The air conditioner performs a refrigeration cycle by using a compressor, a condenser, an expansion valve, and an evaporator in the present application. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.
An embodiment of the present application provides an air conditioner, as shown in fig. 1, the air conditioner 100 includes:
a communication module 110 for establishing a connection with the intelligent control center 200, wherein the intelligent control center 200 is further connected with a panoramic camera 300 for shooting images in a room;
a controller 120 configured to:
when a first instruction sent by the intelligent control center 200 is received, controlling the air conditioner 100 to enter a sleep mode based on the first instruction;
the first instruction is sent by the intelligent control center 200 to the controller 120 when the state data of at least one user meets a first preset condition, the state data includes feature coordinates of a skeletal key point of the user in a world coordinate system and an eye state of the user, the world coordinate system is generated after the intelligent control center 200 performs three-dimensional modeling according to image data sent by the panoramic camera 300, the state data is obtained by the intelligent control center 200 from the image data based on a preset image recognition algorithm, and the first preset condition includes: the characteristic coordinates are matched with a target plane which is marked in the world coordinate system by the user in advance, the first preset time length is maintained, and the eye state is the eye closing state, or the characteristic coordinates are covered, and the eye state is the eye closing state.
In this embodiment, the communication module 110 disposed in the air conditioner 100 may be an equipment component having functions of communication and data processing, and may be a WiFi module, an 2/3/4/5G module, or an NB-IoT module, and may be connected to a home lan. The communication module 110 may establish a connection with the intelligent control center 200, and the intelligent control center 200 may connect each intelligent appliance and perform corresponding data processing. The panoramic camera 300 is installed in a user room and can shoot images in the room, the panoramic camera 300 and the intelligent control center 200 can be in wired connection or wireless connection, and the panoramic camera 300 can send shot image data to the intelligent control center 200. In order to facilitate acquisition of accurate image data at night, the panoramic camera 300 has an infrared night vision function.
The intelligent control center 200 performs three-dimensional modeling according to the image data sent by the panoramic camera 300 and generates a world coordinate system, specifically, the intelligent control center 200 splices the image data and generates a three-dimensional digital map, and establishes the world coordinate system according to a preset fixed position (such as a right lower corner right corner point of a doorway) in the three-dimensional digital map as an origin (0, 0, 0). The intelligent control center 200 is provided with a preset image recognition algorithm, and can recognize feature coordinates of the bone key points of the user in a world coordinate system and the eye state of the user from image data. The user may pre-label a target plane in the world coordinate system, which is the plane of furniture when the user sleeps, including, for example, beds, sofas, and the like. The intelligent control center 200 determines that the user enters a sleep state when the state data of at least one user meets a first preset condition, sends a first instruction to the controller 120 of the air conditioner 100 through the communication module 110, and when the controller 120 receives the first instruction, controls the air conditioner 100 to enter a sleep mode based on the first instruction, so as to ensure the comfort of indoor temperature and save electric energy.
The first preset condition includes: the characteristic coordinates are matched with a target plane which is marked by a user in a world coordinate system in advance, a first preset time is maintained, and the eye state is the eye closing state, or the characteristic coordinates are covered, and the eye state is the eye closing state, which can be specifically divided into the following two cases:
in a first case, a user is not covered by a covering object such as a quilt, characteristic coordinates of skeletal key points of the user in a world coordinate system can be detected through image data, a first preset condition is that the characteristic coordinates are matched with a target plane which is marked in the world coordinate system in advance by the user, a first preset time is maintained, and an eye state is a closed eye state, that is, if the characteristic coordinates are matched with the target plane, it is determined that the user is in a lying state, if the user is in the lying state, the first preset time is maintained, and the eye state is the closed eye state, it is determined that the user enters a sleeping state, and optionally, the first preset time can be 5 minutes.
In case two, the user is covered by the covering object, the feature coordinate cannot be detected through the image data, the first preset condition is that the feature coordinate is covered and the eye state is the eye closing state, for example, the user is covered by a quilt and is in the eye closing state, and the intelligent control center 200 may determine that the user is in the sleep state.
In addition, whether the human eyes are in an eye closing state or not can be judged according to the eye feature information in the image data; based on eye feature recognition techniques such as blink detection, two biggest differences in appearance between open eyes and closed eyes are as follows: the color distribution and the geometric shape can be used for acquiring eye characteristic information by a blink detection method based on the color distribution or a template matching method based on the geometric shape and the like, and judging whether the human eyes are in an eye closing state according to the eye characteristic information. For example, when the human eye is in the eye-closing state, the geometric shape of the human eye acquired from the image data is close to a linear shape, and the human eye can be known to be in the eye-closing state through template matching.
It is understood that, when a plurality of users exist in the room, as long as there is one user state data satisfying the first preset condition, the intelligent control center 200 determines that the user enters the sleep state, and sends a first instruction to the controller 120.
In order to accurately detect whether the user is lying down, in some embodiments of the present application, the feature coordinates include shoulder coordinates, waist-crotch coordinates, foot coordinates, and head coordinates, and the feature coordinates are matched with the target plane when the shoulder coordinates, the waist-crotch coordinates, and the foot coordinates are parallel and positioned directly above the target plane, or the feature coordinates are matched with the target plane when the head coordinates, the shoulder coordinates, and the waist-crotch coordinates are parallel and positioned directly above the target plane.
In this embodiment, whether the feature coordinates are matched with the target plane may be determined by determining the position of each feature coordinate relative to the target plane, and thus, whether the user is in a lying state may be determined. For example, if the target plane is a bed plane, coordinates of four end points of the bed plane are (0, 1,0), (1, 1,0), (0, 1, 1), (1, 1, 1), and when the shoulder coordinates, the waist-crotch coordinates, and the foot coordinates of the user are (0, 2, 0), (2, 2, 0), and (0, 2, 2), respectively, the intelligent control center 200 determines that the planes on which the shoulders, the waist-crotch, and the feet of the user are located directly above the bed plane and tend to be parallel, and determines that the user is already lying on the bed at this time, and the characteristic coordinates are matched with the target plane. Similarly, if the head coordinate, the shoulder coordinate, and the waist-crotch coordinate of the user are located directly above the target plane in parallel, the intelligent control center 200 also determines that the user is already lying in bed and the characteristic coordinates match the target plane.
In order to accurately detect whether the user is lying down, in some embodiments of the present application, the feature coordinates include shoulder coordinates, waist-crotch coordinates, foot coordinates, and head coordinates, and the feature coordinates are matched with the target plane when the shoulder coordinates and the waist-crotch coordinates are located directly above the target plane in parallel and the distance from the foot coordinates or the head coordinates to the target plane is not greater than a preset distance.
In this embodiment, whether the feature coordinates are matched with the target plane may be determined by determining the position of each feature coordinate relative to the target plane, and thus, whether the user is in a lying state may be determined. Considering that the head may be not parallel to the shoulder and the waist due to the height of the head, and the foot may be not parallel to the shoulder and the waist when placed on other objects such as a windowsill, the coordinates of the head and the foot may be allowed to be within a certain range parallel to the bed plane, for example, if the target plane is the bed plane, the shoulder coordinates of the user and the straight line formed by the waist-crotch coordinates and the bed plane exist in a parallel plane when the characteristic coordinates match with the target plane, and the head coordinates or the foot coordinates of the user are allowed to fluctuate up and down on the parallel plane, that is, the characteristic coordinates match with the target plane when the shoulder coordinates and the waist-crotch coordinates are parallel and located directly above the target plane and the distance from the foot coordinates or the head coordinates to the target plane is not more than the preset distance.
To set the air conditioner 100 to the normal mode in time when the user is in the getting-up state, in some embodiments of the present application, the controller 120 is further configured to:
when the air conditioner 100 is in the sleep mode and receives a second instruction sent by the intelligent control center 200, controlling the air conditioner 100 to be switched from the sleep mode to the normal mode based on the second instruction;
wherein, the second instruction is sent to the controller 120 by the intelligent control center 200 when the status data of all users satisfy a second preset condition, and the second preset condition includes: the characteristic coordinates are not matched with the target plane and maintain a second preset time length, and the second preset time length is longer than the first preset time length.
In this embodiment, the intelligent control center 200 sends a second instruction to the controller 120 when the status data of all users satisfy a second preset condition, and the controller 120 controls the air conditioner 100 to switch from the sleep mode to the normal mode based on the second instruction when the air conditioner 100 is in the sleep mode and receives the second instruction.
The second preset condition includes: the feature coordinates do not match the target plane and remain for a second preset duration, for example, when the shoulders, the waist and the feet of the user are not located right above the bed plane and no longer tend to be parallel beyond the second preset duration, the intelligent control center 200 determines that the user is in the getting-up state. The second preset time period may be 10 minutes.
It is understood that the air conditioner 100 is in the same room as the target plane, and the specific contents of the sleep mode and the normal mode of the air conditioner 100 are obvious to those skilled in the art and will not be described herein.
In order to further improve the user experience, in some embodiments of the present application, the user may set priorities for different users in the room, and when a plurality of users exist in the room and it is detected that the user has set priorities for different users, the intelligent control center 200 sends the first instruction or the second instruction to the controller 120 according to the status data of the user with the highest priority among the users.
By applying the above technical solution, the air conditioner includes a communication module and a controller configured to: when a first instruction sent by an intelligent control center is received, controlling the air conditioner to enter a sleep mode based on the first instruction; the first instruction is sent by the intelligent control center to the controller when state data of at least one user meet a first preset condition, the state data comprise characteristic coordinates of skeletal key points of the user in a world coordinate system and eye states of the user, the world coordinate system is generated after the intelligent control center conducts three-dimensional modeling according to image data sent by the panoramic camera, the state data are acquired by the intelligent control center from the image data based on a preset image recognition algorithm, and the first preset condition comprises: the characteristic coordinates are matched with a target plane which is marked in a world coordinate system by a user in advance, the first preset time is maintained, the eye state is in the eye closing state, or the characteristic coordinates are covered, the eye state is in the eye closing state, so that the user does not need to wear wearable equipment, the sleep mode is automatically switched, and the user experience is improved.
