  FIG. 1 is a schematic side view showing the structure of a passenger conveyor in the first embodiment. FIG. 2 is a schematic plan view for explaining the positional relationship between the arrangement of the optical sensors and the passengers in the first embodiment. In the passenger conveyor of the first embodiment shown in FIG. 1 and FIG. 2, the entrance area A composed of the exit floor board 5 and the horizontal moving part of the escalator, and the boarding composed of the entrance floor board 4 and the horizontal moving part of the escalator. The following description will be given on the assumption that there is an inclined moving part B between the exit area C, the exit area A, and the entrance area C, and a passenger who falls in the exit area A is detected. When the horizontal moving part of the escalator is long, the horizontal moving part is detected, and when the horizontal moving part is short, the fallen passenger is detected even in the region including the end of the inclined moving part B.

  In FIG. 1, an escalator that is a passenger conveyor and a moving sidewalk are provided with a plurality of endlessly connected steps 1, and balustrades 3 that support moving handrails 2 are erected on the left and right sides of these steps 1. The The balustrade 3 has a balustrade panel and a skirt portion 30 provided so as to cover the lower part of the balustrade panel. The skirt portion 30 on the inside (step 1 side) of the balustrade 3 is a skirt guard arranged perpendicularly to the side of the step 1, and an inner deck provided between a lower part of the balustrade panel and the skirt guard, and a part thereof being inclined. And have. As shown in FIG. 2, the left side of the balustrade 3 as viewed from the lower side (the entrance side) is the balustrade 3A and the right side is the balustrade 3B.

Further, in FIG. 1, the passenger is transported from the entrance floor board 4 to the exit floor board 5 during the descent operation by the synchronous movement of the step 1 and the moving handrail 2. During the ascending operation, the passenger is conveyed from the entrance floor board 5 to the exit floor board 4. The chain 6 that connects the step 1 endlessly is wound around the sprockets 7 and 8. Further, a driving device 11 having a motor 9 and a speed reducer 10 is provided at the lower part of the entrance floor plate 4 to drive the sprocket 8 through the driving chain 12 to drive the chain 6 and step 1. It is like that.
In the present specification, the term “step” includes a step board of a moving sidewalk.

  In FIG. 2, the leg of an upright passenger in the range from the balustrade end portion on the entrance side of the left balustrade 3A of the passenger conveyor to the balustrade end portion on the exit side through the inclined moving portion B of the passenger conveyor. The projectors 14-1 to 14-N of the transmissive photoelectric sensor are installed at regular intervals L at a low position corresponding to the unit. Further, a projector 14-1 is positioned at a low position corresponding to the leg of an upright passenger in a range from the balustrade end portion on the right balustrade 3 </ b> B to the balustrade end portion on the exit gate side via the inclined moving portion B. ˜14-N, light receiving devices 15-1 to 15-N of the transmission type photoelectric sensors are installed at regular horizontal intervals L, respectively.

  A passenger detection sensor is configured by receiving the photoelectric beams 16-1 to 16-N output from the projectors 14-1 to 14-N by the light receivers 15-1 to 15-N, respectively. Passenger detection is performed by the light shielding, and a sensor light shielding signal is output. All of the sensor light shielding signals from the light receivers 15-1 to 15-N are individually input to the control device 13, or the sensor light shielding signals from the light receivers 15-1 to 15-N It may be divided into three groups of “inclination moving part” and “alighting area” and input to the control device 13.

  In order to prevent the detection failure of passengers by the photoelectric sensor, it is preferable that the constant horizontal interval L is shorter than that of a general child's leg, but the number of installed photoelectric sensors and steps are moving. In consideration of this, a width of one or two steps may be set.

FIG. 3 is a block diagram illustrating a system configuration of the photoelectric sensor, the control device, the drive device, and the alarm device of the passenger conveyor according to the first embodiment of the present invention.
In FIG. 3, sensor light shielding signals of the light receivers 15-1 to 15 -N are input to the control device 13, and among them, the sensor light shielding signal of the light receiver 15 (such as “15-N”) in the exit area A. Is input to the passenger fall determination unit 20 to determine whether the passenger falls in the exit area A. The passenger fall determination time, which is a passenger fall determination condition in the exit area A by the passenger fall determination unit 20, stays at the same position for a long time with respect to walking speeds of general passengers, elderly people, and walking disabled persons as described later. Set assuming that The alarm control unit 23 receives the passenger fall determination of the passenger fall determination unit 20, and an alarm is issued from the alarm device 17 or an alert broadcast is performed by an alarm command from the alarm control unit 23.

  Moreover, the sensor light-shielding signal of at least one light receiver 15 in the inclined moving part B and the entrance area C is input to the passenger absence determination part 21 in use of the control device 13, and other passengers using the passenger conveyor are in use. Presence / absence is determined. The passenger conveyor operation control unit 22 receives the passenger fall determination of the passenger fall determination unit 20 and the in-use passenger absence determination from the in-use passenger absence determination unit 21, outputs a stop instruction for the passenger conveyor, and drives the passenger conveyor. 11 is controlled to stop the operation of the passenger conveyor. In addition, the operation control unit 22 has a passenger fall determination of the passenger fall determination unit 20, but there is no use passenger absence determination of the in-use passenger absence determination unit 21 (when there is another passenger in use), the passenger The conveyer stop command is not output, and the passenger conveyor drive device 11 continues the operation of the passenger conveyor.

  FIG. 4 is a flowchart of the operation control of the passenger conveyor at the time of detecting the passenger falling in the first embodiment. In the following, the operation control of the passenger conveyor at the time of detecting the passenger falling of the present embodiment will be described using the flowchart shown in FIG.

  In step 42, it is determined whether the passenger conveyor is in operation.

  Next, in step 43, the fallen passenger 18 shown in FIG. 2 shields the photoelectric beam 16 (“16-N” or the like) in the exit area A and receives the light receiver 15 (“15” installed in the exit area A). -N "etc.) detects a fallen passenger, and when the sensor shading signal is turned on, the ON state time, that is, the time during which the sensor shading signal is output is determined in advance. It is determined whether or not the determination time has elapsed.

  In step 44, when the ON state of the sensor shading signal output from the light receiver 15 (such as “15-N”) in the exit area A is longer than the passenger fall determination time, the light receiver in the exit area A shown in FIG. The passenger fall determination unit 20 to which 15 (15-N, etc.) sensor shading signal 31 is input determines that the passenger has fallen in the exit area A. The passenger fall determination time of the passenger fall determination condition in the exit area A by the passenger fall determination unit 20 shown in FIG. 3 stays at the same position in a long time with respect to the walking speed of general passengers, elderly people, and walking disabled persons. Set assuming that

For example, the passenger fall determination time can be determined as follows.
First, assuming that the walking speed of elderly people and people with walking disabilities is 0.67m / sec (sec) (normal people walking speed is about 1.5m / sec) and the width of the leg is 0.1m or more, the leg will have a sensor. The time to pass is
“Leg width: 0.1m” ÷ “Walking speed: 0.67m / sec” = 0.15sec.
Taking a margin from 0.15 seconds (sec) of the sensor passage time, the passenger fall determination time is set to 0.50 sec to 2.00 sec, for example.
From the above, in step 44, when the passenger detection time by the light receiver (such as “15-N”) in the exit area A is, for example, a determination time determined between 0.50 sec to 2.00 sec, the passenger Determined to fall.

  If it is determined in step 44 that the passenger falls, in step 45, an alarm is sounded from the alarm device 17 or an alert broadcast is performed in accordance with an alarm command of the alarm control unit 23 of the control device 13 shown in FIG.

  In step 46, when there is no other passenger 19 using the passenger conveyor, the photoelectric beam 16 of the inclined moving part B is not shielded, and all the light receivers 15 installed in the inclined moving part B detect other passengers. It is determined whether or not the state where the sensor light shielding signal is OFF, that is, the passenger absence determination time has elapsed.

  When the sensor light-shielding signals from all the light receivers 15 installed in the inclined moving part B are OFF for more than the passenger absence determination time, in step 47, the sensor light-shielding signals of the light receivers 15 installed in the inclined moving part B are passed. It is determined that there is no other passenger using the passenger conveyor by the passenger absence determination unit 21 in use of FIG. As shown by the solid line 32 in FIG. 3, the passenger absence determination time in the determination condition of the presence or absence of other passengers in use by the passenger absence determination unit 21 in use uses a sensor light shielding signal from the light receiver 15 of the inclined moving unit B. In the case of only doing, in the state where the sensor light shielding signal of all the light receivers 15 installed in the inclined moving part B is OFF, the passenger in use reaches the exit floor board after shielding the last sensor of the inclined moving part B. Maximum time required for passengers (passenger presence time in the inclined moving part B) and maximum time until the passenger enters the entrance area C and shields the first sensor in the inclined moving part B (passenger existing time in the entrance area) ), Whichever is longer, and is set.

  In order to increase the accuracy of the presence / absence determination of the presence of other passengers using the passenger conveyor by the passenger absence determination unit 21 in use, the sensor light-shielding signals of both the inclination moving unit B and the light receiver 15 installed in the entrance area C are controlled. It is good also as determining that there is no other passenger who is using a passenger conveyor when the state which has input into the apparatus 13 and the passenger absence determination part 21 in use has not detected other passengers has passed for a certain period of time. . That is, as indicated by the dotted line 33 in FIG. 3, the sensor light shielding signal may be input to the in-use passenger absence determination unit 21 also from the light receiver 15 (15-1 or the like) in the entrance area. As indicated by the dotted line 33 in FIG. 3, the passenger absence determination time when the sensor light-shielding signal is also input to the in-use passenger absence determination unit 21 from the light receiver 15 (15-1 or the like) in the entrance area C and used. Is in a state where all sensor light shielding signals of the light receivers 15 installed in both the inclination moving part B and the entrance area C are OFF, after other passengers in use shield the last sensor of the inclination moving part B, It may be the maximum time required to reach the landing floor board (passenger presence time of the inclined moving part).

  If the sensor light-shielding signal is not OFF for the passenger absence determination time or longer, in step 48, the in-use passenger absence determination unit 21 determines that there is another passenger 19 in use. At this time, when it is determined that the passenger falls by the passenger fall determination unit 20 in step 44, the operation of the passenger conveyor is continued while the alarm device 17 sounds an alarm or broadcasts an alert. In the event that another passenger 19 in use eventually reaches the exit area, in addition to sounding the alarm device 17 or carrying out an alert broadcast, the presence of a passenger 18 who has fallen down due to the other passenger 19 in use Therefore, it is considered that rescue of the fallen passenger 18 by another passenger 19 in use can be expected.

As described above, continuation of operation is continued without changing speed, continued operation after shifting to decelerating operation, stopped after decelerating operation, stopped, gradually decelerated while continuing operation, etc. When a fallen passenger is detected, the operation of the passenger conveyor is not stopped immediately but is continued in some form.
For example, when the passenger conveyor speed is 30 m / min and the braking is suddenly stopped by braking, the deceleration is 0.6 m / sec ² and the braking distance is 200 mm. the deceleration as ^{0.4m / sec 2 ~0.1m / sec 2} , may be a continuous operation of the distance 300Mm～1300mm.

  If it is determined in step 44 that the passenger fall determination unit 20 determines that the passenger has fallen, and in step 47 that the in-use passenger absence determination unit 21 determines that there is no passenger in use (after determining that there is a passenger, to the determination that there is no passenger) In this case, the passenger conveyor drive device 11 is controlled by the stop instruction of the passenger conveyor operation control unit 22 in step 49 because there is no fear that other passengers who are using the passenger conveyor will be in danger. Immediately stop the operation of the passenger conveyor. The stop at this time may be a sudden stop with a brake that emphasizes urgency, the same emergency stop as when the safety device is operating, or a normal stop operation, but for the safety of passengers entering the entrance area A normal stop operation is preferable. In addition, once the operation is stopped, restarting by starting automatic operation or the like is not performed until the control device is reset.

  1 and 2 are diagrams when the passenger conveyor is lowered, but since the photoelectric sensor has a vertically symmetrical configuration, the passenger conveyor is similarly operated only when the entrance and exit sides are switched up and down during the ascending operation. Can control.

  In addition, in order to improve the accuracy of detection of passenger fall in the exit area by the passenger fall determination unit 20, a state where a plurality of continuous light receivers 15 installed in the exit area A are simultaneously shielded from light is constant for a certain period of time. When it has elapsed, it may be determined that the passenger has fallen at the exit. That is, for example, from the plurality of light receivers 15 (two light receivers such as “15-N” and “15- (N-1)”) in the exit area of FIG. It is recommended that passengers fall. As a result, passengers who have just stopped in the exit area A can be distinguished not only by the sensor light shielding signal from only one light receiver but also by the sensor light shielding signals from a plurality of light receivers.

  In addition, in order to raise the precision of the passenger fall determination in the exit area by the passenger fall determination part 20, the passenger detection sensor (set of the light projector 14 and the light receiver 15) of the exit area is the low position of the balustrade 3 You may install in the lower position of the balustrade 3 above the skirt part 30, or the upper position of the skirt part 30 of the part which does not rub against when a step goes up and down.

  In addition, the passenger detection sensor for detecting a passenger can be used for a fall detection device that detects whether the passenger falls in the exit area and whether there is an inclined moving part using the passenger conveyor or other passengers in the entrance area. A sensor other than the sensor (for example, a reflective photoelectric sensor) may be used. Furthermore, an area sensor may be used as a passenger detection sensor for detecting a passenger in at least one of the entrance area, the inclined moving part, and the exit area.

In addition, if it is a configuration that can determine the fall of passengers in the exit area and the presence or absence of other passengers in the inclined moving part or passenger area using the passenger conveyor, the passenger conveyor A surveillance camera may be installed as a passenger detection sensor for detecting a passenger at the entrance / exit area and the inclined moving part, and image analysis of the camera may be used.
In any case, the control device 13 can determine the passenger's fall state and the presence or absence of other passengers in use based on the signal from the passenger detection sensor.

  In addition, even if it is the structure which simplified the structure of the passenger detection sensor and abbreviate | omitted the sensor of the inclination moving part of a passenger conveyor, the light receiver 15 (15-1 grade | etc.) Of a boarding area determines the determination time of the presence or absence of a passenger. After the passenger is not detected (passenger is not detected), the time corresponding to the passenger getting on the passenger conveyor and then getting off is calculated (from the speed of the passenger conveyor and the length of the inclined moving part). (Calculation) If set, the presence or absence of a passenger can be easily determined.

  In the case of an inverter-controlled passenger conveyor, when it is determined that there are other passengers in use at the time of passenger fall detection, a stop operation is started while continuing the operation, but it is also safe to prevent a sudden stop. It is possible to stop more slowly than the emergency stop at the time of emergency stop during the operation of the device, so that the passenger does not fall down by the inverter control.

In the present invention, when a passenger who has fallen in the exit area of the passenger conveyor is detected, if there are other passengers using the passenger conveyor, the operation of the passenger conveyor is continued. Continuation is to continue operation without changing speed, continue operation after shifting to deceleration operation, stop operation after decelerating operation and continue operation such as stop and stop gradually while continuing operation This means that the operation of the passenger conveyor is not immediately stopped when a fallen passenger is detected.
By decelerating, other passengers who are using the passenger conveyor will not be afraid of a secondary fall by sudden stop, and there will be time to find a fallen passenger. There is an effect that it is possible to afford time for dealing with a fallen passenger. In particular, in the ascending operation, it is difficult to see passengers who have fallen in the exit area from under the inclined moving part, so that further time is required. Furthermore, the speed reduction operation is gradually performed, so that a sense of security is given to other passengers. In such an operating state, there is no safety concern even if the passenger conveyor is stopped even when other passengers are in the inclined moving part or the entrance area.
