自动循迹避障寻光智能小车软件系统设计

Software Design of Smart Car for Automatic Tracking Obstacle Avoidance and Light-seeking

在以单片机控制为核心,实现自动循迹、避障和寻光为主要功能的智能小车的硬件框架确定后,对实现功能配套的软件系统进行开发设计。用模块化嵌入式设计方法,采用C语言为编程语言,以STC89C52单片机为控制中心执行整个系统的运作,单片机根据各传感器模块反馈的信号来控制L293D电机驱动模块实现小车前进、后退、转向等运动。在搭建的小车实验平台上嵌入软件系统,对小车的功能实现、运动控制实际效果和小车运行的稳定性进行测试和分析,测试结果达到了预期的设计目的。

The hardware scheme of a smart car had first been determined. Its main functions were to realize pathway tracking,obstacle avoiding and light seeking with the control of single chip as its core. The software system was then developed and designed in this paper. The design of multifunctional car proposed modular design and analyzed feasibility of different design plans to achieve the car’s functions preferably. The system took STC89C52 as its core and adopted C as the programming language. Using the signals from different sensors, the single chip could control the car’s movement, such as advance, retreat and veer. In the last, the car’s experimental platform was set up. It was used to observe and analyse the car’s implementations of the functions, real effect of motion control and the operation stability. The test results showed that the desired purpose of the designed car was achieved.
