The Design Of The Intelligent Toy Car Based On Single Chip Microcomputer

Now, toy electric cars can only be achieved either straight forward or open loop control with a remote control device, can be realized, or forward or backward, or to the left, or right function. Can display operating status, mileage(number of turns) and an alarm but a few.The main work of this article is to design and implement an electric vehicle based on microcontroller STC89C51 smart toys, including its hardware and software parts. Hardware circuit section includes a controller, signal detection circuit, obstacle avoidance circuit, motor drive circuit, display circuit, power circuit, realized through software programming control the car forward, backward, acceleration, deceleration, turn left, turn right and lights flashing other functions, and in the car to achieve a good marching obstacle avoidance, distance, direction of travel display and alarm.This thesis is the current general toy electric cars as a basis, increase the variety of sensors, such as photoelectric sensors, infrared sensors, ultrasonic sensors, using the sensor signal detection circuit composed of real-time detection of electric cars running speed, running position, operating conditions, SCM receives and processes the signal detection circuit detects a variety of data, and then issue commands to control the electric car is run by the microcontroller. The intelligent toy car can achieve the functions are: real-time and accurate display of temperature, showing mileage, enables voice control, automatic tracking and obstacle avoidance, can automatically adjust the travel speed and precision parking.
