Exemplarily, the execution subject of the embodiment of the present application is an electronic device, and the electronic device is a water heater or a server, or the electronic device may also be a terminal, such as a central control device in a smart home environment.

FIG. 2 is a schematic flowchart of a water heater control method according to an embodiment of the present application. As shown in Figure 2, the method includes:

S201. Determine the ambient temperature range to which the ambient temperature belongs.

In this embodiment, the ambient temperature can be obtained through a temperature sensor set in the outdoor environment or the indoor environment of the area where the water heater is located; or, the ambient temperature in the area where the water heater is located can be obtained by querying the network, for example, sending the environment to the server or terminal The temperature query request receives the ambient temperature returned by the server or terminal. After the ambient temperature is obtained, the ambient temperature interval to which the ambient temperature belongs is determined among the plurality of pre-divided ambient temperature intervals. For example, the plurality of pre-divided ambient temperature intervals include Te ≤ 0°C, 0°C<T _e ≤ 10°C, 10°C<T _e ≤ 20° _C , and _Te >20°C. Wherein, T _e represents the ambient temperature, and °C represents the degree Celsius. If the currently obtained ambient temperature is -2°C, it is determined that the ambient temperature range to which the ambient temperature belongs is T _e ≤ 0°C.

S202. Determine the target setting temperature according to the ambient temperature range.

The somatosensory sensation of the user is different in different ambient temperature ranges. For example, when the ambient temperature is in the ambient temperature range of T _e ≤ 0°C, the user feels the highest degree of coldness, and when the ambient temperature is in the ambient temperature range of 0°C <T _e ≤ 10°C, the user feels the coldness degree is obvious When the ambient temperature is in the ambient temperature range of 10°C <T _e ≤ 20°C, the user feels the coldness is significantly reduced again. When the ambient temperature is in the ambient temperature range of T _e > 20°C, the user may already feel the surrounding The environment is a bit hot.

Therefore, after determining the ambient temperature interval to which the current ambient temperature belongs, a target setting temperature suitable for the ambient temperature interval can be determined, so as to control the outlet water temperature of the water heater based on the target setting temperature and improve the user's water experience.

In an example, the correspondence between multiple ambient temperature intervals and multiple setting temperatures may be preset. In this correspondence, one ambient temperature interval may correspond to one setting temperature, and different temperature intervals correspond to different setting temperatures. Based on this, It can be determined that the target setting temperature is the setting temperature corresponding to the ambient temperature interval to which the current ambient temperature belongs. The correspondence between the multiple ambient temperature ranges and the multiple set temperatures can be obtained by collecting the user's water usage habits in different ambient temperature ranges, or set by the R&D personnel based on implementation and experience.

S203. Determine the target working mode according to the ambient temperature range.

Among them, the water heater has different working modes, and the power consumption and heating efficiency of the water heater are different in different working modes. In different ambient temperature ranges, users have different physical sensations, and users have different preferences for the working mode of the water heater. For example, when the ambient temperature is in the ambient temperature range of T _e ≤ 0°C, the user prefers the water heater to heat the water temperature with faster efficiency, and when the ambient temperature is in the ambient temperature range of T _e > 20°C, the user prefers the water heater to save energy. way to heat the water temperature.

Therefore, after determining the ambient temperature interval to which the current ambient temperature belongs, a target working mode suitable for the ambient temperature interval can be determined, and a suitable water heater working mode can be provided for the user.

In an example, the correspondence between multiple ambient temperature intervals and multiple operating modes may be preset. In this correspondence, one ambient temperature interval corresponds to one working mode, and different ambient temperature intervals may correspond to the same or different working modes. Based on this, it can be determined that the target working mode is the working mode corresponding to the ambient temperature interval to which the current ambient temperature belongs. The correspondence between the multiple ambient temperature ranges and the multiple working modes may be obtained by collecting the user's working mode setting habits in different ambient temperature ranges, or may be set by the R&D personnel based on implementation and experience.

Optionally, the working modes of the water heater include a quick heating mode and an energy saving mode, and the energy saving mode may be a heat pump mode. In the heat pump mode, the water heater uses a heat pump to heat water temperature to achieve an energy saving effect. At this time, a possible implementation manner of S203 includes: according to the ambient temperature interval, determining the target working mode in the fast heating mode and the energy saving mode. Therefore, based on the ambient temperature, the working mode of the water heater can be flexibly adjusted between the quick heating mode and the energy saving mode.

For example, the working modes corresponding to the ambient temperature ranges of T _e ≤ 0°C, 0° C <T _e ≤ 10° C, and 10° C <T _e ≤ 20° C are all rapid heating modes, and the ambient temperature range of _Te > 20° C. The corresponding working mode is the heat pump mode. If the ambient temperature range to which the current ambient temperature belongs is T _e ≤ 0°C, 0° C <T _e ≤ 10° C, and 10° C <T _e ≤ 20° C, the target working mode is determined to be the fast heating mode; if The ambient temperature range to which the current ambient temperature belongs is _Te >20°C, and the target working mode is determined to be the energy-saving mode.

S204, control the heating of the water heater according to the target setting temperature and the target working mode.

In this embodiment, if the current device is a server or a terminal, an instruction will be sent to the water heater, instructing the water heater to perform heating according to the target set temperature and target working mode. If the current device is a water heater, the processor adjusts its own set temperature to the target set temperature, switches its own working mode to the target working mode, and then conducts heating according to the target set temperature and the target working mode.

The water heater control method provided by the embodiment of the present application determines an appropriate target setting temperature and target working mode for the water heater based on the ambient temperature range to which the ambient temperature belongs, and controls the heating of the water heater according to the target setting temperature and target working mode. On the one hand, the automatic setting and adjustment of the set temperature and working mode of the water heater is realized, which improves the convenience and intelligence of the water heater control; on the other hand, the accuracy and rationality of the set temperature and working mode setting of the water heater are improved. .

In some embodiments, the target setting temperature may be determined in combination with the ambient temperature and historical water consumption data in the ambient temperature interval, so as to improve the accuracy of the target setting temperature by utilizing the historical water consumption data reflecting the user's water consumption habits in the ambient temperature interval. Based on this, FIG. 3 is a schematic flowchart of a water heater control method provided by another embodiment of the present application. As shown in Figure 3, the method includes:

S301. Determine the ambient temperature range to which the ambient temperature belongs.

Wherein, the implementation principle and technical effect of S301 may refer to the foregoing embodiments, which will not be repeated.

S302. Determine the target setting temperature according to the setting times of the multiple historical setting temperatures and the multiple historical setting temperatures and the ambient temperature in the ambient temperature interval.

Among them, when the current device is a server or terminal that manages multiple water heaters, it can pre-collect the historically set temperatures of multiple water heaters and the number of historically set temperature settings in multiple ambient temperature ranges; when the current device is a water heater, the water heater can collect multiple The historical setting temperature and the setting times of the historical setting temperature in the ambient temperature range. In this way, multiple historical setting temperatures and the setting times of multiple historical setting temperatures under multiple ambient temperature intervals are obtained, and stored in the database.

In this embodiment, a plurality of historical setting temperatures and a plurality of historical setting temperatures in the ambient temperature interval to which the current ambient temperature belongs can be obtained from a database that stores the historical setting temperatures and the setting times of the historical setting temperatures in multiple ambient temperature intervals Set the number of times to set the temperature. For example, the ambient temperature range to which the current ambient temperature belongs is T _e ≤ 0°C, and the historically set temperatures in this ambient temperature range obtained from the database include 60°C, 65°C, ... etc., and the historical set temperature of 60°C The number of settings is 200, and the number of settings for the historical setting temperature of 65°C is 100.

In some embodiments, a possible implementation of S302 includes: determining the target setting temperature as the historical setting temperature with the largest number of settings among multiple historical setting temperatures; or, determining the target setting temperature as the average value of the multiple historical setting temperatures.

In some embodiments, another possible implementation manner of S302 includes: determining the average value of the multiple historical setting temperatures according to the multiple historical setting temperatures and the setting times of the multiple historical setting temperatures; determining the target according to the average value and the ambient temperature Set the temperature to improve the accuracy of the target set temperature.

Specifically, in the temperature prediction model, for each historical setting temperature, the historical setting temperature is multiplied by the setting times of the historical setting temperature to obtain the product, and after adding the products of each historical setting temperature, it is divided by a plurality of historical setting temperatures The sum of the setting times of , obtains the average value of multiple historical setting temperatures. Considering that the average value of multiple historical setting temperatures is obtained based on the ambient temperature range, if the current ambient temperature is low, the average value of multiple historical setting temperatures may still be low under the current ambient temperature. If the temperature is high, the average value of multiple historical setting temperatures may be a high temperature under the current ambient temperature. Therefore, after obtaining the average value of multiple historical setting temperatures, the average value can be corrected based on the ambient temperature to obtain the target setting temperature.

In the process of revising the mean value based on the ambient temperature, that is, in the process of determining the target setting temperature according to the mean value and the ambient temperature, a possible implementation method includes: according to the weight corresponding to the ambient temperature and the mean value of multiple historical setting temperatures The corresponding weights are weighted summation of the ambient temperature and the average of multiple historical setting temperatures to obtain the target setting temperature. Therefore, the correction of the mean value based on the ambient temperature is implemented by means of weighted summation, in which the influence of the ambient temperature on the target setting temperature can be adjusted by setting a corresponding weight for the ambient temperature. Among them, a smaller weight can be set for the ambient temperature, and a larger weight can be set for the average value of multiple historical setting temperatures. While determining the target setting temperature mainly based on the historical water usage habits, the current ambient temperature is also taken into account.

Optionally, the weight corresponding to the ambient temperature and the weight corresponding to the average value of multiple historically set temperatures are preset. For example, the weight corresponding to the ambient temperature is preset as 0.2, and the weight corresponding to the average value of multiple historically set temperatures is preset as 0.8.

Optionally, the weight corresponding to the ambient temperature is determined according to the magnitude relationship between the ambient temperature and the first threshold. If the ambient temperature is greater than the first threshold, the weight corresponding to the ambient temperature is determined to be the preset first value; if the ambient temperature is equal to the first threshold, the weight corresponding to the ambient temperature is determined to be the preset second value; if the ambient temperature is less than If the first threshold is used, the weight corresponding to the ambient temperature is determined to be a preset third value. Wherein, the first value is smaller than the second value, and the second value is smaller than the third value. In this way, on the one hand, the flexible adjustment of the weight corresponding to the ambient temperature is realized. Correct the mean to improve the accuracy of the target set temperature.

For example, the value range of the weight corresponding to the ambient temperature is [-0.2, 0.2]. If the ambient temperature is less than 0 (in this case, 0 is the first threshold), the weight corresponding to the ambient temperature is 0.2 (ie, the third value is 0.2). If the ambient temperature is equal to 0, the weight corresponding to the ambient temperature is 0.1 (ie, the second value is 0.1). If the ambient temperature is greater than 0, the weight corresponding to the ambient temperature is -. 02 (ie the first value is -0.1). Therefore, when the ambient temperature is low, the average value of multiple historical setting temperatures is compensated by the method of weighting the ambient temperature, which plays the role of increasing the target setting temperature. The weighting method reduces the average value of multiple historical setting temperatures, which plays the role of reducing the target setting temperature.

Further, the calculation formula of the target setting temperature can be expressed as:

Among them, T _t represents the target setting temperature, L represents the weight corresponding to the ambient temperature, T _e represents the ambient temperature, _0.8 is the average value of multiple historical setting temperatures, T _h1 , T _h2 ,  … The _1st , _2nd , _... , the _{xth historical} setting temperature in the _ambient temperature range of frequency.

In some embodiments, the historical setting temperature and the setting times of the historical setting temperature in multiple ambient temperature intervals may be stored on the server and obtained from the server, and the setting temperature on the water heater under multiple ambient temperature intervals may also be collected in real time, Set the temperature setting times to update the historical setting temperature and the historical setting temperature setting times in multiple ambient temperature ranges stored on the server in time, so as to improve the reliability and accuracy of these historical data stored on the server, thereby improving the reliability and accuracy of the historical data stored on the server. This historical data determines the accuracy of the target set temperature.

S303. Determine the target working mode according to the ambient temperature range.

The implementation principle and technical effect of S303 may refer to the foregoing embodiments, and details are not repeated here.

In some embodiments, the total time interval is divided into multiple time intervals, where the total time interval may be one day or one week. In different time intervals within the total time interval, the water heater working mode preferred by the user may be different. For example, 6 am to 9 am and 6 pm to 10 pm are the washing time of users in the home. In these two time intervals, users expect the water heater to heat more efficiently, so users prefer quick heating. mode, the user's water demand decreases during other time periods, and the user prefers the energy-saving mode. For another example, during a week's working day, the user is short on time and prefers the fast heating mode, and on a week's rest day, the user has ample time and prefers the energy-saving mode. Therefore, after the unit time is divided into multiple time intervals, the cumulative setting times of multiple working modes under different ambient temperature intervals and different time intervals can be collected and recorded. For example, the cumulative set times of a plurality of operation modes in each time interval under the ambient temperature interval of 0°C to 10°C. Based on this, a possible implementation manner of S303 includes: determining the time interval in which the current time is located; determining the target working mode according to the ambient temperature interval and the working mode historical setting data under the time interval, wherein the working mode historical setting data includes multiple The cumulative setting times of each working mode. Therefore, combined with the ambient temperature range where the ambient temperature is located, and the cumulative setting times of multiple working modes in the time range where the current time is located, the target working mode is determined, and the influence of environmental factors and time factors on the working mode setting is comprehensively considered, which effectively improves the target. The accuracy and rationality of the working mode.

Optionally, when dividing the time interval, take 24 hours as the total time interval and 8 hours as the unit time interval, divide the 24 hours into multiple 8-hour time intervals, and collect data from multiple ambient temperature intervals. The cumulative setting times of multiple working modes in every 8 hours.

Optionally, when dividing the ambient temperature interval, the division is performed every 5 degrees. For example, the divided ambient temperature ranges include -20°C～-15°C, -15°C～-10°C, -10°C～-5°C, -5°C～0°C, 0°C～5°C, 5°C ~10°C, 10°C to 15°C, . . . and so on.

Optionally, in the process of determining the target working mode according to the working mode historical setting data in the ambient temperature interval and the time interval, the target working mode is determined as the working mode with the largest cumulative number of settings in the working mode historical setting data. Among them, the working mode with the largest cumulative number of settings in the ambient temperature interval and the time interval is reflected to a certain extent as the user's most preferred working mode.

Optionally, in the case of multiple working modes including quick heating mode and energy saving mode, if the ambient temperature range to which the ambient temperature belongs and the working mode historical setting data in the time range where the current time is located, the cumulative setting times of the quick heating mode is If it is greater than the cumulative setting times of the energy-saving mode, the target working mode is determined to be the fast heating mode, otherwise, the target working mode is determined to be the energy-saving mode. Thus, flexible and reasonable settings of the energy-saving mode and the quick-heating mode of the water heater are realized.

S304 , control the heating of the water heater according to the target setting temperature and the target working mode.

Wherein, the implementation principle and technical effect of S304 may refer to the foregoing embodiments, which will not be repeated.

In some embodiments, considering that the target setting temperature determined through the above process may occasionally deviate once or twice, after the target setting temperature is determined, the target setting temperature may be corrected, and then the corrected target setting temperature and The target operating mode controls the heating of the water heater. Based on this, a possible implementation manner of S304 includes: if the target setting temperature is less than the second threshold corresponding to the ambient temperature interval to which the ambient temperature belongs, updating the target setting temperature to be the second threshold. Among them, different ambient temperature intervals correspond to different second thresholds, and the second threshold can be understood as the lowest setting temperature required by the ambient temperature interval. If the target setting temperature is lower than the setting temperature, the outlet water temperature will be too low, causing The user is uncomfortable, so the set temperature can be used as the target set temperature.

Optionally, if the target setting temperature is greater than or equal to the second threshold corresponding to the ambient temperature interval to which the ambient temperature belongs, the target setting temperature is kept unchanged.

For example, the multiple ambient temperature ranges include T _e ≤ 0°C, 0°C<T _e ≤ 10°C, 10°C<T _e 20°C, where _{Te ≤ 0°C, 0°C<T e ≤} 10°C, 10°C The second threshold values corresponding to <T _e ≤ 20°C are 60°C, 55°C, and 50°C, respectively. When the ambient temperature range to which the ambient temperature belongs is _Te ≤ 0°C, it is determined whether the target setting temperature is less than 60°C, and if so, the target setting temperature is determined to be 60°C. When the ambient temperature range to which the ambient temperature belongs is 0°C<T _e≤10 °C, determine whether the target setting temperature is less than 55°C, and if so, determine the target setting temperature is 55°C. When the ambient temperature range to which the ambient temperature belongs is 10°C<T _e ≤ 20°C, determine whether the target setting temperature is less than 50°C, and if so, determine the target setting temperature is 50°C.

In some embodiments, the historical setting data of the working mode under multiple ambient temperature intervals and multiple time intervals may be stored on the server and obtained from the server, and the data of the water heater in multiple ambient temperature intervals and multiple time intervals may be collected in real time. Working mode, count the setting times of working mode, and update the historical setting data of multiple ambient temperature intervals and multiple time intervals stored on the server in time to improve the reliability and accuracy of the historical setting data of working mode stored on the server. This improves the accuracy of determining the target work mode based on the work mode historical setting data.

In the water heater control method provided by the embodiment of the present application, after determining the ambient temperature interval to which the ambient temperature belongs, the historical data in the ambient temperature interval, for example, the historical setting temperature, the setting times of the historical setting temperature, and the historical setting data of the working mode are used to determine Determine the target set temperature and target work mode, improve the accuracy and rationality of the target set temperature and target work mode, thereby improve the accuracy and rationality of water heater control, and improve the intelligence of the water heater.

In some embodiments, if the ambient temperature interval to which the ambient temperature belongs is the ambient temperature interval with the largest temperature value among the plurality of ambient temperature intervals, the target set temperature is determined to be the preset temperature. Therefore, when the ambient temperature is in an ambient temperature range with a larger temperature value, it can be determined that the user's water demand can be met by using the preset temperature, and the above-mentioned calculation process of the target setting temperature is not required. For example, when the ambient temperature range to which the ambient temperature belongs is _Te >20°C, the target setting temperature is determined to be _Te >20°C.

In some embodiments, before controlling the water heater to heat according to the target set temperature and target working mode, the relative distance between the user and the water heater is determined, and the water heater is controlled to perform at least one of the following operations according to the relative distance: shutdown and startup. If the water heater is controlled to be turned on, the heating of the water heater is controlled according to the water heater control method provided in any of the above embodiments. Therefore, the control convenience of shutdown, startup and heating of the water heater is improved, and the intelligence of the water heater is improved.

In the process of determining the relative distance between the user and the water heater, a possible implementation method includes: acquiring the latitude and longitude of the location of the user; acquiring the latitude and longitude of the location of the water heater; The relative distance of the water heater. Therefore, based on the latitude and longitude positioning, the accuracy of the relative distance between the user and the water heater is improved.

The latitude and longitude of the location of the user is determined by determining the latitude and longitude of the location of the user terminal bound to the water heater. For example, the water heater is bound to the user's mobile phone, and the latitude and longitude of the location of the mobile phone can be determined through the positioning sensor on the mobile phone, and then the latitude and longitude of the user's location can be obtained. A positioning sensor is also installed on the water heater, and the latitude and longitude of the location where the water heater is located is obtained through the positioning sensor.

Among them, based on the longitude and latitude of the user's location and the longitude and latitude of the location of the water heater, the relative distance between the user and the water heater can be calculated by using the haversine formula. The calculation formula is expressed as:

表示用户所在位置的维度、热水器所在位置的维度、Δλ表示用户所在位置与热水器所在位置的经度差值，d表示计算得到的相对距离。Among them, R is the radius of the earth, the average value can be taken, such as 6371km,

Represents the dimension of the user's location, the dimension of the location of the water heater, Δλ represents the longitude difference between the location of the user and the location of the water heater, and d represents the calculated relative distance.

Optionally, controlling the water heater based on the relative distance between the user and the water heater includes at least one of the following:

1) If the relative distance gradually increases, and the duration of the relative distance greater than or equal to the first distance is greater than the first duration, it is considered that the user is away from home, and the water heater is controlled to turn off.

For example, if D increases gradually, and Z ₁ minute keeps D≥X ₁ , the server sends a shutdown instruction to the water heater to control the water heater to shut down, where D is the relative distance, Z ₁ is the first duration, and X ₁ is the first distance , for example, Z ₁ is 5, and X ₁ is, for example, 1000.

2) If the relative distance gradually decreases, and the duration of the relative distance less than or equal to the second distance is greater than the second duration, it is considered that the user is at home and gradually approaches the water heater, and the water heater is controlled to be turned on. After starting up, control the water heater to heat according to the target set temperature and target working mode.

For example, if D gradually decreases, and D≤X ₂ is maintained for Z ₂ minutes, the server sends a power-on command to the water heater to control the water heater to shut down, where Z ₂ is the first duration, X ₂ is the first distance, and Z ₂ is, for example, 5, X ₂ is 200, for example.

3) If the relative distance gradually decreases and then gradually increases, and there is a relative distance greater than the first distance in the change process, and the time when the relative distance is greater than the first distance is later than the time when the relative distance is the smallest in the change process, it is determined that the user has passed by. Close to home and away from home, control the water heater to turn off.

For example, if D gradually decreases and then gradually increases, and there is a minimum value D _min , there is also a case of D ≥ X ₁ , and the time point T _time1 of D _min appears earlier than the time point T _time2 of D ≥ X ₁ , That is, if T _time2 > T _time1 , the server sends a shutdown instruction to the water heater to control the water heater to shut down.

Further, when the relative distance between the user and the water heater changes from small to large, record the relative distance between the user and the water heater when the user turns off the water heater and the length of time from when the relative distance between the user and the water heater increases from small to when the water heater is turned off. In this way, the values of the first distance and the first duration are determined from the relative distances and durations of the multiple records. For example, the mode, mean or median of multiple relative distances between the user and the water heater when the user turns off the water heater is determined as the first distance, and the relative distance between the user and the water heater is increased from a small to a plurality of time periods when the water heater is turned off. The mode, mean or number of central defenders is determined as the first duration.

Further, when the relative distance between the user and the water heater changes from large to small, record the relative distance between the user and the water heater when the user turns on the water heater and the length of time from when the relative distance between the user and the water heater changes from large to small until the water heater is turned on. In this way, the values of the second distance and the second duration are determined among the relative distances and durations of the multiple records. For example, the mode, mean or median of multiple relative distances between the user and the water heater when the user turns on the water heater is determined as the second distance, and the relative distance between the user and the water heater is changed from large to small to multiple durations when the water heater is turned on The mode, mean, or number of central defenders in , is determined as the second duration.

Further, through the real-time collection and recording of data, the first distance, the second distance, the first duration, and the second duration can be updated in time to improve the accuracy of the first distance, the second distance, the first duration, and the second duration. Thus, the accuracy of water heater control is improved.
