AI Technical Summary
Technical Problem
Because different manufacturers produce vehicle components with different data transmission formats, how to correctly parse CAN messages in the cloud remains an urgent problem to be solved.
Method used
A CAN message parsing method is provided, which determines the bit order and byte order of the original CAN message, parses the data bit by bit according to the starting original bit number, generates a parsing file, and restores the vehicle component's custom data structure into a value that can directly represent the actual physical meaning.
Benefits of technology
It enables the parsing of CAN messages in different data formats, restores the physical meaning of sensor data, and reduces manual processing time and resource consumption.

Abstract
The embodiment of the application provides a CAN message analysis method, a server, electronic equipment and a readable storage medium, which are applied to a server and include the following steps: receiving a CAN original message sent by a vehicle; for any CAN original message, extracting original data carried in the CAN original message and converting the original data into analysis data; generating an analysis file according to the analysis data; for any CAN original message: determining a data analysis direction of an analysis bit sequence number group according to a bit sequence and a byte sequence; for any original data in the CAN original message, determining a bit length and a starting original bit sequence number of the original data, and determining a starting analysis sequence number corresponding to the original data according to the bit sequence, the byte sequence and the starting original bit sequence number; for any original data, starting from the starting analysis bit sequence number corresponding to the original data, extracting binary data corresponding to each analysis bit sequence number in the CAN original message in the data analysis direction according to the bit length, and converting the binary data into analysis data.
