Embodiment 1 FIG.
1 is a side view showing an escalator according to Embodiment 1 of the present invention. 2 is a cross-sectional view taken along line II-II in FIG. In the figure, a main frame 1 is provided between an upper landing 2 and a lower landing 3. The main frame 1 supports a plurality of steps (steps) 4 connected endlessly. Further, a pair of balustrades 5 extending along the longitudinal direction of the main frame 1 are erected on the main frame 1. An endless moving handrail 6 is provided at the periphery of each balustrade 5. Each step 4 and each moving handrail 6 are circulated and moved between the upper landing 2 and the lower landing 3 in synchronism with each other by the driving force of a driving device (not shown) disposed in the main frame 1.

  The endless path through which each moving handrail 6 is circulated is located in the forward section where the movable handrail 6 is moved along the periphery of the balustrade 5 and below the forward section, and the movable handrail 6 moves within the main frame 1. The return route section is made up of.

  The balustrade 5 is arranged on both sides of each step 4 in the width direction. The balustrade 5 includes a balustrade body 7 including a design panel, and a handrail guide 8 that is provided at a peripheral portion of the balustrade body 7 and guides the moving handrail 6 that moves in the forward section.

  The handrail guide 8 includes an engaging portion 9 that engages with the moving handrail 6 in a direction perpendicular to the moving direction of the moving handrail 6, and a fixing portion 10 that is fixed to the balustrade body 7 and supports the engaging portion 9. Have.

  The cross-sectional shape of the moving handrail 6 is substantially C-shaped. Moreover, the moving handrail 6 is attached to the handrail guide 8 so that the engaging part 9 may be wrapped. This prevents the moving handrail 6 from coming off the handrail guide 8.

  The handrail guide 8 is provided with a plurality of pressure sensors (pressure detectors) 11 for detecting the distribution of pressure that the handrail guide 8 receives from the moving handrail 6. The pressure sensors 11 are arranged at intervals from each other in the length direction of the handrail guide 8. Each pressure sensor 11 is disposed between the moving handrail 6 and the handrail guide 8. In this example, each pressure sensor 11 is provided on the upper surface of the engaging portion 9. Each pressure sensor 11 has a sheet shape.

  Information from each pressure sensor 11 is transmitted to a control device 12 that controls the operation of the escalator. The control device 12 calculates the distribution of pressure that the handrail guide 8 receives from the moving handrail 6 based on the information from each pressure sensor 11, and determines whether or not the calculated pressure distribution is abnormal.

  Here, FIG. 3 is a perspective view showing the pressure distribution in the moving handrail 6 of FIG. 1, and FIG. 3 (a) shows a pressurizing portion when a passenger attaches one hand to the moving handrail 6. 3 and FIG. 3B are views showing a pressurizing portion when the passenger holds the moving handrail 6 with both hands, and FIG. 3C shows the pressing portion when a load is placed on the moving handrail 6. FIG. When the passenger's posture is a normal riding posture, as shown in FIG. 3A, the pressurizing portion 13 of the moving handrail 6 is in the range of the palm of one passenger.

  On the other hand, when the passenger is standing outside the railing 5 with the moving handrail 6 held by both hands, the pressurizing portion 14 of the moving handrail 6 continues as shown in FIG. It is in the range of two palms. When a large load is placed on the moving handrail 6 by the passenger, as shown in FIG. 3C, the pressure portion 15 of the moving handrail 6 is in a range wider than the range of two palms.

  That is, the range of the pressure part in the moving handrail 6 differs depending on whether or not the passenger is riding normally. It is wider when you are riding on a car, etc. than when you are riding normally.

  Therefore, whether or not there is an abnormality in the pressure distribution is determined based on whether or not the continuous pressurizing range in which pressure is continuously applied in the length direction of the handrail guide 8 is wider than a preset reference range. That is, when the continuous pressurization range is the same as the reference range or narrower than the reference range, the control device 12 performs a normal determination that the pressure distribution is normal, and the continuous pressurization range is less than the reference range. When it is wide, it is determined that there is an abnormality in the pressure distribution. In this example, the control device 12 makes a normal determination when none of the pressure sensors 11 arranged on both sides of the pressure sensor 11 that detects pressurization detects pressure, and pressures adjacent to each other. When any of the sensors 11 detects pressurization, an abnormality is determined.

  The escalator is provided with a speaker (reporting device) 16 capable of generating sound under the control of the control device 12. The speaker 16 generates an alarm under the control of the control device 12 when the control device 12 determines that the pressure distribution detected by each pressure sensor 11 is abnormal. In this example, the speaker 16 generates a warning by giving a voice warning such as “Please take the correct riding posture” to the passengers on the step 4. This alerts the passengers.

  The control device 12 controls the speaker 16 so as to continue generating the alarm when the abnormality determination is performed. In addition, after the abnormality determination, the control device 12 controls the speaker 16 to stop the generation of an alarm when the abnormality determination is canceled before a predetermined time elapses. Furthermore, after performing the abnormality determination, the control device 12 controls the drive device to stop the operation of the escalator when the abnormality determination is continuously performed even after a predetermined time has elapsed.

  Next, the operation will be described. During operation of the escalator, the control device 12 constantly determines whether or not there is an abnormality in the pressure distribution in the handrail guide 8 based on information from each pressure sensor 11. When the pressure distribution is normal, normal operation of the escalator is continued under the control of the control device 12.

  When the controller 12 determines that the pressure distribution is abnormal, an alarm for alerting the passenger is generated from the speaker 16 under the control of the controller 12. After this, if the abnormality determination by the control device 12 is not canceled even after a predetermined time has elapsed, the operation of the escalator is stopped by the control of the control device 12 while the alarm from the speaker 16 continues to be generated. .

  If the abnormality determination by the control device 12 is canceled before the predetermined time elapses, alarm generation from the speaker 16 is stopped and normal operation is continued.

  In such an escalator, a plurality of pressure sensors 11 for detecting the distribution of pressure received by the handrail guide 8 from the moving handrail 6 are provided in the handrail guide 8, and the control device 12 is based on information from each pressure sensor 11. Since it is determined whether or not there is an abnormality in the pressure distribution, for example, when a passenger on the escalator gets out of the railing 5 or a large load is placed on the moving handrail 6 Thus, it is possible to more reliably detect a situation in which an accident during boarding is likely to occur, and it is possible to prevent the occurrence of an accident when a passenger is on the escalator.

  In addition, an alarm is generated from the speaker 16 when an abnormality in the pressure distribution is determined by the control device 12, so that the passengers on board can be alerted and the occurrence of an accident can be prevented. Can be further planned.

  Further, the control device 12 stops the operation of the escalator when the abnormality determination is continued even after a predetermined time has elapsed after performing the abnormality determination that the pressure distribution in the handrail guide 8 is abnormal. Therefore, it is possible to further prevent the occurrence of an accident when a passenger is in the vehicle.

  In the above example, the alarm when the abnormality determination is made by the control device 12 is only a warning by sound from the speaker 16, but a display is provided around the escalator, and a warning by display on the display is provided. May also be performed.

Embodiment 2. FIG.
FIG. 4 is a side view showing an escalator according to Embodiment 2 of the present invention. In the figure, the escalator is provided with a monitoring camera (photographing device) 21 for photographing a passenger on Step 4. The monitoring camera 21 is controlled by the control device 12.

  The operation of the monitoring camera 21 is stopped during normal normal operation. In addition, the monitoring camera 21 is operated when the abnormality determination is continued even after a predetermined time has elapsed after the abnormality determination that the pressure distribution of the handrail guide 8 is abnormal is performed by the control device 12. Under the control of the control device 12, photographing for monitoring the passenger's boarding state is started.

  The control device 12 determines whether or not to stop the operation of the escalator based on information from the monitoring camera 21. In other words, the control device 12 performs image processing based on the image information from the monitoring camera 21 and, based on the processing result, determines that the situation is likely to cause an accident for a passenger on the escalator. The operation of the escalator is continued when it is determined that the operation is stopped and an accident is avoided. Other configurations are the same as those in the first embodiment.

  Thereafter, the control device 12 processes the image information from the monitoring camera 21, and determines whether or not an accident is likely to occur for a passenger on board. When it is determined by the image processing performed by the control device 12 that an accident is likely to occur for a passenger on board, the operation of the escalator is stopped by the control of the control device 12. When it is determined that an accident is avoided, the operation of the escalator is continued under the control of the control device 12.

  In such an escalator, after the abnormality determination by the control device 12 is performed, when the abnormality determination is continued even after a predetermined time has passed, photographing for monitoring a passenger's boarding state is performed. 21 is started, it is possible to more accurately detect the situation of passengers on board, and to more reliably prevent accidents during boarding. In addition, since the photographing time by the monitoring camera 21 can be shortened, the life of the monitoring camera 21 can be extended.

  In the above example, the processing of the image information from the monitoring camera 21 is performed by the control device 12, but the monitoring camera is attached to the monitor provided in the management room for managing the operation of the escalator. The video imaged by 21 may be displayed. In this way, it is possible for the supervisor in the control room to determine whether or not an accident is likely to occur for passengers on board, and the handling of the escalator can be made more flexible.
