Background technique

Because large and medium-sized fish ponds will be divided into several small fish ponds according to different fish species, each fish has different requirements for water temperature, depth, oxygen content, and PH value. At present, most of the fish ponds are mainly based on manual monitoring and management of the water environment, which results in a low degree of automation and low detection accuracy for the water environment. Unable to arrange personnel to take measures in time for the sudden situation in the fish pond, and cause a large number of fish to die and fish to be polluted. With people's concern about food safety and the demand for output, it is urgent to develop a set of intelligent control solutions for fish ponds with strong scalability, low price, easy management, simple operation and high efficiency. At present, some fish ponds use wired methods to transmit the data collected by fish ponds to the fish pond control center, but the price is high, installation and maintenance are difficult, staff scheduling and work efficiency are low, and there is no complete set of management systems for large and medium-sized fish ponds. system.

Under the framework of the Internet of Things, the present invention transmits the collected data of each fish pond to the background software on the PC of the fish pond control center in real time through the CC2530 sensor. For large and medium-sized fish ponds, this solution also supports each employee to interact with the fish pond control center through an Android phone. A relatively complete control system for large and medium-sized fish ponds has been realized.

The routing node first judges whether its next hop is the coordinator node. If it is a coordinator node, the routing node will transmit the data to the coordinator node, otherwise the routing node will transmit the data to the coordinator node located in the fish pond control center through multiple forwarding. After receiving the data, the coordinator node gives a response to the coordinator node to inform itself that it has received the data and transmits the data to the PC in the fish pond control center through the serial port in real time.

And generate routing topology for node death to make routing table changes. The management software checks in real time whether any employee finds abnormal water quality and whether there is a dead node. If an employee reports an abnormal situation, immediately inform the employee of the solution and deal with it. If there is a dead node, the routing table is updated according to the optimal principle, and the new routing table is sent to the coordinator node through the serial port for reorganization. The staff of the fish pond control center query and manage the data of each fish pond in real time through software. When the water quality parameters of a certain fish pond are abnormal, the system will issue a warning. After a warning occurs in the fish pond control center, the manager who manages the fish pond will be notified to deal with the problem accordingly.

As shown in Figures 4 and 5, when the staff in charge of the management of each fish pond inspect their respective fish ponds, they first receive orders from the fish pond control center in real time, and process them if there are orders. If there is no relevant command, download the latest data from the database on the background server through the management software installed on the Android phone, query the water temperature, PH value, water depth, water oxygen content and other data of each fish pond, and receive data from the fish pond in real time command from the control center.
