方法があった。2. Description of the Related Art Conventionally, calculation of an elevator arrival time prediction for hall call assignment control of a group management elevator is disclosed in Japanese Examined Patent Publication No. 55-17746.
For each floor regardless of whether there is a hall call, the estimated arrival time is calculated by taking into consideration the number of stops until arrival, the floor position of the elevator, the number of passengers waiting in the hall, and the number of passengers by floor on the floor of the car No. 62-7107 is disclosed.
There has been a method of calculating an estimated arrival time by a task activated in a certain cycle, obtaining an evaluation value for each call, and allocating a new hall call or reallocating an already assigned hall call.

多いため処理時間が遅くなり、制御上の問題が生じる。In the above-mentioned prior art, the estimated arrival time is calculated for every fixed period.
Inappropriate elevators may be selected if call assignments occur immediately after an event that causes a significant change in arrival time. For example, the estimated stop time of the elevator is the shortest just before passing a certain floor, but is the maximum since it is after one round immediately after passing. In such a case, in the conventional method, the estimated arrival time is calculated in a fixed cycle, and therefore, when the hall call allocation evaluation is performed immediately after passing by the value calculated immediately before passing, the farthest from the stop floor. A problem occurs such that an elevator is assigned. If the cycle of calculating the estimated arrival time is shortened in order to prevent such a situation, the processing time is delayed due to the large amount of calculation, which causes a control problem.

It is detected at 20 whether the elevator position signal 10 of the floor position signal, the car call registration signal, the new hall call assignment signal, the hall call assignment signal, and the driving direction signal has changed. When the change detection 20 detects that one of the signals has changed, the update range is set at 30 for the number of units, floor range and running direction that were in the changed event. The predicted arrival time and the predicted in-car congestion degree in the set range are corrected and calculated in the calculation processing of 40, and the respective data tables are updated with 50 from the result.

Of the multiple elevators on the floor, this is Unit A. Now, it is assumed that the stoppable floor of the elevator A, which is traveling in the descending direction, changes from the 9th floor of 21a to the 8th floor of 21b. At this time, it becomes impossible to stop the correction calculation range, and after the arrival has completed one round, from the 9th floor to the 1st floor
The portion indicated by the thick line in the estimated arrival time table 22a in the descending direction in which the value calculated by the normal arithmetic processing is stored as the descending direction which is the same as the traveling direction to the floor is updated. As the calculation process, for example, regarding the passing floor,
A normal operation is performed by calculating the arrival prediction time of the floor that has passed immediately before the normal operation processing, in this case, the estimated arrival time of the 10th floor, that is, a value C ′ obtained by adding 10 seconds to the maximum value C in the arrival prediction time. It is set in the data table of the floor that cannot be stopped after the operation, in this case, the ninth floor. For the following 8th floor to 1st floor, the floors are set to be shifted by 1st floor like D to K of 22b.

At this time, the range in which the correction calculation is performed is the portion indicated by the bold line in the estimated arrival time table 33a from the floor below the call-allocated sixth floor to the end floor in the traveling direction in the descending direction. The calculation method is to obtain original data H to L by taking into account the time to stop at the hall call, and obtain a predetermined value, for example, the value of H'to L'to which 15 seconds are added respectively, and to obtain Table 3
Update as shown in 3b. The predicted car congestion degree table 34 is also updated to the same range of data, k-shi, by the number of passengers determined in advance according to the traffic demand, for example, values k'-shi 'obtained by adding two people.

First, with respect to the car No. A, the range in which the correction calculation is performed is HL from below the floor to which the hall call was initially assigned to the end floor in the traveling direction. The calculation method is H ′ to which a predetermined stop time, for example, 15 seconds is subtracted from the original data.
Update to L '. For Unit B, this is the same as when assigning a new hall call.

た値P,Oとする。FIG. 4 shows an example of the case where the elevator No. A 41a, which was traveling in the descending direction, did not go to the end floor but was turned over after receiving the final call on the 4th floor, 41b. In this case, the predicted arrival time J of the third floor is the minimum before the direction reversal, but becomes the maximum after the direction reversal. Therefore, in order to prevent calls from the third floor to the first floor from being assigned in the traveling direction before the direction is reversed, the estimated arrival time table 42 in this range is based on the estimated arrival time after one round in advance. Set the values X to Z defined in. Contrary to J, the estimated arrival time H, which was the maximum before the direction reversal, becomes the minimum after the direction reversal. Therefore, for the floors in the traveling direction after the direction is reversed, the range of floors that can be moved within the maximum time range of the cycle in which the normal calculation is performed, for example, the table 42 for H and G of the front two floors.
Update. However, if there is a call in that area, it will be up to the floor where the call is made. The values to be updated are predetermined values P and O based on the estimated arrival time obtained by the normal arithmetic processing.
