施工架無線監測系統之開發

Scaffold’s Safety Wireless Monitoring System Development

指導教授 : 曾惠斌

摘要


施工架為營造業最廣泛使用的臨時結構物,不管是在興建過程或是結構體使用與維護階段,都需要透過搭設施工架來方便施作人員進行施工或是支撐結構物。雖有專業人員進行結構檢核,但因憑藉著工人的經驗組立加上施工架數量眾多等原因,導致安全及品質管理不易,使得施工架災害頻傳。本研究案前幾屆已開發出數種有潛力應用於施工架監測之感測器與警報系統,可以成功於一定範圍內進行監測。 而本屆研究案將對前幾屆開發出的系統進行改良,將無線感測網路間的節點關係由星狀拓撲改為網狀拓撲,解決傳輸距離不足、節點間有障礙物阻擋等問題,藉此擴展無線感測網路涵蓋的範圍與增加網路的耐用性。 除了前幾屆開發的感測器之外,本屆另外開發出超音波測距儀與測角陀螺儀感測器,增加感測器的選擇性。這兩個感測器直接監測施工架破壞時幾乎必定產生變化的數值:與相連結構物間的距離、施工架立柱的傾角。與前幾屆不同在於這本屆改為所有感測器上皆有接警報器,如此一來便可以第一時間得知是哪個感測節點出了狀況。 最後本研究打造一套完整的監測系統,利用感測器量測現地施工架相關數據。隨後製作一接收基站,感測器將數據傳送至接收基站後基站得以將數據上傳至雲端資料庫。並撰寫一監測介面網頁,網頁會去擷取資料庫之數據以圖像化的方式呈現以供監測之用,如此一來施工人員就不會只有在警報器響時才能知道施工架的狀況危急,而是可以隨時監測施工架達到更好的預警效果。

In construction engineering projects, scaffolds are the most commonly used equipment in temporary structure during construction phase. Although the scaffolds will be examined, they are still mostly assembled by workers’ experience. Furthermore, there’re usually quite an amount of scaffolds in one construction site, it’s fairly difficult to maintain the quality of all of them, leading to accident caused by scaffold collapsing happens frequently. In the past years, this research has developed several types of sensors that could be put to use in building a scaffold alarming system. In this year, the research aimed to improve the system developed two years ago, changing the nodes’ topology from star topology into mesh topology, solving the problem of having insufficient transmitting range, and let the network be able to adapt to construction sites that are filled with obstacles between the nodes. This will result in having a more durable network. We added two types of sensors to the family : ultra-sonic distance measuring sensor and angle measuring gyro sensor. The former will be used to measure the distance between scaffold and the structure (that is attached to the scaffold); the latter will be used to measure the leaning angle of the scaffold. In addition, we attached an alarm device to every sensor in the network, so that when an alarm goes off the workers in site will immediately know which part of the scaffold went wrong. This research built an integrated monitoring system, using sensors to collect in-site data then passed them to a base station to upload them to a cloud database. At last we developed a monitoring website, showing data in the database in a real-time, dynamic and graphical fashion, so that the workers can understand the current condition of the scaffold.
