The topic realize infrared ray remote control car which based on the single chip microcontroller whit intelligence automation. In this thesis, I firstly introduced the whole component of this system, then the hardware and software .In the part of hardware, I depicted the relation between the whole structure and modes, and further the inner structure and outer character of new programming chip. The intelligent automation control request is more and more high. The design uses MC-51 to do controls remotely the launcher and the receive processor. The automobile ahead and back use the direct current motor to control, while the step-by-stepping machine actuate the direct, The direct current motor uses the bridge type switching circuit to actuate the electrical machinery, Step-by-stepping machine actuates with the digital logic circuit. The wireless transmission controls the car running status. The two major part is composed by the hardware and the software, The hardware electric circuit realizations are take the single chip microcontroller AT89C51 as the cores, as master control electric circuit, Other periphery electric circuits are the subordinated electric circuit partial. The hardware electric circuit may divide into two modules, Transmission board module and receive board module. The transmission module may divide into three small modules: The motor-driven, the digital code demonstrated and the single chip microcontroller controls. The software partial design procedure is: Master program and interrupt entrance procedure program, initialization various variables program, keyboard work subroutine, severance receive procedure program, time delay subroutine and so on. This paper introduced on the above question in detail which is in the software and hardware design, the realization and the debugging process method, and adopts the corresponding step to solve the problem.
Key words：Infrared remote control; Receive yard; Send yard; The single chip microcontroller .
