Aquaculture monitoring system based on fuzzy-PID algorithm and intelligent sensor networks

According to the development needs of aquaculture modernization, the wireless sensor network (WSN) technology is introduced into the development of aquaculture monitoring system, which can effectively solve the problem of complex work environment, scattered monitoring locations, and high wiring cost in the aquaculture. The system uses CC2530 as the core to develop wireless sensor nodes which follow the ZigBee protocol, uses the data collection terminal with high-precision sensor to collect data of the environment for achieving real-time monitoring of aquaculture environment and uses the fuzzy PID control algorithm to process environmental parameters for improving the accuracy of test data. The management function of various sensor nodes is achieved based on embedded database. The system realized the real time measurement and control for the dissolved oxygen, temperature, pH and other parameters of the culture water, reduced energy consumption, reduced latency and increased intensification and intelligent level of aquaculture. The monitoring results have shown that this system is usefulness and efficiency and can meet the application requirement of monitoring environmental parameters in aquaculture.
