摘要
在土壤冻融的热物理过程中,土壤中冰和水随着温度变化产生不同电阻,并且在数值上有明显的差异。基于这一特性,文章设计了电阻式冻土传感器,通过感应元器件、信号采集、信号转换处理和终端机等组件,研制了DOZ-1型电阻冻土自动观测设备。通过与TB1型人工冻土器观测资料对比分析,结果满足冻土自动测量技术要求,该仪器可应用于冻土自动观测站,代替人工观测。
Different resistances are produced by the ice and water in the soil in the thermophysical process of soil freeze-thaw as the temperature changes and there is a significant difference in value.Based on such characteristic,the resistance frozen soil sensor is designed and the DOZ-1 resistance frozen soil automatic observation equipment is developed by induction component,signal acquisition,signal conversion processing and terminal.Through the comparison and analysis with the observation data of TB1 artificial frozen soil device,the results meet the technical requirements of automatic measurement of frozen soil.The instrument can be used in frozen soil automatic observation station instead of manual observation.
