Abstract
This paper is a single-chip light, acoustic signal processing in order to achieve tracing the car intelligent system design, including system is divided into several modules to achieve.
System in accordance with the division of functions as follows: path identification module (through an external infrared sensor incoming signal), the DC motor driver module (by the ultrasonic sensor incoming signal), steering gear steering module, the speed measurement modules, power modules, microcontroll ercontrol system module, to run the debug module, and and so on on. Received feedback signal from the microcontroller calculated issued a directive to adjust the run.
Finally, the STC-ISP software program written to microcontroller, testing, debugging, to achieve the expected results of the experiment. Experiment is expected to reach the results that the car can be along the designated black line tracking forward and effectively unblinded.
key words：Tracking; smart unblinded; microcontroller; infrared, ultrasonic detectors
