Research On Automatic Route Design Based On AIS Database

With the continuous development of the shipping industry,ships increasingly tend to large-scale,intelligent,while people on the efficiency of maritime transport also put forward high requirements.Not only to ensure the high speed of transport,but also to meet the minimum transport costs.This is a great challenge to the researchers who are committed to the shipping industry.In today's times,technology development is changing with each passing day.The field of technology gradually mature,which makes our research is no longer based on the traditional pure theory,more is the application field.Automatic design of routes will gradually take a new step.This paper presents a method of automatic route design based on ship AIS data analysis,which provides a new research idea for route intelligent design.Route matching and screening is one of the core parts of the route design,plays a pivotal role.In order to complete the route matching and screening purposes,in the form of EXCEL form,a certain number of ship AIS data are selected and stored in the designated sea area as the database of route matching and screening.The visualization program VB is used as the technology platform of route matching and screening,and the main content is programmed by matching principle and screening condition.Among them,the matching process,the matching parameters of the priority level division.Under the conditions of satisfying the highest priority parameters,the matching results are classified according to the number of other parameters.Matching results and matching levels will eventually be presented in visualization results to facilitate subsequent screening of target routes.Route screening is based on certain comparative conditions.In this paper,the range of the voyage is used as a reference,and the operator can be screened by calculating the voyage of each trajectory.For a number of qualified traces,to be manually intervened,the operator according to the actual situation to select the appropriate results.Finally,the target route is displayed on the electronic chart by means of manual input.In this paper,the combination of theory and practice is realized through practical operation,and the experimental results meet the preconditions.Then,the whole experiment process is analyzed and the idea of improvement is put forward.It is of great significance to promote the automatic design of route.
