基于32位MCU的视觉导引自平衡车控制系统硬件设计+电路图

摘要本文以“飞思卡尔”杯全国大学生智能汽车竞赛为背景，根据比赛规则，提出了基于32位MCU的视觉引导自平衡车控制系统的硬件设计方案。为了能让小车跟踪黑白路径文持直立行走，对车模机械系统和硬件系统进行了设计。在硬件电路中，首先选用FREESCALE公司的32位MK60DN512ZVLQ10作为核心控制芯片。硬件电路设计采用模块化的思想，整个硬件电路包括MCU模块、电源管理模块、赛道采集模块、姿态检测模块，电机驱动模块、速度测量模块、人机接口模块、SD卡模块，蓝牙通信模块等。然后根据对汽车机械结构的学习，对比赛指定车模进行合理机械改造，并且设计硬件原理图并且制作了全部PCB板。最后进行系统分模块调试和系统联调。最终测试结果表明，系统稳定，基本满足所有设计要求。22885

Title Design and Realization of Intelligent Vehicle for the   Ninth Freescale Cup —— Hardware Design of the Visual Guidance Guidance Intelligent Vehicle Control System based on 32-bit MCU
Abstract
This passage is based on the ninth Freescale Cup National University intelligent car contest. According to the contest rules, the hardware design of intelligent vehicle control system based on visual guidance has been proposed, and therefore the mechanical structure has been adjusted in order to make intelligent vehicle walk upright on the black and white path. The intelligent car utilizes the control core chip named MK60DN512ZVLQ10 which is produced by Freescale. After a specific analysis of the hardware, the whole hardware designing process was pided into several modules which include MCU module, power management module, visual sensor module, motor drive module, the speed detection module, SD card and bluetooth communication module. Based on the study about mechanical structure of vehicle, some proper adjustments were completed to ensure the performance and reliability of the car, and after that,the hardware circuit and PCB board were designed. Finally，the functional modules are tested as well as the whole system. The result shows that the hardware system has terrific performance and meets the design requirements．
