Description

  The present invention relates to a passenger conveyor control device having a function of controlling a moving speed of a tread according to a walking state of a passenger in a passenger conveyor such as an escalator device.

  A conventional escalator is provided with a passenger movement speed detection device, calculation means, a drive unit that drives a step having a step board on which the passenger rides, and a control device. The passenger movement speed detection device is installed in the vicinity of the entrance / exit of the escalator device. Then, the moving speed of the passenger before getting into the escalator device is detected by the passenger moving speed detecting device, and the moving speed of the step corresponding to the detected moving speed of the passenger is set by the calculation means. The set moving speed of the step is instructed to the driving machine through the control device, and the speed of the driven step is accelerated or decelerated.

  The calculation means issues a low speed command for moving the step below the rated speed when the measured movement speed of the passenger is lower than the standard passenger movement speed, which is a standard walking speed of a normal healthy person. Thus, the movement speed of the escalator tread has been controlled so as to be the optimum tread board movement speed that can contribute to the prevention of a fall accident even for persons with reduced walking ability (see, for example, Patent Document 1).

JP 2004-99266 A

  However, the conventional escalator detects the walking speed of the passenger in the moving direction of the tread, and controls the moving speed of the tread according to the detection result. For example, if a deaf person who is walking at the standard walking speed of a normal healthy person gets on an escalator while rolling with respect to the moving direction of the tread, the treadle will move at the rated speed. There is a risk that it will not be possible to respond to the moving speed of the tread and it will not be easy to get on the tread.

FIG. 4 is a block diagram for explaining the configuration of the analysis control unit of the passenger conveyor control device, and FIG. 4 is a diagram for explaining how the analysis control unit of the passenger conveyor control device according to the first embodiment determines the walking state of the passenger. 4A is a plan view in which a passenger's image captured by the camera is a still image, and FIG. 4B is a first view from the shooting time of FIG. 4A. FIG. 4 (c) is a plan view in which FIG. 4 (a) and FIG. 4 (b) are superimposed, and FIG. Flow for explaining the operation of the passenger conveyor control device according to the first embodiment It is.

  1 and 2, the passenger conveyor control device 1 includes an escalator device 2 as a passenger conveyor device, a camera 3, an analysis control unit 4, and a speaker 20 as a notification means.

The main configuration of the escalator device 2 will be described.
In the escalator device 2, an upper floor side sprocket 11 a and a lower floor side sprocket 11 b are arranged on the upper floor side and the lower floor side in the escalator body 6, respectively.
Although not shown in detail, the escalator body 6 is formed into a hollow body by a frame called a truss that is a framework of the escalator device 2 and an outer plate attached to this side surface.
Further, an endless step chain 5 is provided so as to be able to run over the upper floor side sprocket 11a and the lower floor side sprocket 11b.

  On the step chain 5, a large number of steps 9 mainly composed of a step plate 7 and a riser 8 corresponding to the raising of the staircase are continuously hooked and arranged in an endless conveyor form. On the upper floor side of the escalator body 6, there is provided a driving device 10 such as a motor that rotates the step 9 together with the step chain 5 via the upper floor side sprocket 11 a. The steps 9 are rotated in a direction to carry passengers from the upper floor side to the lower floor side, for example, at a speed of 30 m / min.

Moreover, the balustrade 12 is erected above the escalator main body 6 so as to sandwich both sides in the moving direction of the steps 9 arranged like a conveyor. In addition, an endless moving handrail 13 is disposed on the upper part of the balustrade 12, and the drive device 10 travels in synchronization with the steps 9.
Further, an escalator control panel 14 as a passenger conveyor control panel that controls the travel of the escalator device 2 is disposed in the escalator body 6 in the vicinity of the driving device 10.

  The camera 3 is disposed on the ceiling facing the step board 7 on the entrance side of the escalator device 2, and the lens of the camera 3 is further directed toward the entrance so that the periphery of the entrance can be photographed from obliquely above. Yes.

As shown in FIG. 3, the analysis control unit 4 is electrically connected to the camera 3, the speaker 20, and the escalator control panel 14 by wires 15 a to 15 c, respectively. The video taken by the camera 3 is sent to the analysis control unit 4.
The analysis control unit 4 includes a ROM 16 as a first storage unit that stores a control program of the passenger conveyor control device 1, a communication unit 17, and a second storage unit for storing video data captured by the camera 3. As a RAM 18 or a hard disk (HD) and a CPU 19 as a calculation control means incorporating a plurality of timers.

The communication unit 17 is an interface that mediates communication between the analysis control unit 4 and the camera 3, the speaker 20, and the escalator control panel 14.
The analysis control unit 4 analyzes the image data stored in the RAM 18, transmits the data to the escalator control panel 14, and controls the speaker 20 connected via the communication means 17, so that an arbitrary announcement is made to the speaker 20. Can be made.

  The escalator control panel 14 can control the escalator device 2 based on the data received from the analysis control unit 4.

The ROM 16 further stores a first image acquisition interval time, a normal walking determination value, a tread board speed setting value, a passing time, and an image scale value.
The first image acquisition interval time is used to determine the acquisition interval time of still image data of video captured by the camera 3. For example, if the first image acquisition interval time is set to 0.5 seconds, still images near the entrance every 0.5 seconds are stored in the RAM 18 continuously. When the data size of the image stored in the RAM 18 exceeds the capacity of the RAM 18, the old one is overwritten sequentially.

  As will be described later, the normal walking determination value is used to determine whether or not the walking state of the passenger is abnormal. For example, 15 cm is stored as a set value.

  In addition, as the tread board speed setting value, a normal driving speed and a slow driving speed are set. The normal driving speed is set according to the normal walking speed of a healthy person, for example, 30 m / min. The slow operation speed is set to a speed lower than the normal operation speed, and is set to 20 m / min, for example. Then, as will be described later, the normal driving speed or the slow driving speed is sent to the escalator control panel 14 in accordance with the determination result of the walking state of the passengers by the CPU 19, and the escalator control panel 14 moves the step 9, that is, the moving speed of the tread plate 7. Is controlled so that the normal operation speed or the slow operation speed is transmitted.

  In addition, when the operation of the escalator device 2 is started by the administrator of the passenger conveyor control device 1, the passenger conveyor control device 1 sends the normal operation speed data from the analysis control unit 4 to the escalator control panel 14. Is set to

  As for the passing time, the step board 7 travels and travels the distance from the entrance to the exit of the escalator device 2 during a time when the passenger can reach the tread board 7 with sufficient margin after the passenger is detected by the analysis control unit 4. The time it takes is added. Therefore, after the passenger who uses the escalator device 2 is displayed on the image of the camera 3, a value more than the time required for the passenger to get on the tread board 7 on the upper floor and get off on the lower floor is the passing time. Is set.

  The image scale value is a scale value with respect to the actual size of the still image acquired by the camera 3 in the vertical axis direction and the horizontal axis direction. The CPU 19 refers to the image scale value and calculates the actual size from the acquired distance on the still image.

  Next, a control operation of the analysis control unit 4 and a method for determining the walking state of the passenger will be described with reference to FIG.

  Video data captured by the camera 3 is constantly sent to the analysis control unit 4. Then, the CPU 19 of the analysis control unit 4 stores the video data in the RAM 18 as a still image every set first image acquisition interval time (0.5 seconds). Further, the CPU 19 analyzes the superimposed images of the still and previous still images stored in the RAM 18 at every first image acquisition interval time. When there is a change in the superimposed image, the CPU 19 determines that the passenger is projected on the video sent from the camera 3.

When the CPU 19 determines that the passenger has been projected on the camera 3, the CPU 19 further analyzes the superimposed images of the still images before and after the passenger is completely reflected on the camera 3 to determine the walking state of the passenger.
For example, FIG. 4A is a still image in which a haunted passenger walking toward the tread 7 while swinging his / her body in the lateral direction with respect to the traveling direction is reflected. 4B is a still image acquired after the first image acquisition interval time has elapsed after the still image acquisition of FIG. 4A.

  Then, the passenger's walking state is analyzed by analyzing the superimposed image shown in FIG. 4C in which the still image shown in FIG. 4A and the still image shown in FIG. Is judged. In the image analysis under the control of the CPU 19, for example, in the superimposed image shown in FIG. 4C, the passenger's head is analyzed, and the passenger walks by shaking the head in the lateral direction with respect to the traveling direction. Is detected as a moving distance L1 in the still image. Further, in the image analysis under the control of the arithmetic control means 19, L1 is corrected to the actual size based on the image scale value, and the lateral shaking width of the passenger can be obtained as the actual size.

  Further, the CPU 19 compares the calculated lateral swing width of the passenger with the normal walking determination value (15 cm) stored in the ROM 16, and if the lateral swing width is equal to or larger than the normal walking determination value, the passenger walking It is determined that the state is abnormal, and data on the slow operation speed is output to the escalator control panel 14. Further, at the same time when the data of the slow operation speed is sent to the escalator control panel 14, a timer built in the CPU 19 starts counting. And the operation state of the escalator apparatus 2 is maintained until the count by a timer passes passing time.

At the same time as the passing time elapses, the CPU 19 sends data on the normal operation speed to the escalator control panel 14.
In addition, when the roll width is equal to or less than the normal walking determination value, the CPU 19 determines that the walking state of the passenger is not abnormal, and the operation state of the escalator device 2 in which the tread plate 7 travels at the moving speed at the normal driving speed is determined. To be maintained.

  If the CPU 19 determines that the walking state of the passenger trying to get into the escalator device 2 is abnormal while the timer counter is operating, the timer counter is reset and then started again. The operation state of the escalator device 2 is maintained until the count of the time passes.

  Next, the operation of the escalator control panel 14 will be described. When the escalator control panel 14 receives the data of the slow operation speed from the analysis control unit 4 while the movement speed of the tread 7 is controlled at the normal operation speed, the movement speed of the tread 7 is moderately lower than the normal operation speed. Control to switch to the slow driving speed. If there is a passenger who is already on the tread board 7 of the escalator device 2, since the moving speed of the tread board 7 is gently switched, acceleration due to sudden speed switching is not applied to the passenger. The escalator device 2 can be smoothly operated without impairing the comfort.

  Furthermore, the escalator control panel 14 receives normal operation speed data from the analysis control unit 4 when the count of the timer of the CPU 19 continues for a given time or more, and accelerates the moving speed of the tread 7 until the normal operation speed is reached. Thus, the escalator device 2 is controlled. Thereby, when the passenger judged that the walking state is not abnormal uses the escalator device 2, the moving speed of the tread plate 7 is moved at the normal moving speed, so that the escalator device 2 can be operated efficiently. .

  When the escalator control panel 14 switches from the normal operation speed of the tread plate 7 to the slow operation speed, that is, when the analysis control unit 4 sends the data of the slow operation speed to the escalator control panel 14, the analysis control unit 4 sends “ The moving speed of the tread plate 7 is decelerated. " Thus, since it is possible to notify the passenger in advance that the moving speed of the tread 7 is switched, the passenger can get on the tread 7 without being confused by the speed switching of the tread 7.

  Further, when the escalator control panel 14 switches the moving speed of the tread plate 7 from the slow operating speed to the normal operating speed, the analysis control unit 4 gives an announcement such as “accelerates the moving speed of the tread board 7” to the speaker 20. It is supposed to let you. Since it is possible to notify the passenger in advance that the moving speed of the tread board 7 is switched, even if the passenger remains on the tread board 7, the passenger can get off the tread board 7 without being confused by switching the moving speed of the tread board 7. You can pay attention when you do. In addition, since the passenger judged that the walking state is abnormal gets off from the tread board 7 before the passing time elapses, the passengers left on the tread board 7 here are the passengers judged that the walking state is not abnormal. is there.

Next, the operation flow of the passenger conveyor control device 1 configured and connected as described above will be described based on the flowchart of FIG. In FIG. 5, steps 101 to 111 in the text are referred to as S101 to S111 for convenience.
First, when the passenger conveyor control device 1 is operated, the tread plate 7 of the escalator device 2 travels at a normal operation speed. (Step 101).
The analysis control unit 4 determines whether or not the passenger is displayed on the video imaged by the camera 3 (step 102).

If the CPU 19 determines that no passenger is projected, step 102 is repeated.
If the CPU 19 determines that a passenger has been projected, the process proceeds to step 103.
In step 103, the CPU 19 determines whether or not the walking state of the passenger is abnormal.
If it is determined in step 103 that the walking state of the passenger is not abnormal (normal), the CPU 19 continues the operation of the escalator device 2 that runs the tread 7 at the normal operation speed (step 104). Return.
If it is determined in step 103 that the walking state of the passenger is abnormal, the CPU 19 starts counting a timer built in the CPU 19 (step 105).

Next, the CPU 19 controls the speaker 20 to make an announcement “Decelerate the moving speed of the tread plate 7” to notify the deceleration of the moving speed of the tread plate 7 and at the same time, to the escalator control panel 14 the data of the slow driving speed. The escalator control panel 14 gradually decelerates the moving speed of the tread plate 7 until the slow operating speed is reached. (Step 106).
Next, the CPU 19 determines whether or not a passenger is shown in the video sent from the camera 3 (step 107).
If it is determined in step 107 that no passenger is projected, the process proceeds to step 110.

When it is determined in step 107 that the passenger is projected, the CPU 19 determines whether or not the walking state of the passenger is abnormal (step 108).
When it is determined in step 108 that the walking state of the passenger is abnormal, the CPU 19 resets the timer count, starts the timer count again (step 109), and returns to step 107.
If it is determined in step 108 that the walking state of the passenger is not abnormal, the process proceeds to step 110.

In step 110, the CPU 19 determines whether or not the timer count has exceeded the set transfer time.
If it is determined in step 110 that the timer has not exceeded the set transfer time, the process returns to step 107.
If it is determined in step 110 that the timer has passed the set passing time, the CPU 19 causes the speaker 20 to announce “Accelerate the moving speed of the tread plate 7” and at the same time, data on the normal operating speed. To the escalator control panel 14, and the escalator control panel 14 accelerates the moving speed of the tread plate 7 until it reaches the normal operation speed (step 111).

  According to this Embodiment 1, the passenger who walks toward the footboard 7 on the entrance side of the escalator device 2 is photographed by the camera 3, and the lateral direction relative to the traveling direction of the passenger photographed by the analysis control unit 4 is taken. When the movement is analyzed and it is determined that the walking state of the passenger is abnormal, the slow driving speed data is sent to the escalator control panel 14, and the moving speed of the tread plate 7 of the escalator device 2 passes at the slow driving speed. Since it is driven until it is done, even a person with reduced walking ability, such as a hesitant passenger, can easily get on and off the tread board 7.

Further, when the analysis control unit 4 determines that the passing time has elapsed, normal operation speed data is sent to the escalator control panel 14 and the moving speed of the tread plate 7 is switched to the normal operation speed, so that the escalator device 2 can be efficiently operated. You can drive.
Further, the analysis control unit 4 informs the passenger of the change in the moving speed of the tread board 7 by the speaker 20 and alerts the passenger before switching the moving speed of the tread board 7, so that the tread board 7 of the passenger escalator device 2 is used. You can eliminate the confusion caused by speed switching.

Embodiment 2. FIG.
FIG. 6 is a plan view for explaining an operation in which the arithmetic control means of the passenger conveyor control device according to the second embodiment calculates the walking speed of the passenger, and FIG. 7 is a diagram of the passenger conveyor control device according to the second embodiment. It is a flowchart for demonstrating operation | movement.
In FIG. 7, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The ROM 16 stores a reference walking speed value in advance. The reference walking speed is set to a value such as 1 m / second, which is slightly slower than the normal walking speed of a healthy person. Further, the ROM 16 stores a second image acquisition interval time. Similar to the first image acquisition interval time, the second image acquisition interval time determines the acquisition interval time of still image data of the video imaged by the camera 3. For example, if the second image acquisition interval time is set to 1 second, still images near the entrance every second are stored continuously in the RAM.

  FIG. 6 shows a still image captured by a passenger walking in the direction of the tread board 7 in the video data sent from the camera 3 and a still image acquired after the second image acquisition interval time (after 1 second) has elapsed. The image is a superimposed image superimposed by the control of the CPU 19. The still image is acquired with the same size as the still image, and the image scale value of the still image is the same value as the image scale value of the still image. The distance between the heads in the traveling direction of the passenger is detected as the movement distance L2, and the walking speed of the passenger is determined by dividing the value corrected to the actual movement distance with reference to the image scale value by the second image acquisition interval time. Can be calculated.

  The CPU 19 compares the calculated walking speed of the passenger with the reference walking speed stored in the ROM 16, and if the walking speed of the passenger is equal to or lower than the reference walking speed, the CPU 19 determines that the walking speed of the passenger is abnormal. Speed data is output to the escalator control panel 14. Further, the CPU 19 determines that the walking speed is normal when the walking speed of the passenger is equal to or higher than the reference walking speed, and data on the normal driving speed is output to the escalator control panel 14.

Next, an operation flow of the passenger conveyor control device 1 according to the second embodiment will be described with reference to FIG.
In FIG. 7, Step 201, Step 202, Step 204 to Step 207, and Step 209 to Step 211 are the same as Step 101, Step 102, Step 104 to Step 107, and Step 109 to Step 111 of FIG.

When the CPU 19 determines in step 203 that the walking state of the passenger is abnormal, the process proceeds to step 205. If the CPU 19 determines in step 203 that the walking state of the passenger is not abnormal, the process proceeds to step 212.
If the CPU 19 determines in step 212 that the walking speed of the passenger is not abnormal, the operation of the escalator device 2 is continued at the moving speed of the tread 7 at the normal driving speed (step 204), and the process returns to step 202.

If the CPU 19 determines in step 212 that the walking speed of the passenger is abnormal, the process proceeds to step 205.
If the CPU 19 determines in step 208 that the walking state of the passenger is not abnormal, the process proceeds to step 213. If the CPU 19 determines that the walking state of the passenger is abnormal in step 208, the process proceeds to step 209.
In step 213, when the CPU 19 determines that the walking speed of the passenger is abnormal, the process proceeds to step 209. In step 213, if the CPU 19 determines that the walking speed of the passenger is not abnormal, the process proceeds to step 210.

  According to the second embodiment, the CPU 19 includes a still image in which a passenger walking toward the board 7 on the entrance side is completely reflected, and a still image acquired after the second image acquisition interval has elapsed. By analyzing the superimposed image, detecting the moving distance L2 in the traveling direction of the passenger, and dividing the value corrected to the actual moving distance in consideration of the image scale value by the second image acquisition interval time, The walking speed can be calculated. Then, the CPU 19 determines whether or not the walking speed of the passenger is abnormal by comparing the walking speed of the passenger with the reference walking speed, and for a passenger who is determined to have an abnormal walking speed (person with reduced walking ability). Since the moving speed of the tread 7 of the escalator device 2 is switched to the slow driving speed, even a person with reduced walking ability can easily get on and off the tread 7.

  In the second embodiment, one reference walking speed is stored in the ROM 16, and 1 is determined from two tread board speed setting values according to a determination result obtained by comparing one reference walking speed and a passenger walking speed. However, the ROM 16 has a plurality of reference walking speeds (for example, 4 km / h, 2 km / h to less than 4 km / h, less than 2 km / h) and the ROM 16 is switched to the selected treading speed setting value. , Storing a plurality of tread board speed setting values (for example, high speed driving speed 40m / min, normal driving speed 30m / min, intermediate driving speed 25m / min, slow driving speed 20m / min) The walking speed is compared, and one tread board speed setting value is selected from a plurality of tread board speed setting values according to the result, and the moving speed of the tread board 7 is switched to the selected tread board speed setting value. And it can also be.

In each of the above embodiments, the speaker 20 is used as the notification unit. However, the present invention is not limited to the speaker 20 and is visually notified of the speed change of the tread 7 using a display or the like. Can also be done.
In addition, when a passenger who knows that speed switching may be performed uses the passenger conveyor control device 1 or the like, particularly when there is no need to notify the passenger of a change in the moving speed of the tread plate 7, the speaker 20 There is no need to provide.

  Further, the movement of the step 9 of the escalator device 2 has been described by taking as an example a downward operation from the upper floor side to the lower floor side. However, when the step 9 of the escalator device 2 can be moved and operated in both the upper and lower directions, for example, It can be switched between up and down driving depending on the time of day. When switching to ascending driving, the camera 3 may be disposed on the upper ceiling facing the step board 7 near the lower floor entrance so that the area around the lower floor entrance can be photographed. .

In addition, the escalator device 2 of the passenger conveyor control device 1 has been described as being operated in normal travel as an initial setting when the operation of the passenger conveyor control device 1 is started, but the initial setting is normal travel It is not limited to and can be arbitrarily set.
