张家坟水文站是密云水库白河入库控制站,担负着密云水库入库水量的观测任务.基于不确定度评定与相关性计算等方法,对该水文站遥测水位与人工观测水位数据的误差进行研究.结果表明,遥测水位与人工观测水位数据的相关系数达到0.99以上,点距分布均匀,基本呈线性关系,误差在水文规范允许误差范围内,基本趋于正态分布.遥测水位系统误差的随机不确定度在±1 cm的规定控制误差范围内,时钟误差小于±0.5 min,均符合有关规范要求.分析成果说明了遥测技术的有效性和实用性.
Error Analysis of Telemetry Water Level Based on Uncertainty and Correlation Calculation
Zhangjiafen Hydrological Station is the a control station for the inflow of the Baihe River in Miyun Reservoir,which is responsible for observing the inflow volume of the Miyun Reservoir.Based on methods such as uncertainty and correlation analysis,the error between telemetry and manual measurement of hydrological data at this hydrological station was studied in this paper.The results showed that the correlation coefficient between the telemetry data and the manual observation data series reached above 0.99,the point distance distribution was uniform,and the relationship was basically linear.The error was within the allowable error range of the standard and tends to a normal distribution.The error and random uncertainty of the telemetry water level observation system were within the specified control error range of±1 cm,and the clock error was less than±0.5 min,all of which complied with relevant regulatory requirements.The analysis results demonstrated the effectiveness and practicality of telemetry.
