With the number of the digital seismic stations increasing, the means of data transmission are more and more diversifying. Meanwhile, as the earthquake early warning system being developed, it is very important to the data transmission that using effective and real-time algorithm to compress earthquake data. We propose a compression algorithm which support the low delay time (the transmission interval <1 second) data transmission requirement at this page. By theory analysis and test with practical earthquake data, it is an effective, easy in implementation and can be used at the earthquake early warning system.%随着数字地震台站数量的增加、数据传输手段的多样化以及地震预警系统的发展,对地震数据实现有效的实时压缩对数据传输显得十分重要.本文提出一种支持低时间延迟(数据传输间隔小于1 s)数据传输要求的实时数据压缩算法.通过理论估算和实际地震数据检验,该方法高效、易实现,适用于地震预警等领域.
