Detect that. The control unit 32 outputs a command for stopping the driving of the first escalator 1 to the drive control device 40 when it is detected that a load equal to or greater than the set value is applied to the pressure-sensitive sensor cable 31.

  Further, at this time, the control unit 32 causes the remote monitoring device 50 to detect the first because an object or the like is sandwiched between the foreign matter on the deck board 13 and the moving handrail 12 and the load becomes equal to or higher than the set value. Notify that driving of the escalator 1 has been stopped. Further, at this time, the control unit 32 outputs an operation command to the notification unit 33 to notify the escalator user that the driving of the first escalator 1 has stopped. Here, as the notification unit 33, for example, a speaker, a lamp, a display, or the like can be used.

  The operation of the foreign object detection device on the passenger conveyor deck board according to the first embodiment of the present invention will be described below with reference to the flowchart of FIG. Note that the process of FIG. 5 is repeatedly executed at an arbitrary predetermined cycle. Further, here, as shown in FIG. 6, a case where the foreign object 100 remains on the deck board 13 will be described as an example.

  First, the control unit 32 determines whether or not it has been detected that a load greater than or equal to a set value is applied to the pressure sensor cable 31 (step S1).

  In step S <b> 1, it is determined that a user's finger or the like has been sandwiched between the foreign object 100 and the moving handrail 12, and it has been detected that a load greater than the set value has been applied by the pressure sensor cable 31 (that is, Yes). In the case where it has occurred, the control unit 32 outputs a command for stopping the driving of the first escalator 1 to the drive control device 40 (step S2).

Subsequently, the control unit 32 notifies the remote monitoring device 50 that the driving of the first escalator 1 has been stopped (step S3).
Next, the control unit 32 outputs an operation command to the notification unit 33, notifies the escalator user that the driving of the first escalator 1 has stopped (step S4), and performs the process of FIG. finish.

  On the other hand, in step S1, for example, the user's finger or the like is set by the pressure-sensitive sensor cable 31 so that it passes through a place where the foreign object 100 stays without being sandwiched between the foreign object 100 and the moving handrail 12. If it is determined that a load greater than or equal to the value has not been detected (ie, No), the processing of FIG.

As described above, according to the first embodiment, on the deck board arranged along the moving handrail on the outer deck side of the moving handrail that circulates between the entrances and exits, there is a gap between the moving handrail and the deck board. A pressure sensor is provided for detecting that a load greater than the set value has been applied.
Therefore, it is possible to detect foreign matter on the deck board of the passenger conveyor.

  In the first embodiment, as shown in FIG. 3, the pressure-sensitive sensor cable 31 has been described as a planar cable that detects a load in the vertical direction. However, the present invention is not limited to this, and as shown in FIG. 7, the pressure-sensitive sensor cable 31A includes an insulating rubber 311A and two sets of electrodes 312A facing each other through a space inside the insulating rubber 311A. It may be something like that.

  Here, the electrode 312A is provided in a spiral shape along the longitudinal direction of the pressure-sensitive sensor cable 31A. The pressure-sensitive sensor cable 31A detects that a load greater than a set value is applied when the insulating rubber 311A is deformed with respect to an external load and the positive and negative electrodes 312A come into contact with each other. That is, the pressure-sensitive sensor cable 31A can detect loads from all directions.

  In the first embodiment, as shown in FIG. 2, a configuration in which one pressure-sensitive sensor cable 31 is provided between the movable handrail 12 and the deck board 13 on the deck board 13 will be described. did.

Is provided.

  Here, the pressure-sensitive sensor cable 31C (second pressure sensor) operates with a higher load than the pressure-sensitive sensor cable 31B (first pressure sensor). That is, the set value of the pressure-sensitive sensor cable 31B is set to a value that reacts only when a foreign object stays on the deck board 13, for example. Further, as described above, the set value of the pressure-sensitive sensor cable 31C is set to a value that reacts when an object or the like is sandwiched between the foreign object and the moving handrail 12 and a downward load increases.

  At this time, when it is detected that a load greater than or equal to the set value is applied to the pressure-sensitive sensor cable 31B, the control unit 32 confirms that the foreign matter remains on the deck board 13 with respect to the remote monitoring device 50. In addition to the notification, an operation command is output to the notification unit 33 to notify the escalator user that a foreign object remains on the deck board 13 of the first escalator 1. Thereby, while notifying a state to the remote monitoring apparatus 50, a user can be alerted.

  Further, the control unit 32 detects the first escalator with respect to the drive control device 40 when it is detected that a load greater than the set value is applied to the pressure sensor cable 31C after the pressure sensor cable 31B is operated. A command to stop the driving of the first escalator 1 is output, the remote monitoring device 50 is notified that the driving of the first escalator 1 has been stopped, and the notification unit 33 drives the escalator 1 to the user of the escalator. Notify that has stopped. Thus, the escalator can be stopped promptly when a user's finger or the like is caught between the foreign object and the moving handrail 12 after calling attention.

  In addition, the control unit 32 continues the state where it is detected that a load greater than the set value is applied to the pressure sensor cable 31, the pressure sensor cable 31A, or the pressure sensor cable 31C for a predetermined time. In this case, a command for stopping the driving of the first escalator 1 may be output to the drive control device 40. Thereby, it is possible to prevent the escalator from being frequently stopped due to the influence of noise or the like.

  Further, in the first embodiment, it has been described that the pressure-sensitive sensor cable 31 is provided between the movable handrail 12 and the deck board 13 on the deck board 13 as shown in FIG. However, the present invention is not limited to this, and the pressure-sensitive sensor cable may be provided on the guard rail 14. Depending on the shape of the foreign matter, the foreign matter can be detected using a pressure-sensitive sensor cable provided on the guard rail 14.
