Title:
SYSTEM FOR MEASURING NOISE, VIBRATION, AND RUNNING SPEED OF ELEVATOR AND ESCALATOR
Document Type and Number:
WIPO Patent Application WO/2018/151403
Kind Code:
A3
Abstract:
The present invention relates to a system for measuring noise, vibration, and running speed of an elevator, wherein the system can measure noise, vibration, running speed, etc. of an elevator through wireless communication in a state in which an operator is not in the elevator, to analyze ride quality, a running state, etc. The present invention provides a system for measuring noise, vibration, and running speed of an elevator and an escalator, the system comprising: a measurement body (31) installed on an inner floor or a step tread (21) of an elevator (10) or an escalator (20); an acceleration sensor (32) and noise sensor (33) installed in the measurement body (31); and a display device (35) allowing data obtained by the acceleration sensor (32) and noise sensor (33) to be identified outside through wireless communication.
