摘　　要：时间触发协议具有精度高、实时性好、灵活应用的特点,在现代工业总线领域的应用逐渐增多。FlexRay是一种典型的时间触发协议总线,它既考虑了时间同步、通信调度和容错机制,又考虑了传输速度、安全性、操作灵活性、实时、分布式智能、网络拓扑等,而FlexRay总线的参数设计是FlexRay总线的应用难点,大量的网络协议参数以及相对应的关联计算与约束条件,使得FlexRay的应用较为复杂。设计一款针对FlexRay应用的参数设计与管理软件,从参数与时隙调度配置、组网设置、通信状态监测方面开展设计,有效简化了FlexRay总线的应用难度。Time triggered protocol had the characteristics of high precision,good real-time and flexible application,and its application in the field of modern industrial bus has been increasing gradually.FlexRay was a typical time triggered protocol bus,which not only considered time synchronization,communication scheduling and fault tolerance mechanism,but also considered transmission speed,security,operational flexibility,real-time,distributed intelligence,network topology,etc.The parameter design of FlexRay bus was the application difficulty,a large number of network protocol parameters,and corresponding associated calculation and constraints conditions made the application of FlexRay more complex.It was designed that a parameter design and management software for FlexRay application.Its designs parameters and time slot scheduling configuration,networking settings and communication status monitoring effectively simplified the application difficulty of FlexRay bus.
