DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 FIGS. 1 and 2 show an embodiment of the first to sixth aspects of the present invention. FIG. 1 is an overall configuration diagram, and FIG. 2 is an operation flowchart. In FIG. 1, reference numeral 1 denotes a landing button installed at a landing of an elevator on each floor, and 2 denotes a control installed in a machine room for registering a landing call by operating the landing button 1 and controlling the elevator to respond to the landing call. The panel 3 is a hoist that drives the elevator based on an operation command from the control panel 2.

Reference numeral 4 denotes a main rope driven by the hoist 3,
A car 5 is connected to one end and a counterweight 6 is connected to the other end. Reference numeral 7 denotes a vehicle dispatching device connected to the control panel 2 and configured by a computer and configured to automatically dispatch the car 5; 8 denotes a clock device connected to the vehicle dispatching device 7 and outputs the current date and time; 9 denotes a vehicle dispatching device 7
Is a storage device for recording the occurrence status of a hall call.

When the hall button 1 is pressed at the hall, a call signal (up call or down call) is sent to the control panel 2 and the hall call is registered. The control panel 2 determines the driving direction of the car 5 from information such as the direction of the hall call and the position of the car 5, activates the hoisting machine 3, and causes the car 5 to travel. And
When car 5 approaches the floor where the hall call is registered, car 5
Slow down to stop on the floor and open the door. Since these operations are well known, detailed description is omitted.

Next, the operation of this embodiment will be described with reference to FIG. In step S1, the car 5 is in normal operation (fully automatic operation). In step S2, it is determined whether the current time is a flexible park mode set time (hereinafter, referred to as a mode set time). Here, the flexible park mode refers to a mode in which the emptied car 5 is made to wait at any time by judging the optimum park floor from the hall use history. In step S2, the set time recorded in the storage device 9 by the vehicle allocation device 7 is compared with the current time output from the clock device 8 to determine whether the mode set time has arrived.

Note that the mode setting time and the park floor change unit time (see step S10) are registered in the storage device 9 such as "from Monday to Friday, from 7:00 am to 9:00 am" and "5 minute intervals". . Except for the mode setting time, it is in a so-called "drop-off" state in which the car 5 waits on the floor where the car 5 is emptied as before. Here, if the mode setting time has not arrived, the process proceeds to step S12, and if it has, the process proceeds to step S3.

In step S3, the vehicle allocation device 7 stores the storage device 9
, The hall call occurrence status history (for each floor, for each day of the week, for each floor) recorded in the same time zone is checked, and a floor having a call history of a predetermined number of times or more is flagged as a park candidate floor.
In step S4, the vehicle allocation device 7 sets the optimum park floor from the floor for which the flag is set in step S3 based on the hall call occurrence status history recorded in the storage device 9, and causes the car 5 to wait.

An example of setting the optimum park floor is shown below. (1) A coefficient is set in advance for each hall, and the number of times of call generation in the same time zone in the past is multiplied by the above coefficient, and the value is evaluated, for example, in 10 steps. This coefficient is, for example, an upper floor for a down call, a lower floor for an up call,
Each floor is weighted by increasing the coefficient such as the floor used by the important customer. (2) The highest evaluation floor in the evaluation result of (1) is set as the optimum park floor. (3) When a plurality of optimal park floors occur, (A) a floor close to the current stop floor, (B) a floor with a large setting coefficient when it is at the same distance from the current stop floor, and (C) a coefficient with the same Are set in the order of the upper floor. (4) If there is no floor on which the flag is set, "drop off".

In step S5, while the car 5 is waiting at the optimum park floor, it is determined whether a hall call has occurred. If the hall call does not occur, the process jumps to step S10, and returns to step S4 to select the optimum park floor again unless it is time to change the park floor. If the hall call of the selected optimum park floor has not occurred, the same floor is naturally selected and the waiting is continued. If a hall call occurs, the process proceeds to step S6, and the generation of the hall call is registered in the storage device 9. In step S7, it is determined whether a flag is set on the floor where the hall call has occurred.
If the flag has not been set, the process jumps to step S9. If the flag has been set, the process proceeds to step S8. In this time zone, the flag is reset so as not to become a park candidate floor thereafter.

In step S9, a response is made to the hall call by normal operation. In step S10, it is determined whether or not the park floor change time (for example, every 5 minutes) has elapsed. If the elapsed time has not elapsed, the process returns to step S4, and the optimum park floor (the second-ranked floor) is selected from the floors on which the remaining flags are set, and the flexible park mode is continued. If a hall call occurs on another floor during standby,
Release the flag for that floor and change the ranking at any time.
If the park floor change time has elapsed, the process proceeds to step S11, and the hall call history frequency in the same time zone on the floor where the flag is set is reduced by a certain number.

This means that the estimation of the occurrence of a hall call has been missed, and this is to deal with a case where a user is absent due to relocation or the like, and there are no users in the same time zone. Then, after releasing the flag, the process returns to step S2 to determine whether to continue the flexible park mode. If it is determined in step S2 that the time is outside the mode setting time, the process proceeds to step S12, and it is determined whether a hall call has occurred. If no hall call occurs, step S15
If a hall call occurs, the process proceeds to step S13.

In step S13, the occurrence of a hall call is registered in the storage device 9. In step S14, a response is made to the hall call by normal operation. Then, the process stands by at the stop floor in step S15, and returns to step S2. Step S
Steps 12 to S15 are normal "drop-off" operations. However,
Thereafter, when the flexible mode is set, the hall call occurrence status is registered in the storage device 9 in step S13 so as to be able to respond immediately.

Here, step S2 constitutes a park mode time zone setting means, which makes it possible to exclude a daytime or the like where an accidental landing call is likely to occur from the target. Unnecessary park operation can be suppressed. Further, the capacity of the storage device 9 can be saved. Step S3 constitutes a park candidate floor selecting means. By setting a flag only on floors where a hall call has occurred more than a set number of times on the same day and the same time period in the past, an accidental hall call that occurred in the past is set. It is possible to suppress the useless park operation with respect to.

Step S4 constitutes an optimum park floor waiting means and a waiting means, based on the history of hall calls among the candidate park floors, that is, the number obtained by multiplying the number of occurrences of past hall calls and the set coefficient. By selecting the optimal park floor, it is possible to make the car stand by on the floor for one individual such as an important customer, and it is possible to make the car particularly suitable for an elevator for small and medium-sized buildings.

Step S8 constitutes a candidate park floor canceling means. If the car has a waiting hall call on the optimum park floor and the floor on which this hall call has occurred is selected as the candidate park floor. By releasing the floor from the candidate park floor, the next candidate park floor can be set as a more suitable floor. When a hall call occurs on another floor during standby, the flag of that floor is released, and the rank of the park floor can be changed.

Step S11 constitutes a history frequency changing means. When the park floor change time comes, the evaluation frequency of the hall call history of the selected candidate park floor at that time is reduced by a certain number. For example, when the user's attendance time is changed, it is possible to recognize that the use has disappeared, lower the ranking, and always select the optimum park floor.

[0026]

As described above, according to the first aspect of the present invention, when a car responding to a hall call becomes an empty car, the car is made to wait at the optimum park floor selected based on the history of hall calls. The car can be made to stand by on the floor relating to one individual such as an important customer, and can be particularly suitable for an elevator for small and medium-sized buildings.

Further, in the second invention, the park mode time zone in which the standby operation to the optimum park floor is executed is set, so that the time zone such as daytime where accidental hall calls are likely to occur is excluded, and The useless park operation due to the detachment can be suppressed.

Further, in the third invention, the floor on which the hall call has occurred more than the set number of times in the past on the same day of the week and the same time period is selected as the park candidate floor. A useless park operation for the hall call can be suppressed.

According to the fourth aspect of the present invention, the optimum park floor is selected from the park candidate floors based on the number of occurrences of past hall calls and the coefficient multiplied by an arbitrarily set coefficient. A car can be placed on the floor for one individual.

According to the fifth aspect of the present invention, if a waiting hall call occurs on the optimum park floor of the car and the floor on which the hall call occurs is selected as a candidate park floor, that floor is released from the candidate park floor. Therefore, the next park candidate floor can be set to a more suitable floor.

Further, in the sixth invention, when a predetermined time elapses after the time enters the park mode time zone, the evaluation frequency of the hall call history of the park candidate floor selected at that time is reduced by a certain number. Therefore, when the user's attendance time is changed, the ranking is lowered, and the optimum park floor can always be selected.
