System and method for automatic adjustment of cages in deep sea culture based on marine data perception

Abstract

The invention discloses an automatic adjustment system and method for deep sea culture net cages based on marine data perception, including equipment floating platform and at least one single culture equipment, the equipment floating platform is equipped with a control machine room and wireless communication equipment, the single The breeding equipment includes a controller, wireless transmission equipment, marine environment sensing sensors and equipment status sensing sensors; the controller accepts control commands from the control room to control the rotation of the farming cages and moves up and down, left and right, and the marine environment sensing sensors and equipment status sensing sensors The sensor transmits the measured data to the controller through the wireless transmission device, and the controller transmits the sensor data to the control machine room. The present invention uses marine sensing data, according to the model algorithm, calculates through the fluid mathematical model, automatically adjusts the cage to obtain the maximum water intake and water flow velocity in the cage, improves the dissolved oxygen in seawater in the cage, reduces ammonia nitrogen, and improves the breeding environment in the cage .

Description

technical field [0001] The invention relates to an automatic adjustment device and method for aquaculture net cages, in particular to an automatic adjustment system and method for deep sea aquaculture net cages based on marine data perception. Background technique [0002] Marine shellfish are very sensitive to the amount of dissolved oxygen in seawater. The amount of dissolved oxygen is directly proportional to the growth rate of shellfish. Taking abalone as an example, it also grows for 22 months. Generally, 10 abalones grow in areas with low flow rate and dissolved oxygen. The flow rate and high dissolved oxygen area can produce 6 abalones, which is very different; the ammonia nitrogen is the opposite, the higher the content affects the growth of shellfish, and even leads to the death of shellfish organisms, the excretion of organisms, the corruption of food and dead abalones will lead to ammonia nitrogen in seawater content increased. The current state is to feel the ch...

Problems solved by technology

The current state is to feel the changes of the marine environment through experience, and to adjust the position and angle of the net cages for deep-sea farming by fishing boats. However, it is very inconvenient to drag the fishing boats, and the efficiency of dragging the net cages is very low, and the cost is also high. , while adjusting the information based on experience is not accurate and reliable
