Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0026] The remote control is a device used for remote control of machinery, which is mainly composed of MCU, antenna, mobile phone signal detection circuit, buttons, infrared emission tube and so on. The MCU in the remote control is the brain of the remote control. The MCU enters various menu password information of the set-top box into it when it is manufactured. The frequency used by the remote control is usually 38KHZ. The modulated wave is generated, and then emitted by the infrared emitting tube, and the set-top box decodes it after receiving it, and then executes the corresponding action.
[0027] The hardware principle block diagram of the present invention is as figure 1 As shown, it includes sequentially connecting the antenna, the mobile phone signal detection circuit, the microcontroller ...

The invention discloses an automatic mute remote controller and a remote controller mute method based on mobile phone signals. The automatic mute remote controller includes sequentially connecting an antenna, a mobile phone signal detection circuit, a microcontroller and an infrared emission tube, and also includes remote control board buttons, The output terminal of the remote control panel button is connected to the input terminal of the microcontroller. The antenna is a small antenna device installed on the PCB board of the remote control. The antenna is connected to the mobile phone signal detection circuit. When the circuit detects the radio frequency signal of the mobile phone, it will send a high-level signal to the microcontroller of the remote control. After the detector detects this signal, it uses the same encoding method as the "mute" button on the remote control to encode. After encoding, the modulated wave is generated by the integrated circuit, and then emitted by the infrared diode. After the set-top box receives the signal, it demodulates the mute signal to realize the fast mute function of the set-top box.
Description
technical field [0001] The present invention relates to the technical field of remote controllers, and more specifically, to an automatic mute remote controller and a remote controller mute method based on mobile phone signals. Background technique [0002] Today, with the popularity of set-top boxes, watching TV has become one of the most important entertainment activities for the masses, and in today's information age, mobile phones are also an indispensable communication tool in people's lives. The currently commonly used set-top box remote control is a push-button infrared remote control. Now when everyone is watching TV programs, if there is a call coming in from the mobile phone, in order to prevent the TV program sound from interfering with the call, they usually manually turn off the sound of the set-top box or reduce its volume. This requires the user to find the remote control of the set-top box, and most users like to put the remote control everywhere, and the us...
