The invention relates to an elevator passenger scream detection method based on multi-dimensional features and a system. The method comprises the following steps of a, collecting acceleration data and audio data of the operation of an elevator, and preprocessing the collected data; b, analyzing the acceleration data to judge whether the operation of the elevator is abnormal or not, and if so, extracting the audio characteristics of the audio data; and c, analyzing the audio characteristics to judge whether a passenger squeal phenomenon occurs in the elevator or not, and if yes, sending out an alarm signal. According to the elevator passenger squeal detection method based on the multi-dimensional features and the system, and elevator safety accidents can be reported in time through the method of detecting the scream of the passenger, so that the safety of the passenger is guaranteed.
