Abstract

PURPOSE:To improve the service performance by computing/correcting the data table of the expected time of arrival and the expected in-cage crowded condition to calculate the evaluation value of call allocation only in a necessary range according to the changes in the operational condition of an elevator, and renewing the data table into appropriate one. CONSTITUTION:The expected time of arrival until a plurality of elevators arrive at each floor, and the expected in-cage crowded condition of each elevator are calculated respectively, and these respective calculated values are stored in the respective tables. The evaluation value for each number is calculated based on each stored value, and the new hall calling of the specified floor is allotted to either of the elevators according to this calculated value, this change is detected 20, and a judgement is made whether or not the specified condition is generated. As a result, when the specified condition is generated, at least, either of the expected time of arrival and the expected in-cage crowded condition is computed 40 for the specified range 30, and this table is renewed 50.

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.

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.
