When maintenance model data 31 (a reference value) and the data of the output signal obtained in mainteinance repair be compared, determine maintenance inspection
Whether output signal when repairing is abnormal.In the case where output signal exception when mainteinance repair, it is meant that in escalator 1
Step driving portion 200 generates certain exception.
As abnormal detection example, such as there is a situation where as follows: in step front vehicle wheel 220 and step rear wheel 230
Any one or multiple wheels generate the lateral shift being detached from from scheduled track.In this case, step front vehicle wheel 220
Or the part that step rear wheel 230 is contacted with shape changing detection portion 40 becomes a part.Therefore, even if step front vehicle wheel 220 or
Person's step rear wheel 230 by shape changing detection portion 40, the deformation quantity in shape changing detection portion 40 also than it is usual when it is small, output signal also becomes
It is small.As other examples of abnormality detection, such as there is a situation where as follows: times of step front vehicle wheel 220 and step rear wheel 230
Anticipate one or more wheel breakage.In this case, the output signal from shape changing detection portion 40 becomes smaller or detects completely
Less than.When damaged wheel generates defect as protrusion, it is also possible to generate the feelings that output signal abruptly becomes larger
Condition.
I.e., when passing through in shape changing detection portion 40 when normal wheel, the output signal in shape changing detection portion 40 is with substantially permanent
Fixed intensity passage.Abnormal be used as of wheel is detected from constant intensity convex peak value outstanding or recessed peak value.When in this way
Peak value and a reference value on there are output letters when in the case where deviation more than preset threshold value, being determined as mainteinance repair
Number exception.Threshold value is for example found out according to the specification value etc. of escalator 1.Output signal of the signal processing part 22 when mainteinance repair
It is judged to generating certain exception in the step driving portion 200 of escalator 1 in the case where exception.

If escalator 1 is made to work, step front vehicle wheel 220 and step rear wheel 230 are advanced along guide rail 300.At this point,
The deformation of predetermined amount is generated in guide rail 300.If step front vehicle wheel 220 and step rear wheel 230 are respectively on changing sensor 40a
Pass through, is then transferred to changing sensor 40a in the deformation that guide rail 300 generates, the deformation of predetermined amount is detected as output signal.
In addition, changing sensor 40a is for example also possible to use the semiconductor bodily form of piezoelectric element to become measuring instrument etc..
Also, changing sensor 40a is set to the upper surface of guide rail 300, but also can be set in lower surface.As a result, can
It is enough to inhibit to lead to changing sensor 40a damage this case because of step wheel etc..In this way, changing sensor 40a (shape changing detection
Portion 40) interarea in guide rail 300, i.e. either one or two of upper surface or lower surface can be set.But it is produced because of step wheel etc.
The deformation quantity of raw guide rail 300 is larger in the upper surface of guide rail 300.Therefore, guide rail 300 is set to by changing sensor 40a
Upper surface, output signal becomes larger, and is able to detect more small deformation.
