TECHNICAL FIELD

[0002] At present, the application of environmental intelligent regulation technology is more and more extensive, especially in the field of indoor temperature control, the core purpose of which is to improve the comfort of human body through intelligent regulation of the environment; temperature regulation not only involves the overall temperature regulation of the room, but also needs to consider the distribution and specific needs of individuals in the space. Most of the existing technologies adopt a global regulation strategy, that is, through a single temperature control device, cold air of different temperatures is sent to regulate the temperature of the entire space. However, this method cannot accurately adapt to the needs of each individual, especially in large spaces, the temperature needs of different areas are quite different, and flexible adjustment cannot be achieved.

[0003] The existing environmental regulation system usually adopts a global regulation method, regardless of whether there is a human body in the space or the number of human bodies, the system will perform consistent air supply and exhaust operation according to the set temperature; However, this method often leads to energy waste, because in the area where no one uses, the system will still regulate the temperature; At the same time, the existing system cannot accurately supply and exhaust air according to the actual position and cooling needs of a single human body when facing it; The traditional system can only regulate according to the average temperature set in the space, and cannot dynamically monitor the specific needs of the human body; In addition, these systems also lack real-time monitoring of the body surface temperature of the human body during regulation, and cannot adjust accordingly according to the temperature change of the human body.

[0004] Therefore, the present application proposes a method and system that uses cold air with a fixed temperature, performs air supply and exhaust through ventilation modules, and selects ventilation modules at different positions to regulate the temperature of the environment according to the number of human bodies, the position of the human body and the temperature of the human body.

[0087] The comparison module is used for comparing the distance and the temperature.

[0088] The present application has the following advantages:

[0089] 1、By using the ventilation module on the opposite side to regulate the temperature in the space, a more uniform cold air circulation effect can be achieved; this avoids the situation of local temperature being too high or too low caused by single direction air supply or exhaust; the opposite ventilation module can circulate the cold air by cooperation of air supply and exhaust mode, which can increase the cooling efficiency; this design can also avoid the cold air stagnating in a certain area, so as to ensure that the temperature of each part of the space can be balanced, and the overall comfort is improved.

[0090] 2、By judging the presence of human body in the space, unnecessary energy waste is avoided; when there is no human presence in the target space, no regulation and control will be carried out, which effectively saves energy, prolongs the service life of the equipment and reduces the operation cost; when there is a human in the space, the system will start the regulation and control function to ensure that the human body is in a comfortable environment temperature; this demand-based regulation and control strategy significantly reduces energy consumption.

[0091] 3、By adjusting the regulation and control strategy according to the number of human bodies in the space, this design has high flexibility; when the number of people in the space is more than one, the system adopts global regulation and control to ensure uniform temperature distribution of the whole space; when there is only one human body, fine regulation and control strategy is adopted to focus on adjusting the temperature of the single human body; this intelligent adjustment according to the scene ensures the accuracy of regulation and control, avoids unnecessary energy waste, especially in a larger space, which can effectively prevent the waste of resources and the decline of comfort; the fine regulation and control strategy can make the single human body obtain individualized environmental comfort, further improving the comfort of human body.

[0092] 4、By dividing the target space into multiple sub-regulation spaces, the system can fine-tune the temperature control of different areas; according to the number of human bodies in the sub-space, it is judged whether to regulate the temperature of the sub-space; when there is a human in the sub-space, according to the actual temperature distribution in the sub-space, targeted regulation and control is carried out; this method not only allows the system to regulate and control according to the different needs of each sub-regulation space, but also effectively avoids the waste of resources caused by large-area air supply or exhaust; by dividing the sub-regulation space, the system can accurately regulate the air supply or exhaust according to the number of human bodies and temperature demand in different areas; this way ensures that the temperature of each sub-regulation space can meet the comfort requirement, while reducing the energy consumption of the whole space, improving the regulation and control efficiency and accuracy.

[0093] 5、In the fine control strategy, the system selects the most suitable ventilation side and exhaust side according to the position of the target human body; this design can dynamically adjust according to the position of the human body to maximize the directionality and effectiveness of the supply air and exhaust air, especially for more accurate temperature regulation of the human body; through this flexible control, the system can significantly improve the experience of individual users and prevent local areas from being too cold or too hot; compared with traditional control systems, this method can significantly reduce energy waste while maintaining human comfort.

[0094] 6、The system monitors the body surface temperature of the human body in real time and compares it with the normal body temperature of the human body to determine whether adjustment is needed; this body surface temperature-based control strategy can effectively prevent the human body from being disturbed by cold air when it is unnecessary, while ensuring timely cooling service when the body surface temperature of the human body is too high; at the same time, this method can select the appropriate ventilation module according to the actual body surface temperature of the human body; if the difference between the body surface temperature of the human body and the normal body temperature of the human body is greater than or equal to the high temperature determination threshold, it means that the human body is overheated and needs to be cooled down faster, so the ventilation module closest to the human body is selected for cooling; if the body surface temperature of the human body is less than the high temperature determination threshold, it means that the human body has a high temperature phenomenon, but the difference with the normal body temperature of the human body is not large, and rapid cooling is not needed, so the ventilation module far from the human body is selected for cooling; this way of dynamically selecting the ventilation module according to the body surface temperature of the human body maximizes the comfort of the human body and reduces the energy consumption of the system.

[0095] 7、By monitoring the change of the body surface temperature of the human body during the process of air supply and exhaust, and adjusting the ventilation module that performs air supply and exhaust according to the temperature change result; when the current temperature monitored is greater than the historical temperature, it means that the cooling effect of the current ventilation module on the human body is insufficient, so the ventilation module closer to the human body is adjusted to cool the human body; when the current temperature monitored is less than the historical temperature, it is further judged and compared with the cooling threshold; if the cooling temperature difference is equal to the cooling threshold, it means that the cooling effect meets the expected cooling requirement, and the current ventilation module is kept for cooling; if the cooling temperature difference is less than the cooling threshold, it means that the cooling effect is lower than the expected cooling requirement, so the ventilation module closer to the human body is adjusted to cool the human body; if the cooling temperature difference is greater than the cooling threshold, it means that the cooling effect is higher than the expected cooling requirement, so the ventilation module farther from the human body is adjusted to cool the human body; the advantage of this design is that the system can quickly adjust the ventilation module used when the cooling effect is not ideal to maximize the temperature regulation effect; through this dynamic adjustment, the system can restore the body surface temperature of the human body to the normal level in a short time, avoiding the phenomenon of excessive cooling or heating, and thus improving the comfort of the human body.

[0096] Figure 1 This is a schematic diagram showing the location of the ventilation module of the present invention.

[0097] Figure 2 This is a schematic diagram showing the location of the boundary line of the present invention. Detailed Implementation

[0098] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0099] Example 1: An intelligent environmental control method based on human thermal comfort, comprising:

[0100] The space that requires environmental control is designated as the target space.

[0101] By using ventilation modules positioned on opposite sides of the target space, the temperature within that space can be regulated. This method of temperature control via opposing ventilation modules achieves a more uniform airflow, preventing localized overheating or underheating that can occur with unidirectional airflow. The opposing ventilation modules, through the coordination of airflow and exhaust modes, circulate the incoming cool air, increasing cooling efficiency. This design also prevents cool air from stagnating in any one area, ensuring balanced temperature control throughout the space and enhancing overall comfort.

[0102] The ventilation module includes an air supply mode and an exhaust mode; when the ventilation module supplies air, the air velocity and air temperature are constant.

[0103] The number of human bodies in the target space is obtained through the human body count module;

[0104] If there are no human beings in the target space, no control measures are taken; by judging the presence of human beings in the space, unnecessary energy waste is avoided; when there are no human beings in the target space, no control measures are taken, which effectively saves energy, extends the service life of equipment, and reduces operating costs; when there are human beings in the space, the system will activate the control function to ensure that the human beings are in a comfortable ambient temperature; this demand-based control strategy significantly reduces energy consumption.

[0105] If the number of human bodies in the target space is greater than 1, then a global control strategy will be executed.

[0106] If the number of people in the target space is equal to 1, a micro-adjustment strategy is executed. The system adopts different adjustment strategies based on the number of people in the space, which is highly flexible. When there are more than 1 people in the space, the system uses global control to ensure uniform temperature distribution throughout the space. When there is only one person, a micro-adjustment strategy is used to focus on adjusting the temperature of that individual person. This intelligent adjustment method based on the scenario ensures the accuracy of the control and avoids unnecessary energy waste. Especially in larger spaces, it can effectively prevent resource waste and decreased comfort. The micro-adjustment strategy can provide individual people with personalized environmental comfort, further enhancing human comfort.

[0107] The global control strategy includes:

[0108] Based on the location of the ventilation module, the target space is divided into N sub-control spaces; N is a constant representing the number of sub-control spaces that the target space can be divided into. By dividing the target space into multiple sub-control spaces, the system can finely manage the temperature control of different areas. The system determines whether to adjust the temperature of a sub-space based on the number of people in it. When there are people in a sub-space, targeted adjustments are made based on the actual temperature distribution within that sub-space. This method not only allows the system to adjust according to the different needs of each sub-control space but also effectively avoids the resource waste caused by large-area air supply or exhaust. By dividing the space into sub-control spaces, the system can accurately perform directional air supply or exhaust based on the number of people and temperature requirements in different areas. This approach ensures that the temperature of each sub-control space meets comfort requirements while reducing overall energy consumption and improving control efficiency and accuracy.

[0109] Obtain the number of human bodies existing in each sub-control space, and denote it as the number of human bodies;

[0110] If the number of human beings in the sub-control space is zero, then no temperature control will be applied to the sub-control space.

[0111] If the number of people in the sub-control space is not zero, the temperature distribution in the sub-control space is obtained, and the supply air side and exhaust air side are selected according to the temperature distribution.

[0112] The aforementioned micro-adjustment strategy includes:

[0113] Record the human body existing in the target space as the target human body, and obtain the location of the human body in the target space as the target location;

[0114] The body surface temperature of the target human body is obtained through the temperature measurement module;

[0115] According to the position of the target human body, the air supply side and the air exhaust side are selected; under the fine adjustment control strategy, the system selects the most suitable air supply side and air exhaust side according to the position of the target human body; this design can dynamically adjust according to the position of the human body, ensure the directionality and effectiveness of air supply and air exhaust, and especially more accurately regulate the temperature of the human body; through this flexible control, the system can significantly improve the experience of a single user and prevent the occurrence of local overcooling or overheating; compared with traditional control systems, this method can significantly reduce energy waste while keeping the human body comfortable.

[0116] The surface temperature of the target human body is compared with the normal body temperature of the human body, and the ventilation module for performing air supply and air exhaust is selected according to the comparison result;

[0117] During the process of air supply and air exhaust performed by the ventilation module, the surface temperature change of the target human body is monitored, and the ventilation module for performing air supply and air exhaust is adjusted according to the surface temperature change.

[0118] According to the position of the ventilation module, the target space is divided into N sub-control spaces, which includes:

[0119] Referring to Figure 1 , the ventilation module is divided into two rows parallel to each other, and each row is composed of N ventilation modules arranged in a straight line; one row of ventilation modules is marked as No. 1 row, and the other row is marked as No. 2 row;

[0120] Each ventilation module in No. 1 row corresponds to one ventilation module in No. 2 row, and the two ventilation modules are arranged in opposition;

[0121] For the ventilation modules in No. 1 row, the ventilation modules are sequentially marked as X1, X2, X3, and so on to X N ;

[0122] For the ventilation modules in No. 2 row, the ventilation modules are sequentially marked as Y1, Y2, Y3, and so on to Y N ;

[0123] Referring to Figure 2 , the midpoint between X1 and X2 is obtained, and the midpoint between Y1 and Y2 is obtained, and the two midpoints are connected as a boundary line;

[0124] The midpoint between X2 and X3 is obtained, and the midpoint between Y2 and Y3 is obtained, and the two midpoints are connected as a boundary line;

[0125] The midpoint between X3 and X4 is obtained, and the midpoint between Y3 and Y4 is obtained, and the two midpoints are connected as a boundary line;

[0126] Until the midpoint between XN-1 and X N the midpoint of the distance between Y N-1 and Y N , connect the two midpoints as a dividing line;

[0127] The dividing line divides the target space into N spaces, and each divided space is a sub-control space.

[0128] If the number of people in the sub-control space is not zero, the temperature distribution in the sub-control space is obtained, and the air supply side and the air exhaust side are selected according to the temperature distribution, including:

[0129] Obtain the temperature at each position in the sub-control space and compare it;

[0130] Select the position with the highest temperature, which is called the temperature pole;

[0131] Obtain two ventilation modules in the sub-control space, and the ventilation module belonging to No. 1 row is called No. 1 module, and the ventilation module belonging to No. 2 row is called No. 2 module;

[0132] Obtain the center point of the plane covered by each ventilation module as the ventilation point of each ventilation module;

[0133] Obtain the ventilation point of No. 1 module and the ventilation point of No. 2 module respectively, and obtain the distance between each ventilation point and the temperature pole;

[0134] The distance between the ventilation point of No. 1 module and the temperature pole is called the first distance, and the distance between the ventilation point of No. 2 module and the temperature pole is called the second distance, and the first distance and the second distance are compared;

[0135] If the first distance is greater than or equal to the second distance, the No. 1 module ventilation module is used as the air supply side, and the No. 2 module is used as the air exhaust side;

[0136] If the second distance is greater than the first distance, the No. 2 module ventilation module is used as the air supply side, and the No. 1 module is used as the air exhaust side; when the ventilation module is air supply, the cold air sent in will be blown into the target space at a certain speed, which will cause the cold air to gather in the position far away from the air supply. Therefore, the ventilation module far away from the temperature pole is selected as the air supply side;

[0137] Control the ventilation module of the air supply side to be in the air supply mode and send cold air into the sub-control space, and control the ventilation module of the air exhaust side to be in the air exhaust mode and exhaust air from the sub-control space.

[0138] The air supply side and the air exhaust side are selected according to the position of the target human body, including:

[0139] Draw a first straight line at the position of the first row, so that the first straight line passes through each ventilation module in the first row;

[0140] Draw a second straight line at the position of the second row, so that the second straight line passes through each ventilation module in the second row;

[0141] Record the position of the target human body as a target position;

[0142] Obtain the vertical distance between the target position and the first straight line, and record it as a first distance;

[0143] Obtain the vertical distance between the target position and the second straight line, and record it as a second distance;

[0144] Compare the first distance and the second distance;

[0145] If the first distance is greater than or equal to the second distance, select the first row as the air supply side and the second row as the air exhaust side;

[0146] If the first distance is less than the second distance, select the second row as the air supply side and the first row as the air exhaust side; when the ventilation module supplies air, the cold air supplied will converge at a position far from the air supply ventilation module, so the ventilation module far from the target position is selected as the air supply side.

[0147] The comparison of the body surface temperature of the target human body with the normal body temperature of the human body and the selection of the ventilation module for performing air supply and air exhaust according to the comparison result, comprises:

[0148] Obtain the distance between each ventilation module in the air exhaust side and the target position, and record it as an air exhaust distance;

[0149] Obtain the ventilation module corresponding to the minimum air exhaust distance, and record it as an air exhaust ventilation module;

[0150] Obtain the distance between each ventilation module in the air supply side and the target position, and record it as an air supply distance;

[0151] Obtain the ventilation module corresponding to the maximum air supply distance, and record it as a far-end ventilation module;

[0152] Obtain the ventilation module corresponding to the minimum air supply distance, and record it as a near-end ventilation module;

[0153] Set a high temperature determination threshold; the high temperature determination threshold is used to determine whether the temperature of the target human body is too high, and further determine whether the target human body needs to be rapidly cooled;

[0154] If the body surface temperature of the target human body is less than or equal to the normal body temperature of the human body, it means that the target human body does not need to be cooled, and no regulation and control is performed;

[0155] If the body surface temperature of the target human body is greater than the normal human body temperature, it indicates that the target human body needs to be cooled down, and the difference between the body surface temperature of the target human body and the normal human body temperature is obtained, denoted as temperature difference value;

[0156] The temperature difference value is compared with the high temperature determination threshold value;

[0157] If the temperature difference value is less than the high temperature determination threshold value, it indicates that the temperature of the target human body does not need to be cooled down substantially, and the remote ventilation module is controlled to be in the air supply mode to perform air supply, and the exhaust ventilation module is controlled to be in the air exhaust mode to perform air exhaust;

[0158] If the temperature difference value is greater than or equal to the high temperature determination threshold value, it indicates that the temperature of the target human body needs to be cooled down substantially, and the near-end ventilation module is controlled to be in the air supply mode to perform air supply, and the exhaust ventilation module is controlled to be in the air exhaust mode to perform air exhaust; the system compares the body surface temperature of the human body with the normal human body temperature in real time to determine whether adjustment is needed; this temperature-based control strategy can effectively prevent the human body from being disturbed by cold air when it is unnecessary, while ensuring that timely cooling service is provided when the body surface temperature of the human body is too high; at the same time, this method can select appropriate ventilation modules according to the actual body surface temperature of the human body; if the difference between the body surface temperature of the human body and the normal human body temperature is greater than or equal to the high temperature determination threshold value, it indicates that the human body is overheated at this time and needs to be cooled down faster, and the ventilation module closest to the human body is selected for cooling; if the body surface temperature of the human body is less than the high temperature determination threshold value, it indicates that the human body has a high temperature at this time, but the difference between the body surface temperature and the normal human body temperature is not large, and rapid cooling is not needed, and the ventilation module far from the human body is selected for cooling; this way of dynamically selecting ventilation modules according to the body surface temperature of the human body maximizes the comfort of the human body and reduces the energy consumption of the system.

[0159] In the process of performing air supply and air exhaust by the ventilation module, the change of the body surface temperature of the target human body is monitored, and the ventilation module performing air supply and air exhaust is adjusted according to the change of the body surface temperature, comprising:

[0160] A unit time is set; the unit time is a fixed time period, which can be adaptively adjusted as needed;

[0161] A cooling threshold value is set; the cooling threshold value is a set standard of reduced temperature, which refers to the value of the reduced temperature after a unit time; if the reduced temperature after a unit time is less than the cooling threshold value, it is determined that the cooling standard has not been reached, and if the reduced temperature is greater than or equal to the cooling threshold value, it is determined that the cooling standard has been reached;

[0162] At the end of each unit time after starting air supply:

[0163] The body surface temperature of the target human body is obtained, denoted as current temperature;

[0164] The body surface temperature of the target human body obtained in the previous unit time is recorded as a historical temperature;

[0165] The current temperature is compared with the historical temperature;

[0166] If the current temperature is greater than or equal to the historical temperature, it indicates that the cooling effect on the target human body is insufficient, the ventilation module currently in the air supply mode is obtained, the ventilation module is controlled to be closed, and the ventilation module belonging to the air supply side and adjacent to the ventilation module and close to the target human body is obtained, recorded as a first adjustment ventilation module, and the first adjustment ventilation module is controlled to be in the air supply mode to perform air supply; after adjusting the air supply using the ventilation module close to the target human body, the wind speed at the position of the target human body is increased, and the cooling efficiency is thus accelerated;

[0167] If the current temperature is less than the historical temperature, it indicates that the cooling effect on the target human body is effective, the difference between the current temperature and the historical temperature is obtained, recorded as a cooling difference, and the cooling difference is compared with a cooling threshold.

[0168] The comparison of the cooling difference with the cooling threshold includes:

[0169] If the cooling difference is equal to the cooling threshold, it indicates that the cooling effect meets the expected requirement, and no adjustment is made;

[0170] If the cooling difference is less than the cooling threshold, it indicates that the cooling effect is lower than the expected cooling requirement, the ventilation module currently in the air supply mode is obtained, the ventilation module is controlled to be closed, and the ventilation module belonging to the air supply side and adjacent to the ventilation module and close to the target human body is obtained, recorded as a second adjustment ventilation module, and the second adjustment ventilation module is controlled to be in the air supply mode to perform air supply; after adjusting the air supply using the ventilation module close to the target human body, the wind speed at the position of the target human body is increased, and the cooling efficiency is thus accelerated;

[0171] If the temperature difference is greater than the temperature threshold, it means that the cooling effect is higher than the expected cooling requirement. Then, the system obtains the ventilation module in the current air supply mode, controls the ventilation module to close, and obtains the ventilation module that is also in the air supply side and adjacent to the ventilation module, and is far away from the target human body, which is recorded as the third adjustment ventilation module. The third adjustment ventilation module is controlled to be in the air supply mode to perform air supply. After adjusting the air supply using the ventilation module far away from the target human body, the wind speed at the position of the target human body is reduced, and the cooling efficiency is slowed down. By monitoring the change of the body surface temperature of the human body during air supply and air exhaust, the ventilation module performing air supply and air exhaust is adjusted according to the temperature change result. When the monitored current temperature is greater than the historical temperature, it means that the cooling effect of the current ventilation module on the human body is insufficient, and the ventilation module close to the human body is adjusted to cool the human body. When the monitored current temperature is less than the historical temperature, it is further judged and compared with the temperature difference and the temperature threshold. If the temperature difference is equal to the temperature threshold, it means that the cooling effect meets the expected cooling requirement, and the current ventilation module is kept to cool. If the temperature difference is less than the temperature threshold, it means that the cooling effect is lower than the expected cooling requirement, and the cooling efficiency needs to be improved. The ventilation module close to the human body is adjusted to cool the human body. If the temperature difference is greater than the temperature threshold, it means that the cooling effect is higher than the expected cooling requirement, and the cooling efficiency needs to be reduced. The ventilation module far away from the human body is adjusted to cool the human body. The advantage of this design is that the system can quickly adjust the ventilation module when the cooling effect is not ideal, to maximize the effect of temperature regulation. Through this dynamic adjustment, the system can restore the body surface temperature of the human body to the normal level in a short time, avoid the phenomenon of excessive cooling or heating, and improve the comfort of the human body.
