Abstract

The invention provides a CAN message analysis method and device and a terminal. The method comprises the following steps: receiving a CAN message; obtaining a target parameter configuration table item matched with the CAN message from a configured parameter configuration table; analyzing a target original parameter value from the CAN message according to parameter indication information in the target parameter configuration table item; and according to national standard parameter mapping information in the target parameter configuration table item, mapping the target original parameter value into a target national standard parameter value meeting a national standard definition. By applying the method, the terminal can automatically analyze the original parameter value of the CAN signal carried in the CAN message and automatically map the original parameter value into the national standard parameter value under the national standard definition, and because the national standard parameter value meets the national standard definition, the national standard parameter value can be directly applied to a national platform.

Description

technical field [0001] The present application relates to the field of CAN technology, in particular to a CAN message analysis method, device and terminal. Background technique [0002] CAN (Controller Area Network, Controller Area Network) bus, as a standard bus for automotive computer control systems and embedded industrial control LANs, is widely used in automotive communication systems. Nodes on the CAN bus, such as the engine, gearbox, steering and other components of the car, encapsulate CAN signals in messages (subsequently referred to as CAN messages), and transmit CAN messages to the outside through the CAN bus, such as terminals to achieve communication , based on this, in the fields of automotive electronic product development, automotive decoding, etc., it is often necessary to analyze CAN messages. [0003] In the prior art, there are existing implementation methods that enable the terminal to automatically parse the CAN message and obtain the original paramete...
