The air conditioner control method of the present invention is applied to an air conditioner, and preferably, a processor and various sensors, such as a temperature sensor, an infrared sensor, an image sensor, etc., are provided in an indoor unit of the air conditioner, and the air conditioner can receive a control signal input by a remote controller, etc. The air conditioner control method of the present invention may be implemented by a software program running on a processor of the air conditioner. The air conditioner comprises an indoor unit and an outdoor unit, wherein a processor such as a singlechip, a DSP and the like with logical operation capability is arranged in a shell of the indoor unit, and a computer readable storage medium is a medium for storing a software program on the air conditioner, such as a nonvolatile memory.
The embodiment of the air conditioner control method comprises the following steps:
the present embodiment adjusts the operation parameters of the air conditioner by collecting the change of the indoor environment temperature and the human body thermal sensation value of the indoor person, for example, adjusting the set temperature of the air conditioner, the wind direction of the blowing wind, the wind speed, and the like. In this embodiment, the indoor ambient temperature who gathers can be the temperature value of indoor wall, also can be the temperature value of window, door plant, for example sets up infrared ray sensor on the air conditioner, through adjusting infrared ray sensor's angle, is just to indoor wall, door plant or window with infrared ray sensor's infrared emitter to gather the temperature value of wall, door plant or window.
Of course, the air conditioner may also collect the indoor air temperature as the indoor ambient temperature, or collect the temperature values of two or more of the wall, door panel, window and air at the same time, and use the average value of the collected temperature values of two or more objects as the indoor ambient temperature. Also, the collected wall temperature may also be a temperature value for a multi-sided wall, while the collected window temperature may be a temperature value for a number of different windows.
The air conditioner is also provided with an infrared sensor for detecting the area where indoor personnel are located and detecting the heat radiated by the human body, and the cold and heat sensing value of the human body, namely the PMV value, is calculated according to the heat radiated by the human body. The method for calculating the cold and hot feeling values can be realized by adopting various conventional calculation methods, so the invention is not limited to the specific calculation method, and the specific calculation method is not described herein again.
Generally, the result of the human body thermal sensation value technique is between-3 and +3, and the human body thermal sensation value is divided into a plurality of regions according to different values, as shown in the following table.
| PMV value | [-3,-2] | (-2,-1] | (-1，+1) | [+1,+2) | [+2,+3] |
| Interval(s) | A | B | C | D | E |
The PMV value is between-3 and-2 and is an A area, the human body feels cold, the PMV value is between-2 and-1 and is a B area, the human body feels cold, the PMV value is between-1 and +1 and is a C area, the human body feels comfortable, the PMV value is between +1 and +2 and is a D area, the human body feels warm, the PMV value is between +2 and +3 and is an E area, and the human body feels hot.
In this embodiment, it is necessary to determine the adjustment of the operating parameters of the air conditioner according to the change of the indoor ambient temperature and the change of the thermal sensation of the indoor personnel.
If the indoor personnel have only one person, the human body cold and heat feeling value of the person can be directly used as the human body cold and heat feeling value of the indoor personnel, if the indoor personnel have a plurality of persons, such as two persons or three persons, the cold and heat feeling values of the indoor personnel can be respectively calculated, and the average value of the cold and heat feeling values of the plurality of persons is used as the human body cold and heat feeling value of the indoor personnel for judging the change of the human body cold and heat feeling value. Or, the human body cold and heat feeling values of a plurality of indoor persons are determined, and the human body cold and heat feeling value of the person with the lowest human body cold and heat feeling value is selected as the human body cold and heat feeling value of the indoor person for judging the change of the human body cold and heat feeling value.
For the better temperature of adjusting the air-conditioner air-blowing, a preset temperature value is set in this embodiment, and this preset temperature value is used for comparing with the actual set temperature value of the air-conditioner, thereby adjusting the set temperature value of the air-conditioner according to different conditions. For example, the preset temperature value may be 26 ℃ or 27 ℃, for example, if the indoor person is a first type of person, such as a middle-aged person or a young person, the preset temperature value is a first preset temperature value, i.e., 26 ℃, and if the indoor person is a second type of person, such as an old person or a child, the preset temperature value is a second preset temperature value, i.e., 27 ℃. Therefore, the preset temperature value is lower than that of the second type of personnel for the first type of personnel, and the temperature value of the air blown out by the air conditioner can be adjusted according to different personnel types.
In order to determine whether the current indoor person is the first type person or the second type person, the determination may be made by receiving information input by the user, for example, setting a key on a remote controller, and sending information of the type of the indoor person by the user through the remote controller, such as whether the indoor person is a young or middle aged person, a child, or the like. Or the air conditioner is provided with an image sensor, images of indoor people are shot through the image sensor, the shot images are subjected to image analysis, and whether the indoor people are first-class people or second-class people is judged. For example, the image feature information of the middle-aged and young people and the image feature information of the old and the young children are stored in the processor in advance, and the currently shot image is obtained and compared with the pre-stored feature information, so that whether the person in the currently shot image is the middle-aged or the old and the young children is determined.
Or the air conditioner determines whether the indoor people are young or middle-aged people or old people and children according to the body temperature characteristics of the indoor people detected by the infrared sensor, and the body temperature characteristics of different people are different, for example, the body temperature of the old people is moderate in middle-aged people, the body temperature of the old people is relatively low, and the body temperature of the children is relatively high, so that whether the indoor people are young or middle-aged people or old people and children can be determined according to the body temperature characteristics of the indoor people.
The following describes the air conditioning control method according to the present embodiment with reference to fig. 1 to 3. First, step S1 is executed, and the air conditioner enters a sleep mode. For example, the user sends a control signal to the processor of the air conditioner through the remote controller, for example, sends the control signal in the form of an infrared signal, so that the air conditioner enters the sleep mode.
Then, step S2 is executed to acquire the indoor ambient temperature. Preferably, the indoor unit of the air conditioner is provided with a plurality of sensors, such as an infrared sensor or a thermocouple, for detecting the indoor ambient temperature at which the indoor unit of the air conditioner is located. In this embodiment, the indoor ambient temperature may be a wall temperature value, a door panel temperature value, a window temperature value, an indoor air temperature value, or the like. Preferably, the present embodiment uses a surface temperature value of a wall opposite to the indoor unit of the air conditioner as the indoor ambient temperature. Of course, in practical applications, the temperature values of two or more of the walls, the door panels, or the windows and the air may be used for comprehensive calculation, such as calculating the average value, as the indoor environment temperature.
Next, step S3 is executed to acquire information on changes in the indoor ambient temperature and information on changes in the human thermal sensation of the indoor person. After the indoor environment temperature is obtained, the numerical value of the indoor environment temperature can be continuously obtained, so that the change information of the indoor environment temperature can be calculated. Preferably, the air conditioner may collect the indoor ambient temperature once every predetermined time, such as every 30 seconds or every 1 minute. The change information is a trend change of the indoor environment temperature in an increasing direction or a trend change of the indoor environment temperature in a decreasing direction, and may be a change in which the indoor environment temperature is kept stable, that is, the indoor environment temperature does not increase or decrease.
Meanwhile, the air conditioner also collects data such as human body heat radiation and the like to calculate the human body cold and heat feeling value of the indoor personnel, and obtains the change information of the human body cold and heat feeling value of the indoor personnel by continuously calculating the human body cold and heat feeling value, for example, the human body cold and heat feeling value of the indoor personnel is calculated once every 30 seconds or every 1 minute, so that the change information of the human body cold and heat feeling value is determined according to the human body cold and heat feeling values for continuous times, for example, the human body cold and heat feeling value is increased or decreased.
Then, step S4 is executed to determine whether the indoor ambient temperature is within the preset ambient temperature range. Preferably, a preset ambient temperature range is preset, for example, the range is 24 ℃ to 29 ℃, and therefore, the upper threshold of the preset ambient temperature range is 29 ℃ and the lower threshold is 24 ℃. If the current indoor ambient temperature is between 24 ℃ and 29 ℃, the judgment result of the step S4 is yes, the step S5 is executed, whether the indoor ambient temperature is increased is further judged, and if the judgment result of the step S4 is no, the step S30 is executed.
In step S5, it is determined whether the indoor ambient temperature is increasing, that is, whether the change information of the indoor ambient temperature is increasing trend, if so, step S6 is executed, otherwise, step S14 is executed. If the change information of the indoor environment temperature is confirmed to be the rising trend, step S6 is executed to determine whether the change information of the human body thermal sensation value of the indoor personnel is the rising trend, if so, step S8 is executed, otherwise, step S7 is executed.
If it is determined that the human body thermal sensation value does not increase, i.e., the human body thermal sensation value is in a decreasing trend, step S7 is executed, the current set temperature value is not adjusted, and the current wind speed is not changed, but the wind direction is blown to an area where people in the room are avoided. Therefore, when the indoor environment temperature is increased but the human body thermal sensation value is changed and reduced, the wind direction of the blown wind is adjusted to avoid the area where the human body is located, so that the indoor personnel can be prevented from catching a cold due to the fact that the wind directly blows to the human body.
If it is confirmed in step S6 that the human body thermal sensation value is increased, step S8 is executed to further determine whether the human body thermal sensation value is increased from a preset thermal sensation value region, for example, from region C to region D or region E, or from region D to region E, if not, indicating that the human body thermal sensation value is increased from region a to another region, or from region B to another region, at which time the human body thermal sensation value is changed from a relatively cool state to a comfortable state, so step S10 is executed, and the set temperature, wind speed, and wind direction of the air conditioner are not changed.
If the judgment result of the step S8 is yes, when it indicates that the feeling of the indoor person is changed from the comfortable state to the hotter state, the method performs step S9, and judges whether the current set temperature is higher than a preset temperature value, where the set temperature value may be 26 ℃ or 27 ℃, and is determined according to the type of the indoor person. If the current temperature is higher than the preset temperature value, step S11 is executed to lower the current set temperature value to the preset temperature value and increase the wind speed to blow to the area where the human body is located, so that the indoor personnel can feel more comfortable. If the current set temperature value is not higher than the preset temperature value, step S12 is executed, the current set temperature value is not adjusted, but the wind speed is increased and the wind blows to the area where the indoor people are located.
After steps S7, S10, S11 or S12 are executed, step S13 is executed to determine whether to exit the sleep mode, for example, whether the user presses a signal to exit the sleep mode, for example, presses a button to exit the sleep mode, via the remote controller. If the sleep mode is exited, the control of the sleep mode is ended, and if the sleep mode is not exited, the operation state of the sleep mode is continued, the operation returns to the step 2, the indoor environment temperature is obtained again, and the subsequent judgment process is continued.
If it is determined in step S5 that the indoor environment temperature is not increasing, step S14 is performed, as shown in fig. 2, to determine whether the human body temperature of the indoor person is increasing, and if the human body temperature of the indoor person is increasing, step S15 is performed to further determine whether the human body temperature is increasing upward from a preset temperature range, for example, from the range C to the range D or the range E, or from the range D to the range E, and if so, indicating that the human body temperature is changing from comfortable to hot, step S16 is performed to increase the wind speed of the blowing wind without adjusting the currently set temperature value, and to blow the indoor person to the range, thereby reducing the body temperature of the indoor person.
If the determination result in step S15 is no, it indicates that the human body thermal sensation value of the indoor person is rising from the area a to the zone B or the area C, or rising from the area B to the area C, and the human body thermal sensation value of the indoor person is changing from a relatively cold state to a comfortable state, and at this time, step S17 is executed, and the current set temperature, wind direction, and wind speed are not changed.
If the determination result of step S14 is no, which indicates that the current indoor environment temperature and the human body thermal sensation value both decrease, step S18 is executed to further determine whether the human body thermal sensation value decreases from the preset thermal sensation value region downward, for example, from region C to region B or region a, or from region B to region a, and if not, that indicates that the human body thermal sensation value decreases from region E to region D or region C, or from region D to region C, and the human body sensation changes from hot to comfortable state, at this time step S19 is executed, the current set temperature value and wind speed are not changed, but the wind direction is blown to a region where indoor people are avoided, so as to avoid that the wind continuously blows to indoor people to further decrease the human body thermal sensation value of indoor people.
If the determination result of step S18 is yes, indicating that the indoor personnel is changing from a comfortable state to a cooler state, step S20 is executed to determine whether the set temperature value is lower than a preset temperature value, wherein the preset temperature value may be 27 ℃ or 26 ℃. If the temperature is lower than the preset temperature value, step S21 is executed, the current set temperature value of the air conditioner is increased to the preset temperature value, the wind speed is reduced, and the direction of the wind is adjusted to be directed to the area where the indoor people are avoided. If the determination result in the step S20 is negative, then step S22 is executed, the current set temperature value is not adjusted, and the wind speed is not changed, but the wind direction of the blown wind is blown to the area where the people in the room are avoided.
After performing steps S16, S17, S21 or S22, step S23 is performed to determine whether to exit the sleep mode, for example, whether the user presses a signal to exit the sleep mode, for example, presses a key to exit the sleep mode, through the remote controller. If the sleep mode is exited, the control of the sleep mode is ended, and if the sleep mode is not exited, the operation state of the sleep mode is continued, the operation returns to the step 2, the indoor environment temperature is obtained again, and the subsequent judgment process is continued.
In step S4, if it is determined that the current indoor environment temperature is not within the preset environment temperature range, i.e., the current indoor environment temperature is not between 24 ℃ and 29 ℃, step S30 is performed, as shown in fig. 3, it is determined whether the current indoor environment temperature is higher than a preset environment temperature upper limit threshold, e.g., higher than 29 ℃, if so, step S31 is performed, it is determined whether the human body thermal sensation value of the current indoor person is within a specific human body thermal sensation value region, e.g., within region D or region E, if it is within region D or region E, it indicates that the current indoor person feels hot, and step S33 is performed, it is determined whether the current set temperature value is higher than the preset temperature value, if so, step S34 is performed, the current set temperature value is decreased to the preset temperature value, and the wind speed is increased to blow to the region where the indoor person is located. If the result of the determination in step S33 is negative, in step S35, the current set temperature value is not changed, and the wind direction is increased to blow toward the area where the indoor people are located.
If the determination result of step S31 is no, it indicates that the human body thermal sensation value of the indoor person is in the area a, the area B, or the area C, and indicates that the current human body feels comfortable or cold, step S32 is executed, and the current set temperature, the current wind speed, and the current wind direction of the blown wind are not changed.
If the judgment result in the step S30 is no, step S36 is executed, whether the current indoor environment temperature is lower than the lower limit threshold of the preset environment temperature is further judged, that is, whether the current indoor environment temperature is lower than 24 ℃, if so, step S37 is executed, whether the current set temperature value is lower than the preset temperature value is judged, if so, step S38 is executed, the current set temperature value is increased to the preset temperature value, and the wind speed is reduced to blow to the area where the indoor personnel are located. If the determination result of step S37 is negative, step S39 is executed, and the current set temperature value, wind speed and wind direction are not changed.
If the result of the determination in step S36 is no, or if steps S32, S34, S35, S38, or S39 are executed, step S40 is executed to determine whether the user exits the sleep mode, for example, whether the user presses a signal for exiting the sleep mode, for example, presses a button for exiting the sleep mode, via the remote controller. If the sleep mode is exited, the control of the sleep mode is ended, and if the sleep mode is not exited, the operation state of the sleep mode is continued, the operation returns to the step 2, the indoor environment temperature is obtained again, and the subsequent judgment process is continued.
It should be noted that, in this embodiment, increasing the wind speed may be increasing the wind speed by one gear or increasing the wind speed to the highest gear, and if the current wind speed is already the highest gear wind speed, the current wind speed is not changed. Reducing the wind speed may be to reduce the wind speed by one gear or to the lowest gear, or to adjust to a silent gear, if the current wind speed is already the lowest gear, then the wind speed is not adjusted.
In addition, the air conditioner is provided with an infrared sensor for detecting the area where the indoor people are located, and when the wind direction is changed, the blowing wind is controlled to blow towards the area where the indoor people are located or blow towards the area where the indoor people are avoided in a left-right wind sweeping mode or a vertical wind sweeping mode. When the set temperature of the air conditioner needs to be lowered, the air conditioner can be uniformly lowered, stepped, directly lowered or non-uniformly lowered at a preset rate, and when the set temperature of the air conditioner needs to be raised, the air conditioner can be uniformly raised, stepped, directly raised or non-uniformly raised at a preset rate.
Therefore, by analyzing the change of the indoor environment temperature and the change of the human body cold and heat feeling of the indoor personnel and adjusting the operation parameters of the air conditioner, such as adjusting the set temperature value, the wind direction and the wind speed, the comfort level of the indoor personnel during sleeping can be improved, and the indoor personnel are prevented from feeling overheated or overcooled.
Meanwhile, the temperature of an indoor wall, the temperature of a door plate or the temperature of a window is adopted as the indoor environment temperature, the indoor temperature change can be more accurately reflected, and therefore the operation parameters of the air conditioner can be more accurately adjusted.
