The following describes being arranged on the influence of the illumination light on the building.
Among Fig. 4, spend to the angle of incidence α of 90 degree with 0 and to incide the light C1 of the 9A of propylene portion that forms cylindrical body 9, touch the 9A of propylene portion as the inside of cylindrical body 9 inwalls after, be divided into following 3 kinds: the light C2 of reflection; The light C3 that enter propylene portion 9A inside, advances in propylene portion 9A inside; The light C4 that see through the 9A of propylene portion inner face, penetrates from the outside to the outside.Here, the critical angle α 0 of total internal reflection is η a at air refraction, when the propylene ratio of refraction is η b, obtain by α 0=arcsin (η a/ η b), when the angle of incidence of light is bigger than critical angle α 0, as light C2, on the 9A of propylene portion, reflect, angle of light sees through the 9A of propylene portion and injects to cylindrical body 9 outsides than critical angle α 0 hour as light C4.
In addition, as shown in Figure 5, in cylindrical body 9 inside, the phenomenon of advancing, entering camera coverage with the light C of the angle angle of incidence α incident littler than critical angle α 0 in the reflection of cylindrical body 9 inner faces takes place, and is just so-called reflective.As reflective countermeasure, needing at least outside, light arrives the reflection that camera coverage suppresses cylindrical body 9 inner faces before.
The pick up camera of cylindrical body 9 is taken on the opposition side half cycle of direction, waits reflection to prevent body if be provided with the stickup and the smearing of coating of strip of paper used for sealing 15, and is reflective with regard to not taking place, and the following describes the scope that above-mentioned reflection prevents body that is provided with.
At first, the light C of angle of incidence α is in the cylindrical body 9 inner faces reflection of inside diameter D i, in vertical surface, advance by cylindrical body 9 center shafts, when arriving camera coverage lower extreme point A, the distance L 2 of subpoint B before camera coverage lower extreme point A and 2 secondary reflections is obtained by L2=2 * Di * tan α, as above-mentioned, prevent body by on the opposite face of taking direction at pick up camera reflection being set, it is to subpoint B from camera coverage lower extreme point A for above-below direction, left and right directions is from the stickup of strip of paper used for sealing 15 at pick up camera left and right fields of vision angle or smearing of coating, and it is reflective in camera coverage to suppress outer light thus.
And, angle of incidence is from critical angle α 0, more near 90 degree, the approaching more infinity of L2, so it is desirable to the demifacet of cylindrical body 9 length directions is all prevented body as reflection, but consider actual lighting condition, angle of incidence α is seldom near 90 degree, the angle of incidence α major control of light also can have enough effects by the length that L2=2 * Di * tan α 0 obtains when α＜α 0.
Effectively suppress reflective scope and be from camera coverage lower extreme point A, by the distance of L2=2 * Di * L2 that tan α 0 obtains, in the present embodiment, the above-mentioned reflection such as smear of the stickup of strip of paper used for sealing 15 or coating prevents that body is of a size of: the distance L 1 from camera coverage lower extreme point A to shooting hood upper end adds does not measure the paste position that just can adjust strip of paper used for sealing 15 from camera coverage lower extreme point A, by the length L a of L2=2 * Di * L2 that tan α 0 obtains.
As shown in Figure 6, obtain the subpoint F1 of cylindrical body 9 outer peripheral faces among the pick up camera 10 left and right view field angle θ 2, G1, among the angle of visibility θ 2 from this outer peripheral face subpoint F1, G1 is to the subpoint F2 of cylindrical body 9 inner peripheral surfaces of anti-camera coverage side prolongation, G2, reflective among the left and right view field angle θ 2, maximum can be at the subpoint F1 of outer peripheral face, reflection is set in the circular arc Lb1 scope of G1 prevents body, the minimum contact F2 that can prolong inner peripheral surface from the center of cylindrical body 9, G2, with reflection be set on the formed circular arc Lb2 of each contact of outer peripheral face prevent body, like this, light by cylindrical body 9 reflections can not enter pick up camera 10 left and right view field angle θ 2, so can access enough effects.
That is, relatively the reflection of pick up camera 10 left and right view field angle θ 2 prevents body, as long as in scope from circular arc Lb2 to circular arc Lb1, be arranged on cylindrical body 9 inner peripheral surfaces just passable, if consider design aspect, better near cylindrical body 9 half cycles.
Then, as shown in Figure 7, reflection prevents that body 25 from forming oblong, it is of a size of: length L d is for adding length L a from cylindrical body 9 upper ends to the length L c of shooting hood 10A upper end, wide Wd is in the scope from circular arc Lb2 to circular arc Lb1, near cylindrical body 9 half cycles, top is provided with a plurality of hole 25a that can insert screw 14, the face of pick up camera 10 sides be lightness lower as black, can reduce reflective influence, reverse side is that any color can, can indicate that also the literal and the figure that point out release, paste strip of paper used for sealing 15 and also can.
And reflection prevents that the material of body 25 from being pigmentable and easy deformation, if can paste, peel off strip of paper used for sealing 15, resins such as polyester, vinyl chloride, paper, cloth also can, the vinyl chloride of 0.3mm thickness uses more convenient.
The following describes the installation method that lid 16 and reflection prevent body 25.
At first, as beamhouse operation, pick up camera 10 is installed on the mounting tools 11, make lid 16 be ring-type behind the otch 16c with insertion section 16b insertion lid 16, below reflection prevents body 25, make curve-like and crease, make reflection prevent that body 25 from contacting (making the lower black-side of lightness for inboard) with cylindrical body 9 inner peripheral surfaces.
The 1st step, the lid 16 of ring-type is put into cylindrical body 9 tops, pair of holes not shown in the cylindrical body 9 is alignd with the hole 16a of lid 16.
In the 2nd step, make reflection prevent to overlap after the hole 25a of body 25 from aliging with the hole 16a of lid 16.
The 3rd step, make cylindrical body 9, lid 16 and reflection prevent that body 25 from not staggering, from cylindrical body 9 tops pick up camera 10 is installed, is adjusted, make hole not shown in the cylindrical body 9 prevent that with reflection the hole 25a of body 25 and the hole 16a of lid 16 and the tapped bore 11b of mounting tools 11 from aliging.
In the 4th step, screw 14 is screwed on the tapped bore 11b.
Like this, reflection prevents that body 25 just can be easily mounted on cylindrical body 9 inside, can effectively suppress reflective, and the while such as can prevent to scratch at mischief.
And reflection prevents that body 25 outsides are pasted with strip of paper used for sealing 15, can access with cylindrical body 9 on paste the identical effect of strip of paper used for sealing 15.Here, if the shooting direction of pick up camera 10 and escalator operation direction stagger, can be difficult to see the literal of being put down in writing on the strip of paper used for sealing 15, prevent a plurality of hole 25a on body 25 tops so be arranged on reflection by change, can make strip of paper used for sealing 15 directions identical with the escalator operation direction, the literal that makes strip of paper used for sealing 15 is on the position that the escalator passenger sees easily.
As shown in Figure 8, lid 16 and reflection prevent that the T font reflection that body 25 is combined into from preventing that the top of body 26 has: mounting hole 26a; Otch 26c; Can insert the insertion section 26b of this otch 26c, length L d prevents that with reflection body 25 is identical.
Omit the installation method that T font shown in Figure 8 reflection prevents body 26, by lid 16 and reflection are prevented that body 25 is integrated, can produce the part of waste when the reflection of T font prevents body 26 cutting, but be installed to easily on the cylindrical body 9, and can carry out at short notice.
Then explanation is by the record of pick up camera 10 shot image data.
Among Fig. 9; the camera data that the pick up camera that held by cylindrical body 9 inside of hanging down in fender guard 7 the place aheads of escalator 1 10 is captured; send to monitoring unit 20; the signal that the input part 101 of this monitoring unit 20 receives from pick up camera 10; send on the shadow memory 102 after being converted to digital data, this shadow memory 102 for example reads and stores the digital image data that sends with the cycle of per second.
Then, the image data of storage carries out image processing in 103 pairs of shadow memories 102 of image processing portion, make the existing image data that the judgment processing that is used for image identification is used, image processing portion 103 existing image data that sends and the basic image of being taken by pick up camera 10 are in advance made comparisons in image identification part 104, after the image difference value surpasses specified value, to guide portion 105 output alarm signals.
The 1st embodiment according to said structure; be arranged on the cylindrical body 9 that hangs down in fender guard 7 the place aheads in the narrow angle portion; and these cylindrical body 9 private sides accommodate camera for monitoring 10; thus; not influenced by the top ceiling of escalator surrounding buildings and wall construction; can on the good locations of monitored passenger jacking condition camera for monitoring be installed, the above-mentioned pick up camera that can eliminate building is provided with regulation, can reduce the establishment charges of this escalator monitor unit simultaneously.Other cylindrical body 901-905 also is the same.
