Description

  The present invention relates to elevator control systems such as elevators and escalators, and more particularly to techniques for elevator control systems that are suitable for recovery from disasters such as earthquakes.

  Conventionally, as an earthquake countermeasure for elevators, when an earthquake detector detects that an earthquake has occurred, an emergency operation control signal is put in place to stop the operation by placing a running car on the nearest floor and putting it in a suspended state. Is continuously reported to the monitoring center via the communication line until normal operation is started, and the monitoring center that receives the notification of the operation stop signal dispatches a specialist engineer to perform recovery work based on the operation stop signal. It was.

However, when an earthquake of a predetermined magnitude or more occurs, a large number of elevators are in a dormant state in a wide range, so a number of the dormant signals are sent from the wide range to the monitoring center at the same time. In order to avoid the problem that reporting becomes impossible or delays the restoration of the elevator due to a significant delay, a timer is started with the output of the operation stop signal, and the operation stop even after the timer set time has elapsed. Elevators whose signals are in the output state have been notified of the fact that they have not been restored to the monitoring center, and technology has been known to promptly restore the elevators that are in a suspended state and prevent a drop in elevator service. (See Patent Document 1).

  In the prior art, after the earthquake detector detects the earthquake, the predetermined period until the notification that the earthquake has not been restored, which is set in order to avoid the influence of the disruption of the general communication line due to the earthquake, is set to the scale of the earthquake. Regardless, the period until the disruption of the communication line converges is not a little affected by the magnitude of the earthquake. The problem is that the recovery response will be delayed due to waiting until the end of the period, and further, since the notification after the predetermined period has not yet been recovered, the operating state of the elevator, for example, the confinement accident state, power failure accident state, seismic control operation Since the operation state such as the completion state cannot be grasped, there is a problem that the recovery cannot be promptly performed.

  The present invention has been made in order to solve the above-described problem, and monitoring of an elevator capable of efficiently grasping information (hereinafter referred to as “operating state information”) related to the operating state of the elevator in the earthquake-affected area immediately after the occurrence of the earthquake. Providing a control system.

Based on the seismic detection of the seismic detector installed in the building with the elevator, the elevator control device that switches the elevator operation from normal operation to earthquake control operation and operates the elevator, and monitors the operating state of the elevator In the elevator monitoring system comprising a monitoring terminal for storing the operation state information and reporting to the monitoring center device for remotely monitoring the elevator,
A timer that can be activated in response to the earthquake detection and that can change the set time according to the level of the level of the earthquake detection signal is provided, and at the end of the set time of the timer, the operation state information stored in the monitoring terminal The operating state information of the elevator that has not been read out is reported from the monitoring terminal to the monitoring center device.

After the earthquake occurs, by changing the read-out period of the operating state of the elevator that the monitoring center device reads out, which is set to avoid the influence of general communication line disruption due to the earthquake, according to the magnitude of the earthquake, Since the operating state of the elevator can be grasped efficiently, there is an effect that it is possible to quickly cope with the restoration work of the elevator.
In addition, since the monitoring center device immediately reads out the operating state information due to the occurrence of an earthquake, the operating state of the elevator can be grasped at an early stage, and the operating state information is kept within a predetermined period due to general communication line confusion. As for the operating status information of elevators that could not be read out, the operating status information is reported to the monitoring center device at the end of the predetermined period, so that the operating status of the elevator that was damaged by the earthquake can be read from the monitoring center device Even in the absence, since the operating state of the elevator can be grasped, there is an effect that it is possible to quickly deal with the restoration work of the elevator.

Information such as a confinement accident and a power failure detected by the confinement detection unit 31a and the power failure detection unit 31c of the monitoring terminal device 3 is stored in the storage unit 32 as operation state information and is also output to the elevator control device 2 to Elevator operation control corresponding to the accident is performed.
Further, the operation state information such as the confinement accident and the power outage accident is notified to the monitoring center device 4 through the general communication line 6, and appropriate recovery measures are taken based on the notification.

Next, an example of the notification process of the driving | running state information according to an earthquake occurrence is demonstrated using the flowchart of FIG.
When the earthquake detector 1 detects an earthquake (step S1) and outputs an earthquake detection signal to the elevator control device 2, in the elevator control device 2 to which the earthquake detection signal is input, the control unit 21 operates the earthquake control of the elevator. The earthquake detection information is output to the monitoring center 4, and one of the timer activation signals set in accordance with the level of the detection signal, that is, the magnitude of the earthquake, is sent to the monitoring terminal device 3. Output (step S2).
Then, in the monitoring terminal device 3 that has received the timer driving signal, the low timer value or the high timer stored in the storage unit 32 based on the timer starting signal corresponding to the detection signal level received by the control unit 31. A value is selected and set in the timer 31a as a predetermined time (step S3a, step S3b).

Further, the control unit 31 monitors whether or not an abnormality such as a confinement accident has occurred in the elevator (step S4), and when an abnormality has occurred, the operation of the timer 31a is stopped (step S5) and monitored. The center 4 is notified of an abnormality in which a confinement accident has occurred (step S6), and the process ends.
If no abnormality has occurred in the elevator in step S4, it is determined whether or not the seismic control operation is completed, that is, whether or not the elevator is in a dormant state (step S7). Returning to step S4, the occurrence of abnormality in the elevator is monitored until the completion of the seismic control operation.
On the other hand, when it is determined in step S7 that the earthquake control operation has been completed, whether or not an abnormality such as a power outage accident has occurred is further monitored (step S8), and the monitoring result that a power outage accident has occurred is monitored. In this case, the timer 31a is stopped (step S9), a power failure notification is sent to the monitoring center 4 (step S10), and the operating state information is reported to the monitoring center 4 within the backup period of the auxiliary power supply (step S14).

  When the monitoring result indicates that a power failure has not occurred in step S8, the monitoring center device 4 that has received the earthquake detection signal reads the operation state information stored in the storage unit 32 of the monitoring terminal 3. Whether or not the reading is completed is determined by referring to the status reading unit 42c5 of the monitoring information 42c by checking whether the reading is completed or not (step S11). When the determination is made, the timer 31a is stopped (step S12) and the process ends.

On the other hand, in the step S11, when there is incomplete in the state reading unit 42c5 and the reading is not completed, it is determined whether or not a predetermined time set in the timer 31a has passed (step S13).
If it is determined in step S13 that the predetermined time has not elapsed, the process returns to step S8, and steps S8 and S11 are repeated until the predetermined time in step S13 has elapsed.
On the other hand, when the predetermined time set in the timer 31a elapses in the determination of the step 13, the monitoring center device is transmitted despite the operation state information transmission command signal and the operation state information transmitted from the monitoring center device 4. The elevator in which the information reception confirmation signal or the like from 4 has not been received reports its own operating state information to the monitoring center device 4 (step S14) and ends.

  Note that the auxiliary power supply has a backup capacity that can control various operations until after the earthquake control operation is completed even if a power failure occurs together with the occurrence of an earthquake.

  According to the above embodiment, even when a wide-area disaster such as an earthquake occurs, even when the operating state information of the elevator cannot be read from the monitoring center device, the elevator operating state in the affected area can be quickly grasped and a dispatch instruction is issued. There is an effect that can.
