| 摘 要： | 本文介绍了一种基于Java语言的测震miniSEED格式数据的解压缩方法和数据实时展示程序。程序能够通过Java的socket接口接入测震流服务器,自动接收liss数据流并解压缩测震miniSEED格式数据。使用队列与缓冲池技术将解压缩的数据分流、过滤,并以ASCII码的数据形式进行存储,最终通过web对数据进行实时发布,以提供测震波形数据实时在线服务。

| Abstract: | This paper introduces a method of data compression based on Java language, and a program which could shows the data on Web. The program can access the socket java interface to measure the earthquake flow server, automatically receiving LISS data stream and extract the data from the miniSEED format. The data is separated and filtered by using a queue and buffer pool to extract the station and channel field in the miniSEED header block in the form of ASCII code form.It makes astep forward in the real-time earthquake waveform. That could be a foundation of analyzing and service of the seismic data. |
