Abstract

PROBLEM TO BE SOLVED: To deal with sudden change of a traffic flow or change of a traffic flow depending on days of the week by providing an operation schedule memory means, and performing preparatory arrangement with prioriy to waiting control. SOLUTION: Information from hall call buttons 101-10n and the generated time of the hall call from a time piece 28 are written on a learning table 23 through a care learning part 21. Information of the hall call buttons 101-10n and information of car call buttons 51 are sent to a coming back learning part 22, and both are compared with each other so as to decide a coming back floor. The coming back floor, a care stand-by floor, a stand-by time computing part 25 discriminate the sorts of data in the learning table. When a learning result for care allocation of cars exists, a command of allocation of cars is sent to an operation control part 27, and when a coming back learning exists, a command of coming back learning is sent to the part 27. A command of preferential allocation of cars based on a forced allocation of cars table 24 is input from a forced allocation of cars computing part 26 to the operation control part 27. Hence, the cars can be efficiently allocated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator operation management device.

[0002]

2. Description of the Related Art A conventional technique of this kind is disclosed in Japanese Unexamined Patent Publication No. 7-2434.
Japanese Patent Laid-Open Publication No. HEI 9-214572 discloses an elevator for a private house, in which a waiting time for a landing is shortened by running the elevator in advance in response to a regularly occurring landing call.

Further, Japanese Patent Application Laid-Open No. Hei 4-133981 discloses a method of predicting a future change in traffic flow using characteristic data of a temporal change in traffic demand and performing dispatch control on a predicted congestion floor.

[0004]

In the prior art, it is possible to learn and predict a hall call, a car call, or a traffic flow, and to move an elevator in advance to a floor where a hall call is predicted to occur, and wait for it. Therefore, it is possible to improve convenience such as shortening the waiting time.

However, in Japanese Patent Laid-Open Publication No. Hei 7-2434, a waiting floor is determined based on only time data, and the system waits. Therefore, the learning result may be incorrect depending on the day of the week.

[0006] In the case of a house, if a new regular elevator user is generated due to replacement of a resident, the previous learning result is incorrect.

An object of the present invention is to provide a rapid change in traffic flow,
The purpose is to enable appropriate prior vehicle allocation even for traffic flows that differ depending on the day of the week.

[0008]

A learning means for learning a time at which a hall call has occurred and a floor, and a predicted occurrence time of a hall call are determined based on a learning result from the learning means. In an elevator including a queuing command creating means for determining a queuing floor and outputting a queuing command, and an operating means for operating the elevator in accordance with the queuing command, the elevator includes an operation schedule storage means, and has a prioritized vehicle allocation prior to the queuing control. Operation management device for an elevator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will now be described with reference to FIGS.
This will be described with reference to FIG.

FIG. 1 is a block diagram showing one embodiment of the present invention.

When the hall call buttons 101 to 10n or the car call button 51 is pressed, the information is sent to the operation control unit 27 in the elevator control device 2, and the hoisting machine 3 is driven to call the car 5. Move to the floor of occurrence and provide services to users.

The information from the hall call buttons 101 to 10n is also sent to the learning unit 21 at the same time, and the learning unit 21 reads the occurrence time of the hall call from the clock 28 and writes the learning result in the learning table 23. In addition, hall button 1
The information of 01 to 10n is sent to the return learning unit 22 together with the information of the car call button 51. The return learning unit 22 determines the floor to be returned by comparing the numbers of the two, and except during off-peak hours when the learning result of the attentive learning unit 21 does not exist,
The result is written in the learning table 23 in a format different from the result of the attentive learning unit 21.

Return floor, attentive standby floor, standby time calculation unit 2
5 discriminates the type of data in the learning table and, when the learning result for the attentive vehicle allocation is included, compares the result with the past learning result and sends a vehicle allocation command to the operation control unit 27. When return learning is included, a return command is sent to the operation control unit 27.

The compulsory dispatch table 24 stores in advance the day of the week, the time, the floor, etc. for distributing cars.
Responds accordingly to the return control, the attentive standby floor, and the dispatch control command which has a higher priority than the command from the standby time calculator 25.
Send to

The operation control unit 27 which has received the above command
Drives the hoisting machine 3 accordingly to move the car 5 to the call generation floor and provide service to the user.

FIG. 2 is a table configuration diagram of the learning table 23. The waiting request table 23 includes a hall call occurrence time 23-A, a waiting request floor 23-B, a discrimination flag 23-C, and a control state 23-D upon returning.

The discrimination flag 23-C indicates whether the data is of the attentive or return type.
The attentive waiting floor / waiting time calculating unit 25 separates the attentive command and the return command.

The control state 23-D at the time of return represents the result after the learning return, and selects the return that opens the door in the upward direction, the return that opens the door in the downward direction, and the return that does not open the door.

[0019]

According to the present invention, in addition to dispatching vehicles by learning control,
By using the operation control for forcibly returning, efficient vehicle allocation can be performed, and a sudden change in traffic flow can be dealt with.
