In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
The invention provides an air conditioner control method.
In a first embodiment of the present invention, as shown in fig. 1, an air conditioner control method includes the steps of:
s100, sending an infrared emission signal;
the infrared emission signals can be sent by one or more infrared signal transceivers, each sent infrared emission signal has a specific detection area, and when a plurality of different infrared signal transceivers send a plurality of infrared emission signals in different directions, the expansion of the detection areas can be realized.
Step S200, receiving an infrared reflection signal;
wherein the infrared reflection signal is generated by reflecting the infrared emission signal. When an obstacle (generally, a user, for simplicity, only the case where the obstacle is the user is considered here, and when the obstacle is not the user, it can be further confirmed from other information of the infrared reflection signal) exists in the detection area of the infrared transmission signal, the infrared transmission signal is reflected to generate an infrared reflection signal, the direction of the infrared reflection signal is correlated with the direction of the infrared transmission signal, and in the case of non-specular reflection, the direction of the infrared reflection signal is considered to be consistent with the direction of the infrared transmission signal, and at this time, the infrared reflection signal is received by the same infrared signal transceiver that transmits the infrared transmission signal, so that the presence of the user in the detection area is inferred.
Step S300, determining the position of a user according to the receiving state of the infrared reflection signal;
when the infrared signal transceiver receives the infrared reflection signal, the position of the user can be deduced according to the information such as the time, the direction, the strength or the code of the received infrared reflection signal, and the information such as whether the user is in a static state or a moving state can be further determined by further combining one or more received infrared reflection signals. When the infrared signal transceiver does not receive any infrared reflected signal, it indicates that there is no user in the detection area.
And S400, adjusting the air outlet parameters of the air conditioner according to the position of the user so as to enable the air outlet of the air conditioner to deviate from the user.
When the position of the user is detected, the air outlet parameter of the air conditioner is adjusted to enable the air outlet of the air conditioner to deviate from the user, and therefore the user is prevented from being ill due to the fact that the air outlet blows directly. Specifically, when the user is in a static state, the air outlet direction of the air conditioner is controlled to deviate from the position where the user is located, when the user is in a moving state, the air outlet direction of the air conditioner is controlled to deviate from the position where the user will move, or when the user is close to the air conditioner, the air conditioner is controlled to change from an air supply mode in which the air outlet direction is unchanged to a wind sweeping mode in which the air outlet direction is constantly changed, so that the user is prevented from being directly blown out for a long time. Furthermore, the air outlet speed of the air conditioner can be adjusted according to the distance between the user and the air conditioner, and when the distance between the user and the air conditioner is short, the air outlet speed is reduced; when the user is far away from the air conditioner, the air outlet speed is increased to meet the comfort requirement of the user, and the following text will explain in detail. And when detecting that no user is in front of the air conditioner, the air conditioner can be controlled to operate in an unmanned mode, and the power consumption of the air conditioner is reduced by reducing the air outlet speed and the like so as to save energy.
As shown in fig. 2, a plurality of infrared signal transceivers 100 are provided on a front panel 500 of the air conditioner, and each infrared signal transceiver 100 determines the position of a user according to a receiving state of an infrared reflection signal by transmitting an infrared transmission signal to a detection area thereof and receiving an infrared reflection signal. For example, each infrared signal transceiver 100 transmits an infrared transmission signal in real time and receives an infrared reflection signal in real time; of course, each infrared signal transceiver 100 may simultaneously transmit an infrared transmission signal and receive an infrared reflection signal upon receiving an instruction to detect a user. When a user is present in the detection area of the leftmost infrared signal transceiver 100, the leftmost infrared signal transceiver 100 will receive the infrared reflection signal, while the other infrared signal transceivers 100 do not receive the infrared reflection signal, thereby determining that a user is present in the front left of the air conditioner. It should be noted that there may be a certain overlap of the detection areas of two adjacent infrared signal transceivers 100, for example, when the user is located right in front of the front panel of the air conditioner, two infrared signal transceivers 100 located in the middle may both be able to receive the infrared reflection signal, and the other infrared signal transceivers 100 may not be able to receive the infrared reflection signal, thereby determining the position of the user located in the middle of the front of the air conditioner. And further adjusting the air outlet parameters of the air conditioner according to the position of the user so as to meet the comfort requirement of the user.
In the technical scheme of the invention, the air conditioner control method comprises the following steps: sending an infrared emission signal; receiving an infrared reflection signal, wherein the infrared reflection signal is generated by reflecting the infrared emission signal; determining the position of a user according to the receiving state of the infrared reflection signal; and adjusting the air outlet parameters of the air conditioner according to the user position so that the air outlet of the air conditioner deviates from the user position. The position of the user is determined by sending and receiving the infrared signal, and then the air outlet parameter of the air conditioner is adjusted according to the position of the user.
In the second embodiment of the present invention, as shown in fig. 3, step S300 includes:
step S310, determining a first direction of a user according to the received infrared reflection signal;
step S320, accumulating the duration of the user in the first direction;
step S330, judging whether the duration of the user in the first direction is less than a preset duration;
if yes, executing step S341, and determining a second direction of the user according to the received infrared reflection signal; step S350, determining the moving direction of the user according to the first direction and the second direction;
if not, step S342 determines that the first orientation is the stationary orientation of the user.
For example, as shown in fig. 2, when a user moves from the leftmost side to the rightmost side of the air conditioner, infrared reflection signals are sequentially received from the leftmost infrared signal transceiver module 100 to the rightmost infrared signal transceiver module 100, and the duration of the infrared reflection signals received by the infrared signal transceiver module 100 is less than a preset duration, that is, when the orientation change state of the user is determined through each infrared signal transceiver module 100, the moving direction of the user can be determined according to the orientation change state. When the user is stationary at a certain position in front of the air conditioner, for example, at the left front of the air conditioner, the infrared signal transceiver module 100 located at the leftmost side receives the infrared reflection signal, and the duration of receiving the infrared reflection signal is greater than or equal to the preset duration, so as to determine the stationary position of the user. In a specific example, the preset time period is set to 30 seconds. Of course, when the moving direction of the user is judged, whether the user is in the directional movement can be further determined through the moving time length. For example, when it is detected that the user moves from the first position to the second position within 5 seconds, or when it is detected that the user always moves along the determined direction within 5 seconds, it is determined that the user is in the directional movement, rather than making a random movement with a certain position as a center, so that the accuracy of adjusting the air outlet parameter of the air conditioner is improved, and the frequent change of the air outlet parameter of the air conditioner due to the random movement of the user is avoided.
In the third embodiment of the present invention, as shown in fig. 4, step S400 includes:
step S410, when the static position of the user is determined, judging whether an included angle between the static position of the user and the center normal direction of the front panel of the air conditioner is smaller than a first preset angle or not;
if yes, executing step S421, controlling the air conditioner to sweep air upwards;
if not, the step S422 is executed to control the air conditioner to blow air deviating from the static direction.
The air conditioner has the advantages that the air outlet direction is constant in the air supply mode, the air outlet direction is constantly changed in the air sweeping mode, and the air sweeping speed of the air conditioner is smaller than the air supply speed of the air conditioner. Because the air outlet speed in the right front of the air conditioner is usually larger than the air outlet speed in the side front of the air conditioner, and the air outlet of the air conditioner has a certain divergence angle. Therefore, when the included angle between the static position of the user and the center normal direction of the front panel of the air conditioner is smaller than a first preset angle, the user is relatively closer to the front of the air conditioner and is easily blown out directly, therefore, the air conditioner is controlled to sweep wind upwards at a lower wind speed, and the height of the user is limited, so that the direct blowing of the wind to the user can be effectively avoided. And when the included angle between the central normal directions of the front panel of the air conditioner of the user is larger than or equal to a first preset angle, the user is positioned in the front of the side of the air conditioner, and at the moment, the condition of directly blowing the user can be effectively avoided as long as the air outlet of the air conditioner is controlled to blow to the other side of the user.
In the fourth embodiment of the present invention, as shown in fig. 5, step S400 includes:
step S430, when the static position of the user is determined, judging whether an included angle between the static position of the user and the center normal direction of the front panel of the air conditioner is smaller than a second preset angle;
if yes, executing step S441, controlling the air conditioner to discharge air at a first preset air speed;
if not, step S442 is executed to control the air conditioner to output air at the second preset air speed.
The first preset wind speed is smaller than the second preset wind speed. Similarly, considering that the influence of the air outlet right in front of the air conditioner on the user is larger than the influence of the air outlet right in front of the air conditioner on the user, when the included angle between the static position of the user and the normal direction of the center of the front panel of the air conditioner is smaller than a second preset angle, the user approaches the right in front of the air conditioner, and the air conditioner is controlled to output air at a first lower preset air speed so as to avoid the air output from directly blowing the user; when the included angle between the static position of the user and the center normal direction of the front panel of the air conditioner is larger than or equal to the second preset angle, the user is located in the front of the side of the air conditioner, the influence of air outlet on the user is small, the air conditioner is controlled to output air at the second preset air speed which is higher, the indoor heat exchange speed is accelerated, and the comfort level of the user is improved.
In the fifth embodiment of the present invention, as shown in fig. 6, step S400 includes:
step S450, when the moving direction of the user is determined, calculating the end point direction of the moving direction;
and step S460, controlling the air conditioner to supply air from the terminal position.
And calculating the end point direction of the moving direction according to the parameters of the moving direction, the moving speed and the like of the user, so that the air conditioner is controlled to deviate from the end point direction for air supply, and the direct blowing of the user is avoided.
For example, as shown in fig. 2, when it is detected that the user moves from the left front of the air conditioner to the right front, the air conditioner is controlled to blow air to the left front so as to avoid the direction of the end point of the movement of the user, thereby improving the comfort of the user.
In the sixth embodiment of the present invention, as shown in fig. 7, step S300 further includes:
s360, detecting the intensity of the received infrared reflection signal relative to the corresponding infrared emission signal;
step S370: and determining the distance between the user and the air conditioner according to the intensity of the infrared reflection signal relative to the corresponding infrared emission signal.
In the process of transmitting the infrared emission signal and the infrared reflection signal and in the process of reflecting the infrared emission signal, certain attenuation exists, so that the distance between the reflection point and the emission point, namely the distance between the user and the air conditioner can be estimated by detecting the intensity of the infrared reflection signal relative to the infrared emission signal corresponding to the infrared reflection signal, and on the basis of determining the direction of the user, the accurate position of the user is further determined, so that the air conditioner can better adjust the air outlet parameter.
In the seventh embodiment of the present invention, as shown in fig. 8, step S400 includes:
step S470, judging whether the distance between the user and the air conditioner is smaller than a preset distance;
if yes, executing the step S481, and controlling the air conditioner to discharge air at a third preset air speed;
if not, step S482 is executed to control the air conditioner to output air at a fourth preset air speed.
And the third preset wind speed is less than the fourth preset wind speed. According to the distance between the user and the air conditioner, the air outlet speed of the air conditioner is controlled, so that the discomfort of the user caused by the fact that the air outlet of the air conditioner is blown directly to the user is further avoided, and the intelligence of the air conditioner is improved.
There are examples of the present invention that can be combined with each other in the above-described embodiments. For example, as shown in fig. 2, in a specific example, the detection areas corresponding to the infrared signal transceivers are respectively identified as area 1, area 2, area 3 and area 4 from left to right. When the user is detected to be stationary in the area 1, the air conditioner is enabled to supply air to the area 4 at a high-level air speed through an air guide assembly of the air conditioner; when the user is detected to be stationary in the area 2, the air conditioner is enabled to supply air to the area 4 at a low-gear air speed through an air guide assembly of the air conditioner; when the user is detected to be stationary in the area 3, the air conditioner is enabled to supply air to the area 1 at a low-gear air speed through an air guide assembly of the air conditioner; when detecting that the user is located between the area 2 and the area 3, enabling the air conditioner to sweep wind upwards at a low-gear wind speed through a wind guide assembly of the air conditioner; when the user is detected to be stationary in the area 4, the air conditioner is enabled to supply air to the area 1 at a high-level air speed through an air guide assembly of the air conditioner; when detecting that the user moves from the area 1 to the area 4, enabling the air conditioner to supply air to the area 1 at a high-level air speed through an air guide assembly of the air conditioner before the moving direction of the user is not changed; when it is detected that the user moves from area 4 to area 1, the air conditioner is caused to blow air to area 4 at a high level wind speed by the air guide assembly of the air conditioner until the moving direction of the user does not change.
