It is a block diagram which shows the system configuration | structure of a form.

  In FIG. 1 to FIG. 9, an escalator 1 constituting an escalator arrangement structure is installed across an upper floor and a lower floor, and a handrail 2 that holds a passenger and a balustrade that supports the mobile handrail 2. 3, an outer deck 4 that holds the balustrade 3 from the outside, and a control device 5 for the escalator 1, and 6 is a bottom portion of the escalator 1.

  The escalator arrangement structure targeted by the present embodiment includes escalators 1a, 1b, and 1c similar to the escalator 1, and has a total of four escalators. Here, the escalator 1 performs the ascending operation from the first floor to the second floor, the escalator 1a performs the descending operation from the second floor to the first floor, the escalator 1b performs the ascending operation from the second floor to the third floor, and the escalator 1c. Is a descent operation from the third floor to the second floor.

  In addition, this escalator arrangement structure is in the escalators 1, 1 a, 1 b, 1 c that are provided side by side with each other, and a narrow-angle portion formed between the moving handrail 2 of the escalator 1 and the bottom portion 6 a of the escalator 1 a, A swingable protection to make the passenger aware of the danger when the passenger touches it in order to prevent the passenger from being caught between the moving handrail 2 of the escalator 1 and the narrow angle portion formed between the bottom portion 6b of the escalator 1b. A device 7 is arranged, and a protective device 8 that is firmly fixed to the bottom of the escalator 1 is arranged.

  The cylindrical body 9 is disposed in front of the protective device 7 and the material thereof is made of the same transparent acrylic material as the cylindrical body attached to the protective device 7 and is suspended so as to be swingable. When the passenger collides, the passenger is not injured. The length of the cylindrical body 9 may be such that the lower end is 200 mm or more lower than the upper end of the moving handrail 2 by hanging.

  A camera 10 that monitors the passenger of the escalator 1, that is, a camera 10 to which a dome 10 </ b> A that captures how to ride the passenger on the escalator 1 is mounted is disposed at the inner upper end of the cylindrical body 9.

  The camera 10 is fixed to a mounting jig 11 bent in a U-shape with a fastening bolt 10a through a mounting hole 11A provided in the U-shaped bottom surface, and the hanging metal fitting 12 is fixed to the bottom 6a of the escalator 1a with a fixing bolt 12a. The camera 10 is suspended by a lifting tool 13 so that the camera 10 can swing in a pair of suspension holes 11a provided in the vicinity of the ends of the U-shaped single-sided surfaces 11B of the mounting jig 11. .

  The mounting jig 11 is provided with a pair of screw holes 11b below the suspension holes 11a, and screws 14 are screwed into a pair of holes (not shown) provided in the diameter direction of the cylindrical body 9, respectively. 11 is fixed to the cylindrical body 9.

  Next, a procedure for mounting the camera 10 will be described.

  After the camera 10 is screwed into the mounting hole 11A of the mounting jig 11 with the fastening bolt 10a, the hanging tool 13 is attached to the hanging hole 11a and suspended from the hanging metal fitting 12, and the viewing angle of the camera 10 is adjusted. I do.

  As described above, since the camera 10 can be adjusted without attaching the cylindrical body 9, the operation can be easily performed.

  Moreover, each suspension hole 11a extension line is made the same as the inclination angle of the bottom part 6 of the escalator 1 with respect to the bottom surface where the attachment hole 11A of the attachment jig 11 is provided, so that the suspension 13 has the same shape. Since the bottom surface on which the mounting hole 11A is provided is horizontal, the viewing angle of the camera 10 can be easily adjusted.

  The camera 10 housed inside the cylindrical body 9 has an upper and lower viewing angle θ1 and a left and right viewing angle θ2 which will be described later, and is a sticker 15 that is an antireflection body for a predetermined length of light that can be pasted. As will be described later, this has a length dimension larger than the range of the vertical viewing angle θ1, and is attached so as to cover a substantially half circumference of the cylindrical body 9 on the side opposite to the angle of view of the camera 10. In addition, this sticker 15 can also be printed as a warning label to prevent passengers from mischief and alerting to a narrow-angle area by printing the words “Camera is in operation” and “Care to get on”. ing. Moreover, it can also visually recognize from the passenger of an adjacent escalator by printing on both back surfaces. Here, the seal 15 is attached to the outside of the cylindrical body 9, but if it is attached to the inside, the effect of preventing reflection is increased.

  Between the inner surface of the cylindrical body 9 and the mounting jig 11 and the camera 10, a belt-like cover body 16 formed of an opaque film having a length from the upper end of the cylindrical body 9 to the vicinity of the center of the camera 10 is provided. The camera 10 and the mounting jig 11 are made difficult to see, and the presence of the camera 10 is concealed (at least it should be possible to hide from the upper end of the cylindrical body 9 to the lower end of the mounting jig 11). Here, the detailed description of the structure of the anti-reflective body and cover body 16 demonstrated as the seal | sticker 15 mentioned above and the attachment method to the cylindrical body 9 is mentioned later.

  The lower part of the cylindrical body 9 stores a notification body 17 that rings for a predetermined time by detecting a predetermined vibration and a predetermined inclination, and performs a warning ring for passengers who collide with the cylindrical body 9 and passengers around it. Excessive vibration of the cylindrical body 9 is prevented by a hole 18 provided at the lower end of the cylindrical body 9 and a mounting jig (not shown) provided on the outer deck 4 by a wire 18 (or a chain).

  The video data of the camera 10 is stored in an image memory 102 (described later) built in the monitoring unit 20 installed on the outer deck 4 via a wiring cable 19 wired from the bottom 6a of the escalator 1a through the outer deck 4. Is to be recorded.

  In addition, cylindrical bodies 901 to 905 each having a camera (not shown) built therein are also arranged in front of the protective devices 701 to 705 at each narrow angle portion shown in FIG. 1, and the monitoring unit 201 is built in the cylindrical body 905. To the monitoring unit 202, two cylindrical cameras 901 and 902 (not shown) are connected, and the monitoring unit 203 also has two cylindrical bodies 903 and 904 (not shown). Each camera is connected.

  Next, the influence on the light of the illumination provided in a building is demonstrated.

  In FIG. 4, light C <b> 1 that enters the acrylic part 9 </ b> A forming the cylindrical body 9 with an incident angle α of 0 to 90 degrees reflects light when it hits the acrylic part 9 </ b> A on the inner surface that is the inner wall of the cylindrical body 9. There are three types: C2, light C3 that enters the acrylic part 9A and travels inside the acrylic part 9A, and light C4 that passes through the inner surface of the acrylic part 9A and exits from the outer surface. Here, the critical angle α0 for total reflection is obtained by α0 = arcsin (ηa / ηb) when the refractive index of air ηa and the refractive index of acrylic ηb, and when the incident angle of light is larger than the critical angle α0. When the light is reflected by the acrylic part 9A like the light C2 and the incident angle of light is smaller than the critical angle α0, the light passes through the acrylic part 9A and goes out of the cylindrical body 9 like the light C4.

  On the other hand, as shown in FIG. 5, the light C entering the cylindrical body 9 at an incident angle α which is smaller than the critical angle α0 travels while reflecting the inner surface of the cylindrical body 9 and enters the field of view of the camera. A phenomenon, so-called reflection occurs. As a countermeasure against this reflection of light, it is necessary to suppress reflection on the inner surface of the cylindrical body 9 at least before outside light reaches the camera field of view.

  Next, if an antireflection body such as sticking of a seal 15 or application of paint is provided on the half circumference opposite to the camera imaging direction of the cylindrical body 9, no reflection will occur, but the range in which such an antireflection body is provided. Will be explained.

  First, when the light C of the incident angle α reflects the inner surface of the cylindrical body 9 having the inner diameter Di, proceeds in the vertical plane passing through the central axis of the cylindrical body 9, and reaches the lower end point A of the camera field, The distance L2 from the projection point B that is reflected two points before the lower end point A is obtained by L2 = 2 × Di × tanα, and as described above, on the opposite side of the camera imaging direction, the lower end of the camera field in the vertical direction By providing an anti-reflective body such as applying a seal 15 or applying paint on the left and right viewing angles of the camera from the point A to the projection point B, it is possible to suppress the reflection of external light in the camera field of view. it can.

  Further, since L2 approaches infinity as the incident angle approaches 90 degrees from the critical angle α0, ideally, it is desirable that all the half surfaces in the length direction of the cylindrical body 9 be antireflection bodies. Considering the illumination conditions, it is rare that the incident angle α is in the vicinity of 90 degrees, and the length obtained by L2 = 2 × Di × tan α0 is assumed to be mainly suppressed when the incident angle α of light is α <α0. A sufficient effect can be obtained.

  The range in which the reflection is efficiently suppressed is the distance L2 obtained by L2 = 2 × Di × tanα0 from the lower end point A of the camera field of view, and in this embodiment, the above-described antireflection such as sticking of the seal 15 or coating of the paint is performed. The body dimension is set to a length La obtained by adding a distance L1 from the lower end point A of the camera field of view to the upper end of the hood of the camera and L2 obtained from the lower end point A of the camera field of view by L2 = 2 × Di × tanα0. The position can be adjusted without measuring.

  Further, as shown in FIG. 6, the projection points F1 and G1 on the outer peripheral surface of the cylindrical body 9 at the left and right viewing angles θ2 of the camera 10 and the anti-camera at the viewing angle θ2 from the projection points F1 and G1 on the outer peripheral surfaces. The projection points F2 and G2 on the inner peripheral surface of the cylindrical body 9 extended to the visual field side are obtained, and the maximum reflection of light at the left and right viewing angles θ2 is within the range of the arc Lb1 of the projection points F1 and G1 on the outer peripheral surface. The antireflection body provided on the arc Lb2 formed by the respective contacts on the outer peripheral surface obtained by extending the contacts F2 and G2 on the inner peripheral surface from the center of the cylindrical body 9 may be provided. However, since the light reflected by the cylindrical body 9 does not enter the left and right viewing angles θ2 of the camera 10, a sufficient effect can be obtained.

  That is, the antireflection body for the left and right viewing angles θ2 of the camera 10 may be provided on the inner peripheral surface of the cylindrical body 9 in the range from the arc Lb2 to the arc Lb1, and the design surface of the cylindrical body 9 is considered in consideration of the design surface. Near half circumference is suitable.

  Next, as shown in FIG. 7, the antireflection body 25 has a length Ld obtained by adding the length Lc and the length La of the upper end of the camera hood 10A from the upper end of the cylindrical body 9, and the arc Lb2 to the arc Lb1. A strip shape having a width Wd in the vicinity of a half circumference of the cylindrical body 9 is formed in a range, and a plurality of holes 25a into which screws 14 can be inserted are provided in the upper portion, and the surface on the camera 10 side is projected as low brightness, for example, black. However, it may be of any color, may be drawn with words and patterns for caution ventilation, or a sticker 15 may be affixed.

  The material of the antireflective body 25 can be colored and easily deformed, and can be a resin such as polyester or vinyl chloride, paper, or cloth as long as the seal 15 can be applied or peeled off. Vinyl is easy to handle.

  The cover body 16 has a substantially belt-like shape. In the vicinity of the upper side of the cover body 16, the upper end portion of the cylindrical body 9 and the dimension of a pair of holes (not shown) and the dimension between the pair of holes (cylindrical shape) Two holes 16a are provided from the upper side of the cover body 16 with the same dimension as the half circumference dimension of the inner surface of the body 9, and a notch 16c of a predetermined length and a left side of the cover body 16 are provided in the vicinity of the right side edge of the cover body 16. Has an insertion portion 16b that can be inserted into the notch 16c. When the insertion portion 16b is inserted into the notch 16c, the cover body 16 becomes an annular body having the same dimensions as the inner periphery of the cylindrical body 9, and the upper side of the cover body 16 Is aligned with the upper end of the cylindrical body 9, the two holes 16 a match a pair of holes (not shown) of the cylindrical body 9. Here, the material of the cover body 16 may be the same resin, paper, or cloth such as polyester and vinyl chloride as the antireflection body 25. The same material as the antireflection body 25 is desirable in design, and the thickness is the antireflection body 25. The thinner one is easier to handle.

  Next, a method for attaching the cover body 16 and the antireflection body 25 will be described.

  First, as a preparatory work, the camera 10 is attached to the attachment jig 11, the insertion portion 16 b is inserted into the notch 16 c of the cover body 16 to make the cover body 16 annular, and the antireflection body 25 is the inner peripheral surface of the cylindrical body 9. A curved wrinkle is attached below the antireflective body 25 so as to come into contact with (a black side with low lightness is on the inside).

  First, an annular cover body 16 is inserted into the upper part of the cylindrical body 9, and a pair of holes (not shown) of the cylindrical body 9 and the holes 16a of the cover body 16 are aligned.

  Second, the hole 25 a of the antireflection body 25 is overlapped with the hole 16 a of the cover body 16.

  Third, the cylindrical body 9, the cover body 16, and the antireflection body 25 are not displaced, and the camera 10 is mounted from above the cylindrical body 9. The hole 25a is adjusted so that the hole 16a of the cover body 16 and the screw hole 11b of the mounting jig 11 are matched.

  Fourth, the screw 14 is screwed into the screw hole 11b.

  Since it did in this way, the antireflection body 25 can be easily attached to the inside of the cylindrical body 9, and reflection by light can be effectively suppressed and mischief such as graffiti can be prevented.

  In addition, by sticking the seal 15 on the outside of the antireflection body 25, the same effect as when the seal 15 is stuck on the cylindrical body 9 can be obtained. Here, if there is a deviation between the shooting direction of the camera 10 and the traveling direction of the escalator, the characters described on the seal 15 become difficult to see. Therefore, by changing the plurality of holes 25a provided in the upper part of the antireflection body 25, the escalator is changed. The traveling direction of the seal 15 and the seal 15 are in the same direction, and the characters on the seal 15 are easy to read from the passenger of the escalator.

  Further, as shown in FIG. 8, a T-shaped antireflection body 26 including the cover body 16 and the antireflection body 25 includes an attachment hole 26a, a cut 26c, and an insertion portion that can be inserted into the cut 26c. 26b, and has the same length Ld as the antireflection body 25.

  Although the mounting method of the T-shaped antireflection body 26 shown in FIG. 8 is omitted, a portion that is wasted when the T-shaped antireflection body 26 is cut out by integrating the cover body 16 and the antireflection body 25. However, attachment to the cylindrical body 9 becomes easy and can be performed in a short time.

  Next, recording of image data taken by the camera 10 will be described.

  In FIG. 9, photographing data photographed by the camera 10 housed in a cylindrical body 9 hanging forward of the protection device 7 of the escalator 1 is sent to a monitoring unit 20, and an input unit 101 of the monitoring unit 20 is A signal from the camera 10 is received, converted into digital data, and transmitted to the image memory 102. The image memory 102 captures and stores the transmitted digital image data at a cycle of, for example, every second.

  Next, the image processing unit 103 performs image processing on the image data stored in the image memory 102 to create current image data for image recognition determination processing, and the image recognition unit 104 is sent from the image processing unit 103. The current image data is compared with the basic image previously captured by the camera 10, and if the difference value of the image exceeds a predetermined value, a notification signal is output to the guide unit 105.

  In accordance with the determination result of the image recognition unit 104, the guide unit 105 announces a pre-recorded caution broadcast or issues a warning. The output unit 106 transmits a signal from the guide unit 105 to the control unit 5 of the escalator 1. Here, the controller 5 can decelerate or stop the escalator 1 by the transmitted signal.

  According to the first embodiment configured as described above, the cylindrical body 9 that hangs down in front of the protective device 7 disposed at the narrow angle portion, and the monitoring camera 10 on the inner side of the cylindrical body 9. Because it is housed, the camera for monitoring can be installed in a good position where it is possible to monitor the rising and falling of passengers without being affected by the ceiling and wall structure of the building around the escalator. The installation restriction of the received camera can be eliminated, and the installation cost of the escalator monitoring device can be reduced. The same applies to the other cylindrical bodies 901-905.

  Moreover, according to 1st Embodiment, since the camera 10 is accommodated in the inside of the cylindrical shape body 9 without exposing, while being able to ensure the outstanding design property, the mischief with respect to the camera 10 of a passenger can be prevented. Further, since the shape of the mounting jig 11 of the camera 10 is a U-shape, the member of the mounting jig 11 and the hanging tool 13 do not come out of the outer periphery of the cylindrical body 9. Injury can be suppressed even if the upper end of the cylindrical body 9 is touched by mistake during traveling.

  In addition, the camera provided in the cylindrical body 901 can monitor not only passengers rising on the escalator 1, but also passengers crossing and descending on the adjacent escalator 1a. Monitoring is possible.

  In addition, since the seal 15 covers about half of the counter-angle of view of the camera 10, it prevents outside light such as illumination reflected through the cylindrical body 9 from entering the viewing angle of the camera. Therefore, it is possible to obtain an excellent image that is less affected by the lighting of the building and external light.

  In addition, since the cover body 16 is provided on the upper inner peripheral surface of the cylindrical body 9, the mounting jig 11, the camera fixing bolt 10a, the cable connector 19a, etc. are not noticed by the passenger, so that the design is excellent.
