In the present embodiment, by taking equipment is television set as an example, the detailed description of scheme is carried out, other situations are similar therewith, this
Embodiment repeats no more.
An exemplary embodiment of the present disclosure provides a kind of methods of shutdown management, as shown in Figure 1, the processing stream of this method
Journey may include following step:
Step S110 presets the close event of power supply by power sense circuit in multiple power supplys of detection device,
In, default power supply is the power supply before coming the power supply of governor circuit and audio operational amplifier circuit in power supply closing timing.
Wherein, audio operational amplifier circuit is the audio amplification for exporting governor circuit, and play out.Audio amplifier
Circuit includes earpiece audio operational amplifier circuit, loudspeaker audio operational amplifier circuit.
When the power supply of governor circuit is closed, a sharp impulse wave can be generated at once, in Fig. 2, by circle circle
Residence is sharp impulse wave.In embodiments of the present invention, main purpose is in order not to play this impulse wave.
In an implementation, in the mainboard of a television set, including multiple power supplys.Firstly, mainboard can take the alternating current of 220V, taking
After obtaining alternating current, alternating current is carried out by Transformer Rectifier by power circuit, alternating current, which is transformed into other circuits in mainboard, to be made
Power supply.Generally, alternating current can be transformed into the direct current that voltage is 12V, then the direct current that voltage is 12V is continued to turn
It is changed to other common voltage direct currents such as 5V, 3.3V.In closing television machine, these direct currents be not all directly close, and
It is successively to be closed according to certain logic according to timing.Therefore, in order to which during shutdown, power sense circuit energy is first it is detected that be
When no generation power off event, needs to be arranged power sense circuit detection and come governor circuit and sound in power supply closing timing
The close event of power supply before the power supply of frequency operational amplifier circuit, rather than a random power supply.
Optionally, power sense circuit includes first resistor, second resistance, 3rd resistor and triode: first resistor
First pin is connected with default power supply, and the second pin of first resistor is connected with the first pin of second resistance, the second electricity

The second pin ground connection of resistance.
Optionally, power sense circuit further includes voltage-stabiliser tube: the first pin of voltage-stabiliser tube is connected with default power supply, pressure stabilizing
The second pin of pipe is connected with the first pin of first resistor.
In an implementation, as shown in figure 3, power sense circuit includes R1, R2, R3, V1 and VD1.In the circuit, it detects
Power supply be voltage be 5V direct current.In Fig. 3, R1 is first resistor, and R2 is second resistance, and R3 is 3rd resistor, and V1 is
Triode, VD1 are voltage-stabiliser tube.In the case where 5V power supply is not turned off state, R1 and R2 points supply voltage u1 in addition to voltage-stabiliser tube.R1
Get the u11 and u12 of u1 according to the ratio of resistance with R2.Then the voltage of the base stage pin of V1 is identical as the voltage on R2, is
u12.Then, it is believed that the voltage of the base stage pin of V1 is high level, V1 conducting, the electricity for the governor circuit being connected with the emitter-base bandgap grading of V1
The level that source detection pin detects is high level.When 5V power supply is closed, the voltage gradual rolloff of the base stage pin of V1
To 0V, it is believed that the voltage of the base stage pin of V1 is low level, and V1 is not turned on, the power supply for the governor circuit being connected with the emitter-base bandgap grading of V1
Detection pin is in vacant state.Such logic can be set in governor circuit: when detecting that power detecting pin is in
Ground state, it is believed that television set shutdown event has occurred, then carries out step S120.
Optionally, method provided in an embodiment of the present invention further include: the pressure drop of voltage-stabiliser tube is determined by following formula 1:
Wherein, x is the pressure drop of voltage-stabiliser tube, and U is the voltage of default power supply, and R1 is the resistance value of first resistor, and R2 is the second electricity
The resistance value of resistance, △ u are the conducting voltage of triode.
It should be noted that the pressure drop of suitable voltage-stabiliser tube can be obtained, to adjust electricity by choosing voltage-stabiliser tube appropriate
The detection sensitivity of power sense circuit.When voltage of the pressure drop of voltage-stabiliser tube closer to default power supply, the spirit of power sense circuit
Sensitivity is higher.Specifically, the pressure drop of voltage-stabiliser tube first has to the voltage for being less than default power supply.Secondly, when default power supply passes through pressure stabilizing
After pipe, voltage decline if voltage drops too low, will lead to the brownout of the base stage pin of triode, cannot be connected,
Therefore power sense circuit cisco unity malfunction.So by the pressure drop of voltage-stabiliser tube according to the voltage and triode of default power supply
Voltage needed for being connected, determines the pressure drop of voltage-stabiliser tube.It is specific to determine that formula be as shown in formula 1.
As seen from Figure 3, the structure of power sense circuit is simple, and component is fewer, therefore, power sense circuit pair
The reaction of the close event of default power supply will correspondingly rapidly.It in turn, is to strive for before sharp impulse wave plays back
The effective time reacted with processing.
Step S120 cuts off sound of the governor circuit to audio operational amplifier circuit when detecting the close event of default power supply
Frequency exports, so that audio operational amplifier circuit stops playing audio.
In an implementation, as shown in figure 4, the master chip of governor circuit is SoC, the power supply of governor circuit is u3, and R4 is current limliting
Resistance.Power sense circuit is A mute, and power sense circuit includes R1, R2, R3, V1 and VD1, and u1, u2 are power supplies.Sound
Frequency operational amplifier circuit is Headphone.In Headphone, HP P_HP1_L is the left channel audio input pin of first passage,
HP P_HP1_R is the right audio channel input pin of first passage.By taking Headphone as an example, when A mute detects default electricity
When the close event in source, cut off two pin of HP P_HP1_L and HP P_HP1_R from SoC to Headphone audio output.
Between SoC and Headphone, when audio is not present, impulse wave would not be also generated.
Optionally, default power supply is the power supply of timing at first in power supply closing timing.
For example, there are four types of power supplys, respectively 12V, 8V, 5V, 3.3V on mainboard, in power supply closing timing, by most arriving first
The power supply that last sequence is successively closed are as follows: 3.3V, 8V, 5V, 12V.It is thereby possible to select whether detection 3.3V power supply is closed
It closes, before sharp impulse wave plays back, to strive for effectively reacting the time with processing.
The method provided through this embodiment cuts off governor circuit to sound when detecting the close event of default power supply
The audio output of frequency operational amplifier circuit, so that audio operational amplifier circuit stops playing audio.Default power supply is in power supply closing timing
The power supply before the power supply of governor circuit and audio operational amplifier circuit is come, in this manner it is possible in governor circuit and audio amplifier electricity
Before the power supply on road is terminated, the case where first television set shuts down, which checks, comes, and races against time for further processing.In this way,
Immediately before governor circuit closing, audio output of the governor circuit to audio operational amplifier circuit is cut off, when the output of not no audio
When, impulse wave would not be generated, has cut off the possibility that impulse wave generates from root.
