【摘要】 针对航空领域对总线的要求具有高安全性、高稳定性、高实时性等特点,在学习与研究传统的IEEE-1394、IEEE-1394a和IEEE-1394b总线的基础上,提出并验证线缆环境下的物理环形拓扑结构中,结合各节点的安全等级,通过软件合理的控制环断开点的具体位置,重新规划系统的拓扑结构,使得1394总线在网络安全性、传输实时性、稳定性等方面的性能有很大提升。更多还原

【Abstract】 For the requirements for buses with high security, high stability, high real-time characteristics in the aviation field, by studying the traditional IEEE-1394, IEEE-1394 a and IEEE-1394 b buses, proposes and verifies that the physical ring topology in the cable environment,combined with the security level of each node, redefines the topology of the system through the reasonable control of the ring break point,makes the 1394 bus in the network security, transmission real-time, stability and other aspects of performance compared to now greatly improved.更多还原
