中国科学院国家授时中心负责我国标准时间UTC(NTSC)产生、保持和发播.但是,国家授时中心的UTC(NTSC)保持硬件设备都处在实际应用运行中,不具备作为实验平台的条件,阻碍了对UTC(NTSC)保持工作的研究.为了解决这个问题,通过分析时间保持系统的硬件构成和软件部分,建立了自动监控实验平台.该实验平台具备时间保持的功能,可用于国家授时中心时间保持方面的研究工作.“,”Timekeeping is one of the main missions at each time laboratory.The time scale UTC(NTSC),which is used the standard time in various fields reference directly or indirectly in China,is generated,kept and transmitted by the National Time Service Center(NTSC),the Chinese Academy of Sciences.However,equipments for UTC(NTSC) timekeeping are in operation,and do not have the conditions as the experiment platform at NTSC.They block timekeeping researches of UTC(NTSC).In order to solve this problem,an automatic monitor experiment system has been built by analyzing hardware and software of timekeeping system.This platform,which possesses the timekeeping function,can be used for researches on timekeeping aspects.
