Next, following explanation is carried out in the impact that the light of the illumination that arranges in building is caused.
As shown in Figure 2, the light C that enters cylindrical body 9 inside with the angle of incidence α of the angle less than critical angle α 0 is at the internal surface reflection of cylindrical body 9 and move on, thereby produces the phenomenon that light enters the visual field of pick up camera, namely produces and is shining into (Xie り Write む).As the counte-rplan that are shining into of this light, need light at least externally to arrive reflection on the inside face that is suppressed at cylindrical body 9 before the camera field of view.
Next, if the antireflection object 15 of the sealing band (seal) of stickup or coating etc. is set at the half cycle with pick up camera is taken an opposite side of direction of cylindrical body 9, then can not produce being shining into of light, the scope that arranges of such antireflection object 15 is described.
At first, the light C of angle of incidence α advances at the internal surface reflection of the cylindrical body 9 of inside diameter D i and in the vertical surface of the center shaft by cylindrical body 9, arrive at light in the situation of camera field of view lower extreme point A, the distance L 2 between the subpoint B of the lower extreme point A of camera field of view and the reflection of two vicinities can be tried to achieve by L2=2 * Di * tan α.As described above, by taking at pick up camera on the opposing face of direction, on above-below direction from camera field of view lower extreme point A to subpoint B, the antireflection object 15 of having pasted sealing band (seal) or having applied coating etc. is set to the scope of the position at the left and right fields of vision angle of pick up camera on left and right directions, can suppresses extraneous light being shining into to camera field of view.
In addition, spend near 90 from critical angle α 0 along with making angle of incidence, L2 approaches infinitely great, it is desirable to wish that demifacet with the length direction of cylindrical body 9 is all as antireflection object, but consider actual lighting condition, near the situation of angle of incidence α 90 degree is very rare, and the angle of incidence α of the main light that suppresses is α＜α 0, just can access enough effects according to the length that L2=2 * Di * tan α 0 tries to achieve.
The scope that suppresses efficiently to be shining into is to the distance according to L2=2 * Di * L2 that tan α 0 asks from camera field of view lower extreme point A, in the present embodiment, the size of having pasted sealing band or having applied the above-mentioned antireflection object 15 of coating is made as length L d, length L d equals distance L 1 from camera field of view lower extreme point A to the upper end of cylindrical body 9 and adds from camera field of view lower extreme point A according to the L2 that L2=2 * Di * tan α 0 tries to achieve, thereby does not need computation and measurement just can adjust the paste position of antireflection object 15.
In addition, as shown in Figure 4, obtain be positioned at pick up camera 10 about the outer circumference surface of cylindrical body 9 of angle of field θ 2 on subpoint F1, G1 and subpoint F1, G1 from this outer circumference surface extend to subpoint F2, the G2 of inner peripheral surface of the cylindrical body 9 of a side relative with camera field of view along angle of field θ 2, with regard to about angle of field θ 2 in being shining into of light with regard to, in the scope of the circular arc Lb1 of maximum subpoint F1, G1 at outer circumference surface antireflection object 15 is set and gets final product.In addition, minimum antireflection object 15 with being arranged on the formed circular arc Lb2 of each contact at outer circumference surface that the contact F2, the G2 that the make inner peripheral surface center from cylindrical body 9 prolongs, make light by cylindrical body 9 reflection do not enter pick up camera 10 about angle of field θ 2, thereby also can access enough effects.
That is, for the antireflection object 15 of the angle of field θ on left and right directions 2 of pick up camera 10,, to the scope of circular arc Lb1, be arranged on the inner peripheral surface of cylindrical body 9 and get final product at circular arc Lb2, if consider that the outward appearance aspect is then comparatively suitable about the half cycle of cylindrical body 9.
Next, as shown in Figure 5, the opaque film 17 of the integrated of the L font that cover body 16 and antireflection object 15 is overlapped and obtain forms the oblong of the size with length L d and width W d, this length L d is with from the length L a of upper end to the lower end of cover body 16 of cylindrical body 9 and length L c addition and the length that obtains, this width W d is the width about the half cycle of the cylindrical body 9 in the scope from circular arc Lb2 to circular arc Lb1, be provided with a plurality of hole 17a that can insert Screw 14 on top, in order to can carry out the screw thread combination in the angle position consistent with the angle of pick up camera 10, the inside face of pick up camera 10 sides is made the low for example black of brightness reduce the impact that light is shining into, reverse side can be any color, also can draw be used to the statement that arouses attention or pattern, also can put up paster etc.
By making cover body 16 and antireflection object 15 integrated, although when cutting out the opaque film 17 of L font, can produce the N/R part, can easily be installed on the cylindrical body 9 at short notice.
In addition, the material of the opaque film 17 of L font can painted and easy distortion, can be polyester (polyester) resin, resin, paper or the cloth such as vinyl chloride (vinyl chloride) resin, and 0.3mm thickness vinyl chloride is comparatively easy to use.
At this, the material of cover body 16 can be and resin, paper or the cloth such as the opaque film 17 identical alkide resins of L font, Koroseal, aspect outward appearance, be preferably the material identical with the opaque film 17 of L font, and with the top of pick up camera 10 are colors of homology.
Next, the installation steps of pick up camera 10 described.
As shown in Figure 6 and Figure 7, the erection opening 11b that at pick up camera plectane 11A is installed by not shown Screw installs pick up camera 10, hole 11a by means of the specified diameter of the bottom center that is arranged on adjusting device 11, to be connected on the top installation portion 10a of pick up camera 10 by the cable connector 19a of the wiring cable 19 of outer table top 4 wirings from the bottom 6a of escalator 1a, in addition, be fixed on the bottom 6a of escalator 1a by bolt of rear end plate 12a with hanging metal parts 12, utilization is installed near a pair of the hanging that arranges respectively the end of the boatswain chair 11B that erects opposed to each other setting on the plectane 11A at the pick up camera of adjusting device 11 and is used hole 11d, hangs pick up camera 10 and carries out the adjustment of the angle of field of pick up camera 10 in the mode that can swing by suspender 13.
Like this, mounting cylinder shape body 9 just can not implemented the adjustment of pick up camera 10, thereby is convenient to carry out operation.
In addition, as described later, the antireflection object 15 of light of loading and unloading specified length freely has than the large length dimension of scope of angle of field θ 1 up and down, pastes in the mode of the roughly half cycle on the cylindrical body 9 of the relative side at the picture visual angle that covers pick up camera 10.
In addition, by the statement of this antireflection object 15 printings " in pick up camera work " or " please don't lean out health " and so on (also illustration or sign), thereby can doublely do the mischief that prevents the passenger or impel the passenger to note the prompting label of narrow angle section.
In addition, by printing overleaf, the passenger of adjacent escalator also can look and recognize, and at this, by in cylindrical body 9 inboards antireflection object 15 being set, can strengthen to a greater degree the effect of inhibitory reflex.
In addition, antireflection object 15 has from the upper end of cylindrical body 9 at least to the length of the bottom of adjusting device 11, be provided with the banded cover body 16 that is formed by opaque film of the inside face that covers cylindrical body 9, by antireflection object 15 is installed between the inside face of cylindrical body 9 and adjusting device 11 and pick up camera 10, it is in sight that pick up camera 10 and adjusting device 11 are difficult to, thereby hide exist (can hide at least from cylindrical body 9 upper ends to adjusting device 11 bottoms and get final product) of pick up camera 10.
Be arranged on the hole and the excessive swing that is arranged on not shown adjusting device on the outer table top 4 and prevents with line 18 (also can be chain) at the lower quadrate part of cylindrical body 9 cylindrical body 9 of the lower end of cylindrical body 9.
In addition, the view data of pick up camera 10 by wiring cable 19 be recorded in be arranged on the outer table top 4 in be loaded in the not shown video memory of monitoring unit 20, this wiring cable 19 connects up by outer table top 4 from the bottom 6a of escalator 1a.
In addition; the cylindrical body 901～905 of not shown pick up camera in also disposing, the place ahead of the fender guard 701～705 of each narrow angle section shown in Figure 1 is housed; monitoring unit 201 with in the not shown pick up camera that is loaded in the cylindrical body 905 be connected; monitoring unit 202 and cylindrical body 901; 902 two not shown pick up cameras connect, and monitoring unit 203 also is connected respectively with the not shown pick up camera of cylindrical body 903,904 two in addition.
Next, the installation method of the opaque film 17 of the T font that cover body 16 and antireflection object 15 is made of one shape or L font described.
At first, as dead work pick up camera 10 is installed on the adjusting device 11, the forming curves shape is crimp below opaque film, so that the inner peripheral surface butt of opaque film 17 and cylindrical body 9 (the low black-side of brightness is inboard).
The first step is put into the opaque film 17 of doing circlewise to the inboard of cylindrical body 9, and the not shown pair of holes of cylindrical body 9 is overlapped with the hole 17a of opaque film 17.
Second step is installed pick up camera 10 from the top of cylindrical body 9, and is adjusted into the not shown hole that makes cylindrical body 9 and overlaps with the hole 17a of opaque film 17 and the tapped bore 11c of adjusting device 11, thereby cylindrical body 9 and opaque film 17 can be offset.
In the 3rd step, Screw 14 is combined with tapped bore 11c screw thread.At this, as shown in Figure 2, by using the stepwise screw that does not form screw cutting in the given size of nail head below to be used as Screw 14, make Screw 14 when the tapped bore 11c of adjusting device 11 screw thread is combined, if use not the distance piece (distant piece) with the specific thickness of the inwall butt of cylindrical body 9, then can prevent installation portion damaged of cylindrical body 9 or split.
In addition, in the situation of using the general Screw 14 that is formed with screw cutting below the nail head, if between the tapped bore 11c of cylindrical body 9 and adjusting device 11, use not the distance piece with the specific thickness of the inwall butt of cylindrical body 9, then can prevent installation portion damaged of cylindrical body 9 or split.
Like this, opaque film 17 can easily be installed in the inside of cylindrical body 9, thereby can effectively suppress being shining into of light, and the mischief such as can prevent from scrawling.
