Intelligent monitoring system for industrialized aquaculture based on wireless sensor network

An intelligent monitoring system for the industrialized aquaculture was designed based on wireless sensors network, aiming to: avoid the negative effects brought by cable monitoring system; and improve the accuracy of the measurement and control of the environmental factors in industrialized aquaculture. Every breeding pond was set as one fixed cluster by small modifications of the protocol stack. A fixed cluster head was also set in every cluster by properly modifying routing protocol. All the modifications of protocol stack were helpful for reducing the amount of calculation in every cluster and saving energy significantly. According to combination of fuzzy and neural network algorithms, the controller accomplished the data processing. The controller generated corresponding control signals and realized the closed-loop control system. Further experimental tests showed that communications among the system ware realized reliably; and the requirements, such as the control precision of the temperature, the dissolved oxygen and the pH value, were perfectly met ±0.5℃, ±0.3 mg/L, and ±0.3 respectively. The application of the system can well meet the demands of modern industrialized intelligent aquaculture.
