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.
Information exchange based on security requirements between multiple nodes in a computer system needs to be completed by an appropriate Internet system, and the accuracy of this system dependency analysis mainly depends on the designer. The main research is the system failure based on CAN network Impact evaluation and development of the environment.At the same time, the developed IP core can realize the characteristics of CAN protocol controller and use it to establish a network composed of multiple nodes.Using analog fault insertion method to evaluate the failure of CAN bus transmission information and CAN control The impact of the device itself.The results of simulation analysis further prove that this kind of fault simulation method is feasible for studying CAN network system.
