As shown in fig. 1, an air conditioner internal unit control device according to an embodiment of the present invention includes: the air conditioner comprises an air conditioner main controller 1, a sub-controller 2, an infrared sensor 3 and a distance detection device 4; infrared sensor 3 and distance detection device 4 set up and gather user's infrared sensing signal and distance signal respectively on the air conditioner to signal transmission to sub-controller 2 that will gather, sub-controller 2 receives the signal that infrared sensor 3 and distance detection device 4 gathered, sends to air conditioner main control unit 1 after handling, and air conditioner main control unit 1 is according to the air-out wind speed and the mode of the signal control air conditioner of sub-controller 2 transmission.
The air conditioner main controller 1 is mainly used for controlling the air outlet speed and the working mode of the air conditioner, the sub-controller 2 is mainly used for controlling the opening of the receiving infrared sensor 3 and the distance detection device 4, and transmitting signals sent and received by the receiving infrared sensor 3 and the distance detection device 4 to the air conditioner main controller 1 after processing, so that the air outlet speed and the working mode of the whole air conditioner are controlled.
When the user moves to an area near the air outlet of the air conditioner, infrared rays radiated by an infrared imaging induction target (namely, the user) of the infrared sensor 3 are used for detecting whether a person is in a set detection area or not in real time. The infrared sensor 3 transmits and receives signals and feeds the signals back to the sub-controller 2 for discrimination. When the signal fed back by the infrared sensor 3 shows that a user appears in the detection area, the sub-controller 2 issues a control instruction to control the distance detection device 4 to detect the distance between the user and the air outlet of the air conditioner. The distance detection device 4 is a sensor that can measure a distance, and for example, can calculate a distance to an object (i.e., a user) by emitting an energy beam and reflecting the energy beam by the object (i.e., the user) to be measured, and calculating a time when the energy beam is emitted to be reflected by the object (i.e., the user).

According to the distance degree from the air outlet of the air conditioner, the detection area is divided into different areas, according to the distance signal from the user to the air outlet of the air conditioner, fed back by the distance detection device 4, the air conditioner main controller 1 determines the area where the user is located, and correspondingly controls the air outlet speed of the air conditioner.
Specifically, at least three regions S1, S2 and S3 may be divided according to the distance from the air outlet, where Smin < S1< S2< S3< Smax, where Smin is a preset minimum detection region and Smax is a preset maximum detection region. Of course, the three area divisions are only examples, and more areas can be specifically divided, so that more detailed wind speed control can be realized.
According to the distance between the user and the air outlet, the sub-controller 2 feeds back different signals to the air conditioner main controller 1, so that the air conditioner main controller 1 controls the air conditioner air outlet speeds to be delta n1, delta n2 and delta n3 for different areas S1, S2 and S3, Nmin < delta n1< delta n2< delta n3< Nmax, wherein Nmin is a preset lowest air outlet speed, and Nmax is a preset highest air outlet speed.
