摘 要 智能作为现代的新发明，是以后的发展方向，它可以按照预先设定的模式在一个环境里自动的运作，不需要人为的管理，可应用于科学勘探等等的用途。智能电动车就是其中的一个体现。智能遥控技术是指实现对被控目标的遥远控制，在工业控制、航空航天、家电领域应用广泛具有抗干扰能力强，信息传输可靠，功耗低，成本低，易实现等显著优点，电子设备特别是家用电器广泛采用，并越来越多的应用到计算机系统中。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 the computer 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 is completed 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 test of the car .Its function is equivalent to a simple robot. The speed of the car is controlled by PWM wave output under the microcontroller. The circuit of the whole system is simple structure and high reliability. The test results meet the requirements, this article focuses on the design of the hardware design and the process of debugging test results analysis. The technologies used in this design are infrared remote control technology; e
