2、摘要半世紀(jì)以來(lái),隨著地震探測(cè)和電子信息技術(shù)的發(fā)展,地震檢測(cè)技術(shù)也在飛速的進(jìn)步、完善和提高。數(shù)字地震觀測(cè)及記錄手段已經(jīng)漸漸取代了傳統(tǒng)的模擬地震觀測(cè)手段。數(shù)字地震觀測(cè)的方法不僅能夠提供更大的動(dòng)態(tài)范圍、高分辨率、高穩(wěn)定性的地震測(cè)量數(shù)據(jù),而且還易于操作、與計(jì)算機(jī)連接,使得數(shù)據(jù)的維護(hù)更加便捷,因此在地震數(shù)據(jù)采集測(cè)量方面日益重要。本文主要對(duì)數(shù)字地震數(shù)據(jù)采集監(jiān)控中心子系統(tǒng)的設(shè)計(jì)方案、關(guān)鍵技術(shù)、系統(tǒng)功能等方面進(jìn)行了研究和分析。本文論述了監(jiān)控中心子系統(tǒng)的設(shè)計(jì)方案,也就是PC監(jiān)控機(jī)軟件的結(jié)構(gòu)和組成,對(duì)軟件的各個(gè)組成部分功能作了概述,并根據(jù)實(shí)際要求給出了系統(tǒng)的設(shè)計(jì)目標(biāo)及方案。詳細(xì)闡述了軟件的開(kāi)發(fā)過(guò)程,內(nèi)容包括開(kāi)發(fā)
3、方式敏捷方法的應(yīng)用,及.NET開(kāi)發(fā)平臺(tái)的環(huán)境和軟件的開(kāi)發(fā)技術(shù)要點(diǎn)等。著重論述了串行通信的方式、多線程編程的要點(diǎn)、組件化編程的設(shè)計(jì)思路等。利用WindowsAPI編寫串口通信類,對(duì)采集終端進(jìn)行控制,包括向終端發(fā)送不同的命令,處理終端發(fā)送來(lái)的數(shù)據(jù),對(duì)地震測(cè)量數(shù)據(jù)進(jìn)行存儲(chǔ),并以圖形方式顯示,最終設(shè)計(jì)完成一個(gè)數(shù)據(jù)采集控制子系統(tǒng)的集成環(huán)境。實(shí)驗(yàn)結(jié)果表明,數(shù)據(jù)采集傳輸控制系統(tǒng)較好的實(shí)現(xiàn)各項(xiàng)主要功能,可以應(yīng)用于實(shí)際測(cè)量。關(guān)鍵詞:數(shù)據(jù)采集;組件技術(shù);串行通信;多線程編程ABSTRACTSincethehalfacentury,withthedevelopmentofearthquakeobservation
