Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
Please refer to Fig. 1, Fig. 1 is the embodiment of the method for a kind of switch mobile phone scene mode of the present inventionFlow chart, the method for switch mobile phone scene mode of the present invention comprises the following steps:
S1: the current environment of living in of mobile phone is detected, obtain PCM corresponding to current environment of living inValue;
S2: inquiry is preset in scene mode in mobile phone and the mapping table of PCM threshold value, determines PCMBe worth corresponding scene mode;
S3: current scene mode is switched to scene mode corresponding to PCM value.
Wherein, before step S1, need to first obtain PCM value corresponding to various varying environments, toolBody please refer to Fig. 2, and the method for obtaining PCM value corresponding to various varying environments specifically comprises following stepRapid:
S11: gather the audio signal of mobile phone under different scenes;
S12: audio signal is carried out to statistical disposition, to obtain reflecting of scene mode and PCM threshold valueFiring table;
S13: the mapping table of storage scenarios pattern and PCM threshold value.
Wherein, in step S11, what collect is the mechanic sound Boeing under extraneous different sceneFrequently signal, and further change into analog electrical signal.
Wherein, in step S12, need to unite to the audio signal collecting in step S11Meter is processed, and concrete processing procedure please refer to Fig. 3, and Fig. 3 is the concrete processing of S12 step in Fig. 2Operation, it comprises the following steps:
S211: in the same period, Same Scene is fixed to the repeated detection of duration, at every turn inspectionSurvey correspondence and obtain a PCM value, multiple PCM values that repeated detection is obtained are done on average, withTo the mean value of the PCM value corresponding with this period;
S212: in the different periods, Same Scene is repeated the detection of step S211, Mei GeshiSection correspondence obtains a mean value;
S213: multiple mean value is carried out to statistical disposition, obtain PCM threshold corresponding to Same SceneValue;
S214: every kind of different scene is carried out respectively to above-mentioned steps S211, S212 and S213Detection, to obtain PCM threshold value corresponding to each different scene;
S215: different scenes is named.
Wherein, PCM (Pulse-codemodulation, pulse code modulation) is from mould soundAnalog signal converts a kind of technology of data signal to, and the process of obtaining PCM value is: receiving stepAnalog electrical signal in S11, and amplifying, finally use a fixing frequency as 8KHz orPerson 16KHz samples to analog electrical signal, and the waveform of the signal after sampling is just as a string continuousThe pulse that amplitude differs, the amplitude of these pulses by certain precision quantize, coding etc.,Storage medium is exported, is transmitted, processed or be recorded to numerical value after these quantifications, coding continuouslyIn. Obtain the data signal of 8 bits by said process, corresponding decimal value is 0～255PCM value.
In step S213, PCM threshold value is to having a lower limit and a higher limit. To be manyIndividual mean value carries out statistical disposition several different methods, for example, can be, will in step S212, obtainThe minimum two or more mean values that obtain do average treatment again, obtain corresponding PCMThe lower limit of threshold value; Two or more mean values of maximum are done to average treatment again, obtainThe higher limit of corresponding PCM threshold value.
In step S215, different scenes is named and is specially: every kind of corresponding life of sceneA kind of scene mode by name, by each scene mode and corresponding PCM threshold value correspondence mappings, byThis forms the mapping table of scene mode and PCM threshold value.
Below illustrate and how to obtain the PCM value that various environment are corresponding. For example: with outdoorScape pattern is example, obtains PCM value that outdoor environment is corresponding two of the peak period of can going to work in the morningIn ten minutes, be chosen in a noisy audio signal of detection in every two minutes in the street, simulatedThe signal of telecommunication, and this analog electrical signal is changed into by operations such as amplification, sample quantization and codingsPCM value, then does on average detecting ten PCM values that obtain in 20 minutes for ten times, with mustGo to work to the morning mean value of PCM value corresponding to period, is made as D1.
Then more quiet the street repeats above-mentioned detection more in the afternoon, obtains quiet street in afternoonThe mean value of the PCM value that road is corresponding, is made as D2. Carry out after the same method same test,Obtain the mean value of the different PCM value of outdoor environment, as D3, D4 and D5.
Then by mean value D1, the D2 of PCM values different outdoor environment obtained above, D3,D4 and D5 do on average again, to obtain PCM threshold value. For example can two of minimum are averageValue is done the lower limit that on average obtains PCM threshold value, and two mean values of maximum are done on average, obtains PCMThe upper limit of threshold value. Thus, the mapping that obtains outdoor pattern and the PCM threshold value corresponding with it is closedSystem.
In like manner, detect other patterns, for example mode standard, silent mode by above-mentioned same methodOr the PCM threshold value that conference model etc. are corresponding, corresponding respectively with it to obtain different scenesThe mapping table of PCM threshold value, as shown in table 1.
Finally different scenes with its respectively the mapping table of corresponding PCM threshold value store memory intoIn.
Table 1: scene mode and corresponding PCM threshold value thereof
| Scene mode | PCM threshold value (upper limit) | PCM threshold value (lower limit) |
| Mode standard | A0 | A1 |
| Silent mode | B0 | B1 |
| Conference model | C0 | C1 |
| Outdoor pattern | D0 | D1 |
Described in brought forward, in the present invention, after need to obtaining in advance the PCM value that various environment are correspondingJust can carry out the switching of the scene mode of mobile phone, shown in Fig. 1:
Pre-stored different scenes and its mapping table of corresponding PCM threshold value respectively in mobile phoneAfter, in step S1: after mobile phone power-on, automatically open the time interval of sound-recording function to presetThe current environment of living in of mobile phone is detected, to obtain the PCM value that current environment of living in is corresponding.
Wherein, the time interval is set by the user, such as being set as about detection per minute once,Or select a bit of time after mobile phone and base station periodic synchronous complete to detect, hand like thisThe power consumption of machine system does not almost increase, and has promoted user's experience.
Wherein, the process of obtaining PCM value is the same with the process described in Fig. 3, no longer superfluous at thisState.
In step S2, be more than or equal to a certain when inquiring the PCM value that current environment of living in is correspondingThe minimum of a value of PCM threshold value and while being less than or equal to the maximum of this PCM threshold value, judges this PCMBeing worth corresponding scene mode is the corresponding scene mode of this PCM threshold value.
For example, be more than or equal to the A1 in table 1 when inquiring the PCM value that current environment of living in is correspondingValue, and be less than or equal to the A0 value in table 1, scene mode corresponding to this PCM value is higher limitFor A0 and lower limit are the corresponding standard scene mode of A1.
The determination methods of other scene mode is the same with standard scene mode, no longer superfluous at thisState.
In step S3, according to scene mode corresponding to PCM value definite in step S2, controlCurrent scene mode is automatically switched to scene mode corresponding to this PCM value by mobile phone processed.
