基于KEA128的电磁感应平衡车硬件电路

北京理工大学珠海学院2020届本科生毕业论文Hardware Circuit Design of Electromagnetic Induction BalanceCar System Based on KEA128AbstractThe two-wheeled self-balancing car has the characteristics of small size,fast steering,and can work in various environments.Many of its research results have been put into use intransportation,automated production and entertainment.With the rapid development ofcomputer technology and electronic technology,self-driving smart cars can independentlysense the current environment and quickly respond to acceleration,deceleration,steering andother operations,which has become a research hotspot in the field of automatic control.The "NXP"(formerly "Freescale")Smart Car Competition held by the Ministry ofEducation is a competition that focuses on current research hotspots in the field of automaticcontrol.It provides a platform for undergraduates to study and apply automatic controltechnology.Based on the eleventh "NXP"Smart Car Competition,this paper uses theS9KEAZ128AMLK microcontroller to design a two-wheeled self-balancing car system thatrecognizes roads through electromagnetic induction.In this paper,the force analysis model is first established to analyze the control principleof the balance car.Through the analysis of the demand of the system,the model of thesingle-chip microcontroller is selected.Furthermore,the overall task is decomposed,andvarious functions are implemented in a modular manner to complete each task finally.Finally,the mechanical structure is built and the modules are reasonably installed on thecar model,and the hardware circuit design and function implementation of the system arecompleted.Keywords:two-wheeled self-balancing vehicle;S9KEAZ128AMLK microcontroller;mechanical model
