Title:
エレベータードアに異物が挟まれていることを検出する方法、装置およびコンピュータ装置
Document Type and Number:
Japanese Patent JP7280437
Kind Code:
B2
Abstract:
A method and apparatus for detecting clamping of a foreign object (404) between elevator doors, and a computer device and a computer readable storage medium. The method comprises: when it is detected that elevator door panels (302) are completely closed, removing the door closing torque of an elevator door machine so that the elevator door panels (302) rebound; obtaining the rebound distance and rebound speed of the elevator door panels (302); and according to the bounce distance and/or rebound speed, determining whether a foreign object (404) is clamped between the elevator door panels (302). When the elevator door panels (302) are completely closed, the door closing torque of the elevator door machine is removed so that the elevator door panels (302) rebound, the encoder in the elevator door machine obtains the rebound distance and rebound speed of the elevator door panels (302) during the rebound process, and according to the rebound distance and/or rebound speed of the elevator door panels (302), determines whether a foreign object (404) is clamped between the elevator door panels (302), so as to more accurately detect whether a foreign object (404) is clamped between the elevator door panels (302), so that the elevator will not carry the object (404) during operation, thereby ensuring the safe operation of the elevator.
