[0024] (I) First embodiment

[0025] Hereinafter, an embodiment of the present application will be described in detail. However, the present application is not limited to the embodiment.

[0026] The passenger conveyor of the present embodiment has a passenger guidance system. The passenger guidance system, for example, determines whether a passenger of the passenger conveyor is an object that should be guided (hereinafter, referred to as "guidance object") before boarding, and prompts (guides) the passenger to board in a correct posture (hereinafter, referred to as "boarding posture"). As one mode, the present passenger guidance system has a detector for acquiring a state of a passenger approaching a boarding gate, a calculation section that calculates a fall risk for determining whether the passenger falls when boarding the passenger conveyor, based on a detection signal (detection information) detected by the detector, a display that performs display for guiding the passenger to a predetermined boarding posture (hereinafter, referred to as "guidance display"), and a control section that controls the guidance display of the display based on a calculation result of the calculation section.

[0027] According to the above-described structure, for example, a passenger of the passenger conveyor who has a high fall risk when boarding can be guided to a safe boarding posture.

[0028] Hereinafter, embodiments of the present application will be described with reference to the accompanying drawings. In addition, in all the drawings used to describe the embodiments, the same symbols are assigned to the parts having the same function, and redundant descriptions are omitted as much as possible. In addition, the present application is not construed to be limited to the contents described in the following embodiments. It is easily understood by those skilled in the art that the specific structure can be changed without departing from the idea or the gist of the present application.

[0029] In order to easily understand the application, the position, size, shape, range, and the like of each structure shown in the drawings and the like are sometimes not indicative of the actual position, size, shape, range, and the like. Therefore, the present application is not necessarily limited to the position, size, shape, range, and the like disclosed in the drawings and the like.

[0030] The publications and patent documents cited in this specification directly constitute a part of the description of this specification.

[0031] In this specification, a component represented by a singular form includes a plurality of the components unless specifically indicated otherwise in the context.

[0032] The expressions "first", "second", "third", and the like in this specification and the like are assigned for the purpose of identifying the components, and are not necessarily limited to the number or the order. In addition, the numbers used for identifying the components are used in the context, and the number used in one context is not necessarily indicative of the same structure in another context. In addition, it is not excluded that the component identified by a certain number has the function of the component identified by another number.

[0033] Further, in the following description, in a case where the same elements are described without distinguishing, the common part of the reference symbols including the branch number (part other than the branch number) is sometimes used, and in a case where the same elements are described with distinguishing, the reference symbols including the branch number are sometimes used. For example, in a case where the displays are not distinguished particularly, it is described as "display 180", and in a case where the displays are distinguished, it is sometimes described as "display 180-1", "display 180-2".

[0034] Figures 1-3 is a view showing an example of the passenger conveyor 100 of the present embodiment. The passenger conveyor 100 can be a structure in which a plurality of steps are connected in a stair shape like an escalator, or can be a horizontal type structure in which a tread surface is not a stair shape like a moving walkway. Hereinafter, the escalator is described as a representative.

[0035] The passenger conveyor 100 is provided between an upper floor and a lower floor of a building, which is omitted from the illustration. Further, the passenger conveyor 100 is provided in a building, which is omitted from the illustration. Figures 1-3 shows an appearance structure in the vicinity of the landing of the lower floor.

[0036] As shown in Figure 1 , the passenger conveyor 100 has a plurality of steps 110. The steps 110 move from the lower floor toward the upper floor, or move from the upper floor toward the lower floor. In addition, the passenger conveyor 100 has a rail panel 120, a handrail 130 located at a peripheral portion of the rail panel 120, and a skirt guard 140 on both sides in the traveling direction of the steps 110 (only one side is illustrated in Figure 1 ). The lower portions of the rail panel 120 and the handrail 130 are covered by the skirt guard 140. By the skirt guard 140, a structure body such as a driving mechanism of the steps 110 and a frame assembled with the driving mechanism does not protrude to the outside between the upper floor and the lower floor, and thus safety is ensured. The handrail 130 moves in the same direction as the traveling direction of the steps 110 in synchronization with the movement of the steps 110.

[0037] Hereinafter, the structure for preventing passengers from falling from the passenger conveyor 100 and getting off midway, which is provided at the side portion of the passenger conveyor 100 and is composed of the rail panel 120, the handrail 130, and the skirt guard 140, is referred to as a "rail portion".

[0038] Additionally, the passenger conveyor 100 includes a boarding ramp 150 and a comb plate 160. The boarding ramp 150 and comb plate 160 are installed at the boarding / alighting point, extending from inside the building towards the steps 110. The boarding ramp 150 serves as a cover for the machinery room located on the ground floor and also as a passageway for passengers. The comb plate 160 is the entrance / exit for the steps 110 to access the machinery room and has comb teeth that engage with the irregularities (anti-slip plates and grooves) on the surface of the steps 110. This comb plate 160 prevents passengers' shoes from being caught at the entrance / exit.

[0039] In addition, the space on the boarding and alighting platform 150 and the space between the railing panels 120 on the left and right sides of the steps 110 is referred to as the "boarding and alighting area". In addition, at the boarding and alighting area, the space where passengers walk before boarding the steps 110 is sometimes referred to as the "boarding area", and the space where passengers walk after getting off the steps 110 is referred to as the "disembarking area".

[0040] also, Figure 1 The structure shown is in relation to Figure 1 The same applies to the opposite side (left and right) and the same applies to the boarding / alighting points on the upper floors (not shown in the diagram). This is in Figure 2 and Figure 3 The same applies to China.

[0041] Additionally, the passenger conveyor 100 includes a detector 170 that detects the status of passengers approaching the boarding gate. The detector 170 is positioned so as not to obstruct the passenger's walking path. The detector 170 is located on the side of the walking path at the boarding gate, in a space on the same plane as the handrail (denoted as "side of the boarding gate"). For example, as... Figure 1 As shown, it is installed near the entrance / exit of handrail 130. Additionally, part or all of detector 170 may be installed inside the handrail or inside the landing plate 150. Alternatively, detector 170 may also be installed on the building side (not shown in the diagram).

[0042] As detector 170, sensors that use light, radio waves, or sound for non-contact sensing and detection are employed, such as infrared range sensors, ultrasonic sensors, millimeter-wave sensors, distance image cameras, and visible light cameras. Alternatively, detector 170 can also be a pressure distribution sensor, which is a sensor with a pressure distribution sensor inside the boarding platform 150 that determines the passenger's state based on the pressure distribution. Furthermore, as described later, when skeletal information can be calculated (estimated), the risk of falling can be calculated with higher accuracy. Therefore, as detector 170, a distance image camera or visible light camera capable of calculating skeletal information can be used; preferably, a distance image camera capable of measuring the distance to an object (e.g., a passenger) is also used.

[0043] Additionally, the passenger conveyor 100 has one or more displays 180. Display 180-1 shows the step positions on the boarding ramp 150. The step positions on the boarding ramp 150 are displayed to assist passengers walking on the boarding ramp 150, and are displayed in accordance with passenger walking patterns. Hereinafter, regarding display 180-1, the platform position 101 of the boarding ramp 150 is listed as an example of the step positions on the boarding ramp 150. Figure 1 Let's take an example. Display 180-2 shows the step position 201 on step 110. Figure 2 The display 180-3 shows the gripping position 301 of the armrest 130. Figure 3 ).

[0044] The display 180-1 is a projector, LED, etc., used to project, for example, a mark indicating the level crossing position 101 onto the boarding ramp 150. Alternatively, a portion of the level crossing position 101 can be projected onto the comb plate 160. Like the detector 170, the display 180-1 is installed on the side of the boarding ramp, inside the handrail, etc. Figure 1 As an example, a display 180-1 is installed inside the railing section (skirt panel 140).

[0045] The display 180-2 is a projector, LED, etc., used to project, for example, a mark indicating the step position 201 onto the step 110. Like the detector 170, the display 180-2 is installed on the side of the boarding area, inside the handrail, etc. Figure 1 As an example, a display 180-2 is installed inside the railing section (e.g., apron panel 140).

[0046] Furthermore, displays 180-1 and 180-2 can also be installed on the side of the building (ceiling, etc.). Additionally, displays 180-1 and 180-2 are not limited to image projection; they can also be used to illuminate LEDs embedded in the steps 110 or the landing plate 150. The shapes of the level crossing position 101 and the stepping position 201 can be any shape or pattern, such as circular markers, square markers, or foot shapes. Furthermore, the shapes of the level crossing position 101 and the stepping position 201 can also be text images, etc. The level crossing position 101 and the stepping position 201 can be static images that always display the same image, or they can project dynamic images using a projector or the like.

[0047] The display 180-3 is a projector, an LED, a transparent display, or the like, for example, which projects an arrow indicating the gripping position 301 to the balustrade panel 120. The display on the balustrade panel 120 can be displayed at a certain specific place, or can be moved in accordance with the movement of the passenger. The display 180-3 projects an image, for example, by irradiating a light guide panel provided in the balustrade panel 120 with light. Further, the display 180-3 can also be a method of projecting a mark indicating the gripping position 301 to the surface of the handrail 130 or other projection methods.

[0048] The display 180 can show any one of the boarding position 101 of the landing plate 150, the stepping position 201 of the step 110, and the gripping position 301 of the handrail 130, or can show two or more in a manner that can guide to a more correct boarding posture by combining a plurality of displays 180. In the case of combining a plurality of displays 180, for example, the timing of the guidance display can be staggered in a manner that displays in the order of the boarding position 101 of the landing plate 150, the stepping position 201 of the step 110, and the gripping position 301 of the handrail 130, thereby guiding the passenger to concentrate in the order of the movement from the foot to the hand.

[0049] In addition, the passenger conveyor 100 has a processing portion 190. The processing portion 190 is a microcomputer, a computer, a notebook computer, a tablet terminal, or the like. The processing portion 190 is communicably connected to the detector 170, the display 180, a control panel 440 described later, or the like by wire or wirelessly. The processing portion 190 calculates the risk of falling based on the detection information obtained by the detector 170, and controls the display content of the display 180 to guide the boarding posture of the passenger based on the calculated result.

[0050] In addition, the processing portion 190 can perform switching of the running speed of the passenger conveyor 100 at the same time in addition to the control based on the guidance display of the display 180. For example, the processing portion 190 determines the presence or absence of a passenger boarding the passenger conveyor 100 based on load information of an inverter attached to the passenger conveyor 100 or the like, and in the case where it is determined that there is no passenger, performs guidance display and control to decelerate the running speed of the passenger conveyor 100. By decelerating the running speed, the passenger can more safely perform boarding.

[0051] Figure 4 is a drawing showing an example of a drive mechanism of the step 110. Further, Figure 4 shows the structure of the upper floor side. In addition, Figure 4 The passenger conveyor 100 shown in the drawing is for downward travel, and the step 110 moves from the upper floor toward the lower floor on the side where the passenger boards. As shown in Figure 4As shown, each step 110 is engaged with a ring-shaped step chain (not shown). When a sprocket 410 to which the step chain is wound is rotationally driven by a drive machine 420 provided in a machine room directly below the landing plate 150, the step chain is driven. Thereby, each step 110 is guided by a guide rail 430 and is circularly driven between the upper floor and the lower floor.

[0052] Further, the drive machine 420 has an induction machine, a synchronous machine, or the like AC motor, and rotationally drives the sprocket 410 when the AC motor is driven by an inverter device stored in a control panel 440. The AC motor can be either one of a single-phase AC motor and a three-phase AC motor.

[0053] Further, in Figure 4 the sprocket 410 is rotated to the left in the drawing (refer to the arrow). Thereby, the passenger conveyor 100 is operated as a downgoing one.

[0054] In order to control the display timing of the guidance display based on the display 180-1 and the display 180-2, a step detector that detects the position of the step 110 of the passenger conveyor 100 is preferably provided. In particular, when the display 180-1 or the display 180-2 displays the crossing position 101 of the landing plate 150 or the stepping position 201 of the step 110, the display timing needs to be controlled with high precision so that the passengers do not get on the boundary between the steps 110 or the like. As an example of the step detector, a proximity sensor 450 is provided in a frame in which the step 110 and its driving mechanism are arranged. When a predetermined portion (for example, a step shaft) of the step 110 opposes the proximity sensor 450, the proximity sensor 450 outputs a detection signal. Further, as the proximity sensor 450, a non-contact sensor such as an induction current type (for example, an eddy current type), an electrostatic capacitance type, an optical type, or the like can be applied.

[0055] Figure 5 is a diagram showing an example of the functional structure of the processing section 190. The processing section 190 has a storage section 510, a calculation section 520, and a control section 530.

[0056] The storage section 510 stores detection information 511, skeleton information 512, one or more parameters 513, and a threshold value 514. The storage section 510 can also store a determination model 515. The detection information 511 is information detected by the detector 170. The skeleton information 512 is information indicating the skeleton of the passenger, and is calculated by the calculation section 520 from the detection information 511.

[0057] The parameter 513 is information used for calculating the fall risk, which is calculated by the calculation section 520 from the detection information 511 or the bone information 512. Further, the fall risk can be one or more of the parameters 513, the comprehensive parameter α' described later, or the like, or a value numerically expressed from the parameter 513. Hereinafter, the parameter 513 is sometimes referred to as αi. α1 indicates the pace of the passenger. α2 indicates the walking speed of the passenger. α3 indicates the walking cycle of the passenger. α4 indicates the walking variation of the passenger. α5 indicates the bending of the waist of the passenger. α6 indicates the orientation of the face of the passenger. α7 indicates the estimated age of the passenger. α8 indicates the presence or absence of the belongings of the passenger. α9 indicates the height of the passenger. α10 indicates the standing still time of the passenger. Further, the parameter 513 is not limited to the above. The threshold value 514 is a determination value used for evaluating the fall of the passenger when boarding the passenger conveyor 100. The threshold value 514 is set in correspondence with αi, and is sometimes referred to as αi, h.

[0058] The determination model 515 is a determination model for determining the guide object using the parameter 513, which is learned by an algorithm of machine learning. Here, the algorithm of machine learning is the nearest neighbor method, the Naive Bayes model, the decision tree, the SVM (Support Vector Machine), the neural network, or the like. Further, the processing section 190 can have a learning section that generates the determination model by learning a plurality of parameters 513 by the algorithm of machine learning.

[0059] The calculation section 520 calculates the parameter 513 (the fall risk) such as the pace of the passenger from the detection information 511 of the passenger detected by the detector 170. In the case where the detector 170 is the distance image sensor, the calculation section 520 calculates the bone information 512 from the detection information 511, and calculates the parameter 513 using the bone information 512.

[0060] The control section 530 compares the parameter 513 calculated by the calculation section 520 with the threshold value 514, and determines whether or not it is the guide object. Further, the control section 530 can determine whether or not it is the guide object using the parameter 513 and the determination model 515. Then, the control section 530 controls the display content of the display 180 based on the result of the determination. In other words, the control section 530 controls the display 180 so as to perform the guide display in accordance with the fall risk.

[0061] Figure 6 is a diagram showing an example of the hardware structure of the processing section 190. The processing section 190 has a processor 601, a main storage device 602, an auxiliary storage device 603, an input device 604, an output device 605, and a communication device 606.

[0062] The processor 601 is a device that performs arithmetic processing. The processor 601 is, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a GPU (Graphics Processing Unit), an AI (Artificial Intelligence) chip, or the like.

[0063] The main storage device 602 is a device that stores programs, data, and the like. The main storage device 602 is, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), or the like. The ROM is an SRAM (Static Random Access Memory), an NVRAM (Non Volatile RAM), a mask ROM, a PROM (Programmable ROM), or the like. The RAM is a DRAM (Dynamic Random Access Memory), or the like.

[0064] The auxiliary storage device 603 is a hard disk drive, a flash memory, an SSD (Solid State Drive), an optical storage device, or the like. The optical storage device is a CD (Compact Disc), a DVD (Digital Versatile Disc), or the like. Programs, data, and the like stored in the auxiliary storage device 603 are read into the main storage device 602 as occasion demands.

[0065] The input device 604 is a user interface that accepts information from a user. The input device 604 is, for example, an optical drive, a card reader, a keyboard, a mouse, a touch panel, or the like. Furthermore, the processing section 190 can not have the input device 604.

[0066] The output device 605 is a user interface that outputs (display outputs, print outputs, and the like) various kinds of information. The output device 605 is, for example, a display device that visualizes various kinds of information, a printing device, or the like. The display device is an LCD (Liquid Crystal Display), a graphics card, or the like. Furthermore, the processing section 190 can not have the output device 605.

[0067] The communication device 606 is a communication interface that communicates with other devices via a communication medium. The communication device 606 is, for example, a NIC (Network Interface Card), a wireless communication module, a USB (Universal Serial Interface) module, a serial communication module, or the like. The communication device 606 can also function as an input device that receives information from other devices that can be communicably connected. In addition, the communication device 606 can also function as an output device that transmits information to other devices that can be communicably connected.

[0068] The functions of the processing section 190 (the storage section 510, the calculation section 520, the control section 530, and the like) can be implemented, for example, by the processor 601 reading out a program stored in the auxiliary storage device 603 to the main storage device 602 and executing (software), by hardware such as a dedicated circuit, or by a combination of software and hardware.

[0069] Further, one function of the processing section 190 can also be divided into a plurality of functions, and a plurality of functions can also be aggregated into one function. In addition, a part of the functions of the processing section 190 can be provided as other functions, or can be included in other functions. In addition, a part of the functions of the processing section 190 can also be implemented by another computer that can communicate with the processing section 190.

[0070] In addition, the program related to the control of the processing section 190 described above is provided by a recording medium such as the CD-ROM 610, a data signal such as the Internet. The processing section 190 receives the provision of the program via the CD-ROM 610. In addition, the processing section 190 has a connection function with the communication line 620. The computer 630 is a server computer that provides the above program, and stores the program in a recording medium such as the storage device 640. The communication line 620 is a communication line such as the Internet, a personal computer communication, a dedicated communication line, or the like. The computer 630 reads out the program from the storage device 640 and transmits the program to the processing section 190 via the communication line 620. That is, the computer 630 transmits the program as a data signal via a carrier wave via the communication line 620. In this way, the program is supplied as a computer program product that can be read by a computer in various forms such as a recording medium, a data signal (carrier wave), and the like.

[0071] Next, the use of the detection information 511 obtained by the detector 170 will be described. Figures 7-11 A method of calculating the fall risk of the passenger from the detection information 511 obtained by the detector 170, and determining whether or not it is a guidance target will be described. In the following assumptions, it is described that the fall risk is calculated by the calculation section 520, and the control section 530 determines whether or not it is a guidance target, and controls the display content of the display 180.

[0072] Figure 7is a view showing an example of a process of controlling the display content of the display 180 based on the detection information 511. Here, as an example, a method in a case where the detector 170 uses a distance image sensor is described.

[0073] In step S701, the storage section 510 acquires a distance image (an example of the detection information 511) from the detector 170 and stores it in the auxiliary storage device 603.

[0074] In step S702, the calculation section 520 calculates the parameter 513 (a fall risk) based on the distance image. The calculation section 520 can calculate the parameter 513 without calculating the bone information 512 or can calculate the parameter 513 with the calculation of the bone information 512.

[0075] For example, the calculation section 520 calculates the parameters 513 (ai) such as a walking movement (a stride, a walking speed, a walking cycle, and the like), a posture (a bending of the waist, an orientation of the face, a tilt of the body, and the like), an estimated age, a height, the presence or absence of an article, a stop time before boarding the passenger conveyor 100, and the like based on the detection information 511 of the detector 170.

[0076] In step S703, the control section 530 determines whether or not it is a guidance target (determines whether or not there is a risk of falling). The control section 530 transfers the process to step S704 in a case where it is determined that it is a guidance target, and does not perform a guidance display process and ends the process in a case where it is determined that it is not a guidance target. More specifically, the control section 530 determines whether or not the parameter 513 is the threshold value 514 or more based on the size relationship between the parameter 513 (ai) and the threshold value 514 (ai, h) when determining whether or not it is a guidance target.

[0077] In step S704, the control section 530 performs a guidance display process. In addition, regarding the guidance display process, the use of Figure 8 is described later.

[0078] Figure 8 is a view showing an example of a guidance display process.

[0079] In step S801, the control section 530 determines a place (a display place) where guidance display is performed for each display 180. For example, in a case where the passenger is detected to be on the left side with respect to the traveling direction by the detector 170 as in the display modes 1020, 1030 exemplified above, the control section 530 determines to display the stepping position 201 on the left side of the landing plate 150, to display the stepping position 201 on the left side of the step 110, and to display the gripping position 301 on the left side of the handrail 130. Figure 10

[0080] ​Further, the display location can be determined before the step S804 and the step S806 described later. For example, in a case where the detector 170 detects an action of extending the right hand toward the handrail 130, the control section 530 determines that the right side is approached and determines to display the stepping position 201 on the right side of the step 110. Further, for example, in a case where the detector 170 detects that the line of sight is directed toward the right side of the handrail 130, the control section 530 determines that the right side is approached and determines to display the gripping position 301 on the right side of the handrail 130. In this way, the control section 530 determines the display location in accordance with at least one of the approaching direction of the passenger, the movement of the arm of the passenger, and the line of sight of the passenger, and performs the guidance display of the position suitable for each passenger.

[0081] In the step S802, the control section 530 displays the crossing position 101 at the display location determined in the step S801 in accordance with the position of the step 110. Further, the relationship (display timing) of the position of the step 110 and the display of the crossing position 101 is determined using the following expression. Figure 9 This will be described later.

[0082] In the step S803, the control section 530 determines whether the passenger approaches the boarding place of the passenger conveyor 100 (for example, the passenger reaches a predetermined distance from the comb plate 160). The control section 530 transfers the process to the step S804 in a case where it is determined that the passenger approaches the boarding place of the passenger conveyor 100, and transfers the process to the step S802 in a case where it is determined that the passenger does not approach the boarding place of the passenger conveyor 100.

[0083] In the step S804, the control section 530 displays the stepping position 201 at the display location determined in the step S801 in accordance with the position of the step 110. Further, the relationship (display timing) of the position of the step 110 and the display of the stepping position 201 is determined using the following expression. Figure 9 This will be described later.

[0084] In the step S805, the control section 530 determines whether the passenger boards the passenger conveyor 100. The control section 530 transfers the process to the step S806 in a case where it is determined that the passenger boards the passenger conveyor 100, and transfers the process to the step S804 in a case where it is determined that the passenger does not board the passenger conveyor 100. Further, although not illustrated, the passenger conveyor 100 can be provided with a boarding detector that detects boarding of the passenger conveyor 100 by the passenger. The control section 530 determines that the passenger boards the passenger conveyor 100 in a case where the passenger is detected by the boarding detector. The boarding detector is a photoelectric sensor, a visible light camera, a vibration sensor, a pressure sensor, or the like. The boarding detector is provided to a side portion of the boarding port, an inside of the railing portion, a building, or the like.

[0085] In step S806, the control section 530 displays the holding position 301 at the display location decided in step S801.

[0086] Further, the guide display processing is not limited to the above-described processing. For example, step S806 can be performed before step S805. In this case, the control section 530 can display the holding position 301 according to the position of the step 110 (for example, a case where a part of the step 110 appears from the comb plate 160 before the step 110 appears from the comb plate 160).

[0087] Figure 9 is a drawing showing an example of processing for explaining the timing of guide display. Each of steps S802 and S804 is repeatedly executed at a predetermined cycle.

[0088] In step S901, the control section 530 acquires detection information of the proximity sensor 450 (step detector).

[0089] In step S902, the control section 530 calculates (measures) the position of the step 110 from the detection information acquired in step S901.

[0090] In step S903, the control section 530 determines whether it is a display timing according to the timing of detecting the step 110. The control section 530 transfers the processing to step S904 in a case where it is determined to be the display timing, and ends the processing without guide display in a case where it is determined not to be the display timing.

[0091] The display timing of the crossing position 101 is the timing at which a part or all of the step 110 appears from the comb plate 160 in a case where the passenger reaches the first place (for example, the passenger reaches 2 m in front of the comb plate 160). The display timing of the stepping position 201 is the timing at which a part or all of the step 110 appears from the comb plate 160 in a case where the passenger reaches the first place or the second place.

[0092] In step S904, the control section 530 determines whether both the display timing determination (the determination result of step S903) and the fall risk determination (the determination result of step S703) are "Yes". The control section 530 transfers the processing to step S905 in a case where it is determined that both are "Yes", and ends the processing in a case where either is "No".

[0093] In step S905, the control section 530 performs the guide display. Further, the control section 530 displays the crossing position 101 in step S802, and displays the stepping position 201 in step S804. For example, with respect to the crossing position 101, after the passenger arrives at the first place, until the passenger arrives at the second place (for example, a place at a predetermined distance from the comb plate 160, one step away from the step 110), a predetermined time (for example, 0.3 seconds) is displayed every time the step 110 appears. In addition, for example, with respect to the stepping position 201, after the passenger arrives at the first place or the second place, until the passenger gets on the step 110, a predetermined time is displayed every time the step 110 appears.

[0094] Further, Figures 7 to 9 The illustrated processing is an example, and various variation modes of the flowchart are considered in the case of adding a sensor.

[0095] Figure 10 is a diagram indicating a case where the guide display to the step 110 is switched according to the state of the passenger (an example of a display mode).

[0096] The display mode 1010 indicates a case where a healthy person gets on. For example, with respect to the walking speed or the like, the person walks with a condition of a threshold value or more, and thus the control section 530 determines not to perform the guide display to the passenger.

[0097] The display mode 1020 indicates a case where a passenger who is a guide object gets on. Since there is no confidence in getting on, the person looks at the step 110, walks with the face down, and approaches at a slow walking speed with a narrow pace. For such a passenger, the control section 530 determines that the risk of falling is high, and performs the guide display. With respect to the determination of the guide object, the control section 530 determines by the following exemplified method.

[0098] As a characteristic walking motion that can be seen by a passenger who is at high risk of falling, there are characteristics such as a slow walking speed and a small pace, and thus when α1 is α1, h (for example, 35 cm) or less with respect to the pace, and α2 is α2, h (for example, 1.0 m / s) or less with respect to the walking speed, the control section 530 determines that the passenger is a guide object. Further, the control section 530 can determine that the passenger is a guide object when either the pace or the walking speed satisfies the condition.

[0099] In addition, it is known that when the walking variation (variation in the stride, walking speed, walking cycle, etc. of each walk) is large, the risk of falling during walking is high. The calculation section 520 calculates the walking variation, such as the stride, walking speed, walking cycle, etc. of each walk, based on the variation coefficient (standard deviation / average x 100), respectively. It is preferable that, with respect to the walking variation, when a4 (for example, the variation coefficient) is a4, h (for example, 3.5%) or more, the control section 530 determines that it is a guidance target. Further, in the case of a single leg injury, etc., walking variation occurs between the left and right legs. In preparation for such a case, the calculation section 520 calculates the difference in the average of the stride, walking speed, walking cycle, etc. between the left and right legs, and the control section 530 determines that it is a guidance target in the case where the difference is the standard deviation or more calculated per leg.

[0100] In addition, as shown in the display mode 1030, with respect to a passenger who does not have confidence in boarding the passenger conveyor 100, in order to calculate the boarding timing, the walking speed is sometimes gradually decelerated, or the stride is made narrow, or stopped before boarding the passenger conveyor 100, when approaching the passenger conveyor 100. In order to guide such a passenger, with respect to the average of the stride, walking speed, walking cycle, etc. from the start point of the passenger conveyor 100 to a point that is a predetermined distance (for example, 2 m) or more away, the control section 530 determines that it is a guidance target in the case where the average measured at a point that is closer than the predetermined distance is less than the average, and the difference is the standard deviation or more. Alternatively, with respect to a passenger who completely stops before boarding the passenger conveyor 100 to calculate the timing, it should be a guidance target, and the control section 530 determines that it is a guidance target in the case where a10 is a10, h (for example, 0.4 s) or more.

[0101] The walking dynamics described above are mainly based on the dynamics of the activity of the legs, but the control section 530 can also determine based on the activity of the arms. For example, taking the walking variation as an example, the control section 530 compares the average of the arm swing amplitude, arm swing speed, arm swing cycle, etc., and determines that it is a guidance target in the case where there is a difference of the standard deviation or more calculated per arm.

[0102] In addition, in the case where the passenger is holding a cargo, contact friction occurs due to the cargo being sandwiched between the railing panel 120 and the body, and there is a risk of falling. Therefore, the control section 530 can also determine the guidance target based on the presence or absence of the possession. In particular, in the case where the passenger is holding a cargo on the same side as the handrail 130 that the passenger wants to grab (for example, in the case where a passenger who wants to grab the handrail 130 located on the left with respect to the traveling direction is holding a bag in the left hand), it is preferable that the control section 530 determines that it is a guidance target. Also, in particular, a passenger holding a walking stick has a high risk of falling, so the control section 530 determines that it is a guidance target.

[0103] Further, regarding the posture, it is known that the inclination of the torso due to the bending of the waist or the like is also related to the fall risk. In a case where the inclination of the torso or the upper body is equal to or more than a predetermined angle (for example, 5°), the control section 530 determines that the guidance target is present.

[0104] It is known that the fall risk is high particularly for the elderly, and depends on the age. Therefore, regarding the estimation of the age, for example, in a case where α7 calculated by the face, posture estimation or the like of the visible image is α7, h (for example, 65 years old) or more, the control section 530 determines that the guidance target is present.

[0105] In the above description, as the determination method of the fall risk, a specific numerical value is used as the reference, but of course, a threshold value 514 other than the above can also be used. Further, in the above description, the method of determining the guidance target by one parameter 513 is described, but it can also be that the calculation section 520 calculates a comprehensive parameter α' (fall risk) by the operation (addition operation, subtraction operation, multiplication operation, division operation, or the like) of a plurality of parameters 513 (αi). The control section 530 determines the guidance target by the size relationship with the threshold value 514 (αi, h') stored in the storage section 510. The control section 530 can determine the guidance target with high precision by using a plurality of parameters 513 (indicators). Further, the control section 530 can determine the guidance target by using a determination model 515 or the like so that the determination can be made with higher precision.

[0106] Further, here, one threshold value 514 is prepared, and the presence or absence of the guidance display is switched by the threshold determination, but it can also be a structure in which a plurality of threshold values 514 are prepared, and the display content is switched in a plurality of stages. For example, it can also be a structure in which the display is switched in a plurality of stages in such a manner that the display of the step 110 is performed only for the passenger with a small step width, and the display of the handrail 130 is performed in addition to the step 110 for the passenger who temporarily stops in front of the boarding port.

[0107] As described above, the calculation section 520 calculates each parameter 513 (fall risk) from the detection information 511 of the detector 170. At this time, when the passenger's bone information 512 can be extracted by the distance image sensor or the like, a plurality of parameters 513 described above can be calculated at the same time. For example, the calculation section 520 calculates the parameters 513 (fall risk) from the bone information 512. Figure 11 For example, the method of calculating the parameter 513 indicating the state of the passenger from the bone information 512 is described.

[0108] Figure 11 is a diagram indicating the case where the bone positions of the passenger approaching the passenger conveyor 100 are calculated from the image captured by the detector 170 (distance image camera or visible light camera) provided near the boarding port (one example of the image). In Figure 11In the illustrated images 1110, 1120, 1130, a joint position "·" is shown in the passenger image 1101. The joint position indicates a result of calculating a skeleton of a person using deep learning or the like from a distance image, a visible image, or these dynamic images.

[0109] As Figure 11 indicated, the names of the joint positions are indicated by L: leg (Leg), A: arm (Arm), H: head (Head), and C: center (Center). Subscripts of the names of the joint positions indicate l: left (Left), r: right (Right), and a skeleton number. For example, the left hand is denoted by Al 1, and the right knee is denoted by Lr 2. In a case where the distance image camera is used as the detector 170, the calculation section 520 can calculate X, Y, Z coordinates of each skeleton position, and can calculate the skeleton position with high precision.

[0110] Figure 11 A case where an image is captured from a direction inclined with respect to a traveling direction is shown, and of course, a traveling direction on a screen differs depending on a setting position and a setting angle of the detector 170. In the following description, for simplicity, a case where an image is captured from the front with respect to the traveling direction is assumed. That is, the detector 170 is set to face a passenger, and a distance by which the passenger moves in the traveling direction per unit time coincides with a reduction amount of a distance from the detector 170 to the person.

[0111] Figure 11 The illustrated image 1110 indicates a case where a passenger is walking normally. A method of calculating a step, a walking speed, a walking cycle (pace), a swinging arm, and the like using the image 1110 is described.

[0112] With respect to the step, the calculation section 520 calculates, for example, from a time series change of the leg coordinates Lr 1, Ll 1. For example, the calculation section 520 obtains a case where Lr 1, Ll 1 alternately shorten a distance when investigating a time change of a distance to the detector 170. When a distance of a landing point of the right leg of the first step in a certain walking path is set to Lr 1(1), and a distance of a landing point of the left leg of the second step is set to Ll 1(2), the calculation section 520 calculates a step from |Lr 1(1) - Ll 1(2)|. In addition, the calculation section 520 can calculate a step from an average of steps of several steps, such as |Lr 1(1) - Lr 1(3)| / 2.

[0113] With respect to the walking speed, the calculation section 520 calculates from a time series change of the C 1 coordinate indicating a center of a torso, an average of a plurality of coordinates, or the like. As an example, the calculation section 520 measures a time t to pass through a certain specified section (section length D), and calculates a walking speed from D / t.

[0114] As for the walking cycle, the calculation section 520 performs the calculation from the time-series change of the coordinates of the legs Ll1 to Lr3. In walking, since the left leg and the right leg are moved alternately, in a graph of the time-series change, the motions of Ll1 to Ll3 and the motions of Lr1 to Lr3 appear alternately. Therefore, the calculation section 520 can calculate the walking cycle from the appearance cycle of the motions of the respective coordinates.

[0115] By applying the above-described calculation process of the legs based on the stride and the walking cycle to the arms as well, the calculation section 520 can calculate the swing arm cycle and the swing arm amplitude. In this case, the calculation section 520 performs the calculation using the time-series change of the arm coordinates Al1 to Ar2. In addition, the calculation section 520 can calculate the walking variation from the above-described walking dynamics.

[0116] The image 1120 shows a case where the passenger walks with a walking stick. Using the image 1120, the posture estimation in walking such as the bending of the waist, the orientation of the face, the inclination of the body, the passenger height estimation, and the possession estimation are described.

[0117] In the case of the bending of the waist, the upper body is in a forward-leaning posture, and thus appears as a difference in the distance between the upper body coordinates and the lower body coordinates. For example, the calculation section 520 calculates a first distance from the detector 170 to the body center Cl and a second distance to the root portions Lr3 and Ll3 of the left and right legs when walking in a certain specified range. When the first distance is shorter than the second distance, it is known that the passenger walks with the bending of the waist since it is a walking manner of the forward-leaning posture.

[0118] As for the orientation of the face as well, the calculation section 520 calculates a first distance from the detector 170 to the body center Cl and a second distance from the detector 170 to the face center C2. The calculation section 520 can calculate the up-and-down angle of the face from the difference between the first distance and the second distance. As for the left-and-right angle, the calculation section 520 performs the calculation, for example, from the horizontal positional offset of the body center Cl and the face center C2. In addition, the calculation section 520 can perform the calculation from the distances from the detector 170 to the face side portions Hr1 to Hl2, and calculate the left-and-right angle from the difference between the face left portion (Hl1, Hl2) and the face right portion (Hr1, Hr2).

[0119] As for the inclination of the body, for example, the person in the image 1120 performs a walking manner of the right-side inclination, and at this time, the height of the root portion Lr3 of the right leg is different from the height of the root portion Ll3 of the left leg. Alternatively, it also appears as a difference in the height of the left arm (Al1, Al2) and the right arm (Ar1, Ar2). The calculation section 520 can calculate the inclination of the body from these differences.

[0120] As for the height, the calculating section 520 calculates, for example, from the height of the body center Cl or the head center C2.

[0121] As for the belongings, in the case where the passenger holds the belongings with one arm, the swing cycle, the swing amplitude, and the like of the left and right arms are different, and thus the calculating section 520 calculates from the time-series change of the left and right arms Al 1 to Ar2. In addition, in the case where the passenger holds the belongings with a cane, the motion of the arm at the time of stepping out becomes a characteristic motion of protruding the arm forward, and thus the calculating section 520 can also calculate from such a motion of the arm.

[0122] As for the case where the passenger has other belongings, in the image 1130, a case where the passenger holds a bag and walks is shown, and the passenger holds the bag by bending the right elbow joint. In this case, in the walking of several steps, the passenger walks in a state where the joint angle of the arm is bent, and thus the calculating section 520 can also calculate the presence or absence of the belongings by calculating the joint angle.

[0123] The calculation method of the parameter 513 described above is an example, and is not necessarily limited to the above-described calculation method. The calculating section 520 can also calculate the walking dynamics, the posture, and the like from a plurality of parameters 513. For example, the calculating section 520 can also calculate from the motion of Ll 2 to Lr3 in order to calculate the stride, and can calculate with higher accuracy by combining with the time-series change data of Ll 1 and Lr 1.

[0124] In addition, in the case where there is a correlation between the parameters 513, the calculating section 520 can also calculate the parameter 513 of the other side from the parameter 513 of one side. For example, the walking speed, the walking cycle, and the stride are in a relationship of stride (m) = walking speed (m / s) x walking cycle (s), and thus the calculating section 520 can calculate the remaining one parameter 513 on the basis of two parameters 513. In another example, the walking cycle and the swing cycle have a correlation, and thus the calculating section 520 can calculate the value of the other side from the value of one side. In addition, the calculating section 520 can also calculate the age of the passenger from the bending angle of the waist and the height.

[0125] In the above description, the calculation method is described on the assumption that the passenger is photographed from the front, and of course, the calculation method differs depending on the setting position and the setting angle of the detector 170. For example, in the case where the passenger is photographed from the side, the calculating section 520 can calculate the height from the height of the head center C2. Figure 11In the above-described embodiment, the calculation section 520 calculates the walking speed of the passenger walking in the advancing direction based on the depth distance from the detector 170 to the person, but in the case where the passenger is photographed from the side, the calculation is made based on the moving distance in the horizontal direction since the passenger crosses the detector 170 in the horizontal direction. In addition, the calculation section 520 can calculate the state of the passenger with higher accuracy by combining a plurality of detectors 170. In addition, the angle of view captured by the detector 170 alone has a limit, and therefore it is preferable to provide detectors 170 on both sides to reduce the dead angle.

[0126] In addition, with respect to the above-described method, the skeleton information 512 is calculated using the distance image sensor, and each parameter 513 is calculated based on the skeleton information 512, but the type of the detector 170 used is not limited to the distance image sensor. For example, in the case where a millimeter wave sensor is used as the detector 170, the distance and the moving speed of the measurement target can be detected, and therefore the calculation section 520 can calculate the step width, the walking speed, the walking cycle, the swinging speed, the swinging cycle, and the like. In addition, an ultrasonic sensor, a distance measuring sensor, or the like can be used as the detector 170 to detect the position of the passenger, and the calculation section 520 can calculate the walking speed and the stop time. By using a plurality of detectors 170, it is possible to reduce the dead angle or to robustly measure the change in the use environment. In addition, by using a visible light camera as the detector 170 to acquire a face image, the calculation section 520 can make the age estimation more accurate. With respect to all the articles, the calculation section 520 can also calculate the type of the article such as a walking stick, a bag, and the like with high accuracy by using deep learning or the like from the visible image.

[0127] In addition, the present application is not limited to the above-described embodiments, and includes various modifications. For example, the above-described embodiments are described in detail in order to easily understand the present application, and are not limited to necessarily having all the structures described. In addition, a part of the structure of an embodiment can be replaced with the structure of another embodiment, and in addition, the structure of another embodiment can be added to the structure of an embodiment. In addition, with respect to a part of the structure of each embodiment, addition, deletion, replacement, or the like of another structure can be made.

[0128] In addition, the above-described passenger guidance system is not limited to escalators, and can also be applied to moving walks.

[0129] According to the present embodiment, it is possible to guide the boarding posture to a passenger who has a high risk of falling.

[0130] (II) ADDENDUM

[0131] In the above-described embodiments, for example, the following contents are included.

[0132] In the above-described embodiments, the application of the present application to the passenger conveyor has been described, but the present application is not limited thereto and can be widely applied to various systems, apparatuses, methods, and programs.

[0133] In addition, in the above-described description, programs, tables, files, and the like that realize each function can be stored in a storage device such as a memory, a hard disk, an SSD (Solid State Drive), or the like, or a recording medium such as an IC card, an SD card, a DVD, or the like.

[0134] The above-described embodiments have, for example, the following characteristic structures.

[0135] (1) A passenger conveyor (for example, the passenger conveyor 100) has: a detector (for example, the detector 170) that detects a passenger who approaches a boarding gate of the passenger conveyor; a display (for example, the display 180) that performs a guidance display for guiding the passenger to a predetermined boarding posture; a calculation section that calculates a fall risk (for example, one or more parameters 513, a comprehensive parameter a') for determining whether the passenger falls when boarding the passenger conveyor using detection information (for example, the detection information 511) detected in the detector; and a control section (for example, the control section 530) that controls the display to perform the guidance display in accordance with the fall risk calculated by the calculation section (for example, in a case where the parameter 513 is compared with a threshold value 514, and in a case where the parameter 513 is equal to or greater than the threshold value 514, the parameter 513 and a determination model 515 are used to determine that the passenger is a guidance target).

[0136] Further, the place where the passenger boards the passenger conveyor is a place related to boarding the passenger conveyor. For example, the place can be a place where the passenger moves from a landing plate to a step, can be within a predetermined distance (for example, 1 m before the comb plate, 1 m after the comb plate, or 1 m before and after the comb plate) from a predetermined location of the passenger conveyor, or can be another place.

[0137] In the above-described structure, for example, a passenger who is likely to fall when boarding the passenger conveyor can be guided to perform the guidance display, and the passenger can visually grasp the boarding posture by the guidance display, so that the passenger can be prevented from falling when boarding.

[0138] In addition, for example, a passenger who is less likely to fall when boarding the passenger conveyor can sometimes feel inconvenienced by the guidance display. In this regard, according to the above-described structure, a passenger who is likely to fall when boarding the passenger conveyor can be guided to perform the guidance display, so that a passenger conveyor with high convenience can be provided.

[0139] (2) In a case where it is determined that the fall risk calculated by the calculation section is equal to or higher than the threshold value, the control section controls the display to perform the guide display (for example, step S703, step S704).

[0140] In the above structure, the passenger whose fall risk is equal to or higher than the threshold value is guided to be displayed, and therefore, for example, a manager of the passenger conveyor can determine the passenger who is the object of the guide display by setting the threshold value, and can be used even in a case where there is no actual data of the passenger conveyor.

[0141] (3) The calculation section calculates bone information indicating a bone of the passenger using the detection information detected in the detector (for example, bone information 512), and calculates the fall risk of the passenger based on the calculated bone information.

[0142] In the above structure, the bone information is calculated, and therefore, for example, various parameters related to the fall risk such as a stride, a walking speed, a walking cycle, and the like can be obtained.

[0143] (4) The calculation section calculates at least one of a walking pattern of the passenger, a posture of the passenger, a height of the passenger, whether or not the passenger has an article, and a stop time when the passenger rides the passenger conveyor, as the fall risk of the passenger (for example, refer to Figure 5 ).

[0144] Among the walking pattern of the passenger, the posture of the passenger, the height of the passenger, whether or not the passenger has the article, and the stop time when the passenger rides the passenger conveyor, characteristics at the time of the fall of the passenger are likely to occur, and therefore, according to the above structure, the fall risk can be calculated with high accuracy.

[0145] (5) The display displays at least one of a stepping position on a landing plate of the passenger conveyor (for example, a crossing position 101, a stepping position on a landing plate 150), a stepping position on a step of the passenger conveyor (for example, a stepping position 201), and a holding position of a handrail of the passenger conveyor (for example, a holding position 301) as the guide display.

[0146] In the above structure, at least one of the stepping position on the landing plate, the stepping position on the step, and the holding position of the handrail is displayed, and therefore, the boarding posture can be appropriately guided.

[0147] (6) The passenger conveyor described above includes a plurality of steps (e.g., steps 110) that are cyclically driven between a boarding port and a disembarking port, and a step detector (e.g., proximity sensor 450) that detects a step of the plurality of steps that appears at the boarding port, and the control portion controls the display so as to perform the guide display at the timing at which the step detector detects the step (e.g., see Figure 9 ).

[0148] In the configuration described above, the guide display is performed at the timing at which the step is detected, so for example, it is possible to reduce cases in which the passenger boards the step at the boundary.

[0149] (7) The passenger conveyor described above includes a boarding detector (photoelectric sensor, visible light camera, vibration sensor, pressure sensor, etc.) that detects that the passenger has boarded the passenger conveyor, and in a case in which the boarding detector detects that the passenger has boarded the passenger conveyor, the control portion controls the display so as to display a handhold position at a handrail of the passenger conveyor as the guide display (e.g., see step S805, step S806).

[0150] In the configuration described above, the handhold position is displayed after the passenger has boarded the passenger conveyor, so for example, at the time of boarding, the handhold position is displayed at a time at which the passenger is looking down at the floor, so it is possible to avoid causing the passenger to be distracted.

[0151] (8) The control portion controls the passenger conveyor so as to decelerate the operation speed of the passenger conveyor, based on the fall risk calculated by the calculation portion, in a case in which there is no passenger who has boarded the passenger conveyor (e.g., in a case in which it is determined that there is no boarding passenger based on detection information detected by a boarding detector, in a case in which it is determined that there is no boarding passenger based on load information of an inverter attached to the passenger conveyor, etc.).

[0152] In the configuration described above, for example, in a case in which there is no passenger who has boarded the passenger conveyor, the operation speed of the passenger conveyor is decelerated at a time at which a passenger who has a high likelihood of falling at the time of boarding approaches the boarding port, so it is possible to reduce cases in which the passenger falls at the time of boarding.

[0153] (9) The control portion decides a display location of the guide display based on at least one of the approaching direction of the passenger, the movement of the arm of the passenger, and the line of sight direction of the passenger (e.g., see step S801).

[0154] In the configuration described above, the display location of the guide display is appropriately decided based on at least one of the approaching direction of the passenger, the movement of the arm of the passenger, and the line of sight direction of the passenger, so it is possible to appropriately guide the boarding posture.

[0155] (10) The balustrade portion is provided on the side portion of the passenger conveyor, and at least one of the detector and the display is provided inside the balustrade portion (for example, refer to Figures 1-3 ).

[0156] According to the above structure, for example, in the case where the detector is provided inside the balustrade portion, it is possible to calculate the fall risk without hindering the walking of the passenger. Also, for example, according to the above structure, in the case where the display is provided inside the balustrade portion, it is possible to perform the guide display without hindering the walking of the passenger.

[0157] (11) At least one of the detector and the display is provided on the side portion of the boarding port (for example, refer to Figures 1-3 ).

[0158] According to the above structure, for example, in the case where the detector is provided on the side portion of the boarding port, it is possible to calculate the fall risk without hindering the walking of the passenger. Also, for example, according to the above structure, in the case where the display is provided on the side portion of the boarding port, it is possible to perform the guide display without hindering the walking of the passenger.

[0159] (12) The control portion controls the display so as to perform the guide display in the case where it is determined by the determination model learned by the algorithm of machine learning that the passenger is the target of the guide display using the fall risk calculated by the calculation portion.

[0160] In the above structure, the guide display is performed according to the determination model learned by the algorithm of machine learning, and thus, for example, it is possible to perform the guide display with higher accuracy.

[0161] (13) A plurality of the detectors are provided.

[0162] In the above structure, a plurality of detectors are provided, and thus, for example, it is possible to reduce the dead angle of the detector, or to robustly perform the measurement against the change in the use environment, and it is possible to perform the guide display with higher accuracy.

[0163] Also, regarding the above structure, changes, reorganizations, combinations, or omissions can be appropriately made within a range not departing from the gist of the present application.

[0164] It is to be understood that the items included in a list in the form of "at least one of A, B, and C" can represent (A), (B), (C), (A and B), (A and C), (B and C), or (A, B, and C).
