Design And Implementation Of Helicopter Transportation Mission Planning System

As a flexible medium-low altitude flying platform,helicopters have been widely used in various industries.Helicopter transportation is an important form of its application.In order to ensure the implementation of the helicopter transport mission,a reasonable planning is required.However,the conditions and constraints that influence the process of the helicopter transport mission should be fully considered,including the natural environment and helicopter performance,which was mainly accomplished by manual means in traditional helicopter mission planning.Traditional helicopter transport task planning is mainly completed by manual means.On the one hand,it is inefficient and time-consuming,and on the other hand,the planning process involves many fields,which is a severe test to the operational level of command and dispatch personnel.Therefore,a task planning system for helicopter transportation,is urgently required to assist the command and dispatch personnel to work out the mission implementation plan scientifically and reasonably.This thesis considers with the requirement of helicopter transport task,sorts the operational characteristics of the three stages of helicopter transport,including loading,flying and landing.And in view of the present situation of the complicated process of helicopter transport task planning and the lack of information means,designs and implements the system flow,architecture and function module,develops a Task Planning System for helicopter transportation,which has the functions of 2 / 3-d interactive display,danger area simulation,planning,route planning and load distribution.The system mainly consists of front-end helicopter transport task planning software,backstage route planning service and passenger load distribution service.Based on the military information network system theory,the system architecture is composed of resource layer,service layer and application layer,which adopts service-oriented architecture technology and the idea of separation of service,control and load the background route planning and load distribution of the system are designed and implemented by using the micro-service framework.The forward helicopter transportation task planning software is based on the unified software framework.The system is implemented by means of "frame + function plug-in”.And the system solves the problem of automatic load distribution of helicopter by constructing a helicopter load model,according to the weight and relation of personnel,equipment and materials,this system adopts A* algorithm and combines the flying characteristics and performance of helicopters to avoid the dangerous area and solve the problem of automatic route planning.The functional modules of the Helicopter Transport Mission Planning System designed in this thesis have been applied to several projects with respect to national defense information systems,where the effectiveness of our modules has been demonstrated.In particular,the designed load distribution and landing site selection methods can well meet the actual needs.The related projects are significant in supporting the independent and joint missions of the helicopters.
