S404:Judge whether whole scan completes, if so, perform S405, otherwise, repeat S403 and its follow-up step Suddenly.
Wherein, the number of times of whole scan can be multiple, such as 5 times, then show that the overall situation is swept when completing 5 whole scans Retouch and complete, otherwise whole scan is not completed.
S405:Obtain ambient temperature threshold value.
For example, after the completion of each whole scan, all temperature values that can be obtained according to scanning calculate mean value.
S406:Obtain the positional information of thermal source.
In the present embodiment, thermal source refers to the thermal source for belonging to people.
For example, each whole scan can be corresponded to, it is determined that once belonging to the positional information of the thermal source of people.
Wherein, in a whole scan, according to being averagely worth to ambient temperature threshold value, then each temperature value can be calculated With the difference of ambient temperature threshold value, if difference is more than preset difference value, temperature value is the temperature value of thermal source, furthermore it is also possible to The area of thermal source is determined according to the positional information of thermal source, when area is more than preset area, then thermal source is belonging to the thermal source of people, and Corresponding positional information is obtained according to the coordinate value of the Temperature Distribution matrix of thermal source.

Again for example, with reference to Fig. 7, when the distance of two thermals source becomes big, barycentric coodinates change.As two people initially sit In the closer distance of sofa, after a while two people seat is distant, or wherein a people leaves.
S410:Judge that the sweep limits after reducing, whether more than default short scan, if so, repeats S408 And its subsequent step, otherwise, perform S411.
For example, default short scan is:Scanning angle is 1.2*Ang, and scanning angle after diminution is more than During 1.2*Ang, if barycentric coodinates do not change, sweep limits can be continued to zoom out.
S411:The sweep limits for keeping infrared sensor array is minimum sweep limits.
For example, when the scanning angle after diminution is less than 1.2*Ang, if barycentric coodinates do not change, scan angle is kept Degree is 1.2*Ang.
S412:Judge whether the time for reaching again whole scan, if so, repeat S403 and its subsequent step, it is no Then repeat S408 and its subsequent step.
Wherein it is possible to the cycle of advance equipment whole scan, for example, carried out once the overall situation and sweep every 3 minutes or 5 minutes Retouch, when the time apart from last time whole scan the cycle time of default whole scan is exceeded, then reach whole scan again Time.
In addition, when it is minimum sweep limits to keep scanning angle, the sweep limits after the correspondence in S409 reduces has Body refers to the minimum sweep limits of holding.
In addition, the present embodiment after the sweep limits for narrowing down to minimum as a example by judging whether to reach the whole scan time, also Can judge whether to reach the whole scan time after sweep limits is reduced every time, or judge whether center of gravity changes every time Judge whether to reach whole scan time etc. after change.
S413:Judge whether newly-increased thermal source occur, if so, repeat S403 and its subsequent step, otherwise, perform S414。
Wherein, it can be caused by newly-increased thermal source that heating source area changes;Or, or original thermal source state change Caused afterwards, for example, people kicks quilt heating source area after son and becomes big, and the present embodiment can be used for kicking quilt sub- detection so as to control air-supply side To, it is to avoid user catches a cold.
Specifically, the location distribution information of thermal source can be determined according to the positional information of thermal source, according to location distribution information The number of thermal source is can determine that, is that thermal source takes first area and second area according to location distribution information for example, if the Position difference between one region and second area is in preset range, it is believed that be a thermal source, is otherwise two thermals source.
The number of the thermal source detected during according to different scanning process, it may be determined that newly-increased thermal source whether occur, for example, works as heat When source number increases, show newly-increased thermal source occur.
S414:Judge whether current sweep limits is whole scan scope, if so, repeat S403 and its follow-up step Suddenly, otherwise, S415 is performed.
S415:Amplify the sweep limits of infrared sensor array.
