Embodiment
See also Fig. 2; Fig. 2 is the sketch map of audio-video system 2 of the present invention.Audio-video system 2 comprises tuner 11, Sound Processor Unit 13, television decoder 15, master control integrated circuit 24, power control circuit 22, power supply unit 20, battery 26, first switch (SW1) 27 and second switch (SW2) 29.
Master control integrated circuit 24 comprises between first circuit 241 and second circuit 242, the first circuit 241 and the second circuit 242 has coffret, and first switch 27 and second switch 29 are by 242 controls of second circuit.Wherein, Second circuit 242 is opened first switch 27 earlier; Make power supply unit 20 power supply give power control circuit 22, then power control circuit 22 can be supplied with the required power supply of first circuit 241, then second circuit 242 again through and the interface of 241 in first circuit; Transfer instruction to be to wake first circuit 241 up, by this power supply control tuner 11, the Sound Processor Unit 13 and television decoder 15 that are provided of first circuit, 241 power control circuits 22 capable of using.
When audio-video system 2 was opened, second circuit 242 conductings first switch 27 was so that power supply unit 20 provides power supply in tuner 11, Sound Processor Unit 13, television decoder 15 and first circuit 241 via power control circuit 22.When audio-video system 2 is closed, second circuit 242 not conductings first switch 27, therefore power supply unit 20 capable of blocking provides voltage in power control circuit 22, reaches the effect of real power saving.
Because second circuit 242 has timing function and responsible receiving inputted signal; Button control like control of remote controller or audio-video system 2; Therefore second circuit 242 must remain at any time under the operating state; That is to say that no matter whether audio-video system 2 starts shooting, the power supply of second circuit 242 all must constantly be supplied.Therefore the present invention separates the power supply supply of first circuit 241 in the master control integrated circuit 24 with second circuit 242, even audio-video system 2 is under the closing state, battery 26 still can constantly provide power supply to second circuit 242.
In addition; Detector 28 is arranged at second circuit 242 inside and is coupled in second circuit 242 and battery 26; If detector 28 detects the voltage of battery 26 when being lower than predeterminated voltage; Second circuit 242 then can conducting second switch 29, so that 26 chargings of 20 pairs of batteries of power supply unit can make second circuit 242 operate normally to guarantee battery 26.Perhaps, whether second circuit 242 reaches the scheduled time according to the time span that the timer in it 243 is calculated, and conducting second switch 29 in the fixed cycle is periodically to charge to battery 26.
Audio-video system of the present invention can be TV or other multimedia play system; Like DVD; Even the general electronic product that needs to use power supply, all can use power control system of the present invention, reach the effect of saving power supply; And the electronic installation that is coupled in power control circuit 22 is not limited to tuner 11, Sound Processor Unit 13, television decoder 15, also can be other electronic installation.Second circuit 242 can be micro controller unit, controls the running of whole audio-video system 2.But power supply unit 20 is the power supply unit of automatically converting voltage.
The framework of audio-video system of the present invention can be blocked the path that power supply unit provides power supply fully when not operating, to reach real less electricity consumption.In addition, add the accumulation pond, give micro controller unit with the specialize in supply power supply, so audio-video system is not when operating, micro controller unit still can be possessed electric power, with receiving inputted signal or carry out function such as timing, uses letting the normal operation of audio-video system ability.
The above is merely preferred embodiment of the present invention, and all equalizations of being done according to claim scope of the present invention change and modify, and all should belong to covering scope of the present invention.
