基于 STC89C52 单片机的自动照明智能小车系统设计与实现 Design and implementation of automatic lighting intelligent car system based on STC89C52 摘要随着经济的发展，信息化和智能自动化越来越成为世界主流的发展趋势，也是各国科研机构和学术单位的研究方向。现如今也研究出了许多先进的智能机器人技术，其中智能小车作为智能机器人的其中一员，受到的人们的关注也越来越多。通常智能小车能过循迹功能寻找预先设定好的路线，并依照路线进行移动。本设计主要是关于智能小车的循迹功能的研究，在此基础上拓展其他功能，如主动避障功能、光线感知功能等。智能小车主要使用了 STC89C52 单片机作为主要控制元件，两个 L293D 电机驱动芯片控制的直流减速电机作为动力源，RPR220 反射型光电探测器作为避障模块传感器；主要功能表现为自律行驶时能够识别前方障碍物并转向规避障碍物、能够跟随黑色轨迹路线行驶、能够通过遥控器切换智能小车当前执行功能。通过这些功能达到智能小车“智能”的目的要求。关键词： 智能循迹小车 STC89C52 单片机 避障 遥控Abstract With the development of economy, information technology and intelligent automation have become more and more the mainstream of the world, and also the research direction of scientific research institutions and academic units in various countries. Nowadays, many advanced intelligent robot technologies have been developed. As one of the intelligent robots, the intelligent car has attracted more and more attention. Generally, the intelligent car can find a pre-set route through the tracking function and move according to the route. This design is mainly about the research of the tracking function of the intelligent car. On this basis, it expands other functions, such as active obstacle avoidance function, light perception function and so on. The intelligent car mainly uses STC89C52 as the main control element, two L293D motors drive the DC decelerating motor controlled by the chip as the power source, and rpr220 reflective p...
