基于光电管的智能车模设计

The Design of Smart Car Model Based on Photoelectric Cell

智能车模循线方案很多采用CCD来实现,其优点是象素密集,控制精度高,但是该方式信号采集周期较长,很容易受到外界光线的干扰,为解决这些问题,笔者采用红外光电对管进行循线的方案,虽然采集到的信号离散点数较少,但抗光线干扰能力强,响应时间短,成本低,而且通过对光电对管布置方案的优化,能够实现满意的循线控制。本文结合我国首届飞思卡尔杯全国智能汽车大赛的车模设计,对智能车模循线控制系统的软硬件设计思路、控制算法、程序代码等进行了论述。

The smart car model is usually implemented by CCD, and has the superiority of dense pixels and high control precision. But the CCD uses much time to acquire and process signals, and easily interfered by outside light. Smart car automatic routing based on the infrared double photoelectric cell was presented for the the smart car model. Ahhough the infrared double photoelectric cell acquires much less discrete signals, it responses quickly and costs little and is good at anti-jamming aroused by light. The smart car model can route well with optimized arrangement of the double photoelectric cells. The thought of software and hardware design, the control algorithm, code, as so on, were analyzed for the control system of the smart car automatic routing.
