基于 CAN 网络系统的故障影响研究

基于计算机系统多个节点之间进行安全性要求严格的信息交换需经合适的互连网系统来完成的．而这种系统相关性分析的准确性主要取决于设计者．主要研究了基于CAN网络系统故障影响评价而开发的环境．同时被开发的IP核能实现CAN协议控制器特性，并利用它建立了由多个节点组成的网络．采用基于模拟的故障插入方法评价故障对CAN总线传输信息和CAN控制器本身的影响．仿真分析结果进一步证明：此种故障仿真方法对于研究CAN网络系统是可行的．

Study of failure impact based on the CAN network system

The strict exchange of information with security requirements between multiple nodes based on computer system has to be carried out via the appropriate Internet system.The accuracy of the correlation analysis of this system depends on the designer.This paper mainly studies the environment which is developed based on the assessment of failure impact on the CAN network system.Meanwhile an IP core is developed to achieve the CAN protocol controller features and used to establish a network of multiple nodes.A fault insertion method based on simulation is used to evaluate the failure impact on the CAN bus and CAN controller itself.The simulation results further show that such a fault simulation method is feasible for the study of the CAN network system.
