摘要
中国数字地震台网(即CDSN)自1986年10月起,记录了大量的超长周期(VLP)地震数据,这些VLP地震数据以同月带记录形式存放。网月带中,数据格式有ASCⅡ码、BCD码和二进制数据3种形式。本文提出了CDSN同月带VLP地震数据的解调方法,分析了网月带的数据结构,输出VLP地震数据文件。同时,编制了配套的《CDSN超长周期地震记录处理软件》。《软件》使用TurboC和QuickBASIC两种语言编制,其中数据解调和图形回放等功能模块由TurboC语言完成,管理程序由QuickBASIC语言实现。
China Digital Seismograph Network, that is CDSN, has recorded lots of very long period (VLP) seismogram data since October of 1986. All of those data are kept in form of Network-month tape, in which there are three types of data format, ASC Ⅱ code, BCD code and binary data. VLP seismogram records are deciphered from Network-month tape of China Digital Seismograph Network. This paper analysed data blocks of Network-month tape and produce VLP seismogram data file. Meanwhile, it offers a software entitled "CDSN VERY LONG PERIOD SEISMOGRAM DATA PROCESSING SOFTWARE". This software is completed in two kinds of languages, while the programme on data decipherment and seismogram show are writtern in Turbo C language, and manu management are done in Quick BASIC language.
