Description

technical field [0001] The invention belongs to the field of perimeter security, in particular to a long-distance perimeter security positioning and monitoring device and method based on distributed optical fiber disturbance sensing and unmanned aerial vehicle linkage. Background technique [0002] Perimeter security is also called intrusion monitoring and fence monitoring. Traditional perimeter security mainly refers to physical defenses such as walls, fences, barbed wire, etc. Modern perimeter security mainly refers to high-tech systems that use intrusion detectors to replace human patrols. Common electronic pulse / tension fences, lasers / infrared Through-beam systems, power grids on high walls, microwave radar, etc. However, these modern perimeter security technologies generally have the characteristics of limited prevention distance, poor anti-electromagnetic interference ability, low sensitivity, and high power dependence. , The distance that needs to be guarded against...
