Abstract:

This article particularly introduces a design method of the hardware system for an intelligent-searching track car based on infrared laser diode.The system uses MC9S12XS128 as the control core,employs infrared laser diodes and infrared receiving sensors to acquire path information,adopts the internal integrated H-bridge circuit MC33886 chip to realize motor drive,and uses a LM331 chip to design the speed measuring circuit.In order to achieve the automatic tracking function,this system can analyze and process the data of the collected path and the feedback of speed,promptly steer the servo,and adjust the motor speed.
