基于检测与转换技术的小车循迹系统设计

Design of Tram Track System Based on Detection and Conversion Technology

本文提出一种轨迹传感器,包括反射式光电采样器、信号缓冲、背景光消除电路等等,将处理后的红外光反射强弱模拟信号送入单片机,由单片机的A/D转换为数字信号后,再由软件来判断是否在轨迹上。

In this paper, a kind of trajectory sensor, including reflector photodetector, signal buffer, background light elimination circuit, etc., is proposed to send the simulated signal of infrared light reflection strength and strength to the single chip computer, and convert the A/D of the single chip computer into a digital signal. It ＇ s up to the software to determine if it ＇ s on track.
