网络技术在时间服务工作中的应用

主要介绍网络技术在授时中心守时实验室的守时及授时服务系统中的应用情况。守时系统是一种需要连续、可靠运转的复杂系统，包括守时钟组、比对测量系统、原子时归算等多个环节。原子时专用局域网是守时系统的一个重要的组成部分，它有效地提高了守时、原子时及相关数据资料的传递和交换速率。时间服务的网络化、自动化不仅有效提高了工作效率，减少了人工过多干预造成的误差，更重要的是可以提高守时系统的可靠性和合理性。章详细介绍原子时局域网络（ATLAN）系统和计算机网络授时系统的设计情况。

Application of Network Techniques to Time Keeping and Time Service System

The application of the computer network to the time keeping and time service system established at the National Time Service Center (CSAO originally)is introduced.A time keeping system consists of atomic clock assembly,measuring and comparing system and computation of atomic time scale, etc.,and it needs to run continuously and reliably.As an important part of the time keeping system at NTSC,the atomic time local area network(ATLAN) has greatly improved the exchange rate of data and information for the time keeping and atomic time system.Networking and automating of the standard time service can improve the efficiency,reduce the mistake caused by accident manual operation,most importantly,it can also improve the reliability and reasonableness of the time keeping system.A practical atomic time local area network(ATLAN)and a computer network time transmission system are presented in detail.
