The invention relates to the technical field of
data analysis, and provides a
CAN bus waveform message
analysis method, device and equipment and a medium, and the method comprises the steps: issuing an operation instruction carrying a preset operation parameter to an
oscilloscope; in response to waveform data fed back by the
oscilloscope, storing the waveform data as a message file in a preset format; analyzing and converting the message file according to the data head structural body identified by the
oscilloscope to obtain a message array; performing
time domain segmentation, normalization
processing and de-noising
processing on the data in the message array by using a Numpy
library to obtain a message
signal; and performing error frame screening on the message
signal by adopting a strategy of supplementing one after five, and performing layer-by-layer analysis on the screened message
signal based on a CAN protocol structure to obtain message analysis content. According to the invention, through the
software design of the whole process, a universal scheme is adopted from
data acquisition, storage and analysis to
signal processing and message generation, so that the analysis universality of the
CAN bus waveform message is effectively improved.
