Description
Technical Field
The embodiment of the invention relates to a passenger conveyor control device, a remote monitoring center device, a maintenance personnel carrying device and a landing display device.
Background
In a passenger conveyor represented by an escalator, there is a remote monitoring system that notifies a remote monitoring center of occurrence of an abnormality when the operation of the escalator is stopped due to occurrence of the abnormality during traveling, and returns the escalator to a normal operation by a restart operation of the escalator remotely performed from the remote monitoring center.
As a conventional example of restarting an escalator when stopping, the following proposals are made: the restart is rejected in case the restart of the escalator by remote operation is inappropriate. In this case, in the case of refusing the restart, no on-site attendance instruction is made to the maintenance personnel.
In addition, the following scheme for ensuring security is proposed: if the remote stop switch and the on-site stop switch are both turned on instead of being restarted, the escalator is not restarted only by the judgment of the on-site.
Disclosure of Invention
When an escalator (passenger conveyor) stops due to a failure, the escalator may be restarted to allow the escalator to travel again. However, if the restart of the escalator is performed in the case of a permanent failure, the failure of the escalator may become serious, and if the escalator moves temporarily at the time of restart, the user of the escalator may be affected.
The invention provides a passenger conveyor control device, a remote monitoring center device, a maintenance personnel carrying device and a landing display device, wherein when the passenger conveyor has a fault, if the remote monitoring center is not suitable for restarting, the restarting is refused, unnecessary restarting is not implemented by a monitor at a remote place, and furthermore, the on-site attendance notification of maintenance personnel is implemented, so that the maintenance personnel can complete rapid on-site confirmation and recovery, thereby preventing the service reduction of the passenger conveyor.
A passenger conveyor control device according to an embodiment is connected to a remote monitoring center device that remotely monitors a passenger conveyor and controls operation of the passenger conveyor, and includes: a travel control unit that controls operation and stop of the passenger conveyor, and that, when a restart request signal is received from the remote monitoring center device, performs start of the passenger conveyor while stopped; an abnormality detection unit that detects an abnormality of the passenger conveyor and transmits an abnormality signal to the remote monitoring center device; and a restart control unit that determines whether or not a restart of the passenger conveyor in a stopped state is possible when the restart request signal for the passenger conveyor is received from the remote monitoring center device, and when the restart is possible, causes the travel control unit to restart the passenger conveyor and transmit a restart normal execution signal to the remote monitoring center device, and when the restart is not possible, transmits a restart rejection signal to the remote monitoring center device without restarting the passenger conveyor.
According to the passenger conveyor control device with the above configuration, when the passenger conveyor has a failure, if the restart from the remote monitoring center is not appropriate, the restart is rejected, unnecessary restart by a remote monitor is not performed, and further, the field attendance notification of the maintenance staff is performed, so that the maintenance staff completes rapid field confirmation and recovery, thereby preventing the service reduction of the passenger conveyor.

Detailed Description
< embodiment 1 >
Fig. 1 is a block diagram showing a configuration of an escalator (passenger conveyor) remote monitoring system 100 according to embodiment 1.
As shown in fig. 1, the escalator remote monitoring system 100 includes: an escalator (passenger conveyor) control device 1, a remote monitoring center device 5, and a serviceman carrying device 11.
The escalator control device 1 includes a travel control unit 2, an abnormality detection unit 3, and a restart control unit 4.
The travel control unit 2 controls the travel, stop, and restart processes of the escalator (passenger conveyor).
The abnormality detection unit 3 detects an abnormality of the escalator, assigns abnormality information indicating whether or not the restart of the escalator is possible, and transmits the abnormality information to the remote monitoring center device 5.
When receiving a restart request signal for the escalator from the remote monitoring center device 5, the restart control unit 4 performs the restart of the escalator by the travel control unit 2 and transmits a normal restart of the escalator to the remote monitoring center device 5 if the abnormality is an abnormality that enables the restart of the escalator based on the abnormality information that is assigned by the abnormality detection unit 3 as to whether the restart is possible. Further, if the abnormality is such that the restart of the escalator cannot be performed, the restart control unit 4 transmits a restart rejection signal to the remote monitoring center device 5 without performing the restart by the travel control unit 2.
The remote monitoring center device 5 includes: an abnormality detection display unit 6, a restart start unit 7, a restart request history unit 8, a restart request transmission unit 9, and a field attendance notification unit 10.
When the abnormality information is received from the abnormality detection unit 3 of the escalator control device 1, the abnormality detection display unit 6 displays the abnormality information.
The restart start unit 7 requests a restart operation from a remote monitor.
The restart request history unit 8 controls whether to execute or reject the restart request to the escalator based on information on whether a restart rejection signal from the escalator control device 1 has been received in the past or whether a recovery signal for the escalator has been received from the serviceman carrying device 11 when a restart rejection signal has been received in the past in response to the restart request from the restart start unit 7. In addition, when the restart rejection signal is present in the past and the recovery signal is not received from the serviceman carrying device 11, the restart request history unit 8 invalidates the operation control of the restart start unit 7 and performs the attendance notification control of the serviceman. Further, if a recovery signal is received from the serviceman carrying device 11 when the operation control of the restart initiator 7 is invalid, the restart request history unit 8 validates the operation control of the restart initiator 7.
If a restart rejection signal is received from the restart request history unit 8, the restart request transmission unit 9 directly stops the process. Further, if a restart request is received, the restart request transmitter 9 transmits a restart request to the restart controller 4, and upon receiving a restart execution completion signal or a restart rejection signal, transmits the result to the restart request history unit 8.
When there is a request for attendance from the serviceman from the restart request history unit 8, the field attendance notification unit 10 transmits an attendance request signal to the serviceman carrying device 11.
The serviceman carrying device 11 includes: an attendance display unit 12, an attendance alarm unit 13, a site restoration input unit 14, and a site restoration output unit 15.
The attendance display unit 12 receives the attendance notification signal from the on-site attendance notification unit 10 of the remote monitoring center apparatus 5, and displays the attendance notification.
The attendance alarm unit 13 receives an attendance notification signal from the attendance display unit 12 and sounds an alarm.
In the case where the escalator is recovered due to the field attendance of the serviceman, the field recovery input section 14 generates a recovery signal indicating the same.
The site restoration output unit 15 receives the restoration signal from the site restoration input unit 14, and transmits the restoration signal to the restart request history unit 8 of the remote monitoring center apparatus 5.
Next, the processing steps of the escalator remote monitoring system 100 according to embodiment 1 will be described with reference to the flowcharts of fig. 2A and 2B.
In fig. 2A and 2B, when an abnormality occurs during steady travel and the escalator suddenly stops under the control of the travel control unit 2, the abnormality detection unit 3 detects the abnormality (step S1), and stores (registers) a determination as to whether or not restart is possible (step S2). The abnormality detection unit 3 sends an abnormality signal to the abnormality detection display unit 6 of the remote monitoring center apparatus 5 (step S2).
When the remote monitoring center apparatus 5 receives the abnormality signal (yes in step S11), the abnormality detection display unit 6 displays an abnormality display screen based on the received abnormality signal. Then, the monitor of the remote monitoring center apparatus 5 requests the escalator to restart from the restart start unit 7. At this time, the restart request history section 8 confirms whether or not a restart rejection signal for the escalator to be restarted has been received in the past (step S12). If the restart rejection signal has not been received in the past (no at step S12), the restart request is transmitted from the restart request history unit 8 to the restart request transmitter 9, and the restart request is output from the restart request transmitter 9 to the restart controller 4 (step S14). Further, if the restart rejection signal is received in the past (yes in step S12), but the recovery signal is received from the field recovery output unit 15 of the serviceman carry unit 11 (yes in step S13), the restart request is transmitted from the restart request history unit 8 to the restart request transmitter 9, and the restart request is output from the restart request transmitter 9 to the restart controller 4 (step S14).
In the restart request judgment by the restart request history section 8 of the remote monitoring center 5, if a restart rejection signal is received in the past (yes in step S12) and a recovery signal is not received from the on-site recovery output section 15 of the serviceman carrying device 11 (no in step S13), restart of the escalator is not executed and a restart rejection (restart disabled) is registered in the restart request history section 8 (step S15).
When a restart request is made from the restart request transmitter 9 to the restart controller 4 (step S14), if the information collected by the restart controller 4 from the travel controller 2 and the abnormality detector 3 is an abnormality that can be restarted, such as continuation of the software stopped state during the stop of the escalator (yes in step S3), the restart controller 4 restarts the travel controller 2 (step S4). After the restart of the travel control unit 2 is completed, a restart normal execution signal is transmitted from the restart control unit 4 to the remote monitoring center device 5, and the escalator enters a steady travel state (yes at step S5). When the information collected by the restart control unit 4 from the travel control unit 2 and the abnormality detection unit 3 is an abnormality that cannot be restarted, such as a state in which the emergency stop switch is operating even during the stop of the escalator, or the like, the restart of the escalator is not performed and the remote monitoring center device 5 is notified of a restart rejection (no at step S3).
In the above, if the escalator is not restarted but registered as a restart rejection in the restart request history unit 8 and the restart request transmission unit 9 of the remote monitoring center apparatus 5, the restart request history unit 8 invalidates the operation of the restart start unit 7 (step S16). Further, the restart request history unit 8 transmits the attendance notification to the attendance display unit 12 of the serviceman carrying device 11 via the on-site attendance notification unit 10, and displays the attendance notification on the attendance display unit 12, and the attendance alarm unit 13 rings to notify the serviceman of the attendance (step S17).
After the maintenance worker goes out to the site, the maintenance worker performs a recovery operation such as confirmation or repair of an abnormal condition of the escalator to be monitored, and when a recovery input is made from the site recovery input unit 14, the recovery input is transmitted to the restart request history unit 8 of the remote monitoring center 5 via the site recovery output unit 15. The restart request history unit 8 executes the recovery process to validate the operation of the restart start unit 7 (step S18). When the escalator control device 1 is started, the escalator enters a steady traveling state (yes in step S5). In a state where the recovery operation such as confirmation of an abnormal condition of the escalator or repair is not performed (no in step S5), the operation of the restart starting unit 7 is kept invalid, and the field attendance notification by the maintenance worker is continued.
As a restoration input method of the serviceman carrier 11, a process of pressing a restoration button on the screen of the serviceman carrier 11, a manual input of a restoration job, or the like can notify of restoration. The input method for recovery is an example, and other recovery methods may be used.
As described above, according to embodiment 1, when restarting the escalator remotely at the time of abnormal stop of the escalator, control is performed such that the restart is executed only in an appropriate case. Therefore, when the escalator is not normally operated even if the escalator is restarted by remote monitoring, it is possible to prevent the remote monitor from performing an unnecessary restart operation. In addition, when restarting is not appropriate, a field attendance for an escalator abnormality is notified to a maintenance person, and the maintenance person can give priority to the escalator as soon as possible, perform field confirmation and field restoration, and can prevent a service degradation of the escalator.
< embodiment 2 >
Fig. 3 is a block diagram showing a configuration of an escalator (passenger conveyor) remote monitoring system 200 according to embodiment 2.
The escalator remote monitoring system 200 according to embodiment 2 is configured by adding the attendance list display unit 16 as the remote monitoring center device 50 to the configuration of embodiment 1.
The attendance list display unit 16 tabulates and displays attendance items notified of the attendance from the attendance notification unit 10 to the serviceman carrying device 11 via the remote monitoring center device 50.
The restart request history unit 8 according to embodiment 2 is configured to add the following functions to the configuration of embodiment 1: when the escalator is recovered and receives a recovery signal from the on-site recovery output section 15, the recovery signal is transmitted to the on-site attendance notification section 10. Further, the on-site attendance notification unit 10 has a function of transmitting a recovery signal to the attendance list display unit 16 when the recovery signal is received from the restart request history unit 8.
Next, the operation of the escalator remote monitoring system 200 according to embodiment 2 will be described with reference to the flowcharts of fig. 4A and 4B. In fig. 4A and 4B, the same processes as those shown in fig. 2A and 2B are denoted by the same step numbers, and the description thereof is omitted.
In the processing of step 16, if the escalator is not restarted but registered as a restart rejection in the restart request history unit 8 and the restart request transmission unit 9 of the remote monitoring center apparatus 50, the restart request history unit 8 invalidates the operation of the restart start unit 7. When the on-site attendance of the maintenance worker is notified from the restart request history unit 8 of the remote monitoring center apparatus 50 to the on-site attendance notification unit 10, the on-site attendance is recognized as a required item, information is transmitted from the on-site attendance notification unit 10 to the attendance item list display unit 16, and the attendance item is displayed on the attendance item list display unit 16 (step S21). Then, the restart request history unit 8 transmits an attendance notification to the attendance display unit 12 of the serviceman carrying device 11 via the on-site attendance notification unit 10, and displays the attendance. In addition, the attendance is notified by the ringing from the attendance alarm portion 13 (step S17).
When the maintenance person has recovered the escalator of the object at the site and completed the recovery input, a recovery signal is transmitted from the restart request history unit 8 to the attendance list display unit 16 via the site attendance notification unit 10. When the resume signal is received, the resume item is deleted from the attendance item list display section 16 (step S22).
When the escalator recovery notification is received from the serviceman carrying device 11 (yes in step S23), a restart request can be output from the restart request history unit 8 of the remote monitoring center device 50 to the restart controller 4 of the escalator control device 1 (step S24).
According to embodiment 2, when restarting is not appropriate, the remote monitoring center apparatus 50 manages an early field attendance and a recovery request of a maintenance worker, and thus it is possible to prevent a service drop due to an omission of the recovery operation of the escalator.
< embodiment 3 >
Fig. 5 is a block diagram showing a configuration of an escalator (passenger conveyor) remote monitoring system 300 according to embodiment 3.
The escalator remote monitoring system 300 according to embodiment 3 is configured to add the following components to the configuration of embodiment 2: a landing display device provided in an escalator landing 17 and connected to the escalator control device 1, a field traveling state display section 18 provided in the landing display device, an abnormal information maintenance notification section 20 provided in the remote monitoring center device 51, a restart execution result notification section 19 provided in the serviceman carrying device 110, and an abnormal information display section 21.
The on-site travel state display unit 18 acquires the information on whether the escalator is traveling or stopped from the travel control unit 2, acquires the abnormality information from the abnormality detection unit 3, and displays the information on each.
When the restart rejection signal is detected by the restart request transmission unit 9 when the restart is rejected from the restart control unit 4 or the restart request history unit 8, the abnormality information maintenance notification unit 20 of the remote monitoring center apparatus 51 acquires the abnormality detection information of the abnormality detection display unit 6 and transmits the abnormality detection information to the serviceman carrying apparatus 11.
The restart execution result notification unit 19 of the serviceman's portable device 11 receives, from the restart request transmission unit 9, either a restart execution signal when the restart is executed from the restart control unit 4 or a restart rejection signal when the restart is rejected from the restart control unit 4 or the restart request history unit 8. The abnormal information display unit 21 displays the escalator abnormal information transmitted from the abnormal information maintenance notifying unit 20 of the remote monitoring center 51.
Next, the processing steps of the escalator remote monitoring system 300 according to embodiment 3 will be described with reference to the flowcharts of fig. 6A and 6B. In fig. 6A and 6B, the same processes as those shown in fig. 4A and 4B are assigned the same step numbers, and the description thereof is omitted.
When the escalator is stopped based on the information of the travel control section 2 or when an abnormality occurs in the escalator based on the information of the abnormality detection section 3, the information is displayed on the on-site traveling state display section 18 of the escalator landing 17 (step S6).
When the restart is performed by the restart controller 4, the restart execution result notification unit 19 of the serviceman carry device 110 receives and displays a restart execution signal from the restart request transmitter 9 of the remote monitoring center 51. This notifies the maintenance worker of the restart operation, and the escalator enters a stable traveling state. Then, the on-site running state display section 18 of the escalator landing 17 displays the fact that the vehicle is running stably (step S7).
On the other hand, when the restart control unit 4 notifies the restart request history unit 8 of the restart rejection (yes in step S12), the restart execution result notification unit 19 receives a restart rejection signal from the restart request transmission unit 9, and notifies the restart rejection to a maintenance person. Then, the abnormal information maintenance notifying unit 20 detects a restart rejection signal from the restart request transmitting unit 9 and receives the escalator abnormal information from the abnormality detection display unit 6. Then, the abnormality information of the escalator is notified to and displayed on the abnormality information display unit 21 of the serviceman carrying device 11 (step S31).
As described above, according to embodiment 3, when the escalator is stable or abnormal, the on-site traveling state is displayed in the escalator landing 17, and thus it is possible to notify maintenance personnel or guests. Further, whether the restart of the escalator control device 1 is performed or the restart of the escalator control device 1 is rejected can be notified to the serviceman carrying device 11, and an abnormal state can be notified to the serviceman carrying device 11 when the restart is rejected. Therefore, the maintainer side can grasp the abnormal severity of the escalator to implement the recovery operation of the escalator, and can prevent the service reduction of the escalator.
In the above embodiments, the description has been given by taking the escalator as an example of the passenger conveyor, but the present invention is not limited to this, and it is needless to say that the present invention can be applied to various passenger conveyors such as a moving walkway.
Several embodiments of the present invention have been described above, but these embodiments are provided as examples and are not intended to limit the scope of the present invention. These new embodiments can be implemented in other various ways, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the scope equivalent thereto.
