Description

[Technical field]

[0001] SUMMARY OF THE DISCLOSURE An embodiment of the present invention relates to a passenger conveyor system. [Background technology]

[0002] Generally, passenger conveyors (e.g., escalators, moving walkways, etc.) have a structure that allows them to be used as stairs or walkways even when the conveyor is stopped, so even if the conveyor is stopped, it does not necessarily mean that there are no passengers (users) on the conveyor. If the conveyor is started and begins to operate while there are passengers on the conveyor, there is a possibility of accidents such as falls occurring. For this reason, when starting or stopping the conveyor, the manager of the facility where the conveyor is installed (hereinafter referred to as the "facility manager") must visually confirm on-site that there are no passengers on the conveyor before starting or stopping the conveyor.

[0003] Incidentally, in elevators, automatic diagnostic operation is performed to collect information (operation information) showing the status of various devices that compose the elevator. However, as described above, passenger conveyors require the presence of a facility manager when starting and stopping the passenger conveyors, so in reality, it is difficult to perform automatic diagnostic operation like that of elevators.

[0005] An object of the present invention is to provide a passenger conveyor system that is capable of starting a passenger conveyor and diagnosing the condition of the passenger conveyor without the presence of a facility manager. [Means for solving the problem]

[0006] A passenger conveyor system according to one embodiment diagnoses a state of the passenger conveyor. The passenger conveyor system includes a control device that controls the operation of the passenger conveyor, and a detection device that is installed near a boarding and disembarking section of the passenger conveyor and detects a user on the passenger conveyor. The control device includes a storage unit that stores time information indicating a start time for starting the passenger conveyor, a determination unit that continuously determines whether or not a user is on the passenger conveyor based on a detection result from the detection device after the start time indicated by the time information, and an information processing unit that starts the passenger conveyor, operates the passenger conveyor in a first operation mode, and diagnoses the state of the passenger conveyor when a result of the determination made by the determination unit at the start time indicates that no user is on the passenger conveyor. When the result of the judgment made by the judgment unit when the diagnosis in the first operation mode is completed indicates that there is no user on the passenger conveyor, the information processing unit operates the passenger conveyor in a second operation mode having a faster moving speed than the first operation mode, and further diagnoses the condition of the passenger conveyor, and when the result of the judgment made by the judgment unit when the diagnosis in the second operation mode is completed indicates that there is no user on the passenger conveyor, the information processing unit operates the passenger conveyor in a third operation mode having a faster moving speed than the second operation mode, and further diagnoses the condition of the passenger conveyor.

[0008] Hereinafter, an embodiment will be described with reference to the drawings. In addition, the disclosure is merely an example, and the invention is not limited to the contents described in the following embodiments. Modifications that a person skilled in the art can easily conceive are naturally included in the scope of the disclosure. In order to make the explanation clearer, the size, shape, etc. of each part may be changed from the actual embodiment and shown diagrammatically. In multiple drawings, corresponding elements may be given the same reference numerals, and detailed explanations may be omitted.

[0009] In the following, a case will be described in which the passenger conveyor included in the passenger conveyor system is an "escalator."

[0010] FIG. 1 is a diagram showing an example of a schematic configuration of a passenger conveyor system according to this embodiment. The passenger conveyor system includes an escalator 10, and is a system capable of diagnosing the state of various devices constituting the escalator 10 (a system capable of collecting operation information of various devices constituting the escalator 10). As shown in FIG. 1, the escalator 10 is installed at an angle between a lower floor and an upper floor of a building, for example. Note that the example shown in FIG. 1 assumes that the lower floor side is the entrance to the escalator 10, and the upper floor side is the exit to the escalator 10.

[0011] The escalator 10 shown in FIG. 1 is configured to transport passengers (users) on the steps 11 by circulating the steps 11, which are connected without any gaps, between a lower machine room 12 (entrance) and an upper machine room 13 (exit).

[0012] The steps 11 are connected by an endless connecting chain 14 and are arranged inside a truss 15 installed under the floor of the building. A lower sprocket 16 and an upper sprocket 17 are arranged inside the truss 15, and the connecting chain 14 is wound between them.

[0013] In the example shown in Fig. 1, a driving device 18 having a motor, a reducer, etc. is connected to the upper sprocket 17. The driving device 18 rotates the lower sprocket 16 and the upper sprocket 17 around which the connecting chain 14 is wound, and the steps 11 move cyclically between the lower machine room 12 and the upper machine room 13 via the connecting chain 14 while being guided by a guide rail (not shown). Although the driving device 18 is connected to the upper sprocket 17 in Fig. 1, the driving device 18 may be connected to the lower sprocket 16.

[0014] In addition, a pair of skirt guards (not shown) are installed on the upper part of the truss 15 along the moving direction of the steps 11 so as to face both side surfaces of each step 11. A balustrade 19 is erected on the upper part of each pair of skirt guards. In other words, the balustrades 19 are erected on both sides of each step 11. A belt-like handrail 20 is attached around the balustrade 19. The handrail 20 is a handrail that is held by passengers on the steps 11, and rotates in synchronization with the movement of the steps 11 by transmitting the driving force of the drive unit 18, for example.

[0015] The entrances (boarding entrance and exit entrance) of escalator 10 are located at the top of lower machine room 12 and upper machine room 13, and boarding and alighting plates 22 and 23 are removably installed at the entrances. Boarding and alighting plates 22 and 23 correspond to the ceilings of lower machine room 12 and upper machine room 13. Passengers pass over boarding and alighting plate 22 when getting on escalator 10 (steps 11), and pass over boarding and alighting plate 23 when getting off escalator 10 (steps 11).

[0016] In addition to the driving device 18, a control device 21 is installed in the upper machine room 13. The control device 21 controls the operation of various devices (e.g., the operation of the driving device 18) installed on the escalator 10 in order to control the operation of the escalator 10.

[0017] The detection device 24 is, for example, an infrared beam sensor including a projector 24a and a receiver 24b, and the projector 24a and the receiver 24b are installed near the boarding and disembarking area so as to face each other. For example, the projector 24a is installed on a deck cover near the boarding entrance with an irradiation port that irradiates an infrared beam facing the disembarking entrance (facing the receiver 24b side), and the receiver 24b is installed on a deck cover near the disembarking entrance with a light receiving surface that receives the infrared beam facing the boarding entrance (facing the projector 24a side).

[0018] The remote monitoring device 25 is installed near the control device 21 and is connected by wire to the control device 21. The remote monitoring device 25 is also connected to a monitoring center (not shown) so as to be able to communicate with it.

[0019] The remote monitoring device 25 transmits to the monitoring center information indicating the status of various devices constituting the escalator 10 obtained from the control device 21 (diagnosis result information, which will be described in detail later) and information indicating the operating status of the escalator 10. In addition, the remote monitoring device 25 receives various instructions (e.g., diagnosis instructions) from the monitoring center and outputs the received various instructions to the control device 21.

[0020] 2 is a block diagram showing an example of a functional configuration of some elements included in the passenger conveyor system according to the present embodiment. As shown in FIG. 2, the control device 21 is connected to both the detection device 24 and the remote monitoring device 25.

[0021] As shown in FIG. 2, the control device 21 includes a storage unit 21a, a user presence determination unit 21b, an information processing unit 21c, and an operation control unit 21d.

[0022] The storage unit 21a stores start time information indicating the start time (operation start time) of the escalator 10. The storage unit 21a may further store stop time information indicating the stop time (operation end time) of the escalator 10. The storage unit 21a may also store operation schedule information including the start time information and the stop time information.

[0023] User presence determination unit 21b continuously (repeatedly) determines whether or not a user is present on escalator 10 based on the detection result acquired from detection device 24 after the start-up time of escalator 10 indicated by the start-up time information stored in storage unit 21a. Note that, as an example here, detection device 24 is assumed to switch from off to on when the start-up time of escalator 10 is reached and to start irradiating an infrared beam from projector 24a to receiver 24b, but is not limited thereto, and detection device 24 may be one that constantly irradiates an infrared beam from projector 24a to receiver 24b. Also, detection device 24 may be switched from on to off when, for example, a series of processes shown in FIG. 3 described later is completed.

[0024] When the result of the determination made by user presence determination unit 21b at the start time indicates that there is no user on escalator 10, information processing unit 21c starts escalator 10 and outputs an instruction to operation control unit 21d to set the operation mode of escalator 10 to a low-speed operation mode (first operation mode). When operation control unit 21d receives an instruction to set the operation mode of escalator 10 to the low-speed operation mode from information processing unit 21c, it controls the operation of drive device 18 so as to operate escalator 10 at a low speed. The low-speed operation mode is an operation mode in which escalator 10 is operated at a moving speed of, for example, 10 m / min.

[0025] If the result of the determination made by the user presence determination unit 21b when low-speed operation is started indicates that there is no user on the escalator 10, the information processing unit 21c performs diagnosis of various devices that constitute the escalator 10 while operating the escalator 10 in low-speed operation mode.

[0026] Furthermore, when the result of the determination made by user presence determination unit 21b upon completion of the diagnosis in the low-speed operation mode indicates that there is no user on escalator 10, information processing unit 21c outputs an instruction to operation control unit 21d to switch the operation mode of escalator 10 from the low-speed operation mode to the energy-saving operation mode (second operation mode). When operation control unit 21d receives an instruction from information processing unit 21c to switch the operation mode of escalator 10 from the low-speed operation mode to the energy-saving operation mode, it controls the operation of drive device 18 so as to operate escalator 10 in an energy-saving manner. The energy-saving operation mode is an operation mode in which escalator 10 is operated at a moving speed of, for example, 20 m / min.

[0027] When the result of the determination made by the user presence determination unit 21b when energy saving operation is started indicates that there is no user on the escalator 10, the information processing unit 21c performs diagnosis of various devices that constitute the escalator 10 while operating the escalator 10 in the energy saving operation mode.

[0028] Furthermore, when the result of the determination made by user presence determination unit 21b upon completion of the diagnosis in the energy saving operation mode indicates that there is no user on escalator 10, information processing unit 21c outputs an instruction to operation control unit 21d to switch the operation mode of escalator 10 from the energy saving operation mode to the normal operation mode (third operation mode). When operation control unit 21d receives an instruction from information processing unit 21c to switch the operation mode of escalator 10 from the energy saving operation mode to the normal operation mode, it controls the operation of drive device 18 to operate escalator 10 normally. The normal operation mode is an operation mode in which escalator 10 is operated at a moving speed of, for example, 30 m / min.

[0029] When the result of the determination made by the user presence determination unit 21b when normal operation is started indicates that there is no user on the escalator 10, the information processing unit 21c performs diagnosis of various devices that constitute the escalator 10 while operating the escalator 10 in normal operation mode.

[0030] Diagnostic result information indicating the results of the diagnoses performed in the low-speed operation mode, the energy-saving operation mode, and the normal operation mode is stored in the memory unit 21a and transmitted to a monitoring center (not shown) via the remote monitoring device 25.

[0031] In addition, if the result of the determination made by the user presence determination unit 21b at the start time indicates that a user is on the escalator 10, the information processing unit 21c will not start the escalator 10 because there is a risk of the user falling.

[0032] Furthermore, when the escalator 10 starts to operate in each operation mode or when the diagnosis in each operation mode is completed, if the result of the determination made by the user presence determination unit 21b indicates that a user is on the escalator 10, the information processing unit 21c outputs an instruction to the operation control unit 21d to switch the operation mode of the escalator 10 to the normal operation mode. In this case, the information processing unit 21c transmits, to the monitoring center via the remote monitoring device 25, diagnostic result information indicating that the diagnosis of the various devices constituting the escalator 10 has failed. Alternatively, the information processing unit 21c transmits, to the monitoring center via the remote monitoring device 25, diagnostic result information indicating the result of the diagnosis performed before it was determined that a user is on the escalator 10, among the diagnoses performed in each operation mode.

[0033] 2, the remote monitoring device 25 includes a communication unit 25a and a control unit 25b. The communication unit 25a is a communication interface for communicating with the control device 21 and the monitoring center. The control unit 25b controls the operation of the remote monitoring device 25.

[0034] FIG. 3 is a flowchart showing an example of the operation of the passenger conveyor system according to this embodiment. When the start-up time indicated by the start-up time information stored in the memory unit 21a arrives (step S1), the user presence determination unit 21b determines whether or not a user is present on the escalator 10 based on the detection result obtained from the detection device 24 at this timing (step S2).

[0035] As a result of the determination in step S2, when it is determined that a user is on the escalator 10 (Yes in step S2), the information processing unit 21c does not start the escalator 10, and executes the above-mentioned process of step S2 again.

[0036] On the other hand, if it is determined in step S2 that there is no user on escalator 10 (No in step S2), information processing unit 21c starts escalator 10 and outputs an instruction to operation control unit 21d to set the operation mode of escalator 10 to the low-speed operation mode (first operation mode). In accordance with the above-mentioned instruction from information processing unit 21c, operation control unit 21d controls the operation of drive device 18 so as to operate escalator 10 at low speed (step S3).

[0037] When the escalator 10 starts to operate in the low-speed operation mode, the user presence determining unit 21b determines whether or not a user is present on the escalator 10 based on the detection result acquired from the detection device 24 at this timing (step S4).

[0038] If it is determined in step S4 that a user is present on escalator 10 (Yes in step S4), information processing unit 21c outputs an instruction to operation control unit 21d to switch the operation mode of escalator 10 to the normal operation mode. Operation control unit 21d controls the operation of drive device 18 so as to operate escalator 10 normally in accordance with the above-mentioned instruction from information processing unit 21c (step S5). Thereafter, information processing unit 21c transmits diagnosis result information indicating that the diagnosis of various devices constituting escalator 10 has failed to the monitoring center via remote monitoring device 25 (i.e., notifies the monitoring center of the failure of the diagnosis) (step S6), and ends the series of operations here.

[0039] On the other hand, if the result of the judgment in step S4 is that there is no user on the escalator 10 (No in step S4), the information processing unit 21c performs diagnosis of various devices that make up the escalator 10 while operating the escalator 10 in a low-speed operating mode (step S7).

[0040] When the diagnosis in the low-speed operation mode is completed, the user presence determining unit 21b determines whether or not a user is present on the escalator 10 based on the detection result acquired from the detection device 24 at this timing (step S8).

[0041] As a result of the determination in step S8, if it is determined that a user is on the escalator 10 (Yes in step S8), the processes in steps S5 and S6 described above are executed in order.

[0042] On the other hand, if it is determined in step S8 that there is no user on escalator 10 (No in step S8), information processing unit 21c outputs an instruction to operation control unit 21d to switch the operation mode of escalator 10 from the low-speed operation mode to the energy-saving operation mode (second operation mode). In accordance with the above-mentioned instruction from information processing unit 21c, operation control unit 21d controls the operation of drive device 18 so as to operate escalator 10 in energy-saving mode (step S9).

[0043] When the escalator 10 starts to operate in the energy saving operation mode, the user presence determining unit 21b determines whether or not a user is present on the escalator 10 based on the detection result acquired from the detection device 24 at this timing (step S10).

[0044] As a result of the determination in step S10, if it is determined that a user is on the escalator 10 (Yes in step S10), the processes in steps S5 and S6 described above are executed in order.

[0045] On the other hand, if the result of the judgment in step S10 is that there is no user on the escalator 10 (No in step S10), the information processing unit 21c performs diagnosis of various devices that make up the escalator 10 while operating the escalator 10 in an energy-saving operation mode (step S11).

[0046] When the diagnosis in the energy saving operation mode is completed, the user presence determining unit 21b determines whether or not a user is present on the escalator 10 based on the detection result acquired from the detection device 24 at this timing (step S12).

[0047] As a result of the determination in step S12, if it is determined that a user is on the escalator 10 (Yes in step S12), the processes in steps S5 and S6 described above are executed in order.

[0048] On the other hand, if it is determined in step S12 that there is no user on escalator 10 (No in step S12), information processing unit 21c outputs an instruction to operation control unit 21d to switch the operation mode of escalator 10 from the energy saving operation mode to the normal operation mode (third operation mode). In accordance with the above instruction from information processing unit 21c, operation control unit 21d controls the operation of drive device 18 so as to operate escalator 10 in the normal mode (step S13).

[0049] When the escalator 10 starts to operate in the normal operation mode, the user presence determining unit 21b determines whether or not a user is present on the escalator 10 based on the detection result acquired from the detection device 24 at this timing (step S14).

[0050] As a result of the determination in step S14, if it is determined that a user is on the escalator 10 (Yes in step S14), the processes in steps S5 and S6 described above are executed in order.

[0051] On the other hand, if the result of the judgment in step S14 is that there is no user on the escalator 10 (No in step S14), the information processing unit 21c performs diagnosis of various devices that make up the escalator 10 while operating the escalator 10 in normal operation mode (step S15).

[0052] Thereafter, the information processing unit 21c transmits (notifies) the diagnosis result information indicating the results of the diagnoses performed in each operating mode to the monitoring center via the remote monitoring device 25 (step S16), and terminates the series of operations here.

[0053] As described above, the passenger conveyor system according to this embodiment, when it arrives at the start time indicated by the start time information pre-stored in memory unit 21a, determines whether or not a user is present on escalator 10 based on the detection result acquired from detection device 24 at that start time, and starts escalator 10 if it is determined that no user is present. In this way, since escalator 10 can be started safely and automatically, it is no longer necessary for a facility manager to go to the site to start escalator 10, and it is possible to reduce the burden on the facility manager.

[0054] Furthermore, when the escalator 10 is started, the passenger conveyor system according to this embodiment operates the escalator 10 in a low-speed operation mode, an energy-saving operation mode, and a normal operation mode, each of which has a different moving speed, in that order, and diagnoses various devices constituting the escalator 10. This allows automatic diagnosis of the escalator 10 every time the escalator 10 is started, making it possible to find any abnormality that may occur in the escalator 10 at an early stage. Furthermore, since maintenance personnel can perform regular inspection work based on the results of the automatic diagnosis performed every time the escalator 10 is started, it is also possible to expect a reduction in the number of work steps during regular inspection (i.e., a reduction in the burden on maintenance personnel during regular inspection work).

[0055] In this embodiment, the case where the escalator 10 is started safely and automatically has been described, but the escalator 10 can also be stopped safely and automatically by carrying out the same process as when the escalator 10 is started (i.e., by executing the processes of steps S1 and S2 shown in FIG. 3). This makes it possible to reduce the burden on the facility manager not only when the escalator 10 is started, but also when the escalator 10 is stopped.

[0056] Furthermore, in the present embodiment, the diagnosis of the various devices constituting the escalator 10 is performed when the escalator 10 is started up, but the present invention is not limited to this, and the diagnosis of the various devices constituting the escalator 10 may be performed, for example, when the escalator 10 is stopped. In this case, the information processing unit 21c can perform diagnosis in each operation mode by transitioning the operation mode of the escalator 10, for example, through the normal operation mode, the energy saving operation mode, and the low-speed operation mode in that order.

[0057] Furthermore, the diagnosis of the various devices constituting the escalator 10 may be performed not only when the escalator 10 is started or stopped, but also when the operation mode is switched during operation.

[0058] In this embodiment, the case where the detection device 24 is an infrared beam sensor has been described, but the present invention is not limited to this, and the detection device 24 may be any device that can detect the presence of a user on the escalator 10. For example, the detection device 24 may be a camera that is attached to a sensor pole and can capture images of the top of the escalator 10.

[0059] In addition, in the present embodiment, a case has been described in which the passenger conveyor included in the passenger conveyor system is the escalator 10, but this is not limited thereto, and the passenger conveyor included in the passenger conveyor system may be, for example, a "moving walkway."

[0060] According to the embodiment described above, it is possible to provide a passenger conveyor system that is capable of starting a passenger conveyor and diagnosing the state of the passenger conveyor without the presence of a facility manager.

[0061] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, and are included in the scope of the invention and its equivalents described in the claims.
