[0077] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and together with the embodiments of the present invention are used to explain the principle of the present invention and are not intended to limit the scope of the present invention.
[0078] The CAN bus communication protocol is a bus protocol based on the response mechanism. The status of each node in the bus system is equal, and there is no master-slave distinction. When the bus is idle, each node can send data. When a node seizes the bus as a transmitter, all other nodes automatically become receivers, and each node in the system can receive the data message sent by the sending station; when there are multiple When two nodes try to send at the same time, the priority of their data frames determines which node has higher priority. The node with a higher priority data fram...
