Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.
Any number of elements in the figures are for illustration and not limitation, and any naming is used for distinction only and not for any limiting sense.
In recent years, with the improvement of living standard of people, people pay more attention to comfort of indoor air environment. Therefore, how to control the indoor air environment comfort is important to meet the indoor air environment expected by the user.
In the related art, an indoor air environment comfort level control method is generally based on indoor air environment single parameter monitoring, for example, a data acquisition device such as a temperature sensor and a humidity sensor is used for acquiring an air environment value, the acquired air environment value is calculated to obtain the comfort level of the current environment, and the indoor air environment is adjusted according to the environment comfort level.
However, the metabolic rate of the human body is an important index for evaluating the comfort of the current environment, and when the human body is in different activity states, the human body has different comfort feelings on the same environment, so that when the comfort evaluation or control is performed, if the actual metabolic level of the user is not considered, the actual feeling of the current user is difficult to obtain; if the comfort experience of the user in the current environment cannot be accurately obtained, the air environment cannot be controlled to meet the requirement of the user; for example, when a user moves indoors, the metabolic quantity is increased, the heart rate of the user is reflected to be increased, and at the same time, the user can feel that the current environment is hot in the same air environment, so that uncomfortable experience is brought, and the traditional control method can not sense the state change of the user to perform corresponding control; it follows that the actual metabolic state of the user needs to be taken into account when performing the air environment comfort adjustment.
However, the method for calculating the comfort level is calculated based on the air environment parameters, so that the calculated parameters of the comfort level are single, the calculated comfort level is inaccurate, and the adjustment of the intelligent household equipment by using the comfort level is inaccurate.
Therefore, the application provides an indoor air environment adjusting method, which is characterized in that the heart rate of a user in a room is monitored in real time, and the actual metabolism rate of the user is determined according to the heart rate of the user, so that when the comfort level is calculated, not only the environment parameters of the space in which the user is positioned are considered, but also the individual parameters of different users, such as the actual metabolism rate and body surface parameters of the user, are considered, therefore, the comfort level calculating result felt by different users is more targeted and accurate, and the accuracy of comfort level adjustment is improved.
After the design idea of the embodiment of the present application is introduced, some simple descriptions are made below for application scenarios applicable to the technical solution of the embodiment of the present application, and it should be noted that the application scenarios described below are only used for illustrating the embodiment of the present application and are not limiting. In the specific implementation, the technical scheme provided by the embodiment of the application can be flexibly applied according to actual needs.
Referring to fig. 1, fig. 1 shows an application scenario diagram of an indoor air environment conditioning method, where 11 represents an indoor air environment conditioning device, which may be a server or other terminals, and the server is taken as an example in fig. 1; the air conditioner is 12, the fresh air machine is 13, the air purifier is 14, wherein the air conditioner is temperature regulating equipment, and the fresh air machine and the air purifier are wind speed regulating equipment. After the metabolism rate of the user is considered, the comfort level felt by the user is calculated, and the intelligent household equipment corresponding to the comfort level is adjusted according to the comfort level, for example, the air conditioner is adjusted to be higher by 5 ℃.
Of course, the method provided by the embodiment of the present application is not limited to the application scenario shown in fig. 1, but may be used in other possible application scenarios, and the embodiment of the present application is not limited. The functions that can be implemented by each device in the application scenario shown in fig. 1 will be described together in the following method embodiments, which are not described in detail herein.
In order to further explain the technical solution provided by the embodiments of the present application, the following details are described with reference to the accompanying drawings and the detailed description. Although embodiments of the present application provide the method operational steps shown in the following embodiments or figures, more or fewer operational steps may be included in the method based on routine or non-inventive labor. In steps where there is logically no necessary causal relationship, the execution order of the steps is not limited to the execution order provided by the embodiments of the present application.
The technical scheme provided by the embodiment of the application is described below with reference to an application scenario shown in fig. 1.
Referring to fig. 2, an embodiment of the present application provides an indoor air environment conditioning method applied to an indoor air environment conditioning apparatus, which takes a server as an example, the indoor air environment conditioning method including at least the steps of:
S201, determining the metabolic rate of the target user based on the heart rate of the target user.
S202, determining the comfort level of the target user by applying the metabolic rate of the target user, the environmental parameters of the space where the target user is located and the body surface parameters of the target user.
S203, sending an adjusting instruction to the corresponding intelligent home equipment according to the difference between the comfort level of the target user and the preset comfort level, wherein the preset comfort level is determined according to the preset heart rate value.
In the above embodiment, since the comfort feeling of the user is related to the actual metabolic situation of the current human body, there is a certain relationship between the actual metabolic situation of the human body and the heart rate of the user, and the metabolic rates of different users may be different or the metabolic rates of the same user may be different at different times, the metabolic rate of the target user is first determined based on the heart rate of the target user; secondly, when the comfort level is determined, the body surface parameters and the metabolic rate of the target user are considered in addition to the environmental parameters of the space in which the target user is positioned, and the determined comfort level of the target user is more accurate; finally, when the intelligent household equipment is adjusted according to the difference between the comfort level of the target user and the preset comfort level, the determined comfort level of the application is more accurate, so that the intelligent household equipment is adjusted.
Referring to S201, since the heart rates of different users are not necessarily the same, the heart rates of the same user at different times are not necessarily the same, so that the heart rate of the target user in the space, which may be a room, is first obtained in the present case. For example, the heart rate of the target user measured by the millimeter wave radar sensor may be received, and the millimeter wave radar sensor may be directly placed at a certain position in the room, and may also be disposed inside a certain smart home device, for example, inside an air conditioner, and the disposed position ensures that the signal may be transmitted and received. Specifically, the millimeter radar wave sensor transmits a signal to a target user, processes a return signal, obtains the heart rate of the target user by detecting a tiny phase change caused by heart beat of the user, and uploads the heart rate to the server through a unified uploading interface. In this way, whether the heart rate of the user is increasing or decreasing, it can be obtained by the server in order to determine the metabolic rate in real time.
After receiving the heart rate of the target user, the server determines the metabolic rate of the target user. Because different heart rates can represent different states of the user, and different movement states correspond to different metabolic rates, the state of the target user is determined based on the heart rate of the target user, and then the metabolic rate of the target user is determined according to the state of the target user and the relationship between the state of the user and the metabolic rate. Illustratively, the respective states are, for example, a calm state, a slightly active state, a normally active state, a slightly moving state, and a largely moving state. In a specific example, M represents the metabolic rate, and 70bps is taken as the standard resting heart rate, and in this state, the metabolic rate of the human body takes a default value of Ms of about 58.14W/M 2 Table 1 shows the values of metabolic rates corresponding to the values of one different heart rate.
TABLE 1 values of metabolic rates corresponding to different heart rate values
| Heart rate range (bps) | User status | M takes on value |
| <80 | Quiet | 1.2Ms |
| 80-95 | Slightly movable | 1.375Ms |
| 95-110 | Normal activities | 1.55Ms |
| 110-130 | Slight movement | 1.725Ms |

Thus, after determining the heart rate of the target user, the metabolic rate thereof is determined according to the state thereof.
S202, the comfort level feeling of the user is related to the actual metabolic quantity of the current human body, and the actual metabolic quantity of the user has a certain relation with the heart rate; according to the heart rate of the user detected by the millimeter wave radar, the current metabolism level of the user is obtained, and further in order to improve the accuracy of calculating the comfort level of the target user, on one hand, the general information of the space, such as the environmental parameters of a room, is considered when the comfort level of the target user is calculated, and on the other hand, the personal information of the target user, such as the metabolism rate of the target user and the body surface parameters of the target user, is considered. The comfort level of the target user obtained in this way accords with the characteristics of the target user, and is more accurate. Therefore, it will be possible to determine whether or not control of the relevant device is required using the comfort level as a criterion.
Specifically, basic metabolism data are determined according to the metabolism rate of the target user; determining first metabolism data of a user under the environment parameters according to the metabolism rate of the target user and the environment parameters of the space where the target user is located; determining physical sign data of a user under the environmental parameters according to the body surface parameters of the target user and the environmental parameters of the target user; the application sign data and the first metabolic data adjust the underlying metabolic data to determine the comfort of the target user.
By way of example, the environmental parameters may include: vapor pressure, convective heat transfer coefficient, air temperature, radiant temperature, and the like. Body surface parameters may include: the surface temperature and the dressing coefficient of the dressing body, etc.
In a specific example, PMV (Predicted Mean Vote, average thermal sensation index) characterizes an evaluation of a human thermal response, and PMV is used to represent human comfort. The calculation formula of the comfort level is:
wherein M is a metabolic rate determined from heart rate, p a Taking a default value for the water vapor pressure; h is a c Taking a default value for the convection heat transfer coefficient; t is t a Taking an actually measured temperature value as the air temperature;taking the air temperature as a default for radiation temperature; t is t cl Taking a default value for the surface temperature of the human body; f (f) cl For the clothing coefficient, a default value is taken.
In addition, (0.303 e -0.036M +0.028) as basal metabolic data; 6.8167+0.4523.M+ 3.054.p a +0.0014·M·t a Is first metabolic data; is sign data. And (3) making a difference between the first metabolism data and the sign data, and multiplying the difference with the basic metabolism data to obtain the comfort level of the target user.
The comfort level calculated by the above formula is generally in the range of-3 to 3, and the larger the data is, the hotter the user currently experiences, and the smaller the data is, the colder the user currently experiences. The values of the default values and the constant values in the calculation formula are only examples, and are not particularly limited.
S203 is involved, the preset comfort level is obtained through calculation according to the preset heart rate value, the preset comfort level is used as a reference for judging the comfort level of the target user, and then an adjusting instruction is sent to the corresponding intelligent home equipment according to the difference between the comfort level of the target user and the preset comfort level.
Specifically, determining an adjustment strategy corresponding to a difference between the comfort level of the target user and a preset comfort level; and sending an adjusting instruction to the corresponding intelligent home equipment according to the adjusting strategy. The preset comfort level is obtained by calculating a standard quiet heart rate, and when the difference between the comfort level of the target user and the preset comfort level is greater than 0.5, the intelligent home equipment needs to be adjusted; when the difference between the comfort level of the target user and the preset comfort level is smaller than or equal to 0.5, the intelligent household equipment does not need to be adjusted, and the larger the difference is, the larger the adjusting amplitude is. In a specific example, table 2 shows the adjustment strategy for one different comfort level difference and table 3 shows the adjustment strategy for another different comfort level difference.
Table 2 adjustment strategy for different comfort level differences
| Comfort level difference range | Temperature regulation of size |
| <0.5 | -- |
| 0.5-1.0 | 1℃ |
| 1.0-1.5 | 2℃ |
| 1.5-2.0 | 3℃ |
| >2.0 | 4℃ |
TABLE 3 adjustment strategy for different comfort level differences
| Comfort level difference range | Wind speed regulation |
| <0.5 | -- |
| 0.5-1.0 | 1 st gear |

| 1.5-2.0 | 3 gear |
| >2.0 | 4 th gear |
And what strategy is selected is related to the type of smart home device in the current space and also to the adjustment capabilities of the smart home device. For example, if the smart home device includes only a temperature regulation device, such as an air conditioner, a corresponding temperature regulation policy may be determined according to table 2; if the smart home device includes only wind speed regulation devices, such as a fresh air machine or an air purifier, a corresponding wind speed regulation strategy may be determined according to table 3; if the intelligent household equipment comprises temperature adjusting equipment and wind speed adjusting equipment, the effect of temperature adjustment on comfort level is improved faster than that of wind speed adjustment, so that a temperature adjusting instruction is preferentially sent to the temperature adjusting equipment, and if comfort level adjustment can not be achieved only through temperature adjustment, the intelligent household equipment is achieved through the cooperation adjustment of the temperature adjusting equipment and the wind speed adjusting equipment.
In a specific example, fig. 3 shows a schematic diagram of a study room air environment adjustment, in which a current space is a study room, 31 is an air conditioner, a target user is a, the user a is working, an acquired heart rate of a is 78bps, it is determined that the user a is in a quiet state, a metabolic rate of the user a is 1.2Ms, and then a comfort level required by the user a in the current state is calculated to be P1, which is 0.8 higher than a preset comfort level, and a corresponding adjustment strategy is that a temperature adjustment device is lowered by 1 ℃, or a wind speed adjustment device is raised by 1. And when detecting that only an air conditioner exists in the study room, sending a temperature adjusting instruction for reducing the temperature by 1 ℃ to the air conditioner.
In another specific example, fig. 4 shows a schematic diagram of a living room air environment adjustment, in which 41 is an air conditioner, 42 is an air purifier, the current space is a living room, the target user is B, the user B is skipping a rope, the acquired heart rate of the user B is 120, it is determined that the user B is in a slight movement state, the metabolic rate is determined to be 1.725Ms, further, the comfort level required by the user B in the current state is calculated to be P2, which is 2.8 higher than the preset comfort level, and the corresponding adjustment strategy is that the temperature adjustment device is reduced by 4 ℃ or the wind speed adjustment device is increased by 4. And detect that there is the existing air conditioner in the living room, also have the air purifier, then can judge at this moment to reduce 4 ℃ and be the requirement that satisfies the temperature limit value of air conditioner, if, then directly reduce 4 ℃ with the air conditioner, otherwise, still need the air purifier cooperation to realize the regulation to the comfort level.
In the practical application process, the air conditioner or the fresh air fan is matched in the adjustment process due to the temperature limit value of the air conditioner, or the air conditioner and the air purifier are matched. In the following, a specific example will be used to describe the case, and if the temperature adjustment range represented by the temperature adjustment instruction in the adjustment instruction exceeds the temperature limit value of the temperature adjustment device, the temperature adjustment instruction is updated according to the temperature limit value, and the updated temperature adjustment instruction is sent to the temperature adjustment device; and updating the wind speed regulating command in the regulating command according to the temperature limit value, and sending the updated wind speed regulating command to the wind speed regulating device. For example, the temperature regulation command is +5deg.C, the current temperature of the air conditioner is 32deg.C, and the upper temperature limit of the air conditioner is 35 deg.C, so that the temperature regulation command cannot be realized at this time, the temperature regulation command is updated to +3deg.C, and thus the comfort requirement of the user cannot be met, at this time, the wind speed regulation command is regulated to meet the comfort requirement of the user, for example, after the temperature regulation command is updated to +3deg.C, the wind speed of the fresh air blower or the air purifier is +2, and thus the comfort regulation is realized by the cooperation of the air conditioner and the fresh air blower, or the cooperation of the air conditioner and the air purifier.
In addition, in the practical application process, in order to improve the feeling of the user, after the intelligent home equipment sends the adjusting instruction to the corresponding intelligent home equipment, the intelligent home equipment sends the adjusting feedback instruction to the server after adjusting according to the adjusting instruction, the adjusting feedback instruction characterizes that the adjusting operation is finished, at this time, the heart rate of the target user is detected, if the difference value between the heart rate of the target user and the preset heart rate is within the set heart rate difference value range, the comfort level felt by the user at this time meets the requirement of the user, at this time, the intelligent home equipment is controlled to operate according to the set parameters, wherein the set parameters can be the operation parameters of the intelligent home equipment which are corresponding to the preset heart rate, namely, the determined comfort level under the preset heart rate is matched.
In order to enable a user to know the running state and the adjusting state of the intelligent home equipment in time, the intelligent mobile phone of the user can be respectively connected with the indoor air environment adjusting equipment and the intelligent home equipment, so that the intelligent home equipment can send the current running state of the intelligent home equipment, such as the current temperature of an air conditioner, to the intelligent mobile phone of the user, the indoor air environment adjusting equipment can send the current comfort level and an adjusting instruction to the intelligent mobile phone of the user, and the adjusting instruction is used for the user to know the adjusting operation. In addition, the smart phone may also receive a prompt message such as an adjustment result, and the form of the received message may be that of receiving through APP (Application).
In a specific example, fig. 5 shows a display page diagram of an intelligent terminal, in this example, both the current data and the adjustment mode are displayed on the display page of the intelligent terminal, so that the user can learn in time. The current data is, for example, the current heart rate of 120bps, the current state is a slight exercise, the determined comfort level is 2.5, and the corresponding adjustment mode is +1℃.
