The invention belongs to the technical field of charging piles, and discloses a charging
pile CAN bus baud rate
adaptive method,
system and device and a storage medium. Comprising the following steps that internal CAN communication is used as a use object, a core node CMU evaluates the stability of a CAN
communication link and dynamically adjusts the
baud rate to optimize the communication performance by analyzing the accuracy of received frames,
adaptive matching of the
baud rate is carried out according to the accuracy of received messages for newly added nodes, and the communication performance is optimized. The communication efficiency and quality of each node in the CAN network are ensured, when the
communication quality is reduced, the baud rate is reduced, errors in
data transmission are reduced, and the accuracy and integrity of data are ensured; under the condition that the
communication quality is good, the baud rate is improved, so that the
data transmission speed is accelerated. Therefore, the communication efficiency can be improved, the time and resources required for
data transmission can be reduced, and the technical problems that in the prior art, existing fixed-rate communication is prone to being interfered in a changeable application environment, and the communication efficiency is low are solved.
