自動鐵捲門監控系統之研究

Abstract

本文結合遙控自動捲門二態編碼及滾動碼技術，架構出一套整合性的自動鐵捲門監控系統，並利用單晶片實現之。傳統的二態捲門遙控系統有著密碼單調易被破解的風險，而滾動碼系統彈性低，無法隨使用者自定規格。綜合以上問題，本論文提出了一整合性的自動捲門監控系統，結合二態編碼的使用便利性及滾動碼技術的安全性，並應用無鑰進入系統之概念，且增加了可由使用者自定的變數，提高了此一自動捲門監控系統的彈性。 在人身安全部分，在系統中加入了紅外線偵測機制，可有效判斷當捲門落下時是否有人，避免造成人員傷亡，亦可有效監控是否有人闖入，增加了使用上的安全性。

In this thesis, we combine the two-state coding shutter and Keelog coding technique to establish a shutter monitoring system. There is a drawback of being monotone in the traditional two-state coding shutter system, and the Keelog shutter system is short of elasticity. To address these issue, we propose a new scheme in shutter monitoring system, it combine the facilitation of use in traditional two-state coding shutter system and the safety in the Keelog shutter system. We also apply the aspect of no-key entrance system on it, and add a function that user could decide the variable in coding to prove the flexibility of the shutter monitoring system. In the safety work, we add the infrared ray detecting system to decrease the unexpected events. It could recognize if people stand below the shutter when if falls.It could also increase the safety by detecing if someone barge in through the shutter.
