快速获取地震预警信息在地震预警系统中十分重要。目前的地震预警技术多是基于区域地震台网,均需依托测震或强震动观测台网,其时效性受到观测台站与台网中心间数据传输速度的制约。本文设计了地震预警信息的在线获取系统,可通过前端专用MEMS传感器获取地震动数据,由本地CPU进行实时处理,实现地震预警信息的在线获取,并通过3G无线通信网络进行信息公布,可满足地震预警的时效性与准确性的要求。
It is very important to get earthquake early warning information quickly in the earthquake early warning system. The current earthquake early warning technology is mostly based on the regional seismic network, both need to rely on the strong earthquake or seismic observation station network, the timeliness of the observation station and network center by the data transmission speed constraints. In this paper, an online acquisition system of seismic early warning information is designed. The seismic data can be acquired by the front-end dedicated MEMS sensor and processed by the local CPU in real time to obtain the earthquake pre-warning information online. The information is released through the 3G wireless communication network to meet the earthquake Timeliness and accuracy of early warning requirements.
