摘要

本論文提出一無線化橋樑結構監測系統，主要係將前端感測器(sensors)無線化，再引入無線感測器網路技術(Wireless Sensor Network, WSN)進行整合設計。透過具多點跳躍傳輸(multi-hop relay)能力之無線感測器網路的輔助，於實際環境佈署結構監測點(即前端感測器)之困難度與不便性可大幅降低，且各個監測點所擷取到的原始資料(raw data)均以無線接力傳輸方式傳送至後端監測中心，並自動地記錄所擷取到的數據資料，以便工程監控人員進行資料分析以及後續維護與處理，提升橋樑結構之監控效率，以進一步邁向智慧型公共建設之目標。
　　為了讓佈署於橋樑結構監測點之前端感測器能與無線感測器網路進行銜接，本系統主要針對測量橋樑傾斜度與環境溫度等參數之感測器，設計一介面電路(interface circuit)並與感測器整合以進行訊號擷取，並轉換成數據封包再透過無線通訊模組將訊號傳至無線感測器網路以進行資料接力傳輸。
　　最後，本論文實際研製一雛型系統，透過實測結果與最後之系統效能評估，可驗證本文所提出之以無線感測器網路為基礎之橋樑結構監測系統的可行性。

In this thesis a wireless bridge structure health monitoring system is presented. It is mainly using the wireless sensor network (WSN) technology to acquire and gather the raw structural and environmental parameters and to transmit the numerical data to the gateway (or namely the sink) through multi-hop relay. And then it further stores data in the back-end monitoring center for the professional staffs to analyze and study. Based on the proposed bridge system, thus, the monitoring efficiency of bridge structures could be improved, and then to further satisfy the goal of intelligent infrastructure.
　　In order to conform the requirement of interface consistency between the front-end sensors (such as tilt sensors, temperature sensors, etc.) and the sensor nodes of WSN, a interface circuit is designed to link with both. Finally, a prototype system is implemented and experimented to verify the feasibility of the proposed bridge monitoring system.
