Description of drawings
Fig. 1 is the structure chart of the utility model family multi-media device embodiments.
Embodiment
See also Fig. 1, be depicted as the structure chart of the utility model family multi-media device 10 1 execution modes.Family multi-media device 10 links to each other with video-audio playing device 11.In the present embodiment, family multi-media device 10 is a set-top box, and video-audio playing device 11 comprises TV 12 and sound equipment 14.In other embodiments, family multi-media device 10 can be other electronic equipment, as DVD player etc.
In the present embodiment, family multi-media device 10 comprises human detection circuit 100, signal amplification circuit 110, comparator 120 and processor 130.
In order to make the better effects if of pyroelectric infrared sensor 102, can detect the signal of human body more accurately, human detection circuit 100 also comprises interference filter element 104 and Fresnel Lenses 106.
Fresnel Lenses 106 is used for the infrared ray of human body radiation is focused on pyroelectric infrared sensor 102.In the present embodiment, Fresnel Lenses 102 is optical lenses of a kind of particular design that is made of plastics, it can focus on the infrared ray of human body radiation on the pyroelectric infrared sensor, thereby improves the sensitivity of pyroelectric infrared sensor 102, enlarges monitoring range.
The human infrared signal that signal amplification circuit 110 is used for being detected is amplified.In the present embodiment, because the human infrared signal that human detection circuit 100 is detected is very faint, thus adopt signal amplification circuit 110 that the human infrared signal that human detection circuit 100 is detected is amplified, in order to carrying out subsequent treatment.The physical circuit of signal amplification circuit 110 can adopt common signal amplification circuit, does not do at this and gives unnecessary details.
Human infrared signal and reference signal that comparator 120 is used for amplifying compare.In the present embodiment, comparator 120 compares human infrared signal and the reference signal that signal amplification circuit 110 amplifies, if the human infrared signal of amplifying is better than reference signal, then exports high potential 1, if the human infrared signal of amplifying is weaker than reference signal, then export electronegative potential 0.At this moment, comparator 120 has just quantized human infrared signal by relatively, and like this, processor just can be learnt the comparative result of comparator 120 according to the signal that comparator 120 is sent.In the present embodiment, reference signal preestablishes according to actual conditions, guarantees that comparator 120 can reflect correctly whether the user is using family multi-media device 10 to watch multimedia programming.
In the present embodiment, Preset Time can be set by the user according to real needs.Be made as 30 minutes as the user, so, the human infrared signal of judging amplification as if comparator 120 in 30 minutes is weaker than reference signal always, then illustrating did not have the user to use family multi-media device 10 to watch multimedia programming in these 30 minutes, at this moment, processor 130 just makes family multi-media device 10 be in power down mode automatically.Otherwise, the human infrared signal of judging amplification as if comparator 120 in 30 minutes is better than reference signal sometimes, then explanation also has the user to use family multi-media device 10 to watch multimedia programming, at this moment, processor 130 just can not changed the state of family multi-media device 10, keep the operating state of family multi-media device 10, restart next timing of 30 minutes simultaneously.
In other embodiments, for further control video-audio playing device 11, as, TV 12, sound equipment 13, family multi-media device 10 also comprise relay 140 and power interface 150.Relay 140 is connected between processor 130 and the power interface 150, is used under the control of processor 130 disconnecting or being connected of closed and power interface 150.Power interface 150 links to each other with relay 140, is used to video-audio playing device 11 power supplies.
When the human infrared signal that processor 130 amplifies is weaker than reference signal always, when promptly never the user uses family multi-media device 10 to watch multimedia programming, disconnect relay 140, to stop power supply to video-audio playing device 11 in the Preset Time section.At this moment, video-audio playing device 11 also just is in closed condition, thereby has further saved electric energy.
When processor 130 was in normal operating conditions at family's multimedia device 10, closing relay 140 was to continue the power supply to video-audio playing device 11.In the present embodiment, because when TV 12 is in normal operating conditions, if directly close its power supply, when powering on once more, it will directly enter operating state, is in normal operating conditions once more, processor 130 closing relays 140 so work as family's multimedia device 10, TV 12 also can be in normal operating conditions, and is synchronous with family multi-media device 10.
Family multi-media device 10 provided by the utility model can enter battery saving mode automatically when the user does not watch multimedia programming, and the continuous video-audio playing device 11 of close synchronously, thereby realizes the purpose of intelligent energy-saving.Simultaneously, family multi-media device 10 provided by the utility model has saved the power supply of loaded down with trivial details many family multi-media devices of remote controller operation, make the power management hommization and the intellectuality more of family multi-media device, meet the family multi-media device to the environmental protection and energy saving and the development trend of hommization day by day.
