Elevator fault judgment method and intelligent rescue device

Abstract

The invention relates to an elevator fault judgment method and an intelligent rescue device. The intelligent rescue device comprises a master controller, a brake, a door opener and a motor. The mastercontroller is connected with an encoder. When an elevator normally runs, the encoder and the motor synchronously rotate according to the time sequence and distance, pulse signals are sent to the master controller, a flat layer inductor and an induction device which are mutually inducted are included, the induction device is fixedly arranged at the position of a well flat layer, and the flat layerinductor is arranged at the corresponding position of an elevator car. The elevator fault judgment method is further included; firstly, the sufficient condition is about whether the pulse signals ofthe encoder are sent out or not; secondly, according to the necessary condition, the flat layer inductor does not have output signals; and the elevator is in a fault state when the necessary conditionand the sufficient condition are met at the same time, and the intelligent rescue device is started for achieving automatic rescue. Under the situation that the facility or communication protocol isnot increased, through collection of encoder signals and door area signals, when the sufficient condition and the necessary condition are met, the rescue device is started, and the purpose of intelligent rescue is achieved.

Description

technical field [0001] The invention relates to a fault judging method and a corresponding rescue device in the case of an elevator fault, especially when the elevator car stops in a non-opening area, and belongs to the technical field of elevator automatic rescue. Background technique [0002] With the increasing use of elevators in modern society, people trapped in elevators have become a hot spot of public concern. [0003] On the one hand, the elevator is composed of thousands of mechanical parts and safety, electrical, control and other systems, or due to mechanical, electrical, software, power supply, etc. failures may cause the elevator to stop suddenly during operation; on the other hand, the management level In order to maintain social harmony, a series of strict elevator supervision regulations have been formulated, such as the "Special Equipment Safety Law of the People's Republic of China", "Regulations of the People's Republic of China on Special Equipment Safet...

AI Technical Summary

Problems solved by technology

The problem with this solution is that different manufacturers have different communication protocols and data processing standards, it is difficult to standardize data processing, and it is not universal; (2) The control system collects fault information: through related modules of the control system, such as programmable related systems Judging faults based on the operation status of the system, this solution depends on software drivers, and has high requirements for the environment (such as temperature and humidity, electromagnetic interference), platform (such as data storage) and management (professionals), and the platform construction and maintenance costs are expensive; (3) sensors Signal method: install contact or proximity or photoelectric sensors in the door area, drive system, shaft or related positions, check the movement of the detected parts, and send out power signals to determine the fault

The problem with this technology is that it requires additional hardware facilities and complex circuits, high cost, and increased failure points or secondary failure rates
