| 近年來由於科技之進步，非破壞檢測技術對公共工程構造物在施工期間之品質管制與長期使用之安全評估具有無可取代之重要性。在歐美等先進國家經歷多年之努力，土木工程非破壞檢測技術之發展已有相當成果。其中之音波回音法(Sonic Echo)更是常用來檢測基椿之完整性的一種技術。 本研究以現有的Impact Hammer為敲擊源、Accelerometer為接收器，利用LabVIEW(Laboratory Virtual Instrument Engineering Workbench)為開發環境，使用類比數位轉換卡進行波型訊號之擷取及轉換成數位數據，研發出一套以音波回音檢測技術為基礎的非破壞檢測軟體，該軟體具備訊號擷取及立即分析運算的能力，建構出圖形化輸入介面之形式，讓使用者在人性化的面版上，可進行：資料擷取、分析與展現。 綜合本研究之經驗得到以下的結論：以LabVIEW來撰寫程式，與傳統程式語言相較下，滅少開發時間及金錢，並且確實把硬體設備縮小。對於訊號擷取與分析運算，可在相同的視窗介面下同時進行，不但增加使用者與系統的互動且介面簡單化，建立出人性化的檢測系統。 |

| In recent years, the advancement of Non-destructive Testing (NDT) technology is incomparably important for the infrastructure structure in its quality control during construction period and in its safety evaluation for long-term use. With many year’s efforts, development of the NDT techniques reaches considerable achievement in Europe and in America. Among them, the Sonic Echo method is a technology that is often used to evaluate the integrity of piles. The objective of this thesis is to develope a Sonic Echo NDT system which uses existing impact hammer as the impact source, accelerometer as the receiver, and uses an analog-to-digital (A/D) converter to convert the analog signal into digital form. The software utilizes a graphic user interface thus making data retrieval, data analysis and data presentation in a single step . Based on the experience learned form this research, it can be concluded that: in comparison to the traditional programming language, using the LabVIEW platform can save development time and money. In addition the resulting interface is much more user friendly. |
