Infrared remote control method and device

The invention provides an infrared remote control method and device. When infrared remote control equipment provided by the invention is used for remotely controlling controlled equipment, firstly, at least one testing signal of emission intensity is sequentially sent to the controlled equipment, and the current lowest emission intensity capable of being received by the controlled equipment is determined according to a testing feedback signal returned back by the controlled equipment; then, a remote control signal is sent to the controlled equipment according to the lowest emission intensity capable of being received by the controlled equipment so that the emission intensity can be increased when the infrared remote control equipment has low electric quantity or is in a long distance, and the emission intensity can be reduced when the infrared remote control equipment has high electric quantity or is in a short distance; and the effective control on the controlled equipment by an infrared remote controller is guaranteed, and the service time of a battery in the infrared remote controller is prolonged, so that energy sources are saved.
