Description

The present disclosure relates to a control device for a passenger conveyor.

In conventional passenger conveyors, if a passenger is continuously detected at the entrance for a first period of time, the circulation speed of the steps is then lowered than the normal circulation speed for a second period of time. Therefore, if a passenger is hesitant to board the passenger conveyor, the circulation speed of the steps is reduced (for example, Patent Document 1).

Japanese Patent Application Publication No. 2007-153539

However, with conventional passenger conveyors, even when the passenger conveyor is crowded and passengers waiting at the entrance to maintain distance from passengers who have boarded the passenger conveyor earlier, the steps are not recirculated. There was a problem that the speed could be lowered.

The present disclosure has been made to solve the above-mentioned problems, and provides a passenger conveyor control device that can more appropriately control the moving speed of a conveyor according to the condition of passengers at the entrance. The purpose is to obtain.

A control device for a passenger conveyor according to the present disclosure includes a control device main body that controls the moving speed of a conveyance body that conveys passengers based on information from a passenger sensor that detects passengers at a boarding entrance. When the time during which the detection state continues is defined as the detection time, and the time during which the non-detection state of the passenger continues by the passenger sensor is defined as the non-detection time, the control device main body detects the non-detection time after the non-detection time becomes equal to or longer than the first reference time. When the detection time exceeds the second reference time, the moving speed is reduced.

According to the passenger conveyor control device according to the present disclosure, the moving speed of the conveyor can be more appropriately controlled depending on the condition of the passengers at the entrance.

Hereinafter, embodiments will be described with reference to the drawings.
Embodiment 1.
FIG. 1 is a configuration diagram showing a passenger conveyor control device according to a first embodiment together with main parts of the passenger conveyor. The passenger conveyor has a main frame 1, a conveyor 2, and a pair of handrails 3. The main frame 1 is installed between the building beams on the upper and lower floors.

The carrier 2 is supported by the main frame 1. Further, the transport body 2 transports passengers by circulating. Further, the transport body 2 is configured by connecting a plurality of steps 2a in an endless manner. In FIG. 1, only three steps 2a are shown. In FIG. 1, passengers are transported from the lower floor to the upper floor, as indicated by the arrows. Thus, in this embodiment, the passenger conveyor is operated in the upward direction.

A pair of parapets 3 are erected on the main frame 1. Further, the pair of balustrades 3 are arranged at intervals in the width direction of the main frame 1. The width direction of the main frame 1 is horizontal and perpendicular to the passenger transport direction. Further, each of the pair of balustrades 3 has a skirt guard 4. Each skirt guard 4 is provided at the lower part of the corresponding parapet 3. In FIG. 1, only one of the pair of balustrades 3 is shown.

The upper surfaces of the left and right ends of the main frame 1 serve as entrances for the passenger conveyor. Of the two entrances, the entrance on the lower floor of the main frame 1 is the entrance 5. Of the two entrances, the entrance on the upper floor of the main frame 1 is the exit 6.

The passenger conveyor control device includes a control device main body 7 and a passenger sensor 8. The control device main body 7 is provided inside the main frame 1 on the upper floor. The passenger sensor 8 is provided on the skirt guard 4 on the lower floor. The control device main body 7 and the passenger sensor 8 are electrically connected to each other.

The control device main body 7 controls the moving speed of the carrier 2 based on information from the passenger sensor 8 .

FIG. 2 is a top view of the boarding entrance 5 with no passengers present. FIG. 3 is a top view of the boarding entrance 5 where passengers are present. A floorboard 9 is provided at the entrance 5.

Passenger sensor 8 is a transmission type photoelectric sensor. The passenger sensor 8 has a light projector 8a and a light receiver 8b. The light projector 8a is provided on one skirt guard 4, and the light receiver 8b is provided on the other skirt guard 4.

The light projector 8a and the light receiver 8b are provided at a distance of 200 mm to 300 mm from the boundary between the carrier 2 and the entrance 5 in a direction parallel to the X-axis shown in FIG. Furthermore, the light emitter 8a and the light receiver 8b are provided 150 mm to 200 mm above the surface of the floorboard 9 in the height direction, that is, in the direction parallel to the Z axis. Further, the light projector 8a and the light receiver 8b face each other so that the light receiver 8b can receive the light from the light projector 8a. Note that the numerical values regarding the position where the passenger sensor 8 is provided are merely examples, and the present invention is not limited to these numerical values.

By arranging the passenger sensor 8 in this manner, the passenger sensor 8 detects a passenger at the entrance 5. The optical axis 10 of the light beam emitted from the projector 8a is parallel to the Y-axis. As shown in FIG. 2, when there are no passengers at the entrance 5, the light receiver 8b can receive light from the light projector 8a. In this case, since no passenger is detected, the state of the passenger sensor 8 becomes a "non-detection state".

On the other hand, as shown in FIG. 3, when a passenger 11 is present at the entrance 5, the light from the projector 8a is blocked by the passenger 11. Therefore, the light receiver 8b becomes unable to receive light from the light projector 8a. In this case, since the passenger 11 is detected, the state of the passenger sensor 8 becomes the "detection state".

When the passenger 11 gets on the passenger conveyor, the light receiver 8b becomes able to receive light from the light projector 8a, so the state of the passenger sensor 8 changes from the "detection state" to the "non-detection state". Note that even if another passenger passes the passenger 11 in the "detection state", the detection result by the passenger sensor 8 does not change.

FIG. 4 is a first example of a time chart showing the relationship between the state of the passenger sensor 8 and the moving speed of the carrier 2. In FIG. FIG. 5 is a second example of a time chart showing the relationship between the state of the passenger sensor 8 and the moving speed of the carrier 2. In FIG. FIG. 6 is a third example of a time chart showing the relationship between the state of the passenger sensor 8 and the moving speed of the carrier 2. The period shown in FIGS. 4-6 includes the period in which two passengers board the passenger conveyor at a time interval.

As shown in FIG. 4, in the first example, the time between time t1 and time t2 is the first detection time Tdt by the passenger sensor 8. The detection time Tdt is the time during which the passenger sensor 8 continues to detect a passenger. The first detection time Tdt is less than the second reference time Ts2.

The time between time t2 and time t5 after the first detection time Tdt is a non-detection time Tnd. The non-detection time Tnd is the time during which the passenger sensor 8 continues to be in a non-detection state of the passenger. The non-detection time Tnd is longer than the first reference time Ts1.

The time between time t5 and time t6 is the second detection time Tdt by the passenger sensor 8. The second detection time Tdt is less than or equal to the second reference time Ts2.

The first reference time Ts1 is set to, for example, 1 second. The moving speed of the carrier 2 is set to 30 m/min as a normal speed V1 during normal times. When the conveyance body 2 is moving at the normal speed V1, the conveyance body 2 moves by 1.25 steps during the first reference time Ts1.

When the non-detection time Tnd is equal to or longer than the first reference time Ts1, the interval between the detection states before and after the non-detection state is sufficiently secured, so it is imagined that passengers board the passenger conveyor one after another.

If the non-detection time Tnd is less than the first reference time Ts1, the interval between the detection states before and after the non-detection state is not sufficiently secured, and when a passenger gets on the passenger conveyor, there is a gap between the passenger in front and the passenger in front. There is a possibility of stopping at entrance 5 to vacate the area.

The second reference time Ts2 is set to, for example, 4 seconds. When the carrier 2 is moving at the normal speed V1, the carrier 2 moves five steps during the second reference time Ts2. When the detection time Tdt is less than the second reference time Ts2, the control device main body 7 does not change the moving speed of the carrier 2, as shown in FIG. 4. That is, the control device main body 7 maintains the moving speed of the carrier 2 at the normal speed V1.

As shown in FIG. 5, in the second example, the first detection time Tdt is less than the second reference time Ts2. The non-detection time Tnd after the first detection time Tdt is longer than the first reference time Ts1. Further, the second detection time Tdt is longer than the second reference time Ts2.

When the detection time Tdt becomes the second reference time Ts2 after the non-detection time Tnd becomes equal to or greater than the first reference time Ts1, the control device main body 7 starts moving at time t7 when the second reference time Ts2 has elapsed. The speed is reduced from the normal speed V1. At time t8, when the deceleration time Tdec has elapsed from time t7, the moving speed reaches the auxiliary speed V2. The control device main body 7 maintains the moving speed at the auxiliary speed V2 after time t8.

The auxiliary speed V2 is a speed for assisting the passenger 11 to get onto the passenger conveyor. The auxiliary speed V2 is set to a speed lower than the normal speed V1. For example, the auxiliary speed V2 is set to 20 m/min. After time t8, the control device main body 7 maintains the moving speed at the auxiliary speed V2.

In this way, if the non-detection time Tnd is secured for the first reference time Ts1 or longer and the passenger 11 is considered to have remained at the boarding gate 5 for the second reference time Ts2 or longer, the passenger 11 is prevented from boarding the passenger conveyor. It is assumed that they are hesitant. Therefore, the control device main body 7 reduces the moving speed from the normal speed V1 to the auxiliary speed V2.

As shown in FIG. 6, in the third example, the first detection time Tdt is less than the second reference time Ts2. The non-detection time Tnd after the first detection time Tdt is less than the first reference time Ts1. Further, the second detection time Tdt is longer than the third reference time Ts3.

When the detection time Tdt becomes the third reference time Ts3 after the non-detection time Tnd becomes less than the first reference time Ts1, the control device main body 7 starts moving at time t7 when the third reference time Ts3 has elapsed. The speed is reduced from the normal speed V1. The third reference time Ts3 is longer than the second reference time Ts2. At time t8, when the deceleration time Tdec has elapsed from time t7, the moving speed reaches the auxiliary speed V2. The control device main body 7 maintains the moving speed at the auxiliary speed V2 after time t8.

In this way, even if the non-detection time Tnd is not secured for the first reference time Ts1 or longer, if the passenger 11 is considered to have remained at the boarding gate 5 for the third reference time Ts3 or longer, the passenger 11 It is assumed that the person is hesitant to get onto the conveyor. Therefore, the control device main body 7 reduces the moving speed from the normal speed V1 to the auxiliary speed V2.

In other words, in this case, the third reference time Ts3 is set to be longer than the second reference time Ts2, since it is assumed that the passenger 11 stops to create space between him and the preceding passenger. Further, in this case, the control device main body 7 maintains the moving speed of the carrier 2 at the normal speed V1 of 30 m/min. The third reference time Ts3 is set to, for example, 8 seconds. When the conveyance body 2 is moving at the normal speed V1, the conveyance body 2 moves by 10 steps during the third reference time Ts3.

FIG. 7 is a flowchart showing a "moving speed control routine when a passenger to be decelerated gets on the passenger conveyor" executed by the control device main body 7 of FIG. 1. When the routine of FIG. 7 is started, the control device main body 7 sets the moving speed of the carrier 2 to the normal speed V1 in step S101. Next, the control device main body 7 measures the non-detection time Tnd in step S102.

Next, in step S103, the control device main body 7 determines whether the passenger sensor 8 is in the detection state. When the state of the passenger sensor 8 is not in the detection state, that is, in the non-detection state, the control device main body 7 measures the non-detection time Tnd again in step S102. That is, the control device main body 7 continues measuring the non-detection time Tnd.

The measurement of the non-detection time Tnd is repeated until the state of the passenger sensor 8 becomes the detection state. On the other hand, when the state of the passenger sensor 8 is in the detection state, the control device main body 7 determines in step S104 whether the non-detection time Tnd is equal to or longer than the first reference time Ts1.

If the non-detection time Tnd is greater than or equal to the first reference time Ts1, the control device main body 7 determines in step S105 whether the detection time Tdt is greater than or equal to the second reference time Ts2.

If the detection time Tdt is greater than or equal to the second reference time Ts2, the control device main body 7 measures the non-detection time Tnd again in step S102. On the other hand, if the detection time Tdt is equal to or longer than the second reference time Ts2, the control device main body 7 reduces the moving speed of the carrier 2 in step S106.

Further, if it is determined in step S104 that the non-detection time Tnd is less than the first reference time Ts1, the control device main body 7 determines in step S107 whether the detection time Tdt is greater than or equal to the third reference time Ts3. Determine.

If the detection time Tdt is less than the third reference time, the control device main body 7 measures the non-detection time Tnd again in step S102. On the other hand, if the detection time Tdt is equal to or longer than the third reference time Ts3, the control device main body 7 reduces the moving speed of the carrier 2 in step S106.

FIG. 8 is a fourth example of a time chart showing the relationship between the state of the passenger sensor 8 and the moving speed of the carrier 2. In FIG. As shown in FIG. 8, in the fourth example, the first detection time Tdt is less than the second reference time Ts2. Further, the non-detection time Tnd after the first detection time Tdt is longer than the first reference time Ts1. Further, the second detection time Tdt is longer than the second reference time Ts2.

As shown in FIG. 8, the control device main body 7 reduces the moving speed of the transport body 2 toward the auxiliary speed V2 at time t7. Thereafter, the control device main body 7 directs the moving speed of the carrier 2 to the normal speed V1 at a time t9 when the elapsed time from time t6, which is the end of the second detection time Tdt, reaches the fourth reference time Ts4. increase. Time t6 is the time when passenger 11 is considered to have boarded the passenger conveyor. That is, after the passenger 11 gets on the passenger conveyor, the control device main body 7 restores the moving speed of the carrier 2 to the normal speed V1.

The fourth reference time Ts4 is set to, for example, 3 seconds. When the conveyance body 2 is moving at the auxiliary speed V2, the conveyance body 2 moves by 2.5 steps during the fourth reference time Ts4.

Further, the control device main body 7 calculates the estimated arrival time Taes based on the moving speed of the carrier 2 and the set position. The estimated arrival time Taes is an estimated value of the time required for the deceleration target passenger to reach the set position. The set position is a position in front of the exit 6. The deceleration target passenger is a passenger whose moving speed of the carrier 2 is to be reduced. Then, the control device main body 7 again reduces the moving speed of the carrier 2 from the normal speed V1 to the auxiliary speed V2 at time t10 based on the calculated estimated arrival time Taes.

Further, the control device main body 7 calculates the estimated boarding time Tres based on the moving speed of the carrier 2 and the length of the passenger conveyor. The estimated boarding time Tres is an estimated value of the time that the passenger to be decelerated is on the passenger conveyor, that is, an estimated value of the time until the passenger to be decelerated gets off the passenger conveyor. Then, the control device main body 7 increases the moving speed of the carrier 2 again from the auxiliary speed V2 to the normal speed V1 at time t11 based on the calculated estimated boarding time Tres.

FIG. 9 is a flowchart showing the "moving speed control routine while the passenger to be decelerated is on the passenger conveyor" executed by the control device main body 7 of FIG. 1. When the routine of FIG. 9 is started, in step S201, the control device main body 7 measures the time from the end of the detection time Tdt, that is, from time t6 when the state of the passenger sensor 8 becomes "non-detection state". do. The control device main body 7 increases the moving speed of the carrier 2 toward the normal speed V1 at time t9 when the fourth reference time Ts4 has elapsed from time t6. The control device main body 7 continues to measure the elapsed time even after the moving speed of the carrier 2 reaches the normal speed V1.

Next, in step S202, the control device main body 7 calculates an estimated arrival time Taes based on the moving speed and set position of the carrier 2, and when the estimated arrival time Taes has elapsed, the moving speed of the carrier 2 is calculated. is decreased toward the auxiliary speed V2.

Next, in step S203, the control device main body 7 calculates the estimated boarding time Tres based on the moving speed of the transport object 2 and the length of the passenger conveyor, and when the estimated boarding time Tres has elapsed, the control device main body 7 calculates the estimated boarding time Tres of the transport object 2. Increase the movement speed toward normal speed V1.

In addition, when it becomes necessary to reduce the moving speed of the carrier 2 for another passenger after the passenger to be decelerated gets on the passenger conveyor, the control device main body 7 controls the moving speed of the carrier 2 for another passenger. be controlled in the same way.

As described above, the passenger conveyor control device according to the first embodiment includes the control device main body 7. The control device main body 7 controls the moving speed of the carrier 2 based on information from the passenger sensor 8 . A passenger sensor 8 detects a passenger 11 at the entrance 5. The transport body 2 transports passengers 11.

The control device main body 7 reduces the moving speed when the detection time Tdt reaches the second reference time Ts2 subsequent to the non-detection time Tnd becoming equal to or longer than the first reference time Ts1. The detection time Tdt is the time during which the passenger sensor 8 continues to detect the passenger 11. The non-detection time Tnd is a period of time during which the passenger sensor 8 continues to non-detect the passenger 11.

According to this, the interval between the passenger who boarded the passenger conveyor first and the passenger who is about to board the passenger conveyor is longer than the first reference time Ts1. Therefore, it is difficult to imagine that a passenger who is about to board the passenger conveyor will wait at the entrance 5 to create space between him and the passenger who has boarded the passenger conveyor first. Therefore, if the detection time Tdt becomes the second reference time Ts2 after the non-detection time Tnd becomes equal to or greater than the first reference time Ts1, it is assumed that the passenger is hesitant to board the passenger conveyor. Ru.

In other words, when it is assumed that the passenger is hesitant to get on the passenger conveyor, the moving speed of the carrier 2 can be reduced to assist the passenger in getting on the passenger conveyor. Therefore, the moving speed of the carrier 2 can be controlled more appropriately depending on the condition of the passengers at the entrance 5.

Further, the control device main body 7 reduces the moving speed when the detection time Tdt reaches the third reference time Ts3 following the non-detection time Tnd becoming less than the first reference time Ts1. The third reference time Ts3 is longer than the second reference time Ts2.

According to this, since the non-detection time Tnd is less than the first reference time Ts1, a passenger who is about to board the passenger conveyor must wait at the boarding gate 5 in order to leave a space between him and the passenger who has boarded the passenger conveyor first. It is also expected that you will have to wait. Therefore, in this case, in order to distinguish between the passengers who are waiting at the entrance 5 to keep a space between them and the passengers who have boarded the passenger conveyor first, and the passengers who are hesitant to board the passenger conveyor, the third The reference time Ts3 is set to be longer than the second reference time Ts2.

In other words, according to this, it is possible to distinguish between passengers who are waiting at the entrance 5 to space themselves from passengers who have boarded the passenger conveyor first, and passengers who are hesitant to board the passenger conveyor. can.

Further, in the passenger conveyor control device according to the first embodiment, the control device main body 7 controls the conveyor body 7 when the elapsed time from the end of the detection time Tdt reaches the fourth reference time Ts4 after reducing the moving speed. Increases movement speed of 2.

If the moving speed of the carrier 2 is reduced in order to assist passengers to board the passenger conveyor, the conveyance efficiency of the passenger conveyor will be reduced. According to this, since the time during which the moving speed of the conveyor 2 is reduced is limited, a decrease in the conveyance efficiency of the passenger conveyor is suppressed.

The control device main body 7 also calculates the estimated arrival time Taes, and reduces the moving speed again based on the estimated arrival time Taes. The estimated arrival time Taes is an estimated value of the time required for the deceleration target passenger to reach the set position in front of the exit 6. The deceleration target passenger is a passenger whose travel speed is to be reduced.

According to this, when the passenger to be decelerated gets off the passenger conveyor, the moving speed of the carrier 2 is lowered, so that it is possible to assist the passenger to be decelerated to get off the passenger conveyor.

The passenger conveyor control device further includes a transmission type photoelectric sensor as the passenger sensor 8.

The transmission type photoelectric sensor detects a passenger when the light from the light projector 8a is blocked by the passenger and the light receiver 8b can no longer receive the light from the light projector 8a. Therefore, even if another passenger passes you while the transmissive photoelectric sensor is detecting a passenger, the detection results of the transmissive photoelectric sensor are unlikely to be influenced by the other passengers. Therefore, according to this, passengers who are hesitant to board the passenger conveyor can be detected more reliably.

In the present embodiment, after the passenger to be decelerated gets on the passenger conveyor, the control device main body 7 restores the moving speed of the carrier 2 from the auxiliary speed V2 to the normal speed V1. However, the control device main body 7 may maintain the moving speed of the carrier 2 at the auxiliary speed V2 from the time the passenger to be decelerated gets on the passenger conveyor until the passenger gets off the passenger conveyor.

The difference between the fourth reference time Ts4 and the estimated arrival time Taes changes depending on the length of the passenger conveyor, the moving speed of the carrier 2, the fourth reference time Ts4, and the set position. Therefore, for example, if the difference between the fourth reference time Ts4 and the estimated arrival time Taes is smaller than the predetermined determination time, the control device main body 7 will control the deceleration target passenger from the time the passenger gets on the passenger conveyor until the passenger gets off the passenger conveyor. The moving speed of the carrier 2 may be maintained at the auxiliary speed V2.

Further, in the present embodiment, after the passenger to be decelerated gets on the passenger conveyor, the control device main body 7 recovers the moving speed of the carrier 2 to the normal speed V1, but the moving speed at the time of recovery is as follows. The speed does not necessarily have to be equal to the normal speed V1. The movement speed during recovery may be higher than the auxiliary speed V2 within a range that does not exceed the normal speed V1.

Further, in the present embodiment, when the passenger to be decelerated gets off the passenger conveyor, the control device main body 7 reduces the moving speed of the conveyor 2 to the auxiliary speed V2, but the moving speed in this case is not necessarily The speed does not have to be equal to the auxiliary speed V2. Furthermore, the control device main body 7 does not need to reduce the moving speed of the conveyor 2 when the passenger to be decelerated gets off the passenger conveyor.

In addition, in the present embodiment, a value for the first reference time Ts1, a value for the second reference time Ts2, a value for the third reference time Ts3, a value for the fourth reference time Ts4, and a value for the number of steps. are merely examples, and are not limited to these numerical values. Further, the numerical values for the normal speed V1 and the numerical values for the auxiliary speed V2 are merely examples, and the present invention is not limited to these numerical values.

In addition, the control device main body 7 calculates the estimated arrival time, but instead calculates the distance traveled by the passenger to be decelerated based on the measured elapsed time and the moving speed of the carrier 2, and decelerates. When the target passenger reaches the set distance, the moving speed of the carrier 2 may be reduced toward the auxiliary speed V2.

In addition, the control device main body 7 calculates the estimated boarding time, but instead calculates the distance traveled by the passenger to be decelerated based on the measured elapsed time and the moving speed of the carrier 2, and decelerates. After the target passenger reaches the exit 6, the moving speed of the carrier 2 may be restored to the normal speed V1.

Further, although a transmission type photoelectric sensor has been used as a passenger sensor, the passenger sensor is not limited to this. A photoelectric sensor other than a transmission type, for example, a reflection type photoelectric sensor may be used as the passenger sensor. Further, the passenger sensor may be a sensor other than a photoelectric sensor. For example, a radar, a LiDAR (Light Detection And Ranging) scanner, an ultrasonic sensor, or a camera may be used as the passenger sensor.

Further, although the control device main body 7 and the passenger sensor 8 are electrically connected, the control device main body 7 and the passenger sensor 8 may be connected by wireless communication.

Further, the location where the control device main body 7 is installed is not limited to inside the main frame 1 on the upper floor.

Further, in the present embodiment, the escalator is operated in the upward direction, but the escalator is not limited to this, and may be operated in the downward direction. When the escalator is operated in the down direction, the passenger sensor 8 is provided on the skirt guard 4 on the upper floor.

Further, in the case of an escalator in which the circulation direction of the carrier can be switched, the passenger sensor 8 is provided on the skirt guard 4 on each of the upper and lower floors.

Further, the passenger sensor 8 does not necessarily need to be provided on the skirt guard 4, but may be provided at a position where it can detect a passenger who is about to get on the passenger conveyor.

Further, the passenger conveyor is not limited to an escalator, and may be a moving walkway, for example. Furthermore, the moving walkway may be horizontal or inclined. Further, the conveyor may be of a belt conveyor type.

Further, the functions of the passenger conveyor control device of the first embodiment are realized by a processing circuit. FIG. 10 is a configuration diagram showing a first example of a processing circuit that implements the functions of the passenger conveyor control device according to the first embodiment. Processing circuit 100 in the first example is dedicated hardware.

The processing circuit 100 may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof. Applicable.

Further, FIG. 11 is a configuration diagram showing a second example of a processing circuit that realizes the functions of the passenger conveyor control device of the first embodiment. The processing circuit 200 of the second example includes a processor 201 and a memory 202.

In the processing circuit 200, the functions of the passenger conveyor control device are realized by software, firmware, or a combination of software and firmware. Software and firmware are written as programs and stored in memory 202. The processor 201 implements functions by reading and executing programs stored in the memory 202.
