Based on the hardware architecture of the air conditioner, the embodiment of the control method of the air conditioner is provided.
Referring to fig. 2, fig. 2 is a first embodiment of a control method of an air conditioner according to the present invention, the control method of the air conditioner including the steps of:
step S10, obtaining a target operation parameter and a target compensation value of the air conditioner, wherein the target compensation value is determined according to the historical operation time length of the air conditioner, and the historical operation time length is the operation time length of the air conditioner corresponding to the condition that the indoor environment before the air conditioner operates at this time reaches a comfortable state;
in this embodiment, a compensation value is set in the air conditioner, and the compensation value is used for compensating the current operating parameter of the air conditioner. For example, when the air conditioner is used for cooling, the air conditioner reduces the set cooling temperature, increases the rotating speed of an indoor fan, increases the operating frequency of a compressor and/or increases the opening degree of a throttling component through a compensation value; when the air conditioner heats, the air conditioner increases the set heating temperature, increases the rotating speed of the indoor fan, increases the operating frequency of the compressor and/or increases the opening of the throttling component through the compensation value. It is understood that the compensation value includes one or more of a set temperature compensation value for cooling or heating of the air conditioner, a rotation speed compensation value of the indoor fan, an operation frequency compensation value of the compressor, and an opening degree compensation value of the throttling assembly. The air conditioner can judge whether the performance of the air conditioner is reduced or not through each historical operation time length, wherein the historical operation time length refers to the operation time length of the air conditioner when the indoor temperature reaches a comfortable state before the air conditioner operates at this time. For example, the last historical operating time of the air conditioner is 10min, and the last historical operating time is 8min, at this time, it may be determined that the performance of the air conditioner is degraded, the air conditioner may determine the compensation value according to the difference between the two historical operating times, and the larger the difference between the historical operating times is, the larger the absolute value of the compensation value is. The compensation value stored in the air conditioner may be the target compensation value.
The air conditioner stores the operation duration corresponding to the comfortable environment of the indoor environment when the air conditioner operates every time, and the operation duration is the historical operation duration. The indoor environment reaching the comfortable state can be determined by detecting the cool and heat feeling value M of the user, and when M is in a preset interval, it can be determined that the indoor environment reaches the comfortable state, and the preset interval can be any number of intervals, for example, the preset interval is [ -1, 1 ].
The air conditioner is provided with an array infrared pile sensor, and the air conditioner acquires an environment background temperature image through the array infrared pile sensor. The air conditioner can obtain the cold and hot feeling value of the user according to the environment background temperature image. Specifically, according to the first law of thermodynamics, the heat dissipation amount generated by the human body is substantially equal to the heat consumed by the human body, so that the heat dissipation amount of the human body can be obtained by measuring the heat consumed by the human body, and the heat consumed by the human body can be calculated by the following formula: h ═ Φ (Tcl-Ra), where H is the heat dissipation capacity of the human body, Tcl is the temperature value of the human body surface (the temperature value of the human body surface can be determined from the ambient background temperature image), Ta is the radiation temperature value, Φ is the additional calculation coefficients, these calculation coefficients are some common calculation coefficients in the field of human body thermal comfort research, for example, considering the effective radiation area coefficient f _ eff of the ambient environment, the human body area coefficient f _ cl of the garment, Φ ═ f _ eff _ cl, at this time H ═ f _ cl (Tcl-Ta), the heat dissipation capacity H of the human body is obtained by calculating the difference between the temperature value Tcl of the human body surface and the radiation temperature Ta and combining the calculation coefficients Φ.
Of course, the values of the temperature value Tcl and the temperature value Ta may also be taken in advance according to the mapping relationship between the temperature value Tcl and the radiation temperature value Ta on the surface of the human body and the heat dissipation capacity of the human body, and the heat dissipation capacity of the human body corresponding to the temperature value Tcl and the temperature value Ta is set to form a mapping table. When the temperature value Tcl and the radiation temperature value Ta of the human body surface are obtained, the corresponding human body heat dissipation capacity can be obtained by looking up the table.
Because the value of the human body's cold and heat feeling is related to the heat consumed by the human body, and the heat consumed by the human body is equal to the heat dissipated by the human body, the state of the human body's cold and heat feeling is reflected by the magnitude of the heat dissipated by the human body, the experience test is performed on the cold and heat feelings of different users in the earlier-stage air conditioner development process, and the relational expression between the value of the human body's cold and heat feeling and the value of the heat dissipated by the different users can be obtained by the fitting formula, for example, the relational expression between the value of the cold and heat feeling state M and the value of the heat dissipated by the heat dissipated H can be expressed as follows:
M＝a0+a1H+a2H2+a3H3+…+anHn
wherein, a0, a1, a2, a3 and an are different calculation coefficient values obtained according to experiments, N is a positive value, and the value of N is determined according to a forming fitting formula between specific H and M data groups, and if N can be 4. Through the relational expression between the human body cold and heat feeling value M and the heat dissipation capacity H in the formula, after the heat dissipation capacity H of the human body is obtained through calculation, the human body cold and heat feeling value M is obtained by substituting the formula.
Of course, whether the indoor temperature reaches the comfortable temperature may be detected to determine if the indoor environment reaches the comfortable state.
And after the air conditioner operates, acquiring target operation parameters and compensation values. The target operation parameter includes at least one or more of a set temperature corresponding to cooling or heating of the air conditioner, an operation frequency of the compressor, a rotation speed of the indoor fan, and an opening degree of the throttle assembly.
Step S20, correcting the target operation parameter according to the target compensation value;
and step S30, controlling the air conditioner to operate according to the corrected target operation parameters.
After the target compensation value and the target operation parameter are determined, the air conditioner carries out compensation correction on the target operation parameter according to the compensation value, so that the air conditioner operates according to the corrected target operation parameter.
It should be noted that, when the air conditioner is turned on, the target compensation value and the target operation parameter can be determined, so that the indoor environment can reach a comfortable state as early as possible.
In the technical scheme provided by the embodiment, the target operation parameters of the air conditioner and the compensation values obtained by the historical operation durations are obtained, and the target operation parameters are corrected according to the compensation values, so that the air conditioner is controlled to operate according to the corrected target operation parameters; the air conditioner can determine whether the performance of the air conditioner is reduced or not according to the historical running time, and then determines the compensation value when the performance of the air conditioner is reduced, so that the current running parameters of the air conditioner are compensated, and the refrigerating effect or the heating effect of the air conditioner is ensured.
In an embodiment, the air conditioner may determine a plurality of compensation values in advance, may determine a target compensation value in each compensation value, and the compensation value is determined according to each historical operation time length, and stores the determined compensation value, so that the air conditioner directly corrects the operation parameter to be operated by using the stored compensation value in the subsequent operation, so as to ensure the cooling effect or the heating effect of the air conditioner. The method for determining the compensation value in advance according to each historical operating time specifically comprises the following steps:
1. determining target operation time length in each historical operation time length, wherein the environment temperature of the starting comfort function of the air conditioner corresponding to each target operation time length is the same;
the comfort function refers to a function of the air conditioner to adjust the current indoor environment to a comfortable state. The air conditioner can record the current ambient temperature when starting the comfortable function, the ambient temperature is at least one of indoor temperature and outdoor temperature, the air conditioner can start the comfortable function automatically when starting, and the opening of the comfortable function can also be set by the user. When the air conditioner operates to enable the indoor environment temperature to reach a comfortable state, the operation time of the air conditioner is recorded, and the recorded environment temperature and the operation time are correspondingly stored. The air conditioner classifies all the environment temperatures, and all the historical operation time lengths with the same environment temperature when the air conditioner is started are used as target operation time lengths.
2. Determining the maximum target operation time length and the minimum target operation time length in each target operation time length;
3. determining a first difference between the maximum target operation time length and the minimum target operation time length;
4. and determining a compensation value according to the first difference value.
After the target operation time length is determined, the air conditioner determines the maximum target operation time length and the minimum target operation time length, and then calculates a first difference value between the maximum target operation time length and the minimum target operation time length, and the difference value and the compensation value have a mapping relation, so that the compensation value can be determined according to the difference value. In addition, the mapping relationship between the difference and the compensation value is different at different environmental temperatures, and therefore, when determining the compensation value, the compensation value needs to be determined according to the environmental temperature and the difference.
The air conditioner can obtain a plurality of compensation values according to corresponding target operation time lengths under different environmental temperatures. When the air conditioner operates the comfort function currently, the ambient temperature corresponding to the currently started comfort function can be acquired, and the compensation value which is the same as the current ambient temperature is used as the target compensation value.
Of course, the air conditioner may also determine the target compensation value in real time, and when determining the target compensation value in real time, the maximum target operation time and the minimum target operation time are determined in each target operation time having the same ambient temperature corresponding to the currently opened comfort function, and other steps are consistent with the step of determining the compensation value in advance, and are not described in detail herein.
In this embodiment, the air conditioner determines the target compensation value according to each historical operating duration, so that the air conditioner compensates the operating parameter by using the target compensation value matched with the current environment, and the air conditioner compensates the operating parameter accurately.
In one embodiment, as the air conditioner is continuously used, the performance of the air conditioner is gradually decreased, and thus, the target operation time period is gradually increased, that is, it may be determined that the minimum target operation time period is a period in which the performance of the air conditioner is the best. The difference between the historical operation time length corresponding to the current operation time length of the air conditioner and the historical operation time length corresponding to the previous operation time lengths is not large, so that the current operation parameter of the air conditioner can be accurately adjusted by obtaining a compensation value according to the difference between the maximum target operation time length and the minimum target operation time length in the near term. For this, after the air conditioner determines the maximum target operation duration, it is determined whether the operation time period of the air conditioner corresponding to the maximum target operation duration is in the target time period, and an interval duration between an end time point of the target time period and a current time point is less than a preset interval duration, that is, the target time period represents a recent time period, for example, three days or a week.
And when the maximum target operation time length is determined to be in the target time period, the compensation value obtained by the maximum target operation time length and the minimum operation time length is considered to be accurate to compensate the current operation parameter. At this time, the air conditioner determines a compensation value according to a first difference between the maximum target operation time period and the minimum target operation time period.
And when the maximum target operation time length is determined not to be in the target time period, determining that the compensation value obtained by the maximum target operation time length and the minimum operation time length is inaccurate for compensating the current operation parameter. In this regard, the air conditioner selects a maximum target operation duration within the target time period, and determines a compensation value according to a second difference between the maximum operation duration and the minimum target operation duration within the target time period, thereby correcting the current operation parameter of the air conditioner according to the compensation value.
In the technical scheme provided by this embodiment, after determining the maximum target operation duration and the minimum target operation duration, the air conditioner determines whether the maximum target operation duration is within the recent time period, so as to determine a compensation value accurately according to the determination result, so that the compensated parameter of the air conditioner is relatively accurate.
In an embodiment, the air conditioner may determine the target compensation value according to the same ambient temperature corresponding to each historical operating time, where the ambient temperature is the ambient temperature corresponding to the starting comfort function of the air conditioner. Specifically, after obtaining a plurality of historical operating durations, the air conditioner determines the same historical operating durations, for example, the historical operating durations of 10min are divided into one category. The air conditioner determines the same ambient temperature corresponding to each historical operating time, selects the maximum ambient temperature and the minimum ambient temperature, and calculates a third difference value between the maximum ambient temperature and the minimum ambient temperature. The air conditioner can determine the target compensation value according to the preset mapping relation between the third difference value and the compensation value and the third difference value. It should be noted that the ambient temperature includes an indoor temperature or an outdoor temperature, and the target compensation value corresponding to the indoor temperature is different from the target compensation value corresponding to the outdoor temperature under the same third difference.
In the technical scheme provided by this embodiment, the air conditioner determines the ambient temperature of the air conditioner at the start-up corresponding to each of the same historical operating durations, so as to determine the target compensation value according to the difference between the maximum ambient temperature and the minimum ambient temperature, and enable the air conditioner to compensate the operating parameters according to the target compensation value, thereby ensuring the cooling effect or the heating effect of the air conditioner.
Referring to fig. 3, fig. 3 is a detailed flowchart illustrating the step 10 of fig. 2 for obtaining the target compensation value of the air conditioner, where the step S10 includes:
step S11, determining the actual operation time length of the air conditioner corresponding to the comfortable state of the last indoor environment of the air conditioner;
step S12, the actual operation duration is not matched with a preset operation duration, and a prestored compensation value is updated according to the actual operation duration and each historical operation duration to determine a target compensation value, wherein the preset operation duration is determined according to the prestored compensation value;
and step S13, matching the actual operation time length with a preset operation time length, and taking a pre-stored compensation value as a target compensation value.
In this embodiment, the compensation value is pre-stored in the air conditioner, and the current performance of the air conditioner may be different from the performance of the air conditioner when the pre-stored compensation value is determined. After the air conditioner acquires the pre-stored compensation value, the preset operation time length can be determined according to the pre-stored compensation value, namely the maximum historical operation time length corresponding to the pre-stored compensation value determined by the air conditioner is used as the preset operation time length.
The air conditioner can obtain the actual operation time corresponding to the long indoor environment reaching the comfortable state in the last operation.
The air conditioner judges whether the actual operation time length is matched with the preset operation time length, and when the difference value between the actual operation time length and the preset operation time length is large, the fact that the actual operation time length is not matched with the preset operation time length can be judged. When the actual operation duration does not match the preset operation duration, the air conditioner needs to update the pre-stored compensation value, specifically, the compensation value is re-determined for the actual operation duration and each historical operation duration to update the pre-stored compensation value, and the re-determination of the compensation value is not repeated here. And after the pre-stored compensation value is updated, the updated compensation value is saved and is used as the target compensation value.
Of course, when the actual operation duration matches the preset operation duration, the pre-stored compensation value does not need to be updated, and at this time, the pre-stored compensation value is used as the target compensation value.
Further, the air conditioner can adopt the judgment that the estimated operation time of the operation comfort function is matched with the preset operation time at the moment, and the estimated preset time can be determined according to the current indoor temperature variation of the air conditioner.
In the technical scheme provided by this embodiment, the air conditioner acquires the actual operation time length corresponding to the comfortable state of the indoor environment when the air conditioner operates last time, so as to judge whether the pre-stored compensation value needs to be updated according to the actual operation time length, thereby accurately compensating the current operation parameters of the air conditioner.
Referring to fig. 4, fig. 4 is a detailed flowchart illustrating the step S10 of fig. 2 for obtaining the target operation parameter of the air conditioner, where the step S10 includes:
step S14, determining the cold and hot feeling value of the user in the air conditioner acting space;
and step S15, acquiring target operation parameters of the air conditioner according to the cold and hot feeling values.
In this embodiment, a thermal sensation model is provided in the air conditioner, and the air conditioner determines a target operation parameter corresponding to a current thermal sensation value of a user through the thermal sensation model. The determination of the cold and hot feeling values and the target operation parameters is described above, and will not be described in detail herein.
The thermal sensation model is obtained by training when the performance of the air conditioner is normal, so that after the performance of the air conditioner is reduced, if the air conditioner still runs according to the target running parameters obtained by the thermal sensation model, the time for the indoor environment to reach a comfortable state is increased, namely after the performance of the air conditioner is reduced, the setting and determination of the parameters in the thermal sensation model do not accord with the actual performance of the air conditioner, and for this reason, the air conditioner needs to compensate the target running parameters obtained by the thermal sensation model so as to ensure the refrigerating effect or the heating effect of the air conditioner.
The invention also provides an air conditioner, which comprises a memory, a processor and a control program of the air conditioner, wherein the control program of the air conditioner is stored in the memory and can be operated on the processor, and when the control program of the air conditioner is executed by the processor, the steps of the control method of the air conditioner are realized.
