随着导弹发射控制系统的功能愈发复杂,传统CAN总线网络在通讯速率、实时性上已愈发难以满足未来武器系统的信息化要求。针对这一现状,提供了一种将高实时性汽车总线FlexRay运用在导弹发射控制系统中的设计,重点阐述了VxWorks系统下FlexRay总线控制器驱动以及上层应用程序的设计,研究分析了最坏响应时间。测试结果表明,FlexRay总线可以满足导弹发射控制系统的性能和可靠性要求,为今后在武器系统上的具体应用打下了理论基础。

With functions of the missile launch-control systems being increasingly compound,the traditional CAN bus has become difficult to meet the informatizing requirements of future weapon systems in communication rate and real time capability.In terms of the current circumstance,a design that uses the FlexRay,a vehicle bus of high real time capability,in the missile launch-control systems is proposed in this paper.Furthermore,the design of the drive of FlexRay control unit and the upper application under the VxWorks system has been mainly demonstrated,and the worst-case response time has been studied and analyzed as well.The test results show that the requirements of performance and reliability of the missile launch-control system can be fulfilled by the FlexRay bus,which set a solid theoretical foundation for its certain application in weapon systems in the future.
