摘　　要：为提高弹上点火系统的可靠性和抗干扰能力,针对弹上点火系统承担的功能和时序复杂化,点火部件呈分布式布局现状,提出一种基于FlexRay总线设计的弹上点火控制方法。将FlexRay总线技术的优势和点火控制系统的可靠性需求进行了对比分析,设计了点火控制电路,测试结果表明,FlexRay总线可以满足弹上分布式点火控制系统的性能和可靠性需求,简化了弹上点火系统的通信链路,进一步提升了点火控制系统的抗干扰能力。To improve the reliability and capacity of resisting disturbance in the ignition system of missile,based on the state that more functions,complex timing sequence and distributed initiators increasing,the paper proposes a new design,on which the FlexRay bus applied,and contrasts the advantages of FlexRay bus and the reliability requirement of distributed ignition control system.Experimental results show that the ignition circuit is reliable,and the communication control strategy can be simplified,and the anti-jamming capacity of ignition system in missile can be enhanced.
