中文摘要: 随着气象事业的发展和制作精细化预报的需求,气象业务系统对时间的要求及时间概念的重要性愈来愈被认识。统一气象业务系统的时间,对提高观测数据质量起到十分重要的作用。GPS Net授时系统是采用GPS时间源及系统接收软件技术,对计算机进行授时服务。通过Network网络授时发布软件和Network用户终端接收软件技术,将标准的时间经过网络传递给若干用户,同时还要充分考虑GPS系统安全和网络安全。结果表明:GPS Net授时系统能准确地获取GPS时间源信息,并通过网络技术发布到用户终端上,使气象业务系统获得标准的时间误差小于1秒。由于采用网络发布式和气象内网限制方式,有效地减少了服务器和用户终端的负担,防止了外网病毒与黑客的侵入。GPS Net授时系统为气象装备和气象业务系统,提供了快捷、准确、自动的授时解决方案。
Abstract:With the development of the meteorological cause and the requirement of fine weather forecast, the requirement and concept of time are been recognized more and more important for meteorological operational system. The unified time of meteorological operational system plays an important role in improving the quality of observation data. GPS NET time service system uses the GPS time source and system received software technology to make time service for computer. Standard time can be transmitted to certain users by net with Network time service publishing and Network user terminal received software. At the same time, the security of the GPS system and Network is considered fully. The results show that: GPS NET time service system can obtain GPS time source information accurately and release to user terminals through network technology to make meteorological oper〖HJ〗ational system obtain the standard time (error <1 s). The way of network publishing and meteorological internal network limitation can reduce the server and user terminal’s burden effectively and preventing external net virus’s invasion. The quick, exact and synchronization solution of time service is provided for meteorological equipment and meteorological operation by GPS Net time service system.
