Research on safety early warning technology of liquefied gas carrier passing hub based on Beidou positioning

In this paper, the safety early warning technology of liquefied gas transport ship passing through the hub based on Beidou satellite navigation and positioning system is studied. With the development of China's shipping industry, especially the safety risks faced by liquefied gas carriers in the process of transportation are increasing day by day. How to improve transportation safety and early warning ability through advanced technical means has become an urgent problem to be solved. However, in the prior art, there is no technology for predicting the safety risk when the liquefied gas tank is transported by the liquefied gas carrier. In this study, a safety early warning model is studied, and the safety loss function is set by combining historical data, and the model coefficients are constantly adjusted, so as to carry out safety early warning. The early warning system has important theoretical value and practical significance for reducing the hidden danger of collision accidents in ship transportation and improving the informatization and modernization level of steam ferry transportation management. Through the application of Beidou positioning technology, this paper provides a new solution for safety monitoring and early warning of liquefied gas carriers, which is helpful to improve the safety and efficiency of ship transportation.
