In addition, the control device 50 can perform image analysis on passengers based on the dynamic images (or still images) captured by the camera 64 .

(3) Description of the operation of the entry suppression device 5

The getting-on suppression device 5 of the present embodiment is used to suppress the getting-on of passengers, and operates to secure an appropriate distance d between passengers as shown in FIG. 1 . For example, as shown in FIG. 1 , when the step 30 descends, a camera 64 , an LED 66 arranged on the landing board 32 on the upper side, an LED lighting circuit 68 , a passenger sensor 52 , and a speaker 54 are used to suppress the entry of passengers.

More specifically, as shown in (a) of Figure 4, under the state that no one rides into the escalator 10, the control device 50 uses the LED lighting circuit 68 to display from the comb-tooth plate 60, that is, the boarding and descending board 32, with LED66. The boundary between the front end of the step 30 and the step 30 (hereinafter simply referred to as "boundary") is toward the rear of the upper surface of the boarding 32 along the front-to-back direction of the strip-shaped safety zone A. This safety area A is an area showing a range in which passengers can board, with all the plurality of LEDs 66 arranged in a grid pattern lit green. The control device 50 also always performs image analysis on the dynamic images captured by the camera 64 to detect whether passengers get on the landing board 32 or not. In addition, in FIGS. 4 and 5 , the range indicated by dots on the landing board 32 is the safety area A. As shown in FIG.

Next, as shown in FIG. 4( b ), when a passenger J1 walks into the safe area A on the upper surface of the landing board 32 and comes to the comb plate 60 (boundary), the passenger sensor 52 detects it. Then, the control device 50 uses the LED 66 to display in red the prohibited area K having the interval length L (for example, about 1 m) to ensure a predetermined interval between passengers on the landing board 32 from the comb plate 60 (boundary) to the rear. In addition, in FIGS. 4 and 5 , the hatched area of the landing board 32 is the prohibited area K. As shown in FIG. The prohibited area K is a space required to obtain an appropriate interval d from the passenger J1 who intends to board the step 30 to the rear of the space length L, and is an area indicating that other passengers are prohibited from entering, and for easy understanding, it is Area K is prohibited and displayed in red. In addition, the control device 50 provides guidance with a voice "Please do not enter the red prohibited area" from the speaker 54 on the upper floor as needed.

Next, as shown in FIG. 4(c) and FIG. 4(d), when the passenger J1 rides on the step 30, the step 30 moves downward at a predetermined speed (for example, a rated speed V of 30 m/min). On the other hand, when the passenger J1 has completely moved from the boarding 32 to the steps 30 , the passenger sensor 52 no longer detects the passenger J1 , so the timer inside the control device 50 starts timing from this time t0 . In addition, when the step 30 on which the passenger J1 rides moves downward at a rated speed V, the control device 50 acquires the information of the rated speed V from the drive circuit 51, and shortens the upper surface of the landing board 32 according to the rated speed V. The length in the front-back direction of the forbidden area K extending in a strip shape. Thereby, the rear end part of the prohibition area|region 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-back direction on the upper surface of the landing board 32 by the amount in which the length of the prohibited area K in the front-back direction is shortened.

Next, as shown in (e) of FIG. 4 , the timer starts counting from time t0, and when the interval ensuring time T has elapsed, the control device 50 ends the display of the prohibited area K, and sets the entire upper surface of the landing board 32 as a safe area. A display. As shown in FIG. 1 , this "interval guarantee time T" is the time for making the distance between passengers on the steps 30 an appropriate interval d, and when the appropriate interval d is set to 2 m, for example, and the rated distance of the escalator 10 When the velocity V is set to 30 m/min (=0.5 m/sec), the gap securing time T=d/V=2/0.5=4 (sec). Therefore, the control device 50 shortens the forbidden region K from the interval length L, and ends the display at T=4 seconds. In addition, as the speed v of shortening the prohibition 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 portion of the forbidden area K reaches the comb plate 60 (boundary), the display of the forbidden area K ends.

However, as shown in (a) of FIG. 5 , the control device 50 sometimes detects from the moving image of the camera 64 that one passenger J1 enters the step 30 and another passenger J2 enters the prohibited area K until the interval ensuring time T elapses. Condition. Hereinafter, the other passenger J2 is referred to as "queue jumping passenger J2".

At this time, as shown in FIG. 5( b ), the control device 50 displays the prohibition area K of the interval length L again backward from the comb plate 60 (boundary). Then, the speaker 54 is used to warn the passenger J2 who jumps in line to the prohibited area K with the sound "entry is prohibited in the red prohibited area". When the queue jumping passenger J2 comes out of the prohibited area K according to the voice instruction, the queue jumping passenger J2 will not approach the passenger J1.

But, as shown in (c) of Fig. 5, (d) of Fig. 5, and (e) of Fig. 5, when the jumping passenger J2 does not follow the instruction of the voice and gets on the step 30 from the prohibited area K, Passenger sensor 52 detects the passenger J2 who jumps in line once, after that, from the time t0 when it is not detected, the control device 50 starts the timing of the timer, and from this time t0, the length of the forbidden area K is corresponding to the rated speed V of the escalator 10 shortened. In this way, when there is a passenger following the passenger who jumps in line J2, the distance between the passenger who jumped in line J2 and the following passenger can be kept at an appropriate interval d.

In addition, even if other passengers get on the safe area A of the landing board 32, the control device 50 does not change the display of the prohibited area K or the safe area A, but directly displays it. In addition, only when another passenger enters the prohibited area K, the above-mentioned control is performed assuming that the passenger J2 jumps in line.

In addition, the case when the step 30 descends was exemplified above, but when the step 30 ascends, the boarding suppression device 5 uses the camera 64, the LED 70 arranged on the boarding board 34 on the lower side, the LED lighting circuit 72, and the passenger sensor 56. , The loudspeaker 58 suppresses the entry of passengers.

(4) Operation sequence of the ride-in suppression device 5

Next, the operation procedure of the ride-on suppression device 5 will be described with reference to the flowchart of FIG. 3 .

In step S1, the descending operation of the escalator 10 is started. Step 30 descends at nominal speed V. In addition, at the same time, the passenger sensor 52 on the upper floor is activated, and the camera 64 positioned on the ceiling surface 4 detects passengers present on the landing board 32 on the upper floor. Then go to step S2.

In step S2, as shown in (a) of FIG. 4 , since there are no passengers on the boarder 32 on the upper floor, the control device 50 displays a green safety area A on the entire boarder 32 . Then go to step S3.

In step S3, as shown in (b) of Fig. 4, passenger J1 walks to the comb tooth plate 60 that is positioned at the front end portion of landing board 32, if passenger sensor 52 detects passenger J1, then enters step S4 (the situation of y) , in the case that the passenger J1 is not detected, the operation of step S3 is continued (in the case of n).

In step S4, as shown in (b) of FIG. A safe area A is displayed behind the rear end of the . Then go to step S5.

In step S5, as shown in (c) of Fig. 4, when passenger J1 rides into step 30 fully from boarding board 32, passenger sensor 52 enters step S6 (the situation of y) when passenger J1 no longer detects, also detects Continue to step S5 (case of n) when passenger J1 is reached.

In step S6, the control device 50 sets the time when the passenger J1 is no longer detected by the passenger sensor 52 as the time t0, and starts counting the time by the timer. Then go to step S7.

In step S7, as shown in (d) of FIG. 4 , the control device 50 shortens the length of the prohibited area K at the rated speed V, and lengthens the safe area A located behind the prohibited area K. Then go to step S8.

In step S8, as shown in (a) of FIG. S10 (the case of y), if not detected, go to step S9 (the case of n).

In step S9, as shown in (e) of FIG. ), and return to step S7 (in the case of n) when the timer has not finished counting the interval ensuring time T.

On the other hand, in step S10, the control device 50 uses the speaker 54 to call attention to the passenger J2 who jumps into the prohibited area K before the interval ensuring time T elapses, so that he can properly obtain a distance from the passenger J1 who boarded earlier. . Then return to step S4.

(5) Effect

According to this embodiment, when a passenger rides on the step 30, the prohibition area K which prohibits the next passenger from getting on is displayed on the landing board 32, so that the said passenger and the next passenger may take an appropriate distance. The passenger then moves with the step 30 at the nominal speed V, while also shortening the length of the exclusion zone K. Thereby, it is possible to suppress the entry of passengers and ensure an appropriate distance d between passengers.

In addition, when other passengers have entered the prohibited area K, it is possible to issue a warning to the other passengers.

Furthermore, when other passengers do not follow the instructions of the voice and ride on the step 30 from the prohibited area K, the prohibited area K with the interval length L is displayed again, and the length thereof changes in accordance with the rated speed V of the escalator 10. Therefore, when there is a passenger following the passenger who jumped in line, the distance between the passenger who jumped in line and the passenger who followed can be ensured to be an appropriate interval d.
