R&D And Application Of Positioning And Queue Transformation Technology For Multi-smart Vehicles

In order to improve the situation that the technology used in the entertainment equipment in the market is relatively backward and cannot meet consumer's demand,this paper combines wireless sensor network technology,embedded technology and UWB positioning technology to apply to the smart car,and designs a multi smart cars control system.This paper analyzes the functional requirements of the multi smart cars system,analyzes the control scheme required to fulfill the functional requirements,and gives the overall framework of the multi smart cars system.CC2530 chip with Zigbee protocol is selected as the main control chip of the smart car to realize the information exchange between smart cars,using UWB technology to realize the positioning of smart cars,and STM32F407 is selected as the main control chip of the overall control unit of the system.The excellent performance of the STM32F407 chip enables it to complete the task of this design.In this paper,according to the overall framework and the selection of main control chip to determine the selection of other chips and modules in the system,the hardware design of each module,the software design of each function.This paper analyzes the positioning algorithm based on UWB,and proposes a solution to realize multi smart cars positioning.The raster method and artificial potential field method are analyzed respectively,and the algorithm design for formation control of multi smart cars are given by combining the two methods.The prototype of the multi smart cars system is completed,and each module and function in the system are debugged and improved.The operation of the multi smart cars system is stable and the function is normal,which meets the requirements of this design.
