Abstract
This graduation project based on monolithic integrated circuit's infrared remote control switch, the paper first introduced system's main assembly, then divides into the hardware and the software two parts carries on the elaboration. The hardware circuit part mainly described the infrared receive master control module with the various modules reciprocity, this part mainly uses MC-51 to do controls remotely the launcher and the receive processor. This system after actual use, proved that its convenient, reliable and has the use value. the topic involves to the hardware and the software two major parts, hardware circuit part realization is take monolithic integrated circuit AT89C2051 as a core, takes the master control electric circuit, other peripheral circuit to be subordinated the electric circuit part. May divide into two modules the hardware circuit, the control code module and the launch module, divides into again the remote control module three small modules: Monolithic integrated circuit master control, infrared receive module and power unit. The software part design procedure may divide into: Master routine and in interrupt routine entry program, initialization routine various variables, master routine, keyboard work subroutine, interrupt receive procedure, time delay subroutine and so on. This paper introduced in detail on the above question the software and hardware design, realizes the method which uses with the debugging process, and adopts the corresponding step to solve the problem.
key words: Infrared remote control; Receive yard; Send yard; The single chip microcontroller .
