摘　　要：当前刨煤机CAN网络的静态调度会随着系统交换数据增加产生总线带宽资源不足状况,总线数据通讯的可靠性、安全性将受到影响,引入动态提升(DPP)调度策略以提高总线利用率,介绍了DPP调度原理。Scheduling automatic plough CAN bus with static scheduling bring lower the bus utilization, which will affect the dependability and safety of messages in system, dynamic schedule strategies can bring higher resource utilization then static ones. To solve these problems, a new DPP algorithm based on CAN bus is proposed, the principle of DPP was given.
