The Research And Implementation Of Truck Fleet Navigation System

Truck drivers usually perform the transport task in the form of a team. In order tomaintain formation, the drivers usually communicate with each other by mobile phonesor interphone. This way need drivers often make a phone call. It’s not intuitive, reliableand safe. This thesis force on the research and implementation of truck fleet navigationsystem(TFNS). This thesis put forward the concept of avoid-rally dynamicformation(ARDF). The implementation of TFNS provides a great convenience for thedrivers.Truck Fleet navigation mechanism study is to determine the team detailedformation mechanism, establish dynamic formation mode. First, by the team of eachobject in the system to establish the team navigation system functional division,information sharing mode between studies to determine the team. Then the head of thetruck fleet to the server push the route of the detailed content and cycle. Finally withtruck request done right through to the server the route of perception. To complete theentire team working mechanism, provide the basis for the dynamic formation.In the embedded devices calculation ability is not strong, dynamic route planningmethods needed for the formation. Of point-to-point A*algorithm is inspired by thecost optimization, make it suitable for point-to-line route plan problem. Thecharacteristics of adjacent time optimal path analysis, based on the history of the bestpath, critical bifurcation and dynamic destination fast heavy planning method, canquickly meet the demand of car following updates on the optimal path.Finally, we have a research about guide info that suitable for the truck fleet.Quadtree model to design dynamic depth map display elements to establish a spatialindex, and designed for use in navigation team team prompt information. Intersectioncan be divided into functional cross, voice induction information generated withnon-functional intersection respectively, intersection of speech.
