RQ30D多传感器雷达在线测流系统数据可靠度分析
|
摘要
为分析RQ30D(多传感器雷达在线测流系统)数据的可靠度,在自然环境下,选择尽可能满足重复性条件的监测数据,根据《河道流量测验规范》中流量测验成果精度评定的方法,对数据的随机误差分布形态及95%置信水平下的随机不确定度进行分析。分析结果表明,该系统数据在高、中、低各水位级的随机误差呈正态分布,不确定度也满足单次流量测验允许误差的要求。
In order to analyze the data reliability of RQ30D multisensor radar online discharge measurement system. In natural environment, the paper selects monitoring data, satisfying the repeatability condition as far as possible. According to the method of accuracy evaluation of discharge measurement results in Code for liquid flow measurement in open channels, it analyzes the random error distribution of data and the random uncertainty at 95% confidence level. The analysis results show that the random errors of the system data at high, medium and low levels are normal distribution and the uncertainty also meet the requirements of permissible errors in single discharge measurement.
