If an abnormality occurs on the escalator and the vehicle is stopped until the maintenance staff goes to the site to perform restoration work as described above, the user will not be able to use the escalator at all during that time, which is convenient. There was a problem that it dropped significantly.

A technology has also been proposed in which maintenance personnel manually restart the escalator when it stops, but even with this technology, it still takes time for the escalator to resume running, and the escalator is stopped during that time. There was a problem that was continued.

The present invention has been made in view of the above circumstances, and even when an abnormality is detected on the passenger conveyor, the passenger conveyor and the passenger conveyor are designed so as not to stop the traveling as much as possible and not to reduce the convenience of the user. It is an object of the present invention to provide a remote monitoring center device, a remote monitoring system for a passenger conveyor, and a passenger conveyor control method.

According to the embodiment for achieving the above object, the passenger conveyor for traveling for transporting the user includes an abnormality detection device and a passenger conveyor control device. The abnormality detection device detects an abnormality in the passenger conveyor. The passenger conveyor control device stops running when an abnormality is detected by the abnormality detection device while traveling in a predetermined direction, and determines whether or not the abnormality is due to a failure that cannot travel. When it is determined that the cause is not due to a failure that cannot be traveled, it is determined whether or not it is possible to travel in the direction opposite to the direction in which the vehicle was traveling by performing a predetermined automatic diagnostic operation, and the vehicle travels in the opposite direction. If it is determined that possible, to run in the running to have a direction opposite to the direction, when it is determined to be due to the running impossible failure, Ru was continued stopped.

The operation control unit 106a controls the operation of the drive device 104 to drive the step 103, and when an abnormality is detected by the drive device abnormality detection unit 107, the operation equipment abnormality detection unit 108, or the communication equipment abnormality detection unit 109, Stop driving. Further, when the driving is stopped, the driving control unit 106a is an automatic diagnostic driving execution determination unit 106c, which will be described later, for determining whether or not the driving can be performed in the direction opposite to the direction in which the vehicle has been traveling. If it is determined that is feasible, the automatic diagnostic operation is executed. The details of the automatic diagnosis operation will be described later. The operation information reporting unit 106b uses the operation control unit 106a to provide information on the operation of the escalator 10, such as stopping the traveling of the step 103, starting the execution of the automatic diagnosis operation, starting the traveling in the reverse direction, or resuming the traveling in the forward direction. It is transmitted to the remote monitoring center device 20. When the escalator 10 is stopped, the automatic diagnosis operation execution determination unit 106c determines whether or not the automatic diagnosis operation can be executed based on a command from the remote monitoring center device 20 described later.

<Operation of remote monitoring system for escalator according to the first embodiment>
Next, the operation of the remote monitoring system 1A of the escalator according to the present embodiment will be described with reference to the sequence diagram of FIG. First, when the escalator 10 is normally traveling in the forward direction, for example, upward (S1), an abnormality occurs in either the drive device abnormality detection unit 107, the driving equipment abnormality detection unit 108, or the communication equipment abnormality detection unit 109. When it is detected, the escalator 10 is stopped by the operation control unit 106a of the escalator control device 106A (S2).

When the operation of the escalator 10 is stopped, the stop information is issued by the operation information issuing unit 106b and transmitted to the remote monitoring center device 20 (S3). In the remote monitoring center device 20, the stop information transmitted from the escalator control device 106A is received by the operation information receiving unit 21.

When the operation information receiving unit 21 receives the stop information of the escalator 10, the maintenance staff issuing unit 22 transmits the stop information to the maintenance staff terminal 30 (S4). At the maintenance staff terminal 30, the stop information of the escalator 10 transmitted from the remote monitoring center device 20 is output as text information, voice information, or the like, and is notified to the maintenance staff (S5). When the operation information receiving unit 21 receives the stop information of the escalator 10, the automatic diagnosis operation execution command unit 23 generates an automatic diagnosis operation execution command and transmits it to the escalator control device 106A (S6).

In the escalator control device 106A, the automatic diagnosis operation execution command transmitted from the remote monitoring center device 20 is received by the automatic diagnosis operation execution determination unit 106c, and the operation control unit 106a is directed in the direction opposite to the direction in which the vehicle was traveling. It is inquired whether or not the automatic diagnostic operation for determining whether or not the vehicle can travel in a certain downward direction is feasible. In response to the inquiry, the operation control unit 106a determines whether or not there is a user on the escalator 10 based on the imaging information of the step 103 of the escalator 10 and its surroundings taken by the camera device 110 ( S7). Here, when it is determined that there is a user on board, the user waits until the user gets off the escalator 10 (“YES” in S7).

When it is detected that there are no more users on board (“NO” in S7), it is determined that the automatic diagnosis driving execution determination unit 106c has enabled the automatic diagnosis operation, and the operation control unit 106a performs the automatic diagnosis operation. It is started (S8).

In the automatic diagnosis operation, for example, when the step 103 of the escalator 10 is advanced by one step in the traveling direction up to that point and then advanced by one step, and it is confirmed that there is no abnormality in the operation in either direction, it is further increased. Run at a low speed for one lap in the direction opposite to the running direction up to. After confirming that there is no abnormality in the low-speed running, the vehicle is run in the opposite direction at a steady speed for a certain period of time (for example, 1 minute). Then, when it is confirmed that there is no abnormality in the steady-speed running, it is judged that there is no problem in running in the opposite direction. The processing of this automatic diagnosis operation is an example, and the order of processing, forward movement, the number of steps of the step to be moved backward, running speed, running time, etc. can be changed as appropriate.

When it is determined by the automatic diagnosis operation that there is no problem in traveling in the opposite direction, the operation control unit 106a confirms whether or not there is any abnormality in the step 103 and its surroundings based on the image pickup information taken by the camera device 110. Will be done. Here, if it is determined by the automatic diagnosis operation that the vehicle cannot travel in the opposite direction, or if it is determined by the imaging information that there is an abnormality in the step 103 and its surroundings, it is determined that the vehicle cannot travel in the opposite direction. (“NO” in S9), the stopped state of the escalator 10 is continued, and information on the determination result of the inability to travel in the opposite direction is transmitted to the remote monitoring center device 20 (S10).

In the remote monitoring center device 20, the information on the determination result transmitted from the escalator control device 106A is received by the operation information receiving unit 21, and is transmitted to the maintenance staff terminal 30 by the maintenance staff issuing unit 22 (S11). The maintenance staff terminal 30 outputs information on the determination result of the inability to travel in the opposite direction of the escalator 10 transmitted from the remote monitoring center device 20, and notifies the maintenance staff (S12).

In step S9, it is determined that there is no problem in traveling in the reverse direction by the automatic diagnosis operation, and further, it is determined that traveling in the reverse direction is possible because it is determined that there is no abnormality in the step 103 and its surroundings based on the imaging information. Then (“YES” in S9), the operation control unit 106a starts traveling of the escalator 10 in the opposite direction (S13).

When traveling in the reverse direction is started, the driving information issuing unit 106b issues reverse traveling information and transmits it to the remote monitoring center device 20 (S14). In the remote monitoring center device 20, the reverse travel information transmitted from the escalator control device 106A is received by the operation information receiving unit 21, and is transmitted to the maintenance staff terminal 30 by the maintenance staff reporting unit 22 (S15). At the maintenance staff terminal 30, travel start information in the opposite direction of the escalator 10 transmitted from the remote monitoring center device 20 is output and notified to the maintenance staff (S16).

After that, when the maintenance staff who confirmed the information output to the maintenance staff terminal 30 arrives at the installation site of the escalator 10, if the escalator 10 is running in the opposite direction, it is stopped by the maintenance staff's manual operation and inspected. Work is done. When the escalator 10 becomes capable of traveling normally by the inspection work (“YES” in S17), the forward traveling in the upward direction is restarted by the operation of the maintenance staff (S18). When the escalator 10 resumes traveling in the upward direction, the driving information issuing unit 106b issues forward traveling restart information and transmits it to the remote monitoring center device 20 (S19).

In the remote monitoring center device 20, the forward travel restart information transmitted from the escalator control device 106A is received by the operation information receiving unit 21, and is transmitted to the maintenance staff terminal 30 by the maintenance staff reporting unit 22 (S20). The maintenance staff terminal 30 outputs the forward travel start information of the escalator 10 transmitted from the remote monitoring center device 20 (S21).

According to the first embodiment described above, when an abnormality is detected by the escalator and the traveling is stopped, the traveling is performed in the opposite direction if possible until the maintenance personnel who perform the inspection work arrives. It is possible to prevent the convenience of the user from being reduced as much as possible.

When the execution possibility is inquired, the operation control unit 106a sends a request for determining whether or not the automatic diagnosis operation can be started to the failure state determination unit 106d. When the failure state determination unit 106d acquires a request for determining whether or not to start execution of the automatic diagnosis operation from the operation control unit 106a, the failure state determination unit 106d causes an abnormality by the drive device abnormality detection unit 107, the operation equipment abnormality detection unit 108, and the communication equipment abnormality detection unit 109. From the detection status and the abnormality detection status based on the image pickup information of the camera device 110, it is determined whether or not the generated abnormality is a permanent failure in which the escalator 10 should not be operated.

Here, if it is determined that the abnormality that has occurred is not a permanent failure (“NO” in S37), it is determined that the automatic diagnostic operation can be started, and the operation control unit 106a determines that the user is on the escalator 10. After it is detected that there is no more, the automatic diagnostic operation is started (“NO” in S38, S39). After that, the processes executed in steps S40 to S52 are the same as the processes in steps S9 to S21 described in the first embodiment, and thus detailed description thereof will be omitted.

Further, in step S37, when it is determined that the generated abnormality is a permanent failure in which the escalator 10 should not be operated (“YES” in S37), the stopped state of the escalator 10 is continued, and the determination result is obtained. It is transmitted from the operation information reporting unit 106b to the remote monitoring center device 20 (S41), transmitted to the maintenance staff terminal 30 by the maintenance staff reporting unit 22 (S42), and output by the maintenance staff terminal 30 (S43).

According to the second embodiment described above, when an abnormality is detected by the escalator and the traveling is stopped, the traveling in the reverse direction is possible only if the abnormality is not a permanent failure in which the escalator should not be operated. By executing the automatic diagnostic operation for determining whether or not there is, it is possible to efficiently and accurately perform traveling control in the reverse direction.
