摘要
为解决水产养殖水质监测通信成本高、覆盖面不足、功耗高等问题,设计了一种基于LoRa无线通信的水产养殖水质监测系统。首先设计了菱形组网结构,确定了监测系统整体框架。然后确立了水温、溶解氧、浊度及pH值作为水质特征参数,进行了传感器选择、数据采集电路、USB驱动电路及LoRa驱动电路的设计。最后根据水质监测要求设计了数据采集软件流程、串口通信软件流程及LoRa自组网,并选用浮标固定节点的形式进行了应用实验。结果表明,该系统运行稳定,可以对水产养殖水质进行大范围监测。
In order to solve the problems of high cost,insufficient coverage and high power consumption of aquaculture water quality monitoring communications,an aquaculture water quality monitoring system is designed based on Lora wireless communications.Firstly,according to the characteristics of aquaculture waters,the diamond network structure is designed,and the overall framework of the monitoring system is determined.Secondly,the water temperature,dissolved oxygen,turbidity and pH value are established as the characteristic parameters of water quality,and the sensor selection,data acquisition circuit,USB drive circuit and Lora drive circuit are designed.Finally,according to the requirements of water quality monitoring,the data acquisition software flow,serial communication software flow and Lora ad hoc network are designed,and the application experiment is carried out in the form of buoy fixed node.Experiments show that the system runs stably,the wireless transmission distance radius is not less than 500 meters,and can monitor aquaculture water quality in a wide range.
