Problems solved by technology

Therefore, as long as there is a failure to stop the elevator and trap people, at least two people need to go to the machine room to directly operate the mechanical parts to rescue the people, which will take a long time and easily cause secondary disasters

Embodiment Construction

[0023] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be understood that the preferred embodiments are only for illustrating the present invention, rather than limiting the protection scope of the present invention.

[0024] One of the objectives of the present invention is achieved through the following technical solutions, a fault-tolerant elevator fault-tolerant control method in a sleepy state, according to the frequency of faults, the number of simultaneous faults, the type of faults and the consequences of faults , carry out comprehensive decision-making, and output control strategies.

[0025] The invention overcomes the problem of judging the corresponding fault-tolerant state solely based on the severity of consequences caused by faults. Instead, fully consider the frequency of failures, the number of simultaneous failures and the consequences of failures, and make comprehen...

Abstract

The invention discloses a fault-tolerant control method and a system for lift failures in a state of people being trapped. The method comprises the following steps that synthetically deciding is conducted according to the happening frequencies of the failures, the number of the failures happening simultaneously, the types of the happening failures and the results caused by the happening failures, and then a control strategy is output. According to the fault-tolerant control method and the system for the lift failures in the state of people being trapped, synthetically deciding is conducted according to the severities, the happening frequencies and the number of the lift failures, and the output state of a lift is controlled according to the presented fault-tolerant control strategy, and therefore, secondary damages caused by people being trapped in the lift can be avoided effectively.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator fault-tolerant control method and system in a trapped state. Background technique [0002] Elevator is a kind of vertical carrying equipment powered by electric motor, which is used in multi-storey buildings to take people or carry goods. With the acceleration of urbanization, elevators have become an indispensable means of transportation in human life. [0003] At present, there are two main ways to obtain elevator fault information: view and process it through debugging tools in the elevator machine room, and view it on the display screen of the elevator monitoring room (generally in the security room of the community) by installing wired / wireless monitoring tools, but usually cannot deal with. There are also some additional special equipment, which store the collected information on the storage device by collecting elevator operation, maintenance and fault stat...
