基于量子框架(QF)的多总线交换机的设计

The Design of Multiple-bus Switch Based-on Quantum Framework(QF)

汽车多总线技术的飞速发展虽然很大程度上提升了汽车性能,但却不利于汽车内部不同网络系统开放性,系统的扩展及裁剪都比较困难。文章提出基于量子框架来设计多总线交换机。首先介绍了量子框架的基本特点及其运行机制,然后分析了基于CAN/LIN/FlexRay的多总线交换机的工作过程。建立了一个基于量子框架的多总线交换机状态机模型,将整个系统分解为3个相互独立的活动对象,运行在量子框架提供的软件总线上,顺利实现不同网络的数据通信,提高了软件设计效率以及系统的可维护性。

The rapid development of multiple-bus technology has raised the vehicle performance greatly, but it baffled the system opening in the vehicle internal different buses and brought the difficulties of expanding and cutting off the system functions. Firstly, It said the design of multiple-Bus Switch Based-on Quantum Framework （QF） which introduced the essential features and its movement mechanism on the QF, then analyzed the process of the CAN/LIN/FlexRay Multiple-Bus .Finally, it established the state machine model based on the Quantum Framework （QF） which decomposed the system into three independent active objects mutually that ran in the software bus supplied by QF, realizing the communication between different buses. The application of Quantum Framework （QF） technology in embedded system can improve the flexibility of system and enhance the efficiency as well as the system maintainability.
