摘要
在明渠流量计算中,水位精度要求高,水位观测数据必须及时更新。这对水位观测数据的及时性和有效性提出了较高的要求,传统的人工测量已经不能满足当前需求。本文以德国希贝SEBAPULS雷达水位计为例,采用目标实时校准法,分析雷达水位计测量误差来源并进行校验,并通过编程将水位计测量值传输到上位机,实现水位数据的远程传输及自动化处理。
In the open channel flow calculation,the water level accuracy is required to be high,and the water level observation data must be updated in time.This puts high demands on the timeliness and effectiveness of water level observation data,and traditional manual measurement can no longer meet current needs.This paper took the German SEBAPULS radar water level gauge as an example,adopted the target real-time calibration method,analyzed the source of the radar water level gauge measurement error and performed verification,during which the measured value of the water level gauge was transmitted to the upper computer through programming,so as to realize the remote trans⁃mission and automatic processing of water level data.
