分布数据源两级分类转换处理的技术研究

Study on the Technology of Two-level Classification Conversion Processing of Distributed Data Source

研制了一种变电站继电保护装置信息采集数据插入性能优化的技术,从部件结构、集成转换控制等层面,改进了分布数据源并发访问导致的应用程序与数据库交互占用大量系统资源,严重影响系统性能的问题。试验证明,该技术解决了分布数据源并发访问入库性能慢、网络问题导致数据易丢失等问题。经过模拟100万条数据并发访问测试,各服务器CPU及磁盘IO占用率低,没有丢失数据发生,系统运行非常稳定。

A technology was developed to optimize information acquisition and data insertion of the relay protection device of the transformer substation. Considering that the concurrent access of distributed data sources might result in a huge amount of system resources occupied by applications and data interaction, thus seriously influencing the system performance, the author attempted to use the technology to ad- dress the problem from the perspective of unit construction and integrated conversion control. Experimen- tal results show that the technology successfully resolves problems of slow storage caused by concurrent access of distributed sources and data loss caused by network. The simulating test of concurrent access of 1 million pieces show that there has been a low utilization rate of the servers CPU and the disks IO, and the system has operated steadily with no data loss.
