Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator system and, more particularly, to a configuration of an elevator system suitable for analyzing an operation state of an elevator.

[0002]

2. Description of the Related Art A position indicator has been installed at a landing to inform a user of a position and a traveling direction of an elevator for a long time. At
Position indicators are widely used.

On the other hand, in an elevator system,
In order to achieve high-efficiency operation, in response to a user's request for use, the order of services provided by a single-installed elevator will be determined. An operation control device that performs processing such as deciding whether or not to provide a service using the service is provided.

Particularly in a large-scale building, a group management control device realizes efficient operation of various items such as waiting time, boarding time, congestion degree in a car, and transportation capacity.

[0005] However, in order to operate the entire building with high efficiency, the elevator car arriving first at the floor where the user is located is not always serviced, and the elevators of the entire building may be passed. It may be an unnatural operation for general users who cannot know the usage status.

For this reason, in many elevator systems provided with a group management control device, only a service guide light for notifying a user in advance of an elevator to be serviced is installed without individually displaying an elevator position.

[0007] For the user, the position indicator of the elevator is desirable to be installed because the operation state can be grasped,
On the other hand, it also causes dissatisfaction with unnatural operations such as passing.

As an example of the countermeasure, Japanese Patent Publication No. 56-4398
No. 9 discloses a method of validating only the position indicator of an elevator for which service has been reserved. JP-A-1-192686 discloses an operation schedule display device capable of displaying not only a position display but also a use request status of each floor and various evaluation values used for assignment evaluation.

[0009] On the other hand, if the user complains about the operation of the elevator, the actual operation status of the building is used to investigate whether there is a problem in the operation method, to investigate the cause, and to the user. It is best to give an explanation.

[0010] For this purpose, a device for collecting operation data is required. For example, Japanese Patent Application Laid-Open No. Hei 8-13437 discloses a device for automatically collecting operation data for a specified time.
Japanese Patent No. 2607687 discloses an apparatus for recording not only operation data but also various assignment data used for determining the operation.

[0011]

In the conventional elevator system, at the time of individual use of the elevator users, it is necessary to ask the user about why an elevator car is selected to be serviced in a certain order. There was a lack of consideration to explain.

[0012] Therefore, if there is a problem with the operation of the elevator system, a problem arises up to now, and then the building manager or a maintenance person is contacted, and the maintenance person etc. investigates the problem again. I was

However, in this investigation method, the investigation is not performed on the data at the time of occurrence of the problem, but is performed after the maintenance staff or the like has been contacted. However, there was a problem that the true cause of the problem could not be grasped.

[0014] It is an object of the present invention to provide an easy method for notifying elevator users of operational problems.

It is another object of the present invention to record operation data at the time point when a problem in operation is pointed out, and to provide the data to maintenance personnel and the like.

[0016]

According to the present invention, there is provided an elevator system comprising: an elevator;
Use request receiving means for receiving a use request from an elevator user, operation control means for controlling the operation of the elevator in accordance with the use request from the user, operation recording means for recording the operation state of the elevator, And / or recording instruction means installed in the car and instructing the user to record the operation state.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the system configuration diagram shown in FIG.

The elevator system basically operates in response to an elevator user's use request that occurs at irregular intervals. Can be unsatisfactory and unsatisfactory operation.

In the following description, an elevator system capable of coping with an unsatisfactory operation of a user will be described. In this system, when the elevator user is unsatisfied with the operation of the elevator, there is provided means for transmitting the unsatisfactory information to the elevator system.

In response to a user's expression of dissatisfaction, data of the elevator operation status near the time when the unsatisfactory operation occurs is recorded, thereby facilitating the analysis of the cause of the unsatisfactory operation. Like that.

The operation display 10 is installed at a necessary place in the elevator platform and / or the car 30 and is connected to the operation control device 40 and the car control device 32 to display operation information.

A recording instruction button 11 is provided at a required place in the elevator platform and / or the elevator car 30, and corresponds to a recording instruction means when an elevator user encounters a situation unsatisfactory in elevator operation. The recording instruction button 11 is operated to transmit to the elevator system.

A hall call button 21 corresponding to a use request receiving means is provided at the elevator platform, and a destination floor button 31 is provided in the car 30.

The operation section 41 inside the operation control device 40 executes operation control and display processing 100 (FIG. 4) described later, and further records data relating to the operation as operation record data 43 corresponding to operation recording means. I do.

Here, the operation data includes (a) the position of the car, the traveling direction, the status of registration of the hall call and the destination floor, the number of persons in the car, and (b) the floor and / or stop in the car for which use is requested from the platform. Estimated arrival time and / or estimated car weight of each car and actual value of the time required to actually arrive / actual value of the number of people in the car at arrival on the planned floor (c) The car is in a state where the response to the use request from the platform is restricted, or the car is operating differently depending on the car, during dedicated operation, during maintenance work, on standby, paused, or stopped on each floor ( d) When the recording instruction button 11 is operated, the operation control device
Information indicating the control method, control parameters, effective rule base, or the configuration and weight of the neural network used for operation control used in 40.

When the recording instruction button 11 is operated, the recording control unit 42 records the operation recording data 43 by adding index information indicating the recording instruction time to the operation recording data 43.

The operation record data 43 is provided with a temporary recording unit for repetitively overwriting and using a record in a short cycle, and a permanent recording unit for not erasing the recorded contents unless a specific instruction is given.
When the recording instruction button 11 is operated, the recording control unit 42 copies the data of the operation state within a predetermined time range before and after the operation from the temporary recording unit to the permanent recording unit and records the data. Here, the predetermined time range before and after the operation time point is, for example, data for each 30 minutes before and after the operation time point.

[0028] The use status of the elevator varies daily, and even if some strange operation is performed at a certain point,
Later surveys will not always reproduce the same situation.
Therefore, recording the operation data at the time of the recording instruction can easily analyze the cause of the unsatisfactory operation.

In the present invention, the waiting time is long.
If the user is unsatisfied with the operation, it is sufficient to operate the recording instruction button 11 and it is not necessary to install the operation indicator 10, but it is necessary to check the situation with the operation indicator 10 and pursue the cause. If the user operates the recording instruction button 11 after determining that it is necessary, it is possible to more efficiently grasp the problem. When the operation indicator 10 and the recording instruction button 11 are used together, it is easy to integrally configure them.

The user of the elevator connects to the communication control unit 44 of the operation control device 40 via the in-building network 51 using the user personal computer 52 corresponding to the operation result display means. The operation data at the point instructed is taken out from the operation record data 43 and displayed and referred to the user personal computer 52.

The operation status of the elevator within a predetermined time range at the time when the recording is instructed to the user personal computer 52, the predicted evaluation value used when deciding the operation within this range, and the actual value corresponding to the predicted evaluation value. Are displayed at the same time, it is easy to determine whether the predicted value that is the basis of the operation control of the elevator system is appropriate for the actual value.

When the difference between the predicted evaluation value used at the time of operation decision and the actual value corresponding to the predicted evaluation value is equal to or larger than a predetermined value, the user This is to analyze and display the cause of the difference between the predicted value and the actual value, such as a long-time operation of the open button.

Further, when the recording instruction button 11 is operated, it is effective to notify the maintenance center of the presence / absence of the operation and / or the operating state of the elevator within a predetermined time range at the time when the recording is instructed. In that case, the communication control unit
44, the in-building network 51, the gateway 53, and the external network 61 serve as a means of notifying the maintenance center 62.
