仿海底洋流实验中水流动状况智能监控系统

Intelligent Monitoring Scheme for Water Flow in Imitation Ocean Current Experiment

在实验室做仿海底洋流模拟实验中发现利用水泵作为水循环装置时,仿海底管道中会产生较大的紊流与海底真实环境不符,为确定压电能量收集器的最佳放置区间,提出一种基于无线传感器网络的水流动状况监控策略.该监控策略通过芯片式加速度传感器对水循环廊道内的水流情况进行实时监测,并将监测到的水流数据通过Wi-Fi协议传送到上位机进行处理.实验利用水泵作为水循环装置,对规格为10 cm×10 cm×100 cm玻璃廊道内放置的3个三轴加速度传感器的采集数据进行分析.结果表明在距廊道入水口42~74 cm区间内水流较为平稳,未产生紊流现象,从而确定了压电能量收集器的最佳放置区间.

In the simulation experiment,it is found that when the water pump is used as the water circulation device,the large turbulence in the imitation seabed pipeline will not match the real environment of the seabed.Therefore,in order to determine the optimal placement range of the piezoelectric energy collector,this paper proposes a water flow monitoring strategy based on wireless sensor networks.The monitoring strategy uses a chip-type accelerometer to monitor the water flow in the water circulation corridor in real time,and uses the Wi-Fi protocol to transmit the monitored water flow data for analysis and processing.In the experiment,the water pumps is used as the water circulation device to analyze the data collected by three triaxial acceleration sensors placed in the glass corridor with the specification of 10 cm×10 cm×100 cm.The results show that the water flow is relatively stable in the interval of 42 cm to 74 cm from the inlet of the corridor,and there is no turbulence phenomenon.Therefore,the optimal placement range of piezoelectric energy collector is determined.
