Embodiment Construction
[0045] The network scheduling algorithm of the CAN bus master-slave response mode protocol of the present invention, the preferred embodiment is that a plurality of nodes are included in the CAN bus network, and each node has a different node identifier, and each node in the network The communication method between them is through the master-slave response mode (or broadcast) application protocol on the CAN bus application layer, and the scheduling algorithm adopted is based on the time-triggered CAN bus scheduling algorithm.
[0046] The master node of statistical node information in the network is generated through the competition of all nodes in the network. When the network is powered on and initialized, each node broadcasts a local address, and each node compares the local identifier with the received identifier, and the local identifier of a node is the lowest. At this time, the priority of the node in the network is The highest, so the network statistics master node is ...
