NTSC时频基准实验室守时系统自动监测软件

为了能实时了解中国科学院国家授时中心（NTSC）时频基准实验室守时系统的运转情况，编制了本软件。本软件的功能是对系统中原子钟最近一个月的比对数据进行实时计算后，得到一个纸面的加权平均时间尺度“TA”，用它作为监测UTC（NTSC）、UTC（JATC）和原子钟运转情况的参考，给出TA-UTC（NTSC）、TA-UTC（JATC）、以及每个钟相对于TA的速率曲线。通过选用窗体上设置的各个按钮，能很方便地监测原子钟和测量设备的运行情况。位于陕西蒲城的BPL监控室可以通过远程局域网得到NTSC守时实验室的数据，实时运行本软件，并用TA作为参考，即可监测BPL监控室原子钟运行情况，并且对BPL发播工作钟时间T（PU）进行监测和频率驾驭，以实现T（Pu）同步到扩形（NTSC）。

Software for Real Time Monitoring the Time Keeping System at NTSC Standard Time and Frequency Laboratory

A software has been established for real time easily monitoring the operation of the time keeping system at the National Time service center （NTSC）, the Chinese Academy of Sciences. The time comparison data for the latest nearly one month are used in the data processing and a paper time scale ＂TA＂ on the bases of the weighted average of the clock data is obtained. The TA is used as a reference to monitor UTC（NTSC）, UTC（JATC） and the running of the clocks. The curves of TA-UTC （NTSC）, TA-UTC （JATC） and the rates of TA-clock （i） are displayed in the windows designed. People can easily press the command buttons in the windows to observe the running situation of the equipment. The BPL monitoring and controlling station at Pucheng, Shaanxi can obtain the time comparison data generated at NTSC through a local network. With this software running at BPL station at real time and taking TA as a reference, the rates of the atomic clocks at BPL station can be checked, the time signal of BPL working clock, T（PU）, can be monitored and the frequency of T（PU） can be steered in order for T（PU） to synchronize to UTC（NTSC）.
