Abstract
In view of the nonlinearity and large time delay characteristics of the aquaculture, this paper proposes an environment monitoring system based on low long range (LoRa) communication technology. The system integrates sensor nodes, dissolved oxygen regulation node, LoRa communication network and personal computer (PC) platform to realize real-time monitoring, storage and data sharing. The environmental parameters were processed by programmable logic controller (PLC) intelligent controller, in which, the dissolved oxygen was adjusted with the variable universe fuzzy PID algorithm. The system was tested in a fish pond with an area of 110*120 square meters. The results show that the system can obtain temperature, pH and dissolved oxygen in real time and it has the advantages of high measurement accuracy, stable and reliable data transmission, and can satisfy the needs of aquaculture intelligent management.
