摘要
针对小车在行驶过程中的寻迹要求,设计了以H8/3048F单片机为核心的控制电路,采用模块化的设计方案,运用8组高灵敏度的红外线光电对管,对路面白色进行检测。利用单片机产生的PWM信号控制系统的角度,速度,从而达到弯道行驶,直道行驶,变道行驶的目的。试验结果表面,该系统具有较好的检测与识别能力,具有速度响应快,稳态性好,抗干扰能力强等特点。
According to the model car＇s trace-keeping request during its travelling, a control circuit centered in H8/3048F SCM is designed.In this design,a modular scheme and eight highly sensitive infrared photomuhiplier tubes are applied so as to detect the white on the trace. With the PWM signals generated by the SCM,the angle and velocity of the system is controlled,and through this way,we achieve the purposes of the model car＇s curved travelling,direct travelling and direction-switched travelling （DST）. The result of the experiment signifies that the system has many merits such as good ability of detection and identification ,fast response speed, good steady state and strong disturbance resistance.
