In addition, car control part the 10, the 1st object detection control part the 11, the 2nd object detection control part 12 and open and close controlling portion 14 all have microcomputer, can carry out separately function according to the program in the microcomputer of being stored in.
Fig. 3 is the block diagram of expression the 2nd framework 5 shown in Figure 1.The 2nd framework 5 has the framework main body (tectosome) 21 of front surface opening and is located at the separator of battery plates 22 of the Width pars intermedia in the framework main body 21.And, be provided with upper cap 23 in the upper end of framework main body 21, be provided with lower cover 24 in the bottom of framework main body 21.
Two spaces, i.e. illuminator chamber 21a and image unit chamber 21b about spaces in the framework main body 21 are separated plate 22 and are divided into.The 2nd illuminator 8 is configured among the 21a of illuminator chamber.The 2nd pick up camera 9 is configured in the bottom of image unit chamber 21b.Separator of battery plates 22 is to be used for light transmissive parts that the 2nd illuminator 8 is sent, so that light can not leak between illuminator chamber 21a and image unit chamber 21b.
Front surface at illuminator chamber 21a is provided with the transmission diffusing panel 25 that makes transmittance/diffusion.The front surface opening of illuminator chamber 21a is blocked by transmission diffusing panel 25.Transmission diffusing panel 25 can use for example milky resin board of semi-translucent or surperficial transparent resin plate or the glass board that is implemented DIFFUSION TREATMENT.And the 2nd emitting surface 8a utilizes transmission diffusing panel 25 to form.
Front surface at image unit chamber 21b is provided with shade 26.Shade 26 makes from the i.e. transmittance of the 1st illuminator 6 of the illuminator relative with it, and at least a portion of blocking the light of the wavelength except that this light wavelength.That is, shade 26 blocks the light of object detection institute N/R wavelength as optical filter, optionally makes the transmittance from the 1st illuminator 6.And shade 26 can use for example resin board or glass board.
Fig. 4 is the longitudinal diagram of the illuminator chamber 21a of the 2nd framework 5 shown in Figure 3, Fig. 5 is the longitudinal diagram of the image unit chamber 21b of the 2nd framework 5 shown in Figure 3, Fig. 6 is the section-drawing along the VI-VI line of the 2nd framework 5 shown in Figure 5, and Fig. 7 is the section-drawing along the VII-VII line of the 2nd framework 5 shown in Figure 5.
The 2nd illuminator 8 has: substrate 27, and it is located in the 21a of illuminator chamber, and relative with transmission diffusing panel 25; A plurality of light sources (point source of light) 28, it is installed on the substrate 27 in the compartment of terrain that separates each other on the above-below direction; And transmission diffusing panel 25.All light sources 28 and transmission diffusing panel 25 are relative and separate predetermined interval with transmission diffusing panel 25.
The 2nd pick up camera 9 is configured in the bottom of image unit chamber 21b, and tilts towards oblique upper.The 2nd object detection control part 12 is housed in the top of the 2nd pick up camera 9 in the 21b of image unit chamber, and near the 2nd pick up camera 9.
The structure of the 1st framework 4 is identical with the 2nd framework 5.In the 1st framework 4, shade 26 makes from the i.e. transmittance of the 2nd illuminator 8 of the illuminator relative with it, and at least a portion of blocking the light of the wavelength except that this light wavelength.The 1st illuminator 6 and the 2nd illuminator 8 are configured in the 21a of illuminator chamber in the same manner, have substrate 27, light source 28 and transmission diffusing panel 25.
And the 1st pick up camera 7 is configured in the upper end of image unit chamber 21b, and tilts towards oblique below.The 1st object detection control part 11 is incorporated in the below of the 1st pick up camera 7 in the 21b of image unit chamber, and near the 1st pick up camera 7.
Below, the method for inspection of object is described.At first, will when not lighting, illuminator 6,8 be taken among image processing part 11a, the 12a by view data α and the view data β when illuminator 6,8 is lighted from pick up camera 7,9.Then, the difference image γ that obtains behind the computing view data β subtracted image data α.When carrying out the supervision of object, carry out such action repeatedly.
By carrying out this difference processing, the emitting surface 6a after the exterior light in difference image γ around only remaining removal the, the picture of 8a.Therefore, when being the summit with pick up camera 7,9, being when not having the object of shading light in two leg-of-mutton monitor areas on base with emitting surface 6a, 8a, the picture of the emitting surface of remaining continuous straight line shape in difference image γ.
Relative therewith, when having the object of shading light in monitor area, because the part of light is blocked, so the picture of the emitting surface of difference image γ is cut to and a plurality ofly becomes discontinuous, and perhaps the length of the picture of emitting surface is short when common.The picture that detects emitting surface as image processing part 11a, 12a becomes when picture discontinuous, emitting surface shortens or the picture of emitting surface disappears, and is judged to be between vertical frame 3a, the 3b to have object, and will represents that the signal of this content sends to car control part 10.
In the cage door device of this elevator, the 1st illuminator 6 and the 1st pick up camera 7 are located on the 1st public framework 4, the 2nd illuminator 8 and the 2nd pick up camera 9 are located on the 2nd public framework 5, therefore the installation exercise of on-the-spot sensor only needs framework 4,5 is installed in that vertical frame 3a, 3b are last gets final product, and can carry out the installation exercise of sensor easily.
In addition, utilize separator of battery plates 22 that framework main body 21 internal separation are illuminator chamber 21a and image unit chamber 21b,, therefore can prevent that N/R light from entering pick up camera 7,9, improve accuracy of detection illuminator 6,8 and pick up camera 7,9 separate configuration.
In addition,, enter pick up camera 7,9, improve accuracy of detection so can prevent the light of N/R wavelength owing to shade 26 is set at the front surface of image unit chamber 21b.
In addition, because the 1st and the 2nd object detection control part 11,12 is accommodated among the 21b of image unit chamber,, with pick up camera 7,9 and 11, the 12 approaching configurations of object detection control part, can improve reliability simultaneously so can effectively utilize the space.
In addition, the 1st and the 2nd object detection control part also can be integrated.
In addition, in above-mentioned example, make looking like interruption or shortening inspected object of emitting surface by being blocked, but the method for inspection of object is not limited to this method by object.For example, also can obtain time difference image, judge whether there is the above value of predetermined value in the time difference image as the difference of up-to-date difference image and the difference image before the schedule time.In this method, if there is no object, then the time difference image is almost nil value on whole.In addition, if there is the object of motion, the part more than the predetermined value appears in the time difference image then.Therefore, if there is the above part of predetermined value, then can be judged to be and has object.According to this method, can get rid of attached to the static dust on emitting surface 6a, the 8a, only detect mobiles such as passenger efficiently.
In addition, the sliding door apparatus of clamshell doors mode has been described, but the present invention also can be applicable to the single open-door mode in above-mentioned example, the quantity of car door and stop door is not particularly limited.
In addition, in above-mentioned example, the present invention is applicable to the cage door device of elevator, but also can be applicable to landing door device.In addition, also can get off the getting on the bus of the vehicle such as gangway, train that sliding door apparatus of the present invention is applied to for example be located at building mouthful or the gangway of the platform of train.
