Generally, when the escalator is checked, due to the structure of the escalator, after the escalator is installed, the inner parts of the upper and lower mechanical chambers and the middle step moving channel are parts which cannot be checked by maintenance personnel on a daily basis, and only the maintenance personnel can open the upper and lower decks of the escalator to enter the upper and lower mechanical chambers for checking, and the space is too narrow, so that comprehensive checking is difficult, and precise checking operation is difficult.

In the moving passage of the middle step of the escalator, since the installation is completed, the inspection operation cannot be performed due to the space relationship, and if the detachment of the step is required to perform the inspection, a large amount of time is required, so that the regular spot inspection operation performed every month cannot be performed on the important safety switch and the important part in the moving passage of the step, and thus, the monitoring of the important position of the escalator is difficult to be realized. Although some parts inside the escalator can confirm the state of the components in a visual observation mode by opening the deck of the mechanical room, the reliability of the detection result is low; on the other hand, even if professional equipment can be used for carrying out comprehensive and precise inspection after the escalator steps are disassembled, the defects of long period, poor timeliness and the like exist, and the normal operation of the escalator is influenced.
