Aquaculture monitoring system based on intelligent sensor network

Accurate monitoring of aquaculture environmental parameters can provide technical decision-making for scientific management, and it is of great importance to improve the level of intensive cultivation. Most of the traditional monitoring systems are wired, and most of them use field bus and distributed control bus. However, their shortcomings are obvious: wiring is cumbersome, which is not conducive to system layout changes and maintenance, and cannot be widely applied. This control method also has the problems of vulnerable lines and corrosion, poor system reliability, high maintenance costs, and limited remote monitoring. The use of a wireless sensor network to build a monitoring system has the advantages of easy deployment and low cost, can effectively achieve the collection and transmission of environmental information, and timely adjust management strategies. It has been widely used in environmental monitoring, precision irrigation, greenhouse control and other fields. The rapid development of wireless networks makes long-distance data transmission widely used. The unique advantages of wireless sensor network networking, such as flexibility and convenience, wide coverage, make it a digital, networked, distributed local or remote real-time dynamic water quality of intensive aquaculture. Regulatory and environmental monitoring are increasingly valued. Aquaculture monitoring systems play a very important role in aquaculture.

According to the characteristics of aquaculture production and its monitoring needs, the aquaculture monitoring system CC2430 wireless communication module is used to form a data collection terminal, real-time monitoring of environmental factors such as temperature, dissolved oxygen, and pH values ​​that are closely related to aquaculture, and the use of fuzzy PID control technology for monitoring. The data deviation is processed. Through the control of the aerators, solenoid valves and other implementing agencies, the aquaculture ponds are automatically adjusted to improve the control accuracy.

The aquaculture monitoring system, based on the investigation of the specific needs of aquaculture environmental monitoring systems and the problems that are difficult to solve, designs an aquaculture environmental information monitoring system based on CC2430 and fuzzy PID control technology based on intelligent sensor network technology. The system has low cost, no wiring, and flexible networking. It overcomes the problems in the traditional aquaculture environment parameter monitoring system and provides a useful exploration for the application of wireless sensor network technology in the field of industrial aquaculture environmental parameter monitoring. The experimental results show that the system can meet the needs of centralized monitoring and unified management of multiple aquaculture ponds.
