基于Oracle的SSRF数据存档系统及接口设计

Oracle-based data archiver system and interface design for SSRF

上海光源(SSRF)采用EPICS作分布式控制系统的软件平台。Channel Archiver是EPICS自带的OPI层数据存档工具集,实现对EPICS控制系统运行过程中各种数据的快速存取及检索。本文对EPICS数据存档系统进行分析,提出现有的不足,并针对这些不足,结合Oracle数据库对存档系统重新设计,实现中央数据库统一存储和管理加速器运行数据,并采用Web Services技术提供访问数据库的统一接口。

SSRF,as a national scientific base in China to provide synchrotron radiations from IR to hard X-rays for hundreds of scientists working simultaneously on the experimental stations,needs an efficient software platform for the facility control and user service.It uses a distributed control system of EPICS,which is commonly used home and abroad in large scientific facilities.Channel Archiver is an archiving toolset for EPICS,which is used to store and retrieve different types of data generated by EPICS.Based on analysis of Archive System,we have found some ways to overcome the defects in existing,and designed a new archiver system using Oracle database.This offers a unified interface for varieties of programs.
