安徽省自动测流系统比测研究及实践

Analysis and practice on comparative measurement of automatic flowmeasurement systemsin Anhui Province

自动测流系统作为现代化测流设备,在安徽省逐步推广应用。为适应水文现代化建设要求,解决流量自动监测问题,通过明确比测方法与应用标准,对安徽省自动测流系统进行分析。以高坦站点流速雷达波与天长站垂直式声学多普勒流速剖面仪为例,通过线性回归、分段线性回归方式建立自动监测流量与人工实测流量关系,精度评定结果满足规范要求,可投入使用。总结了自动测流系统应用经验,提出思考与建议,对自动测流系统推广具有借鉴意义。

Automatic flow measurement system is gradually being promoted and applied in Anhui province as an updated flow measurement.In order to meet the requirements of hydrological modernization,solve the problem of automatic flow monitoring,analysis the comparative measurement of automatic flow monitoring in Anhui Province,determining comparative measurement methods and application standards.Picking point velocity radar wave of Gaotan station and Vertical ADCP of Tianchang station to demonstrate practical results.Use the linear regression and segmented linear regression methods to bulid the relationship of automatic and manually measured flow rate.The accuracy evaluation results met the standard requirements and can be put into use.Summarize the application experience of automatic flow measurement systems,propose the idea and suggestion which has reference significance for the promotion of automatic flow measurement systems.
