S102. The server executes and calculates the illumination coefficient in the room.

S103, the server executes to control the opening state of the curtain according to the operating state of the air conditioner and the light coefficient in the room.

By adopting the method for controlling the curtains provided by the embodiments of the present disclosure, by controlling the open state of the curtains, it is possible to reduce the direct sunlight entering the room in summer, reduce the burden on the indoor air conditioning and refrigeration system, and reduce the heat energy radiated through the glass in the form of infrared rays in winter. Outdoor, reduce the heating burden of the indoor air conditioner, thereby reducing the power consumption of the indoor air conditioner.

Optionally, the server executes controlling the opening state of the curtains according to the operating state of the air conditioner and the illumination coefficient in the room, including: the server executes when the air conditioner is in cooling mode and the illumination coefficient in the room is greater than or equal to the first parameter value, Control the curtains to be fully closed; or, the server executes to control the curtains to half open when the air conditioner is in cooling mode and the light coefficient in the room is less than the first parameter value and greater than or equal to the second parameter value; or, the server executes when the air conditioner is in cooling mode. Mode, when the light coefficient in the room is less than the second parameter value, control the curtains to fully open; or, the server executes when the air conditioner is in heating mode and the light coefficient in the room is greater than or equal to the third parameter value, control the curtains fully open; or, the server executes the control of half-opening the curtains when the air conditioner is in the heating mode and the light coefficient in the room is less than the third parameter value and greater than or equal to the fourth parameter value; or, the server executes when the air conditioner is in the heating mode mode, when the light factor in the room is less than the value of the fourth parameter, the curtains are controlled to be fully closed.

Wherein, the first parameter value includes a fixed empirical value, the second parameter value includes a fixed empirical value, the third parameter value includes a fixed empirical value, and the fourth parameter value includes a fixed empirical value.

In this way, the opening state of the curtains can be better controlled according to the operating state of the air conditioner and the light factor. In summer, when the indoor air conditioner is cooling, it can reduce direct sunlight into the room and reduce the burden on the indoor air conditioning and refrigeration system. In winter, the indoor air conditioner is heating. , reduce the heat energy radiated to the outside through the glass in the form of infrared rays, reduce the heating burden of the indoor air conditioner, thereby reducing the power consumption of the indoor air conditioner.

The unit of the illumination coefficient CLQj·τ in the room is watts, and CLQj·τ depends on many factors. In terms of solar radiation, the radiation intensity and incident angle are different according to latitude, month, date and time. From the perspective of the window itself, CLQj·τ varies with the optical properties of the glass, whether there is a sunshade device, and the window structure (steel, wooden windows, single and double glazing). In addition, CLQj·τ is also related to the internal and external heat dissipation coefficient. In engineering, the illumination coefficient is calculated by CLQj·τ=xg*xd*Cs*Cn*An*Jj·τ, and the unit is watts.

When calculating the time, the cooling load Jj·τ formed by the total solar radiant heat passing through the unit window area is referred to as the load, and the unit is watts/square meter.

In this way, the opening state of the curtains can be controlled better and more accurately, reducing the direct sunlight entering the room in summer and reducing the burden on the indoor air conditioning and cooling system, and reducing heat energy in the form of infrared radiation through the glass to the outside in the form of infrared rays in winter, reducing the heating of the indoor air conditioner burden, thereby reducing the power consumption of indoor air conditioners.

Optionally, the effective area coefficient of the windows is obtained by matching the number of windows in the room, the corresponding orientations of the windows and the corresponding areas of the windows in the pre-stored setting information database.

Wherein, the number of windows in the room can be obtained from the number of windows in the room where the server receives input from the user.

The corresponding orientation of the window can be obtained from the corresponding orientation of the window in the room where the server receives user input. For the consideration of both user experience and accuracy, 8 directions (east, south, west, north, southeast, northeast, southwest, Northwest) to distinguish.

The corresponding area of the window may be obtained from the corresponding area of the window of the room where the server receives input from the user. Wherein, the corresponding area of the windows in the room includes: if there are multiple windows with different orientations, the server receives the corresponding area of the windows input by the user; or, if there are multiple windows with the same orientation, the server first receives each The area of the window, and then add the corresponding area of the window according to the same orientation; or, the server directly receives the window area input by the user; or, the server first receives the length and width of the window input by the user, and then calculates the obtained window the corresponding area of .

In summer, direct sunlight can be reduced into the room, and the burden on the indoor air conditioning and refrigeration system can be reduced. In winter, heat can be reduced in the form of infrared rays. The glass radiates to the outside, reducing the heating burden of the indoor air conditioner, thereby reducing the power consumption of the indoor air conditioner.

Optionally, the location correction coefficient is obtained by matching the location information of the air conditioner and the location information of the curtains in a pre-stored setting information database.

Wherein, the location information of the air conditioner includes: the location information of the air conditioner when the air conditioner is connected to the Internet of Things platform; or the location information of the air conditioner reported by the terminal device when the air conditioner is distributed through the gateway.

The location information of the curtain includes: the location information of the curtain when the curtain is connected to the Internet of Things platform; or the location information of the curtain reported by the terminal device when the curtain is connected to the network through the gateway.

Optionally, the weather intensity coefficient at the time of calculation is obtained by matching weather information in a pre-stored setting information database.

Wherein, the weather information is obtained by the server receiving the weather from the third-party weather platform in real time, including: sunny, cloudy, cloudy, and rainy.

The weather intensity coefficient when calculating the time is calculated as 1 when it is sunny, 0.8 when it is cloudy, and 0.4 when it is cloudy or rainy.

Optionally, the shading coefficient of the shading facilities inside the window is obtained by matching the shading percentage of the curtains obtained from the operating data of the curtains in the pre-stored setting information database.
