Description

A kind of automatic mute remote control and remote control mute method based on mobile phone signal

Technical field

The present invention relates to remote control technical field, more particularly, to a kind of automatic mute remote control based on mobile phone signal Device and remote control mute method.

Background technology

The today popularized in set top box, see that TV has become one of most important recreation of broad masses of the people , and in the information age of today, mobile phone is also indispensable means of communication in people's life.The set top box commonly used at present Remote control is button infrared remote control.Now everybody when seeing TV programme, if run into when mobile phone has the phone to call in order to The call that television broadcast sounds are interfered with is prevented, the sound for turning off set top box or the volume for reducing it generally can be all gone manually. This is accomplished by user and goes to find set-top box remote controller, and most of user likes remote control to put everywhere, and user obtains to go everywhere Turn over the remote control of oneself.Find after remote control, press " Jing Yin " key on remote control or go gradually to eliminate with " volume-" button The sound of TV programme, then receives calls again.And many users do not know the position of remote control " Jing Yin " key, generally all use The sound that " volume-" button slowly eliminates set top box is answered the call again.It is time-consuming longer and pretty troublesome in this whole process, pursuing Efficiency and allegro today's society, such mode are obviously not intelligent enough, if Very Important Person phone because it is long when Between missed call and miss a deal and just lose greatly.

In existing set-top box remote controller, each function is all the key device using hand, when user needs to realize Eliminate television broadcast sounds when be all " Jing Yin " key directly pressed by user on remote control or gone with " volume-" button by Fade except the sound of TV programme.Existing remote control quietness technology is that user directly presses " Jing Yin " button on a remote control, One specific code value is produced by remote controller key and is transported to MCU, is sent after being encoded through MCU by infrared transmitting tube and gives set top box Decoded.

The content of the invention

In order to overcome the deficiencies in the prior art, present invention firstly provides a kind of automatic mute remote control based on mobile phone signal Device.

The present invention also proposes a kind of remote control mute method based on mobile phone signal.

Realize when user is seeing TV programme and when the mobile phone on side has phone to call in, set-top box remote controller is just automatic Send a mute signal and realize mute function to set top box, facilitate user to be conversed in order to avoid being done by television broadcast sounds Disturb.Go elimination Jing Yin when user thinks that mute function can be eliminated, then with remote control, continue normal appreciation TV programme.

To achieve these goals, the technical scheme is that:

A kind of automatic mute remote control based on mobile phone signal, including it is sequentially connected with antenna, mobile phone signal detection circuit, micro- Controller and infrared transmitting tube, also including remote control panel button, the input of the output termination microcontroller of remote control panel button.

Mobile phone under holding state is after the call signal that base station is sent is received, it will send answer signal, hand The antenna of machine also has of short duration radiofrequency signal and sent out.Above-mentioned antenna is mounted in a small size antenna on the pcb board of remote control and filled Put, antenna connection mobile phone signal detection circuit will send a high level when electric circuit inspection is to the radiofrequency signal for having mobile phone Signal is to the microcontroller of remote control, and MCU detected after this signal with the volume as " Jing Yin " button on remote control Code mode is encoded, and produces modulating wave by integrated circuit after coding, then launched by infrared diode.Set top box connects Receive after this signal, demodulate mute signal and realize quick set top box mute function.

Above-mentioned microcontroller is the brain of remote control, and microcontroller is during fabrication just by the various menu encrypted messages of set top box Wherein, the frequency that remote control is used typically 38KHz is encoded to different key in a certain way for storage.

In a kind of preferred scheme, the mobile phone signal detection circuit includes inductance L1, inductance L2, resistance R1, resistance R2, resistance R3, resistance R9- resistance R17, electric capacity C1, triode Q1-Q4;
