GPS卫星同步授时与网络校时系统的研制及应用

Developing and applying of System for GPS satelite giving time synchronously and correcting time in network

系统通过在局域网内设置的时间服务器,接收GPS全球定位系统的标准时间,并通过局域网,以TCP/IP协议将标准时间发送到各个联入网络的工作站,同步校对各工作站,从而为工作站上应用的各种铁路运输管理软件,提供一个精确标准的时间基准,解决各工作站时间不准确、不同步的问题。而且该系统的时间和分局调度所的时间是完全同步的;同时该系统还能驱动LED大屏和LCD液晶显示器对外进行时间显示,方便工作人员查看时间。

The System received the standand time of GPS form time server installed in LAN, and sent it to connect network station according to TCP/IP, corrected synchronously time of network station, resolved the problem of uncorreting time by offering standand time for various railway transportation managing software of network station.
