In some embodiments, the smart home system includes the control device of the linked fresh air device provided in the foregoing embodiments.

The control method and device for the linkage fresh air device and the intelligent home system provided by the embodiment of the application can realize the following technical effects:

for two rooms with air flow, in a scene that the two rooms are heated or cooled simultaneously, and the air introduced into the two rooms from the outside has promotion effect on the heating process or cooling process of the two rooms, the indoor temperatures of the two rooms can appear in the following three conditions: first case: the difference between the current first indoor temperature of the first room and the set temperature is larger, and the difference between the current second indoor temperature of the second room and the set temperature is larger; second case: the difference between the current first indoor temperature of the first room and the set temperature is smaller, and the difference between the current second indoor temperature of the second room and the set temperature is larger; third case: the difference between the current first indoor temperature of the first room and the set temperature is smaller, and the difference between the current second indoor temperature of the second room and the set temperature is smaller.

In the technical scheme of the application, the temperature difference between the first indoor temperature and the outdoor temperature of the first room and the interference of the fresh air rate of the first fresh air device on the indoor temperature are unified to be a temperature promotion coefficient, and the current first temperature difference between the current first indoor temperature and the current first temperature difference between the current first indoor temperature and the set temperature are positively correlated with a target temperature promotion coefficient.

In the first case, the temperature difference between the current first indoor temperature and the set temperature is larger, the target temperature promotion coefficient is larger, more outdoor air can be introduced into the first room, the first fresh air device sucks the outdoor air into the first room, part of the air in the first room seeps out to the outside through a gap of the first room, the other part of the air in the first room flows into the second room, and for the first room, more outdoor air extrudes the original air in the first room out of the first room, so that the temperature difference between the current first indoor temperature and the set temperature can be reduced faster; the pressure of the first room is larger than that of the second room, the air in the first room flows into the second room, the second fresh air device also sucks the outdoor air into the second room, the air in the second room seeps out to the outside through a gap of the second room, and the original air in the second room is extruded to the outside by utilizing the air flowing into the second room in the first room and the air sucked into the second room from the outside, so that the temperature of the second room can be raised relatively quickly.

The second condition indicates that the current first indoor temperature is close to the set temperature and the temperature difference between the current second indoor temperature and the set temperature is larger, and because the current first temperature difference is smaller, the target temperature promotion coefficient is smaller, the first fresh air device has smaller interference to the temperature of the first room from the air sucked into the first room outdoors, namely, other interference is smaller in a temperature regulation system formed by a temperature regulation device of the first room and the first room, so that the fluctuation time period from the first indoor temperature of the first room to the set temperature is shortened, and the current first indoor temperature is relatively fast stabilized at the set temperature; the second pressure of the second room is smaller than the first pressure of the first room, interference to the temperature stabilizing process of the first room caused by the fact that air in the second room flows into the first room can be avoided, and the second fresh air device of the second room can suck as much outdoor air into the second room as possible under the condition that the second pressure is smaller than or equal to the first pressure, so that the temperature changing process of the second room is promoted, the temperature changing speed of the second room is improved, and the temperature difference between the current second indoor temperature and the set temperature is reduced as soon as possible.

The third condition represents the condition that the current first indoor temperature and the current second indoor temperature are close to the set temperature, and because the current first temperature difference value is smaller, the target temperature promotion coefficient is smaller, and the fluctuation time from the first indoor temperature of the first room to the set temperature to the stable temperature can be shortened; under the condition that the target temperature promotion coefficient is smaller, the target first fresh air rate of the first fresh air device is not too large, so that the second pressure of the second room is smaller than or equal to the pressure of the first room, and the target second fresh air rate is not too large, therefore, the influence of the air sucked into the second room from the outside of the second fresh air device on the temperature change process of the second room is also small, the time that the second indoor temperature of the second room reaches the set temperature for the first time is shortened until the second indoor temperature is stabilized at the set temperature, and the current second indoor temperature is relatively quickly stabilized at the set temperature.

In summary, the technical scheme provided by the embodiment of the application can enable the indoor temperatures of two rooms to reach the set temperature relatively quickly and stably.

The current first indoor temperature of the current first room is greater than the current second indoor temperature of the second room, and the current first indoor temperature and the current second indoor temperature are both greater than the current outdoor temperature and the set temperature, which means that the first room and the second room are heated simultaneously, and the outdoor temperature is favorable for the condition that the first room and the second room are heated, for example, in the midday of the late autumn and early winter, the indoor temperature is lower, and the outdoor temperature is higher than the indoor temperature; the condition that the current first indoor temperature of the first room is smaller than the current second indoor temperature of the second room, and the current first indoor temperature and the current second indoor temperature are both smaller than the current outdoor temperature and the set temperature means that the first room and the second room are cooled simultaneously, and the outdoor temperature is favorable for the condition that the first room and the second room are cooled, such as a kitchen, a bathroom and the like, after the indoor temperature is higher, and the outdoor temperature is lower than the higher indoor temperature. The control method of the linkage fresh air device provided by the embodiment of the application is suitable for being adopted under the two conditions.

The control method of the linkage fresh air device can be executed through a server of the intelligent home system, and can also be executed through a controller of the fresh air device. In the environment where the control method is implemented, a first fresh air device is arranged in a first room, a second fresh air device is arranged in a second room, air flow exists between the first room and the second room, and the control method is implemented along with the temperature regulation process of the first room and the second room.

Referring to fig. 2, the control method of the linkage fresh air device includes:

s201, obtaining a current first indoor temperature of the first room, a current second indoor temperature of the second room, set temperatures of the first room and the second room, and a current outdoor temperature of the outdoor environment.

The set temperature is the set temperature of the temperature adjusting device of the first room and the second room. The execution process of the control method of the linkage fresh air device is accompanied with the temperature regulation process of the temperature regulation device on the first room and the second room. The temperature adjustment process refers to: a process of adjusting the temperature of the first room from the current first indoor temperature to the set temperature, and a process of adjusting the temperature of the second room from the current second indoor temperature to the set temperature. The control algorithm for the temperature regulation process may be a proportional-integral-derivative (Proportional Integral Derivative, PID) control algorithm, or may be a linear quadratic (Linear Quadratic Regulator, LQR) control algorithm.

The current first indoor temperature may be obtained by a first temperature sensor of the first room, which may be provided independently, may be provided on the first fresh air device, and may also be provided on the air conditioner in case the first fresh air device and the air conditioner are independent devices, respectively.

The current second indoor temperature can be obtained through a second temperature sensor of the second room, the second temperature sensor can be independently arranged and can be arranged on the second fresh air device, and the second temperature sensor can also be arranged on the air conditioner under the condition that the second fresh air device and the air conditioner are independent devices respectively.

The set temperature can be set by the user by himself, and the set temperature can be recommended by adopting the existing healthy temperature recommendation algorithm. The first room and the second room adopt the same set temperature, so that when a user moves between the first room and the second room, the temperature difference of the user can be reduced, and the temperature comfort experience of the user is improved.

Under the heating condition, the temperature regulating device can be heating equipment such as an air conditioner, an electric heater, electric hot air and the like.

In addition, the air conditioner in the embodiment of the application can be a multi-split air conditioner, a split air conditioner or a central air conditioner. The split type air conditioner is characterized in that one outdoor unit corresponds to one indoor unit.

S202, obtaining a current first temperature difference value between the current first indoor temperature and the set temperature and a current second temperature difference value between the current first indoor temperature and the set temperature when the current first indoor temperature is larger than the current second indoor temperature and the current first indoor temperature is smaller than the current outdoor temperature and the set temperature or when the current first indoor temperature is smaller than the current second indoor temperature and the current first indoor temperature is larger than the current outdoor temperature and the set temperature.

Under the condition that the current first indoor temperature is larger than the current second indoor temperature and the current first indoor temperature is smaller than the current outdoor temperature and the set temperature, the first fresh air device of the first room has a promotion effect on the temperature change process of the first room by sucking air (fresh air) of the first room outdoors, the second fresh air device of the second room has a promotion effect on the temperature change process of the second room by sucking air (fresh air) of the second room outdoors, and the air flowing to the second room from the first room has a promotion effect on the temperature change process of the second room.

In addition, when the current first indoor temperature is smaller than the current second indoor temperature and the current first indoor temperature is larger than the current outdoor temperature and the set temperature, the air sucked into the first room by the outdoor of the first fresh air device has an accelerating effect on the temperature change process of the first room, the air sucked into the second room by the outdoor of the second fresh air device has an accelerating effect on the temperature change process of the second room, and the air flowing into the second room by the first room has an accelerating effect on the temperature change process of the second room.

In the case where the current first indoor temperature is greater than the current second indoor temperature and the current first indoor temperature is less than the current outdoor temperature and the set temperature, the current outdoor temperature may be greater than the set temperature or the current outdoor temperature may be less than or equal to the set temperature. If the current outdoor temperature is greater than the set temperature, the control method of the linkage fresh air device provided by the embodiment of the application can be continuously executed until the indoor temperatures of the first room and the second room are both stable at the set temperature. If the current outdoor temperature is less than or equal to the set temperature, the control method of the linkage fresh air device provided by the embodiment of the application can be continuously executed until the current first indoor temperature is greater than or equal to the current outdoor temperature.

In addition, in the case where the current first indoor temperature is smaller than the current second indoor temperature and the current first indoor temperature is greater than the current outdoor temperature and the set temperature, the current outdoor temperature may be smaller than the set temperature, or the current outdoor temperature may be greater than or equal to the set temperature. If the current outdoor temperature is smaller than the set temperature, the control method of the linkage fresh air device provided by the embodiment of the application can be continuously executed until the indoor temperatures of the first room and the second room are both stable at the set temperature. If the current outdoor temperature is greater than or equal to the set temperature, the control method of the linkage fresh air device provided by the embodiment of the application can be continuously executed until the current first indoor temperature is less than or equal to the current outdoor temperature.

S203, determining a target temperature promotion coefficient corresponding to the current first temperature difference according to the corresponding relation between the temperature difference and the temperature promotion coefficient.

The temperature promotion coefficient is used for representing the promotion effect of a temperature difference between a first indoor temperature and an outdoor temperature of the first room and a first fresh air rate of the first fresh air device on a temperature change process of the first room.

The temperature promotion coefficient may be: an amount of change in temperature of the first room caused by air introduced from outside the room to the first room for a unit time period; or the unit time length of the air introduced from the outside to the first room is the heat or cold carried by the first room relative to the current indoor temperature.

The heat carried by the air introduced outdoors into the first room with respect to the current first indoor temperature per unit length of time is specifically: the unit time length is the heat which can be released when the air which is introduced into the first room outdoors is cooled to the current first indoor temperature; the amount of cold carried by the air introduced outdoors into the first room with respect to the current first indoor temperature per unit length of time is specifically: the unit time is the amount of heat that needs to be absorbed by the air that is introduced outdoors into the first room to heat up to the current indoor temperature.

The positive correlation between the temperature difference and the temperature promotion coefficient can be stored in a database in a one-to-one correspondence data table, and after the current first temperature difference is obtained, the target temperature promotion coefficient corresponding to the current first temperature difference can be obtained by querying the database.

Alternatively, the positive correlation between the temperature difference and the temperature promotion coefficient may be stored in advance in the form of a formula, and after the current first temperature difference is obtained, the current first temperature difference is substituted into the prestored formula, so that the target temperature promotion coefficient corresponding to the current first temperature difference may be obtained.

S204, determining a target first new wind speed corresponding to the current second temperature difference value and the target temperature promotion coefficient according to the corresponding relation among the temperature difference value, the fresh wind speed and the temperature promotion coefficient.

The fresh air rate is inversely related to the temperature difference value, and under the condition that the temperature promotion coefficient is unchanged, the larger the temperature difference value is, the smaller the fresh air rate is, and the larger the fresh air rate is; the fresh air rate is positively correlated with the temperature promotion coefficient, and under the condition that the temperature difference value is unchanged, the larger the temperature promotion coefficient is, the larger the fresh air rate is, the smaller the temperature promotion coefficient is, and the smaller the fresh air rate is; the temperature difference value is positively correlated with the temperature promotion coefficient, and under the condition that the fresh air rate is unchanged, the larger the temperature promotion coefficient is, the larger the temperature difference value is, the smaller the temperature promotion coefficient is, and the smaller the temperature difference value is.

The corresponding relation among the temperature difference value, the fresh air speed and the temperature promotion coefficient can be stored in a database in a one-to-one correspondence data table, and after the current second temperature difference value and the target temperature promotion coefficient are obtained, the target first new wind speed corresponding to the current second temperature difference value and the target temperature promotion coefficient can be obtained by inquiring the database.

Or, the corresponding relation among the temperature difference value, the fresh air speed and the temperature promotion coefficient can be stored in a database in a one-to-one correspondence data table, and after the current second temperature difference value and the target temperature promotion coefficient are obtained, the current second temperature difference value and the target temperature promotion coefficient are substituted into the prestored formula, so that the target first new wind speed corresponding to the current second temperature difference value and the target temperature promotion coefficient can be obtained.

S205, determining a target second fresh air rate according to the target first fresh air rate, so that the first pressure of the first room is greater than or equal to the second pressure of the second room.

The first pressure of the first room and the first new wind speed of the first new wind device have a first positive correlation, and after determining the target first new wind speed, a target first pressure corresponding to the target first new wind speed may be determined based on the first positive correlation. The second pressure of the second room and the second fresh air rate of the second fresh air device have a second positive correlation, a pressure value smaller than the target first pressure is taken as the target second pressure, and the target second fresh air rate corresponding to the target second pressure is determined based on the second positive correlation. In determining the target second pressure, the target second pressure is required to be greater than the outdoor pressure, so that the second room can maintain a micro positive pressure relative to the outdoor environment.

s301, obtaining a first volume of the first room and a second volume of the second room.

S302, determining a target first fresh air rate and a target first pressure corresponding to the first volume according to the corresponding relation among the fresh air rate, the volume and the pressure.

Under the condition that the fresh air rate is unchanged, the volume and the pressure intensity have a negative correlation: the larger the volume, the smaller the pressure, the smaller the volume and the larger the pressure; under the condition of unchanged volume, the fresh air rate and the pressure intensity have positive correlation: the larger the fresh air rate is, the larger the pressure intensity is, the smaller the fresh air rate is, and the smaller the pressure intensity is; under the condition of unchanged pressure, the fresh air rate and the volume have positive correlation: the larger the volume, the larger the fresh air rate, the smaller the volume, and the smaller the fresh air rate.

Or, the corresponding relation among the fresh air rate, the volume and the pressure can be prestored in the form of a formula, and after the second volume and the target second pressure are obtained, the second volume and the target second pressure are substituted into the formula, so that the target second fresh air rate corresponding to the second volume and the target second pressure can be obtained.

For the first case: the difference between the current first indoor temperature of the first room and the set temperature is larger, and the difference between the current second indoor temperature of the second room and the set temperature is larger. The current first temperature difference value is larger, the target temperature promotion coefficient is larger, the target first new wind speed rate is larger, the target first pressure of the first room is larger, meanwhile, the preset pressure difference value inversely related to the first temperature difference value is smaller, the target second pressure of the second room is larger, the target second fresh air rate is larger, and the air promotion of the indoor temperatures of the first room and the second room is facilitated to change relatively quickly.

For the second case, the difference between the current first indoor temperature of the first room and the set temperature is smaller, and the difference between the current second indoor temperature of the second room and the set temperature is larger. The current first temperature difference value is smaller, the target temperature promotion coefficient is smaller, the target first new wind speed rate is smaller, the target first pressure of the first room is smaller, the preset pressure difference value is smaller at the moment, on one hand, the temperature interference caused by the air flowing into the first room from the second room to the first room can be avoided, and the temperature of the first room is relatively fast stabilized at the set temperature; on the other hand, the smaller preset pressure difference value can enable the second fresh air device of the second room to suck outdoor air into the second room as much as possible, so that the temperature change process of the second room is quickened under the condition that the first room is not influenced.

For the third case: the difference between the current first indoor temperature of the first room and the set temperature is smaller, and the difference between the current second indoor temperature of the second room and the set temperature is smaller. The current first temperature difference value is smaller, the target temperature promotion coefficient is smaller, the target first new wind speed rate is smaller, the target first pressure of the first room is smaller, the preset pressure difference value is larger at the moment, the target second pressure can be smaller, and the second fresh air device sucks less outdoor air into the second room; meanwhile, the preset pressure difference is larger, the proportion of the air flowing into the second room from the first room in the total inflow air maintaining the pressure of the second room (the total inflow air maintaining the positive pressure of the second room relative to the outdoor environment comprises the air sucked into the second room from the outdoor and the air flowing into the second room from the first room) can be increased, when the current first indoor temperature is larger than the current second indoor temperature, the current first indoor temperature is smaller than the set temperature and the set temperature is smaller than the current outdoor temperature, or when the current first indoor temperature is smaller than the current second indoor temperature, the current first indoor temperature is larger than the set temperature and the set temperature is larger than the current outdoor temperature, the proportion of the air flowing into the second room from the first room in the total inflow air maintaining the pressure of the second room is higher, the promotion effect of the outdoor air on the temperature change process of the second room can be reduced, and the current second indoor temperature of the second room is stable at the set temperature in a smaller fluctuation period.

s401, a first temperature difference threshold value positively correlated to the precision value of the temperature regulating device of the room is obtained, and a second temperature difference threshold value corresponding to the first temperature difference threshold value is determined.

The first temperature difference threshold is used for representing a temperature difference between an indoor temperature and a set temperature of the room, and the second temperature difference threshold is used for representing a temperature difference between the indoor temperature and an outdoor temperature of the room when the temperature difference between the indoor temperature and the set temperature of the room is the first temperature difference threshold. The second temperature difference threshold is related to the outdoor temperature, and when the first temperature difference threshold is unchanged, the outdoor temperature is different, and the second temperature difference threshold is also different. When the control method of the fresh air device provided by the embodiment of the application is executed each time, the second temperature difference threshold value can be recalculated according to the current outdoor temperature.

In general, the higher the accuracy of the temperature adjustment device, the smaller the accuracy value of the temperature adjustment device. For example, the first temperature adjusting means has a precision of ±1 ℃, the second temperature adjusting means has a precision of ±0.5 ℃, and then the second temperature adjusting means has a precision higher than the first temperature adjusting means, the first temperature adjusting means has a precision value of 1, and the second temperature adjusting means has a precision value of 0.5.

In this step, when the indoor temperature is less than the set temperature and the temperature difference between the indoor temperature and the set temperature is the first temperature difference threshold, the indoor temperature is still less than the outdoor temperature; the magnitude relation between the set temperature and the outdoor temperature is not particularly limited.

In the process of providing fresh air from the outside to the inside to improve the freshness of indoor air, the outdoor pressure is generally lower than the indoor pressure, the outdoor air is sucked into the inside by the fresh air device, and the indoor air seeps out to the outside through the room gaps due to the fact that the indoor pressure is higher than the outdoor pressure. Accordingly, a person skilled in the art can empirically set a preset minimum pressure difference between indoor and outdoor according to actual requirements.

The preset minimum pressure difference corresponds to the fresh air rate of the fresh air device. After the preset minimum pressure difference is determined, the fresh air rate corresponding to the preset minimum pressure difference can be determined.

The minimum temperature promotion coefficient has a positive correlation with the fresh air rate corresponding to the preset minimum pressure difference, and the minimum temperature promotion coefficient has a positive correlation with the preset minimum pressure difference because the fresh air rate has a positive correlation with the preset minimum pressure difference; the minimum temperature promotion coefficient has a positive correlation with the second temperature difference threshold.

Further, determining a minimum temperature promotion coefficient corresponding to the preset minimum pressure difference and the second temperature difference threshold value in the room and the outdoor may include: according to the positive correlation between the pressure difference and the fresh air rate, determining a first minimum fresh air rate corresponding to a preset minimum pressure difference; and determining the minimum temperature promotion coefficient corresponding to the current second temperature difference threshold and the first minimum fresh air rate according to the corresponding relation between the temperature difference value, the fresh air rate and the temperature promotion coefficient.

S403, obtaining a preset third temperature difference threshold value, and determining a fourth temperature difference threshold value corresponding to the third temperature difference threshold value.

The third temperature difference threshold is used for representing a temperature difference between the indoor temperature and the set temperature of the room, the third temperature difference threshold is larger than the first temperature difference threshold, and the fourth temperature difference threshold is used for representing a temperature difference between the indoor temperature and the outdoor temperature of the room when the temperature difference between the indoor temperature and the set temperature of the room is the third temperature difference threshold. When the third temperature difference threshold is unchanged, the outdoor temperature is different, and the fourth temperature difference threshold is also different. When the control method of the fresh air device provided by the embodiment of the application is executed each time, the fourth temperature difference threshold value can be recalculated according to the current outdoor temperature.

S404, determining a fourth temperature difference threshold and a maximum temperature promotion coefficient corresponding to the maximum fresh air rate of the fresh air device.

The maximum temperature promotion coefficient has a positive correlation with the fourth temperature difference threshold, and the maximum temperature promotion coefficient has a positive correlation with the maximum fresh air rate of the fresh air device.

Further, the fourth temperature difference threshold and the maximum temperature promotion coefficient corresponding to the maximum fresh air rate of the fresh air device may be determined as follows: and determining the maximum temperature promotion coefficient corresponding to the fourth temperature difference threshold and the maximum fresh air rate according to the corresponding relation among the temperature difference value, the fresh air rate and the temperature promotion coefficient.

S405, establishing a first mapping relation between a first temperature difference threshold and a minimum temperature promotion coefficient.

S406, establishing a second mapping relation between the third temperature difference threshold and the maximum temperature promotion coefficient.

S407, determining a positive correlation relation between the temperature difference and the temperature promotion coefficient according to the first mapping relation and the second mapping relation.

For example, according to the first mapping relation and the second mapping relation, formula fitting is performed on the relation between the temperature difference value and the promotion coefficient so as to obtain a positive correlation relation between the temperature difference value and the promotion coefficient. Or, the neural network is utilized to learn the sample data comprising the first mapping relation and the second mapping relation, so that the neural network can output the temperature promotion coefficient corresponding to the temperature difference value.

Specifically, in determining the positive correlation between the temperature difference and the temperature promotion coefficient, in addition to the first mapping and the second mapping, a person skilled in the art may also take the temperature difference between the first temperature difference threshold and the third temperature difference threshold, and other temperature promotion coefficients between the minimum temperature promotion coefficient and the maximum temperature promotion coefficient, to form an additional mapping, and determine the positive correlation between the temperature difference and the temperature promotion coefficient by using the additional mapping.
