Abstract

The invention relates to an infrared signal transmitting method, an infrared signal transmitting device and a remote controller, belonging to the technical field of wireless transmission. The method comprises the following steps: generating a binary sequence corresponding to buttons when buttons are pressed for each button in a remote controller; decoding and modulating the binary sequence so as to obtain pulse train signals; and transmitting at least two pulse train signals in an infrared signal mode before the buttons are released. According to the method, the problems of weak anti-interference capability and low remote control success ratio of the remote controller in the technical scheme related to the prior art are solved; the possibility of receiving infrared signals completely is improved, and also the anti-interference capability and the remote control success ratio of the remote controller are improved.

Description

technical field [0001] The present disclosure relates to the technical field of wireless transmission, in particular to an infrared signal sending method, device and remote controller. Background technique [0002] In daily work and life, infrared remote control technology is usually used for wireless remote control of household equipment such as TV sets, air conditioners, refrigerators, and set-top boxes. The basic principle of infrared remote control technology is: the user operates the remote control to send out infrared signals, and the remote control equipment (TV, air conditioner, etc.) Corresponding components in the remote control device perform corresponding operations. [0003] The NEC protocol is a commonly used infrared transmission protocol, which specifies the transmission format of infrared signals. Please refer to figure 1 , figure 1 is a schematic diagram of an infrared signal exemplarily shown according to the NEC protocol. In the NEC protocol, a compl...
