极区海冰影像自动监测系统的设计与试验

Design and experimental use of sea ice image automatic monitoring system in the polar region

随着全球气温上升,北极海冰的消融加速,北极航道的开通成为可能,极区海冰监测对船舶航行安全及无人冰站有着重要意义。设计低功耗、耐低温且工作稳定可靠的极区海冰影像自动监测系统,集成耐低温的串口摄像头,实现海冰表面形态和浮标运行状态的监测;增加加热模块以解决极区低温环境下摄像头无法正常采集图像的问题;基于铱星9523研发了针对大量数据的传输策略,实现了图像数据的远距离传输;以蓄电池为储能装置并配置太阳能板补充电能。监测系统在中国第九次北极科学考察中进行了安装并在第十一次北极科学考察中进行了优化和升级,结果表明该系统在极地低温恶劣环境中运行稳定,可靠性强,可以长期工作。

As the global temperature rises and the melting of Arctic sea ice accelerates,the opening of the Arctic waterway becomes possible.The monitoring of polar sea ice is of great significance to ship navigational safety and unmanned ice stations.We designed a low power,low-temperature-resistant,stable,and reliable polar region sea ice image automatic monitoring system.The system integrates a low-temperature-resistant serial camera to monitor the sea ice surface shape and the operating state of the buoy;we added a heating module to cope with the low temperatures of the polar region.The problem is that the lower camera cannot collect images normally.Based on the Iridium 9523,a transmission strategy for large amounts of data has been developed to realize the long-distance transmission of image data.The storage battery is used as an energy storage device,and solar panels are configured to supplement electrical energy.The monitoring system was installed during 9th Chinese National Arctic Research Expedition and optimized and upgraded in the 11th research expedition.The results show that the system is stable and reliable in the extreme low temperature and harsh environment,and can work for a long time.
