detailed description

In order to have a more detailed understanding of the features and technical content of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The attached drawings are for reference and explanation purposes only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a number of details are used to provide a sufficient understanding of the disclosed embodiments. However, without these details, one or more embodiments can still be implemented. In other cases, in order to simplify the drawings, well-known structures and devices may be simply shown.

Fig. 1 is a schematic flowchart of a method for controlling an air conditioner provided by an embodiment of the present disclosure.

In this embodiment, the method for controlling the air conditioner includes:

Step S101: Determine the emotional state of the personnel.

Among them, the emotional state of personnel can include: excitement, grief, fear, surprise, acceptance, ecstasy, anger, hatred, disgust, boredom, sadness, hesitation, peace, etc. The determination of the emotional state of a person refers to the result that the controller of the air conditioner can determine the emotional state of the person, and does not limit the process of determining the emotional state of the person, or the process of identifying the emotional state of the person. Optionally, the emotional state of the personnel is obtained through image recognition technology. The recognition process can be performed on the controller of the air conditioner or outside the controller of the air conditioner. For example, the emotional state of the personnel is recognized on the cloud server, and then the recognized personnel The emotional state is sent to the controller of the air conditioner, and the controller receives the identified emotional state of the person to determine the emotional state of the person. Optionally, it may also include determining the emotional state of the person through the pitch, rate of speech, and body temperature of the person's voice. For example: when the voice of the person is low, speaking speed is slow, and the body temperature is stable, the mood of the person can be determined to be calm; when the voice of the person is high, speaking speed and body temperature are high, it can be determined that the person is excited or angry. Optionally, the emotional state of the person can also be determined by the physiological characteristics of the person. For example, when a person is emotionally stressed, breathing speeds up, heartbeat speeds up, blood pressure rises, blood sugar rises, blood oxygen increases, adrenal and thyroid hormones Increased secretion; when people are frightened, the heartbeat slows down, breathing is sometimes paused, small blood vessels in the face contract, face pale, cold sweats, dry mouth, etc.; only as far as the respiratory system is concerned, when the mood changes, the frequency, depth, and depth of breathing The speed, uniformity, etc. will change; the breathing rate is 9 times per minute when negatively sad, 17 times per minute when happy, 40 times per minute when angry, and 64 times per minute when fearful. During emotional response, brain electricity and skin electricity also change with changes in emotions.

Step S102: Obtain a temperature adjustment process matching the emotional state of the personnel.

Among them, the temperature adjustment process refers to the process in which the air conditioner adjusts the ambient temperature from the real-time ambient temperature to the set ambient temperature. Optionally, the temperature adjustment process includes a set temperature that changes with time and a set wind speed that changes with time. The set temperature can be the coil temperature of the indoor unit of the air conditioner, or it can be the air outlet temperature of the air outlet of the indoor unit of the air conditioner. The greater the difference between the set temperature and the real-time ambient temperature, the higher the rate of heat exchange between the air conditioner indoor unit and the room; the greater the set wind speed, the higher the rate of heat exchange between the air conditioner indoor unit and the room, that is, The fixed temperature and set wind speed can affect the rate of heat exchange between the indoor unit of the air conditioner and the room, and the rate of heat exchange between the indoor unit of the air conditioner and the room can affect the rate of change of the indoor environment temperature. The greater the heat exchange rate, the faster the indoor environment temperature changes. ; The smaller the rate of heat exchange between the indoor unit of the air conditioner and the room, the slower the change in indoor ambient temperature. Therefore, the set temperature and set wind speed can determine the rate of change of the indoor ambient temperature. Obtain the temperature adjustment process, that is, obtain one or more set temperatures and one or more set wind speeds.

Step S103: Control the operation of the air conditioner according to the temperature adjustment process.

In some application scenarios, the real-time ambient temperature is 30°C and the set ambient temperature is 25°C. When the mood of the personnel is different, the time required for the indoor ambient temperature to change from the real-time ambient temperature to the set ambient temperature is different.

In some embodiments, determining the emotional state of the person includes: determining that the person is in a state of depression; or, determining that the person is in an emotionally calm state; or, determining that the person is in a state of intense emotion. The emotional state is divided into three types, which simplifies the model of the program, and makes the program easy to implement on the basis that the temperature adjustment process is a dynamic process. Among them, the state of low mood may include: grief, sadness, hesitation, etc.; the state of intense mood may include: excitement, fear, surprise, ecstasy, hatred, disgust, boredom, etc.; the state of emotional peace may include: acceptance, peace, etc.

Fig. 2 is a schematic flowchart of a temperature adjustment process provided by an embodiment of the present disclosure.

In this embodiment, obtaining a temperature adjustment process matching the emotional state of the person includes:

Step S201: When the person is in a state of depression, the set temperature is increased by the first temperature, and the set wind speed is decreased by the first speed.

Wherein, the first temperature may be any one of 1°C, 2°C, 3°C, and 4°C. When the fan of the indoor unit of the air conditioner is divided into several air outlets according to different speeds, the first speed is the difference between the air outlet speeds of the two air outlets, and the set wind speed is reduced by the first speed. Decrease the fixed wind speed by one, two or more gears.

Step S202, after the first time, restore the set temperature and set wind speed.

Wherein, the first time may be 5 minutes to 20 minutes, for example, the first time may be any one of 5 minutes, 10 minutes, 15 minutes, and 20 minutes. In the foregoing, the set temperature is increased by the first temperature to obtain a new set temperature. After the first time, the set temperature is restored, which means that the new set temperature is lowered by the first temperature to obtain the original set temperature; The aforementioned increase the set wind speed by the first speed to obtain a new set wind speed. After the first time, restore the set wind speed, that is, increase the new set wind speed by the first speed again to obtain the original set wind speed. .

This embodiment shows the temperature adjustment process matched by the depressed state.

Fig. 3 is a schematic flowchart of a temperature adjustment process provided by an embodiment of the present disclosure.

Step S301: When the person is in an emotionally calm state, maintain the set temperature and set wind speed.

Step S302: After the second time, the set temperature is increased by the second temperature, and the set wind speed is decreased by the second speed.

Wherein, the second time may be 5 minutes to 20 minutes, for example, the second time may be any one of 5 minutes, 10 minutes, 15 minutes, and 20 minutes. The second temperature can be any one of 1°C, 2°C, 3°C, and 4°C. When the fan of the indoor unit of the air conditioner is divided into several air outlet gears according to different speeds, the second speed is the difference between the air outlet speeds of the two air outlets, and the set wind speed is reduced by the second speed. Decrease the fixed wind speed by one, two or more gears.

The above embodiment shows the temperature adjustment process matched by the emotional calm state.

FIG. 4 is a schematic flowchart of a temperature adjustment process provided by an embodiment of the present disclosure.

Step S401: When the person is in an emotionally intense state, the set temperature is lowered by a third temperature, and the set wind speed is increased by a third speed.

Wherein, the third temperature can be any one of 1°C, 2°C, 3°C, and 4°C. When the fan of the indoor unit of the air conditioner is divided into several air outlet gears according to different speeds, the third speed is the difference between the air outlet speeds of the two air outlets, and the set wind speed is increased by the third speed. Increase the fixed wind speed by one, two or more gears.

Step S402, after the third time, restore the set temperature and set wind speed.

Wherein, the third time may be 5 min to 20 min, for example, the third time may be any one of 5 min, 10 min, 15 min, and 20 min. In the foregoing, the set temperature is lowered by the third temperature to obtain a new set temperature. After the third time, the set temperature is restored, that is, the new set temperature is increased by the third temperature to obtain the original set temperature; As mentioned above, increase the set wind speed by the third speed to obtain a new set wind speed. After the third time, restore the set wind speed, which is to reduce the new set wind speed by the third speed again to obtain the original set wind speed. .

This embodiment shows the temperature adjustment process matched by the emotionally intense state.

Fig. 5 is a schematic flow chart of controlling the operation of an air conditioner according to a temperature adjustment process provided by an embodiment of the present disclosure.

In this embodiment, controlling the operation of the air conditioner according to the temperature adjustment process includes:

Step S501: Obtain a set temperature difference and a real-time ambient temperature matching the emotional state of the person.

The emotional state of personnel can be divided into three categories: low-emotional state, emotionally calm state and emotionally intense state. The set temperature that matches the emotional state of the personnel is obtained, including: when the personnel is in a low-emotion state, the first temperature difference is used as the setting Set the temperature difference. When the person is in a state of emotional calm, the second temperature difference is used as the set temperature difference; when the person is in an emotional state, the third temperature difference is used as the set temperature difference, where the first temperature difference is less than the first temperature difference. Two temperature differences, the second temperature difference is smaller than the third temperature difference. This embodiment shows a specific matching process between the mood of the person and the set temperature difference.

The real-time ambient temperature can be obtained through the temperature sensor installed on the indoor unit of the air conditioner.

Step S502: Calculate the sum/difference of the difference between the real-time ambient temperature and the set temperature, and determine the coil temperature of the indoor unit.

Step S503: Control the operation of the air conditioner according to the coil temperature.

This embodiment can adjust the temperature of the coil to a set temperature. When the set temperature changes, the temperature of the coil also changes, and the heat exchange rate between the indoor unit of the air conditioner and the indoor ambient air changes, thus realizing the control of the temperature adjustment speed. Control the operation of the air conditioner according to the coil temperature, including adjusting the operating power of the air conditioner compressor so that the real-time coil temperature of the indoor unit reaches the coil temperature.

Optionally, controlling the operation of the air conditioner according to the temperature adjustment process further includes: controlling the rotation speed of the fan of the indoor unit of the air conditioner according to the set wind speed.

In some embodiments, when the real-time ambient temperature is lower than the set ambient temperature, the sum of the real-time ambient temperature and the set temperature difference is calculated; when the real-time ambient temperature is higher than the set ambient temperature, the real-time ambient temperature and the set temperature are calculated Bad bad. When the real-time ambient temperature is lower than the set ambient temperature, the ambient temperature needs to be increased. Here the coil temperature is higher than the real-time ambient temperature, and the indoor unit releases heat into the room; when the real-time ambient temperature is higher than the set ambient temperature, the coil The temperature is lower than the real-time ambient temperature, and the indoor unit absorbs heat indoors. Therefore, this solution can be applied to the cooling process of the indoor environment and the heating process of the indoor environment.

In some embodiments, the set environmental temperature can be set by the user, and the user's emotions can be recognized through artificial intelligence technology, and the set environmental temperature can be automatically calculated according to the user's emotions. For example, after obtaining the user's emotion, the user's emotion is matched in big data to obtain the most suitable setting environment temperature.
