DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of the present invention.

The elevator control device 1 receives the hall call buttons 21 to 2n and the car call button 4 of the car 3 and accepts the generation of the car call.
1 sends these signals to the management center 5 in the building or the maintenance management device 8 of the maintenance company 7 via the communication line 6.

The maintenance management device 8 of the management center 5 or the maintenance company 7 receives the signal from the unit communication unit 11 by the management device communication unit 81, performs learning by the learning unit 82 in the maintenance management device 8, and stores it in the learning table 83. Write. The maintenance management device 8 has a clock 84, determines holidays, weekdays, and the like using a calendar and calendar 85 set by the setting device 9, and stores the occurrence times of hall calls and car calls. In the maintenance management device 8, a hall call prediction unit 86 and a predicted hall call generation unit 87 are provided.
Based on the learning result of the learning unit 82, the occurrence time of the hall call, the arrival time of the user, and the like are separately predicted for holidays, weekdays, and the like, and are written in the hall call prediction table 88. The hall call generation unit 87 uses a clock 84 in the maintenance management device 8 based on a hall call prediction table 88 which is a prediction result of the hall call prediction unit 86, and generates a hall call at or before the predicted generation time. A command is sent to the elevator control device 1 using the management device communication unit 81 so as to call the elevator to the floor where the arrival of the vehicle is predicted. The elevator control device 1 causes the elevator to arrive at a floor where a call to the elevator or a user's arrival is expected according to a command.

When the meeting is successful and the door is opened, the hall call button is not pressed even when the user arrives,
Since a hall call does not occur, in this case, learning is performed as if a hall call on the floor where the elevator is located due to the occurrence of a car call.

FIG. 2 is a schematic flowchart of the present invention.

(A) is a flowchart of the learning.
First, when the hall call buttons 21 to 2n are pressed to generate a hall call, the elevator control device 1 detects this (201). The elevator control device 1 includes a car communication unit 1
The information on the occurrence of a hall call is sent to the management center 5 or the maintenance management device 8 of the maintenance company 7 via the server 1 (202). The maintenance management device 8 receives the signal from the unit communication unit 11 by the management device communication unit 81 (203), checks the occurrence time and date by the clock 84 (204), and sets the setting device 9 in advance.
Thus, the learning result is learned in another learning table 83 for holidays, weekdays, specific days, or days of the week in accordance with the individually set calendar or calendar 85. For example, the learning is performed at a certain time, on a certain floor, after the learning on the day, Pij is the probability of occurrence of the hall call, Diij is the occurrence status of the hall call on the day, and Pijold is the probability of the hall call up to the previous day, Pij = (1−
α) Learn as Dij + αPijold. Here, α is called a forgetting coefficient, and takes a value from 0 to 1.

FIG. 2B is an example of a hall call occurrence prediction. First, the hall call occurrence prediction unit 86 sets the learning table 8
Based on the learning result of No. 3, a hall call occurrence prediction for each floor is performed and written to the hall call prediction table 88 (21).
1). Next, the hall call generation section 87 predicts the next hall call based on the hall call prediction table 88.
(212) It is determined whether or not the prediction does not hinder the operation of the other floor and it is highly possible that the user can meet (21).
3) When these are satisfied, the management control device communication unit 81
Is used to send a command to the elevator controller 1 to call the elevator to the hall call occurrence prediction floor (21).
4). The elevator control device 1 calls the elevator to the hall call occurrence predicted floor by, for example, generating a virtual hall call on the hall call generation floor based on the command (21).
5).

The judgment of the occurrence of a hall call is made when the probability of occurrence of a hall call on the own floor is equal to or higher than a predetermined value and the probability of occurrence of a hall call on another adjacent floor is equal to or lower than a predetermined value. Specify within one round of the elevator.

Here, the occurrence of the hall call is predicted sequentially, and the waiting is performed by generating a virtual hall call. However, the hall call for a certain period such as one day is predicted in advance, and the elevator control device is 1 may be transmitted. By doing so, the number of transmissions with the elevator control device 1 can be reduced, which is particularly suitable when a telephone line is used.

FIG. 3 shows an example of the learning table 83.

FIG. 4 shows an example of the hall call prediction table 88. (A) is an example of the case of performing sequential prediction. In this embodiment, less memory is required. (B) is an example of a case in which hall call prediction for a certain period such as one day is performed in advance. In this embodiment, a large amount of memory is required, but it is possible to predict a number of hall calls in advance and transmit them at once.
The number of transmissions to the elevator control device 1 can be reduced.

FIG. 5 shows an example in which a temporary storage table is provided in the elevator control device 1. A temporary storage table 12 is provided in the elevator control device 1, and the internal clock 1
3 temporarily stores the occurrence of a hall call. After learning for a predetermined period such as one day, hall call occurrence information is transmitted from the machine communication unit 11 to the maintenance management device 8.

According to the present embodiment, the number of times of communication from the elevator control device 1 can be reduced, and a system suitable especially when a telephone line is used can be constructed.

Similarly, if a temporary prediction table 14 is provided to receive an occurrence prediction result for a predetermined period, such as one day, and the in-car occurrence prediction unit 15 calls the elevator according to the time of the in-car clock, maintenance is performed. The number of times of communication from the management device 8 can also be reduced.

In this case, the internal clock 13 transmits the current time when the occurrence prediction result is transmitted from the maintenance management device 8 and also performs the clock adjustment, so that more efficient transmission can be realized. .

FIG. 6 shows an example of a calendar and a calendar when a calendar and a calendar are provided for each floor. If a calendar and a calendar are provided for each floor in this manner, different tenants are entered for each floor, and accurate learning can be performed even when holidays are different.

[0026]

According to the present invention, the hall call can be learned at the management center or the maintenance company of the maintenance company, so that it is only necessary to set the clock of the maintenance system.
In addition, different calendars and calendars can be easily set for each elevator, and more practical learning can be performed. In addition, the maintenance management device of the management center or the maintenance company has less restrictions on the memory and the like than the elevator control device, so that it is possible to perform detailed learning using a larger amount of memory, and according to the learning situation, It is also possible to specify whether or not to wait for an elevator at each floor, and furthermore, it is possible to learn with a different calendar for each floor, so that even when a different tenant enters each floor, an accurate waiting can be performed.
