摘要
通过对大型船舶子母钟系统进行研究分析,获得船钟信号特征;基于船钟时间信号的高精度特点,提出一种采用船钟信号作为基准来同步计算机网络时间的方法;设计开发出隔离型串口转换电路、网络时间同步服务器和客户端软件,实现计算机网络时间与船钟时间的同步调整;解决了在无互联网时间同步服务器的情况下,船舶穿越不同时区时的时间自动校准和同步调整问题。
The feature of ship-borne clock is obtained by the analysis of network time synchronization system. Based on precise ship-borne clock, the system including low-cost serial peripheral, network time synchronization server and client are put.forward. The computers can check time by system, which are on offshore ship without world-wide network time synchronization server. Not only the precision of computer time is improved greatly, but also the time automatic check can be realized across the time zone.
