实现信息系统的自主、安全、可控已成为测控中心系统的研究方向和建设目标。研究应用自主可控数据库是实现测控中心系统全面自主可控的重要环节。目前,卫星控制中心的数据存储系统大多以Oracle数据库为主,软件和技术服务费用昂贵,更新维护成本高,且可能带有信息安全和任务安全方面的风险。针对上述这些问题,研究分析了开源数据库MySQL在卫星控制中心系统中应用的可行性,对MySQL数据库做了全面测试,包括功能、性能、系统级的高可用测试,以及MySQL与Oracle数据库的性能对比测试。研究和测试结果表明,MySQL开源数据库可以用于卫星控制中心系统以及类似的测控中心应用系统,对今后测控中心系统应用自主可控数据库具有参考价值和借鉴意义。
Realization of autonomous, safe and controllable information system has become the research direction and target of the monitoring and control center system. Research and application of independent controllable database is an important part of the complete control of the control center system. At present, most of the data storage systems in satellite control centers are Oracle databases. Software and technical services are expensive, update and maintenance costs are high, and risks of information security and mission security may be brought. In view of the above problems, this paper analyzes and analyzes the feasibility of using MySQL as an open source database in the satellite control center system. It tests the MySQL database comprehensively, including function, performance, high availability test at the system level, and comparison between MySQL and Oracle database test. Research and test results show that MySQL open source database can be used in satellite control center system and similar monitoring and control center application system, which has reference value and reference significance for the application of autonomous controllable database in the future monitoring and control center system.
