摘要
寻线轨迹技术是使移动物体识别地面上线轨迹,进行可控移动的技术,也是许多电子比赛中的题目。本文着重分析了2种寻线控制电路的结构和特性。一种是基于HS0038红外接收器的电路,特点是工作距离比较远,另一种是基于红外反射开关tcrt1000的电路,特点是工作较稳定,但是探测距离近。作者对后一种电路进行了实验与改进,提高了灵敏度,可以用于检测线与背景反差较小的情况。
Route finding technology is usually used to control the moving objects by detecting the route on the ground,which are also used in the themes of many electronic competitions.It emphasizes the structures and features of two route finding circuits.One is based on HS0038 infrared receiver working with long detective distance.The other is based on Tcrt1000 infrared reflective switch,which detects short distant route but has high stabilization.This paper has made improvement to the latter circuit;therefore,the circuit can be utilized to find the route on the ground where the contrast of the ground and the route is low.
