为满足武器系统日益增涨的数据量及可靠性需求,本文设计了一种基于CPCI架构的FlexRay总线仿真测试系统,系统硬件由仿真板、侦听板和适配板等组成;通过参数分类、参数模糊设置等方法,实现了多节点在不同传输速率和网络拓扑下的70余种协议参数的仿真优化。实验表明,该系统能够高效的对FlexRay总线参数进行配置并仿真,大大降低了FlexRay总线的设计难度,减小了设计风险,提高了总线故障定位的准确度。

Based on the CPCI architecture, the FlexRay bus simulation test system is designed to meet the requirement of increasing data and reliability for weapon system. The test system consists of the simulation board, the monitoring board and the adaptive board. It can realize the simulation optimization of 70 kinds of protocol parameters of multiple nodes under different transmission rate and network topology by means of parameter classification and parameter fuzzy setting. It greatly decreases the design difficulty of FlexRay bus, reduces the design risk and improves the accuracy of fault location.
