Abstract:

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.
