[0008] A passenger conveyor danger warning device 60 according to one embodiment of the present invention will be described with reference to Figures 1 to 12. In this embodiment, an escalator 10, which is one of the passenger conveyors, will be used for the description. When describing the front and rear directions of the escalator 10, the view is taken looking down from the upper floor (e.g., the 2nd floor) to the lower floor (e.g., the 1st floor), with the upper floor side being the rear and the lower floor side being the front.

[0009] In this specification, "luggage B" of passenger A means a carry-on bag, wheeled bag, suitcase, musical instrument, or other items that can be carried by hand. "Cart C" means a shopping cart provided in a supermarket and used by a person pushing it, a stroller, a pushcart owned by an elderly person, a wheelchair, etc.

[0010] (1) Escalator 10 The overall structure of the escalator 10 will be explained with reference to Figure 1. Figure 1 is a simplified diagram of the escalator 10 viewed from the right side in a vertical cross-section, with the right-side members omitted.

[0011] As shown in Figure 1, the truss 12, which is the framework of the escalator 10, is supported along the front-to-back direction using support angles 2 and 3, spanning the upper and lower floors of the building 1. The truss 12 is inclined in the portion that spans the upper and lower floors, with a horizontal section from where the inclined portion reaches the upper floor to the end, and a horizontal section from where the inclined portion reaches the lower floor to the end of the lower floor. The machine room 36 located inside the horizontal portion of the upper floor of the truss 12 houses the control unit 32 and drive unit 38 of the escalator 10. The control unit 32 also incorporates a judgment unit 34.

[0012] A pair of left and right balustrades 20, 20 made of transparent glass or acrylic are erected in the front-rear direction on both the left and right sides of the upper portion of the truss 12. The upper floor end 21 of this balustrade 20 is formed in a semicircular shape when viewed from the side, and the lower floor end 21 is also formed in a semicircular shape when viewed from the side.

[0013] A plurality of steps 14 connected in an endless manner are arranged between the lower portions of the pair of left and right balustrades 20, 20, and are raised or lowered by a motor 39 of a driving device 38.

[0014] Handrail rails 24, 24 are provided along the upper portions of the pair of left and right balustrades 20, 20 and the outer peripheral portions of the semicircular ends 21, 21. An endless handrail belt 22 is movably attached to the handrail rail 24, and the handrail belt 22 moves in synchronization with the steps 14. A skirt guard 30 is provided at the lower side portion of the balustrade 20, and the step 14 travels between the pair of left and right skirt guards 30, 30. An upper floor front skirt guard 31 is provided at the lower front portion of the semicircular end 21 of the upper floor balustrade 20, and a lower floor front skirt guard 31 is also provided at the lower front portion of the semicircular end 21 of the lower floor balustrade 20. An inlet portion 40, which is the entrance and exit of the handrail belt 22, protrudes from the front skirt guard 31.

[0015] Speakers 42 are provided on the skirt guard 30 near the upper floor landing and the skirt guard 30 near the lower floor landing. A lighting device 44 is provided on the handrail rail 24. This lighting device 44 will be described later.

[0016] At the upper floor landing, a landing plate 16 is horizontally placed on the horizontal portion of the truss 12, that is, on the machine room 36. At the lower floor landing, a landing plate 18 is horizontally placed on the horizontal portion of the truss 12. A comb-shaped yellow comb 26 is provided at the front end of the upper floor landing plate 16, and the steps 14 enter into and exit from this comb 26. A comb-shaped yellow comb 28 is also provided at the rear end of the lower floor landing plate 18.

[0017] (2) Dangerous boarding warning device 60 The dangerous boarding warning device 60 will be explained with reference to the block diagram in Figure 3. The dangerous boarding warning device 60 has a control unit 32 and a judgment unit 34, which also serve as the control device for the escalator 10.

[0018] (2-1) Control Unit 32 The control unit 32 is connected to a motor 39, a safety device 48, a communication device 50, a lighting device 44, and a speaker 42 via a drive circuit 46.

[0019] The drive circuit 46 controls the operation, stopping, rotation direction, and rotation speed of the motor 39 based on control signals from the control unit 32.

[0020] The safety devices 48 are devices that ensure the safety of passenger A, and include a skirt guard pinching detection device provided on the skirt guard 30, an inlet pinching detection device provided on the inlet sections 40, 40, and a step lifting detection device.

[0021] The lighting device 44 illuminates a pair of left and right railings 20, 20 made of transparent glass or acrylic, and consists of a tape LED with multiple LEDs, which are light sources, attached at predetermined intervals to a tape-shaped substrate. This lighting device 44 is attached from the end of the handrail rail 40 in the inlet section 40 of the upper floor to the inner circumference of the handrail rail 40 at the semicircular end 21 of the upper floor, and is also attached to the lower part of the handrail rail 40 that extends from the upper floor to the lower floor, and further extends through the inner circumference of the handrail rail 40 at the semicircular end 21 of the lower floor to the end of the handrail rail 40 in the inlet section 40 of the lower floor. The control unit 32 can individually control the lighting, blinking, and color of each LED. For example, the LED of the lighting device 44 in the inlet section 40 of the upper floor is designated as number 1, and the numbers are assigned sequentially, with the last LED in the inlet section 40 of the lower floor being designated as number n. The control unit 32 can then light up the 20th to 30th LEDs in white and make the other LEDs blink red. In the drawing, the area where the lighting device 44 is lit in white (normal lighting state) is shown as blank, and the area where it is blinking red is shown with hatching.

[0022] The communication device 50 can communicate with an external management server and a monitoring center for the escalator 10.

[0023] (2-2) Judgment section 34 The determination unit 34 is connected to the camera 5, pattern storage unit 52, priority storage unit 54, and history storage unit 58, and is also connected to the control unit 32.

[0024] Camera 5 is mounted on the ceiling 4 of building 1 and can capture images (moving and still images) of the entire escalator 10, from the upper boarding / alighting platform 16 to the lower boarding / alighting platform 18. It can capture images (moving and still images) of the actions of passenger A riding the escalator 10, people near the boarding / alighting areas, or people who intend to use the escalator 10.

[0025] The decision unit 34 analyzes the images sent from the camera 5 to determine which behavioral pattern passenger A currently on board corresponds to, as well as passenger A's location and the priority of that behavioral pattern.

[0026] "Behavioral patterns" refer to the movements and posture of passenger A, the presence and shape of luggage B and its positional relationship to passenger A, and the presence and shape of cart C and its positional relationship to passenger A. These patterns are derived by extracting a series of actions of one passenger A from the aforementioned images and analyzing these extracted actions. There are normal behavioral patterns and dangerous behavioral patterns.

[0027] A "normal behavior pattern" is, for example, the behavior of passenger A who is standing still on the steps 14 of an escalator 10, holding onto the handrail belt 22, and remaining stationary. It also includes the behavior of passenger A holding luggage B in their hands if they are carrying luggage B.

[0028] There are several "dangerous behavior patterns." For example, the first dangerous behavior pattern is the behavior of passenger A leaning over the railing 20 while riding; the second dangerous behavior pattern is the behavior of passenger A placing cart C onto the steps 14 and riding; the third dangerous behavior pattern is the behavior of passenger A placing luggage B on the steps 14 and riding hands-free; the fourth dangerous behavior pattern is the behavior of passenger A walking (including going against the flow) on the steps 14; the fifth dangerous behavior pattern is the behavior of passenger A running on the steps 14; and the sixth dangerous behavior pattern is the behavior of people standing and loitering on the upper boarding / alighting platform 16 or the lower boarding / alighting platform 18. However, in the case of loitering, this includes not only passenger A but also people near the boarding / alighting area and people who intend to use the escalator 10.

[0029] The pattern memory unit 52 stores images of passenger A's normal behavior patterns and images of dangerous behavior patterns. The decision unit 34 then compares the behavior patterns of passenger A, who is currently on board and captured and analyzed by camera 5, with the behavior patterns stored in the pattern memory unit 52 using pattern recognition to determine which behavior pattern applies. Alternatively, the decision unit 34 may pre-train and store dangerous behavior patterns in the pattern memory unit 52 using artificial intelligence (AI), and then estimate whether passenger A's behavior pattern is dangerous or not based on this. Once the decision unit has determined which behavior pattern applies, it assigns a corresponding label. For example, if the acquired behavior pattern is leaning out, it is labeled as "leaning out".

[0030] In addition to determining the behavioral patterns of passenger A as described above, the judgment unit 34 also determines the position of passenger A on the escalator 10 from the image captured by camera 5. This is because the position of passenger A is constantly changing as the steps 14 are moving up or down, so it is necessary to determine the position of passenger A exhibiting that behavioral pattern and transmit it to the control unit 32. This position is determined by comparing the background image of the current image showing passenger A with a background image not showing passenger A. For example, the position of a pillar in a background image not showing passenger A is pre-calculated and stored at what height on the escalator 10 it is located, and passenger A's position is determined from the position of the pillar in the background image of the image of passenger A currently on the escalator. This position of passenger A is used by the control unit 32 as LED position information to change the lighting position and lighting state of the LEDs (light sources) of the lighting device 44. Based on passenger A's position, the control unit 32 may, for example, light up the 20th to 30th LEDs in white and blink the other LEDs in red.

[0031] The priority memory unit 54 stores the priority corresponding to the labeled dangerous behavior patterns. "Priority" refers to the ranking (priority) of dangerous behavior patterns when multiple passengers A on the escalator 10 are simultaneously performing those dangerous behavior patterns. The judgment unit 34 then informs the control unit 32 to issue a warning to passenger A performing the most dangerous behavior pattern with priority 1.

[0032] For example, in the case of upward operation, priority 1 is the behavior pattern of passenger A leaning out from railing 20, priority 2 is the behavior pattern of passenger A placing cart C onto step 14, priority 3 is the behavior pattern of passenger A riding with luggage B without holding on, priority 4 is the behavior pattern of people loitering at the entrance / exit, priority 5 is the behavior pattern of passenger A while the train is moving, priority 6 is the behavior pattern of passenger A walking, and priority 7 is the behavior pattern of passenger A who is standing still but has let go of the handrail belt 22.

[0033] On the other hand, during descent, priority 1 is the behavior pattern of passenger A who is using cart C, priority 2 is the behavior pattern of passenger A who is riding with luggage B such as a carry-on bag without holding it, and priority 3 is the behavior pattern of passenger A leaning out from railing 20. The reason why the priority of passenger A's behavior pattern differs between ascending and descending is that during ascending, passenger A is at risk of being trapped between the handrail belt and the floor of the second floor and suffering serious injury, but this risk is lower during descending.

[0034] The history memory unit 58 stores the label of the dangerous behavior pattern of passenger A determined by the judgment unit 34, along with its priority and the time when the behavior occurred.

[0035] (3) Specific examples of warnings The control unit 32 makes a warning announcement from the speaker 42 and changes the illumination status of each LED in the lighting device 44 based on the behavior pattern of dangerous passenger A, its priority, and passenger A's boarding position, which are sent from the judgment unit 34. A specific example will be explained below.

[0036] First, if all passengers A are standing still on the steps 14 and holding onto the handrail belts 22, that is, if all passengers A are behaving normally, the lighting devices 44 covering the entire range of the pair of railings 20, 20 will be illuminated in white, and no warning will be issued.

[0037] As shown in Figure 1, when passenger A is running or walking on the steps 14 during descent, in order to prevent passenger A from falling or colliding with other passengers A during a sudden stop, all of the lighting devices 44 in the lower range will flash red and the upper range will be illuminated white, depending on passenger A's position. In addition, a warning announcement, "Please do not walk or run," will be made from speaker 42. The same applies during ascent.

[0038] As shown in Figure 5, in the case of passenger A's behavior pattern during ascending operation, where passenger A is holding luggage B without holding it, all lighting devices 44 below passenger A's position will flash red to warn people below passenger A of the danger, in order to prevent luggage B from falling and involving other passengers A. The lighting devices 44 above passenger A will remain lit in normal white. In addition, a warning announcement will be made from speaker 42 saying, "Do not let go of luggage B."

[0039] As shown in Figure 6, in the case of passenger A's behavior pattern during descent where luggage B is released from the passenger, all lighting devices 44 below passenger A will flash red to prevent luggage B from falling and involving other passengers A, while the lighting devices 44 above passenger A will remain lit in normal white. In addition, a warning announcement, "Please do not let go of luggage B," will be made from speaker 42.

[0040] As shown in Figure 7, in the case of passenger A's behavior pattern when the train is ascending and has placed cart C on the steps 14, all lighting devices 44 below the position of cart C are set to flash red, and all lighting devices 44 above it are set to flash white, in order to prevent cart C from falling and involving other passengers A. Since the train is ascending, the range of lighting devices 44 that flash red widens each time cart C rises. In addition, a warning announcement is made from speaker 42: "Do not let go of cart C. Please be careful as cart C is on board."

[0041] As shown in Figure 8, in the case of passenger A's behavior pattern when the train is descending and has placed cart C on the steps 14, all lighting devices 44 below the position of cart C are set to flash red, and all lighting devices 44 above it are set to light up white, in order to prevent cart C from falling and involving other passengers A. As the train is descending, the range of lighting devices 44 that flash red narrows each time cart C descends. In addition, a warning announcement is made from speaker 42: "Do not let go of cart C. Please be careful as cart C is on the platform."

[0042] As shown in Figure 9, during upward operation, if passenger A is leaning over the railing 20 while boarding the steps 14, the lighting device 44 near passenger A will flash red and the rest of the area will be illuminated white to prevent passenger A from being trapped between the second floor and the railing 20. In addition, a warning announcement will be made from speaker 42 stating, "Leaning over the railing is extremely dangerous. Please return to your original position." In Figure 9, a board 56 is suspended between the second floor and the railing 20 to warn passenger A of the danger.

[0043] As shown in Figure 10, during descent, if passenger A is leaning over the railing 20, the lighting device 44 near passenger A will flash red and the rest of the area will be illuminated white to prevent passenger A from falling. In addition, a warning announcement will be made from speaker 42 stating, "Leaning over the railing is extremely dangerous. Please return to your original position." In Figure 10, a board 56 is suspended between the second floor and the railing 20 to warn passenger A of the danger.

[0044] As shown in Figure 11, if a person is standing and lingering on the upper floor boarding / alighting platform 16 during upward operation, the semicircular lighting device 44 at the semicircular end 21 of the upper floor will flash red, and the rest of the area will be illuminated white, in order to prevent a collision with other passengers A coming down from the escalator 10. In addition, a warning announcement will be made from speaker 42 stating, "Passenger A is coming up. Please move immediately."

[0045] As shown in Figure 12, if there is a person standing on the lower platform 18, the semicircular lighting device 44 at the semicircular end 21 of the lower platform will flash red, and the rest of the area will be illuminated white, in order to prevent a collision with other passengers A coming down from the escalator 10. In addition, a warning announcement will be made from speaker 42 saying, "Passenger A is coming down. Please move immediately."

[0046] Although not illustrated, if passenger A is standing still on step 14 but is holding a smartphone and therefore not gripping the handrail belt 22, the lighting device 44 at passenger A's position will flash red and the rest of the area will be illuminated white to prevent passenger A from falling during a sudden stop. Additionally, a warning announcement will be made from speaker 42 saying, "Please hold onto the handrail."

[0047] (4) Operating status of the dangerous boarding warning system 60 Next, the operating status of the dangerous boarding warning device 60 will be explained with reference to the flowchart in Figure 4.

[0048] In step S1, the operation of the escalator 10 is started. For example, upward operation is started. Then the process proceeds to step S2.

[0049] In step S2, if passenger A is on escalator 10, the images from camera 5 are analyzed to obtain the behavioral patterns of each passenger A, and the process proceeds to step S3.

[0050] In step S3, the behavioral patterns stored in the pattern memory unit 52 are compared with the acquired behavioral patterns of the current passenger A, and the process proceeds to step S4.

[0051] In step S4, determine whether passenger A's behavior pattern is normal or dangerous. If it is normal, return to step S2 (if n). If it is dangerous, proceed to step S5 (if y).

[0052] In step S5, the boarding position of passenger A, who exhibits a dangerous behavioral pattern, is detected, and the process proceeds to step S6.

[0053] In step S6, the acquired dangerous behavior patterns are labeled and classified into priority levels corresponding to those patterns, and the process proceeds to step S7. For example, if the acquired behavior pattern is leaning over, it is labeled as leaning over, and because it is an upward operation, its priority is classified as 1.

[0054] In step S7, the label of the acquired current dangerous behavior pattern, its priority, and the time it occurred are stored in the history storage unit 58. Then the process proceeds to step S8.

[0055] If multiple passengers A are identified in step S8 as exhibiting a dangerous behavioral pattern, the process proceeds to step S9; otherwise, the process proceeds to step S11.

[0056] In step S9, the multiple passengers A exhibiting dangerous behavioral patterns are ranked in order of priority, and the process proceeds to step S10.

[0057] In step S10, select the highest priority (most dangerous) behavioral pattern and proceed to step S11. For example, if there is a passenger A leaning out and another passenger A walking during an upward movement, select the behavioral pattern of passenger A leaning out, which has higher priority. Then proceed to step S11.

[0058] In step S11, as explained in the specific example above, the lighting device 44 is made to flash red in the location and range corresponding to the dangerous behavior pattern. Then proceed to step S12.

[0059] In step S12, a warning announcement is made from speaker 42. Then the process proceeds to step S13.

[0060] In step S13, it is determined from the image acquired by camera 5 whether or not passenger A is continuing the dangerous behavior. If not, the process proceeds to step S17 (if n), and if continuing, the process proceeds to step S14 (if y).

[0061] In step S14, if the accident risk for passenger A is high, the process proceeds to step S15 (if y), and if the accident risk is low, the process proceeds to step S16 (if n). For example, if passenger A is leaning over the railing 20 during an upward movement, the accident risk is judged to be very high, while if passenger A is walking, the accident risk is judged to be low. Specifically, the decision is made based on priority, with priority levels 1-4 indicating a high accident risk and priority levels 5-7 indicating a low accident risk.

[0062] In step S15, to avoid an accident involving passenger A, who exhibits a dangerous behavioral pattern, the operating speed of the steps 14 of the escalator 10 is reduced or stopped. Then the process proceeds to step S16.

[0063] In step S16, a warning announcement is made because the dangerous behavior continues, and the process returns to step S2.

[0064] In step S17, since the dangerous behavior has been stopped, the LED color of the lighting device 44 is changed back to white and the process proceeds to step S18.

[0065] In step S18, an announcement of thanks is made and the process returns to step S2. For example, an announcement of thanks is made to passenger A, who was leaning out, for stopping the leaning.

[0066] (5) Effects According to this embodiment, if the actions of passenger A on the escalator 10 are dangerous, the LEDs of the lighting device 44 can be changed to a different color from the normal color and made to flash accordingly, clearly indicating the danger to passenger A. At the same time, a warning announcement is made from the speaker 42, making it possible to more reliably convey the danger.

[0067] Furthermore, the judgment unit 34 makes a judgment on dangerous behavior patterns by comparing them with dangerous behavior patterns that have been stored in advance, thus ensuring reliable judgment. In particular, the position and range in which the lighting device 44 is flashed are determined based on the position of passenger A, so that passenger A can be identified as being in danger at a glance.

[0068] Furthermore, if passenger A is boarding with luggage B unattended, the lighting device 44 at passenger A's boarding position and below it will flash red, thus warning not only passenger A who is engaging in this dangerous behavior, but also other passengers A below them.

[0069] Furthermore, if passenger A is boarding with cart C on step 14, the lighting device 44 below passenger A's boarding position will also flash red, thus warning not only passenger A but also other passengers A below.

[0070] Furthermore, in the case of passenger A leaning over the railing 20, the lighting device 44 will flash red only on that part of the railing 20, thereby clearly communicating to passenger A that there is danger.

[0071] Furthermore, the lighting device 44 at the semicircular end 21 flashes red to alert passengers A who are loitering on the upper or lower boarding / alighting platforms 16 and 18, respectively, thereby ensuring that these loitering passengers A are reliably warned.

[0072] (6) Example of changes In the above embodiment, the lighting device 44 flashes white in normal conditions and red in dangerous conditions. However, it may instead be illuminated red in dangerous conditions, or its color may change to yellow, red, etc., depending on the degree of danger. Furthermore, the flashing interval may be shortened as the degree of danger increases.

[0073] Furthermore, although the above embodiment was described using an escalator 10, this embodiment is not limited to this and can also be applied to, for example, a moving walkway having an inclined section.

[0074] Furthermore, in the above embodiment, both lighting devices 44 of the pair of left and right railings 20, 20 were flashed red, but this is not limited to this, and only the lighting device 44 of one of the left or right railings 20 may be flashed red. For example, for a passenger A leaning out of a railing 20, only the lighting device 44 of the railing 20 on the side from which the passenger is leaning out may be flashed red.

[0075] Furthermore, although the above embodiment had one imaging unit, alternatively, the camera 5 may have two imaging units spaced a predetermined distance apart, acquire stereo images from these units, and analyze these stereo images to extract the boarding position of passenger A in the image, including the depth direction of the three-dimensional region, thereby identifying the boarding position of passenger A on the escalator 10.

[0076] Furthermore, although the determination unit 34 is located inside the control unit 32 in the above embodiment, the determination unit 34 is not limited to this configuration and may be located on a management server outside the escalator 10, with data being transmitted and received via the communication device 50.

[0077] Furthermore, in the above embodiment, the determination unit 34 determined passenger A's behavior pattern and boarding position from the image from camera 5. However, a sensor (for example, a distance sensor) may also be added to camera 5, and passenger A's behavior pattern and boarding position may be determined from this information.

[0078] Furthermore, although one embodiment of the invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and essence of the invention, as well as in the claims of the invention and its equivalents. [Explanation of Symbols]
