Abstract

The invention relates to a method for the infrared remote control of a computer, which is applied to an infrared remote control system of the computer. The infrared remote control system of the computer consists of an infrared signal sending terminal, an infrared signal receiving terminal and the computer. The method comprises the following steps of: S1, performing initialization; S2, scanning a keyboard; S3, sending an infrared remote control signal with a complete code; and S4, judging whether an infrared remote control signal with a duplication code is sent or not. The method has the advantages that: by extending the encoding bits of an address code and a data code of the complete code of the infrared remote control signal and extending the encoding bits to 12bit from 8bit, the data capacity of the infrared remote control signal is increased by 16 times, the conflicts and the mutual interferences between the address codes of different remote control devices are avoided, and simultaneously, the increase of the data code adapts to complex operational processes of the computer, so the integration of the operations of household electrical appliances and the computer is implemented.

Description

technical field [0001] The invention belongs to the technical field of infrared remote control, in particular to an infrared remote control method suitable for computer infrared remote control. Background technique [0002] At present, the technologies for short-distance wireless transmission or control between devices mainly include Bluetooth, WAPI, Wi-Fi, NFC, Zigbee, Wireless USB, Wireless 1394, and IrDA. The most economical way is IrDA infrared transmission and control. Infrared technology uses near-infrared rays with a wavelength between 0.76 μm and 1.5 μm to transmit control signals. The infrared communication process mainly includes two processes: infrared emission and infrared reception. The signal sent by infrared needs to be modulated to reduce the error probability, and the carrier frequency is between 30kHZ-60kHZ. Commonly used infrared coding methods include NEC, Philips, Sony, Sharp, Panasonic, Nokia, etc. The technologies based on different protocols are mai...
