Means that can output to the control unit 5 provided in the apparatus 2 are included.

  FIG. 3 is a diagram for explaining the operation of an embodiment of a handrail cleaning device for a passenger conveyor and an embodiment of a remote monitoring device for a handrail cleaning device according to the present invention. Hereinafter, based on this FIG. 3, it demonstrates based on operation | movement of this embodiment containing the handrail cleaning apparatus 2 mentioned above and the remote monitoring apparatus of the handrail cleaning apparatus 2. FIG.

  First, for example, a control command for starting cleaning of the handrail 1 from the monitoring center 19 is sent to the control unit 5 of the handrail cleaning device 2 via the public wireless communication network 18, the public wireless base station 17, the antenna 7, and the notification terminal device 6. In response to the cleaning start control command, the control unit 5 determines whether the passenger conveyor is currently in operation by a signal input from the passenger conveyor control device 8, as shown in step S20 of FIG. Judge whether. If this determination is yes, the handrail 1 is not cleaned here. If no, the process proceeds to step S21, and it is determined whether each device provided in the handrail cleaning device 2 and the power supply of the control unit 5 are operating normally.

  If the determination in step S21 is no, an abnormality has occurred, and an information signal indicating an abnormality is output from the control unit 5 to the notification terminal device 6. The information signal indicating the abnormality is the antenna 7, public radio The data is transmitted to the monitoring center 19 via the base station 17 and the public wireless communication network 18. As a result, a command is issued from the monitoring center 19 and an operator is dispatched to the installation location of the handrail cleaning device 2 for adjustment or maintenance of the handrail cleaning device 2. As shown in step S <b> 28, the worker performs an operation for eliminating the abnormality of the corresponding handrail cleaning device 2.

  If the determination in step S21 is yes, the process proceeds to step S22, and the cleaning unit 14 is wound up and updated under the control of the winding motor 13 by the control unit 5. Before the start of cleaning, the pedestal 9 is separated from the handrail 1, and the cleaning tool 14 is separated from the handrail 1 along with this.

  In step S22, the control unit 5 controls the winding motor 13 to perform a process of winding and updating the cleaning tool 14 by a predetermined length.

  Next, it moves to procedure S23 and the process which raises the base 9 by control of the base elevator 11 by control of the control part 5 is made. Thereby, the part of the cleaning tool 14 mounted on the base 9 is brought into contact with the surface of the handrail 1.

  Next, the process proceeds to step S24, and a signal from the control unit 5 is output to the passenger conveyor control device 8, and the passenger conveyor is operated for a predetermined operation time by the control of the passenger conveyor control device 8, and the handrail 1 is circulated and moved. Then, the surface of the handrail 1 is cleaned by the portion of the cleaning tool 14 that is in contact with the surface of the handrail 1. Note that after a predetermined operation time has elapsed, the operation of the passenger conveyor is stopped, and a signal indicating that the passenger conveyor has stopped is output from the passenger conveyor control device 8 to the control unit 5.

  After the process of step S24 described above, the process proceeds to step S25, and whether or not the cleaning tool 14 has been wound up a certain length corresponding to its entire length is stored in advance in the storage unit of the control unit 5. Judgment is made based on the length of the cleaning tool 14. If this determination is yes, a signal for stopping the operation of the passenger conveyor is output from the control unit 5 to the passenger conveyor control device 8. In response to this, the passenger conveyor control device 8 stops the operation of the passenger conveyor, and thus a signal indicating that the operation of the passenger conveyor is stopped is output to the control unit 5. Further, the control unit 5 controls the pedestal elevator 11 to lower the pedestal 9 and performs a process of separating the cleaning tool 14 from the handrail 1. Then, the process proceeds to step S26, and a signal indicating that the cleaning tool 14 needs to be replaced is output from the control unit 5 to the reporting terminal device 6, and the process proceeds to step S29. If the determination in step S25 is no, the process proceeds to step S29.

  In the above-described procedure S26, a signal indicating that the cleaning tool 14 output from the control unit 5 needs to be replaced is sent from the notification terminal device 6 via the antenna 7, the public radio base station 17, and the public radio communication network 18 to the monitoring center 19. Sent to. Thereby, a command is issued from the monitoring center 19 and an operator is dispatched to replace the cleaning tool 14 of the corresponding handrail cleaning device 2. The operator performs an operation of replacing the cleaning tool 14 of the corresponding handrail cleaning device 2 with a new cleaning tool 14.

  Further, in the above-described step S29, whether or not the wetness of the detection data measured by the wetness sensor 16 is equal to or lower than the wetness of the first basic data stored in the storage unit of the control unit 5, that is, the handrail 1 It is determined whether the surface of the portion of the cleaning tool 14 in the vicinity of the portion of the cleaning tool 14 that is in contact with is too dry. If this determination is YES, the cleaning tool 14 is too dry and the cleaning liquid is insufficient, and the procedure goes to step S30 to lower the pedestal 9 under the control of the pedestal elevator 11 by the control unit 5, The part of the cleaning tool 14 that has been in contact with the rail 1 is separated from the handrail 1. After the base 9 is lowered, the process returns to the above-described procedure S22, and the cleaning tool 14 is wound and updated. That is, each process for cleaning the handrail 1 is continued.

  Further, when it is determined in step S29 described above that the wetness of the detection data measured by the wet sensor 16 is not less than or equal to the wetness of the first basic data stored in the storage unit of the control unit 5. That is, when it is determined that the surface of the cleaning tool 14 is not too dry and the amount of cleaning liquid suitable for cleaning is maintained in an impregnated state, the process proceeds to step S31.

  Although not shown in the flowchart shown in FIG. 3, for example, after step S29, a procedure for determining whether or not the cleaning liquid is excessively impregnated in the cleaning tool 14 may be provided. In this case, after the other order S29, whether or not the wetness of the detection data measured by the wet sensor 16 is equal to or higher than the wetness of the second basic data stored in the storage unit of the control unit 5, That is, it is determined whether or not the cleaning liquid is excessively impregnated in the portion of the cleaning tool 14 that is in contact with the handrail 1. If this determination is yes, for example, a signal for stopping the operation of the passenger conveyor is output from the control unit 5 to the passenger conveyor control device 8. The passenger conveyor control device 8 performs control to stop the operation of the passenger conveyor and outputs a signal to the control unit 5 that the passenger conveyor has stopped. Further, the control unit 5 controls the pedestal elevator 11 to lower the pedestal 9 and performs a process of separating the cleaning tool 14 from the handrail 1. Further, a signal indicating that the cleaning liquid is abnormally impregnated in the cleaning tool 14 is output from the control unit 5 to the notification terminal device 6. This signal is transmitted from the reporting terminal device 6 to the monitoring center 19 via the antenna 7, public radio base station 17, and public radio communication network 18. As a result, a command is issued from the monitoring center 19 and an operator is dispatched to deal with an abnormal impregnation of the cleaning liquid in the corresponding handrail cleaning device 2. The operator performs an operation of adjusting the cleaning liquid impregnated by the cleaning tool 14 so that the amount becomes appropriate for cleaning the guide rail 1. If the above-described determination is no, the process proceeds to step S31.

  In step S31, the control unit 5 determines whether or not the passenger conveyor has stopped operating based on a signal input from the passenger conveyor control device 8. If the passenger conveyor is in operation and this determination is NO, the cleaning tool 14 is brought into contact with the surface of the handrail 1 for a predetermined contact time that is less than the predetermined operation time of the passenger conveyor. The handrail 1 is cleaned, and the base 9 is lowered by the control of the base lift 11 under the control of the control unit 5 after a predetermined contact time has elapsed. In this state, the process returns to step S22 to wind the cleaning tool 14 Update processing is performed.

  If the determination in step S31 is yes, the process proceeds to step S32, the cleaning of the handrail 1 is completed, that is, the pedestal 9 is lowered by the control of the pedestal elevator 11 by the control unit 5, and the cleaning tool 14 is moved to the surface of the handrail 1. The process which makes it remove | separate from and makes it a cleaning standby state is made | formed. At this time, a cleaning end signal is transmitted from the control unit 5 to the monitoring center 19 via the reporting terminal device 6, the antenna 7, the public radio base station 17, and the public radio communication network 18. Thereby, the monitoring center 19 can confirm that the cleaning of the surface of the handrail 1 has been completed.

  According to the passenger rail handrail cleaning device 2 of the present embodiment configured as described above, the surface of the cleaning tool 14 is the surface of the handrail 1 depending on the wetness of the surface of the cleaning tool 14 measured by the wetness sensor 16. It is possible to manage whether or not the wetness suitable for cleaning the surface is maintained. That is, by appropriately managing the wetness, it is always appropriate for the surface of the handrail 1 regardless of the environmental temperature, which is the temperature around the passenger conveyor, and various cleaning conditions such as the length of the passenger conveyor. A desired amount of cleaning liquid can be supplied via the cleaning tool 14 to achieve the desired cleaning of the surface of the handrail 1. That is, the cleaning accuracy can be improved and high reliability can be ensured.
