基于空气、冰、雪与水物理特性的差异,设计了适应高寒地区内陆河道冰雪情定点自动检测的传感器和数据采集系统设备.该系统被安装在黑龙江省漠河县北极村水位站黑龙江河道断面,进行了3个半月的冰雪情定点连续监测,获取了系统的黑龙江河道内部冰水情以与积雪深度现场数据.采集数据完整地反映了黑龙江河道冬季冰层和雪层生消变化过程,为分析高寒地区冬季冰雪情变化规律以及春季凌汛预警提供了科学的预测数据,并探索出了一种适合野外恶劣环境下工程应用的冰雪情检测方法和系统设备.
Based on the difference of the physical characteristics of air, ice, snow and water, sensors and data acquisition system equipment designed to automatically detect ice and snow spots in inland rivers in alpine region were designed.The system was installed in the section of Heilongjiang River at the water level station of Arctic Village in Mohe County, Heilongjiang Province , 3-and-a-half months of continuous monitoring of the snow and ice spots, access to the system of Heilongjiang River water and snow depth with snow depth data.The collection of data completely reflect the Heilongjiang River in winter ice and snow layer of birth and change process, This paper provides scientific forecast data for analyzing the law of winter and snow conditions in the alpine region and early warning of spring flood, and explores a method and equipment for snow and ice detection suitable for engineering applications under harsh field conditions.
