[0025] The data processing module 2 is connected to the monitoring module 1. Specifically, the data processing module 2 includes an A\D converter 17 and a microprocessor 18. The A\D converter 17 and the microprocessor 18 are arranged in the elevator car. The A\D converter 17 is connected to all sensors of the monitoring module 1 to convert the analog signals of the sensors into digital signals. By connecting the A\D converter 17 to all sensors of the monitoring module 1, the system cost can be reduced and it is convenient for large-scale promotion and application. The A\D converter 17 is connected to the microprocessor 18 to transmit the digital signal to the microprocessor 18. More specifically, the microprocessor 18 can use an STM32 single-chip microcomputer. After receiving the digital signal, the microprocessor 18 first performs a wavelet transform, then performs feature extraction, and finally collects the data in the SVM classifier of the microprocessor 18. The SVM classifier performs data analysis. Through data analysis, the elevator state can be divided into two categories: normal state and fault state. When the elevator is in a normal state, the elevator continues to maintain the original standby or running or energy-saving state.
