For a moving car in the process of tracing requirements, designed to AT89C51 single-chip microcomputer as the core of the control circuit, the use of modular design, using color code sensor, metal detector sensors, ultrasonic sensors, Hall sensors composed of different detection circuit to realize a moving car in the track, detect embedded metal iron, avoid obstacles, issues such as measurement of the speed detection circuit and the design of a theoretical analysis and practical test. The results showed that the Smart car has a good ability to identify and detect, with positioning accuracy, the characteristics of stable and reliable operation.
