The most commonly used monitoring methods for ship dynamic monitoring

At present, AIS system is still the most mature, commonly used and cost-effective monitoring means. This kind of monitoring method does not need to invest hardware equipment at one time, and the minimum cost can be controlled at several hundred yuan per month. It is a popular monitoring method.

At present, there are not many AIS monitoring systems available in the domestic market, and most of them are in the research and development stage of universities, such as Dalian Maritime University, Wuhan University of Technology Intelligent Transportation Research Center and Shanghai Maritime University, which are all developing and testing corresponding systems.

Foreign countries have developed quite well in this respect. Taking the AIS system of online ship operation as an example, the main features of realizing ship dynamic monitoring through AIS system are briefly explained: there are more than 20 coastal ports in China (such as Shanghai Tanggu, Tianjin Longkou, Penglai, Yantai, Weihai, Qingdao Lianyungang, Haikou, Zhanjiang, Nanjing Bay, Macau Zhuhai, North Point, Changsha, Wan Hong, Shantou, Shanwei, Xiamen Quanzhou, Hanjiang, Fuzhou, Songjiang, Wusong, Jiangnan, Tang Wei, Zhenjiang, Taiwan Province, etc. ).

Singapore, South Africa, Spain, Sweden, Syria, Turkey, Britain, the United States, Ukraine, and the United Arab Emirates can search through ports or ships, which has the search function and provides the historical navigation trajectory of ships.

There are map method and ship list method. Name of ship, ship type, IMO number, call sign, draft, length, width, depth, sailing date, classification society, owner, management company, latitude and longitude of ship position, and next port. The historical whereabouts of the ship (displayed in the form of curve) can be used to calculate the route mileage of the ship.
