Abstract: In order to solve the problem of the difficult in travelling cable troubleshooting, cable fatigue fracture and faults in the elevator control system timely detect and troubleshoot, the elevator control system was studied, the wireless communication was applied in car communication between the host controller of elevator and the car controller. The no traveling cable in the elevator was a chieved. In the design of wireless elevator safety loop, four relays were used to connect the computer room safety loop to the car safety loop. In the hardware circuit design, the ZigBee wireless module with STM32W108 chip as the core was used as the communication module. In the wireless elevator control system, a set of intelligent fault diagnosis system based on expert system was also integrated. The experimental test was carried out by building an experimental platform. The experimental results show that the wireless communication of the system is normal and the fault diagnosis of the security loop is unmistakable.
