基于雷达水位计的数据分析及其不确定度计算研究——以大城子水文站为例

摘要

In view of the limitation of traditional water level measurement method,error dispersion and uncertainty,non-contact radar water level meter is playing a more and more important role as a new water level measuring equipment.Based on the principle and characteristics of radar level meter,in Dachengzi hydrological station on the radar water gauge compared with artificial water meter analysis,hydrology information acquisition by artificial to mechanization,digital evolution,reduces the manual measuring frequency.In addition,maintenance should be strengthened in the use of the radar water level meter,when the radar water level measurement data error is larger,should be timely artificial retest.The use of non-contact radar water level meter can guarantee the intelligent collection of hydrological information data of similar hydrological stations.%针对传统水位测量方法的局限性、误差分散性及其不确定性,非接触式雷达水位计作为一种新型水位测量设备正逐步发挥着越来越重要的作用.文章结合雷达水位计的原理及特点,以大城子水文站为依托,通过雷达水位计与人工水位计的对比分析,将水文信息的采集由人工化向机械化、数字化演变,减少了人工测量的频率.此外,在雷达水位计的使用过程中,应加强维护保养,当雷达水位计量测数据误差较大时,应及时进行人工复测.非接触式雷达水位计的使用能够为类似水文站水文信息数据的智能化收集提供保证.
