Abstract

The invention provides a deep and far sea area foreign matter invasion monitoring method based on an intelligent optical fiber barrier net, and belongs to the technical field of structural intelligent health monitoring. Distributed optical fiber sensing elements are designed according to geometric dimensions and surrounding marine environments of islands or platform facilities in jurisdiction in deep and far sea areas, butterfly-shaped optical fiber sensing networks and sizes of inner elliptical rings of the butterfly-shaped optical fiber sensing networks are designed according to enemy ships or large biological characteristics around the sea areas, the butterfly-shaped optical fiber sensing networks are enabled to suspend in the sea, and a plurality of butterfly-shaped optical fiber sensing networks form an optical fiber barrier net. And a traction cable with a built-in transmission optical fiber lead terminal is connected to distributed optical fiber demodulation equipment in a selected offshore observation room to form a monitoring system. According to the intelligent optical fiber barrier net provided by the invention, a demodulation device and a signal analysis processing method are combined, and an unmanned, active and real-time on-duty continuous monitoring technology is provided for intrusion identification of peripheral foreign matters in deep and far sea islands, platform facilities and the like.

Description

Technical field [0001] The present invention belongs to the field of structural intelligence health monitoring, relates to a far-reaching marine intrusion monitoring intelligent optical fiber sensing test method. Background [0002] At present, the maintenance of China's maritime rights and interests mainly depends on the coast guard patrol mode. This approach will greatly rely on cruise frequency, range and the marine combat experience of the cruisers. How to truly realize the active and effective maintenance of national maritime rights and interests requires the construction of a normalized on-duty marine rights protection cruise mechanism and an all-weather and timely support force, so as to realize the sea areas owned by unmanned control. Especially for the deep sea far from the land, it is of great significance to build a real-time continuous on-duty control technology. Under the background of the rapid development of modern intelligent and information technology, we can ...
