ABSTRACT
Infrared remote control is widely used in household appliances and instruments, because of infrared devices with small size, low power consumption, functionality and low cost series of advantages, which in TV, audio equipment, air conditioning and other electrical devices and toys are also have used infrared system. In the industrial field, using infrared equipment to transmit a very wide range of infrared remote control is not only safe, reliable and no electrical interference. Introduced Silan 6122 infrared remote control chips are used in the understanding of the emission pulse waveform coding, the design of AT89C52 microcontroller based infrared remote control decoder implements a use of MCS-51 Microcontroller external interrupt infrared remote control receiver, focusing on the infrared remote control decoding process realization, and the pattern is analyzed to determine the decoding process to achieve the model, and that the process flowchart design process, design a simple to use keil c51 infrared receiver program . After decoding the signal by the microcontroller through P0 oral delivery LCD screen display.
