摘　　要：冬季河流湖泊冰盖表面的积雪深度监测是水文信息化领域的一项切实需求,基于空气、积雪和冰盖3种介质对红外光的传输特性差异,设计了一种可以连续实时对积雪深度进行定点检测的传感器。传感器及检测系统于2016年12月初在我国黑龙江上游漠河县江段进行了现场安装与实验测试,通过与传统对射式雪深检测传感器以及当地水文站人工测试结果对比,基于红外光反射特性的雪深检测传感器灵敏度更高,能更准确反映出积雪深度的变化过程,且具有体积小,布设安装方便等特点,为高寒地区野外恶劣环境下积雪深度的定点高精度检测提供了一种新的解决方法和技术装备。It remains urgent in hydrological information field for snow depth monitoring on the ice cover of rivers and lakes in winter.Based on the infrared light transmission differences in air,snow and ice,this paper developed a sensor which could achieve a real-time and continuous detection of snow depth.The sensor and data acquisition system were installed and tested in the upper reaches of Amur River in Mohe from the beginning of December in 2016.Compared with the traditional correlation snow depth sensor and manual measurement from local hydrological station,the snow depth sensor based on reflection characteristic of infrared light is more sensitive and can present the change of snow depth more accurately.Small in cubage and easy to install,the snow depth sensor based on reflection characteristic of infrared light provides a new solution and technical equipment to show the accurate depth detection in cold regions.
