[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.
