Abstract
Smart electric car is an integrated system that includes environmental awareness, planning decision-making, driving automatically and so on. It intensively uses the computer, sensing, information, communication, navigation, automatic control technology and artificial intelligence. It is a typical high-tech complex.
This design adopts AT89C51 single chip computer of MCS-51 series. The core of the control circuit of AT89C51 to SCM adopts the modular structure design.The different detection circuits are composed of photoelectric sensor, metal detection sensors, ultrasonic sensors and so on. In the track, the intelligence car can automatically track orbit、detect the metal plates embedded、evade obstacles、measure mileage and so on. Using photoelectric sensor automatically track, it can make the car to walk along the black line. Using ultrasonic sensors, it can detect obstacles on the road. It can use the metals detection sensors to detect metal and record time by the LCD1602. At last, the car smoothly stops through the final guidance of light source.
Keywords: AT89C51 single chip microcomputer; automatically track orbit; detect the metal plates; ultrasonic barrier measurement
