摘要
随着中国“数字地震观测网络”项目的启动,中国强震动观测网络将新增大量先进的数字化、网络地震动记录仪,该类型仪器具备大存储容量、自动震动触发、自动报警,本地串口通讯、远程Modem通讯、远程TCP/IP网络通讯等功能,这些先进功能为强震动数据记录、存储、强震动记录以及相关地震信息自动传输创建了硬件基础.新增的大量强震动观测设备,使得强震台网的密度进一步加大,因此可利用的强震动观测数据大大增加,但目前中国的强震观测网络无法及时的收集、分析、处理这些海量数据.而随着国家级、区域级台网中心的进一步扩建、新建,监控中心网络硬件设备、软件齐全,通讯网络大大加强,也使得大数据分析、处理、传输成为可能,在此基础上建立强震动观测无人值守信息管理自动化成为一种可能.并且随着该自动化系统的运行,积累的强震观测记录也可建立强震观测数据仓库,并在数据仓库的基础进一步建立强震分析数据挖掘方法.
With the development of Digital Earthquake Observational Network, more and more powerful digital and network strong-motion seismograph will be used in strong-motion monitoring network of China. The strong-motion seismograph was designed with huge amount of memory, automatic trigger, automatic alarm, localization serial port, remote modem communication and remote TCP/IP network communication, So it can support storeing and transporting many strong-motion records with local and remote control. And the added huge amount of strong-motion seismograph will enlarge the intensity of strong-motion monitoring network. So it can produce much more strong-motion data in short time. But now we do not have the ability of collecting, analysis and dispose the data. As the setup of national and territorial strong-motion monitoring center, the hardware, software and communication network of monitoring center will be more powerful. Then we can analyze, dispose and transport huge amount of data. This makes it possible to build self-service strong-motion observation information automatic system on the base of strong-motion monitoring network. With the automatic system development, we can build data storehouse using the accumulating strong-motion records. And by doing further work, data mining methods can be set up for analyze these strong-motion records.
