DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1 Fig. 1 is a schematic diagram showing an escalator according to embodiment 1. Fig. 1 shows an escalator installed in a commercial facility, a so-called shopping center. The operating direction of the escalator in Fig. 1 is an upward direction.

[0010] In the figure, the escalator comprises an escalator body 11 and a monitoring and control system 21.

[0011] The escalator body 11 has a truss 12, a step connector 13, a pair of left and right balustrades 14, a pair of left and right movable handrails 15, a drive unit 16, a lower floor passenger sensor 17, and an upper floor passenger sensor 18.

[0012] The truss 12 is installed between the upper and lower floors of the building. The step connector 13 is supported by the truss 12. The step connector 13 is configured by connecting a plurality of steps 13a in an endless manner. Each step 13a circulates between the upper and lower floors along a moving path. In FIG. 1, only three steps 13a out of the plurality of steps 13a are shown.

[0013] A pair of balustrades 14 are erected on the truss 12. Each moving handrail 15 is provided on the corresponding balustrade 14. Furthermore, the pair of moving handrails 15 circulate in synchronization with the movement of the multiple steps 13a.

[0014] The driving device 16 is provided at the upper floor end of the truss 12. The driving device 16 generates a driving force for moving each step 13a.

[0015] The escalator body 11 is provided with a lower floor entrance 11a and an upper floor entrance 11b. The lower floor entrance 11a is a boarding / alighting section for accessing the step connecting body 13 on the lower floor. The upper floor entrance 11b is a boarding / alighting section for accessing the step connecting body 13 on the upper floor.

[0016] In the escalator of FIG. 1, since the operating direction is an upward direction, the lower floor entrance 11a is the entrance for boarding and the upper floor entrance 11b is the exit.

[0017] The lower floor passenger sensor 17 detects passengers passing through the lower floor entrance 11a. The lower floor passenger sensor 17 is provided, for example, at the lower floor end of the balustrade 14.

[0018] The upper floor passenger sensor 18 detects passengers passing through the upper floor entrance 11b. The upper floor passenger sensor 18 is provided, for example, at the upper floor end of the balustrade 14.

[0019] Each floor of the commercial facility is provided with a plurality of facility equipment, including an anti-theft gate 51, guide railings 52, and the like.

[0020] The monitoring and control system 21 has a control device 22, a plurality of detectable tags 23, a plurality of first detection devices 24, a plurality of second detection devices 25, a plurality of displays as alarm devices, a plurality of speakers as alarm devices, and a relay connector 28.

[0021] The multiple indicators include a lower floor indicator 26a and an upper floor indicator 26b. As the lower floor indicator 26a and the upper floor indicator 26b, a display device, an LED indicator light, or the like is used.

[0022] The multiple speakers include a lower speaker 27a, an upper speaker 27b, and a middle speaker 27c.

[0023] The control device 22 is provided at the upper floor end of the truss 12. The control device 22 also controls the operation of the escalator body 11 by controlling the drive device 16. Signals from the lower floor passenger sensors 17 and the upper floor passenger sensors 18 are input to the control device 22.

[0024] The control device 22 also supplies power to each of the multiple first detection devices 24, the multiple second detection devices 25, the multiple display devices, and the multiple speakers.

[0025] There are a plurality of wheeled mobile objects in the commercial facility. Each detectable tag 23 is provided on a corresponding wheeled mobile object. In FIG. 1, a shopping cart 61 and a stroller 62 are shown as the plurality of wheeled mobile objects. The plurality of wheeled mobile objects may include a wheelchair (not shown). In this case, the wheelchair may be any of a push wheelchair, a self-propelled wheelchair, and an electric wheelchair.

[0026] A non-powered electronic component is used as each of the detection tags 23. Examples of the non-powered electronic components include an RFID (Radio Frequency Identification) tag, an electronic tag, etc. Also, each of the detection tags 23 may be a tag with a two-dimensional code.

[0027] Furthermore, the detection tag 23 may be attached in advance to each of a plurality of wheeled mobile objects, such as shopping carts 61, owned and managed by a commercial facility.

[0028] Furthermore, each detection tag 23 may be affixable to a wheeled mobile body, and can be easily attached to the wheeled mobile body. In this case, the manager of the commercial facility may lend the detection tag 23 to visitors at the entrance or exit of the commercial facility. This allows the visitors to easily attach the lent detection tag 23 to their own strollers, wheelchairs, etc.

[0029] The anti-theft gates 51 on the lower and upper floors are each provided with one or more first detection devices 24.

[0030] Each first detection device 24 on the lower floor detects the detection tag 23 in a non-contact manner to detect that a wheeled mobile object is approaching the lower floor entrance / exit 11a. Each first detection device 24 on the upper floor detects the detection tag 23 in a non-contact manner to detect that a wheeled mobile object is approaching the upper floor entrance / exit 11b.

[0031] Each of the first detection devices 24 on the lower and upper floors outputs a first detection signal when it detects a detection target tag 23. The first detection signal from each of the first detection devices 24 is input to the control device 22.

[0032] The guide handrails 52 on the lower floor and the upper floor are each provided with one or more second detection devices 25.

[0033] Each second detection device 25 on the lower floor is disposed closer to the lower floor entrance 11a than each first detection device 24 on the lower floor. Also, each second detection device 25 on the upper floor is disposed closer to the upper floor entrance 11b than each first detection device 24 on the upper floor.

[0034] Each second detection device 25 on the lower floor detects the detectable tag 23 non-contact, thereby detecting that the wheeled mobile body is closer to the lower floor boarding / alighting entrance 11a than when the first detection signal was output from each first detection device 24 on the lower floor.

[0035] Each second detection device 25 on the upper floor detects the detectable tag 23 non-contact, and thereby detects that the wheeled mobile body is closer to the upper floor boarding / alighting entrance 11b than when the first detection signal was output from each first detection device 24 on the upper floor.

[0036] Each of the second detection devices 25 on the lower and upper floors outputs a second detection signal when it detects a detection target tag 23. The second detection signal output from each of the second detection devices 25 is input to the control device 22.

[0037] When a non-powered electronic component is used as each of the detectable tags 23, each of the first detection devices 24 and each of the second detection devices 25 is a reader that reads information of the detectable tags 23. Each reader has an antenna.

[0038] When a tag with a two-dimensional code is used as each of the detectable tags 23, each of the first detection devices 24 and each of the second detection devices 25 is a camera that reads the two-dimensional code.

[0039] The lower floor display 26a is provided at the anti-theft gate 51 on the lower floor. The lower floor display 26a displays a warning to users near the lower floor entrance 11a. The upper floor display 26b is provided at the anti-theft gate 51 on the upper floor. The upper floor display 26b displays a warning to users near the upper floor entrance 11b.

[0040] The lower floor speaker 27a is provided at the lower floor entrance 11a. The lower floor speaker 27a issues an audio warning to users near the lower floor entrance 11a. The upper floor speaker 27b issues an audio warning to users near the upper floor entrance 11b.

[0041] The intermediate speaker 27c is provided at the middle of the moving path of each step 13a. The intermediate speaker 27c notifies passengers on the step connecting body 13 by voice.

[0042] The relay connector 28 is provided at the lower floor end of the truss 12. The relay connector 28 also relays transmission and reception of signals between the control device 22 and a plurality of devices provided on the lower floor.

[0043] When the control device 22 receives a first detection signal from the first detection device 24 on the lower floor, the control device 22 issues a warning to users of wheeled mobile bodies near the lower floor entrance 11a by using multiple notification devices to the effect that they are prohibited from getting on the step connecting body 13. In this case, the multiple notification devices include a lower floor display 26a and a lower floor speaker 27a.

[0044] When the control device 22 receives a first detection signal from the first detection device 24 on the upper floor, the control device 22 issues a warning to users of wheeled mobile objects near the upper floor entrance 11b by using multiple notification devices to the effect that they are prohibited from getting on the step connecting body 13. In this case, the multiple notification devices include an upper floor display 26b and an upper floor speaker 27b.

[0045] Furthermore, when the control device 22 receives a first detection signal from any of the first detection devices 24, it decelerates the step connection body 13. That is, the control device 22 switches the operation mode to a low-speed mode. The operation speed of the step connection body 13 is changed by, for example, VVVF inverter control.

[0046] At this time, the control device 22 causes the intermediate speaker 27c to generate an announcement to instruct passengers on the step connector 13 to hold onto the moving handrail 15 in order to slow down the step connector 13.

[0047] When the control device 22 receives the second detection signal from any of the second detection devices 25, it stops the step connector 13. At this time, the control device 22 issues a notification announcement from the middle speaker 27c to the passengers on the step connector 13 to grab the moving handrail 15 in order to stop the step connector 13.

[0048] A first set time and a second set time are preset in the control device 22. When the second detection signal is not input within the first set time after the first detection signal is input, and if no new user gets on the step connection 13 for the second set time or more, the control device 22 returns the speed of the step connection 13 to the rated speed. That is, the control device 22 returns the operation mode to the normal mode.

[0049] Furthermore, when the second detection signal is input without the first detection signal being input, the control device 22 determines that an abnormality has occurred in the first detection device 24.

[0050] Fig. 2 is a functional block diagram showing the control device 22 of Fig. 1. The control device 22 has, as functional blocks, a sensor control unit 22a, a signal processing unit 22b, a notification control unit 22c, a drive control unit 22d, and a central processing unit 22e.

[0051] The sensor control unit 22 a controls the lower floor passenger sensor 17 , the upper floor passenger sensor 18 , the plurality of first detection devices 24 , and the plurality of second detection devices 25 .

[0052] The signal processing unit 22 b processes signals from the lower floor passenger sensor 17 , signals from the upper floor passenger sensor 18 , signals from the multiple first detection devices 24 , and signals from the multiple second detection devices 25 .

[0053] The notification control unit 22c controls the lower floor display 26a, the upper floor display 26b, the lower floor speaker 27a, and the upper floor speaker 27b.

[0054] The drive control section 22d controls the drive device 16 to control the moving speed of the plurality of steps 13a.

[0055] The central processing unit 22e controls the sensor control unit 22a, the notification control unit 22c, and the drive control unit 22d based on information from the signal processing unit 22b.

[0056] Fig. 3 is a flow chart showing the monitoring process of the wheeled vehicle by the control device of Fig. 2. When the monitoring process is started, the control device 22 determines in step S101 whether or not the first detection signal has been input. If the first detection signal has not been input, the control device 22 repeats the process of step S101.

[0057] When the first detection signal is input, the control device 22 registers the detection of the detectable tag 23 by the first detection device 24 in step S102.

[0058] Then, in step S103, the control device 22 issues a warning to the user of the wheeled vehicle and a notice to the passengers on the step connected body 13. That is, the control device 22 issues a warning to the user of the wheeled vehicle that boarding onto the step connected body 13 is prohibited by a plurality of notice devices.

[0059] In addition, the control device 22 causes the intermediate speaker 27c to generate an announcement instructing the user to hold onto the moving handrail 15 in order to decelerate the step connector 13.

[0060] Next, in step S104, the control device 22 decelerates the operating speed of the step connecting body 13. Then, in step S105, the control device 22 sets a timer t1 to 0.

[0061] Next, in step S106, the control device 22 determines whether the timer t1 is equal to or less than a first set time, for example, 30 seconds. If the timer t1 is not equal to or less than the first set time, that is, if the timer t1 exceeds the first set time, a process will be described later with reference to FIG.

[0062] If the timer t1 is equal to or less than the first set time, the control device 22 determines in step S107 whether or not the second detection signal has been input. If the second detection signal has not been input, the control device 22 adds Δt to the timer t1 in step S108, and returns to the process of step S106.

[0063] If the second detection signal is input within the first set time, the control device 22 registers the detection of the detection target tag 23 by the second detection device 25 in step S109.

[0064] Then, in step S110, the control device 22 issues a notice to passengers on the step connector 13. That is, the control device 22 makes an announcement from the middle speaker 27c instructing passengers to grab the moving handrail 15 in order to stop the step connector 13.

[0065] Thereafter, in step S111, the control device 22 stops the step connecting body 13 and ends the current monitoring process.

[0066] Fig. 4 is a flow chart showing the process when the second detection signal is not input within the first set time in the monitoring process of Fig. 3. After the wheeled vehicle is detected by the first detection device 24, if the user of the wheeled vehicle receives a warning and turns back, the process of Fig. 4 is executed.

[0067] If the second detection signal is not input within the first set time, the control device 22 sets a timer t2 to 0 in step S201.

[0068] Next, in step S202, the control device 22 determines whether the timer t2 is equal to or greater than a second set time, for example, 30 seconds.

[0069] If the timer t2 has not reached the second set time, the control device 22 determines in step S203 whether a new passenger on the step connector 13 has been detected by the lower passenger sensor 17 or the upper passenger sensor 18.

[0070] If a new passenger has not been detected, the control device 22 adds Δt to the timer t2 in step S204, and returns to the process of step S202.

[0071] If a new passenger is detected before the timer t2 reaches the second set time, the control device 22 returns to the process of step S201.

[0072] If the timer t2 reaches the second set time without detecting a new passenger, the control device 22 ends the warning to the user of the wheeled vehicle in step S205. Then, in step S206, the control device 22 returns the operating speed of the step connecting body 13 to the rated speed, and returns to the process of step S101 in FIG. 3.

[0073] Fig. 5 is a flow chart showing the abnormality detection process by the control device 22 of Fig. 2. The abnormality detection process is started when the detection of the detection target tag 23 by the second detection device 25 is registered.

[0074] When the abnormality detection process is started, in step S301, the control device 22 determines whether the detection of the detectable tag 23 by the first detection device 24 has been registered. If the detection by the first detection device 24 has been registered, the control device 22 ends the current abnormality detection process.

[0075] If detection by the second detecting device 25 has been registered but detection by the first detecting device 24 has not yet been registered, the control device 22 determines in step S302 that one of the first detecting devices 24 is abnormal.

[0076] Then, in step S303, the control device 22 notifies the outside, for example an escalator management center, of the abnormality in the first detection device 24, and ends this abnormality detection process.

[0077] In such an escalator monitoring and control system 21, a wheeled moving body is provided with a detectable tag 23. A first detection device 24 detects the detectable tag 23 in a non-contact manner and outputs a first detection signal. A second detection device 25 detects the detectable tag 23 in a non-contact manner and outputs a second detection signal.

[0078] Then, when the first detection signal is input, the control device 22 notifies the user of the wheeled mobile body that he / she is prohibited from getting on the step connecting body 13. Furthermore, when the second detection signal is input, the control device 22 stops the step connecting body 13.

[0079] This makes it possible to prevent the wheeled moving body from moving onto the step 13a. Even if the wheeled moving body does move onto the step 13a, the step connector 13 is stopped, so that damage to the equipment caused by the wheeled moving body getting on the step 13a can be more reliably prevented.

[0080] Furthermore, since the first detection device 24 and the second detection device 25 detect the target tag 23, complex processing such as image analysis is not required.

[0081] Furthermore, when the first detection signal is input, the control device 22 decelerates the step connecting body 13. Therefore, when the second detection signal is input to the control device 22, the step connecting body 13 can be stopped quickly, and even if the wheeled mobile body moves onto the step 13a, damage to the equipment can be more reliably suppressed.

[0082] Furthermore, when the second detection signal is not input within the first set time after the first detection signal is input, if no new users get on the step connector 13 for a second set time or more, the control device 22 returns the speed of the step connector 13 to the rated speed. Therefore, when the speed of the step connector 13 is returned to the rated speed, it is not necessary to alert passengers on the step connector 13.

[0083] Furthermore, when the second detection signal is input without the first detection signal being input, the control device 22 determines that an abnormality has occurred in the first detection device 24. For this reason, the abnormality in the first detection device 24 can be detected at an early stage.

[0084] Furthermore, the system can be simplified by using non-powered electronic components as the detection tag 23. Furthermore, the detection tag 23 can be made small and thin. Furthermore, the detection tag 23 can be reproduced in large quantities, making management easier.

[0085] Furthermore, by using a tag with a two-dimensional code as the detectable tag 23, the detectable tag 23 can be constructed more inexpensively than when a non-powered electronic component is used. Furthermore, detection of the two-dimensional code by a camera is excellent in immediacy, and the detectable tag 23 can be detected more reliably.

[0086] In addition, the second detection device 25 is disposed closer to the entrance / exit than the first detection device 24. Therefore, a wheeled moving body attempting to move onto the step connecting body 13 can be detected more reliably.

[0087] In addition, by attaching the detectable tag 23 to shopping carts 61 owned and managed by the commercial facility, the detectable tag 23 can be attached to the same position on many shopping carts 61, making it possible to detect the detectable tag 23 more reliably.

[0088] In addition, by using the detection tag 23 that can be attached to a wheeled vehicle, the detection tag 23 can be easily attached to a wheeled vehicle owned and managed by an individual. This makes it possible to prevent any wheeled vehicle from getting on the step connecting body 13.

[0089] The following describes the results of an investigation into the conditions for more reliably detecting the detection target tag 23 by the first detection device 24. The detection target tag 23 here is a non-powered electronic component. The first detection device 24 is a reader having an antenna. The conditions for more reliably detecting the detection target tag 23 also apply to the second detection device 25.

[0090] Fig. 6 is a front view showing a shopping cart 61 passing through the anti-theft gate 51 of Fig. 1. Fig. 7 is a front view showing a stroller 62 passing through the anti-theft gate 51 of Fig. 1.

[0091] The anti-theft gate 51 has a first support post 51a and a second support post 51b. A wheeled mobile object and a user pass through between the first support post 51a and the second support post 51b.

[0092] The first detection device 24 is provided on the first support pillar 51a. The first detection device 24 irradiates radio waves in the horizontal direction and can detect the target tag 23 within a detection range A indicated by a dashed line.

[0093] 6 and 7, in a case where the detectable tag 23 is arranged at a plurality of different positions, the detectable positions are indicated by ◯ and the undetectable positions are indicated by ×.

[0094] Condition 1: When the detection tag 23 passes through the anti-theft gate 51, the movement line of the detection tag 23 is sufficiently within the detection range A. This is because, due to the directional characteristics of the first detection device 24, there is a risk that the detection tag 23 cannot be detected near the boundary of the detection range A.

[0095] Condition 2: The first detection device 24 and the detection tag 23 are arranged facing each other. This is because detection accuracy is improved by having the substrate surface of the detection tag 23 facing the first detection device 24. For this reason, it is desirable that the detection tag 23 is attached to each of the side surfaces of the shopping cart 61 and the stroller 62.

[0096] Condition 3: The height of the first detection device 24 from the floor and the height of the detectable tag 23 from the floor are made as equal as possible. This is because if the installation position of the first detection device 24 is too high, it becomes difficult to place the detectable tag 23 within the detection range A.

[0097] Furthermore, if the installation position of the first detection device 24 is too low, there is a risk that the first detection device 24 or the detection target tag 23 may be damaged when the wheeled mobile body comes into contact with the anti-theft gate 51. Furthermore, if the installation position of the first detection device 24 is too low, the workability of maintenance of the first detection device 24 decreases.

[0098] From the above conditions 1 to 3, it is desirable to install the first detection device 24 at a height of, for example, 50 cm from the floor. In this case, it is desirable to attach the detection target tag 23 to the wheeled mobile body at a height of 50 cm to 80 cm from the floor.

[0099] It is also desirable to attach the detection tag 23 to the side of the front end of the wheeled vehicle, so that the wheeled vehicle can be detected quickly and accurately.

[0100] Fig. 8 is a front view showing a modified example of the installation state of the first detection device 24 relative to the anti-theft gate 51 of Fig. 7. Fig. 9 is a plan view showing the modified example of Fig. 8.

[0101] In this modified example, a first detection device 24 is installed on each of a first support pillar 51a and a second support pillar 51b. Accordingly, a detection target tag 23 is attached to both side surfaces of the wheeled mobile body.

[0102] If the first detection device 24 is installed only on the first support 51a, there is a risk that the detection tag 23 cannot be detected if there is an object that blocks radio waves between the first detection device 24 and the detection tag 23. In Figures 8 and 9, a child walking alongside a shopping cart 61 is shown as an example of the object. Another example of an object of obstruction is luggage sticking out from the platform of the shopping cart 61.

[0103] In contrast, as shown in Figures 8 and 9, if a first detection device 24 is installed on each of the first support pillar 51a and the second support pillar 51b, and a detectable tag 23 is attached to both side surfaces of the shopping cart 61, it is possible to prevent the detectable tag 23 from going undetected.

[0104] The first detection device 24 is not limited to the anti-theft gate 51, and may be provided, for example, on a photoelectric pole for detecting passengers or a partition belt. The partition belt is a belt that restricts the movement of escalator users.

[0105] Further, the second detection device 25 is not limited to being provided on the guide handrail 52, but may be provided on, for example, a balustrade panel, a building wall, or a door. The door may be a fire door.
