The Application of TCP Protocol in CAN Network Data Flow Transmission
DING Junfeng
Abstract：In response to the demand for data flow transmission through CAN network for fault recording and remote upgrading in mining control systems,as well as the slow and inefficient data flow transmission caused by short frame structure and lack of efficient transmission control protocol on CAN bus,a transmission method using Ethernet TCP protocol in CAN network was proposed.The relative address technology,sliding window technology,breakpoint continuation technology,and other technologies were applied in the Ethernet TCP protocol to the CAN network,and a data flow transmission method was designed suitable for the CAN network.The experimental results showed that this method could achieve fast and reliable transmission of data flows,improve the transmission efficiency of data flows.Compared to traditional transmission methods,this method has the advantages of high frame utilization,high bus utilization,and high retransmission efficiency,making it suitable for CAN networks with large file interactions.
