Description

Shipborne high-adaptability multi-mode fishery-win identification and intelligent sorting integrated device and operation method thereof Technical Field The invention relates to the technical field of ocean fishery automation equipment, in particular to an automatic sorting device for fishery gains, which is suitable for ship sailing conditions, and particularly aims at the technical fields of high salt spray corrosion protection, continuous mechanical vibration inhibition and flexible sorting of various fishery gains in a shipborne environment. Background In the ocean fishery ship operation system, real-time sorting treatment of the fishery gains is a key node for connection fishing and processing, the operation efficiency and accuracy of the ocean fishery ship operation system not only directly influence the connection efficiency of the subsequent refrigeration, processing and storage and transportation processes, but also determine the overall economic benefit and the resource utilization rate to a great extent. The total amount of 2500 fish in the existing ocean fishing vessels in China is over 200 ten thousand tons, and along with the expansion of the fishing scale of ocean fishing industry and the improvement of the resource development intensity, the improvement of unit operation efficiency and the reduction of operation cost through equipment upgrading are urgently needed, and the ocean fishing industry is promoted to be intelligent and intensive. However, the current ocean fishery still widely adopts a traditional manual sorting mode, the mode depends on visual identification and manual sorting of operators, the processing capacity per hour is only 150-200 kg, and the sorting misjudgment rate is as high as 8% -12%, so that the labor cost is more than 40% of the total fishing processing cost. The low-efficiency operation mode has high labor intensity and high manpower consumption, is difficult to adapt to the high-frequency and long-period operation demands under the background of large-scale fishing of ocean vessels, and becomes a core bottleneck for restricting the improvement of the ocean fishery productivity and the optimization of the benefits in China. Although some enterprises in recent years try to introduce an automatic sorting system to replace manual operation, and expect to improve sorting efficiency and accuracy by means of technologies such as machine vision, sensor identification, mechanical arm operation and the like, the conventional automatic equipment still faces a plurality of challenges in practical application of ocean vessels. The ocean vessel operation environment has the typical characteristics of high salt fog, high humidity, strong corrosiveness, continuous mechanical vibration and the like, and most of the existing equipment is designed for land factory scenes and lacks adaptability to ocean complex sea conditions. In long-term offshore operation, the equipment failure rate is high, the failure rate of part models exceeds 30%, the continuity and stability of the sorting system are seriously affected, and the maintenance frequency on a ship and the spare part storage cost are increased. In addition, the price of a single imported high-end sorting device is generally more than 120 ten thousand yuan, the maintenance period is long, the external dependence degree is high, and strategic safety risks exist. The independent research and development of the intelligent equipment level of localization and the reduction of the dependency of foreign equipment become an important task for guaranteeing the safety of the ocean fishery industry chain in China. In terms of functional adaptability, the traditional equipment has obvious limitations when facing to a mixed fishing scene of various fishery gains. Squid is easy to damage due to soft structure, mackerel is easy to drop due to surface scales, saury is easy to be blocked in a conveying link due to slender body state, and different fish-catching species provide differential adaptation requirements for sorting paths and conveying modes. The existing equipment generally has a fixed structure and single recognition logic, and lacks dynamic adjustment capability, so that the execution part needs to be frequently stopped and replaced in the operation process, the operation continuity is interrupted, and the overall operation efficiency and economic benefit of the ocean vessel are seriously affected. Based on the industrial upgrading requirements, the technical adaptation challenges and the strategic safety considerations, the invention develops the shipborne ocean fishing catch high-efficiency automatic sorter device with completely high adaptability and innovative performance. The device integrates a multi-sensor fusion recognition system (the recognition accuracy is more than or equal to 98%), a self-adaptive damping structure (the vibration attenuation rate is more than or equal to 85%) and a high protection level sealing design (the
