海上警戒浮标实时监控系统

为有效保护近海海底观测网观测安全,免受渔船拖网和抛锚等损坏的问题,设计了一套多警戒浮标(直径2.4~3.0 m)的实时监控系统,该警戒浮标可获取浮标本身工作状态,并能实时、动态、连续的将警戒浮标的运行状态发送到陆基岸站,实现对保护目标海域的实时监控,同时该浮标系统可进行扩充实现对海洋环境要素的观测。警戒浮标布设采用正多边形(三角形、正方形和正五边形等)预警保护方式,浮标以保护节点为中心等距布放,组网形成有效的海上保护围栏,保障海底观测系统的安全运行;供电系统采用太阳能电池和蓄电池组合供能方式,可保证在连续阴天的情况下警戒浮标系统运行100天。该警戒浮标技术已在东海海底观测网保护中成功示范运行6个月,该技术可为近海海底观测保护提供有效技术保障。

Real-time monitoring system of alert buoys for offshore observation

To effectively protect the safety of offshore seafloor observatory network from fishing boats trawl and droping anchor damage problems, etc., we designed a set of real-time monitoring system using multi alert buoys (2.4 ~ 3.0 m in diameter). Each alert buoy can record its working condition, and send the corresponding data to the land-based terminal real-timely, dynamically and continuously, so as to realize real-time monitoring of the protection targets in sea area. Meanwhile, the buoy-system can be expanded to conduct marine environmental observation. In order to protect the node effectively, the shape of the network is designed to be regular polygon (triangle, square and pentagon, etc.), and the buoy is located at the center of the node. The alert-buoy network forms an effective maritime protection fence to protect the seafloor observatory network. Power supply system, which consists of solar battery and storage battery, makes sure that the alert-buoy system can continuously work for 100 days even in cloudy weather. This alert-buoy technique has been successfully run as a demonstration for six months in the East China Sea seafloor observatory protection network. This technology can provide effective support for offshore seafloor observatory protection.
