Embodiment
As described in the background art, existing TV can not realize automatic shutdown, thus cause waste of energy and
The problem of influencing rest.
And the present invention provides a kind of method and device of automatic shutdown, judged whether by carrying out analysis to environmental volume
For single audio frequency, then judge whether loudness value is in default loudness scope, if current environment volume if single audio frequency
Loudness value is in more stable state all the time, then shows that user is in sleep state, so as to fulfill automatic shutdown.
It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings to the present invention
Specific embodiment be described in detail.
Fig. 1 shows the flow diagram of the method for automatic shutdown of the present invention；With reference to figure 1, the method for the automatic shutdown,
Including：
Step S1, gathers the volume in current environment；
In a particular embodiment, the volume in the microphone collection current environment in mobile terminal can be utilized.Certainly, also
The volume in current environment can be gathered using other harvesters.
Step S2, judges whether current environment volume is single audio frequency；
Under normal conditions, the sound in environment should be noisy and unordered, and TV programme generally are regular
Voice is either dubbed in background music or various audios, is probably that user comes into most cases if there was only single audio frequency in environment
Sleep state.Therefore, can be by whether only having single audio frequency to carry out initial decision in current environment.If current environment volume
When not being single audio frequency, then illustrate that user is active, then, return and perform step S1, continue to gather environmental volume.
When current environment volume is single audio frequency, step S3 is then performed, judging the loudness value of current environment volume is
It is no to be in default loudness scope；
Under normal circumstances, the mean loudness of TV programme is generally all more stable and amplitude of variation will not be very big, and
Program finish playing the middle ambient sound collected when breaking for commercialsy or during switching channels mean loudness it is generally then poor
Different meeting is bigger.In addition, when TV reception, the noiseless situation of transience, usually can all occur in whens switching channels.
Therefore, when the loudness value of current environment volume is in default loudness scope, show not to TV programme into
Row switching, all the time in same channel, along with the single audio frequency of only TV programme, it is possible to confirm that user is in sleep
State, then, step S4 is performed, sends the first control instruction with closing television machine.
Certainly, the loudness value of current environment volume is in when default loudness scope judges, it is necessary to the long period
Interior environmental volume is analyzed, and false judgment otherwise occurs.As for how long interior environmental volume analyzed with
And the data such as default loudness scope can reasonably be set according to being actually needed, the present invention is without limitation.
It is preferred that before step S4 closing television machines are performed, user can also be reminded in advance, such as pass through prompting
Form, the those skilled in the art such as sound or bullet frame can also be reminded by other alerting patterns, this should all fall
Enter the scope of the present invention.
The method of the automatic shutdown of the present embodiment, can be compared by carrying out analysis to environmental volume and its loudness value and
When to television set carry out automatic shutdown.Its method is simple and efficient, and of low cost.It can be achieved by this easy mode
The automatic shutdown of TV.
In other embodiments, the method for the automatic shutdown can also judge whether current environment volume is single sound
Before frequency, judge whether current environment volume exceedes threshold value；If current environment volume is less than threshold value, then judge to work as front ring
Whether border volume is single audio frequency；If current environment volume is more than or equal to threshold value, the second control instruction is sent to drop
The volume of low television set.
If current environment volume is very big, when being greater than 90 decibels, first the volume of TV programme can be reduced, to eliminate
The noise caused by the volume of television set is too big.If less than predetermined threshold value, sentencing for single audio frequency can be then performed
It is disconnected.
Noise can be effectively reduced by the adjusting to environmental volume, and volume adjustment can be automatically performed, it is not necessary to
Manual operation, improves user experience.
With reference to figure 2, the present invention also provides a kind of device of automatic shutdown, described device includes：
Collecting unit 10, for gathering the volume in current environment；
First judging unit 20, for judging whether current environment volume is single audio frequency；
Second judging unit 30, for when current environment volume is single audio frequency, judging the loudness of current environment volume
Whether value is in default loudness scope；
First control unit 40, for when the loudness value of current environment volume is in default loudness scope, sending the
One control instruction is with closing television machine.
In a particular embodiment, the collecting unit can be the microphone in mobile terminal.First control unit 40 can
The closing of television set is controlled to send infrared ray.Certainly, those skilled in the art can also do other simple deformations or
Displacement, the present invention are without limitation.
With reference to figure 3, in another embodiment, the device of the automatic shutdown can also include：3rd judging unit, 50 He
Second control unit 60.
3rd judging unit 50, connects 10 and first judging unit 20 of collecting unit, for judging to work as front ring
Whether border volume exceedes threshold value；
First judging unit 20 be used for when current environment volume is less than threshold value, judge current environment volume whether be
Single audio frequency.
Second control unit 60 connects the 3rd judging unit 50, for when current environment volume is more than or waits
When threshold value, the second control instruction is sent to reduce the volume of television set.
The device of the automatic shutdown of the present invention, analysis judgement is carried out by each judging unit to current environment volume, when
Current environment is only single audio frequency, and loudness value confirms that user enters sleep all the time in when presetting in loudness scope, so that from
Dynamic shutdown.The device of the automatic shutdown of the present invention is realized simply, easy to use, and will not increase too big cost.
Although present disclosure is as above, the present invention is not limited to this.Any those skilled in the art, are not departing from this
In the spirit and scope of invention, it can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
Subject to the scope of restriction.
