Optical fiber underwater intelligent fence system and application thereof

Abstract

The invention relates to an optical fiber underwater intelligent fence system and application thereof. The system includes a monitoring terminal, a transmission optical cable and an optical fiber intelligent fence; the monitoring terminal is located above water; the optical fiber intelligent fence is located under water; the transmission optical cable is connected with the monitoring terminal and the optical fiber intelligent fence; and the optical fiber intelligent fence comprises a vibration sensing optical cable subsystem, a fence and a fixing device, wherein the vibration sensing optical cable subsystem is fixed on the fence and is a passive device. Parts of the optical fiber underwater intelligent fence system are entirely composed of passive devices, and therefore, when the system operates, no current passes through, and no electromagnetic waves are radiated, and the system will not be subject to electromagnetic interference, and electric leakage, short circuiting, heat emission and the like can be avoided, and the system can work for a long term in water and is free of risks. The monitoring terminal which is located above water solely requires low-power electric energy supply; the parts under water transmit optical signals all through optical fiber devices and optical fiber cables, and therefore, energy loss is small, and the parts can work under water for a long term in a range of tens of kilometers without external energy supply required.

Description

technical field [0001] The present invention relates to an underwater perimeter security system and its application, in particular to an optical fiber underwater system whose underwater part does not contain any electronic components and does not require power supply, so it is intrinsically safe and can be applied to various water-facing areas. Next, the smart fence system and its application. Background technique [0002] With the continuous development of terrorist activities from land to underwater, the detection, identification, positioning, and early warning of underwater intrusion targets have become a new focus of attention. In recent years, various technologies and equipment for detecting underwater targets have emerged. [0003] The existing underwater monitoring system, whether it is a sensor, a data acquisition system, or a data transmission system, is mostly composed of electronic components and requires power supply. These electronic components operate for a lo...
