In the system requiring comparatively higher deterministic of communication, static priority scheduling algorithm may bring about that the nodes of lower priority fail to access to the bus within a long period,which leads to a result that some data couldn’ t be sent. To overcome this defect,a new dynamic priority scheduling strategy is put forward:Traverse each node periodically and then adjust the priority of each node dynamically as per its bus arbitrary frequency. In the meantime, the pre-value interval and threshold of each node could be f...
