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.
