Design of Aquaculture Water Quality Monitoring System Based on LoRa Communication Network Technology

Abstract

Using LoRa communication networking technology, an aquaculture water quality monitoring system is built, which solves the problems of high communication cost, insufficient coverage and high power consumption of current aquaculture monitoring methods. Firstly, according to the characteristics of aquaculture waters, the rhombic network structure is designed, and the overall framework of the monitoring system is determined. Secondly, the system hardware is designed, the water temperature, dissolved oxygen, turbidity and pH value are established as the characteristic parameters of water quality, and the power supply voltage conversion circuit and data acquisition circuit are established. Finally, according to the requirements of data acquisition and monitoring, the software flow, LoRa Ad-hoc network and cloud monitoring platform are designed, and the application experiment is carried out in the form of buoy fixed node. Experiments show that the system is stable, and the wireless transmission distance radius is more than 350m. It can monitor the water quality of aquaculture waters in a wide range, and this method is of practical application value.
