摘　　要：武器系统采用分布式控制体系结构后需解决好通信时延的问题,通过对分布式火控系统通信时延的分析,说明了在火控系统中宜采用固定时延的通信方式,揭示了对随机时延采用缓冲等待方法的实质。提出了利用采样的周期信息实现时钟同步的方法,这些结论和方法对其他分布式控制系统也具有参考价值。Communication time delay must be well arranged when distributed system configuration is used in weapon system. Through analysis of communication characteristic about distributed firing control system, the reason why communication with constant time delay should be first adopted in firing control system is analyzed, Essence of buffer awaiting method adopted in stochastic time delay communication is declared. Then clock synchronization method utilizing sampling periodicity is proposed. Conclusions and methods in this paper are also valuable to other distributed control system.
