| 中文摘要 | This paper mainly introduces the monitor system for the miniature hydrogen atomic clock, which is being developed by Shanghai Astronomical Observatory at present. This system realizes the functions as follows: monitoring and controlling working conditions of the clock, automatic start-up and shut-down, automatic parameter detection, controlling and modifying the frequency of synthesizer, the temperature of the microwave cavity and the hydrogen beam flux. The design of the cavity temperature control system is also introduced in this paper, which is mainly about using the software to control the digital resistors to set the temperature in the cavity temperature system. This paper first introduces the general development of the hydrogen atomic clock as well as the significance and task for it, then states the general architecture of the hydrogen atomic clock intelligent control system, performance target, monitoring target, main function and appearance design. The paper also describes the concrete design methods of hardware and software in the following three chapters. After repeated test and validation, the result and analysis are given out in the sixth chapter, which shows that we have basically achieved the purpose we expected before. For maintenance and convenience in the future, the seventh chapter describes the interface definition and direction for use. At the end of this paper, it simply discusses the further improvement of this system. |
| 英文摘要 | 本文主要介绍了目前上海天文台正在研制的小型氢原子钟的监控系统。氢原子钟的监控系统，它可以监控氢钟的工作情况，实现氢钟的自动开、关机，参数自动检测，可控制综合器的频率变化（即对应氢钟输出频率最小可调分辨率 ），微波腔温度，氢离子流的大小。文中还介绍了恒温系统的设计与制作，主要为利用软件控制数字电阻器实现恒温系统温度的自动设置。 文章首先介绍了氢原子钟的发展概况以及研究的意义和任务。接着讲述了氢原子钟智能化控制系统的总体设计方案，提出了系统所要达到的性能指标，确定了系统的监控对象、主要实现功能和外观设计。然后在第三、四章介绍了系统的硬件设计；第五章详细介绍了系统的软件设计。第六章在对电路反复的测试和长时间的检验后，给出了系统的测试结果和分析，测试结果表明设计达到了预期的目的。为了系统的维护和使用方便，第七章讲述了系统接口定义及使用说明。最后给出了本人对氢原子钟智能化监控系统进一步改进的设想。 |
