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.

Abstract in Chinese

针对水产养殖非线性与大时滞的特点,本文提出了基于LoRa通信技术的水产养殖环境监测系统设计,系统集传感器节点、溶解氧调控节点、LoRa通信网络、上位机平台于一体,实现了数据的实时监控、存储与共享。PLC智能控制器对传感器采集到的环境参数进行处理并通过变论域模糊 PID 算法对水中溶解氧浓度进行智能调节。该监控系统在面积为110*120平方米的鱼塘进行了实验,试验结果表明:该系统可实时获取温度、pH 值、溶解氧等养殖环境参数信息系统,优势是测量精度高,数据传输稳定可靠,满足了水产养殖智能化管理的需要.
