雷射監測系統自動通報適用性評估與地滑應用

坡地的開發固然為非不得以的手段，然如果不認識坡地、保護坡地、建立民眾以及讓政府對坡地上的預警功效加以重視以及瞭解，也是枉然。本研究在控制成本為前提下，提升雷射監測設備的自動化、人性化等需求。本研究利用Visual Basic設計其人機介面（程式），由於雷射監測系統與本程式之間還需I/O埠，本研究假設其I/O埠為單晶片模組，因此在程式設計上，假設其訊號來源為單晶片模組。此外，為了瞭解雷射監測系統的基本性質，本研究亦針對雷射的基本性質進行實驗，其中所使用的半導體雷射（Semiconductor Laser）有一般型：650nm波長，初始輸出功率為1.75mW 0.05 mW；增強型633nm波長，初始輸出功率為5.7mW 0.05 mW雷射兩種，在距離上分別針對50公尺以及100公尺進行實驗。根據本研究的成果指出，增強型雷射的光源擴散幅度較小；而雷射最長可啟動Switch Box的距離，本研究訂定其有效距離係數為2。而本研究所設計的人機介面經過測試證實，當本程式偵測到訊號產生變化時，能正確的將訊號透過電子郵件發送至指定收件人，並且可由手機上網（GPRS）收信瞭解其內容以達到人性化、自動化、使用成本低廉的目的。除此之外，亦可透過週期性監測瞭解雷射監測系統的訊號正常與否。

In this study, consider traditional or new tech monitoring system. To improve the Laser Monitoring System automatic warning, cost down and application is the purpose of this study. So the purpose of improving the system is to make it more automatic and human accesible. That should be started from visual basic program design. In this study, assume between the Laser Monitoring System and the VB program of I/O port is MCS-51 module. So when design the signal input of program will be MCS-51. In this study not only design a program, but also test the laser basic function. In the test there are 2 kind of semiconductor laser. One of them is 650nm wave-length and 1.75mW 0.05 mW (standard) power; another is 633nm wave-length and 5.7mW 0.05 mW (enhance) power. The test will be in two different distance in 50M and 100M respectively. The result of this study, enhance laser convergence is better than standard laser. The most distance of started switch box factor is above 2. When the program detects that the signal is change. It can then send a “warning” letter to the mail list. The receiver can go to internet from mobile phone by GPRS to receive the “warning” letter. Other wise it can be sent to a period monitor. At last this automatics warning system maintain cost is inexpensive.
