Method for forecasting maritime search and rescue region

Abstract

The invention relates to a method for forecasting a maritime search and rescue region, which comprises the following steps: inputting the accident occurrence position, the occurrence time, the forecasting time, the search and rescue object type and the sample quantity; utilizing the existing model to determine the wind pressure characteristic parameters of an object according to the search and rescue object type; generating an initial position sample set of the search and rescue object according to the accident occurrence position and the occurrence time; performing an experiment aiming at each sample in the sample set to obtain a final drifting position sample set; and calculating the probability of each region including a search and rescue target according to the final drifting positionsample set. The method has the advantages that the environmental factors are more carefully considered, the calculation basis is reliable, the calculation results are accurate, and the accuracy is high; and the method can effectively reduce the search and rescue region, improve the search and rescue efficiency, set any time and calculate the drifting position of the search and rescue object, and has good real time.

Description

technical field [0001] The invention relates to a sea search and rescue technology, in particular to a method for predicting a sea search and rescue area. Background technique [0002] Maritime search and rescue technology is widely used in the fields of maritime accident target position estimation, target search and rescue, and shipwreck rescue. The search and rescue area of ​​the maritime search and rescue target is usually determined by manual operation and paper work. According to the time difference between the search and rescue target and the initial position of the incident and the time to the current time, and referring to the environmental information of the current sea area, the possible location area of ​​the search and rescue target is roughly calculated. This method The reference to environmental information is inaccurate, and the search and rescue area formed is wide. It cannot effectively and accurately update the target search and rescue area dynamically acco...

The search and rescue area of ​​the maritime search and rescue target is usually determined by manual operation and paper work. According to the time difference between the search and rescue target and the initial position of the incident and the time to the current time, and referring to the environmental information of the current sea area, the possible location area of ​​the search and rescue target is roughly calculated. This method The reference to environmental information is inaccurate, and the search and rescue area formed is wide. It cannot effectively and accurately update the target search and rescue area dynamically according to the passage of search and rescue time, which affects the search and rescue personnel's judgment on the drifting process of the search and rescue target, and cannot accurately and effectively help search and rescue personnel to narrow down the area. In the search and rescue area, formulate a search and rescue plan reasonably and efficiently, thereby reducing the probability of successful search and rescue
