Opening a new model of marine farming, 5G smart farming solutions promote high-quality development of the marine economy. From November 19th to 20th, the 6th China Large Yellow Croaker Cultural Festival, co-sponsored by the Ningde Municipal Party Committee, Ningde Municipal People s Government, China Fisheries Association and other units, kicked off in Ningde. China Mobile Fujian Ningde Branch (hereinafter referred to as CATL Mobile ) teamed up with Huawei and industry partners to jointly release the 5G Smart Farming solution to promote a new round of high-quality development of the marine economy. Large yellow croaker is a unique local seawater fish in my country. It has bright color and delicious meat. It is rich in protein, trace elements and vitamins and has a good tonic effect on the human body. Ningde is the largest large yellow croaker breeding area in the country. In 2021, Ningde City's annual large yellow croaker output reached 191,000 tons, accounting for more than 80% of the country's total aquaculture, with an output value of 6.918 billion yuan. In the 1960s and 1970s, due to overfishing, wild large yellow croakers were on the verge of extinction, making them scarce and expensive. The artificial breeding of large yellow croaker has gone through development stages such as ordinary cage culture, wind and wave resistant cage culture, cement pile and copper mesh enclosure culture, steel pipe pile and copper mesh enclosure culture, and large-scale breeding work ships. With the application of information technology in the marine field, maritime farming, coastal industries, maritime tourism, etc. have grown rapidly, and the demand for mobile communications in marine scenes has become increasingly urgent. In response to the network coverage needs of marine scenarios, Ningde Mobile and Huawei relied on 700M wide coverage capabilities and adopted 700M+2.6G multi-frequency collaborative networking to enhance uplink and downlink capacity. They selected high-altitude locations such as seaside and islands to build 5G base stations to achieve full coverage of 5G network signals at sea. Based on the 5G network, Ningde Mobile has teamed up with Huawei and industry partners to carry out digital and intelligent research and exploration on the industry pain points faced by offshore farming. At this year's Big Yellow Croaker Festival, many parties jointly released the 5G Smart Breeding solution. The 5G smart farming solution is aimed at owners of offshore fishing rafts and deep-sea equipment farming. It can help owners realize automation, intelligence, and wisdom in offshore farming, so as to achieve visibility, management, precise feeding, and good breeding, improve the quality of farming, and increase the input-output ratio. The current solution has implemented functions such as real-time monitoring of fish status , inspection of dead fish and debris and damaged fishing nets , oyster size measurement and water quality monitoring , and cleaning of underwater dead fish and debris . Real-time monitoring of the status of fish stocks: Underwater cameras are deployed in fishing raft cages and transmitted back to Ningde Mobile's smart ocean platform through the 5G network to centrally monitor the various statuses of fish stocks so that problems can be discovered in a timely manner and countermeasures can be taken to meet the needs of new business scenarios such as crowdfunding and breeding, fishing tourism, and live-streaming sales in the future. Inspection of dead fish, debris and damaged fishing nets: Deploy underwater robots to regularly inspect the sides and bottom of the fishing nets for damage, as well as debris in the cages to detect small holes or signs of damage in advance and take timely measures to avoid huge catch losses caused by large-scale damage to the fishing nets. At the same time, the video captured by the underwater robot can also be transmitted back to the background in real time through the 5G network. In the future, AI capabilities will be used to achieve unmanned automatic inspections. Oyster size measurement and water quality monitoring: Underwater robots can carry accessories such as laser rulers or water quality monitors, transmit data to the platform in real time through the 5G network, and use the platform's AI computing power to measure the size of aquatic products such as oysters and scallops, so that owners can timely grasp the growth of oysters and scallops. In addition, the water quality test facilitates owners to evaluate and select suitable breeding sites. Underwater dead fish and debris cleaning: If there are diseases, dead fish, and unclean debris at the bottom of the fishing drainage, it will greatly affect the water quality and spread the disease to other fish, causing greater losses; if the underwater robot finds dead fish during the inspection process, it can use the supporting mechanical arm/net tool to clean up the dead fish or debris in time. In the future, as AI capabilities gradually improve and mature, smart breeding solutions will be further enhanced to provide more intelligent functions. For example: AI is used to identify the size and quantity of large yellow croaker, and accurate calculations of fishing raft production and fish feed volume are implemented to achieve more accurate investment and output; AI is used to identify the hunger and disease status of large yellow croaker, and automatic feeding equipment and remote fish diagnosis hospitals are combined to improve the feeding quality of large yellow croaker and reduce breeding costs. During the Cultural Festival, Ningde Mobile and Huawei built an eye-catching 5G exhibition car with the theme of 5G Smart Ocean, which comprehensively demonstrated to the exhibitors Ningde Mobile's achievements in benefiting the people, developing industry, and good governance. The most eye-catching one is the 5G smart ocean management platform built by Ningde Mobile. Through the large screen in the exhibition hall, you can clearly see the real-time feed back images of fish schools captured by underwater high-definition cameras. 5G technology is making offshore, deep sea and far sea become fertile farmland and granary for the development of marine economy. Looking forward to the future, CATL will join hands with Huawei to continue to improve marine 5G network coverage and achieve excellence from existing ones. At the same time, we will work with industry partners to expand more 5G smart marine applications based on high-quality 5G network coverage and accelerate the realization of a new round of high-quality development of the marine economy
