臺灣博碩士論文加值系統

物聯網(Internet of Things， IoT)是未來資訊科技發展的主要趨勢，尤其是應用在預防經常發生地震豪雨的區域，預力地錨通常用於防止山坡的滑坡，以及由鋼索支撐吊橋的橋面，持續監控地錨與鋼索的應力是非常重要的。對於防止滑坡與吊橋的災害發生，以每年一次檢查的週期是不夠的，因此，即時遠端監控系統是必要的。這項工作裡，無線感測網路包含了區域性無線Zigbee通信與GSM應用於遠端檢驗山坡狀態與監控吊橋應力。鋼纜或地錨的應力是使用一顆負荷元與ADC做為量測。測量的數據透過區域性的Zigbee無線網路收集，在將收集完畢的數據透過GSM通訊傳輸到伺服器做為其他應用。本論文在台灣高雄茂林的多納吊橋建立了一套測試系統，在這項工作中開發的技術還可以應用到其他的環境監測，家庭護理與健保

Internet of things is a main trend of future development of information technology, especially, in the applications of disaster prevention for rainy and earthquake-prone areas. A pre-force ground anchor is usually used to prevent the landslide of a hillside as well as the steel cable to support the deck of drawbridge. To keep and monitor the force on a ground anchor and the stress of steel cable are very important. An annual inspection of the force is not enough to prevent the occurrence of disaster of landslide or drawbridge breaking. Hence, a real-time remote-monitoring system is necessary. In this work, a wireless sensor network that includes a local Zigbee network and a global system of mobile (GSM) communication is applied to remotely monitor status of drawbridge or hillside via the stress inspection. A load-cell sensor with a 24 bits analog-to-digital converter are used to measure the force or stress on the ground anchor of steel cable, respectively. The measured date is collected via a local wireless Zigbee network. The collected data is transmitted to a server through GSM communication for other applications. A demo system has been set up at Dona drawbridge of Maolin Kaohsiung of Taiwan. The technology developed in this work can also applied to other environment monitoring, family Care and health care
