[0003] Conventionally, maintenance of a passenger conveyor such as an escalator or a moving walk is performed by a specialized technician, but the work is usually performed by a plurality of people in consideration of safety and the like, and the work time requires a large amount of time. Therefore, in order not to consume human resources, it is also considered to perform maintenance of the passenger conveyor by a robot. For example, the robot rides on a step of the passenger conveyor, and checks whether or not the passenger conveyor has an abnormality while moving the step.

[0004] However, when an abnormality is found by the maintenance by the robot described above, in order to determine the position where the abnormality exists, it is necessary to determine the absolute position of the robot, that is, which position of the passenger conveyor is abnormal, but in order to determine the position of the robot, it is necessary to provide a GPS system in a building where the passenger conveyor is installed, a system that analyzes the position of the robot by a camera installed on the ceiling of the building, and there is a problem that a large-scale device is required to only grasp the absolute position of the robot. SUMMARY

[0005] Therefore, an embodiment of the present application is made in view of the above-described problem, and an object thereof is to provide a passenger conveyor system, a passenger conveyor, and a mobile body used for the passenger conveyor, which can simply determine which position the mobile body is with respect to the passenger conveyor when the mobile body rides on a step of the passenger conveyor and moves.

[0007] Further, the mobile body of the embodiment of the present application is characterized by having a marker detection section provided to the passenger conveyor, detecting an identifier of a marker provided to each of the passenger conveyors from a plurality of markers including the identifier for specifying the position of each of the passenger conveyors, a phenomenon detection section detecting a specific phenomenon during movement of a step of the passenger conveyor in the front-rear direction, and a mobile body control section storing the identifier of the marker detected by the marker detection section when the phenomenon detection section detects the phenomenon.

[0008] The passenger conveyor of the embodiment of the present application is characterized by having a step moving in a front-rear direction from one landing to another landing, and a plurality of markers provided to the passenger conveyor including an identifier for specifying the position of each of the passenger conveyors.

[0016] (First Embodiment)

[0017] In the first embodiment, reference will be made to Figures 1-5 The passenger conveyor system, that is, the escalator 10 and the mobile body 100 will be described.

[0018] (1) Escalator 10

[0019] Reference will be made to Figure 1 The overall configuration of the escalator 10 will be described. Figure 1is an explanatory view of the escalator 10 as viewed from the left side. However, the illustration of the left side member of the escalator 10 is omitted in order to easily understand the internal configuration of the escalator 10. In addition, when the front-rear direction of the escalator 10 is explained, if viewed upward from the lower layer toward the upper layer, the upper layer is the front side and the lower layer is the rear side.

[0020] The truss 12, which is the frame of the escalator 10, spans the upper layer and the lower layer of the building 1, and is supported in the front-rear direction by the support angle irons 2, 3.

[0021] A drive device 18 that causes the steps 30 to travel, a left and right pair of step sprockets 24, 24, and a left and right pair of belt sprockets, not shown, are provided inside the machine room 14 on the upper layer side at the upper end portion of the truss 12. The drive device 18 has a motor 20, a speed reducer 21, a drive small sprocket 19 mounted to the output shaft of the speed reducer 21, and a disc-shaped electromagnetic brake 23 that stops the rotation of the motor 20 and maintains the stopped state. A drive large sprocket 17 is coaxially mounted on the left and right pair of step sprockets 24, 24, and a looped drive chain 22 is spanned between the drive large sprocket 17 and the drive small sprocket 19. Further, a control device 50 that controls the motor 20, the electromagnetic brake 23, and the like is provided inside the machine room 14 on the upper layer side.

[0022] A left and right pair of driven sprockets 26, 26 are provided inside the machine room 16 on the lower layer side at the lower end portion of the truss 12. A left and right pair of looped step chains 28, 28 are spanned between the left and right pair of step sprockets 24, 24 on the upper layer side and the left and right pair of driven sprockets 26, 26 on the lower layer side. Between the left and right pair of step chains 28, 28, a left and right pair of first wheels 301, 301 to which a plurality of steps 30 are coupled at a certain interval are provided. When the motor 20 rotates, the first wheels 301 of the steps 30 travel on a first wheel dedicated guide rail, not shown, fixed to the truss 12, and the second wheels 302 of the steps 30 travel on a second wheel dedicated guide rail 25 fixed to the truss 12.

[0023] A left and right pair of balustrades 36, 36 are provided upright on both left and right sides of the upper portion of the truss 12. A handrail rail 39 is provided at the upper portion of the balustrade 36, and a looped handrail belt 38 moves along the handrail rail 39.

[0024] A front skirt guard 40 on the upper layer side is provided at the lower portion of the front surface of the left and right pair of balustrades 36 on the upper layer side, and a front skirt guard 42 on the lower layer side is provided at the lower portion of the front surface on the lower layer side. Entrance portions 46, 48, which are entrances of the handrail belt 38, protrude from the front skirt guards 40, 42, respectively. Skirt guards (inner cover plates) 44 are provided at the lower portions of the side surfaces of the left and right pair of balustrades 36, respectively, and the steps 30 travel between the left and right pair of skirt guards 44, 44.

[0025] The handrail 38 moves in synchronization with the steps 30 by rotating with the step sprocket 24 through an unillustrated belt sprocket.

[0026] A landing plate 32 on the upper floor side is horizontally provided on the landing between the left and right skirt guards 44, 44 on the upper floor side and on the ceiling surface of the machine room 14. A landing plate 34 on the lower floor side is horizontally provided on the landing between the left and right skirt guards 44, 44 on the lower floor side and on the ceiling surface of the machine room 16. A comb plate 60 in the form of a comb is provided at the front end of the landing plate 32 on the upper floor side, and the steps 30 enter or are pulled out of the comb plate 60. Further, a comb plate 62 in the form of a comb is also provided at the front end of the landing plate 34 on the lower floor side.

[0027] (2) Mark 70

[0028] As shown in Figure 1 , marks 70 (70-1 to 70-9) are attached at regular intervals on the upper portion of the handrail (e.g., the left-hand side handrail) 36 of one of the left and right handrails 36, 36. The marks 70 are attached at positions on the upper portion of the handrail 36 and a number of positions below the handrail rail 39. Further, the marks 70 are attached at intervals of 20 cm from the landing on the lower floor to the landing on the upper floor. In Figure 1 , the number of marks 70 is assumed to be nine for the sake of easy understanding of the explanation.

[0029] The mark 70 on the lowermost floor is denoted as mark 70-1, and the marks 70 on the upper floor side are denoted by increasing the secondary number. The mark 70-1 is attached above the landing plate 34 on the lower floor, and the mark 70-9 is attached above the landing plate 32 on the upper floor. Further, the marks are denoted as "marks 70" when the marks are collectively explained, and are denoted as "mark 70-5", for example, when the individual marks are explained.

[0030] As shown in Figure 2As shown, the mark 70-5 is in the shape of a teardrop shape horizontally placed by a circular arc and a substantially triangular shape. In order to easily understand the up-down direction, the circular arc portion is disposed on the right side as the upper side, two sides of the substantially triangular shape are disposed on the left side as the lower side, and the tip portion of the triangular shape points to the lower side. Also, in the mark 70-5, "5 / 9" is written, the numerator "5" indicates the 5th mark 70 from the bottom, and the denominator "9" indicates the total number of marks 70. Since it is the 5th mark 70 from the bottom, it is known that it is attached to the handrail 36 in the upward direction from the lowermost mark 70-1 by 20 cm x 4 = 80 cm, and the position in the escalator 10 can be accurately determined. Also, the number "5" is an identifier that determines the position of the mark 70-5, and as long as the identifier is determined, the position from the lowermost mark 70-1 can be determined. For the other marks 70-1, 70-2 to 70-4, and 70-6 to 70-9, the number written in the numerator of the mark 70 is an identifier.

[0031] (3) Mobile body 100

[0032] Next, with reference to Figure 3 A mobile body 100 for performing maintenance of the escalator 10 will be described. The mobile body 100 is an autonomous traveling robot, and its purpose is to perform maintenance of the escalator 10 without a person.

[0033] The mobile body 100 has a substantially cubic main body 102, and the size of the main body 102 is designed to be able to ride on the size of the step 30. Inside the main body 102, a mobile body control section, that is, a robot control section 104, is provided, which is constituted by a computer or the like. In the lower portion of the main body 102, four wheels 106 are provided, and the four wheels 106 are rotated by a traveling motor 108. The robot control section 104 controls the rotation, stop, and rotation direction of the traveling motor 108, and thereby the mobile body 100 can advance, retreat, or rotate to the right or left.

[0034] In the main body 102, a camera 110 for photographing the outside of the mobile body 100 is provided. The robot control section 104 scans the mark 70 from a dynamic image (or a still image) photographed by the camera 110, and when the mark 70 can be image-recognized Figure 2In the case of the marker 70 shown, the further image recognition of the number (e.g., 5 / 9) indicated by the marker 70 recognizes "5" as the identifier n of the marker 70. Thus, the camera 110 functions as a marker detection section. The field of view of the camera 110 is preferably set to be able to capture one marker 70 as much as possible, but in the case where two or more markers 70 are reflected in the image, the markers 70 are individually subjected to image recognition, and the largest marker 70 is recognized as the marker 70 through which the mobile body 100 is passing. The reason for this is that the size of the recognized image is proportional to the distance from the mobile body 100.

[0035] A microphone 112 for taking in sound outside the mobile body 100 is provided in the main body 102. The robot control section 104 recognizes an abnormal sound in the case where the size of the sound taken in from the microphone 112 exceeds a predetermined sound size.

[0036] A vibration detection section 114 for detecting the vibration of the main body 102 itself is provided in the main body 102. The robot control section 104 recognizes an abnormal vibration in the case where the vibration value detected by the vibration detection section 114 exceeds a predetermined vibration value. Thus, the vibration detection section 114 functions as a phenomenon detection section.

[0037] The robot control section 104 stores in the storage section 116 the abnormal vibration phenomenon indicating the detection of an abnormal vibration, the abnormal sound phenomenon indicating the detection of an abnormal sound, and the detection time at which these phenomena were detected. In addition, the robot control section 104 has a robot communication section 118 for communicating with the outside of the mobile body 100.

[0038] (4) Electrical configuration of escalator 10 and mobile body 100

[0039] Next, the electrical configuration of the escalator 10 and the mobile body 100 will be described with reference to the block diagram of Fig. 2. Figure 4

[0040] The control device 50 inside the upper mechanical room 14 is connected to the robot communication section 118 of the mobile body 100, the communication section 64 for contacting the maintenance center outside, the drive circuit 66 for controlling the motor 20 and the electromagnetic brake 23, and the safety device 68 of the escalator 10.

[0041] ​The safety device 68 includes a skirt guard pinch detection device, an entrance pinch detection device, a step float detection device provided to the guide rail 25, an emergency stop button, and the like. The skirt guard pinch detection device is a device provided to the skirt guard 44, which detects a case where a foreign object (for example, clothes, baggage) is pinched between the skirt guard 44 and the step 30. The entrance pinch detection device is a device provided to the entrance portion 46, 48, which detects a case where a foreign object (for example, a passenger's hand, baggage) is pulled into the entrance portion 46 or the entrance portion 48 where the handrail belt 38 is pulled in, together with the handrail belt 38.

[0042] The robot control section 104 of the mobile body 100 is connected to a movement motor 108, a camera 110, a microphone 112, a vibration detection section 114, a storage section 116, and a robot communication section 118 that communicates with the communication section 64.

[0043] (5) Inspection based on the mobile body 100

[0044] Next, a case where the escalator 10 is inspected using the mobile body 100 will be described with reference to the flowchart of Figure 5 In this description, it is assumed that the steps 30 of the escalator 10 are ascending. First, the mobile body 100 is moved to the lower landing, that is, the landing plate 34. From this position, inspection is performed based on the mobile body 100.

[0045] In step S1, the robot control section 104 of the mobile body 100 transmits a movement stop signal to the communication section 64 of the escalator 10 using the robot communication section 118. Then, the control device 50 stops the motor 20, and the movement of the steps 30 is stopped. Then, the process proceeds to step S2.

[0046] In step S2, the robot control section 104 scans the marker 70-1 on the lowermost side of the escalator 10 using the dynamic image of the camera 110, and recognizes the identifier 1 of the marker 70-1. Thus, the mobile body 100 can recognize that it itself is present on the lower landing plate 34, and the process proceeds to step S3.

[0047] In step S3, the number of the identifier, that is, n, is initialized to 1. This is because the identifier 1 of the marker 70-1 was recognized in step S2. Then, the process proceeds to step S4.

[0048] In step S4, the robot control section 104 uses the camera 110 to identify whether the step 30 is stopped based on the safety boundary line displayed in yellow on the step face of the step 30, and if the step 30 is completely stopped, causes the moving motor 108 to drive to move the moving body 100 to the lowermost step 30 and stop thereon. Then, the process proceeds to step S5. Further, the reason for moving the moving body 100 after stopping the step 30 is to prevent the moving body 100 from falling down due to the movement of the step 30.

[0049] In step S5, the robot control section 104 instructs the control device 50 of the escalator 10 to raise the step 30 at the rated speed. Then, the process proceeds to step S6.

[0050] In step S6, since the step 30 is being raised, the robot control section 104 judges whether the vibration detection section 114 detects abnormal vibration of the step 30. Then, in the case where abnormal vibration is detected, the process proceeds to step S7 ("Yes" case), and in the case where abnormal vibration is not detected, the process proceeds to step S8 ("No" case).

[0051] In step S7, the robot control section 104 stores the identification number n of the marker 70 indicating the position where abnormal vibration is detected, the abnormal vibration phenomenon indicating that abnormal vibration has occurred, and the detection time into the storage section 116. Then, the process proceeds to step S8. Further, as the cause of the generation of abnormal vibration in the step 30, for example, the damage of the guide rail 25 through which the step 30 moves, the damage of the first wheel 301 and the second wheel 302, the absence, and the like can be considered.

[0052] In step S8, the moving body 100 is raised with the step 30 to the position where the marker 70 of the identifier n is attached, and the robot control section 104 judges whether abnormal sound is detected in the sound acquired by the microphone 112, and if detected, the process proceeds to step S9 ("Yes" case), and if not detected, the process proceeds to step S10 ("No" case).

[0053] In step S9, the robot control section 104 stores the identifier n of the marker 70 indicating the position where the abnormal sound is detected, the abnormal sound phenomenon indicating that abnormal sound has occurred, and the detection time into the storage section 116, and proceeds to step S10.

[0054] Since the step 30 is continuously raised, in step S10, the robot control section 104 judges whether the next identifier (n+1) of the identifier n of the marker 70 detected last time is recognized, and if recognized, the process proceeds to step S11, and if not recognized, the process returns to step S6.

[0055] In step Sll, the robot control section 104 recognizes the identifier (n+1) of the next marker 70, so the mobile body 100 ascends together with the step 30 at the position of the marker 70 of the identifier (n+1), and is set to n=n+1, and proceeds to step S12.

[0056] In step S12, in the case of the marker 70 of the identifier n=9, that is, in the case where the mobile body 100 reaches the upper floor by the ascent of the step 30, it proceeds to step S13 ("Yes" case), and in the case where it does not reach the upper floor, it returns to step S6 ("No" case), and continues the detection of the abnormal vibration and the abnormal sound at the position of the recognition number n+1 of the next marker 70.

[0057] In step S13, the robot control section 104, since it recognizes the marker 70-9 (identifier 9) that is on the uppermost floor, sets the mobile body 100 to reach the landing 32 on the upper floor side, stops the operation of the escalator 10, and proceeds to step S14.

[0058] In step S14, in the case where the abnormal vibration phenomenon or the abnormal sound phenomenon is stored in the storage section 116, it proceeds to step S15 ("Yes" case), and in the case where it is not stored, it ends ("No" case).

[0059] In step S15, the robot control section 104 notifies the maintenance center or the like where the technician is located, or the like, of the maintenance information that is a group of the category of the abnormal vibration phenomenon or the abnormal sound phenomenon, the recognition number n of the marker 70 at the time of generation of the abnormal phenomenon (that is, the position of generation of the abnormal phenomenon), and the detection time, via the robot communication section 118 and the communication section 64 of the control device 50, and ends. Thus, in the maintenance center, the maintenance of the escalator 10 can be performed unmanned without dispatching the technician.

[0060] (6) Effects

[0061] According to the present embodiment, the mobile body 100 can recognize its own position from the plurality of markers 70 provided to the rail 36 of the escalator 10, and in the case where an abnormal phenomenon that has a problem in the maintenance occurs, it can determine the position of generation of the abnormal phenomenon by the identifier of the marker 70. Therefore, it is not necessary to provide a large-scale device such as a building indoor GPS system, a system that analyzes the position of the mobile body 100 by a camera installed to the ceiling of the building, and the like.

[0062] (2nd Embodiment)

[0063] Next, the escalator 10 of the second embodiment will be described. In the first embodiment, the inspection is performed only when ascending from the lower floor to the upper floor, but in the second embodiment, in a case where a phenomenon indicating an abnormality has occurred, the robot control section 104 of the mobile body 100 instructs the control device 50 of the escalator 10 to reverse the movement of the steps 30 from ascending to descending.

[0064] Then, while the mobile body 100 is mounted on the steps 30 and moving from the upper floor to the lower floor, the robot control section 104 can also re-inspect whether the abnormal phenomenon occurring at the time of ascending has occurred at the same position.

[0065] At this time, since the position (number of the identifier) where the abnormal phenomenon has occurred is identified at the time of the inspection of ascending, the robot control section 104 can also perform the inspection only at that position at the time of descending. Further, it is also possible to re-perform the inspection again at all the positions where the marks 70 to which the identifiers 9 to 1 are attached from the upper floor to the lower floor.

[0066] By thus performing the reverse operation, the mobile body 100 can perform the inspection more accurately.

[0067] (Modified example)

[0068] Next, the modified examples of the above-described embodiments will be described in order.

[0069] In the above-described embodiments, the marks 70 are attached to only one of the rails 36, but it is also possible to attach the marks 70 to both of the left and right rails 36, 36, and the robot control section 104 recognizes the position of itself by recognizing the left and right marks 70, 70 by the camera 110. In this case, even in a case where the mark 70 of one of the left and right sides is peeled off or contaminated, it is possible to recognize the position of the mobile body 100.

[0070] Further, in the above-described embodiments, the abnormal vibration and the abnormal sound are taken as the inspection targets, but it is not limited thereto, and it is also possible to capture the steps 30, the rails 36, and the skirt guard 44 by the camera 110, and the robot control section 104 detects the damage or the contamination of these members by performing image recognition on these images.

[0071] Further, in the above-described embodiments, the tear-drop type is shown as the mark 70 for indicating the direction, but it is not limited thereto, and it is also possible to be other shapes, such as an arrow shape, as long as the up-and-down direction can be indicated.

[0072] Further, in the above-described embodiments, the number indicated by the mark 70 is such that the numerator is the number of the identifier, and the denominator is the total number of the marks 70, but in addition thereto, it is also possible to indicate the number of the installed floors of the escalator 10 (for example, information such as 1st floor to 2nd floor, 2nd floor to 3rd floor, and the like).

[0073] Further, in the above embodiment, the label as the marker 70 is attached to the upper portion of the railing 36, but is not limited thereto, and can be attached to the lower portion of the railing 36 or the skirt guard (inner cover) 44.

[0074] Further, in the above embodiment, the marker 70 is a label, but is not limited thereto, and can be a radio wave transmission device or an ultrasonic wave transmission device installed at regular intervals inside the railing 36, inside the skirt guard 44, or on the handrail track 39 or the guide rail 25. In this case, the radio wave transmission device or the ultrasonic wave transmission device transmits a marker indicating the installation position thereof in a radio wave or an ultrasonic wave. In the case where the marker 70 is the radio wave transmission device, the reception is performed by the robot communication section 118, and in the case where the marker 70 is the ultrasonic wave transmission device, the reception is performed by the microphone 112.

[0075] Further, in the above embodiment, the inspection is performed while the mobile body 100 ascends from the lower layer to the upper layer, but the inspection can be performed while descending from the upper layer to the lower layer.

[0076] Further, in the above embodiment, the mobile body 100 is moved from the lower layer to the upper layer even if an abnormal phenomenon occurs, but is not limited thereto, and can be such that, in the case where an abnormal phenomenon occurs, the mobile body 100 stops at the position and reports to the outside that there is an abnormality from there.

[0077] Further, in the above embodiment, the steps 30 are moved at the rated speed. However, since the intervals of the markers 1 to 9 are determined in advance, the mobile body 100 can accurately recognize the position of the abnormal phenomenon even if the inspection is performed at a speed faster than the rated speed or a speed slower than the rated speed without performing the normal operation at the rated speed at the time of the inspection.

[0078] Further, in the above embodiment, the application to the escalator 10 is described, but the application to the moving sidewalk can be made instead.

[0079] The above describes one embodiment of the present application, but the embodiment is suggested as an example and is not intended to limit the scope of the application. The new embodiments can be implemented in other various ways, and various omissions, substitutions, and changes can be made within the scope of the gist of the application. The embodiments and modifications thereof are included in the scope and gist of the application, and are included in the scope of the application and equivalents thereof recited in the patent claim.
