Abstract
The invention discloses a TV volume intelligent control method which comprises the following steps: a, a system is initialized and collocation information is loaded; b, the function for intelligently controlling the volume is judged whether to be opened or not; if yes, then step c is carried out; if not, then a TV normal playing menu is carried out; c, an external noise signal is picked, amplified and then sent to the AD conversion terminal of a CPU central processing unit together with a local audio signal; d, the extent of the signal after AD conversion is compared by the CPU to obtain a pre-adjusting factor; then the pre-adjusting factor is multiplied with the compensation value of the function for intelligently controlling the volume preset by a user and then is correspondingly converted into an adjusting factor; e, after the adjusting factor is multiplied with a volume control gene set by the user, the adjusting factor is sent to a volume adjusting unit for adjusting. In the invention, the hearing ability of a person can be better protected by loading the function for intelligently controlling the volume in a TV system and intelligently adjusting the volume of the TV aiming at the noise magnitude of an outside environment; simultaneously, the noise pollution of the outside environment is reduced and the living quality of residents is greatly improved.
Description
Technical field
The present invention relates to TV technology, relate in particular to a kind of intelligent control method for television volume.
Background technology
General television set has become one of the most basic electrical equipment of Chinese family at present, sees that TV programme is an indispensable part in Chinese common people's life already.Adjustment to sound in the television system generally all is that the user goes up the purpose that the adjustment volume reaches the control volume by remote control or panel key at OSD (On Screen Display), perhaps the design phase producer in the engineering menu, reach the purpose that volume is adjusted by adjusting the volume curve, can be constant always after adjusting like this, till user's intervention once more.Because people's ear is closely related with the environmental background noise level for the susceptibility of sound, the environment that noise is big more needs louder volume could guarantee to catch more, only needs little volume just can satisfy the demand in lower noise environment.But the sensitivity of people's ear has conscious adjusting and adaptive functions, often can not recognize in the stimulation that lays oneself open to a high-decibel, goes down to injure hearing for a long time like this; The manufacturing environment noise also can influence the surrounding enviroment quality.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method of adjusting the tv volume size according to external environment noise level intelligence.
For solving the problems of the technologies described above, the objective of the invention is to be achieved through the following technical solutions.
A kind of intelligent control method for television volume may further comprise the steps:
A: system initialization, load configuration information;
B: judge whether the Based Intelligent Control volume functions opens, if enter step c; Otherwise, enter TV normal play picture;
C: send CPU CPU AD end of convert together with this machine audio signal after picking up ambient noise signal processing and amplifying;
D:CPU obtains the preconditioning factor to its amplitude of AD conversion back signal comparison, and the Based Intelligent Control volume functions offset of setting with the user corresponding conversion that multiplies each other is a regulatory factor then;
E: this regulatory factor send sound volume regulation unit to regulate after multiplying each other with the predefined volume controlling elements of user.
Wherein, the adjusting controlled quentity controlled variable of final volume has been introduced the quantization scaling factor between ambient noise signal and this machine audio signal among the step e, and this adjusting controlled quentity controlled variable can be regulated by the user, and OSD goes up Based Intelligent Control volume functions compensation progress bar and Based Intelligent Control volume functions startup raft value progress bar is realized intervening.
Wherein, the user is by selecting to open or close the Based Intelligent Control volume functions by teleswitch or panel button.
Above technical scheme as can be seen, the present invention has following beneficial effect:
The present invention is by loading a Based Intelligent Control volume functions in television system, size at the external environment noise is intelligently adjusted the television sound volume size, thereby can well protect people's hearing, also reduce the pollution of ambient noise simultaneously, improve resident's quality of life greatly; In addition, because the introducing of the factor that the external environment noise is regulated as volume, also have some improvement for the inconsistent problem of volume between the different program source.
Description of drawings
Fig. 1 is Based Intelligent Control volume circuit figure among the present invention;
Fig. 2 is the inventive method flow chart.
Embodiment
Sound gives people's sensation relatively fuzzyyer and blunt in the very big environment of brouhaha; need transfer to very loud people can hear; but under quiet environment; volume transfers to very little sound people and just can hear; if so can be according to the conversion of surrounding environment; the height of environmental noise changed the size of television sound volume is carried out intelligence correction, so will green and environmental protection, and can protect people's hearing.
For ease of the present invention is further understood, now reach specific embodiment in conjunction with the accompanying drawings and describe the present invention.
See also shown in Figure 2ly, comprising:
Step 201: system initialization, load configuration information;
Step 202: judge whether the Based Intelligent Control volume functions opens, if enter step 203; Otherwise, enter step 206;
Step 203: send CPU CPU AD end of convert together with this machine audio signal after picking up ambient noise signal processing and amplifying, as shown in Figure 1;
Step 204:CPU is the preconditioning factor to AD input amplitude corresponding conversion; The setting that the Based Intelligent Control volume functions starts raft value progress bar on this preconditioning factor and the user OSD compares, and when the preconditioning factor during less than the setting of progress bar, establishing regulatory factor is 1.Otherwise regulatory factor equals the set point of Based Intelligent Control volume functions progress bar on the preconditioning factor and the user OSD to multiply each other.
Step 205: after regulatory factor and volume controlling elements multiply each other, send volume to regulate (can be digital-control amplifier, also can be the first DA conversions of voltage-controlled amplifier-voltage-controlled needs);
Step 206: TV normal play.
The control of final volume is with reference to the quantization scaling factor between ambient noise signal and this machine audio signal, and this scale factor can be regulated by the user, and OSD goes up Based Intelligent Control volume functions compensation progress bar and Based Intelligent Control volume functions startup raft value progress bar is realized user intervention.
More than a kind of intelligent control method for television volume provided by the present invention is described in detail, used specific case herein principle of the present invention and execution mode are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
