Title:
ELEVATOR FAULT RESCUE SYSTEM AND ELEVATOR
Document Type and Number:
WIPO Patent Application WO/2020/238079
Kind Code:
A1
Abstract:
An elevator fault rescue system and an elevator, the system comprising: an elevator controller, which is used for determining whether an elevator has broken down, switching the elevator to an intelligent rescue state if the elevator has broken down and controlling the elevator to run normally if the elevator has not broken down; a magnetic grid ruler sensor, which is used for collecting elevator running speed signals and elevator position signals and transmitting same to the elevator controller; and an encoder, which is used for collecting the elevator running speed signals. The elevator controller is further used for the one-time determination of the speed measured by the magnetic grid ruler sensor and the encoder. When the measured speed is greater than a set value, the elevator is controlled to enter a secondary rescue state; and when the speed measured by the magnetic grid ruler sensor and the encoder is not greater than the set value, the elevator is controlled to run to a floor. The present elevator fault rescue system may quickly respond, switch and control when the elevator encounters a power supply system failure or an elevator soft failure. A fault leveling device intelligently determines the running speed to a floor position and opens a car door and hall door to allow passengers to safely get out of the elevator, thereby greatly reducing the incidence of trapped people.
