Description

Control method of air conditioner under refrigeration working condition
Technical Field
The invention belongs to the technical field of air conditioners, and particularly provides a control method of an air conditioner under a refrigeration working condition.
Background
Air conditioners have been used by more and more users as main devices for adjusting indoor temperature and humidity. In the cooling process of the air conditioner in summer, the temperature of the coil pipe is low, and the indoor temperature is reduced after indoor air passes through the coil pipe.
When the air conditioner cools, because the temperature of coil pipe is lower, also can reduce indoor humidity correspondingly because of the condensation phenomenon. In northern areas with dry summer climate, the humidity is not high enough originally, and a user does not want to dehumidify, but the indoor humidity is lower due to unreasonable temperature control of the coil pipe in the refrigeration process, so that the user cannot feel particularly comfortable. In addition, in the humid areas in the south in summer, the humidity is too high, the user wants to refrigerate and simultaneously dehumidify in a powerful mode, and due to the fact that the temperature of the coil is unreasonably controlled, when the indoor temperature reaches the habitual temperature of the user, the indoor humidity is not reduced to the habitual humidity of the user, and then the user experience is reduced.

It should be noted that the power and wind speed required for air conditioning refrigeration and dehumidification are different, and refrigeration requires high wind speed to make heat exchange more efficient and quicker, and the temperature requirement for the refrigerant is not very low.

Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. And can be adjusted as needed by those skilled in the art to suit particular applications. For example, although the description is based on the actual temperature T, the actual humidity RH and the dew point temperature TesTo determine the dew point temperature T in the roomesIt is described that this is done by looking up from a table of practical experience, but it is obvious that the invention can be used to calculate the dew point temperature TesFor example, using the Goff-Gray equation, provided that the dew point temperature T is obtainedesThat is, the methods for obtaining them are various and cannot be listed.
Example one
Referring first to fig. 1, a method for controlling an air conditioner in a cooling operation according to the present invention will be described. Fig. 1 is a flowchart illustrating a control method of an air conditioner according to the present invention under a cooling condition.
As shown in fig. 1, in order to solve the problem that the air conditioner cannot accurately control its parameters according to the actual indoor temperature and humidity conditions under the existing refrigeration condition, and further cause a large difference between the indoor humidity and the habitual humidity of the user when the indoor temperature reaches the habitual temperature of the user, the air conditioner of the present invention includes a compressor, a throttling device, an indoor fan and an indoor coil, and the control method includes:
s100, acquiring the actual temperature T and the actual humidity RH in the room.
For example, the actual temperature and humidity in the room can be detected by a detection module arranged in the air conditioner, for example, a temperature sensor and a humidity sensor are used to detect the actual temperature and humidity in the room respectively.
S200, calculating indoor dew point temperature T based on actual temperature T and actual humidity RHes。
When we obtain the actual temperature T and the actual humidity RH, the dew point temperature T in the room can be obtained through calculation or in the form of an empirical tableesFor subsequent and indoor coil temperature TpA step of comparison is prepared.

By comparing the actual temperature T with the customary temperature TsAnd actual humidity RH and customary humidity RHsThe size of (2) can determine the indoor environmental condition, judge whether indoor needs dehumidification, or need the cooling more, or both need simultaneously, both do not need to make the judgement for the numerical value of each item parameter of control air conditioner compressor, throttling arrangement and indoor fan.
S400, comparing the result and the dew point temperature TesSelectively controlling the frequency of the compressor, and/or the opening degree of the throttling device, and/or the wind speed of the indoor fan to enable the indoor coil temperature TpAnd dew point temperature TesAnd (4) adapting.
Based on the actual indoor temperature T, the actual humidity RH and the user habit temperature TsAnd the customary humidity RHsSelectively controlling the frequency of the compressor, the opening of the throttling device and the wind speed of the indoor fan to make the indoor coil pipe temperature TpAnd dew point temperature TesThe adaptation is carried out, thereby controlling the refrigeration degree and the dehumidification degree, and further leading the indoor actual temperature T to reach the habitual temperature TsAt that time, the actual humidity RH has also reached the customary humidity RHsThe standard of (2).
The control method of the air conditioner in the cooling mode according to the present invention will be described in detail with further reference to fig. 1 and 2. Wherein, fig. 2 is a logic diagram of the control method of the air conditioner under the refrigeration condition of the present invention.
As shown in FIGS. 1 and 2, in one possible embodiment, the comparison is based on the result and the dew point temperature TesThe step of selectively controlling the frequency of the compressor, and/or the opening of the throttling device, and/or the wind speed of the indoor fan "further comprises:
when T > TsAnd RH > RHsAt the same time, the frequency of the compressor is controlled to be increased, and/or the opening degree of the throttling device is controlled to be increased, so that T is enabledp≤Tes；
When T > TsAnd RH is less than or equal to RHsWhen the temperature is higher than T, the compressor is controlled to run in an up-conversion mode, and/or the throttle device is controlled to increase the opening degree, and the indoor fan is controlled to rotate in an up-conversion mode so that T is more than Tp＞Tes；
When T is less than or equal to TsAnd RH > RHsWhen the compressor is controlled to run in an up-conversion mode and/or the throttle device is controlled to increase the opening degree, and the indoor fan is controlled to reduce the rotating speed so as to enable Tp≤Tes；
When T is less than or equal to TsAnd RH is less than or equal to RHsAnd when the air conditioner is in the normal state, controlling the air conditioner to stop running.
The setting mode has the advantages that: comparing the actual temperature T with the customary temperature TsThe actual humidity RH and the customary humidity RHsThe total of four results, respectively, are:
(1)T＞Tsand RH > RHsAt this time, it is indicated that the indoor temperature is high and humid, and dehumidification and refrigeration are required at the same time, and at this time, the frequency of the compressor needs to be increased, or the opening degree of the throttling device needs to be increased, or both the two are required to be performed at the same time, so that the indoor coil temperature T is correspondingly increasedp≤TesIn this way, the humidity can be greatly reduced while the temperature is reduced.
(2)T＞TsAnd RH is less than or equal to RHsWhen the indoor temperature is high but dehumidification is not needed, the frequency-up operation of the compressor is controlled and/or the opening degree of the throttling device is controlled to be increased so as to enable Tp< T. At the same time, let Tp＞TesThe air current just can not produce a large amount of condensation when the coil pipe in the room, just also reduces relatively to humidity's influence, and at this moment, need control indoor fan rising rotational speed, just so can be under the not very low condition of coil pipe temperature, reduce indoor temperature more fast. Thus, the indoor coil temperature T is ultimately determinedpSatisfy T > Tp＞TesThe control mode is to control the compressor to run in an up-conversion mode and/or control the throttling device to increase the opening degree, and control the indoor fan to increase the rotating speed.
(3)T≤TsAnd RH > RHsWhen the indoor temperature reaches the requirement of a user and the indoor is only slightly humid, the frequency-up operation of the compressor is controlled and/or the opening degree of the throttling device is controlled to be increased correspondingly so as to enable the indoor coil temperature T to reach the requirementpDew point temperature T is less than or equal toesTherefore, the air conditioner can generate condensation to dehumidify the indoor. Meanwhile, because the indoor temperature meets the requirement, in order to ensure that the indoor temperature change is as small as possible, the indoor fan is controlled to reduce the rotating speed, so that the heat exchange between the indoor air and the coil pipe is reduced, and the air conditioner dehumidifies as much as possible under the condition of less influence on the indoor temperature. Thus, the indoor coil temperature T is ultimately determinedpSatisfy Tp≤TesThe control mode is that the compressor is controlled to run in an up-conversion mode, and/or the throttle device is controlled to increase the opening degree, and the indoor fan is controlled to reduce the rotating speed.
(4)T≤TsAnd RH is less than or equal to RHsAnd at the moment, the indoor temperature and humidity meet the requirements of users, so that the air conditioner does not need to be started, and the air conditioner is directly controlled to stop running.
Of course, when T ≦ TsAnd RH is less than or equal to RHsWhen the temperature and humidity of the room are kept, the frequency of the compressor, the opening degree of the throttling device and/or the rotating speed of the indoor fan can be controlled to maintain the frequency of the indoor temperature and humidityThe rate operation, that is to say, make the air conditioner with lower power operation, guarantee that indoor humiture can not change because of the change of external environment along with time, cause indoor humiture to be unsatisfactory. For example, the temperature may be different in the morning, the afternoon and the evening, and may still meet the user requirement at the detection time, and after five minutes, the indoor temperature may also change along with the change due to the rapid change of the external environment, and exceed the user requirement.
With continued reference to fig. 1 and 2, in one possible embodiment, the step S200 is preferably based on the actual temperature T, the actual humidity RH and the dew point temperature TesCorresponding relation, determining indoor dew point temperature Tes. That is, the dew point temperature T is directly inquired based on the actual temperature T and the actual humidity RH through an empirical data tablees。
In a possible implementation, after step S200, the method may further include: every t1Time, based on the actual temperature T and the actual humidity RH, the dew point temperature T in the room is updatedes。
In one possible implementation, similarly, the habit information of the user in step S300 may be also be set at intervals of t2The time is updated once.
The setting mode has the advantages that: the corresponding dew point temperature T is directly inquired through the actual temperature T and the actual humidity RHesAnd is convenient and quick. Normally, during the adjustment of the room temperature, the actual temperature T and the actual humidity RH in the room are also changing, and the dew point temperature T is thenesAlso varying, in order to obtain a real-time dew point temperature TesMore precisely, a step of updating the dew point temperature is added. Similarly, the habitual temperature and the habitual humidity of the user are different in four seasons, for example, the habitual temperature of the indoor user is about 25 ℃ in summer and about 21 ℃ in winter, and the habitual temperature and the habitual humidity of the user may also be changed according to different time, and t2The time is updated once, so that the use habit of the user can be better fitted.
In summary, the control method of the invention can control the refrigeration degree and dehumidificationTo such an extent that the actual indoor temperature T reaches the customary temperature TsAt that time, the actual humidity RH has also reached the customary humidity RHsThe standard of (2). Updating the actual temperature T and the actual humidity RH to obtain the dew point temperature TesAnd is more accurate. By updating the habit information of the user, the use habit of the user can be better fitted.
It should be noted that the above-mentioned embodiments are only used for illustrating the principle of the present invention, and are not intended to limit the protection scope of the present invention, and those skilled in the art can modify the above-mentioned structure so that the present invention can be applied to more specific application scenarios without departing from the principle of the present invention.
For example, in an alternative embodiment, the dew point temperature T is derivedesCan obviously also be obtained by calculation, for example by using the goff-gray formula, provided that the dew point temperature T is obtainedesThat is, these do not depart from the principle of the present invention and thus fall within the scope of the present invention.
Although the above embodiments describe the steps in the above sequential order, it can be understood by those skilled in the art that, in order to achieve the effect of the present embodiment, the steps are not necessarily performed in the order, and may be performed simultaneously (in parallel) or in the reverse order, for example, "calculating the dew point temperature T in the roomes"AND" compares the actual temperature T with the customary temperature TsThe actual humidity RH and the customary humidity RHsThe two steps do not have a sequential order, although the invention contemplates the calculated dew point temperature TesThe actual temperature and humidity are compared with the conventional temperature and humidity, but obviously, the steps of the actual temperature and humidity and the conventional temperature and humidity can be reversed or paralleled, and the simple changes are all within the protection scope of the invention.
In the first embodiment, how to control the air conditioner is mainly described, so that a user can keep a relatively comfortable and balanced temperature and humidity in a room after going home from work. However, the air conditioning system is not suitable for being always turned on, the indoor temperature and humidity can be adjusted all the time, the electric energy can be more efficiently utilized only when the air conditioning system is turned on for a period of time before a user is about to arrive at home, the energy waste is prevented, and particularly, the temperature needs to be accurately controlled due to high power consumption.
In the prior art, a user usually sets a preset starting time, such as 6:00 pm, and an air conditioner sets a fixed air conditioning time, such as 30min, of indoor temperature and humidity, so as to determine an advanced starting time, and if the preset starting time is 6:00 pm and the fixed air conditioning time is 30min, the advanced starting time is 5:30 pm.
However, the preset starting time of the user is not 6:00 every time, that is, the user is not 6:00 home every time, so that the situation that the user is started in advance, energy is wasted, the user is started after the user is delayed, and the user experience is poor may be caused. In addition, within a fixed air conditioning time of 30min, if the external environment is not referred to, the adjustment cannot be completed at every time, and further misjudgment is made on the early opening time, which may also cause energy waste or poor user experience.
How to accurately determine the preset starting time and how to ensure the fixed air conditioning time, and how to ensure the accuracy of the early starting time through the preset starting time and the fixed air conditioning time are emphasized in the second embodiment to the fourth embodiment.
Example two
In order to solve the problem that the preset startup time and the air conditioning time are not accurate enough in the prior art, the compensation for the preset startup time and the air conditioning time is added before the step S100 in the first embodiment of the present invention.
Referring to fig. 3, in which fig. 3 is a flowchart illustrating a control method of an air conditioner under a cooling condition according to a second embodiment of the present invention.
As shown in fig. 3, in a preferred embodiment, the method for controlling an air conditioner further includes:
s110, acquiring the preset starting time and the outdoor environment temperature of the air conditioner.
The preset starting time in this embodiment may be a starting time actively set by a user, or a starting time statistically obtained based on a historical starting time of the air conditioner. For example, the preset starting time may be a starting time set by a user through a remote controller, a mobile phone APP, or a starting time obtained by a controller of the air conditioner or a cloud server through statistics according to a historical actual starting time of the air conditioner, for example, an average value of historical actual starting times obtained through statistical calculation of the historical actual starting time of the air conditioner by using statistical methods, probability theory calculation, and other methods is used as the preset starting time of the air conditioner. The following explains the control method by taking the cloud server as an example to perform statistical calculation.
And S111, correcting the preset starting-up time based on the time correction parameter.
The time correction parameter is used to represent a corresponding relationship between the preset startup time and the actual startup time, that is, a deviation between the preset startup time and the actual startup time, which is set or calculated by a user. After the preset starting time is set by a user or calculated by the air conditioner, the starting time is corrected based on the time correction parameter, and if the preset starting time is corrected by increasing or decreasing a time period on the basis of the determined preset starting time, the corrected preset starting time can be closer to the real starting time of the user. For example, if the preset power-on time is 18:00 and the time correction parameter is +10min, the corrected preset power-on time is 18:00+10min, which is 18: 10.
In a preferred embodiment, the time correction parameter is determined during the last operation of the air conditioner. Specifically, when the air conditioner receives a start-up instruction for the last time, if the air conditioner receives the start-up instruction in the same time period of the previous day or the same time period of the previous days, the current actual start-up time is recorded first, then the historical preset start-up time and the historical actual start-up time in the set days before (including this time) this time are counted, and the average value of the historical preset start-up time and the average value of the historical actual start-up time in the set days are calculated respectively. And then calculating a first difference value between the average value of the historical actual starting-up time and the average value of the historical preset starting-up time, and storing the first difference value as a time correction parameter for the next correction of the preset starting-up time.
For example, the cloud server counts historical preset starting-up time and historical actual starting-up time of the air conditioner in the same period (e.g., 18:00-19:00) of the past 7 days including this time, and calculates a mean value of all historical preset starting-up time and a mean value of all historical actual starting-up time, if the mean value of the historical preset starting-up time is calculated to be 18:30 and the mean value of the historical actual starting-up time is calculated to be 18:40, then the first difference is equal to 18:40-18: 30-10 min, that is, the time correction parameter is 10min, that is, in the past 7 days, the actual starting-up time of the user is 10min later than the preset starting-up time on average. Therefore, when the preset starting-up time is estimated next time, the sum of the estimated preset starting-up time and the time correction parameter is calculated to serve as the corrected preset starting-up time, and therefore the estimation accuracy of the preset starting-up time is improved, energy waste is reduced, and user experience is improved. Of course, the time correction parameter in the above example is described as a positive number, and the same holds true for the present control method if the time correction parameter obtained is a negative number. If the time correction parameter is-10 min, the actual starting time of the user in the past 7 days is 10min earlier than the preset starting time on average, and therefore when the preset starting time is estimated next time, the estimation accuracy of the preset starting time can be improved by calculating the sum of the preset starting time and the time correction parameter, namely subtracting 10min from the preset starting time to serve as the corrected preset starting time.
And S112, determining air conditioning time based on the outdoor environment temperature.
Acquiring the outdoor environment temperature of the position of the air conditioner at the same time, before or after the preset starting time of the air conditioner is acquired, for example, acquiring the outdoor environment temperature through a temperature sensor and the like arranged on an outdoor unit; then, based on the outdoor ambient temperature, the air conditioning time is determined, for example, after the outdoor ambient temperature is determined, the cloud server calculates the air conditioning time matched with the outdoor ambient temperature based on the outdoor ambient temperature.
Preferably, the air-conditioning time may be calculated based on a fitting formula between the outdoor ambient temperature and the air-conditioning time. For example, the air conditioning time is calculated using the following formula (1):
t＝k×Tao+b (1)
in equation (1), t represents the air conditioning time, Tao is the outdoor ambient temperature, and k and b are constants that can be fit based on experimental data. For example, a plurality of control experiments are performed for different outdoor ambient temperatures and air conditioning times, thereby establishing a linear relationship of the air conditioning time and the outdoor ambient temperature.
Of course, the determination of the air-conditioning time may also be performed based on other relationships between the outdoor ambient temperature and the air-conditioning time, such as the determination based on the fixed corresponding relationship between the outdoor ambient temperature and the air-conditioning time. If a comparison table of the outdoor environment temperature and the air conditioning time is determined based on an air conditioning test, the air conditioning time determined by the outdoor environment temperature is determined by using the comparison table.
The setting mode has the advantages that: since different outdoor ambient temperatures have a great influence on the air conditioning capacity of the air conditioner, the accuracy of the air conditioning time can be ensured and the energy is prevented from being excessively wasted by determining the air conditioning time by using a fitting formula or a corresponding relationship between the outdoor ambient temperature and the air conditioning time.
S113, determining an advanced starting time based on the air conditioning time and the corrected preset starting time;
calculating the early starting time of the air conditioner based on the corrected preset starting time and the air conditioning time compensated by the outdoor environment temperature; after the preset power-on time is corrected, the turning-on timing of the air conditioning mode can be determined based on the air conditioning time. For example, if the air conditioning time of the air conditioner is 5min, the advanced start-up time is 18:05 when the corrected preset start-up time is 18: 10.
And S114, when the early opening time is reached, opening the step S100.
And when the time reaches the opening-in-advance time, controlling the air conditioner to regulate the indoor temperature and humidity.
According to the control method of the air conditioner, the preset starting time can be corrected based on the time correction parameter, and the accuracy of time estimation is improved. Specifically, the preset starting-up time is corrected based on the time correction parameter, and the control method can correct the preset starting-up time based on the starting-up habit of the user, so that the corrected preset starting-up time is closer to the real starting-up time of the user, the accurate and personalized treatment for a single user is realized, and the user experience is improved. In addition, the air conditioning time is determined based on the outdoor environment temperature, and because different outdoor environment temperatures have great influence on the air conditioning capacity of the air conditioner, the air conditioning time is determined by utilizing a fitting formula or a corresponding relation between the outdoor environment temperature and the air conditioning time, so that the accuracy of the air conditioning time is further ensured, and the energy is prevented from being excessively wasted.
EXAMPLE III
Embodiment three of the present invention is based on embodiment two, and the step of determining the air-conditioning time based on the outdoor ambient temperature is removed, and a fixed air-conditioning time is directly specified. Because, as long as properly adjusting the parameters of the air conditioner such as the frequency of the compressor, the rotating speed of the blower and the like, the adjustment can be ensured to be completed within fixed air conditioning time each time. However, the air conditioning time of the second embodiment has a certain error, and therefore the finally determined advanced opening timing has a certain error, but the error is within an acceptable range.
Specific embodiments refer to fig. 4, where fig. 4 is a flowchart of a control method of an air conditioner under a cooling condition according to a third embodiment of the present invention.
As shown in fig. 4, in one possible embodiment, the method for controlling an air conditioner further includes:
s120, acquiring a preset starting time of the air conditioner;
s121, correcting the preset starting-up time based on the time correction parameter;
s122, determining an advanced starting time based on the preset air conditioning time and the corrected preset starting time;
and S123, when the early opening time is reached, opening the step S100.
Example four
In the fourth embodiment of the invention, on the basis of the second embodiment, the step of correcting the preset starting-up time based on the time correction parameter is eliminated. Correspondingly, however, since the fourth embodiment lacks a step of correcting the preset boot-up time, there is a certain error with respect to the second embodiment, but the error is within an acceptable range.
Referring to fig. 5, in a specific embodiment, fig. 5 is a flowchart of a control method of an air conditioner under a cooling condition according to a fourth embodiment of the present invention.
As shown in fig. 5, in one possible embodiment, the control method of an air conditioner further includes:
s130, acquiring a preset starting time and an outdoor environment temperature of the air conditioner;
s131, determining air conditioning time based on the outdoor environment temperature;
s132, determining an early starting time based on the air conditioning time and the preset starting time;
and S133, starting the step S100 when the early starting time is reached.
In the second to fourth embodiments, we all start the air conditioner in advance, and then optimize the time of the start in advance in various ways, but if the user has irregular life in a period of time, for example, the user frequently goes on a business trip, or if the time of returning home is unstable due to frequent overtime, it needs to be determined whether to start the step S100 to regulate the indoor air. In view of the above problem, a fifth embodiment of the present invention provides a determination method to determine whether to start the step S100.
EXAMPLE five
In order to solve the problem that the air conditioner cannot autonomously judge whether to adjust the indoor air when the life of a user is irregular, the step of predicting whether to start the air conditioner is added before the step of S100.
Fig. 6 and 7 show specific embodiments, where fig. 6 is a flowchart illustrating a control method of an air conditioner under a cooling condition according to a fifth embodiment of the present invention, and fig. 7 is a schematic diagram illustrating a scoring system according to the fifth embodiment of the present invention.
As shown in fig. 6, in a preferred embodiment, the control method of the air conditioner further includes:
and S141, when the predicted time point is reached, calculating the probability score of the air conditioner starting at the current early starting time based on a pre-established scoring system.
The scoring system is used for representing the corresponding relation between historical operation information and historical prediction information of the air conditioner and the probability score of the air conditioner for starting the air conditioner at the next early starting moment. The advanced opening time is the same as in the above-described embodiments two to four, the predicted time point is a certain time point before the advanced opening time, the advanced opening time is 19:00, and the predicted time point may be 1 hour before 19:00, that is, 18: 00.
The cloud server calls a pre-established scoring system to calculate the probability score of the air conditioner being started in advance at 19:00, namely the probability of the air conditioner being started in advance at 19: 00. The scoring system is used for representing the corresponding relation between historical operation information and historical prediction information of the air conditioner and the probability score of the air conditioner for starting the air conditioner at the next early starting moment, namely after 19:00 is input into the scoring system, the scoring system can calculate the probability of starting the air conditioner in advance at the time point based on the historical operation information and the historical prediction information of the air conditioner.
In a preferred embodiment, step S141 may further include: inputting the next early opening time into a pre-trained air conditioner opening probability model to obtain the historical opening probability of the air conditioner opening at the next early opening time; obtaining the recent starting probability based on the number of days for starting the air conditioner at the next advanced starting time within the set number of days; obtaining historical prediction accuracy of the next early opening moment based on historical prediction information; calculating the probability score of the air conditioner for starting the air conditioner at the next early starting moment based on the historical starting probability, the recent starting probability and the historical prediction accuracy; the air conditioner starting probability model is used for representing the corresponding relation between the historical operation information and the historical starting probability. Specifically, as shown in fig. 7, in the present embodiment, after the early turn-on time is input into the scoring system, the score calculated by the scoring system is derived from three parts, the first part is the historical turn-on frequency calculated based on the trained air conditioner turn-on probability model; the second part is a recent opening probability obtained based on the number of times of opening within a set number of days at the early opening time; the third part is history prediction accuracy of the early opening time obtained based on history prediction information; the probability score can be weighted values of historical opening probability, recent opening probability and historical prediction accuracy, and the weights of the three parts in the scoring system can be 70 points, 15 points and 15 points respectively.
In the first part, the process of establishing the air conditioner starting probability model may specifically be: and establishing a model by taking the historical time of opening the air conditioner in advance, the starting times corresponding to the time of opening the air conditioner and the total running days of the air conditioner as characteristic data to obtain the corresponding relation between the historical time of opening the air conditioner in advance and the historical opening probability, and inputting the early opening time into the model so as to output the historical opening probability corresponding to the early opening time. In the second part, the set number of days may be the last 7 days, the recent opening probability of the last 7 days with the number of opening days increased by 1 day is increased by 20%, and when the number of opening days is more than 5 days, the recent opening probability is 100%. In the third part, the historical prediction information may be a ratio of a predicted correct number to a predicted total number in the historical prediction of the early opening time.
For example, after the next early starting time is 19:00 and is input into the scoring system, the historical starting probability of the starting air conditioner at the starting time is calculated by the probability model of starting the air conditioner to be 80 percent; if the number of opening days in nearly 7 days is 4 days, the recent opening probability is 80 percent; the correct number of predictions at the early opening time of 19:00 is 7 times, the total number is 10 times, namely the prediction accuracy is 70%; from this, the three probabilities are multiplied by their weights, respectively, and summed to obtain a probability score P of 80% × 70+ 80% × 15+ 70% × 15 of 78.5.
And S142, when the probability score is larger than the set threshold and the early opening time is reached, the step S100 is carried out.
For example, on the premise of a full score of 100, the scoring system calculates the probability score of turning on the air conditioner in advance at 19:00 to be 80 minutes at 18:00 (namely, the probability of turning on the air conditioner in advance is 80%), which proves that a user is very likely to use the air conditioner after 19:00, and at the moment, when the moment of turning on in advance is reached, the cloud server issues an instruction of turning on the step S100, so that the air conditioner is turned on at 19:00 and starts to adjust the indoor temperature and humidity. For another example, the scoring system calculates that the probability score of turning on the air conditioner in advance is 50 points at 19:00, which proves that the user is most likely not to use the air conditioner after 19:00, and the cloud server controls the air conditioner not to turn on the step S100.
Further, in a preferred embodiment, the predicted time point may be determined based on the following method:
the predicted time point is selectively determined based on historical operation information of the air conditioner. Specifically, based on historical operation information of the air conditioner, judging the activity of the air conditioner; when the activity of the air conditioner is high, counting the operation times of the air conditioner in a plurality of operation time periods within set days; selecting a plurality of operation time periods with operation times larger than the set times from a plurality of operation time periods; respectively calculating the average value of the starting time when all the air conditioners are started in advance in each selected operation time period as the advanced starting time of the operation time period; and calculating the difference value of each advanced opening time and a preset time period as a predicted time point of the advanced opening time. For example, the activity of the air conditioner may be defined as whether there is a startup behavior in the past few days (e.g., the past 3 days), when there is a startup record in the past few days, the activity of the air conditioner is high, otherwise, the activity is low. When the activity degree is low, the user is proved to have less times of using the air conditioner, the probability of opening the air conditioner is lower, and whether the air conditioner is opened or not is not predicted at the moment. When the activity of the air conditioner is high, the fact that a user uses the air conditioner frequently is proved, habits and rules of using the air conditioner are easier to analyze, the operation times of the air conditioner in a plurality of operation periods within set days (such as within the last 7 days) are counted, for example, the operation times of the air conditioner in a plurality of operation periods are counted by 1 hour in an aggregation mode, then a plurality of periods with the operation times being more than 4 times within 7 days are selected from the plurality of operation periods, then the average value of all the startup moments within each period is respectively calculated to serve as the early startup moment of the operation period, and finally the time point obtained by subtracting 1 hour from each early startup moment is used as the predicted time point, if a certain early startup moment is 19:00, then 18:00 is the predicted time point of the early startup moment.
Through the control mode, the control method can improve the intelligent degree and the user experience of the air conditioner. Specifically, when the predicted time point is reached, the probability score of the air conditioner for starting the air conditioner at the next early starting time is calculated based on the scoring system, the control method can reasonably predict the probability of the air conditioner for starting the air conditioner at the next early starting time based on the historical information of the air conditioner used by a user, and therefore when the probability of starting the air conditioner is high, the air conditioner is started after the early starting time comes, the step S100 is controlled to be started, and indoor temperature and humidity are controlled to be balanced at the same time. In addition, the prediction process is completely and automatically completed, so that the control method can improve the intelligent degree of the air conditioner and improve the user experience.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
