Recently, the Ministry of Natural Resources released a set of latest data: According to preliminary calculations, the gross marine product value of our country in the three quarters achieved 7.9 trillion yuan, an increase of 5.6% year-on-year, 0.4 percentage points higher than the growth rate GDP. This good trend of stability and progress not only conveys the vigorous development momentum of the marine industry, but also demonstrates our country's firm determination to accelerate the cultivation of marine productive forces and promote the high-quality development of the marine economy. In this journey towards maritime power, operators, as an important force in the construction of smart oceans, are technology as a brush to paint a magnificent picture of the transformation and upgrading of modern fisheries and the fortification of maritime safety production defense lines.
Policy empowerment lays a solid foundation for smart oceans. The strategic goal of "developing the marine economy, protecting the marine ecological environment, and accelerating construction of a maritime power" was clearly put forward in the report of the 20th National Congress of the Communist Party of China, which pointed out the direction for the construction smart oceans. Departments such as the Ministry of Natural Resources and the Ministry of Industry and Information Technology have successively issued documents such as the "14th Five-Year Plan the Development of the Marine Economy" and the "Action Plan for the Construction of Smart Oceans", which clearly require strengthening the construction of marine information infrastructure, improving the efficiency marine resources development and utilization, and enhancing the ability of maritime safety production supervision. Against this backdrop, operators have actively responded to the national call, relying on their own technological advantages, accelerated the layout of marine communication networks, building an integrated information system covering "sea, shore, and island", and providing a "digital base" for the construction of smart oceans .
5G “goes to sea” to build a smooth and efficient communication network Ocean communication is the “nerve center” the smart ocean, and 5G technology provides a key solution to solve the problem of maritime coverage. The operator extends 5G signals from land to the high seas through a networking model of “land sea”, achieving the communication goal of “excellent coastal experience, stable near-sea signal and wide far-sea coverage”. Chinacom relies on the integrated network of “Tiangong Satellite 5G”, and deploys low-orbit satellite communication nodes in key sea areas such as the East China and the South China Sea, building an integrated “sky-ground-space-sea” emergency communication system, ensuring that fishing boats can still maintain smooth communication under extreme weather. China has built more than 70 high-quality sea area base stations along the coast of Shanwei, adopting ultra-long coverage technology, which extends the coverage radius of 5 signals to more than 50 kilometers, benefiting more than 10,000 fishing boats and offshore operation platforms. China Unicom focuses on the Yellow Sea sea, and sets up 11 sea surface ultra-long coverage base stations in remote islands such as Qianliyan Island and Lingshan Island, supplemented by 1 shore-based base stations, forming a coverage network of “island ring chain”, effectively solving the problem of communication island of fishermen during operation.
Ensuring refined management of safe production in the fishery industry The vigorous development of the marine economy cannot be separated from solid guarantee of safe production. Operators build "one map of the sea port" through scientific and technological means, and through the integrated application of radar recognition, video monitoring, Beou positioning and other systems, the panoramic visual management of fishing ports, fishing boats and fishing rafts is realized, and the "smart brain" is installed for maritime safety production In terms of fishing port supervision, operators deploy high-definition cameras and AI recognition algorithms to automatically identify illegal fishing, illegal berthing and other behaviors, and transmit them back the regulatory platform in real time through 5G networks. For example, Zhejiang Zhoushan uses "5G AI" technology to implement 24- intelligent monitoring of 20 fishing ports in the jurisdiction, and the number of illegal fishing cases decreased by 60% year-on-year. In the field of fishing management, the ship-mounted Beidou terminal and AIS system are linked to track the position, speed and heading of fishing boats in real time, and the electronic fence technology used to delimit the operation area, and the system immediately triggers an alarm once the fishing boat deviates from the route or enters the dangerous sea area. Ningde, Fuj, achieved 100% coverage of dynamic monitoring of fishing boats by installing "5G Beidou" dual-mode terminals on fishing boats, and the accident rate sea in the past three years decreased by 45%. In addition, operators also promote the construction of "smart fish rafts", deploy IoT devices such as quality sensors and meteorological stations in aquaculture areas, and transmit data to the cloud for analysis through 5G networks, which helps fishermen to precisely regulate the aquulture environment. Sanya, Hainan's deep-sea aquaculture platform realizes automation in the links of feeding, aeration and water quality monitoring through "5G Internet of Things" technology, and the aquaculture efficiency is increased by 50% and the cost is reduced by 20%
