基于空气、冰与水物理特性差异的冰情检测方法是一种可以实现对检测点垂直柱面冰层内部物理状态连续在线检测的新型冰情检测方法.方法由于受测试点的局限,仅仅实现了对河道断面的单点取样数据采集,无法掌握河道断面整体冰生消变化的过程,在工程应用中受到限制.结合黄河冬季冰情现场实验的需求,在原有基于空气、冰与水物理特性差异的冰情检测系统基础上,融合了Zigbee和GPRS网络数据传输技术设计了一套黄河河道断面冰水情多点自动监测试验系统.现场试验结果表明,系统实现了对河道断面多点数据的连续实时采集和传输,可以满足工程中对河道断面多点实时监测的需求.
The ice detection method based on the difference of the physical characteristics of air, ice and water is a new ice detection method that can realize continuous on-line detection of the internal physical state of the vertical cylindrical ice in the detection point.Methods Due to the limitation of the test points, The single-point sampling data acquisition of the river channel section can not grasp the whole process of ice de-alteration in the river channel section, which is limited in engineering application.Combining with the requirements of the winter ice field experiment in the Yellow River, based on the original physical characteristics of air, ice and water Based on the difference of ice detection system, the paper combines the Zigbee and GPRS network data transmission technology to design a set of multi-point automatic monitoring and testing system for ice and water conditions of the Yellow River.The field test results show that the system realizes multi-point data Continuous real-time acquisition and transmission, to meet the engineering requirements of multi-point real-time monitoring of river sections.
