Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Referring to FIG. 1 , it is a flow chart of an embodiment of the method for controlling a projection display of warm and cold sensations disclosed in the present invention. As shown in the figure, the present invention includes the following steps:

Step S101, dividing the two-dimensional plane of the air-conditioned room into one or more sub-regions. The simplest way to divide is to divide the two-dimensional plane of the air-conditioned room into a complete area. In order to achieve precise control, preferably, the two-dimensional plane of the air-conditioned room is divided into a plurality of sub-regions. The division method can be equal or non-equal. The two-dimensional plane of the air-conditioned room is a two-dimensional plane formed with the length of the air-conditioned room and the width of the air-conditioned room as coordinate axes respectively. The two-dimensional plane of the air-conditioned room can be obtained through manual input, detection by laser ranging sensors, or remote communication.

In step S102, the user's temperature and coldness parameter in at least one sub-area is acquired, and the temperature and coldness parameter is used to reflect the user's comfort level in the current state. The temperature and cold sensation parameters are detected by the infrared sensor installed on the indoor unit of the air conditioner, and the physical parameter represented by it is the body surface heat dissipation of the human body. sense parameters. The specific algorithm for calculating the temperature and cold sensation parameter is not the protection point of the present invention, and will not be repeated here. A common parameter of warmth and coldness is: 0 indicates that the human body feels comfortable, a negative value indicates that the human body feels cold, and a positive value indicates that the human body feels hot. After obtaining the temperature and cold sensation parameters of a certain user, a user ID is allocated to the user, and a one-to-one data relationship between the user ID and the temperature and cold sensation parameters is established and stored in a pre-allocated storage unit. The temperature and cold sensation parameter is a variable that changes with the actual body sensation of the user.

Step S103 , controlling the projection element to project the light color corresponding to the temperature and cold feeling parameter to the user in the sub-area. The temperature and cold sensation parameters after the deviation correction are usually within a set value range, such as [-5, +5]. By default, each temperature and cold sensation parameter corresponds to a light color. For example, negative values correspond to blue, and positive values correspond to red. After detecting the temperature and cold sensation parameters, the user's intuitive comfort feeling is represented by the projection beams of different colors. The projection element is preferably arranged in the upper space directly in front of the indoor unit of the air conditioner, with a height of 2.5 to 3 m, and the position coordinates of the projection element are stored in advance. The projection element is preferably a projection lamp. Toning is preferably in the form of filtering. The projection element may also be a follow spot light or other similar lighting projection device.

As a preferred embodiment of the above-mentioned method for controlling the projection display of feeling of warmth and coldness, if a user is detected in a sub-area, and the parameter of feeling of warmth and coldness of the user is detected. Then, a projection lamp closest to the user is controlled to project to the user in the sub-area with the light color corresponding to the temperature and coolness parameter. When the lamp is lit, its lamp ID is assigned and its position coordinates are called. Establish a data list of projection lamp identification, projection lamp position coordinates, user identification, user coordinates, sub-regions, temperature and cooling parameters and light color, where the temperature and cooling parameters are variables, and the light color changes with the temperature and cooling parameters. If the user moves from one sub-area to another sub-area, the corresponding projection lamp is driven to change the projection angle to realize the tracking of the user. Through the above method, the tracking light display of the user's sense of warmth and coldness in the two-dimensional plane of the air-conditioned room can be realized, which has a good display effect.

As a preferred embodiment of the method for controlling the projection display of warm and cold sensations shown in FIG. 1 , in addition to projection display, the user can also learn the current comfort level through other means, preferably displaying the user comfort level in the form of an image.

After controlling the projection lamp to project on the user with the light color corresponding to the temperature and cooling parameters, the following steps are also included:

Step S204, acquiring the original image of the user. The original image of the user is preferably captured by a high-definition camera. During the whole sampling process, the raw image of each user is preferably only collected once. The acquired original image is added to the one-to-one data relationship between the user ID and the temperature and cold sensation parameters, and another data list is established.

Step S205, calling the display mode corresponding to the temperature and cold sensation parameter. The corresponding relationship between the temperature and cooling parameters and the display mode is set and stored in advance. For example, the display mode may include different color parameters. When the temperature and coolness parameter is 0, the hue value of the display mode corresponds to the angle represented by green in the hue circle. When the temperature and coolness parameter deviates from 0 and falls, the hue value of the display mode rotates clockwise along the hue circle. When the temperature and coolness parameter deviates from 0 and rises, the hue value of the display mode rotates counterclockwise along the hue circle. The amount of rotation corresponds to the falling value and the rising value, and is preferably in a proportional relationship. Depending on the precision of the temperature and coldness parameters, the hue circle for obtaining the hue value of the display mode by default may be a ten-color circle, a twelve-color circle, a sixteen-color circle, a twenty-four hue circle, and the like. In addition to the hue value, the color parameter may also be one or more of an RGB color parameter or a YUV color parameter.

Step S206 , generating a warm-cold feeling image with the same size as the original image, and using part or all of the warm-cold feeling image in a display mode corresponding to the warm and cold feeling parameter. For example, a warm and cool image with the same size as the original image is generated, the background of the warm and cool image is fully transparent, and the whole is modified to the color corresponding to the hue value of the display mode; or part of it is modified to the color corresponding to the display mode The color corresponding to the hue value, or adjust the whole or part of it to other display states, including but not limited to scaling, adding dynamic logos, etc.

Step S207, synthesizing the original image and the warm-cool image and displaying.

With the method for controlling the projection display of warm and cold sensation disclosed in the above-mentioned embodiments of the present invention, by establishing a one-to-one correspondence between the user ID, the warm and cold sensation parameters, the original image and the display mode, in addition to the display mode of the projection lamp, the user can also It can be displayed in an intuitive image way, and the user can understand the influence of the air conditioning adjustment effect on its actual comfort through the image, and improve the user's experience.

In order to reduce the amount of computation and improve the response rate of the display control method, as a preferred embodiment of the control method shown in FIG. 2 , after obtaining the temperature and cooling parameters, first determine the temperature and cooling level of the temperature and cooling parameters, such as being classified as very hot , hot, warm, comfortable, cool, cold, very cold seven levels. After acquiring the original image, call the display mode corresponding to the level of warmth and coldness. Compared with the temperature and cold sensation parameters of the floating format, the magnitude of the warm and cold sensation level is greatly reduced. In the storage unit, the level of warmth and coldness can correspond to a hue value or an RGB value respectively. After the level of warmth and coldness is determined, the corresponding display mode and corresponding hue value or RGB value are directly invoked. Preferably, if the warm and cool feeling levels correspond to one hue value, all the warm and cool feeling levels correspond to the same brightness value and saturation value, so as to ensure the composite display effect and at the same time highlight the difference between the warm and cool feeling levels. After the warm and cool feeling image with the same size as the original image is generated, the overall warm and cool feeling image adopts the display mode corresponding to the warm and cold feeling level. That is, the corresponding hue value, the same lightness value and saturation value are adopted as a whole, and the warm and cool image after adjusting the color and the original image are synthesized for display.

As another preferred mode of the control method for the projection display of warm and cold sensations shown in FIG. 2 . After obtaining the temperature and cold sensation parameters, first determine the temperature and cold sensation levels of the temperature and cold sensation parameters, such as being divided into seven levels: very hot, hot, warm, comfortable, cool, cold, and very cold. After acquiring the original image, call the display mode corresponding to the level of warmth and coldness. Compared with the temperature and cold sensation parameters of the floating format, the magnitude of the warm and cold sensation level is greatly reduced. In the storage unit, the warmth and coldness level may correspond to a temperature and coldness level identifier respectively. The temperature and coldness level identification may be a text identification or a legend identification. After the warm-cool feeling image with the same size as the original image is generated, the warm-cold feeling level indicator is set at a set position on the warm-cool feeling image, such as the center of the image. Warm and cool images use full transparency as the background color. The warm and cold image with the warm and cold feeling level logo is combined with the original image for display.

In order to highlight the display effect of the warm and cold feeling grade mark, in the above control method, in addition to the warm and cold feeling grade corresponding to a warm and cold feeling grade mark, when generating the warm and cold feeling image, it is preferable to call the color corresponding to the warm and cold feeling grade first. parameters, and synthesizing the temperature and cold feeling grade marks and color parameters, so that in the corresponding display mode, the warm and cold feeling grade marks of different warm and cold feeling grades have different color parameters, and the display effect is more direct.

In order to highlight the adjustment effect of the air conditioner, it is a preferred embodiment of the control method shown in FIG. 1 .

Set the effective detection area in the air-conditioned room. In this example, the effective detection area is a fan-shaped area defined by the geometric center of the bottom surface of the indoor unit of the air conditioner as the circle, the maximum angle covered by the horizontal rotation of the air deflector as the center angle, and the maximum air supply distance of the air conditioner as the radius. For the air field of the air-conditioned room, the effective detection area can reflect the direct adjustment effect of the air conditioner to the greatest extent;

Limit the two-dimensional plane of the air-conditioned room as the effective detection area;

Divide the effective detection area into multiple sub-areas. In this embodiment, the sub-regions are unequally divided, the area of the sub-region closer to the air conditioner is smaller, and the area of the sub-region farther away from the air conditioner is larger. Record the boundary coordinates of each subregion.

The infrared sensor installed on the indoor unit of the air conditioner scans multiple sub-areas one by one in the effective detection area to determine whether there is a person in each sub-area. Preferably, within the first valid timing period after the air conditioner is turned on, the infrared sensor scans all sub-areas one by one. Since the same user cannot be in two sub-areas at the same time within one valid timing period, it can be accurately determined Calculate the current number of users and assign user IDs to them for follow-up tracking and identification of new users entering the effective detection area.

If there is a person in the corresponding sub-area, the projection element is controlled to project to the user in the corresponding sub-area with the light color corresponding to the temperature and cold feeling parameter.

At the same time, if there is a person in the corresponding sub-area, the original image of the effective detection area is generated when the boundary coordinates of the sub-area are recorded. A valid detection mark is added to the corresponding sub-area position of the original image of the valid detection area to generate a display image of the valid detection area. Wherein, the effective detection mark and the original image of the effective detection area have different color parameters, such as different hue values or different RGB values.

Detect the user's temperature and cold sensation parameters in the sub-area with the effective detection mark, and further display the control in the next step. The color parameter of the valid detection mark is preferably replaced with the same color parameter in the display mode corresponding to the warm and cold feeling parameter.

In the daily use of the air conditioner, the area directly covered by the supply air has the most significant adjustment effect. In order to reflect the connection between air supply, air conditioning effect, and specific user comfort during the display process. As a preferred embodiment of the display control method shown in FIG. 2, the following steps are also included:

Generates the original image of the air supply area with the same size as the effective detection area.

Taking the angle between the horizontal rotation positions of the current air deflector as the central angle, and the maximum air supply distance of the air conditioner as the radius, the image of the effective air supply area is formed. The current horizontal rotation position of the wind deflector can be detected by a proximity sensor or by an output signal of a stepper motor. The image of the effective air supply area has different color parameters than the original image of the air supply area. The original image of the air supply area and the effective air supply area image are synthesized to form a display image of the air supply area.

Furthermore, the display image of the effective detection area and the display image of the air supply area have different color parameters. The display image of the effective detection area and the display image of the air supply area are synthesized and displayed. Users can intuitively see the difference in comfort changes within the air supply area and outside the air supply area, which better reflects the control effect of the air conditioner.

Preferably, the above-mentioned method for controlling the projection display of the sense of warmth and cold is executed by a controller independent of the control chip of the indoor unit of the air conditioner. The independent display screen displays the composite display effect of the original image and the warm and cold image, the composite display effect of the effective detection area display image and the air supply area display image. If more than one fan is installed in the indoor unit of the air conditioner, the fan speed is also displayed on a separate display.
