When a cutting amount of the deepest concave portion extracted by the deepest concave portion extracting unit is not smaller than apredeterminedthresholdwhichisavalueregardedas occurrence of deterioration, the personal computer 10 performs control of processing for outputting a driving signal to the drive contrel portion 12 for the radiation unit 8 so as te allow the radiation to be transmitted through the moving handrail 1.
[0024]
In addition, the personal computer 10 extracts a deepest concaveportioncolor tonedeviationwhichisadeviationbetween a color tone of the deepest concave portion extracted by the deepest concave portion extracting unit and the predetermined color tone of the surface of the new moving handrail when the cutting amount of the deepest concave portion is smaller than the predetermined threshold.

[0026]
Further, the personal computer 10 extracts a highest convex portion color tonedeviationwhichisadeviationbetween a color tone of the highest convex portion extracted by the highest convex portion extracting unit and the predetermined color tone of the surface of the new moving handrail when the swelling amount of the highest convex portion is smaller than the aforementioned predetermined threshold. When the highest convex portion color tone deviation exceeds a predetermined threshold which is a value regarded as occurrence of deterioration, the personal computer 10 performs control of processing for cutputting a driving signal to the drive control portion 12 for the radiation unit 8 so as to allow the radiation to be transmitted through the moving handrail 1.
[0027]
The control of processing by which the embodiment configured thus is characterized will be described below.
[0028]
That is, images of the surface of the moving handrail 1 in a state in which the moving handrail 1 is moving due to the running of the passenger conveyor are taken by the first cameras 2 and 3 in order to diagnose deterioration of the moving handrail 1. The taken images are imported to the image import portion © and further transmitted from the image import portion
Stothepersonal computer 10. Thepersonal computer 10extracts a deviation between a color tone in the surface of the moving handrail 1 chiefly obtained from the images taken by the first cameras 2 and 3 and a predetermined color tone in the surface of a newmoving handrail. When the extracted deviation exceeds apredeterminedthresholdwhichisavalue regardedasoccurrence of deterioration, the personal computer 10 performs arithmetic operation for identifying the position of the moving handrail 1 in the images taken by the first cameras 2 and 3 at that time.
In this arithmetic operation, for example, a joint portion of the moving handrail 1 formed to be endless is set as a reference position, andadistance fromthe reference position is obtained so as to identify the position of deterioration in the moving handrail 1.
[0029]
In the aforementioned state, as soon as the identified position of the moving handrail 1 which is moving reaches a position where the radiation unit 8 is placed, the personal computer 10 outputs edriving signal tothedrive control portion 12 for the radiation unit 8 so as to allow the radiation to be transmitted through the moving handrail 1. Thus, in the identified position of the moving handrail 1 regarded as occurrence of deterioration, theradiation, that is, theX-rays, is emitted from the radiation unit 8 toward the moving handrail 1, so that a radiographic image of the moving handrail 1 is taken by the second camera 7. The radiographic image taken by the second camera 7 is transmitted to the personal computer through the image import portion 9. Processing for displaying the radiographic image is controlled by the personal computer 10 so that the radiographic image is displayed on the monitor 11.
[0030]
The control of processing by which the embodiment is characterized has been described above. Thedetails of control including various kinds of processings to be performed by the personal computer 10 will be described below with reference to Fig. 2.
[0031]
Based on the taken images transmitted from the first cameras 2 and 3 through the image import portion 9, the personal computer 10 integrates and synthesizes movie frames of the first cameras 2 and 3 using the 3D image synthesizing unit so as to synthesize a 3D image of the moving handrail 1 (Step S51).
[0032]
Next, the personal computer 10 uses the deepest concave portion extracting unit to perform processing for extracting a deepest concave portion in the aforementioned 3D image by comparison between one section of the 3D image and another (Step
S52).
[0033]
Next, thepersonal computer l0 calculates acuttingamount of the extracted deepest concave portion, which indicates the depth of the extracted deepest concave portion from the average coordinates of all the sections, and determines whether or not the cutting amount is at least a predetermined threshold which is a value regarded as occurrence of deterioration (Step S53).
[0034]
When the determination concludes that the cutting amount is not smaller than the threshold, the personal computer 10 obtains thedistanceof the deepest concaveportion, forexample, fromthe joint portion of themoving handrail 1 so as to identify the position of the deepest concave portion (Step $10). Next, the personal computer 10 sets a deterioration flag in the identified position of the deepest concave portion (Step S11).
[0035]
When the position of the deterioration flag reaches the position where the radiation unit 8 is placed in accordance with the movement of themoving handrail 1, the personal computer outputs a driving signal to the drive control portion 12 soastoemit theradiation, thatis, theX-rays fromthe radiation generator 4 of the radiation unit 8 toward the moving handrail 1. The radiation transmitted through the moving handrail 1 moves via the fluorescent screen 5 and the reflecting mirror 6 and is photographed as a radiographic image by the second camera 7. Theradiographic image istransmittedtothepersonal computer 10 through the image import portion 9. Processing for displaying the radiographic image is controlled by the personal computer 10 so that the radiographic image is displayed on the monitor 11 (Step S12).
[0036]
When the determination in Step $3 concludes that the cutting amount of the deepest concave portion extracted by the deepest concave portionextractingunit of the personal computer 10 is smaller than the predetermined threshold, the perscnal computer 10 extracts a deepest concave portion color tone deviationwhichisadeviationbetweenacolor tone of the deepest concave portion and the predetermined color tone of the surface of the new moving handrail 1 (Step S54).
[0037]
Next, the personal computer 10 determines whether or not the extracted deepest concave portion color tone deviation is at most a predetermined threshold which is a value regarded as occurrence of deterioration (Step 85).
[0038]
When the determination in Step S5 concludes that the deepest concave portion color tone deviation exceeds the threshold, processing in the aforementioned Steps S10, S11 and 512 is performed so that the radiographic image is displayed on the monitor 11.
[0039]
On the other hand, when the determination in Step S55 concludes that the deepest concave portion color tone deviation is not larger than the threshold, the personal computer 10 uses the highest convexportionextractingunit toperformprocessing for extracting a highest convex portion in the aforementioned 3D image by comparison between one section of the 3D image and another (Step 56).
[0040]
Next, the personal computer 10 calculates a swelling amount of the extracted highest convex portion, which indicates the height of the extracted highest convex portion from the average coordinates of all the sections, and determines whether or not the swelling amount is at least a predetermined threshold which is a value regarded as occurrence of deterioration (Step
S7).
[0041]
When the determination in Step S87 concludes that the swelling amount is not smaller than the threshold, the personal computer l0identifiesthepositionof thehighest convexportion (Step 810). Processing in the aforementioned Steps S11 and
S12 is performed so that the radiographic image is displayed on the monitor 11.
[0042]
On the other hand, when the determination in Step S7 concludes that the swelling amount of the highest convex portion is smaller than the threshold, the personal computer 10 extracts a highest convex portion color tone deviation which is a deviation between a color tone of the highest convex portion and the predetermined color tone of the surface of the new moving handrail {Step S8).
[0043]
Next, the personal computer 10 determines whether or not the extracted highest convex portion color tone deviation is at most a predetermined threshold which is a value regarded as occurrence of deterioration (Step S59). [C044]
When the determination in Step S9 concludes that the highest convex portion color tone deviation exceeds the threshold, processing in the aforementioned Steps S10, S11 and
S512 is performed so that the radiographic image is displayed on the monitor 11.
[0045]
On the other hand, when the determination in Step S9 concludes that the highest convex portion color tone deviation is not larger than the threshold, the moving handrail 1 is diagnosed as not deteriorated, and the diagnosis of deterioration in the moving handrail 1 is terminated.
[0046]
According to the embodiment in which deterioration in the moving handrail 1 is diagnosed in the aforementioned configuration, it is possible to perform not only the diagnosis of deterioration of the moving handrail 1 based on the cutting amount of the moving handrail 1 and the diagnosis of deterioration of the moving handrail 1 based on the swelling amount of the moving handrail 1 but also the diagnosis of deterioration of the moving handrail 1 based on the change of thecolortoneinthesurfaceof themovinghandraill. According to the embodiment, it 1s therefore possible to perform the diagnosis of deterioration of the moving handrail 1 with high accuracy and perform inspection and replacement of the moving handrail 1 at a proper time. Thus, it is possible to provide a highly reliable apparatus for diagnosing deterioration of a moving handrail in a passenger conveyor.
[0047]
In addition, the area to perform the diagnosis of deterioration using X-rays can be narrowed in accordance with the change of the color tone in the surface of themoving handrail 1. It is therefore possible to improve the safety of a worker handling the X-rays and it is also possible to reduce the running cost. Further, the place where the diagnosis of deterioration should be performed based on X-ray images is identified. It isthereforepossible tomakedeterminationwithhigher accuracy than in the procedure in which X-ray images of the whole moving handrail are taken anda position of deteriorationis identified fromthe huge volume of X~ray images for the sake of the diagnosis of deterioration.
