Learning infrared remote control
[Abstract]Infrared remote control technology on the market at present many application fields has been widely used.Infrared remote control technology has been widely applied in the field of intelligent household appliances and industrial control.This system design USES embedded master control chip to design the universal learning infrared remote control, USES the ARM architecture (M3 STM32 series chip as the core part of the kernel, combined with infrared emission and receiving module circuit, signal modulation circuit, keyboard constitute the system independently.From two aspects of the emission and receiving of infrared in detail introduces the principle of infrared wireless transmission, infrared signal code parsing, modulation, signal transmitting and receiving, signal demodulation and decoding principle.This system realize the different encoding (PWM \ parts per million (PPM) of infrared signal capture, decoding, regeneration of the infrared signal, the carrier and send the infrared signal, realize self learning infrared remote control.The realization of the function of this system needed to apply to a variety of electronic products research and development technology, which mainly contains the C language programming in a high-level language technology, single-chip computer application technology and electronic circuit board design techniques and related electronic application technology.Integrated a variety of design considerations and the various aspects of factors, finally decided to adopt high performance, low cost, low power consumption of the ARM architecture , realize to capture and various kinds of infrared remote control signal regeneration, truly universal learning infrared remote control.
