借鉴美国地质调查局(USGS)开发的Earthworm地震监测系统中自动地震定位模块的思想,将其中binder_ew软件模块功能应用到中国地震台网中心(CENC)开发的国家数字地震台网地震实时监测系统软件Ecums_rt中,运用地震震相关联方法,降低误触发地震台站对地震自动定位的干扰,从而实现软件优化,提升了Ecums_rt系统的地震事件自动定位监测能力。
This paper refers to the idea of the automatic location module in the Earthworm system developed by the USGS and applies the binder_ew module to the Real-Time Monitoring System of the National Digital Seismic Network (Ecums_rt). After using the seismic phase association method, the Ecums_rt system is improved by reducing the interference from the miss-triggered stations and enhancing the automatic location and monitoring capability of the system.
