电阻元件特性和包含电阻元件的电路分析是电路理论中最基本的分析内容和电路分析方法之一.根据冰水情工程检测中的客观环境条件,利用空气、冰与水的等效电阻随温度变化所具有的数值差异这一特点,将电路理论中电阻电路分析方法应用于冰水情工程检测中,提出了将检测环境分层处理的思路,应用线性电路理论中电阻分压的原理,通过对各分层介质等效电阻的检测、计算,反推出被检测介质的物理形态,进而实现对冰层内部物理状态、冰层厚度与冰下水位连续监测的目的.基于这一新的检测原理,作者研制成功新型R-T(电阻-温度梯度)冰水情自动检测传感器及其检测系统,并在南极海冰观测、黄河中上游河道冰水情定点连续监测、高寒地区河道与水电大坝冰情预警与水文信息自动测报等多个重大工程领域获得应用,为解决南极科学考察、黄河冰凌灾害预报、高寒地区河道、水电大坝、湖泊等领域冰情自动监测难题提供了一种新的检测方法与实现途径.
The characteristics of the resistance element and the circuit analysis including the resistance element are one of the most basic analysis contents and circuit analysis methods in the circuit theory.According to the objective environmental conditions in the ice water project detection, the equivalent resistance of air, ice and water is calculated with the temperature The value of the change has the characteristics of the circuit theory of the resistance circuit analysis method used in ice and water project detection, the detection of the environment stratified treatment ideas, the principle of linear resistance theory, the partial pressure through the principle of Based on this new principle of detection, calculate and deduce the physical form of the medium to be tested, the physical state of the ice layer, the thickness of the ice layer and the ice level under the ice can be monitored continuously. , The author successfully developed a new RT (Resistance-Temperature Gradient) ice water automatic detection sensor and its detection system, and in the Antarctic sea ice observation, continuous monitoring of ice and water conditions in the middle and upper reaches of the Yellow River, ice and dam in the alpine region Early warning and hydrological information automatic forecasting and other major projects have been applied to solve the Antarctic scientific expedition, the Yellow River ice disaster forecast, The field of cold regions rivers, hydroelectric dams, lakes and other automatic monitoring ice conditions puzzle provides a new method for detecting and implementation approach.
