Fig. 1 is a schematic diagram of a method for controlling an air conditioner according to an embodiment of the present disclosure; as shown in fig. 1, an embodiment of the present disclosure provides a method for controlling an air conditioner, including:
and S11, the air conditioner obtains scene reference information corresponding to the target scene collected by the millimeter wave radar.
And S12, the air conditioner determines a target load adjustment scheme of the air conditioner according to the scene reference information.
And S13, the air conditioner controls the air conditioner to execute the target load adjustment scheme.
In the scheme, the air conditioner can acquire scene reference information corresponding to a target scene through the associated millimeter wave radar. Here, the millimeter wave radar is a radar operating in the millimeter wave band for detection. Millimeter-wave radar has some of the advantages of both microwave and photoelectric radar because the wavelength of millimeter-wave waves is intermediate between microwave and centimeter waves. The millimeter wave radar can carry out position detection, people number detection, breathing/heartbeat detection, track tracking, volume measurement and calculation and the like in the environment where the millimeter wave radar is located so as to accurately identify the micro motion, the space volume, the activity intensity and the human posture of a user, information acquired by the millimeter wave radar is not influenced by photo-thermal and the like, the privacy problem is not involved, and compared with the existing camera image acquisition and infrared image acquisition modes, the reliability is higher, and the privacy protection performance is better. Specifically, the millimeter wave radar associated with the air conditioner may be connected to the air conditioner in a wired or wireless manner, and may be disposed in an environment where the air conditioner is located. The wireless connection method is not limited to bluetooth connection, WIFI connection, and the like. In an optimized scheme, the millimeter wave radar can be embedded in the air conditioner associated with the millimeter wave radar to collect various information in the environment where the air conditioner is located. In this embodiment, there may be a variety of scenarios within the environment in which the air conditioner is located. As an example, the environment in which the air conditioner is located may include a home scene and a business scene. A commercial scene herein may refer to a scene for business office. Specifically, the scene reference information corresponding to each of the different scenes may be stored in advance in the air conditioner. For example, if the target scene is a home scene, the scene reference information corresponding to the home scene may include one or more of identity information of the user, activity intensity of the user, and posture information of the user. If the target scene is a commercial scene, the scene reference information corresponding to the commercial scene may be the number of users in a unit area. In this way, after the air conditioner determines the target scene, the scene reference information corresponding to the target scene can be collected through the millimeter wave radar. Further, the cooling/heating requirements of the users in the scene can be judged by combining the acquired scene reference information, so that a target load adjustment scheme suitable for the cooling/heating requirements of the users in the target scene is determined, and the air conditioner is controlled to execute the target load adjustment scheme.
By adopting the method for controlling the air conditioner, the scene reference information corresponding to the target scene can be collected through the millimeter wave radar associated with the air conditioner, and the target load adjustment scheme of the air conditioner is determined by combining the obtained scene reference information, so that the air conditioner is controlled to execute the target load adjustment scheme. Therefore, the refrigerating capacity requirement of the user in the current scene can be determined by combining the scene reference information acquired by the millimeter wave radar, and the target load adjustment scheme meeting the refrigerating capacity requirement is determined, so that the air conditioner load is more intelligently controlled under the condition that the air conditioner is controlled to execute the target load adjustment scheme, and the load adjustment requirement of the user in the scene is met.
Optionally, at S12, the determining, by the air conditioner according to the scene reference information, a target load adjustment scheme of the air conditioner includes:
in case that the user's identity information is a child, the air conditioner determines that its target load adjustment scheme is a reduced load scheme. In case that the user's identity information is an adult, the air conditioner determines that its target load adjustment scheme is an increase load scheme or a maintenance load scheme.
In the scheme, if the target scene is a home scene and the scene reference information is identity information of a user, identity recognition of the user can be carried out by combining a breathing/heartbeat or volume measurement result acquired by the millimeter wave radar, and under the condition that the identity information of the user is a child, the target load adjustment scheme is determined to be a load reduction scheme, so that the refrigerating capacity output by the air conditioner is reduced in the process that the air conditioner operates according to the load reduction scheme, the discomfort brought to the child with weak immunity due to overhigh refrigerating capacity of the air conditioner is relieved, and under the condition that the identity information of the user is an adult, the target load adjustment scheme of the air conditioner is determined to be a load improvement scheme or a load maintenance scheme. Here, the set load may be stored in the air conditioner in advance, and the set load may be determined in combination with a historical operating condition of the air conditioner or may be determined in advance in combination with an energy saving standard of the air conditioner. Specifically, if the output load of the current air conditioner is higher than the set load, the target load adjustment scheme of the air conditioner may be determined to be the maintenance load scheme. If the current output load of the air conditioner is not higher than the set load, the target load adjustment scheme of the air conditioner can be determined to be the load improvement scheme. Here, the load increase scheme may include any manner capable of increasing an output load of the air conditioner, for example, increasing an operation frequency of the compressor, etc. The load reduction scheme may include any manner capable of reducing the output load of the air conditioner, such as reducing the operating frequency of the compressor, etc. Therefore, the millimeter wave radar can be combined to identify the accurate user identity information, the intelligent control is carried out on the air conditioner output load in the scene by combining the user identity information, the refrigerating capacity of the air conditioner is effectively controlled, and more comfortable environment experience is provided for the user.
Optionally, at S12, the determining, by the air conditioner according to the scene reference information, a target load adjustment scheme of the air conditioner includes:
under the condition that the activity severity of the user is low, the air conditioner determines that the target load adjustment scheme is that the air conditioner is operated according to the first target evaporation temperature; under the condition that the activity intensity of the user is in medium intensity, the air conditioner determines that the target load adjustment scheme is that the air conditioner operates according to a second target evaporation temperature; and under the condition that the activity intensity of the user is high intensity, the air conditioner determines that the target load adjustment scheme is to operate the air conditioner according to the third target evaporation temperature.
In the scheme, if the target scene is a family scene and the scene reference information is the activity severity of the user, the target load adjustment scheme of the air conditioner can be determined by combining the activity severity of the user acquired by the millimeter wave radar. Specifically, a plurality of severity levels may be stored in advance in the air conditioner to analyze the activity severity of the user collected by the millimeter wave radar. As an example, if the user is walking normally and/or has a heartbeat of 60-95 times/minute, the activity intensity of the user is determined to be at a low intensity. If the user is jogging, exercising, and/or having a heartbeat in the range of 95-135 beats/minute, the user's activity intensity is determined to be at a medium intensity. If the user is running, skipping a rope, and/or jumping 175 times/minute on the treadmill, the user's activity intensity is determined to be at a high intensity. Further, a target load adjustment scheme for the air conditioner may be determined in conjunction with the determined level at which the user's dramatic activity is. Specifically, a target evaporation temperature of the air conditioner may be determined, and it is understood that the stronger the activity intensity of the user, and accordingly, the greater the cooling capacity required for the air conditioner, the lower the evaporation temperature of the heat exchanger. Therefore, the air conditioner is operated according to the first target evaporation temperature under the condition that the activity severity of the user is low; under the condition that the activity intensity of the user is in medium intensity, the air conditioner is operated according to a second target evaporation temperature; and operating the air conditioner at the third target evaporation temperature under the condition that the activity intensity of the user is high. Here, the first target evaporation temperature is higher than the second target evaporation temperature, which is higher than the third target evaporation temperature. As an example, the first evaporation temperature may be 2 deg.C, the second evaporation temperature may be-2 deg.C, and the third evaporation temperature may be-5 deg.C. Therefore, the activity severity of the user can be accurately identified by combining the millimeter wave radar, the output load of the air conditioner in the scene is intelligently controlled by combining the activity severity of the user, the refrigerating capacity of the air conditioner is effectively controlled, and more comfortable environment experience is provided for the user.
Preferably, the target evaporation temperature of the heat exchanger can be determined by combining the activity severity of the user and the identity information of the user. It can be understood that the cooling capacity required by the old/young people is smaller than that of the adult, and the air conditioner can be operated according to the fourth target evaporation temperature under the condition that the activity severity of the user is low and the identity information of the user is the young or the old; the air conditioner is operated according to a fifth target evaporation temperature under the conditions that the activity severity of the user is in a medium intensity and the identity information of the user is a child or an old person; and when the activity intensity of the user is high and the identity information of the user is a child or an old person, operating the air conditioner according to a sixth target evaporation temperature. Here, the fourth target evaporation temperature is higher than the first target evaporation temperature, the fifth target evaporation temperature is higher than the second target evaporation temperature, and the sixth target evaporation temperature is higher than the third target evaporation temperature. As an example, the fourth evaporation temperature may be 5 deg.C, the second evaporation temperature may be 2 deg.C, and the third evaporation temperature may be-2 deg.C. Therefore, the output load of the air conditioner in the scene can be intelligently controlled by combining the identity information of the user detected by the millimeter wave radar and the activity intensity of the user, and the environment experience of the user is improved.
Optionally, at S12, the determining, by the air conditioner according to the scene reference information, a target load adjustment scheme of the air conditioner includes:
under the condition that the posture information of the user indicates that the user is in a sleeping or static state, the air conditioner determines that the target load adjustment scheme is a load reduction scheme; and under the condition that the posture information of the user indicates that the user is in a motion state, the target load adjustment scheme determined by the air conditioner is a load increasing scheme.
In the scheme, if the target scene is a home scene and the scene reference information is the posture information of the user, the posture information of the user can be identified by combining the millimeter wave radar, and the target load adjustment scheme is determined to be the load reduction scheme under the condition that the posture information of the user indicates that the user is in a sleep or static state, so that the refrigerating capacity output by the air conditioner is reduced in the process that the air conditioner operates according to the load reduction scheme, the discomfort brought to the user in the sleep or static state due to the overhigh refrigerating capacity of the air conditioner is relieved, and the target load adjustment scheme of the air conditioner is determined to be the load improvement scheme under the condition that the posture information of the user indicates that the user is in a motion state. Here, the load increase scheme may include any manner capable of increasing an output load of the air conditioner, for example, increasing an operation frequency of the compressor, etc. The load reduction scheme may include any manner capable of reducing the output load of the air conditioner, such as reducing the operating frequency of the compressor, etc. Therefore, the millimeter wave radar can be combined to identify the accurate user posture information, the intelligent control is carried out on the air conditioner output load in the scene by combining the posture information of the user, the refrigerating capacity of the air conditioner is effectively controlled, and more comfortable environment experience is provided for the user.
Optionally, at S12, the determining, by the air conditioner according to the scene reference information, a target load adjustment scheme of the air conditioner includes:
under the condition that the number of users in a unit area is lower than a first threshold value, the air conditioner determines that a target load adjustment scheme is a load reduction scheme; in the case where the number of users per unit area is higher than the second threshold, the air conditioner determines the target load adjustment scheme to be the increased load scheme.
In the scheme, if the target scene is a commercial scene and the scene reference information is the number of users in a unit area, the number of users in the unit area can be identified by combining the millimeter wave radar, and under the condition that the number of users in the unit area is lower than a first threshold value, the target load adjustment scheme is determined to be a load reduction scheme, so that the refrigerating capacity output by the air conditioner is reduced in the process that the air conditioner operates according to the load reduction scheme, the refrigerating capacity output of the air conditioner can be reasonably controlled under the condition that the number of users in the environment where the air conditioner is located is small, and the energy loss is reduced. And determining the target load adjustment scheme of the air conditioner as the load improvement scheme under the condition that the number of users in the unit area is higher than a second threshold value. Therefore, the refrigerating capacity output by the air conditioner can be improved under the condition of more people in the environment where the air conditioner is located, and the refrigerating requirement of users in the environment where the air conditioner is located is met. Specifically, the first threshold value and the second threshold value may be stored in advance in the air conditioner. As an example, the first threshold may be 0.3 people/square and the second threshold may be 1 person/square. Like this, can combine the comparatively accurate user number in the unit area of millimeter wave radar discernment to combine the user number in the unit area to carry out intelligent control to the air conditioner output load in the scene, with under the population density of difference, realize rationalization utilization to the refrigeration resource of air conditioner when satisfying user's environmental requirement.
Fig. 2 is a schematic diagram of another method for controlling an air conditioner according to an embodiment of the present disclosure; with reference to fig. 2, an embodiment of the present disclosure further provides a method for controlling an air conditioner, including:
and S21, the air conditioner determines the target scene of the room in which the air conditioner is positioned.

And S24, the air conditioner controls the air conditioner to execute the target load adjustment scheme.
In the scheme, before scene reference information corresponding to a target scene collected by the millimeter wave radar is obtained, the target scene of the room where the air conditioner is located needs to be determined. Specifically, the target scene of the room in which the air conditioner is located can be determined in various ways. As an example, if the room where the air conditioner is located is unmanned every week for 1-2 days, the target scene of the room where the air conditioner is located is determined to be a commercial scene, otherwise, the target scene is determined to be a home scene. In another example, if a user with a lying posture exists in the room where the air conditioner is located at night, it is determined that the target scene in the room where the air conditioner is located is a home scene, and otherwise, the target scene is a commercial scene. By the scheme, the target scene can be judged according to the scene judgment reference prestored in the air conditioner, and the accuracy of the scene judgment result is effectively guaranteed.
FIG. 3 is a schematic diagram of a method for determining a target scene according to an embodiment of the present disclosure; referring to fig. 3, S41, the target scene of the room where the air conditioner is located may be determined by:
if the user is in the sleep state within the first preset time period and the sleep state lasts for the preset time length, the air conditioner determines that the indoor target scene where the user is located is a family scene. If the population density of the indoor space where the air conditioner is located in the second preset time period is larger than the third threshold value, and the population density of the indoor space where the air conditioner is located in the third preset time period is lower than the fourth threshold value, the air conditioner determines that the target scene of the indoor space where the air conditioner is located is a commercial scene.
In a preferred embodiment, the pre-stored scene decision criteria in the air conditioner may include: if the user is in the sleep state within the first preset time period and the sleep state lasts for the preset time length, the air conditioner determines that the indoor target scene where the user is located is a family scene. Here, the first preset period may be any period during the night. As an example, the first preset time period may be 9:00 late to 8:00 early. The preset time period may be 6 hours or more. The pre-stored scene determination criteria of the air conditioner may further include: if the population density of the indoor space where the air conditioner is located in the second preset time period is larger than the third threshold value, and the population density of the indoor space where the air conditioner is located in the third preset time period is lower than the fourth threshold value, the air conditioner determines that the target scene of the indoor space where the air conditioner is located is a commercial scene. Here, the second preset time period may be any time period during the day. For example, the second preset time period may be 9:00 a.m. to 9:00 a.m. The third threshold may be 0.5 persons/square, the third preset time period may be 9:00 late to 9:00 early, and the fourth threshold may be 0.1 persons/square. Therefore, the target scene of the indoor where the air conditioner is located can be determined more accurately by combining the prestored scene judgment reference.
Fig. 4 is a schematic diagram of a method for pushing warning information according to an embodiment of the present disclosure; as shown in fig. 4, an embodiment of the present disclosure further provides a method for pushing early warning information, including:
and S41, the air conditioner obtains scene reference information corresponding to the target scene collected by the millimeter wave radar.
And S42, the air conditioner tracks the physical signs of the user in the stationary state in the room where the air conditioner is located to obtain the physical sign tracking result.
And S43, when the sign tracking result shows that the sign of the user does not reach the standard, the air conditioner pushes early warning information to the target user.
In the scheme, after the air conditioner obtains the scene reference information corresponding to the target scene collected by the millimeter wave radar, sign tracking can be performed on the user in the indoor static state according to the scene reference information, so that a sign tracking result can be obtained. Here, the scene reference information may include a heart rate and/or a breathing rate of the user, so that the comparison is performed in combination with the pre-stored physical sign condition of the user in the still state in the air conditioner to determine whether the user is a still user. Further, after the user is determined to be in a static state, sign tracking can be performed on the user. Here, the physical sign tracking is to acquire the heart rate and the breathing condition of the user in real time through a millimeter wave radar. The sign tracking result is the real-time heart rate and respiration condition of the user. Therefore, whether the physical sign of the user reaches the standard or not can be determined by combining the physical sign standard stored in the air conditioner in advance. For example, a respiration reference range and/or a heart rate reference range of the user in a stationary state may be previously stored in the air conditioner. And when the sign tracking result is out of the reference range, determining that the sign of the user does not reach the standard, and pushing early warning information to the target user in time. Here, the target user may be a user whose physical sign does not reach the standard, and the target user may also be an emergency contact of the user whose physical sign does not reach the standard. In this way, the users in the scene can be monitored in real time through the radar millimeter waves, and early warning intervention is performed when abnormal conditions exist.
Optionally, the air conditioner may further perform intelligent load regulation and control by combining the indoor environment parameters and the scene reference information acquired by the millimeter wave radar.
Specifically, if the difference between the indoor collection temperature and the indoor set temperature is less than or equal to 2 ℃, the number of people per unit area detected by the millimeter wave radar is less than 0.1 person/1 square, and the sport intensity of the user is low, the air conditioner can be controlled to execute the load reduction scheme. Here, the intelligent load control can be realized by reducing the frequency of the compressor or increasing the superheat degree, and the energy-saving control of the air conditioner can be realized while the refrigerant flow of the indoor unit is effectively reduced.
In another example, if the air conditioner includes two compressors, in the case of controlling the air conditioner to perform the load reduction scheme, the operation of the compressor having a smaller input power is preferentially controlled, and the operation of the compressor having a larger input power is controlled to be stopped. In an optimization scheme, under the condition of controlling the air conditioner to execute a load reduction scheme, the rotating speed of a fan of an indoor unit can be adjusted to be a low level, so that the load can be dynamically adjusted according to the cold and hot demands of users, and the intelligent level of the control process is improved.

By adopting the device for controlling the air conditioner, the scene reference information corresponding to the target scene can be collected through the millimeter wave radar associated with the air conditioner, and the target load adjustment scheme of the air conditioner is determined by combining the obtained scene reference information, so that the air conditioner is controlled to execute the target load adjustment scheme. Therefore, the refrigerating capacity requirement of the user in the current scene can be determined by combining the scene reference information acquired by the millimeter wave radar, and the target load adjustment scheme meeting the refrigerating capacity requirement is determined, so that the air conditioner load is more intelligently controlled under the condition that the air conditioner is controlled to execute the target load adjustment scheme, and the load adjustment requirement of the user in the scene is met.
