基于Zigbee与GPRS网络数据传输技术的黄河河道断面冰水情多点自动监测系统设计与应用

The Design and Application of Automatic Multi-point Ice-water Monitoring System in the Yellow River Cross-section Based on Zigbee and GPRS Network Data Transmission Technology

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 method based on differences in the physical characteristics of the air, ice and water is a continuous on-line way to detect the vertical cylinders internal physical state of detected point. Due to the limitations of the tested points, this method does not implement a multi-point sampling data collected on the river section, unable to grasp the changes in the overall process of the disappearance and generate of ice of the river section. In this paper, we design a automatic monitoring system combines Zigbee and GPRS network data transmission technology based on the original ice-water detection system. The field test results show that the system achieve continuous real-time collection and transmission of multi-point data of the river section and meet the project demand for multi-point real-time monitoring of the river section.
