摘要:大学生竞赛车模系统的优化设计是基于“飞思卡尔”杯全国大学生智能汽车竞赛,对光电头循迹的自动行驶小车系统的机械结构、电子电路、程序设计、传感方案、图像识别和自动控制方面进行优化设计,并得到尽可能高效和稳定的设计方案。24150 智能车竞赛分为光电组、电磁组和摄像头组。路径识别模块是智能车系统的关键模块之一,路径识别方案的好坏,直接关系到最终性能的优劣,因此确定路径识别模块的类型是决定智能车总体方案的关键。在光电组中,以光电传感器进行赛道的检测是非接触式测量,其测量电路构成形式多样。本次课题设计旨搜集智能车赛事中的光电传感器电路,在对典型的光电传感器电路进行设计,对电路的性能进行比较与分析的基础上,提出优化的方案,并且讨论了光电传感器排列方法、布局、间隔等对寻迹结果的影响。路径识别模块是智能车系统的关键模块之一,路径识别方案的好坏,直接关系到最终性能的优劣,因此确定路径识别模块的类型是决定智能车总体方案的关键。 毕业论文关键词: 光电传感器; 智能车;性能比较;布局 The path of the college students competition models optimization Abstract: College students competition models optimization design of the system is based on "freescale" cup national smart car competition for college students, light DianTou automatic tracking of driving the car system of mechanical structure, electronic circuit, programming, sensing automatic control scheme, image recognition and optimization design, and get the efficient and stable design scheme as soon as possible. The intelligent vehicles competition is pided into the photoelectric group, electromagnetic Group and camera group. Path identification module is one of the key modules of the intelligent vehicles, path identification programs directly related to the final performance,so determine the type of path identification module is a key to determining the intelligent vehicles overall program.Detecting the track by photoelectric sensor is non-contact measurement. The measurement circuit have many forms. The subject is designed to collect photoelectric sensor circuit in the national college students’intelligent vehicles competition,and appropriately design some photoelectric sensor circuits, comparison and analysis of the performance of the circuits,make some the optimized programs.The effect s of sensor s’ array , overall arrangement , and space on t he autonomous t race are discussed. Keywords: photoelectric sensor;intelligent vehicle;overall arrangement ; comparison of the performance 目录 摘要 i Abstract i 目录 iii 1 绪论 1 1.1 课题的目的和意义 1 1.2 发展概况 1 1.2.1 国内背景 1 1.2.2 国外背景 2 1.3 研究的基本内容与拟解决的主要问题 3 2 光电传感器寻迹原理 5 2.1 传感器模块的描述及其原理 5 2.2 传感器电路的种类 7 2.2.1 红外对管传感器电路 7 2.2.2 激光传感器电路 7 3 智能车硬件设计 9 3.1 主控板设计 9 3.1.1 电源管理模块 9 3.1.2 电机驱动模块 10 3.1.3 中央控制电路 14 3.1.4 人机界面 15 4 软件设计方案 17 4.1 传感器的驱动以及信号采集 17 4.2 赛道信息的识别 18 (责任编辑:qin) |
