The safety device 100 will be described with reference to FIG. FIG. 2 is a drawing showing only the portion related to the safety device 100 in the escalator 10 shown in FIG.

  The safety device 100 includes five first cameras 101 to fifth cameras 105 attached to the ceiling surface of the building 1 and an analysis device 110.

  The first camera 101 is provided on the ceiling surface 4 of the building 1 directly above the lower floor entrance 12a.

  The second camera 102 to the fourth camera 104 are provided on the ceiling surface 4 directly above the intermediate portion 12c provided between the lower floor entrance 12a and the upper floor entrance 12b. Yes, the second camera 102, the third camera 103, and the fourth camera 104 are provided in this order from the lower floor side at a predetermined interval.

  The fifth camera 105 is provided on the ceiling surface 4 of the building 1 just above the entrance / exit 12b on the upper floor side.

  The part where the first camera 101 to the fifth camera 105 capture a moving image is provided directly downward, and as shown in FIGS. 3 (a) and 3 (b), the traveling step 30 and the passenger A riding it are shown. You can shoot from directly above. The first camera 101 to the fifth camera 105 are connected to the analysis device 110.

  The analysis device 110 is connected to a control device 50 provided in the machine room 14. An upper floor speaker 54 and a lower floor speaker 58 are connected to the control device 50. The analysis device 110 determines whether or not the passenger A is looking at the mobile terminal B from the moving images captured by the first camera 101 to the fifth camera 105, and when determining that the passenger A is viewing the control device 50, A notification signal is output.

  When the notification signal is input from the analysis device 110, the control device 50 gives a warning to the passenger A “Please stop using the portable terminal and bring the handrail belt” from the speaker 54 and the speaker 58.

(3) Analysis device 110
A processing method in which the analysis device 110 determines whether or not the passenger A is looking at the mobile terminal B will be described. It is assumed that the escalator 10 is rising, and the passenger A gets in from the lower floor entrance 12a and gets off from the upper floor entrance 12b.

  Each of the first camera 101 to the fifth camera 105 always captures the step 30 directly below with a moving image. The captured moving images of the first camera 101 to the fifth camera 105 are output to the analysis device 110, respectively.

The analysis device 110 stores in advance a first background image captured by the first camera 101 and showing the step 30 and the pair of left and right handrail belts 38 in a state where no passengers are riding. As will be described later, even when comparing with each frame of the moving image, the first camera 101 itself is fixed, so the image seen from above the escalator 10 is the same, so one first Only one background image needs to be stored. In this case, the step 30 and the handrail belt 38 are moving, but when viewed from above, this movement is almost the same in terms of image and does not affect the comparison of the two images. .
Also in the second camera 102 to the fifth camera 105, the analysis device 110 stores the corresponding second background image to fifth background image in advance.

  The analysis device 110 acquires a moving image from the first camera 101 when the escalator 10 starts driving, and an area having a luminance equal to or higher than the reference luminance in the moving image shown in FIG. ”) Is detected, it is determined that the mobile terminal B used in the image exists. Since the image display part of the portable terminal B is brighter than the other areas due to light emission from the backlight or the organic EL, the portable terminal B exists in this high luminance area, and the portable terminal B is used. This is because it can be determined. The analysis device 110 stores a frame of a moving image in which a high luminance area is detected.

  Next, if there is a frame in which a high luminance area is detected in the moving image shown in FIG. 3B taken by the second camera 102, the analysis apparatus 110 also stores the frame.

  Next, the analysis device 110 calculates a difference between the stored frame and the first background image stored in advance, and generates a first difference area in which the step 30 and the handrail belt 38 are removed. The generated first difference area becomes the first passenger area of the passenger A.

  Next, the analysis apparatus 110 similarly generates a second passenger area in the second image.

  Next, the analysis apparatus 110 recognizes and compares the pattern of the first passenger area and the pattern of the second passenger area, and if both patterns are the same, the passenger A remains in the same posture and the mobile terminal B is If it is determined that the two patterns are different, it is determined that the passenger A moves and is not in the same posture. Here, the definition that the posture of the passenger A does not change is that the pattern of the region of the passenger A in the image is exactly the same, and the posture of the passenger A changes even if the position is changed by about 10 to 20 pixels. Judge not to. This is because a state in which the passenger operates the mobile terminal B with his / her finger or shakes his head slightly is included in the same posture. It is important to note that because passenger A is moving on the step 30, even if the first camera 101 and the second camera 102 photograph the passenger A from directly above, they can be photographed in almost the same state. It is possible to make a comparison.

  Even if the high-intensity area is detected in the first image and the second image, the analysis device 110 can detect the passenger A if the posture of the passenger A changes between the first image and the second image. Determines that use of the portable terminal B is stopped.

  Moreover, even if a high-intensity area | region is detected in a 1st image, the analysis apparatus 110 will judge that the passenger A stopped seeing the portable terminal B, when a high-intensity area | region is not detected in a 2nd image.

  In addition, even when the high brightness area is not detected in the first image and the second image, the analysis device 110 detects the high brightness area in the third image and detects the high brightness area in the fourth image, It is determined that the passenger A starts using the mobile terminal B from the middle of the escalator 10.

(4) Processing Method of Safety Device 100 Next, a processing method of the safety device 100 will be described with reference to the flowchart of FIG.

  In step S1, as an initial setting, the analysis apparatus 110 acquires and stores the first background image to the fifth background image of the first camera 101 to the fifth camera 105, and proceeds to step S2.

  In Step S2, control device 50 starts operation of escalator 10, and proceeds to Step S3.

  In step S3, the analysis apparatus 110 sets camera number k = 1, and proceeds to step S4.

  In step S4, the analysis apparatus 110 acquires the first image of the first camera 101 (k-th image of the k-th camera), and proceeds to step S5.

  In step S5, if the analysis apparatus 110 detects a high brightness area in the first image, the process proceeds to step S8 (in the case of Y), and if not detected, the process proceeds to step S6 (in the case of N).

  In step S6, the analysis apparatus 110 ends if the camera number k is 5 = k (in the case of Y), and proceeds to step S7 in the case of 5 <k (in the case of N).

  In step S7, the analysis device 110 sets camera number k = k + 1 and returns to step S4.

  In step S8, the analysis apparatus 110 acquires the second image of the second camera 102 ((k + 1) th image of the (k + 1) th camera), and proceeds to step S9.

  In step S9, if the analysis apparatus 110 detects a high brightness area in the second image, the process proceeds to step S10 (in the case of Y), and if not detected, the process proceeds to step S14 (in the case of N).

  In step S10, the analysis device 110 compares the first image with the second image, analyzes whether there is a change in the posture of the passenger A, and proceeds to step S11.

  In step S11, if there is a change in the posture of passenger A, it is determined that there is a possibility that the use of mobile terminal B has been stopped, and the process proceeds to step S14 (in the case of Y). The process proceeds to step S12 (in the case of N).

  In step S12, it is notified by voice that the passenger A is using the portable terminal B, and the process proceeds to step S13.

  In step S13, the analysis apparatus 110 ends if the camera number k is 5 = k + 1 (if Y), and proceeds to step S14 if 5 <k + 1 (if N).

  In step S14, the analysis apparatus 110 sets camera number k = k + 2 and returns to step S4.

(5) Effect According to the present embodiment, if the posture of the passenger A does not change, it is assumed that the passenger A is looking at the mobile terminal B, a warning is given, and the posture of the passenger A is detected even if a high-luminance region is detected. Is changed, passenger A is not watching mobile terminal B and no warning is given. Therefore, it is possible to ensure the safety of passengers.

However, the present invention is not limited to this, and the high-luminance region is detected in the image captured by one of the first camera 101 to the fifth camera 105 without detecting the posture. In such a case, it may be determined that the passenger A is looking at the mobile terminal B and may give a warning.

(2) Modification example 2
In the above-described embodiment, five cameras 101 to 105 are used. For example, only one camera is provided on the ceiling surface of the entrance and exit, and whether or not the mobile terminal B is used by shooting a moving image with the camera. It can also be judged.

  In this case, when the first frame and the last frame of the moving image captured by the camera are compared, a high brightness area is detected, and the posture of the passenger A has not changed between frames. A warning is given that the mobile terminal B is being used.

(3) Modification 3
In the above embodiment, the background image is stored in advance in order to detect the area of the passenger A. However, the area of the passenger A may be detected by other methods.

(4) Modification 4
Although the escalator 10 has been described as a passenger conveyor in the above embodiment, it may be applied to a moving sidewalk instead.
