摘 要
随着现代科技的不断进步，军事上对快速、精准的巡逻警戒车辆要求已经越来越高，这就催生了智能巡检车的迅速开展，关于智能小车的研究也就越来越受人关注，具有很好的开展前景。循迹打靶智能小车是一款能够按照随机设定的路线自主循迹，快速到达预定地点时能够准确停车，通过光敏传感器智能搜索靶标并进行精确打靶的智能小车。
循迹打靶智能小车的硬件设计主要包括核心控制板、信号检测、驱动电路三局部。通过红外光电对管采集赛道信息、判断停车位置,数字光电传感器和光敏三极管搜索靶标位置，将信号传入核心控制板后对驱动电路发出指令，由大功率MOSFET构成的全桥电机驱动电路为电机准确的执行四相象运行提供有力保障。从而使智能小车完成循迹、光电瞄准靶标、激光打靶功能。
智能小车不仅可以使警戒巡逻任务执行更加高效，防止敌对危险目标进入重要区域造成破坏，而且在抢险救灾和工业应用等方面也都有非常重要的应用，同时也为循迹和光靶搜索实现了一种检测可靠、价格适中的创新性传感器设计方案，为以后制作性能更加优良智能车提供了根底。在硬件系统设计中尝试了多种方案的综合应用，采用了科学的硬件设计思路，从而为更优秀的控制策略提供了可靠有效的传感器模块，使整个系统的稳定性、快速性、准确性到达较高的水平。

Abstract
With modern technology continues to progress, the military for fast, accurate patrol vehicle requirements have been increasing, which gave birth to the rapid development of intelligent patrol car, research on the smart car is more and more concern , with good prospects for development. Traction targeting smart car is a random set route in accordance with their own tracking, quick reaches a predetermined locations to accurately Parking, intelligent search through light sensors for accurate target shooting and smart car.
Targeting and tracking Smart car hardware design includes the core panel, signal detection, driver circuit three parts. Collected by infrared photoelectric tube track information to determine parking location, number of photoelectric sensors and phototransistor search target position, the signal after passing the core panel issued a directive to the drive circuit, constituted by the power MOSFET full-bridge motor drive circuit is motor accurate likeness perform four runs to provide effective protection. Making smart car complete tracking, optical targeting target, laser shooting functions.
Smart car can not only make the task more efficient security patro
