三维闪电探测数据处理存储系统设计与实现

Design and Implementation of Three-Dimensional Lightning Detection Data Processing and Storage System

针对三维闪电探测系统接收处理的数据量相比二维闪电探测系统增加数倍,定位、回击与状态数据入库流程相较二维系统复杂许多的问题,使用Oracle数据库和PL(Procedural Language)/SQL(Structured Quevy Language) developer集成环境开发了三维闪电探测数据处理存储系统。通过设计三维闪电定位仪站点信息表存储站点基本信息;设计闪电定位结果信息表存储处理后的定位数据和回击数据;设计最新状态信息表存储定位仪的最近一条状态信息,用其可判断设备状态是否正常。通过湖北省三维闪电探测网构建实验平台验证系统功能和运行状况,结果表明,处理存储系统设计与实现满足三维闪电探测系统数据处理与存储功能的任务需求。

In view of the problem that the amount of data received and processed by the three-dimensional lightning detection system is several times higher than that of the two-dimensional lightning detection system, and the warehousing process of positioning, return stroke and status data is much more complex than that of the two-dimensional system, a three-dimensional lightning detection data processing and storage system is developed using Oracle database and PL(Procedural Language)/SQL(Structured Quevy Language) developer integrated environment. The basic information of the station is stored by designing the location information table of the three-dimensional lightning locator. The lightning location result information table is designed to store the processed positioning data and return stroke data. The latest state information table is designed to store the latest status information of the locator. And this information can be used to determine whether the device is in normal state. Through the construction of an experimental platform of Hubei three-dimensional lightning detection network, the function and operation state of the system are verified. The results show that the design and implementation of the processing storage system meet the mission requirements of the data processing and storage function of the three-dimensional lightning detection system.
