Abstract

The invention discloses a system for acquiring opening and closing information of an elevator cage door. The system comprises an acceleration module which is connected with a single-chip MCU through data and is used for acquiring acceleration information of the cage door, completing acquisition of original data once within certain time and carrying out sum averaging on data of a set number of points to obtain a sum average serving as a sampling point; a Flash chip which is connected with the single-chip MCU through data and is used for storing statistical data of an elevator, a real-time clock management unit which is connected with the single-chip MCU through data and is used for supplying a clock interface for the system, and the single-chip MCU for analyzing opening and closing information of the elevator cage door according to the acceleration information, including: opening (closing) the door: when a negative (positive) directional amplitude value of the sampling point exceeds a door opening (closing) threshed value, calibrating the sampling point as negative (positive) directional acceleration gradual increase, then judging whether the positive (negative) directional amplitude value of the sampling point exceeds the door opening (closing) threshed value, and if the positive (negative) directional amplitude value of the sampling point exceeds the door opening (closing) threshed value, judging that the cage door is in a door opening (closing) state.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a system for collecting switch information of elevator car doors. 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 ...
