随着计算机网络的迅猛发展,网络应用已经非常普遍,众多领域的网络系统如电力、石化、金融业(证券、银行)、广电业(广播、电视)、交通业(火车、飞机)等需要在大范围保持计算机的时间同步和时间准确。因此一个好的时间发生器是非常必要的。为了适应这些领域对于时间越来越精密的要求,济南唯尚电子有限公司自行研制开发了NTP同步时钟,产品在继承卫星同步钟所有功能的同时,内嵌国际流行的NTP-SERVER服务,以NTP/SNTP协议给各个网络设备提供精确的时间校对服务,独立于其他网络系统,可直接作为网络校时服务器接入网络。具有多种校时方式,使用方便。
网络时间同步系统的特点
1、大屏幕显示,汉化菜单操作,人机界面良好,轻触按键控制,使用灵活方便;
2、一或两路网络(RJ45)授时,提供可设置的IP地址,作为独立的网络时间服务器,以国际流行的NTP-SERVER协议提供高精度的网络对时服务,并提供客户端对时软件,适用于WINDOWSUNIX等不同操作系统、不同网段之间的时间统一校对要求;
3、采用美国MOTOLORA公司的专业GPS授时芯片,时间精度高,信号捕获能力强。经过国际认可的 USNO实验室的广泛测试认可的6 Sigma 授时水平的出色表现。如要求,可提供全套的测试报告;
4、采用摩托罗拉32位高性能单片机和商用实时多任务操作系统,使产品的稳定性和运算速度得到可靠保证;
5、高品质的工业级元件,高水准的电气设计,高密度集成的电路结构,使装置拥有优异的电气隔离和电磁屏蔽表现,整机无可调节器件,极大提高了装置的抗干扰性能与可靠性保障;
6、宽电压范围交直流输入,以满足用户不同的电源选择要求;
7、有多路可编程设定秒、分、时钟同步脉冲输出,并可经串行口输出
8、可同时为几十万台客户端、服务器、工作站提供时间校时服务。
9、支持WINDOWS9X/NT/2000/XP/2003/2008/vistaLINUXUNIXSUN SOLARISIBM AIXHP-UX等操作系统及支持NTP协议的路由器、交换机、智能控制器等网络设备。
10、装置采用全模块化即插即用结构设计,支持板卡热插拔,配置灵活,维护方便,同时为将来现场网络改造扩建时增加对时端口提供了方便。
网络时间同步系统的技术指标:
