AI Technical Summary

Technical Problem

Existing elevator micro-motion leveling detection systems have a large number of detection elements and high costs, resulting in high elevator production, installation and maintenance costs, as well as a cumbersome component layout.

Method used

An integrated leveling sensor is used, which integrates detection elements for edge detection, leveling zone judgment, and car micro-motion zone judgment. Combined with the shielding plate and groove design on the leveling sign component, the car position can be accurately detected and micro-motion leveling control can be achieved by differentiating the signals of the shielded and unshielded detection elements.

Benefits of technology

The number of components in the detection system has been reduced, production and installation costs have been lowered, component layout has been simplified, the accuracy and safety of micro-motion leveling control have been improved, and it is highly adaptable and easy to promote in the industry.

Abstract

The invention discloses an elevator micro-motion leveling detection device and method. The problems that an existing elevator micro-motion leveling detection device is large in number of parts and high in cost are solved. The device comprises a leveling sensor and a leveling mark component in a hoistway, the leveling sensor is integrated with a plurality of detection elements for achieving leveling area edge detection, leveling area judgment and micro-motion area judgment, and different electric signals are output when all the elements are shielded and not shielded; the flat layer marking part is provided with an upper micro-motion area, a non-micro-motion area and a lower micro-motion area in the vertical direction, shielding pieces matched with the micro-motion area judging element are arranged on the flat layer marking part, an upper groove and a lower groove which are different in vertical length are formed by the adjacent shielding pieces, and the flat layer marking part is further provided with an edge groove matched with the edge detecting element. Detection parts are simplified, the cost is reduced, the position of the lift car can be accurately recognized, reliable signals are provided for micro-motion leveling, door area edge detection can be achieved, the elevator running safety is improved, and the device is matched with an existing elevator control system.
