摘要
Abstract
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 flexibly specified as required. Once the emulational comparison be-tween the original CANbus static priority scheduling strategy and this new dynamic strategy is proceeded,the feasibility of the latter approach would be verified. The deterministic of communication would be guaranteed as well.关键词
