分布式环形网络测发控系统故障恢复时间模型

Research on the Recovery Time of Ring Networked Test and Firing Control System

测发控系统是武器系统中的重要组成部分。提出了一种基于分布式冗余协议(DRP)的测发控系统实现设想,避免了主从式网络中风险高度集中在主站的问题。在对DRP分布式环形网络冗余协议故障诊断和恢复机理进行详细分析的基础上,建立DRP故障恢复时间模型,根据该模型和控制系统采样周期的关系,分别进行环形网络化控制系统丢包概率分析。

The test and firing control system is an important component of a weapon system. A dis- tributed redundancy protocol （DRP） distinguished with master and slave redundancy protocol is proposed to avoid the problem of risk focused on the master station. Based on the analysis of the fault detection and recovery mechanism of DRP, a model of DRP fault detection and recovery is established. The data packet dropout model of ring networked control systems is created according to this model and the communication cycle.
