and S10, collecting the fingerprint of the operator.
In this embodiment, the fingerprint of the operator is collected by the existing fingerprint collection module.
And S20, judging whether the fingerprint of the operator belongs to the family member and the child through a preset family member fingerprint identification model. If the operator does not belong to the family member, executing the step S30; if the operator belongs to the family member and belongs to the child, executing the step S50; if the operator belongs to a family member but not a child, step S60 is performed.

The size of the fingers is also larger than that of a child, so that the range of a touch area when the air conditioner is operated is larger than that of the child, and whether the operator is the child or not can be judged through the behavior characteristic.
In another embodiment, the touch area detection module is used for judging whether the operator belongs to a child, and the specific detection method can be used for detecting through the pressure distribution measurement system.
Any one of the three behavior characteristics, namely the operation speed, the touch force and the touch area has a certain error, but the three behavior characteristics are combined together, so that the judgment error can be greatly reduced.
The detection processes of the operation flexibility detection module, the touch force detection module and the touch area detection module are as follows:

When the input signals of the operation flexibility, the touch force and the touch area are input, the trained classifier is used for classifying and deciding the input signals respectively, and whether the input signals belong to signals of children or not is judged.
The present embodiment uses SVM classifiers, and in other embodiments, other classifiers such as Random Forest (RF), k-nearest neighbor (kNN), etc. may be used.
The centralized control method of the energy-saving control system of the central air conditioner also comprises the following steps:

And S80, the control module switches the air conditioner to the sleep mode.
The air conditioner in the room is still on but there is no sound in the room, and there are generally two cases: the person in the room goes to bed or goes out for a short time. When the sound collection module cannot detect sound within T time, the air conditioner is automatically switched to a sleep mode, so that the energy-saving effect is achieved.
In this example, T is 10 minutes, and in other embodiments, the value of T may be adjusted according to the habits of the family members.
And S90, separating the collected sound into different types of sound categories.
In this embodiment, the collected sounds are separated by the sound separation module, and the separation process of the sound separation module is implemented based on Hilbert transform, and the specific process is as follows:
and S91, carrying out denoising pretreatment on the collected indoor mixed sound signal.
And S92, performing Hilbert transform on the denoised sound.
And S93, carrying out differential processing on the converted signal, and synthesizing the signal obtained after the differential processing and the collected sound signal to form a non-underdetermined sound signal.
S94, determining the number of source sound signals based on the underdetermined sound signals.

And S96, carrying out independent component analysis on the proper signals and separating out the source sound signals.
The separation method adopted by the embodiment is suitable for various source sound signals, and has good noise resistance.
And S100, positioning each separated sound.

If the separated sound contains the sound of the child, executing the steps S50 and S120; if the separated sound does not include the sound of the child, step S60 is executed.
Although the age recognition model can detect whether the operator is a child, it cannot detect whether a child is present indoors under the following conditions:
in the first case, the operator is a child, but the three behavioral characteristics of the operator just avoid the behavioral characteristics of the child;
in the second case, the operator is an adult, but a child is present indoors.
Therefore, whether the separated sound contains the sound of the child or not is judged through the sound identification model, and whether the child exists in a room or not can be judged more accurately. When children exist in the room, the control module reduces the temperature adjusting range of the air conditioner to be between T1 and T2 degrees, so that discomfort of the children caused by overhigh or overlow temperature of the air conditioner is effectively prevented.

When sound signals are input, the trained classifier is used for carrying out classification decision on the input signals, and whether the input signals belong to the sound of children or not is judged.
And S120, adjusting the angle of the air outlet of the air conditioner to enable the air outlet of the air conditioner to avoid the sound source direction of the child.

In this embodiment, the air outlet angle of the air conditioner is adjusted through the control module.
In the embodiment of the application, the sound collection module collects indoor sound, and if the sound cannot be collected within T time, the control module switches the air conditioner to the sleep mode to achieve the effect of energy conservation; if the sound can be collected within the time T, the sound separation module separates the indoor mixed sound into different sound types, the sound source signal microprocessor positions the separated sounds, and the sound recognition model judges whether the separated sounds contain the sound of the child; when the separated sound is judged to contain the sound of the child, the control module reduces the temperature adjusting range of the air conditioner to be between T1 and T2 degrees, meanwhile, the control module receives the sound positioning information of the sound source signal microprocessor, and then the air outlet angle of the air conditioner is adjusted to enable the air outlet of the air conditioner to avoid the sound source direction of the child, so that the condition that the body of the child is uncomfortable is effectively prevented.
