Analysis for Real-time Performance of Improved CAN Protocol
摘要
Abstract
As CAN (Controller Atea Network) is increasingly used in real-time control systems,the teal-time performance of CAN bus has a fatal effect on safety and dependency of systems. In this paper .based on the systematic analysis of CAN protocol, provide an improved CAN protocol which can reduce the number of identifiers and extend data bytes. Analyze utilization rate of frame of the improved protocol and apply it to a message set to calculate the worst case response time. The results of experiments indicate that, the improved CAN protocol can provide a higher utilization rate of frame while reducing the worst-case response time, thereby improving the real-time communication based on CAN bus.关键词
