System for collecting motion information of lift car

Abstract

The invention discloses a system for collecting the motion information of a lift car. The system for collecting the motion information of the lift car comprises an acceleration module, a Flash chip, a real-time clock management unit and a single-chip microcomputer MCU, wherein the acceleration module completes collection of original data once within a certain time and sum and average the data of a specified number of points, and the average is used as a sample point; the Flash chip stores the statistics data of a lift; the real-time clock management unit provides a clock interface for the system; and the single-chip microcomputer MCU analyzes the motion information of the lift car according to acceleration information. According to analysis of the single-chip microcomputer MCU, during upward (downward) movement, when the negative (positive) amplitude value of the sample point exceeds the upward (downward) movement threshold, negative (positive) acceleration gradual increase is determined, and the lift moves upwards (downwards) and accelerates at the moment; then, whether the negative (positive) amplitude value of the sample point exceeds the upward (downward) movement threshold or not is judged, if yes, positive (negative) acceleration gradual change is determined, and the lift moves upward (downward) and decelerates at the moment; and finally, whether the lift meets a stopping condition or not is judged, and if yes, one upward (downward) movement process is ended.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a system for collecting motion information of an elevator car. Background technique [0002] In recent years, with the rapid development of the elevator industry, elevator accidents have increased. In addition to problems in the design, installation and use of elevator products, elevator maintenance defects are also the main cause of accidents. According to national regulations, elevator maintenance units should have special quarterly maintenance, semi-annual maintenance and annual maintenance. In the existing maintenance system, maintenance personnel cannot provide targeted maintenance according to the frequency of use or failure rate of each elevator, and due to the vicious competition in the maintenance industry, "maintenance on paper" often occurs during the maintenance process. ", "Not present if there is no accident". Contents of the invention [0003] In order to sol...
