Description

  Embodiments described herein relate generally to an elevator motion reproduction system.

  When an abnormality or malfunction occurs in the operation of the elevator, an error code and failure information are recorded in the elevator control device, and the cause of the failure is often found by analyzing these information. The testimony of the user who actually saw the abnormal operation of the elevator may also be helpful in investigating the cause.

  In recent years, a system that determines the cause of an abnormality from application records of an elevator by applying AI technology has also been employed (for example, Patent Document 1).

JP 2009-227401 A

  However, even if the error code log is analyzed, it may be difficult to investigate the cause of the abnormal operation. In this case, there is a possibility that the abnormal operation estimated from the error code is different from the actual operation when the abnormality occurs.

  Further, in investigating the cause relying on the error code, there is a particular problem when there is a report about an abnormal operation from the elevator user, and there is no error code or failure information log remaining. In that case, the user's testimony itself is inaccurate, and there are cases in which the cause cannot be investigated because there are misidentifications and misunderstandings.

Hereinafter, an embodiment of an elevator operation restriction system according to the present invention will be described with reference to the accompanying drawings.
(First embodiment)
An elevator operation reproduction system according to a first embodiment of the present invention will be described with reference to FIGS. 1 and 2.
FIG. 1 is a diagram showing an outline of an operation reproduction system according to the first embodiment. Reference numeral 1 indicates an elevator car, and reference numeral 3 indicates a door (including a car door and a landing door). A car operation panel 2 is provided in the car room of the car 1. On the other hand, a landing indicator 4 is installed at the landing.
The elevator is controlled by the control panel 5. To get on the car 1, the user first presses the hall call button on the hall indicator 4. When the hall call is registered, the control panel 5 instructs the driving unit of the hoist to direct the car 1 to the hall call hall registered.

  When the car 1 arrives at the landing, a landing signal is sent to the control panel 5 from the landing switch. The control panel 5 sends a door opening command to the door motor, and the door 3 opens. When the user gets into the car 1 and presses the button on the destination floor on the car operation panel 2, the car 1 is directed to the destination floor after the door 3 is closed by a command from the control board 5. When the car 1 reaches the destination floor in this way, a landing signal is sent to the control panel 5, the control panel 5 sends a door opening command to the door motor, and the passenger gets off from the opened door 3 to the landing on the destination floor. Can do. Thereafter, the door 3 is closed by a door closing signal from the control panel 5, and the car 1 responds to the next hall call.

In the series of elevator operations from when the passenger calls the car 1 to the destination floor, there are various commands, signals, and information exchanges. Information on these commands and signals includes the following.
First, in FIG. 1, an operation command is issued to various devices of the elevator by executing a control program in an elevator control device provided in the control panel 5 to perform a series of operations. Specifically, the operation commands issued from the control panel 5 to each unit include exchange commands such as a response command to the hall call, a move command to the destination floor, and an open / close command to the door 3. Each unit that receives the command returns a response to the elevator control device of the control panel 5. These exchanges are information directly related to the operation state of the elevator, and are referred to as operation information A.
As a distinction from the operation information A, there is an operation record B sent from each part of the elevator. The operation record B is recorded at various places in the elevator such as hoisting machine, speed governor, door motor, car operation panel 2, landing indicator 4, door 3 safety device, car lighting device, car air conditioner, landing switch at each landing, etc. This is information that is fed back as to how various devices provided perform operations.

  For example, in the case of a hoisting machine, it is information such as when the hoisting machine motor is started up, how many revolutions it is rotated, what is the current value, and when it stops. In the case of the car operation panel 2 and the hall indicator 4, it is information such as when and what kind of car call registration and hall call registration signals have been issued. In the case of switches such as a landing switch, the information is when the switch is turned on / off. If it is a safety device, it is information on when the detector is turned on and when the safety device is not activated. These operation records B are recorded in a time series order in a series of elevator operation processes.

  As shown in FIG. 1, the operation record B is transmitted to the operation reproduction device 6. Among the operation records B, a specific operation record C necessary for reproducing the operation of the elevator is sent to the control panel 5. A series of records of the exchange of the motion information A is transmitted to the motion reproduction device 6 as the motion information record D.

Here, FIG. 2 is a block configuration diagram of the motion reproduction device 6.
The motion reproduction device 6 stores an operation reproduction control device 10 that controls a series of input / output processes for operation reproduction, a recording device 12 that records the operation record B and the operation information record D on a storage medium, and these pieces of information. And a storage device 14 such as a memory or a hard disk.

Therefore, the operation and effect of elevator operation reproduction by the operation reproduction device 6 will be described in more detail.
Here, for example, a situation is considered in which the user has contacted the door 3 when the elevator car 1 arrives at the first floor landing. When the elevator administrator examines it, it is assumed that there is no log of error data in the corresponding elevator, and as long as the error data is seen, there is no evidence of failure. Even in such a situation, as an elevator administrator, there are users who have seen the occurrence of a failure, so it cannot be said that there was no failure, and it is necessary to identify the actual state of the failure and its cause .

Therefore, using the operation information B recorded by the operation reproduction device 6, the elevator reproduction operation is performed as follows to cause the elevator to actually reproduce the defective operation.
In this embodiment, in the elevator that is considered to have failed, all the operation records B during operation are stored in the storage device 14 of the operation reproduction device 6 in time series. Since it is possible to specify the time zone on the day when the failure is thought to have occurred from the user's testimony, the operation record for the time zone (specific operation record C) is sufficient among the recorded operation records B. It is.

  Therefore, the motion reproduction control device 10 reads the specific motion record C recorded in the corresponding time zone and transmits it to the control panel 5 of the corresponding machine. The control panel 5 has a reproduction operation command function for generating an operation command based on the specific operation record C. Each record of the specific operation record C is the result of the operation of each device, and the operation and the result correspond one-to-one, so that the operation can be grasped from the result. Since the operation records are in chronological order, the sequence of each operation record is converted into a series of operation commands, and the operation command is transmitted to the corresponding machine. The reproduction operation can be repeated. In this way, the unit that is considered to have failed can faithfully reproduce the operation at the time of the past failure.

The maintenance staff at the site can investigate while actually observing the operation state of each equipment of the elevator during the reproduction operation, so that the actual state and cause of the failure can be easily clarified.
In the case of this embodiment, the actual situation of the failure that the door 3 may not close can be confirmed, and the cause is specified that the photoelectric tube used in the safety device reacts when the door is closed and does not close. It was done. As a result, the phototube was immediately inspected, and the problem of opening and closing the door could be solved by replacing the phototube.

(Second Embodiment)
Next, an elevator operation reproduction system according to a second embodiment of the present invention will be described with reference to FIGS.

The second embodiment is the same as the first embodiment in that the operation information B recorded by the operation reproduction device 6 is used to perform the reproduction operation of the elevator. In FIG. 3, the same components as in FIG. Are denoted by the same reference numerals, and detailed description thereof is omitted.
The difference from the first embodiment is that the reproduction operation is performed by an elevator of another Unit B at the same hall, not the Unit A that is considered to be defective.

  The situation of the malfunction here is, for example, a situation in which the user has notified that the door 3 is not closed and cannot move after the elevator of the elevator of Unit A arrives at the landing on the first floor.

  In such a situation, it may be impossible to reproduce the elevator operation at the time of failure. For example, it is the case that Unit A failed due to another cause and stopped moving, or it was inspecting. Therefore, in the second embodiment, the operation record B recorded by the operation reproduction device 6 is used to perform the reproduction operation in the elevator of another Unit B as follows, and the malfunction operation is actually reproduced in the elevator. Let

  In FIG. 3, the operation reproduction control device 10 reads the specific operation record C of the No. A machine recorded in the corresponding time zone in which a failure has occurred, and transmits it to the control panel 5 b of another No. B machine. The control panel 5b has a reproduction operation command function for generating an operation command based on the specific operation record C, and transmits the operation command to the No. B machine. In this way, the operation at the time of the occurrence of the past failure can be faithfully reproduced in place of the machine A that is not malfunctioning but is malfunctioning and does not move. Maintenance personnel in the field can investigate the state of the operation of each elevator device that is being reproduced in Unit B instead of Unit A, which does not move, so that the actual cause and cause of the failure can be easily clarified. Can do.

  In the operation reproduction of this embodiment, a log of error data corresponding to the error item set in the control panel is found instead of the investigation of the cause of the failure, not a typical or serious failure that can be clearly understood. The purpose is to investigate the cause of defects that do not remain. In this embodiment, such obvious defects may not be handled. The presence / absence of error data may be used as a criterion for whether or not reproduction operation is possible.

  In the case of this embodiment, it is clear that there is a problem because the elevator has stopped moving, but the cause is specified that the photoelectric tube used in the safety device reacts when the door is closed and does not close It was done. As a result, the photoelectric tube of the safety device of Unit A was immediately inspected, the malfunction of the door opening and closing was corrected by replacing the photoelectric tube, and Unit A was restored.

(Third embodiment)
Next, an elevator motion reproduction system according to a third embodiment of the present invention will be described with reference to FIG.
The second embodiment is also similar to the first embodiment and the second embodiment in that the operation record B recorded by the operation reproduction device 6 is used to perform the elevator reproduction operation. The same reference numerals are assigned to the same components as those in FIG.

The third embodiment differs from the first embodiment in that the reproduction operation is performed by the operation check terminal device 20 in the monitoring center, not the elevator of the actual machine that is considered to be defective.
The operation check terminal device 20 is a terminal device such as a personal computer or a tablet in which simulation software for displaying the operation of the elevator on a monitor is displayed on the monitor based on the operation record of the elevator that is considered to have malfunctioned. The operation check terminal device 20 is connected to the operation reproduction device 6 through an Internet line.

  The situation of the malfunction of the elevator in the third embodiment is, for example, a situation in which the user has notified that the door has not been closed and moved after reaching the landing on the first floor. In addition, there is a situation in which maintenance personnel go to the site immediately and cannot reproduce the malfunction operation.

  Therefore, in the third embodiment, by using the operation record B recorded by the operation reproduction device 6, the operation confirmation terminal device 20 performs the reproduction operation of the elevator as follows, and the malfunction operation is virtually performed on the elevator. to recreate.

  In FIG. 4, the operation reproduction device 6 transmits the specific operation record C of the elevator recorded in the corresponding time zone in which the failure occurs to the operation confirmation terminal device 20 instead of the control panel 5. The reproduction operation is repeatedly displayed on the monitor of the operation check terminal device 20. In this way, it is possible to faithfully reproduce the elevator operation at the time of occurrence of a past failure even if it is virtual without going to the site.

  The administrator in the monitoring center can investigate while looking at the operation status of each device of the elevator that is being reproduced displayed on the monitor of the operation confirmation terminal device 20, so that the substance and cause of the failure can be easily clarified. it can.

(Fourth embodiment)
Next, an elevator motion reproduction system according to a fourth embodiment of the present invention will be described with reference to FIG.
The fourth embodiment is the same as the first to third embodiments in that the operation reproduction B recorded by the operation reproduction device 6 is used to perform the elevator reproduction operation. FIG. The same reference numerals are assigned to the same components as those in FIG.

  The fourth embodiment differs from the third embodiment in that a video camera 22 is installed in the car room of the car 1. Video data captured by the video camera 22 is transmitted to the motion reproduction device 6 together with the motion record B, and stored in the storage device 14. The video can be displayed and viewed on the monitor 24 of the video playback device installed in the monitoring center.

  The situation of the malfunction of the elevator in the fourth embodiment is, for example, a situation in which the user has notified that the door has not been closed and moved after reaching the landing on the first floor. In this case, as in the first to third embodiments, the elevator reproduction operation was performed on the actual machine or the operation check terminal device 20, and it was clarified that the photoelectric tube of the door safety device was functioning. The reason why the photoelectric tube is functioning, whether it is due to an artificial factor, or because of a physical failure has not been identified.

  Therefore, in the fourth embodiment, the video of the time zone in which the malfunction occurred is reproduced on the monitor 24 from the video captured by the video camera 22, and the cause is searched.

  As a result of playing the video in the car room, for example, the door did not close in the evening, and the phototube of the safety device reacted on the inserted west, and it was possible to specify that the door could not be closed. In this case, since the safety device itself was not broken, it was dealt with by taking measures against West Japan.

(Other variations)
Next, a modification of the elevator operation reproduction system of the present invention will be described.
In the first to fourth embodiments described above, during the operation of the elevator, the operation record B is recorded by the operation reproduction device 6 and the data is stored in the storage device 14 within all the time. On the other hand, the operation record may be recorded by selecting only a specific time period, for example, a time period excluding nighttime when there are few users. Thereby, the recording capacity of the storage device 14 can be reduced.

  Further, in the first to fourth embodiments described above, only when a certain abnormality is detected in the elevator and the alarm is generated, the operation reproducing device 6 is automatically automatically operated only during a predetermined time period before and after that. The operation record may be recorded at. In this case, there is an advantage that it is possible to save the trouble of searching for a record at the time of occurrence of the corresponding trouble by manual operation.

  Furthermore, when an abnormality is detected, an operation record of only the location where the abnormality has occurred may be selectively recorded automatically by the operation reproduction device 6. In this case, there is an advantage that not only the recording capacity is reduced, but only the device on which the defect is multiplied can be focused on.

  The elevator operation reproduction system according to the present invention has been described with reference to the preferred embodiments. However, these embodiments have been given by way of example and are not intended to limit the scope of the invention.
