早期的監測系統,需要研究人員親赴監測現場將監測資料取回。隨著通訊設備、儀器的快速發展,數據機開始在資料擷取單元和個人電腦間的資料傳輸上扮演著重要的角色,加上運用寬頻網路,如:ISDN、ADSL、Cable Modem等,提高了監測系統能即時調整的可能性,故隨著監測技術的進步能更快且可靠的取得資料,更有效的監測系統也應該開始發展。本研究對寬頻網路監測系統加以詳細介紹,並針對結構物地震反應特性與配合利用寬頻網路傳輸資料之要求,撰寫相關監控與分析程式,其功能包括(一)線上監測系統調整,(二)即時資料分析,(三)即時警示系統,(四)定時監測與(五)資料後處理與分析。研究過程中利用寬頻網路及四十天的長時間監測資料收集,測試此一監控與分析程式之實用性,且探討取樣率對即時效能之影響。研究結果顯示,此一監控與分析程式能有效的進行監測資料之收集,並將收集到的監測資料加以處理及進行相關分析,可供工程界應用。
In early stage, the investigators have to go to the location of data acquisition unit and fetch the data in person. Owning to dramatic innovation in communication technique, modems play an important role to communicate bilaterally between personal computer and data acquisition unit. Furthermore, the broadband network access, ISDN, ADSL, Cable Model etc., offers the possibility of real-time and on-line monitoring and adjustment. By the faster and more reliable data collecting technique, a prototype on-line monitoring system would be established. In this paper, monitoring system with broadband network will be introduced in detail, the monitoring and analysis program about earthquake response characteristics of the structure would be developed and meet the request of use monitoring system with broadband network to transmit the data. The program functions include:(1) on-line adjustment of monitoring system,(2) real time data analysis,(3) real time warning system,(4) timer setting of monitoring system,(5) data processing and analyzing. In the process of research, broadband network to transmit data and remote monitoring are applied in forty-day test to verify the practicality of the program and investigate the influence of sampling rate on real time performance of monitoring system. It is found that the whole system does show its potential to be installed in a real structure as a health monitoring system. Therefore, the broad-band network monitoring system processes the possibility in practical applications.
