近年來自動化監測系統已逐漸受到工程界的重視,本研究目的旨在以時域反射法(Time Domain Reflectometry, TDR)為中心主軸發展自動化監測系統。TDR具備有一機多頻道、多功能的優點,適用於遠端自動化,但現有TDR資料擷取器運算能力不足,必須將擷取後的TDR波形訊號經由遠端傳輸回伺服器上進行運算分析,無法於現地即時換算為物理量。因此本研究採用新式的資料擷取器以改善TDR自動化監測系統的硬體運算能力,並考量使用者於軟體操作便利性,設計包含TDR多功能量測的圖形化介面軟體。基於監測硬體系統改良與人性化操控軟體介面建置,提供完善之自動化監測系統。
監測系統改良首要考量硬體的運算能力,其次考慮環境條件對硬體系統的影響和足夠的連接介面,因此本研究採用嵌入式系統以整合TDR監測與傳統感測技術。軟體方面則配合TDR多功能與多頻道的特色,開發人機互動操作程式與自動化監測程式。人機互動操作程式可提供現地人員即時操作與查詢之用,而自動化監測程式因功能需求而區分伺服器端介面與遠端介面。伺服器端介面可擷取遠端監測結果並控制遠端系統,遠端介面則提供定時資料擷取與分析之設定與執行。成果顯示配合硬體改善與人性化操控軟體介面建置,可提升TDR監測即時分析效率與系統操作便利性。但本系統於現地測試常有穩定性不足的情況,建議須進一步評估系統穩定性,以俾實際工程應用。
Recently automatic monitoring systems are gradually concerned in construction business. The purpose of this study is to develop an automatic monitoring system including Time Domain Reflectometry (TDR) sensing technique. The monitoring system with TDR technique has advantages of multi-channel, multi-functional and automation. However, the computing capability of the existing TDR data logger is not sufficient for TDR waveform processing, meaning that physical parameters cannot be acquired immediately from TDR data logger. The raw data must be transmitted to server for further computing and analysis. Therefore, this study provides a new hardware by replacing existing TDR data logger to improve computation capability firstly, and designs relative software with user-friendly interface for operating efficiency.
The prior consideration of hardware selectivity is sufficient computation ability, and integration for both TDR and conventional monitoring devices minor. Consequently, this study uses embedded system to meet the aforementioned requirements. Then TDR software is developed based on TDR characteristics of multi-channel and multi-functional, and this software includes both human-computer interaction program and automatic monitoring program. The interaction program provides TDR acquisition setting and intermediate data quarry. Furthermore, the automatic monitoring program is divided into the server-side interface and the remote-side interface by demand. The function of the server-side interface is to control the remote systems and acquire the monitoring data from remote system. The remote-side interface provides functions of data acquisition and processing periodically. Finally, the results show that the combination of hardware improvement and user-friendly software increases ability of automation system and operation efficiency. However, the new TDR monitoring system needs further in-situ verification of stability.
