AETA多分量地震监测系统的数据存储与安全系统

Data Storage and Security System for AETA Multi-component Seismic Monitoring System

AETA多分量地震监测系统由地声传感探头、电磁传感探头、数据处理终端和云端应用服务器、数据存储中心、数据分析系统组成。海量传感数据的云端存储与安全,是保障系统长期稳定运行的一大关键问题。文中介绍了AETA多分量地震监测系统中数据存储与安全系统的设计和实现。数据存储方面,将原始数据和特征数据分别存储在磁盘文件系统和关系型数据库MySQL中,其中原始数据采用RAID进行本地备份,特征数据基于MySQL复制、XtraBackup和二进制日志等机制进行数据备份。数据安全访问方面,设计并实现了一套数据访问中间件来代理所有数据访问请求,避免了客户端与数据源的异地直接连接,同时也向用户屏蔽了数据源的相关结构和操作,提升了数据访问的安全性。

The AETA multi-component seismic monitoring system consists of acoustic sensing probes,electro-magnetic sensing probes,data processing terminals and application servers,data storage centers,data analysis systems in the cloud.Cloud storage and security of mass data is a key issue to ensure long-term stable operation of AETA system.Therefore,we explore the design and implementation of data security storage scheme for AETA multi-component seismic monitoring system.In terms of data storage,the original data and eigenvalue data are stored in the disk file system and relational database separately.RAIDs is used for the local backup of original data,and MySQL replication,XtraBackup and binary log mechanism are used for eigenvalue data backup.In terms of data security access,a set of data access middleware is implemented to proxy all data access requests,which avoids the direct connection between clients and data source,and improves data access security by shielding the structure and operation of data source from normal users.
