all become "L", so the counting circuit 52 outputs the counting signal 52m as zero, and the minimum value selection circuit 47
“L” signals are input to all points Ga to Gd. Also, the comparator 53 determines that X(=0)<Y(=
2) Therefore, the comparison signal 53m becomes "H", and the "H" signal is input to the T point of the minimum value selection circuit 47. Therefore, the minimum value selection circuit 47 selects Ga to Gd.
The car where the input signal at the point is “L”, that is, the car a~
The car d is selected as the lowest car among the selection order evaluation value signals 3a to 3d from the selection signal 47d.
becomes "H". Therefore, the memory 51 is set to "H", the power-saving operation car signal 4d changes from "L" to "H", and the count signal 52m changes from zero to one car. However, the number of power-saving operation units is still 2 with a 1m signal.
Since it does not reach the table, the comparison signal 53m remains at "H". In the minimum value selection circuit 47, a new "H" signal is input to the Gd point, so this time the car a~
The smallest car of the selection order evaluation value signals 3a to 3c, that is, the car b, is selected from c, and the selection signal 47b becomes "H". Therefore, memory 49
is set to "H", the power-saving operation car signal 4b becomes "H", and since there are two count signals 52m, the comparison signal 53m by the comparator 53 becomes "L" for the first time. In the minimum value selection circuit 47, the input signal at the T point becomes "L", so that the number of units in the power saving operation number signal 1m increases or the memories 48 to 51 are reset by the pulse signal 54m. The car with the new minimum value will not be selected.
このようにして省電力運転かごに選択されたか
ごｂ及びｄは、速度管理装置６及び８において、
最高速度を120ｍ／分に制限され運転される。 Cars b and d selected as power-saving operation cars in this way are controlled by speed management devices 6 and 8.
The maximum speed is limited to 120m/min.

が可能となつた。 In this way, when the number of cars that should perform power-saving operation is specified, the specified number of cars that should be operated in power-saving manner By selecting , it has become possible to reduce the occurrence of long waiting times.

そう少なくすることが可能となつた。 In addition, the pulse signal 54m periodically cancels the previous designation of the power-saving operation car, and at that point, the cars to be operated in power-saving operation are reselected in order starting from the car with the smallest maximum predicted waiting time. As a result, even if there are large changes in the conditions of cars or landing areas, the system can sufficiently follow the changes, making it possible to significantly reduce the occurrence of long waiting times.

様の効果が得られることは言うまでもない。 In the above embodiment, in the selection ranking device 3, the maximum predicted waiting time of the assigned hall call is determined for each car, and the car with the minimum predicted waiting time is selected as the power-saving operation car. Although the selection order evaluation value signals 3a to 3d are set as shown in FIG. For each case, evaluate the selection ranking by calculating (a) the total sum of predicted waiting times, (b) the sum of squares (or sum of cubes, sum of squares, etc.) of predicted waiting times, (c) average value of predicted waiting times, etc. May be used as a value. It goes without saying that the same effect can be obtained by using the duration of a hall call or the number of assigned hall calls instead of the predicted waiting time for a hall call.

を選択することができる。 In addition, in the above embodiment, the selection ranking evaluation value was set using the predicted waiting time of the hall call in order to avoid long waiting time. (e) Predicted registration time of car calls for each car (predicted value of time from when a car call is registered until the car responds, the duration of the car call and predicted arrival at the car call floor) (F) Using the number of car calls for each car or the number of passengers in the car,
The selection order evaluation value may be set in the same manner as the predicted waiting time (maximum value, summation, sum of squares, average value, etc.). In this case, a power-saving car can be selected so that the boarding time of the passengers in the car (the time from when they board the car to when they arrive at their destination floor) does not become long.

よい。 Furthermore, in the method of predicting the car to be serviced to passengers waiting at the landing before the car arrives, and in the method of displaying the predicted time until the car will arrive at the landing (waiting time display method), the speed is reduced from normal. By driving according to the system, it is possible to predict the possibility that the forecast will be missed or that the car will not arrive within the displayed waiting time, and the number of hall calls with a high probability as described above will be used as the selection ranking evaluation value. You can also set this to reduce the number of forecast errors and ensure that your car arrives on time. Alternatively, the combination selection ranking evaluation value may be set by weighting the evaluation values regarding the waiting time for a hall call, the boarding time of passengers in the car, and the like.
