Abstract
The intelligent is a direction of developing in the future that as a new modern invent. It can follow the automatic operation in an environment with the pre-set pattern, management without anybody; also can be applied to the use of scientific expiration. Intelligent car is one reflect of its features. Intelligent remote control technology means charged with the target remote control, it widely used in industrial control, aerospace, home appliances field. However the infrared remote control is also a wireless, non-contact control technology, but it has a strong anti-interference ability, reliable information transmission, low power consumption, cheaper easy to implement and other significant advantages. So it widely used in many electronic devices which especially household appliances and more and more applications used into puter system. This design is based on the infrared remote technology design issues. This system is designed with its topics purpose that uses STC90C516RD+ MCU as the core to control the car that with the using of infrared remote control to control the running direction and speed. The driver of the car pleted by the L298N driver module, because the L298N chip has a high excellent performance so the speed of the motor is stability. The motor used a DC motor which is easy to control. We found the car can detect a variety of different track line running stability; strong practicality by the te
