摘要
面向地表水域网格化、精细化在线监测的应用需求,针对传统监测浮标体积大、成本高和布设不方便等缺点,设计了一款地表水常规五参数小型化在线监测浮标系统。该监测浮标系统具有体积小、布设简单方便、太阳能自供电和搭载云平台等优点,通过4G网络接入云平台,可为地表水域常规五参数的网格化、精细化在线监测和应急环境监测提供成套监测系统。经过测试,系统整体功耗约为3 W,采样电路准确度可达到±8 mV,供电纹波在200 mV以内、电源转换效率达到75%以上,传感器数值漂移均在量程的2%以内,通信连续性好,可以在湖泊或河流等地表水域长时间稳定工作。
In order to meet the application requirements of gridded and refined online monitoring of surface waters,this paper designs a conventional five parameters miniaturized online monitoring buoy system for surface water in view of the shortcomings of traditional monitoring buoys,such as large volume,high cost and inconvenient layout.This new monitoring buoy system has the advantages of small size,simple and convenient layout,solar energy self-power supply and cloud platform.It accesses to cloud platform by 4G network.This new monitoring buoy system can provide a complete monitoring system for the gridded and refined online monitoring of the conventional five parameters of surface waters,and also provide advanced solutions for emergency environmental monitoring.After testing,the overall power consumption of the system is about 3 W,the sampling circuit accuracy can reach±8 mV,the ripple of the power supply circuit is within 200 mV,and the efficiency can still reach more than 75%.The sensor drift is kept within 2%of the range after long-term work,and the communication continuity is excellent.This new monitoring buoy system can work stably in surface waters such as lakes or rivers for a long time.
