Shipping and water transport are among the most widely transported in the world and one of the earliest applications of satellite navigation.
At present, most of the various types of ships traveling in the world's oceans and rivers and lakes are equipped with satellite navigation terminal equipment, which makes sea and water transportation more efficient and safe. For China's fishing vessels and coastal defense systems, Beidou satellite navigation system has already provided the function of providing navigation and positioning, monitoring and tracking, and transmitting alarm information for water navigation vessels under any weather conditions. At the same time, the short message communication function unique to the Beidou satellite navigation system also provides a guarantee for the safe operation of fishing boats.
China Weapons Group Northern Information Control Group Co., Ltd. launched a series of application systems suitable for use in the fishery industry during the Expo. Mr. Xu introduced the “Zhoushan Fishery Monitoring System†to the reporter. This system consists of the ship Beidou navigation communication system, the “Jingzhongtong†satellite communication system, and the integrated communication command and dispatch system, which can realize the continuous forwarding of information and can Offshore production operators and their affiliates provide ship-to-shore and inter-shipment SMS intercommunication services between various communication networks.
During the long journey, the ship's staff paid special attention to weather conditions and sea breeze waves. In the Beidou application system displayed by the China Science and Technology Exhibition Group, the China North Industries Group also launched the “Beidou Meteorological Sounding Application Systemâ€, which has both the Beidou satellite navigation system and the “Beidou†meteorological communication terminal, which has been applied in meteorology. Monitoring and release of monitoring and meteorological information, providing functions such as atmospheric wind speed, water vapor content, sea breeze waves, lightning observations and warnings.
In the past 10 years, Beidou navigation system has produced positive effects on marine fisheries. Yang Baofeng, director of the China Satellite Navigation and Positioning Application Management Center, said that it was difficult to promote fishermen at the beginning, and now Beidou has become a "protective god" for fishermen. Especially in the case that the marine environment is very complicated now, the Beidou Marine Fishery Location Information Service Center can obtain the location information of the relevant fishing vessels in real time when the fishing boat encounters the dangers such as weather, sea conditions and fires, and organize rescue in time. "The sea areas where fishing vessels are driven have no-fishing areas or national maritime boundaries. When the borders are exceeded, they will automatically alarm in the form of short message communication to avoid unnecessary losses to the fishing boats."
At present, nearly 40,000 sea-going fishing vessels in the country have installed the Beidou satellite navigation system terminal. According to the statistics of the Beidou authorities, the number of maritime users of the Beidou marine fishery integrated information service has reached 40,000; the number of mobile phone users who have opened the Beidou terminal and mobile phone short message intercommunication service has exceeded 70,000, and the monthly volume of text messages has reached 700,000.
Mr. Xu told reporters that the Beidou navigation terminal has been installed in the fishing boats operating in the East China Sea and the South China Sea. The number of fishing vessels in the East China Sea can reach more than 8,000. These terminals can provide ship monitoring, emergency rescue, policy release, and fishing vessel entry and exit management services to the fishery management department. They can also provide navigation and positioning, distress and rescue, navigation notices, weather, waves, and fish market conditions to marine fishing vessels. The short message service between ships and ships, ships and shores has improved the level of safe production support for fishing vessels in the fisheries management department.
At the site of the China Science and Technology Fair, the text board of the “Digital Fishing Vessel System†and the “Border Sea Defense Monitoring System†in front of the booth of the China North Industries Group was also the result of the Beidou application system in fishery applications. Among them, the “digital fishing vessel system†includes not only the positioning and navigation system, the route and navigation planning subsystem, but also the reef and collision avoidance subsystem, which provides guarantee for the safe navigation of the vessel.
The “Buihai Anti-Monitoring System†integrates the command and control system, the prevention and control system, the communication and dispatching system, and the support system, and adopts monitoring means such as Beidou positioning equipment, fixed monitoring station system, mobile monitoring system, air monitoring system, and perimeter alarm system. It constitutes a three-dimensional defense system. Complete system installations can monitor, track and record illegal cross-border targets, and ship crews can transmit relevant image, location and alarm information to higher authorities when an unexpected situation is discovered.
Mr. Xu explained that the greatest significance of these systems is that they can “cooperate†with multi-level Internet centers to complete the functions of reporting intelligence, generating tasks, analyzing tasks, and generating plans from the bottom up, and can also complete the decision of the head according to this, and Real-time dynamic completion of top-down command release and deployment power. From this point of view, Beidou's application system in shipping and coastal defense can reduce maritime disputes and safeguard China's maritime rights and interests.
Beidou can provide precise navigation services for fishing boats
