【摘要】 CAN总线目前已广泛地应用于分布式监测和控制系统。这就要求它既要具有很好的实时性又要具有很高的可靠性。虽然CAN协议在可靠性和实时性这两个方面分别提供了一些策略和保证,但同时两者之间又存在着矛盾并且相互制约。本文提出了利用时间触发CAN协议(TTCAN)中的一种非自动广播特性,来改善CAN协议在可靠性和实时性之间所存在的矛盾和相互制约。更多还原

【Abstract】 CAN Bus has been wildly applied in distribution and inspection and control system.This needs very high real time and very high reliability.Though CAN protocol in reliability and the two sides of real time difference have offered some strategy and guarantee,but at the same time,again have contradiction and restrict mutually between two.This paper has put forward to use a kind of non-automatic broadcasting property in TTCAN protocol to improve CAN protocol in reliability and real time between the contradictory and mutual restriction.更多还原
