MONITORING THE DIMENSIONS AND DEFORMATIONS OF ESCALATOR HANDRAILS BY A DIGITAL LIGHT FIELD RECORDER
(pp. 32-43)

Abstract. The problems of diagnostics of the technical support of the handrails of an escalator in a dynamic state based on an optical-electronic system (OES) of the light field (LF) are considered. A scheme for registering escalator handrails was proposed by the light field recorder. The methodology and algorithms for monitoring changes in the basic geometric parameters were developed based on the analysis of the data obtained from the light field recorder by applying various processing methods. A practical implementation of the developed algorithms on the hardware and software platform of the National Instruments company is proposed. It is shown that the accuracy of the results of determining the geometric characteristics of the handrail cloth using the proposed solutions provides the ability to diagnose and monitor the operational state of the escalator handrails.

Keywords: escalator handrail, optoelectronic system, OES, light field, LF, continuous wavelet transformation, CWT.
