Description

The present invention relates to a passenger conveyor and a method for detecting passenger movement.

A passenger conveyor comprises a frame installed in a building structure, multiple steps connected endlessly within the frame that move in a circular motion, balustrades erected on both sides of the width of the multiple steps, and movable handrails movably supported on the balustrades. It is desirable for such passenger conveyors to prevent users from falling over while standing on the steps.

One of the reasons why users standing on steps may fall is when they move over multiple steps. For example, a user walking or running over multiple steps may trip over the unevenness of the steps and fall. It is also possible that a user moving over multiple steps may come into contact with another user standing on a step, causing at least one of the users to fall.

Patent Document 1 discloses scalator steps that restrict user movement on the steps. The steps disclosed in Patent Document 1 have a pressure sensor installed in a specific location, and an output unit that generates a warning output when the user's foot continuously steps on the specific location for a predetermined period of time. As a result, when the user walks while stepping on the specific location, a warning output is generated each time the user steps on the specific location.

JP 2012-166937 A

However, with the steps described in Patent Document 1, no warning output was generated when the user stepped on any part of the step other than a specific part. Therefore, if pressure sensors were installed on the entire surface of the steps, no warning output would be generated even if a user walked next to another user who was standing on the steps. As such, with the steps described in Patent Document 1, there were cases where the user's movement, such as walking or running, could not be detected.

In consideration of the above problems, the object of the present invention is to provide a passenger conveyor and a passenger movement detection method that can detect when passengers are moving on multiple steps.

In order to solve the above problems and achieve the object of the present invention, the passenger conveyor of the present invention comprises a plurality of circulating steps, balustrades arranged on both sides of the plurality of steps in the width direction, a position detection unit provided on the balustrades, a control unit , and an alarm unit . The position detection unit detects the positions of passengers on the plurality of steps. The control unit determines whether passengers are moving on the plurality of steps based on the detection results of the position detection unit. The alarm unit is capable of issuing warning alerts to call the attention of passengers on the plurality of steps.
The control unit calculates the passenger's moving speed per predetermined time based on the detection result of the position detection unit, and when the moving speed is outside a predetermined judgment range, determines that the passenger is moving on multiple steps, and when it determines that the passenger is moving on multiple steps, causes the alarm unit to issue a warning. Furthermore, the control unit compares the number of times that the moving speed is determined to be greater than the judgment range within a predetermined period with the number of times that it is determined to be less than the judgment range, and determines the content of the warning depending on the judgment that is greater.

In addition, in the passenger movement detection method of the present invention, position detection units provided on railings arranged on both sides of the plurality of steps in the width direction detect the positions of passengers on the plurality of steps. Next, a control unit calculates the passenger's movement speed per predetermined time based on the detection result of the position detection unit, and detects that the passenger is moving on the plurality of steps if the movement speed exceeds a predetermined judgment range. Then, when the control unit detects that the passenger is moving on the plurality of steps, it causes the alarm unit to issue a warning. Furthermore, the control unit compares the number of times that the movement speed is determined to be greater than the judgment range with the number of times that it is determined to be equal to or less than the judgment range within a predetermined period, and determines the content of the warning depending on the judgment that is the greater number of times.

According to the passenger conveyor and passenger movement detection method of the present invention, it is possible to detect that a passenger is moving on a plurality of steps.
Problems, configurations, and effects other than those described above will become clear from the following description of the embodiments.

1. One Embodiment A passenger conveyor according to one embodiment of the present invention will be described below with reference to Figures 1 to 4. Note that common members in each figure are denoted by the same reference numerals.

[Configuration of passenger conveyor]
First, the configuration of the passenger conveyor will be described with reference to FIG.
FIG. 1 is a schematic configuration diagram of a passenger conveyor according to one embodiment.

The passenger conveyor 1 shown in Figure 1 is an inclined passenger conveyor, commonly known as an escalator, installed on an upper floor 100 and a lower floor 101 of an architectural structure (building). The passenger conveyor 1 comprises a frame 2 installed on the architectural structure, a plurality of steps 3, a balustrade 4, a drive unit 6, and a control unit 7. Furthermore, the passenger conveyor 1 comprises an upper boarding/alighting floor 8, a lower boarding/alighting floor 9, and an alarm unit 10.

Frame 2 is installed across the upper floor 100 and the lower floor 101. The end of frame 2 facing the upper floor 100 is installed on the upper floor via an upper support beam 11. The end of frame 2 facing the lower floor 101 is installed on the lower floor via a lower support beam 12. Frame 2 is composed of an inclined section, an upper horizontal section, and a lower horizontal section. Hereinafter, the direction extending from the lower floor 101 toward the upper floor 100 of frame 2 will be referred to as the longitudinal direction of frame 2. The direction perpendicular to the longitudinal direction of frame 2 and perpendicular to the vertical direction will be referred to as the width direction of frame 2.

The upper horizontal section is formed on the upper floor 100 side in the longitudinal direction of the frame 2. A machine room 14 is provided in the upper horizontal section. The upper part of the machine room 14 is enclosed by the upper boarding floor 8. The drive unit 6 and control unit 7 are installed in the machine room 14.

The lower horizontal section is formed on the lower floor 101 side of the frame 2 in the longitudinal direction. A lower pit 15 is provided in the lower horizontal section. The upper part of the lower pit 15 is closed by the lower boarding and alighting floor 9. The inclined section of the frame 2 is formed between the upper horizontal section and the lower horizontal section, and is inclined relative to the horizontal direction.

In the passenger conveyor 1, the machine room 14, in which the drive unit 6 and control unit 7 are installed, is installed in the upper horizontal section of the frame 2, but this is not limited to this. The machine room of the present invention may also be installed, for example, in the lower horizontal section of the frame 2 or in the inclined section in the middle of the frame 2.

An upper sprocket (not shown) is located in the upper horizontal section of frame 2. The upper sprocket is located closer to the inclined section of frame 2 than the drive unit 6. A lower sprocket (not shown) is located in the lower horizontal section of frame 2. The lower sprocket is located closer to the inclined section of frame 2 than the lower pit 15.

An endless step chain (not shown) is wound around the upper and lower sprockets. The drive unit 6 is rotated by the upper sprocket. When the upper sprocket rotates, the lower sprocket rotates via the step chain. As a result, the step chain moves cyclically between the upper and lower sprockets.

A number of steps 3 are endlessly connected to the step chain. The steps 3 are movably supported on a guide rail unit (not shown) attached to the frame 2. The steps 3 then move in a circular motion between the upper and lower sprockets along the guide rail unit. The steps 3 also reverse their direction of movement at the upper and lower sprockets.

The balustrade 4 is supported on the top of the frame 2. The balustrade 4 is arranged on both sides of the frame 2 in the width direction. A handrail 5 is movably supported on the periphery of the balustrade 4. The handrail 5 moves in a circular motion in synchronization with the circular movement of the multiple steps 3.

A signal detection unit 17 is attached to one of the balustrades 4 arranged on both sides of the frame 2 in the width direction. The signal detection unit 17 corresponds to the position detection unit of the present invention. The signal detection unit 17 extends along the direction of movement of the multiple steps 3. The signal detection unit 17 is, for example, a leaky coaxial cable. The signal detection unit 17 is connected to the control unit 7 via a wire or wirelessly.

The signal detection unit 17 receives radio waves output from the mobile terminal. Therefore, the signal detection unit 17 can detect the position of the passenger via the mobile terminal 200 (see Figure 2) carried by the passenger. The signal detection unit 17 receives (detects) radio waves output from the mobile terminal 200 from the time the passenger gets on the passenger conveyor until they get off. The signal detection unit 17 then transmits the detection results to the control unit 7.

The alarm unit 10 is provided in the upper horizontal section of the frame 2. The alarm unit 10 is a device capable of issuing warning alerts to alert passengers on the multiple steps 3. The alarm unit 10 can be, for example, a speaker that outputs sound, a light that outputs light, or a display device that displays video or images. The alarm unit 10 is not limited to being provided in the upper horizontal section of the frame 2, and its location can be set appropriately depending on the device used.

If a speaker is used as the alarm unit 10, the alarm will output a sound to alert passengers on the multiple steps 3. If a light is used as the alarm unit 10, the alarm will output a light to alert passengers on the multiple steps 3. If a display unit is used as the alarm unit 10, the alarm will display a video or image to alert passengers on the multiple steps 3. The alarm unit of the present invention may be a combination of two or more devices, such as a speaker and a display device.

[Configuration of control unit]
Next, the internal configuration of the control unit 7 will be described with reference to FIG.
FIG. 2 is a block diagram showing an example of the internal configuration of the control unit 7.

The control unit 7 includes a signal receiving unit 21, a recording unit 22, a time counter 23, and a calculation unit 24.

The signal receiving unit 21 receives the detection results (detection signals) transmitted from the signal detecting unit 17. The signal receiving unit 21 then converts the received detection signals into passenger position information (passenger position information) and transmits it to the recording unit 22 and the calculation unit 24.

The recording unit 22 records the received passenger position information and the time of reception. The time information is supplied from the time counter 23. The recording unit 22 also records the judgment range set to determine whether a passenger is moving on multiple steps 3. The judgment range will be explained later.

The time counter 23 counts the time during which passenger location information is received.

The calculation unit 24 calculates the passenger's movement speed based on the passenger position information converted by the signal receiving unit 21 and the reception time. The calculation unit 24 calculates the passenger's movement speed at each predetermined time (unit time). If the calculated passenger's movement speed exceeds the judgment range, the calculation unit 24 determines that the passenger's movement speed is abnormal.

If the abnormality in the passenger's movement speed continues for a certain period of time, the calculation unit 24 determines that the passenger is moving on multiple steps 3. This makes it clear that the passenger has been moving on multiple steps 3 for a certain period of time. Furthermore, even if the passenger is standing on a step 3 and there is a slight sway or movement, it can be prevented from being determined that the passenger is moving on multiple steps 3.

The fixed period can be set as appropriate, but it may be set, for example, to about half the time it would take for a passenger to stand still on the step 3 from the time they board the passenger conveyor until they disembark.

When the calculation unit 24 determines that a passenger is moving on multiple steps 3, it controls the notification unit 10 to issue a warning alert to alert passengers on the multiple steps 3. The calculation unit 24 also controls the drive unit 6 to cause the multiple steps 3 to move in a circular motion or to stop the circular movement of the multiple steps 3.

The judgment range is set according to the speed of circular movement of the multiple steps 3. The speed of movement of a passenger standing on a step 3 is approximately the same as the speed of circular movement of the multiple steps 3. Therefore, the judgment range is set to a range that includes the speed of circular movement of the multiple steps 3. For example, if the passenger conveyor can set the speed of circular movement of the multiple steps 3 to a normal speed or a high speed that is faster than the normal speed, a judgment range corresponding to the normal speed and a judgment speed corresponding to the high speed are set.

If the calculated passenger movement speed is greater than the judgment range, it can be determined that the passenger is walking, running, or falling in the direction of movement of the multiple steps 3. On the other hand, if the calculated passenger movement speed is less than the judgment range, it can be determined that the passenger is walking, running (running backwards), or falling in the opposite direction to the movement of the multiple steps 3.

The calculation unit 24 may also determine the passenger's status, such as walking, running, or falling, based on the calculated passenger movement speed and the calculated acceleration. The content of the warning issued by the notification unit 10 may be changed depending on the passenger's movement direction and status. This allows for more detailed warnings to be given to passengers. Furthermore, if it is determined that a passenger has fallen down multiple steps 3, the operation of the passenger conveyor 1 may be stopped.

The calculation unit 24 also determines whether passengers are moving on the multiple steps 3 in a predetermined section within the movement section of the multiple steps 3. The predetermined section is set to a section excluding a specific section where passengers get on and off the multiple steps 3. In other words, the predetermined section is set between a first specific section where passengers get on the steps 3 and a second specific section where passengers get off the steps 3. Furthermore, the time required for each step 3 to enter and exit the predetermined section is equal to or longer than the above-mentioned certain period.

When passengers board and disembark on multiple steps 3, there is a tendency for differences to occur between the passenger's moving speed and the moving speed of the steps 3. As a result, in specific sections where passengers board and disembark on multiple steps 3, the control unit 7 may erroneously determine that the passenger is moving on multiple steps 3. Therefore, the passenger conveyor of this embodiment prevents erroneous determinations by determining whether or not a passenger is moving on multiple steps 3 in a specified section.

[Configuration of the computer that constitutes the control unit]
Next, the hardware configuration of the computer that constitutes the control unit 7 of the passenger conveyor 1 will be described.
FIG. 3 is a block diagram showing an example of the hardware configuration of the computer that constitutes the control unit 7.

As shown in FIG. 3, the computer 30 that constitutes the control unit 7 is hardware used as a computer. The computer 30 includes a CPU (Central Processing Unit) 31, a ROM (Read Only Memory) 32, a RAM (Random Access Memory) 33, non-volatile storage 35, and a network interface 36, all of which are connected to a bus 34.

The CPU 31 reads from the ROM 32 and executes the program code of the software that realizes each function of this embodiment. Variables, parameters, etc. generated during the calculation process are temporarily written to the RAM 33. The CPU 31 executes the program code corresponding to the calculation unit 24 recorded in the ROM 32, thereby realizing the functions of the calculation unit 24. The calculation unit 24 running on the CPU 31 can then calculate the passenger's movement speed, determine whether the movement speed is normal or above normal, and determine whether the passenger is moving on multiple steps 3.

The non-volatile storage 35 may be, for example, a hard disk drive (HDD), a solid state drive (SSD), a flexible disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, magnetic tape, or non-volatile memory. This non-volatile storage 35 stores the operating system (OS), various parameters, and programs for running the computer 30.

ROM 32 and non-volatile storage 35 store programs and data necessary for CPU 31 to operate, and are used as examples of computer-readable, non-transitory storage media that store programs executed by calculator 30. For this reason, this program is permanently stored in ROM 32 and non-volatile storage 35. The recording unit 22 shown in Figure 2 is configured, for example, in non-volatile storage 35, and records passenger position information, reception time, determination range, etc.

The network interface 36 may be, for example, a network interface card (NIC). The network interface 36 can transmit and receive various data between devices via a local area network (LAN) or dedicated line to which its terminals are connected. The network interface 36 is used, for example, in the signal receiving unit 21. The network interface 36 is also provided between the calculation unit 24 and the drive unit 6 and notification unit 10.

[Passenger movement detection processing]
Next, the passenger movement detection process performed by the control unit 7 will be described with reference to FIG.
FIG. 4 is a flowchart showing an example of passenger movement detection processing according to this embodiment.

First, the control unit 7 determines whether or not it has received a detection signal transmitted from the signal detection unit 17 (S1). If it determines in step S1 that it has not received a detection signal (if S1 returns a NO determination), the control unit 7 repeats step S1. That is, the control unit 7 repeats step S1 until it receives a detection signal.

When it is determined in step S1 that a detection signal has been received (if S1 returns a YES result), the control unit 7 converts the detection signal into passenger position information (S2).

Next, the control unit 7 determines whether the passenger corresponding to the passenger position information is in a predetermined section among the movement sections of the multiple steps 3 (S3). If it is determined in step S3 that the passenger corresponding to the passenger position information is not in the predetermined section (if S3 is determined to be NO), the control unit 7 returns the processing to step S1.

In step S3, when it is determined that a passenger corresponding to the passenger location information is in a specified section (if S3 returns a YES result), the control unit 7 determines whether the detection signal detected in the specified section has started counting the reception time (S4).

If it is determined in step S4 that the detection signal detected in the specified interval does not indicate that the reception time has started to be counted (if S4 returns a NO judgment), the control unit 7 starts counting the reception time using the time counter 23 (S5). After processing step S5, the control unit 7 returns the process to step S1.

In step S4, when it is determined that the detection signal detected in the specified section has started counting the reception time (if S4 returns a YES result), the control unit 7 calculates the passenger's movement speed when a specified time (unit time) has elapsed (S6).

In step S6, if the passenger's movement speed is being calculated for the first time, the distance traveled by the passenger (mobile terminal 200) from the start of counting the reception time until a predetermined time has elapsed is calculated to calculate the passenger's movement speed. If the passenger's movement speed is being calculated for the second or subsequent time, the distance traveled by the passenger (mobile terminal 200) from the previous calculation of the movement speed until a predetermined time has elapsed is calculated to calculate the passenger's movement speed.

Next, the control unit 7 determines whether the passenger's movement speed is within a preset determination range (S7). If it is determined in step S7 that the passenger's movement speed is within the determination range (YES in S7), the control unit 7 returns the process to step S1.

If it is determined in step S7 that the passenger's movement speed is not within the determination range (if S7 is a NO determination), the control unit 7 determines whether the determination that the passenger's movement speed is not within the determination range has continued until a certain period of time has passed (S8). If it is determined in step S8 that the determination has not continued until a certain period of time has passed (if S8 is a NO determination), the control unit 7 returns the process to step S1.

If it is determined in step S8 that the reception has continued for a certain period of time (if S8 returns a YES determination), the control unit 7 determines whether the passenger's moving speed is greater than the determination range (S9). The control unit 7 also terminates counting the reception time using the time counter 23.

When it is determined in step S9 that the passenger's movement speed is greater than the determination range (if S9 returns a YES result), the control unit 7 causes the notification unit 10 to issue a warning (S10). After processing step S10, the control unit 7 terminates the passenger movement detection process.

If the passenger's moving speed is greater than the judgment range, it can be determined that the passenger is walking or running in the same direction as the moving direction of the multiple steps 3. Therefore, the warning issued in step S10 alerts the passenger that they are walking or running in the moving direction of the multiple steps 3.

If it is determined in step S9 that the passenger's movement speed is not greater than the determination range (if S9 returns a NO), the control unit 7 causes the notification unit 10 to issue a warning (S11). After processing step S11, the control unit 7 terminates the passenger movement detection process.

If the passenger's moving speed is not greater than the judgment range, it can be determined that the passenger is walking or running in the opposite direction to the direction of travel of the multiple steps 3. Therefore, the warning issued in step S11 alerts the passenger that they are walking or running in the opposite direction to the direction of travel of the multiple steps 3.

In the passenger movement detection process according to this embodiment, in step S9, it is determined whether the passenger movement speed calculated immediately before is greater than the judgment range. However, the passenger movement detection process according to the present invention may also compare the number of times that the passenger movement speed is determined to be greater than the judgment range over a certain period of time with the number of times that the passenger movement speed is determined to be less than the judgment range, and determine the content of the warning based on the greater number of determinations.

2. Summary As described above, the passenger conveyor 1 according to the embodiment described above includes a plurality of steps 3 that move in a circular manner, balustrades 4 arranged on both sides of the steps 3 in the width direction, a signal detection unit 17 (position detection unit) that is provided on the balustrade 4 and detects the position of passengers on the steps 3, and a control unit 7. The control unit 7 determines whether or not passengers are moving on the steps 3 based on the detection results of the signal detection unit 17.
This makes it possible to detect that a passenger is moving on a plurality of steps 3. Furthermore, there is no need to install a position detection unit in the building, and the signal detection unit 17 can be installed simply by installing the balustrade 4.

Furthermore, the passenger conveyor 1 according to the embodiment described above includes a notification unit 10 capable of issuing a warning to call the attention of passengers on the plurality of steps 3. When the control unit 7 determines that passengers are moving on the plurality of steps 3, it causes the notification unit 10 to issue a warning.
This prevents passengers from moving over multiple steps 3.

In addition, the signal detection unit 17 (position detection unit) according to the embodiment described above extends along the direction of movement of the multiple steps 3, receives radio waves output from the mobile terminal 200 carried by the passenger, and detects the position of the passenger on the multiple steps 3.
This allows the position of the passenger to be detected with a simple configuration.

In addition, the control unit 7 according to the embodiment described above calculates the passenger's movement speed per specified time based on the detection results of the signal detection unit 17 (position detection unit), and determines that the passenger is moving on multiple steps 3 if the movement speed remains outside a predetermined judgment range for a certain period of time that is longer than the specified time.
This makes it possible to grasp the moving speed of the passenger and reliably detect that the passenger is moving on multiple steps 3. It is also possible to detect that the passenger is continuously moving on multiple steps 3 until a certain period of time has passed. Furthermore, even if the passenger sways or moves slightly on a step 3 where he or she is standing, it is possible to prevent the passenger from being determined to be moving on multiple steps 3.

In addition, in the passenger conveyor of the present invention, the control unit 7 may calculate the passenger's movement speed per specified time based on the detection results of the signal detection unit 17 (position detection unit), and determine that the passenger is moving on multiple steps 3 if the movement speed is outside a predetermined determination range. In this case, too, the passenger's movement speed can be determined, and it can be reliably detected that the passenger is moving on multiple steps 3. Furthermore, it can be determined that the passenger has moved on multiple steps 3 earlier than if the determination is made after a certain period of time has continued.

In addition, the control unit 7 according to the embodiment described above determines whether passengers are moving on the multiple steps 3 in a predetermined section excluding a specific section where passengers get on and off the multiple steps 3.
This makes it possible to avoid determining whether or not a passenger is moving on the multiple steps 3 in a specific section where there is a tendency for a difference to occur between the moving speed of the passenger and the moving speed of the multiple steps 3. As a result, it is possible to prevent erroneous determination of whether or not a passenger is moving on the multiple steps 3.

Furthermore, the passenger conveyor 1 according to the embodiment described above includes a notification unit 10 capable of issuing a warning to call the attention of passengers on the plurality of steps 3. The control unit 7 causes the notification unit 10 to issue a warning when it is determined that a passenger is moving on the plurality of steps 3. The control unit 7 then differentiates the content of the warning when the moving speed is higher than the determination range from that when the moving speed is lower than the determination range.
This allows a warning to be issued according to the direction of movement of the passenger, and as a result, passengers can be effectively prevented from moving on multiple steps 3.

In the passenger movement detection method according to the embodiment described above, first, the signal detection units 17 (position detection units) provided on the balustrades 4 arranged on both sides of the steps 3 in the width direction detect the positions of passengers on the steps 3. Next, the control unit 7 calculates the moving speed of the passenger per predetermined time based on the detection results of the signal detection units 17. Then, the control unit 7 detects that the passenger is moving on the steps 3 when the calculated moving speed exceeds a predetermined determination range.
This makes it possible to detect passengers moving on the multiple steps 3. Furthermore, there is no need to install a signal detection unit (position detection unit) in the building; the signal detection unit 17 can be installed simply by installing the balustrade 4.

The above describes embodiments of the passenger conveyor and passenger movement detection method of the present invention, including their effects. However, the passenger conveyor and passenger movement detection method of the present invention are not limited to the above-described embodiments, and various modifications are possible within the scope of the invention as set forth in the claims.

For example, in the above-described embodiment, the control unit 7 is configured to determine whether passengers are moving on multiple steps 3 in a specified section. However, the passenger conveyor of the present invention may also determine whether passengers are moving on multiple steps 3 in a specific section of the moving section of multiple steps 3 where passengers get on and off the multiple steps 3.

In addition, in the above-described embodiment, a leaky coaxial cable that receives radio waves from a mobile terminal is used as the position detection unit. However, the position detection unit of the present invention is not limited to a leaky coaxial cable. For example, the position detection unit of the present invention may be multiple photoelectric sensors each consisting of a light-emitting unit that emits light and a light-receiving unit that receives light. In this case, the light-emitting units of the multiple photoelectric sensors are attached to one railing, and the light-receiving units of the multiple photoelectric sensors are attached to the other railing. In addition, an infrared sensor may be used as the position detection unit of the present invention.

In the above-described embodiment, an escalator with steps between it has been used as an example of an inclined passenger conveyor. However, the passenger conveyor of the present invention can also be applied to a motorized roadway with multiple steps without steps between them, a so-called moving walkway. When the present invention is applied to a motorized roadway, it detects if a passenger is moving in the opposite direction to the movement of the multiple steps.
