The invention provides an infrared remote control device for an intelligent host. An earphone interface of the intelligent host comprises a left channel output end and a right channel output end; the infrared remote control device comprises a modulation / demodulation module and an infrared transmitting / receiving module, wherein the modulation / demodulation module is used for modulating and demodulating control signals transmitted by the intelligent host and signal formats transmitted by the infrared transmitting / receiving module; and the infrared transmitting / receiving module is used for transmitting / receiving the control signals. The invention also provides an infrared remote control method for the intelligent host. The infrared control signals are transmitted through the earphone interface supported by intelligent mobile terminals, so that external electrical appliances are controlled; electrical energy can be provided for the device for transmitting the infrared control signals by acquiring the energy of the audio signals transmitted by the earphone interface; and by receiving the infrared control signals of the external electrical appliances, transmitting the infrared control signals to the intelligent host through a microphone input end and storing the infrared control signals in the intelligent host, the device has an infrared remote control signal learning function.
Description
technical field [0001] The invention relates to the technical field of information transmission, in particular to an infrared remote control device and method for an intelligent host. Background technique [0002] With the improvement of people's living standards, there are more and more household appliances and consumer electronic devices. Most of the household appliances have their own different remote controls. Using electrical appliances brings a lot of inconvenience. [0003] In addition, with the development of mobile phone and tablet computer technology, more and more people use these smart mobile terminals. These smart mobile terminals are equipped with earphone jacks, but the earphone jacks of these smart mobile terminals can only input and output audio signals through the left channel output terminal, right channel output terminal, and microphone input terminal. Output control commands. [0004] Since the earphone interface of the smart host has the advantages o...
