[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator remote monitoring apparatus, and more particularly to generation of alarm information in response to the cause of an open state when an elevator car door is open for a predetermined time. The present invention relates to an elevator remote monitoring device that appropriately delays

[0002]

2. Description of the Related Art Conventionally, an elevator remote monitoring device that supplies alarm information to a monitoring center or generates an alarm when a door of an elevator car does not close in a normal manner is disclosed in JP-B-63-20749. As disclosed in the above publication, the detection of the fact that the door of the elevator car has repeatedly opened and closed a predetermined number of times or more is performed, and when the detection is performed, the alert information is sent to the monitoring center assuming that the car door has failed. As described in Japanese Unexamined Patent Publication No. 1-285880, the abnormal operation of the door of the elevator car is detected by the number of times of reversing the door due to overloading of the door, and the detection is performed. In some cases, the car door is determined to be faulty and alarm information is supplied to the monitoring center. As disclosed in No. 4, the number of reversing operations of the door that occurs when the operation of closing the door of the elevator car is disturbed is measured, and when the number of times exceeds a predetermined value, the operation of closing the door is stopped. There has been known a device in which a manager's room is notified by means such as an alarm buzzer.

[0003]

In the conventional elevator remote monitoring apparatus, not only when the operation of the door of the elevator car is abnormal, but also when the door of the elevator user is improperly handled. For example, when the door safety switch is artificially operated, when the door is closed, the opening and closing of the door is reversed many times by holding down the door by hand, or when the door safety switch is closed. Even in the case where the alarm is continued to be suppressed, since the alarm information is configured to be supplied to the monitoring center, when the alarm information that the door of the elevator car is abnormally operated is notified in the monitoring center, Is it due to the inherent malfunction of the door or due to improper handling of the door by elevator users It has a problem that it is impossible to determine.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem. The purpose of the present invention is to determine whether an abnormal operation of a door of an elevator car is caused by an inherent operation error of the door. It is an object of the present invention to provide an elevator remote monitoring device that determines whether the information is artificial and reduces unnecessary alarm information to a monitoring center.

[0005]

In order to achieve the above object, the present invention controls the overall operation of the elevator car and detects that the door of the elevator car has been opened for a predetermined time or more. In an elevator remote monitoring device that includes an elevator control unit that generates alarm information and a communication device that notifies the alarm information to a monitoring center via a telephone line, the elevator control unit determines whether an elevator car door has been closed for a predetermined time. Opening / closing the cause of the door opening
Determine the failure of the device and the human ones and, by this determination
If it is determined that the cause is the failure, after a certain time
The alarm information is generated, and the cause is determined by the discrimination.
If it is determined to be
Inhibition of door closing by the user's body according to the number of times the queue is operated
State and whether the door is closed by baggage
Longer than the specified time if the door is inhibited by the body
After the elapse of a predetermined time, the alarm information is generated, and
If the door is closed, it is better than the user's body
A first means configured to generate the alarm information after a lapse of a longer time .

Further, in order to achieve the above object, the present invention controls the overall operation of the elevator car and detects alarm information by detecting that the door of the elevator car has been opened for a predetermined time or more. In an elevator remote monitoring device including an elevator control unit to be generated and a communication device that reports the alarm information to a monitoring center via a telephone line, the elevator control unit has a door of an elevator car opened for a predetermined time or more. The cause is determined to be a malfunction of the door opening / closing device or an artificial cause, and when the cause is determined to be the malfunction by the determination, the alarm information is generated after a predetermined time, and the cause is determined by the determination. If it is determined that the warning information is generated, an alarm is generated in the elevator car before the alarm information is generated, and then a time longer than the predetermined time elapses. A second means that is configured to generate the calling report information.

[0007]

According to the first means, the cause of the door of the elevator car being opened for a certain period of time is as follows. In the event of an intrinsic failure of the door opening / closing device,. If the safety is suppressed by the user's hand, etc. A determination is made as to which of the cases where the movement of the safety tissue is suppressed by luggage or the like, and as a result of the determination, the cause is. When it is determined that the alarm is issued, alarm information is generated at a normal timing. When it is determined that the above is the case, alarm information is generated at a timing later than the above timing, and the cause is. When it is determined that the alarm timing is lower, the alarm information is generated at a timing further later than the later timing. Thus, when the operation of closing the door of the elevator car is artificially obstructed, the first means delays the generation timing of the alarm information for notifying the abnormal operation of the door as compared with a normal operation. Therefore, it is possible to reduce the supply of unnecessary alarm information to the monitoring center, thereby minimizing the number of dispatches of maintenance personnel.

[0008] In the second means, the reason why the door of the elevator car is open for a predetermined time or more is as follows. In the event of an intrinsic failure of the door opening / closing device,. It is determined which of the cases where the safety is artificially suppressed, and as a result of the determination, the cause is. When it is determined that the alarm is issued, alarm information is generated at a normal timing. When it is determined that the warning is given, a buzzer or other alarm is generated in the elevator car to alert the elevator user who is obstructing the closing of the door, and the safety tissue is still artificially suppressed. Occasionally, alarm information is generated after a considerable time has elapsed. Thus, the second
Means such that when the operation of closing the door of the elevator car is artificially obstructed, the generation timing of the alarm information for notifying the abnormal operation of the door is delayed from a normal one, so As in the case of the first means, the supply of unnecessary alarm information to the monitoring center can be reduced, so that the number of dispatches of maintenance personnel can be minimized.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an elevator remote monitoring apparatus according to the present invention.

In FIG. 1, reference numeral 1 denotes an elevator control unit;
Is a door operation abnormality detection unit, 3 is an alarm information generation unit, 4 is a communication (terminal) device, 4A is a communication (telephone) line, 5 is a monitoring center, 8 is an elevator car door, 9 is an elevator car,
Reference numeral 10 denotes a car operation abnormality detection unit, and reference numeral 12 denotes a buzzer alarm generation unit. Reference numeral 6 denotes a time extending unit for delaying the generation timing of the alarm information generated by the alarm information generating unit 3 under the control of the elevator control unit 1, and 7 denotes the alarm information generating unit 3 and the buzzer alarm generating unit by the elevator control unit 1. Reference numeral 11 denotes a time setting unit for setting the operation start timing, and reference numeral 11 denotes a buzzer generation time extension unit that controls the operation start timing of the buzzer alarm generation unit 12 to be later than the set timing under the control of the elevator control unit 1.

The elevator control unit 1 performs control for operating the elevator car 9 and the door 8 of the elevator car as a whole. The car abnormality detection unit 10 detects that the operation of the elevator car 9 has an abnormality, and the door abnormality detection unit 2 detects that the operation of the door 8 of the elevator car has an abnormality. At times, a detection signal is transmitted to the elevator control unit 1. Elevator control unit 1
Receives the detection signal, drives the alert information generating unit 3 to generate alert information, and the communication (terminal) device 4 transmits the alert information to the monitoring center 5 through the communication (telephone) line 4A. I do.

Here, the overall operation of this embodiment will be described with reference to the flowchart of FIG.

However, in steps S0 to S16 in the flowchart of FIG. 2, the detection signal is sent from the door operation abnormality detection unit 2 in FIG. 1 and the door 8 is not closed as a type of the detection signal. 3 shows a processing procedure or a control procedure of information performed in the elevator control unit 1 when the detection signal indicating the operation abnormality of the above is supplied to the elevator control unit 1.

First, in step S0, it is determined whether or not the detection signal has been obtained from the door operation abnormality detection unit 2. When the detection signal has been obtained, the process proceeds to the next step S1, and any other operation is performed. If no detection signal is obtained, this flow is terminated. In step S1, when a detection signal indicating an operation abnormality indicating that the door 8 does not close is obtained as the detection signal, the process proceeds to the next step S2, and when a signal of any other type is obtained. This flow ends. Next, in step S2, it is determined whether or not a failure of the door 8, for example, a failure has occurred in the opening / closing device, and if the failure has not occurred, the process proceeds to the next step S3, where the failure has occurred. If so, the process proceeds to step S16, in which case the alarm information generating unit 3 is driven after the time set by the time setting unit 7 has elapsed, and the alarm information generating unit 3 generates alarm information. .
As described above, the alarm information is transmitted to the monitoring center 5 through the communication (terminal) device 4 and the communication (telephone) line 4A.

Subsequently, in step S3, the door 8
It is determined whether or not one or more small open / close states of the door 8 have occurred during the period in which the closing of the door has been prevented, that is, whether or not the safety switch has been operated at least once during the period. If the switch has been operated one or more times, it is determined that the user is holding down the safety hand by hand, and the process proceeds to the next step S4. It is determined that the shoe is being held down by luggage or the like, and the process proceeds to step S10. By the way, in the case where the safety tissue is held by hand, the reason for the determination in step S3 is that the power of the holding hand is temporarily weakened by holding for a relatively long time, and The above is based on the recognition that the door performs small opening and closing, and conversely, if the safety tissue is suppressed by luggage, etc., the small opening and closing of the door is not performed at all because the holding force is constant. It is based on the recognition of

In the next step S4, it is determined whether or not there is a hall call of the elevator car 9, and if there is a hall call, the process proceeds to step S6, and if there is no hall call, the process proceeds to step S5. In the step S5, the extension of the operation start time of the buzzer alarm generation section 12 is set by controlling the buzzer generation time extension section 11, and then the process proceeds to step S6. Subsequently, step S6
In, an alarm such as a buzzer is generated in the elevator car 9 to notify the elevator user that the closing operation of the door 8 is obstructed, and the process proceeds to the next step S7.
In this case, the basis of the determination in step S4 is that the hall call button should be operated inevitably when there is a user of the elevator on another floor. Since the car 9 needs to be moved, an alarm such as a buzzer is generated in the elevator car 9 at a relatively fast timing. However, when there is no hall call, it can be determined that there is no user of the elevator. Therefore, it is based on the recognition that there is no problem even if the generation of an alarm such as a buzzer in the elevator car 9 is slightly delayed. It is.

In the following step S7, the first time is set by controlling the time extending section 6, and the process proceeds to the next step S8. Subsequently, in step S8, it is determined whether the door 8 has already been closed. In this determination, if the door 8 has already been closed, the cause of hindering the closing of the door 8 has disappeared, so this flow is terminated, and when the closing of the door 8 is still hindered, Move to the next step S9. In step S9, it is determined whether or not the generation period of the detection signal has exceeded the first time set in step S7. In this determination, if the occurrence period has not yet exceeded the first time, the process returns to step S8,
In step S8, it is determined whether or not the door 8 has been closed again. If the occurrence period has already exceeded the first time, the process proceeds to the next step S16.
In the last step S16, the alarm information generation unit 3 is controlled to generate alarm information therefrom and notify the monitoring center 5. Here, the matter that is the basis of the determination in step S9 is that even if an alarm such as a buzzer is generated in the car 9, if the closing of the door 8 is still prevented, other elevator use It is unavoidable to report alarm information to the monitoring center 5 because it is considered to cause a great deal of inconvenience to persons.
Furthermore, in addition to the above-mentioned artificial cause, it is also conceivable that a failure has occurred in the safety switch, so that it is preferable to notify the monitoring center 5 of the alarm information at this time.

If it is determined in step S3 that the safety switch does not operate more than once, the process proceeds to step S10. In this case, step S10, subsequent step S11, and subsequent step S12 correspond to step S4 and step S12, respectively.
5. Since the processing is the same as step S6, the description of steps S10 to S12 is omitted. Subsequent step S
In step 13, the control unit controls the time extension unit 6 to set a second time longer than the first time set in step S7, and proceeds to the next step S14. In this case, the reason for setting the second time longer than the first time in the step S13 is that the step S10
When shifting to the processing of S12 to S12, it is considered that the safety tissue is almost suppressed for transporting the luggage or the like, so by setting the time longer than the first time, the transportation of the luggage or the like is performed. This is to prevent trouble.

Subsequently, in step S14, it is determined whether or not the door 8 has already been closed, as in step S8. In this determination, if the door 8 has already been closed, the cause of preventing the closing has disappeared, and this flow is terminated. If the closing of the door 8 is still hindered, the process proceeds to the next step S15.
In this step S15, it is determined whether or not the generation period of the detection signal has exceeded the second time set in the step S13. In this determination, if the occurrence period has not yet exceeded the second time, the process returns to step S14, and in step S14, it is determined whether the door 8 has been closed again. If the second time has already passed, the process proceeds to the last step S16. In this step S16,
As described above, the alarm information generation unit 3 is controlled, and alarm information is generated from the alarm information generation unit 3 to notify the monitoring center 5.

As described above, in this embodiment, when the operation of closing the door 8 of the elevator car 9 is artificially obstructed, the generation timing of the alarm information for notifying the abnormal operation of the door 8 is normally set. Therefore, unnecessary supply of alarm information to the monitoring center 5 can be reduced, so that the number of dispatches of maintenance personnel can be minimized. Further, prior to the generation of the alarm information, a warning is generated by a buzzer or the like in the elevator car 9 to alert an elevator user obstructing the closing of the door 8, so that the obstructor is obstructed. It has a great effect to immediately stop the sabotage being carried out.

[0022]

According to the present invention, an artificial car, such as the case where the safety of the elevator car door is suppressed by the user's hand or the case where the movement of the safety car is suppressed by luggage or the like, is suppressed. When it is determined that the door closing operation is obstructed, the generation timing of the alarm information for notifying the abnormal operation of the door is delayed, so that unnecessary alarm information to the monitoring center is not transmitted. It is possible to reduce the number of dispatches of the maintenance staff, thereby providing the effect of minimizing the number of dispatches of the maintenance staff.

Prior to the generation of the alarm information, when the elevator car door is artificially opened for a certain period of time or longer, an alarm such as a buzzer is generated in the car, and the door is closed. Since the attention is given to the elevator user obstructing the operation, there is an effect that the operation can be effectively utilized particularly when the door closing operation is obstructed by mischief or the like.
