摘要
阐述了守时系统的硬件模块与软件模块,介绍两台主动型氢钟和八台铯钟组成的守时钟组,论述钟组运行模式。探究ALGOS原子时算法,采用百分比限权法对原子钟的权重加以设定,保障算法的可靠性。通过稳定的钟组及可靠的原子时算法使守时系统正常运行,从而服务时间频率计量体系建设。
This paper discusses the operation mode of the time-keeping system through explanation of its hardware modules and software modules of and the introduction of the clock set which consists of two active hydrogen clocks and eight cesium clock.Studying ALGOS atom time algorithm,we use the method of percentage limiting to set the weight of the atomic clock.By this way,we could ensure the algorithm is reliable.The normal operation of the time-keeping system depends on the steady clock set and the reliable atomic time algorithm,which serves to establish the time frequency metrology system.
