Design And Research Of Water Rescue System For Autonomous Cruise UAV

Areas in our country,the vast,the waters area is the third largest in the world,with the rapid development of water transportation,emergency search and rescue,and regulation for the water pressure increasing,drowning victims each year in China is not a few,how accurate relief against the water in a short time has always been the hot spot of the research problem,unmanned aerial vehicle(uav)as an efficient and convenient tool,Compared with traditional way,with the need to consider the advantages of the airborne life,ups and downs preparing time is short,can in a relatively short period of time and extreme weather environment for effective search and rescue,can greatly improve the efficiency of rescue,however,our country related water rescue history is shorter,foundation,at present is still in the exploratory stage and lack of the corresponding core technology such as path planning.In view of this article in view of the unmanned aerial vehicle(uav)water rescue problems,based on six uav rotorcraft unmanned aerial vehicle(uav)design a set of practical water rescue system,the system through the accurate positioning,GPS positioning module implements the rescue site at the same time an hd camera and transmission system,can realize long-distance monitor,to help the rescue workers to better observe the environment to carry out the rescue work.In addition,the uav is equipped with a self-developed life-buoy delivery system below,which can carry three life-buoy,which can be operated and controlled through mobile APP to complete three effective delivery of life-buoy.The rescue situation and carrying status of life-buoy are transmitted back to the operation interface through GSM module,improving the success rate and efficiency of rescue.At the same time,the autonomous cruise path planning problem in UAV rescue search is studied,and an efficient uav path planning algorithm is proposed to search concave and convex polygon area,which can achieve no missing coverage of the search area in a short time.First,in view of the concave and convex of search and rescue region is different,in the existing regional processing algorithm gives a treatment scheme of concave and convex polygon area respectively,and how to further divided area algorithm flow,and proposes a concave polygon convex decomposition algorithm based on shape optimal,to reduce the complexity of the search area uavs,reduces the difficulty of the task,unmanned aerial vehicle(uav)search Second,unmanned aerial vehicle(uav)is given based on the minimum redundant paths subdomain traversal sequence,the uav can accomplish the mission in a relatively short time,at the same time for missing areas and unmanned aerial vehicle(uav)to study the way of turning,to update a uav path optimization,implementation uavs exhaustive search coverage,process and gives the specific algorithm,based on the simulation analysis,The correctness and effectiveness of the algorithm are proved.Finally,the code design and implementation of uav autonomous cruise mission is carried out,and the algorithm proposed is integrated into uav autonomous flight mission,and the code task flow of UAV autonomous cruise is described.
