[0025] (2) Structure of the boarding suppression device 5

[0026] Next, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The boarding suppression device 5 for suppressing passengers from boarding the escalator 10 will be described. The control device 50 has both the function of a control unit for the escalator 10 and the function of a control unit for the boarding suppression device 5.

[0027] like Figure 2 As shown in the block diagram of , in order to function as a control unit of the escalator 10, a drive circuit 51 including an inverter circuit for controlling the rotation direction and rotation speed of the motor 20 is connected to the control device 50. The motor 20 and the electromagnetic brake 23 for stopping the rotation of the motor 20 are connected to the drive circuit 51.

[0028] In addition, in order to serve as the control unit of the boarding suppression device 5, the control device 50 is connected to a camera 64; an LED 66, an LED lighting circuit 68, a passenger sensor 52, and a speaker 54 are arranged on the upper layer side; and an LED 70, an LED lighting circuit 72, a passenger sensor 56 and a speaker 58 are arranged on the lower layer side.

[0029] like Figure 2 , Figure 4 and Figure 5 As shown, in order to function as a display unit of the boarding suppression device 5 , a plurality of LEDs 66 are provided in a grid pattern (not shown) over the entire upper surface of the boarding and descending board 32 of the upper stage. Figure 2 The LED lighting circuit 68 shown can display an image by controlling the lighting, extinguishing, color and brightness of each LED 66. In addition, in order to function as a display unit of the boarding suppression device 5, a plurality of LEDs 70 are arranged in a grid pattern on the entire upper surface of the boarding and landing board 34 of the lower layer. Figure 2 The LED lighting circuit 72 shown can display an image by controlling the lighting, extinguishing, and brightness of each LED 70 .

[0030] The passenger sensor 52 provided on the upper floor is composed of a light emitting unit and a light receiving unit. The light emitting unit is provided on the apron plate 44 above the left end of the comb plate 60 provided on the upper floor, and the light receiving unit is provided on the apron plate 44 above the right end of the comb plate 60. Light such as infrared rays is always transmitted from the light emitting unit to the light receiving unit. When the infrared rays are blocked when a passenger gets on the step 30, the passenger sensor 52 detects that the passenger has gotten on the step 30. Similarly, the passenger sensor 56 on the lower floor is provided with a light emitting unit and a light receiving unit respectively on the apron plates 44, 44 above the left and right end portions of the comb-shaped unit 62 provided on the lower floor to detect passengers.

[0031] like Figure 1 As shown, the camera 64 is installed on the ceiling surface 4 of the building 1 located above the escalator 10. The camera 64 shoots the escalator 10 from above and can shoot passengers riding on the steps 30 of the escalator 10 and passengers on the boarding and landing boards 32 and 34. In addition, the control device 50 can perform image analysis on the passengers based on the dynamic images (or still images) shot by the camera 64.

[0032] (3) Description of the Operation of the Ride-Through Suppression Device 5

[0033] The boarding suppression device 5 of this embodiment is used to suppress the boarding of passengers. Figure 1 The passengers shown in the figure are spaced appropriately from each other. Figure 1 As shown, when the steps 30 are lowered, the camera 64, the LED 66 disposed on the upper floor boarding plate 32, the LED lighting circuit 68, the passenger sensor 52, and the speaker 54 are used to suppress the passengers from boarding.

[0034] More specifically, if Figure 4 As shown in (a), when no one is riding on the escalator 10, the control device 50 uses the LED lighting circuit 68 to display a strip-shaped safety area A extending in the front-to-back direction from the comb plate 60, i.e., the boundary between the front end of the boarding and descending plate 32 and the steps 30 (hereinafter referred to as the "boundary") toward the rear of the upper surface of the boarding and descending plate 32 using LEDs 66. The safety area A causes all of the multiple LEDs 66 arranged in a grid pattern to light up in green, indicating an area within which passengers can board. The control device 50 also always performs image analysis on the dynamic image captured by the camera 64 to detect whether a passenger has boarded the boarding and descending plate 32. In addition, in Figure 4 , Figure 5 In FIG. 1 , the range of the landing platform 32 indicated by dots is the safety area A. FIG.

[0035] Then, if Figure 4As shown in (b), when a passenger J1 walks into the safety area A on the upper surface of the boarding and alighting platform 32 and reaches the comb plate 60 (boundary), the passenger sensor 52 detects it. Then, the control device 50 uses LED 66 to display a prohibited area K with a spacing length L (for example, about 1m) for ensuring a predetermined spacing between passengers on the boarding and alighting platform 32 in red. Figure 4 , Figure 5 In the figure, the range of the boarding and landing platform 32 covered by the hatching is the prohibited area K. The prohibited area K is a space of a distance length L from the passenger J1 who wants to board the steps 30 to the rear as a space required to obtain an appropriate distance d, and is an area indicating that other passengers are prohibited from boarding, and is displayed in red to make it easy to understand that it is the prohibited area K. In addition, the control device 50 guides the passengers with a voice "Please do not enter the red prohibited area" from the speaker 54 on the upper floor as needed.

[0036] Then, if Figure 4 (c) and Figure 4 As shown in (d), when passenger J1 takes the step 30, the step 30 moves toward the lower floor at a specified speed (e.g., a rated speed V of 30 m / min). On the other hand, when passenger J1 completely moves from the boarding and alighting platform 32 to the step 30, the passenger sensor 52 no longer detects passenger J1, so the timer located inside the control device 50 starts timing from this moment t0. In addition, when the step 30 boarded by passenger J1 moves downward at a rated speed V, the control device 50 obtains information about the rated speed V from the drive circuit 51, and shortens the length of the prohibited area K extending in a strip shape on the upper surface of the boarding and alighting platform 32 in the front-to-back direction in accordance with the rated speed V. As a result, the rear end of the prohibited area K approaches the comb plate 60 (boundary). On the other hand, the control device 50 extends the length of the safety area A in the front-to-back direction by the amount by which the length of the prohibited area K on the upper surface of the boarding and alighting platform 32 in the front-to-back direction is shortened.

[0037] Then, if Figure 4 As shown in (e), the timer starts counting from time t0, and when the interval ensuring time T has passed, the control device 50 ends the display of the prohibited area K and displays the entire upper surface of the boarding and landing board 32 as the safe area A. Figure 1As shown, the "interval ensuring time T" is the time for making the distance between passengers on the steps 30 become the appropriate interval d. When the appropriate interval d is set to, for example, 2m and the rated speed V of the escalator 10 is set to 30m / min (=0.5m / sec), the interval ensuring time T=d / V=2 / 0.5=4(sec). Therefore, the control device 50 shortens the prohibited area K from the interval length L and ends the display at T=4 seconds. In addition, as the speed v for shortening the prohibited area K, when L=1m, v=L / T=L*V / d=0.25(m / sec). By shortening at this speed v, when the rear end of the prohibited area K reaches the comb plate 60 (boundary), the display of the prohibited area K ends.

[0038] However, if Figure 5 As shown in (a), the control device 50 sometimes detects from the dynamic image of the camera 64 that after one passenger J1 has boarded the step 30, another passenger J2 has boarded the prohibited area K before the interval ensuring time T has passed. Hereinafter, the other passenger J2 is referred to as "queue-jumping passenger J2".

[0039] At this time, if Figure 5 As shown in (b), the control device 50 displays the prohibited area K of the interval length L again from the comb plate 60 (boundary) to the rear. Then, the speaker 54 is used to warn the passenger J2 who cuts in the prohibited area K with a voice "No entry to the red prohibited area". When the queue-cutting passenger J2 comes out of the prohibited area K according to the instruction of the voice, the queue-cutting passenger J2 will not approach the passenger J1.

[0040] However, if Figure 5 (c) Figure 5 (d) Figure 5 As shown in (e), when the queue-jumping passenger J2 does not follow the instruction of the voice and rides on the step 30 from the prohibited area K, the passenger sensor 52 detects the queue-jumping passenger J2 once, and then, from the time t0 when it is no longer detected, the control device 50 starts the timing of the timer, and from this time t0, the length of the prohibited area K is shortened according to the rated speed V of the escalator 10. In this way, when there is a passenger following the queue-jumping passenger J2, the interval between the queue-jumping passenger J2 and the subsequent passenger can be maintained at an appropriate interval d.

[0041] Even if another passenger enters the safety area A of the boarding and alighting platform 32, the control device 50 does not change the display of the prohibited area K or the safety area A but displays it as it is. And, only when another passenger enters the prohibited area K, the above control is performed assuming that the queue-jumping passenger J2 is the one who enters the prohibited area K.

[0042] In addition, the above example illustrates the situation when the step 30 is descending, but when the step 30 is ascending, the boarding suppression device 5 uses the camera 64, the LED 70 of the boarding plate 34 arranged on the lower side, the LED lighting circuit 72, the passenger sensor 56, and the speaker 58 to suppress the boarding of passengers.

[0043] (4) Operation sequence of the boarding suppression device 5

[0044] Next, refer to Figure 3 The flowchart illustrates the operation sequence of the boarding suppression device 5.

[0045] In step S1, the escalator 10 starts descending. The steps 30 descend at a rated speed V. At the same time, the passenger sensor 52 on the upper floor is activated, and the camera 64 on the ceiling surface 4 detects passengers on the upper floor board 32. Then, the process proceeds to step S2.

[0046] In step S2, if Figure 4 As shown in (a), since there are no passengers on the upper deck 32, the control device 50 displays a green safety area A on the entire area of ​​the deck 32. Then, the process proceeds to step S3.

[0047] In step S3, if Figure 4 As shown in (b), passenger J1 walks to the comb plate 60 located at the front end of the boarding and alighting plate 32. If the passenger sensor 52 detects passenger J1, the process proceeds to step S4 (case y). If passenger J1 is not detected, the process continues to step S3 (case n).

[0048] In step S4, Figure 4 As shown in (b), the control device 50 displays a red prohibited area K with a spacing length L from the comb plate 60 (boundary) to the rear on the upper surface of the boarding and landing platform 32, and displays a safe area A behind the rear end of the prohibited area K. Then, the process proceeds to step S5.

[0049] In step S5, Figure 4 As shown in (c), when passenger J1 completely enters the stairs 30 from the boarding and alighting platform 32 and the passenger sensor 52 no longer detects passenger J1, the process proceeds to step S6 (case y). If passenger J1 is still detected, the process continues to step S5 (case n).

[0050] In step S6, the control device 50 sets the time when the passenger sensor 52 no longer detects the passenger J1 as time t0, and starts timing using the timer, and then proceeds to step S7.

[0051] In step S7, Figure 4As shown in (d), the control device 50 shortens the length of the prohibited area K at the rated speed V, and lengthens the safety area A located behind the prohibited area K. Then, the process proceeds to step S8.

[0052] In step S8, Figure 5 As shown in (a), when the camera 64 detects that the queue-jumping passenger J2 has entered the prohibited area K from the start of the timer (t0) to the interval ensuring time T, the process proceeds to step S10 (case y); if no detection is made, the process proceeds to step S9 (case n).

[0053] In step S9, if Figure 4 As shown in (e), when there are no other passengers on board and the timer ends the timing of the interval ensuring time T, the control device 50 ends the display of the prohibited area K and returns to step S2 (case y); when the timer does not end the timing of the interval ensuring time T, it returns to step S7 (case n).

[0054] On the other hand, in step S10, the control device 50 uses the speaker 54 to warn the passenger J2 who cuts in line in the prohibited area K before the interval ensuring time T has passed, so that the passenger J2 can keep an appropriate interval with the passenger J1 who got on first. Then, the control device returns to step S4.

[0055] (5) Effect

[0056] According to the present embodiment, when a passenger has boarded the steps 30, a prohibited area K where the next passenger is prohibited from boarding is displayed on the boarding and landing plate 32, so that the passenger and the next passenger can have an appropriate interval. Then, the passenger moves at the rated speed V together with the steps 30, and the length of the prohibited area K is also shortened. Thus, the boarding of passengers can be suppressed, and an appropriate interval d between passengers can be ensured.

[0057] Furthermore, when other passengers enter the prohibited area K, it is possible to issue a warning to the other passengers.

[0058] Furthermore, in the case where other passengers do not follow the instructions of the voice and get on the step 30 from the prohibited area K, the prohibited area K with the interval length L is displayed again, and its length is shortened in accordance with the rated speed V of the escalator 10. Therefore, in the case where there are passengers following the queue-jumping passenger, the distance between the queue-jumping passenger and the following passenger can be ensured to be an appropriate interval d.

[0059] (6) Example of changes

[0060] In the above embodiment, a plurality of LEDs 66 and 70 are arranged in a grid pattern on the entire upper surface of the boarding and landing boards 32 and 34 to display the safety area A and the prohibited area K. However, instead, an image display device such as a liquid crystal display device may be arranged on the upper surface of the boarding and landing boards 32 and 34 to display the green safety area A and the red prohibited area K. In particular, when a liquid crystal display device is used, not only the red and green colors can be displayed, but also "no entry here" and the like can be displayed through animation. In addition, a projector may be arranged on the ceiling surface 4 on the boarding and landing boards 32 and 34, and the boarding and landing boards 32 and 34 may be projected and mapped using the projector to display the safety area A and the prohibited area K.

[0061] In addition, in the above-mentioned embodiment, the safety area A and the prohibited area K are provided in a strip shape in the middle of the left-right direction of the boarding and landing boards 32 and 34, but the present invention is not limited thereto, and the LEDs 66 and 70 may be provided only on the left and right sides of the boarding and landing boards 32 and 34, and the safety area A and the prohibited area K may be displayed on the left and right ends of the boarding and landing boards 32 and 34. Furthermore, guide frames may be provided upright on the left and right sides of the boarding and landing boards 32 and 34, respectively, and LEDs 66 and 70 may be provided on the upper part of the guide frames to display the prohibited area K and the safety area A.

[0062] In addition, in the above-mentioned embodiment, the camera 64 provided on the ceiling surface 4 detects passengers on the boarding and landing plates 32 and 34, but the present invention is not limited thereto, and passengers riding on the steps 30 may be detected. Then, an image display device or a lighting device is provided on the pair of left and right handrails 36, 36 to guide passengers standing on the steps 30 to stand at an appropriate interval. Specifically, when there are passengers walking down the steps 30, this is detected by the camera 64, and a warning or instruction is given using the image display device or the lighting device provided on the handrail 36.

[0063] In the above-described embodiment, the boarding of a passenger is detected by the passenger sensors 52 and 56 constituted by photoelectric sensors, but the boarding of a passenger may be detected by the camera 64 located on the ceiling surface.

[0064] Furthermore, in the above-mentioned embodiment, the case where the embodiment is applied to the escalator 10 has been described, but the embodiment may be applied to a moving walkway instead.
