  With the above-described configuration, the escalator run-down warning device can detect the vibration generated in the tracking rail by the acceleration sensor and issue a warning directly to the passenger when the passenger runs down the escalator. That is, the passenger who runs down the escalator generates vibration in the escalator step depending on the weight of the escalator and the weight of the belongings. This vibration is transmitted to the tracking rail on which the escalator step is supported. In particular, the vibration that the tip of the step receives is directly transmitted to the tracking rail, so that the vibration can be accurately picked up. Therefore, the acceleration of this vibration can be detected by providing an acceleration sensor on the tracking rail. Further, the vibration characteristics generated by passengers running down the escalator are characteristic, and can be determined by comparing with the vibration characteristics measured by the acceleration sensor when a person runs down the escalator. Further, the speed at which the passenger runs down the escalator can be detected from the vibration characteristics, and it can be determined whether or not the vehicle is dangerous.

  In the escalator run-down alarm device, it is preferable that a plurality of acceleration sensors are provided at substantially the center of the position where the tracking rail is supported by the truss of the escalator. As a result, the vibration generated when the passenger runs down the escalator can be measured at a position where the amplitude of the vibration of the tracking rail is large, and the vibration is generated when the passenger runs down the escalator using a plurality of acceleration sensors. Can be accurately captured.

  The escalator run-down warning device is configured so that the passenger movement grasping unit grasps that the escalator is in a descending operation based on a signal from the escalator control device, and from the moving direction of the vibration source specified by the measurement of a plurality of acceleration sensors. It is preferable to grasp that the passenger is going down the escalator. Thereby, it can be grasped whether the escalator is going down or going up, whether the passenger is going down or going up. In particular, it is possible to accurately grasp the descending of the descending escalator by a passenger with high risk.

  In the escalator run-down warning device, the vibration characteristic storage unit evaluates and stores the periodic acceleration peak value measured by the acceleration sensor and the vibration characteristic generated in the tracking rail from the period, and the vibration source determination unit From the vibration speed measured by the acceleration sensor, the peak value of periodic acceleration and the period thereof are determined to be the predetermined vibration characteristics stored in the vibration characteristic storage unit, and the passenger speed calculated from the acceleration period is used. It is preferable to determine that the passenger is running down the escalator at a predetermined speed or higher. As a result, by paying attention to the peak value of periodic acceleration and its period among the vibration characteristics when the passenger is running down the escalator, it is accurately determined that the passenger is running down the escalator at a predetermined speed or more.

As a result, depending on the age of passengers such as children and adults with different weights and amount of exercise, or gender differences in gender, the cyclic acceleration peak value and the pattern of that cycle are categorized, and for a wide range of passengers Can alert escalators.

  In the escalator run-down warning device, the acceleration sensor is provided in a pair with the left and right tracking rails of the escalator, and the vibration source determination unit determines whether the passenger is informed by comparing the peak values of acceleration detected by the left and right acceleration sensors. It is preferable to determine which position in the width direction of the escalator is running down. Thereby, it can be judged whether the passenger is running down the edge part or center part of the width direction of an escalator.

  Further, the escalator run-down warning device is dangerous to the sound generator when the vibration source determination unit determines that the passenger is running the end of the escalator in the width direction at a predetermined speed or higher. If it is determined that the passenger is running down the center in the width direction of the escalator at a predetermined speed or higher, a warning that the sound generator is dangerous is issued. Is preferably issued. In general, the risk of running down the center is higher than the risk of running down the end, so that warning can be made in accordance with the risk of running down the escalator.

  As described above, according to the escalator run-down warning device according to the present invention, it is possible to easily determine that the passenger is running down the escalator at a predetermined speed or more and to issue a warning directly to the passenger. It becomes.

  Hereinafter, embodiments of an escalator run-down alarm device according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a schematic configuration of one embodiment of the escalator running warning device. The escalator run-down alarm device 1 includes an acceleration sensor 2, a vibration characteristic storage unit 3, a passenger movement grasping unit 4, a vibration source determination unit 5, a sound generator 6, and an alarm notification unit 7.

  In FIG. 2, the step 20 of the escalator 13 and its support part are shown. A driving roller 21 and a follower roller 10 are attached to each step 20 of the escalator 13. Each step 20 is supported by the drive rail 22 via the drive roller 21 and supported by the follower rail 9 via the follower roller 10. Further, the step chain 23 is driven by a driving device (not shown) to drive the step 20.

  The acceleration sensors 2 a, 2 b, 2 c are provided on the follower rail 9 of the escalator 13 and measure the acceleration of vibration generated on the follower rail 9. This is because the follower roller 10 is disposed below the tip of step 20, so that an impact by a passenger running down step 20 is easily transmitted to the follower rail 9 via the follower roller 10. A plurality of acceleration sensors 2 a, 2 b, and 2 c are provided at substantially the center of the position where the tracking rail 9 is supported by the escalator truss 11. The follower rail 9 is a beam supported by the escalator truss 11 at a predetermined pitch. Therefore, the maximum deflection is likely to occur at the approximate center of the truss support point 14 due to the impact of the passenger. That is, it is desirable to measure the acceleration of the vibration generated in the tracking rail 9 due to the impact of the passenger at the substantially central portion of the truss support point 14.

  The vibration characteristic storage unit 3 stores vibration characteristics generated in the tracking rail 9 by the acceleration sensors 2a, 2b, and 2c when a measurement person or the like runs down the escalator 13 that is on a trial basis. That is, the vibration characteristic storage unit 3 measures the acceleration generated in the tracking rail 9 by the acceleration sensors 2a, 2b, and 2c when running down the down escalator 13, and models and stores the vibration characteristic in advance. Keep it. The vibration characteristic means a peak value of acceleration and its cycle. That is, the passenger who runs down the escalator 13 goes down step 20 with a substantially constant rhythm. Therefore, periodic acceleration peaks are measured in the acceleration sensors 2a, 2b, and 2c. And the vibration characteristic is seen in the peak value and the period of the acceleration which generate | occur | produce in the time from the start point of the escalator 13 to an end point. The vibration characteristic storage unit 3 models and stores this vibration characteristic.

  The passenger movement grasping unit 4 grasps whether or not the passenger is moving on the descending escalator 13. That is, the passenger movement grasping unit 4 grasps that the escalator 13 is in the descending operation by a signal from the control device 8 that controls the operation of the escalator 13. And it is grasped | ascertained whether the passenger is going up or down the escalator 13 from the moving direction of the vibration source specified by the measurement of several acceleration sensor 2a, 2b, 2c. As described above, the passenger movement grasping unit 4 can grasp whether or not the passenger is going down the escalator 13 and can issue a warning only when the passenger is going down the escalator 13.

  The vibration source determination unit 5 determines whether or not the periodic acceleration peak value and the period among the vibration characteristics measured by the acceleration sensor 2 are vibration characteristics stored in the vibration characteristic storage unit 3. That is, in the morning rush hour, there may be a case where the row of stationary passengers and the row slowly descending the escalator 13 are divided. In this case, there is not much danger in descending the descending escalator 13. This is because the periodic acceleration peak value and its period among the vibration characteristics measured by the speed sensor 2 are clearly different from those when the passenger runs down the escalator 13. Further, the vibration source determination unit 5 determines whether the passenger is running down the escalator 13 at a predetermined speed or higher from the passenger speed calculated from the acceleration cycle.

  Further, the vibration characteristic storage unit 3 stores the peak value of the periodic acceleration measured for each pattern of the combination of the passenger's age and sex, and the period thereof. That is, for example, there is a tendency that the peak value of periodic acceleration, which is a vibration characteristic, and the period thereof vary depending on the age of passengers such as children, adults, and elderly people, and gender differences. Therefore, the peak value of the periodic acceleration measured for each passenger age and gender combination pattern and its period are modeled and stored in the vibration characteristic storage unit 3.

  Then, the vibration source determination unit 5 includes a predetermined peak range of any vibration characteristic pattern stored in the vibration characteristic storage unit 3 in which the peak value of the periodic acceleration among the vibration characteristics measured by the acceleration sensor 2 and the period thereof are stored. If it is within, it is determined that the vibration is generated when a passenger belonging to the age and sex runs down the escalator 13 at a predetermined speed or higher.

  As shown in FIG. 1, the sound generator 6 is provided in the vicinity of the escalator 13, for example, on the upper surface of the escalator 13. Then, when the alarm source determination unit 7 determines that the vibration source determination unit 5 is running down the escalator 13 at a predetermined speed or higher, the voice generator 6 uses the voice generator 6 for the passenger, for example, Alerts such as “Dangerous”. In this case, the vibration source determination unit 5 recognizes the position of the passenger running down the escalator 13 from the measurement of the acceleration sensors 2a, 2b, and 2c, and issues a warning to the sound generator 6 closest to the passenger's position. Let
