【摘要】：国家授时中心(National Time Service Center—NTSC)的时间基准系统承担我国高精度时间的产生和保持的重要任务,由主(原子钟、时间传递)、辅(温湿度、电压环境监控系统)、外(电源系统)三个子系统组成。时间基准系统必须24小时无故障、不间断的工作,但由于各种外界的、内在的因素,故障在所难免,出现故障后快速诊断、快速定位就成为守时工作人员始终关注的问题。同时,由于时间工作的特殊性,守时系统最重要的特征是要求连续、稳定。时间基准系统中的守时钟和主要测量比对设备等同类型设备一般具有相似的性能和故障表现,因此,以“电子病历”数据库的形式,基于时间基准系统的局域网络环境采集主要设备的运行参数,通过对系统中主要设备的运行状态、故障表现、维护维修记录等建立电子档案,实时监测时间基准系统的运行状态,就可以在故障发生时能迅速锁定故障设备和位置,从而尽快恢复系统的正常工作,保障整个系统的安全可靠运行。本文通过对主、辅、外三个子系统进行故障监测、故障检测、故障报警、故障处理以及“电子病历”数据库的建立,探索实现时间基准系统无故障连续运转、无人值守的运行模式。论文的主要研究内容有: 1、阐述了时间基准系统“电子病历”数据库的理论基础,包括守时理论与技术相关理论知识,原子钟的数据特征、Vondrak数据平滑算法、最小二乘法数据平滑算法、故障检测算法等。 2、基于时间基准系统监测的实时性、自动性特点,给出了“电子病历”数据库软件设计的总需求:基于时频基准系统专用原子时局域网络,进行数据、资料和信息的收集和处理;根据原子钟的内部工作参数,判断原子钟的工作情况和可能的故障隐患,并及早给出告警;通过对测量比对数据的分析处理,对主要测量比对设备的运行情况给出报告;基于软件工具给出图表报告;建立时间基准系统病历数据库。 3、使用C# + SQL sever2005,Dundas Chart控件等实现了守时监测系统的开发,整个系统包括五个子系统:原子钟子系统、故障检测子系统、电子病历数据库子系统、故障处理子系统、系统维护子系统,详细介绍了各个子系统之间的接口和所编写软件的各项功能。 4、利用模拟方法对“电子病历”数据库进行了测试,结果表明数据库故障检测准确、故障处理及时、信息记录完整,符合研究预期目标。
[Abstract]:The time reference system of National Time Service Center (NTC) is responsible for the production and maintenance of high precision time in China. It is composed of three subsystems: main (atomic clock, time transfer system), auxiliary (temperature and humidity, voltage and environment monitoring system, external (power supply system)). The time reference system must work 24 hours without failure and without interruption. However, due to various external, internal factors, the fault is inevitable, the rapid diagnosis after the fault, rapid positioning has become a problem that the punctual staff always pay attention to. At the same time, because of the particularity of the time work. The most important feature of time-keeping system is that it requires continuity and stability. The clock and main measuring equipment in time reference system generally have similar performance and fault performance. In the form of "electronic medical record" database, the local network environment based on the time reference system collects the operation parameters of the main equipment, through the running state of the main equipment in the system, the fault performance. Maintenance of maintenance records such as the establishment of electronic files, real-time monitoring of the running status of the time reference system, can quickly lock down the fault equipment and location when the fault, thus as soon as possible to restore the normal operation of the system. To ensure the safe and reliable operation of the whole system. This paper through the main, auxiliary, external three subsystems of fault monitoring, fault detection, fault alarm, fault processing and "electronic medical record" database establishment. To explore the implementation of the time benchmark system without fault continuous operation, unattended operation mode. The main contents of this thesis are as follows: 1. The theoretical basis of the electronic medical record database of time reference system is expounded, including the theory of punctuality and technology, the data characteristics of atomic clock and the Vondrak data smoothing algorithm. Least square data smoothing algorithm, fault detection algorithm and so on. 2. Based on the real-time and automatic characteristics of time reference system monitoring, the total requirement of the design of electronic medical record database software is given: based on the special atomic time local area network of time-frequency reference system, the data is carried out. Collection and processing of information and information; According to the internal working parameters of atomic clock, the working condition and possible trouble of atomic clock are judged, and the alarm is given as soon as possible. Through the analysis and processing of the measurement and comparison data, the paper gives a report on the operation of the main measuring and comparing equipment. Give chart report based on software tool; Establish the time benchmark system medical record database. 3. Using C # SQL sever 2005 Dundas Chart control to realize the development of punctuality monitoring system. The whole system includes five subsystems: atomic clock subsystem, fault detection subsystem, electronic medical record database subsystem, fault processing subsystem, system maintenance subsystem. The interface between each subsystem and the functions of the software are introduced in detail. 4. The electronic medical record database is tested by simulation method. The results show that the database fault detection is accurate, the fault processing is timely, and the information record is complete, which is in line with the expected goal of the research.
