摘要
为满足舰船动力网络控制系统的实时性、时间确定性和时间同步的要求,本文对现有的网络时间协议进行了研究和分析,根据网络控制系统高实时性、短报文、简单实现以及低负载的特点,实现了一种简化的网络时间同步技术。试验结果表明,该技术能满足舰船动力网络控制系统的要求,并能为网络控制系统提供毫秒级的同步精度。
A real-time,deterministic and synchronized network is required for the shipboard dynamical control system.To establish a real-time and easy-to-use networked control system with short packets and low overloads,a reduced NTP-based technology is developed to perform network time synchronization.Experimental result reveals that it can meet the demands of shipboard dynamical networked control system and the synchronization granularity is millisecond.
