The collected and processed data cover ID, terminal number, time, longitude, latitude, ship speed, swing angular velocity, current ship stability coefficient, ship stability assessment result, stability coefficient of current recording point, 1-hour stability coefficient of current sea area, 3-hour stability coefficient of current sea area, sea area stability assessment result and other relevant metrics, to generate early warning data for the stability assessment of ship navigation waters. Real-time monitoring of parameters such as ship speed, swing angular velocity and ship stability assessment result enables timely detection of ship instability, accident prevention and guaranteed navigation safety. Based on the sea area stability assessment results, early warnings for potential severe weather and sea conditions can be issued, allowing ships to plan safer routes, avoid high-risk zones and mitigate navigation risks. Further development of such risk early warning systems can help ships take proactive avoidance measures in advance. 1. Data Collection: Collect, organize and aggregate various feedback information through ship-borne satellite antenna terminals. The collected data includes ID, terminal number, time, longitude, latitude, ship speed, swing angular velocity and other related contents. 2. Data Calculation: Current ship stability coefficient = swing angular velocity / (ship speed^0.5 + 1); Stability coefficient of current recording point = swing angular velocity * (ship speed^0.5 + 1); Calculate the distance between recording points based on their longitude and latitude, filter the stability coefficients of recording points within a 10-kilometer radius of the current recording point, take all valid data within 1 hour from the current recording time, and compute their average to obtain the 1-hour stability coefficient of the current sea area. Similarly, calculate the average of valid data within 3 hours from the current recording time to get the 3-hour stability coefficient of the current sea area. 3. Data Analysis: The ship stability assessment result is categorized as "Dangerous" if the current ship stability coefficient exceeds 8, "Warning" if it ranges from 6.5 to 8, and "Stable" if it is less than 6.5. The sea area stability assessment result is categorized as "Dangerous" if the sum of the 1-hour and 3-hour stability coefficients of the current sea area exceeds 50, "Warning" if it ranges from 40 to 50, and "Stable" if it is less than 40. 4. Data Application: Timely detect the unstable state of ships to prevent accidents and ensure navigation safety; issue early warnings for possible severe weather and sea conditions, allowing ships to plan safer routes, avoid high-risk areas and reduce navigation risks.
