The embodiment of the invention discloses an elevator data acquisition method and device. The method comprises the following steps: obtaining acquired multimedia data through communication connection among multimedia data acquisition equipment configured in an elevator, and carrying out video identification and/or audio analysis according to the multimedia data to determine the performance of the elevator. Through the adoption of the technical scheme, whether the performance of the elevator reaches the standard or not can be determined in real time, a parameter which does not reach the performance standard of the elevator can be regulated correspondingly to increase the comfort level of the elevator. Meanwhile, different detection instruments are not needed to be used to detect the properties of the elevator one by one, so that the detection process is simplified, a great quantity of manpower and material resources are saved, the elevator data acquisition efficiency and the elevator performance analysis efficiency are improved.
