Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of home appliance remote control, and in particular relates to an infrared remote control method and device. Background technique [0002] With the improvement of people's material and cultural living standards, various household appliances have entered thousands of households, and most household appliances are controlled by infrared remote controllers. [0003] The infrared remote controller is composed of an infrared transmitting circuit, a signal modulating circuit, a central controller and a data memory, a keyboard and a state indicating circuit. When the user presses a button, the controller will read the key value information of the button pressed by the user, and the controller will obtain the infrared code value corresponding to the key value of the button from the designated storage unit, and after the code value signal is amplified, it will be transmitted by the infrared ray The emitting diode emi...
