Elevator system provided with elevator wireless communication system with redundant fault-tolerant function

Abstract

The invention discloses an elevator system provided an elevator wireless communication system with a redundant fault-tolerant function. The elevator system comprises an elevator control cabinet, a traction system, an elevator car and the elevator wireless communication system. The wireless communication system is used for safe circuit and interaction information communication between the elevator car and the control cabinet, and is composed of at least two different types of wireless communication modules with different abnormal or failure factors. When a communication circuit of a certain type of communication module is abnormal or fails, communication circuits borne by other wireless communication modules which are not sensitive to the abnormal or failure factors of the type are in a normal work state, and safe circuit faults and communication circuit faults caused by abnormity or failures because of single type wireless communication limitation are greatly reduced. The elevator system has extremely high reliability and robustness, operation quality of no-cable elevators and light cable elevators is greatly improved, and development and popularization of the no-cable elevators and the light cable elevators are promoted.

Description

technical field [0001] The invention relates to the technical field of elevator communication, in particular to an elevator system with a redundant fault-tolerant elevator wireless communication system. Background technique [0002] At present, most elevators use accompanying cables as the signal and energy channels of the car. As the floor increases, the weight of the accompanying cable increases the burden on the elevator and increases the strength requirements of the accompanying cable; the accompanying cable may also be in contact with or entangled with the equipment in the shaft; at the same time, the growth of the accompanying cable also increases the difficulty of installation and operation of the elevator. Power loss and maintenance costs. [0003] In addition, subject to the constraints of guide rail brackets and switch brackets, the accompanying cables of sightseeing elevators also affect the design of sightseeing elevators. Therefore, cable-free elevators have be...
