黄河万家寨水利枢纽水库冰情定点连续自动监测系统的设计与应用

The Design And Application of Continuous Auto-monitoring on Fixed-point System to Ice Conditions at Yellow River Wanjiazhai Hydro-junction Reservoirs

基于空气、冰与水的物理特性差异实现对冰水情连续自动检测的原理,作者设计、研制了适应高寒地区水电大坝冰情定点连续监测的冰水情自动检测传感器与信号采集系统,通过在黄河万家寨水利枢纽水库现场对冰情近4个月的冬季连续试验,获取了水库冰层内部系统的冰水情数据,采集数据客观反映了水库库区监测点冰层生消变化的规律,为确保引黄入晋工程的安全运行,也为高寒地区河道与水电大坝的冰情预警提供了一种可行的检测方法与设备.

Based on the theory that the physical characteristic differences of air,ice and water can monitor the ice-water conditions continuously,the Signal Collection And Continuous Auto-monitoring on Fixed-point System to Ice-water Conditions is designed and developed,which is adapted to the extremely cold areas.And the data of the inner system of ice-water conditions has been collected through four-month continuous winter-experiment at Yellow River Wanjiazhai Hydro-junction Reservoirs.The data reflects the formation and disappearing regulations of ice layer at the monitor points in reservoir area.It makes sure of the Steering Yellow River to Shanxi Project being operated safely,and the efficient method and equipment of detection being provided for the pre-warn of hydroelectric dams and watercourse of ice-water conditions in extremely cold areas.
