Fig. 3 is the structural representation of the embodiment two of the device of automatic shutdown of the present invention.
Embodiment
As described in the background art, existing TV cannot realize automatic shutdown, thus causes the problem that waste of energy and impact are had a rest.
And the invention provides a kind of method and device of automatic shutdown, single audio frequency is determined whether by carrying out analysis to environmental volume, if single audio frequency then judges that whether loudness value is for being within the scope of default loudness, if the loudness value of current environment volume is in more stable state all the time, then show that user is in sleep state, thus realize automatic shutdown.
For enabling above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail specific embodiments of the invention below in conjunction with accompanying drawing.
Fig. 1 shows the schematic flow sheet of the method for automatic shutdown of the present invention; With reference to figure 1, the method for described automatic shutdown, comprising:
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, other harvesters can also be utilized to gather the volume in current environment.
Step S2, judges whether current environment volume is single audio frequency;
Under normal circumstances, the sound in environment should be noisy and unordered, and TV programme generally is regular voice or dub in background music or various audio, if only have single audio frequency in environment, may be that user enters sleep state in most cases.Therefore, initial decision can be carried out by whether only having in current environment single audio frequency.If when current environment volume is not single audio frequency, then illustrates that user is in active state, so, return and perform step S1, continue to gather environmental volume.
When current environment volume is single audio frequency, then performs step S3, judge whether the loudness value of current environment volume is within the scope of default loudness;
Under normal circumstances, the mean loudness of TV programme is general all more stable and amplitude of variation can not be very large, when program finishes playing middle commercial breaks or switching channels time the mean loudness of the ambient sound collected general then difference can be larger.In addition, when TV reception, during switching channels, usually all can there is the noiseless situation of transience.
Therefore, when the loudness value of current environment volume is within the scope of default loudness, show not switch TV programme, all the time same channel is in, add the single audio frequency only having TV programme, so can confirm that user is in sleep state, so, perform step S4, send the first control command with closing television machine.
Certainly, to the loudness value of current environment volume be in default loudness scope judge time, need to analyze the environmental volume in the long period, otherwise there will be false judgment.Analyze as the environmental volume in how long and the data such as default loudness scope all can reasonably be arranged according to actual needs, the present invention does not limit this.
Preferably; before execution step S4 closing television machine, can also remind user in advance, as passed through prompt tone or playing the forms such as frame; those skilled in the art can also be reminded by other alerting pattern, and this all should fall into scope.
The method of the automatic shutdown of the present embodiment, can carry out automatic shutdown to television set more timely by carrying out analysis to environmental volume and its loudness value.Its method is simple and efficient, and with low cost.The automatic shutdown of TV can be realized by this easy mode.
In other embodiments, the method for described automatic shutdown before judging whether current environment volume is single audio frequency, can also judge whether current environment volume exceedes threshold value; If when current environment volume is less than threshold value, then then judge whether current environment volume is single audio frequency; If when current environment volume is greater than or equal to threshold value, then send the second control command to reduce the volume of television set.
If current environment volume is very large, such as, when being greater than 90 decibels, can first the volume of TV programme be reduced, the noise caused too greatly with the volume eliminated due to television set.If be less than predetermined threshold value, then then can perform the judgement of single audio frequency.
By can noise be effectively reduced to the adjustment of environmental volume, and automatically can complete volume adjusting, not need manual operation, improve Consumer's Experience.
With reference to figure 2, the present invention also provides a kind of device of automatic shutdown, and described device comprises:
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, judges whether the loudness value of current environment volume is within the scope of default loudness;
First control unit 40, for when the loudness value of current environment volume is within the scope of default loudness, sends the first control command with closing television machine.
In a particular embodiment, described collecting unit can be the microphone in mobile terminal.First control unit 40 can send infrared ray to control the closedown of television set.Certainly, those skilled in the art can also do other simply distortion or displacements, and the present invention does not limit this.
With reference to figure 3, in another embodiment, the device of described automatic shutdown can also comprise: the 3rd judging unit 50 and the second control unit 60.
Described 3rd judging unit 50, connects described collecting unit 10 and the first judging unit 20, for judging whether current environment volume exceedes threshold value;
Described first judging unit 20, for when current environment volume is less than threshold value, judges whether current environment volume is single audio frequency.
Described second control unit 60 connects described 3rd judging unit 50, for when current environment volume is greater than or equal to threshold value, sends the second control command to reduce the volume of television set.
The device of automatic shutdown of the present invention, carries out analysis by each judging unit to current environment volume and judges, when current environment is only single audio frequency, and when loudness value is within the scope of default loudness all the time, confirms that user enters sleep, thus automatic shutdown.The device of automatic shutdown of the present invention realizes simple, easy to use, and can not increase too large cost.
Although the present invention discloses as above, the present invention is not defined in this.Any those skilled in the art, without departing from the spirit and scope of the present invention, all can make various changes or modifications, and therefore protection scope of the present invention should be as the criterion with claim limited range.
