A Design And Implementation Of Drifting Object Trajectory Prediction And Joint Rescue System

Behind the prosperity of maritime transportation,it is the frequent occurrence of accidents.Since searching drifting objects and the drowning person on the sea is an extremely difficult task,the costs and the expected results are seriously disproportionate and unpredictable.With the development of internet technology,the popularity of big data technologies and the widely used information technology systems-AIS,there is a great practical value of the research about how to use predicted rafting track of drifting object with the internet technology to conduct a united joint search and rescue of drifting object on the sea.This paper is to establish a comprehensive set of maritime search and rescue platform,which covers the entire process of handling dangerous situations on the sea.This paper studies the relevant models and techniques of predicting rafting track of drifting object on the sea.It has designed and established a set of joint search and rescue system,including the following:(1)The system calculates the designated position's meteorological data using interpolation method.(2)The system analyzes and calculates the Coriolis force that drifting object suffered.(3)The system analyzes the leeway model and calculates the CWL and DWL.(4)The system analyzes the force which the drifting object is suffering,and predict the trajectory.(5)The system calculates the searching radius according to total probable error and then finds out the optimal searching region.(6)1 studied the visual search mode and determine the way of implementation of each search with the required parameters.(7)1 designed and developed service interfaces and client softwares for Mysql and Hypertable databases.
