Abstract: With the development of science and technology, people's living standard continuously improving and the awareness of energy saving and environmental protection is gradually strengthening. Researchers continue to research and development of new products used in life so that we improve the quality of life-saving resources at the same time. Infrared remote control technology is born of. Infrared remote control technology has been in day-to-day household appliances has been widely used, and its easy-to-use, low power consumption, anti-interference ability of the advantages of increasing intelligence apparatus in the system be taken seriously. All kinds of household electrical appliances market infrared remote control system technology is mature, low-cost homes for people's lives more convenient and efficient service.
This paper describes the use of transformer, rectifier diodes, capacitors and three-terminal voltage regulator as a power circuit, using a new type of infrared transmitter and receiver chips BL9148 as a launch and receive NB9149 circuit, through the codec, the output signal, and transmit them to the control circuit to control the load circuit.
