本論文主要目的為研製與製作一套新式的微控制處理器智慧聯網 Fabry-Perot 干

端接收警報訊號。本防區系統使用光纜的單模光纖串聯四個波長各異的防區，
並將這些防區的光纖作為感測器架在柵欄上。四個防區使用分波多工的方式串
連並各自運作，彼此之間互不干擾。微處理器可即時偵測四個防區的干涉訊號

系統中自動設定的該防區閥值，系統除了在主機盒顯示入侵警示之外，還會自
動透過聯網傳送警報訊息到使用者手機端，藉此示警不在防區現場的擁有人。

The main purpose of this thesis is to develop and produce a new type of micro-control processor intelligent networking Fabry-Perot interferometer defense area type intrusion sensing system. This system can be divided into three parts, which are fiber Bragg gratings to form the optical path of the Fabry-Perot interferometer with four
defense zones, the microprocessor to analyze the signal and send the alarm through the network, and the mobile phone user terminal to receive the alarm signal. This defense zone system uses the single-mode optical fiber of the optical cable to connect four zones with different wavelengths in series, and an optical fiber cable is attached on fence for each zone.When the fiber cable is vibrated by intruders, the optical power reflected back to the receiver site carries the disturbance signal that is judged as an intrusion. The four defense zones are connected in series by means of wave division
multiplexing and operate independently without interfering with each other. The microprocessor can detect the change of the disturbance signal of the four defense zones in real time, and calculate the three signal parameters of each defense zone through the algorithm in the program, and automatically set the threshold value of each defense zone. When someone invades one of the defense zones, the three signal
parameters will exceed the threshold value for the defense zone already set in the system, and the system will automatically send an alarm message to the owners's mobile phone through the network to warn the owner.
