Remote control method for reflecting infrared light through reflection remote control handle

Abstract

The invention discloses a remote control method for reflecting infrared light through a reflection remote control handle. The remote control method comprises the following steps: 1, an infrared emitter emits infrared light, the reflector of the reflection remote control handle reflects infrared light on the reflector, and an infrared camera receives the reflected infrared light, forms an infrared image identification point and transmits to a controller; 2, a shielding sheet shields the middle portion of the reflector, two reflection areas are formed at two sides of the shielding sheet, and the infrared camera receives infrared light reflected by the two reflection areas, forms two infrared image identification points and transmits to the controller; 3, a first control signal is sent when the number of the infrared image identification point received by the controller becomes 2 from 1, and a host responses the first control signal; 4, the shielding sheet is removed, a second control signal is sent when the number of the infrared image identification point received by the controller becomes 1 from 2, and the host responses the second control signal; and 5, steps 1-4 are repeated. The remote control method can realize the remote control operation of the host without a button, and has the advantages of simple and convenient operation, accurate remote control, and prolongation of the service life of the reflection remote control handle.

Description

technical field [0001] The invention relates to the technical field of infrared remote control, in particular to a remote control method for reflecting infrared light through a reflective remote control handle. Background technique [0002] With the continuous progress and development of science and technology, there are more and more electrical appliances in daily life, and there are also various remote control methods for these electrical appliances, and various remote control methods are becoming more and more convenient. It's more convenient to get up. [0003] Among the various remote control methods, the remote control of electrical appliances by reflecting infrared light through the reflective remote control handle is more and more widely used because of its simple operation, fast and accurate response. The existing method of remote control of electrical appliances by reflecting infrared light through the reflective remote control handle is mainly to emit infrared li...
