Intelligent alarm system based on vibration sensor of optical fiber and grating

Taking vibration sensor of optical fiber and grating into field of perimeter security, an intelligent adaptive alarm algorithm of optical fiber and grating was proposed, based on dynamic programming and difference algorithm The proposed algorithm can realize intelligent alarm for illegal intrusion, with the error alarm ratio of 0.5% and 1.6%. The intelligent alarm system could fulfill the requirements of diversity of perimeter security, developing the new prospects for appliment of optical fiber and grating.
