摘要
设计并实现了一种基于MC68HC908QY4单片机的自主避障智能模型车系统。本系统采用Freescale公司的MC68HC908QY4单片机作为核心控制单元,使用红外传感器采集路况信息,并通过一定的转换电路将传感器采集的模拟信息转换成单片机能够识别的数字信号,以便于单片机分析处理。通过单片机对红外传感器检测信息的分析、判断,从而给出判断结果,并给相应端口数字信号,再经过相应驱动电路驱动相应传感器,以达到自动控制转向,改变行驶路径,绕过障碍物的目的,从而实现自主避障智能模型车的稳定避障。
Design and implementation of a model is based on single-chip MC68HC908QY4 vehicle systems. The system uses Freescale＇s single-chip for the core control unit, the use of infrared sensors is collecting road information, and through the conversion circuit change into a single-chip, it can be able to identify the digital signal and it＇s easy for single-chip to analyse. Through the single-chip detection of infrared sensor information analysis and judgments, and thus giving the results to determine and give the corresponding port digital signal, and then through a corresponding drive circuit drives the corresponding sensors, to achieve automatic turning, steer clear of the obstacle. In order to achieve the stability of avoiding obstacle.
