Description

Technical Field

[0001] The present invention relates to the technical field of intelligent environmental control, and in particular to an intelligent environmental control system and method based on human thermal comfort. Background Art

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

[0003] Existing environmental control systems usually adopt a global control method. Regardless of whether there are human bodies in the space or how many human bodies there are, the system will perform consistent air supply and exhaust operations according to the set temperature. However, this method often leads to energy waste because the system will still perform temperature control in unused areas. At the same time, when facing a single human body, the existing system cannot accurately supply and exhaust air according to its actual position and cooling needs. Traditional systems can often only be adjusted 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 human body surface temperature during the control process, and cannot make corresponding adjustments based on changes in human body temperature.

[0004] To this end, this solution proposes a method and system that uses cold air with a constant temperature to supply and exhaust air through ventilation modules, and selects ventilation modules at different positions to regulate the ambient temperature according to the number, position and temperature of human bodies.

[0086] Distance measurement module: used to obtain the distance between the ventilation point and the temperature extreme point, No. 1 distance, No. 2 distance, exhaust distance, and supply distance;

[0087] Comparison module: used to compare distance and temperature.

[0088] The present invention has the following beneficial effects:

[0089] 1. By using ventilation modules on opposite sides to control the temperature in the space, a more uniform circulation of cold air can be achieved. This avoids the situation where the local temperature is too high or too low due to single-direction air supply or exhaust. The ventilation modules that are opposite to each other can circulate the cold air through the coordination of the air supply and exhaust modes, which can increase the cooling efficiency. This design can also prevent the cold air from being trapped in a certain area, thereby ensuring that the temperature in various places in the space can be evenly controlled and improve the overall comfort.

[0090] 2. Avoid unnecessary energy waste by judging the presence of human bodies in the space. When there is no one in the target space, no regulation will be performed, which effectively saves energy, extends the service life of the equipment, and reduces operating costs. When there are people in the space, the system will start the regulation function to ensure that the human body is in a comfortable ambient temperature. This demand-based regulation strategy significantly reduces energy consumption.

[0091] 3. The system will adopt different control strategies according to the number of people in the space. This design is highly flexible. When the number of people in the space is greater than 1, the system adopts global control to ensure uniform temperature distribution in the entire space. When there is only one person, a micro-control strategy is adopted to focus on adjusting the temperature of a single person. This intelligent adjustment method based on the scene ensures the accuracy of the control and avoids unnecessary energy waste, especially in larger spaces. It can effectively prevent resource waste and reduced comfort. The micro-control strategy enables a single person to obtain personalized environmental comfort and further enhance human comfort.

[0092] 4. By dividing the target space into multiple sub-control spaces, the system can finely manage the temperature control of different areas; determine whether to perform temperature control on the sub-space based on the number of people in the sub-space; when there are people in the sub-space, perform targeted control based on the actual temperature distribution in the sub-space; this method not only allows the system to perform control according to the different needs of each sub-control space, but also effectively avoids the waste of resources caused by large-area air supply or exhaust; by dividing the sub-control space, the system can accurately perform directional air supply or exhaust based on the number of people and temperature requirements in different areas; this method ensures that the temperature of each sub-control space can meet the comfort requirements, while reducing the energy consumption of the entire space and improving the control efficiency and accuracy.

[0093] 5. Under the micro-control strategy, the system selects the most suitable ventilation side and exhaust side according to the location of the target human body; this design can be dynamically adjusted according to the location of the human body to ensure the maximum directionality and effect of air supply and exhaust, especially more precise temperature regulation for the human body; through this flexible control, the system can significantly improve the experience of individual users and prevent local areas from being overcooled or overheated; compared with traditional control systems, this method can significantly reduce energy waste while maintaining human comfort.

[0094] 6. The system monitors the human body surface temperature in real time and compares it with the normal body temperature to determine whether adjustment is needed. This control strategy based on body surface temperature can effectively prevent the human body from being disturbed by cold wind when it is not necessary, and ensure timely cooling service when the human body surface temperature is too high. At the same time, this method can select a suitable ventilation module according to the actual body surface temperature of the human body. If the difference between the human body surface temperature and the normal body temperature is greater than or equal to the high temperature judgment threshold, it means that the human body is overheated and needs to be cooled faster. The ventilation module closest to the human body is selected for cooling. If the human body surface temperature is less than the high temperature judgment threshold, it means that although the human body has a high temperature phenomenon, it is not much different from the normal body temperature of the human body and does not need to be cooled quickly. The ventilation module far from the human body is selected for cooling. This method of dynamically selecting ventilation modules according to the human body surface temperature maximizes the human body's comfort and reduces the energy consumption of the system.

[0095] 7. During the air supply and exhaust process, the changes in the human body surface temperature are monitored, and the ventilation module that performs air supply and exhaust is adjusted according to the temperature change results; when the current temperature monitored is greater than the historical temperature, it means that the current ventilation module has insufficient cooling effect on the human body, and the ventilation module that is closer to the human body is adjusted to cool the human body; when the current temperature monitored is lower than the historical temperature, the cooling difference 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 is consistent with the expected cooling requirements, 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, and It means that the cooling effect is lower than the expected cooling requirement and the cooling efficiency needs to be improved, then 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 and the cooling efficiency needs to be reduced, then the ventilation module farther 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 used when the cooling effect is not ideal to ensure that the temperature regulation effect is maximized; through this dynamic adjustment, the system can restore the human body surface temperature to normal levels in a shorter time, avoid excessive cooling or heating, and thereby improve the human body's comfort.

[0100] The space that needs environmental regulation is recorded as the target space;

[0101] Ventilation modules that are arranged on opposite sides and face each other are used in the target space to regulate the temperature in the target space. By using the ventilation modules on the opposite sides to regulate the temperature in the space, a more uniform cooling air circulation effect can be achieved. This avoids the situation where the local temperature is too high or too low due to air supply or exhaust in a single direction. The ventilation modules that face each other can circulate the cold air through the coordination of the air supply and exhaust modes, thereby increasing the cooling efficiency. This design can also prevent cold air from being trapped in a certain area, thereby ensuring that the temperature in various places in the space can be evenly controlled, thereby improving the overall comfort.

[0107] The global control strategy includes:

[0108] According to the location of the ventilation module, the target space is divided into N sub-control spaces; N is a constant, which represents the number of sub-control spaces into which the target space can be divided; by dividing the target space into multiple sub-control spaces, the system can finely manage the temperature control of different areas; according to the number of people in the sub-space, it is determined whether to perform temperature control on the sub-space; when there are people in the sub-space, targeted control is performed according to the actual temperature distribution in the sub-space; this method not only allows the system to perform control according to the different needs of each sub-control space, but also effectively avoids the waste of resources caused by large-area air supply or exhaust; by dividing the sub-control space, the system can accurately perform directional air supply or exhaust according to the number of people and temperature requirements in different areas; this method ensures that the temperature of each sub-control space can meet the comfort requirements, while reducing the energy consumption of the entire space and improving the control efficiency and accuracy.

[0109] Get the number of human bodies in each sub-regulation space, recorded as the number of human bodies;

[0110] If the number of people in the sub-controlled space is zero, the temperature of the sub-controlled space will not be controlled;

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

[0112] The micro-regulation strategy includes:

[0114] Obtain the target human body surface temperature through the temperature measurement module;

[0115] The air supply side and the exhaust side are selected according to the position of the target human body. Under the micro-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 be dynamically adjusted according to the position of the human body to ensure that the directionality and effect of the air supply and exhaust are maximized, especially the temperature regulation of the human body is more precise. Through this flexible control, the system can significantly improve the experience of individual users and prevent local areas from being overcooled or overheated. Compared with traditional control systems, this method can significantly reduce energy waste while maintaining human comfort.

[0116] Compare the target human body surface temperature with the normal human body temperature, and select a ventilation module for air supply and exhaust according to the comparison result;

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

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

[0119] Reference Figure 1 , the ventilation modules are divided into two parallel rows, each row is composed of N ventilation modules arranged in a straight line, one row of ventilation modules is marked as row one, and the other row is marked as row two;

[0120] Each ventilation module in row 1 corresponds to a ventilation module in row 2, and the two ventilation modules are arranged opposite to each other;

[0121] For the ventilation modules in row 1, mark the ventilation modules as X1, X2, X3, and so on according to the position sequence of the ventilation modules. N ;

[0122] For the ventilation modules in row 2, mark them as Y1, Y2, Y3, and so on according to their position order. N ;

[0123] Reference Figure 2 , get the midpoint of the distance between X1 and X2, and get the midpoint of the distance between Y1 and Y2, and connect the two midpoints as a dividing line;

[0125] Get the midpoint of the distance between X3 and X4, and get the midpoint of the distance between Y3 and Y4, and connect the two midpoints as a dividing line;

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

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

[0128] If the number of people in the sub-controlled space is not zero, the temperature distribution in the sub-controlled 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 of each position in the sub-control space and compare them;

[0130] Select the location with the highest temperature and record it as the temperature extreme point;

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

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

[0133] The ventilation points of module No. 1 and module No. 2 are obtained respectively, and the distance between each ventilation point and the temperature extreme point is obtained respectively;

[0134] Record the distance between the ventilation point and the temperature extreme point of module No. 1 as a first distance, record the distance between the ventilation point and the temperature extreme point of module No. 2 as a second distance, and compare the first distance and the second distance;

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

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

[0137] The ventilation module on the air supply side is controlled to be in the air supply mode to supply cold air into the sub-regulation space, and the ventilation module on the air exhaust side is controlled to be in the air exhaust mode to exhaust air out of the sub-regulation space.

[0138] The step of selecting the air supply side and the air exhaust side according to the position of the target human body includes:

[0139] Draw a straight line No. 1 at the location of row No. 1, so that the straight line No. 1 passes through each ventilation module in row No. 1;

[0140] Draw a straight line No. 2 at the location of row No. 2, so that the straight line No. 2 passes through each ventilation module in row No. 2;

[0141] The position of the target human body is recorded as the target position;

[0142] Get the vertical distance between the target position and the No. 1 straight line, and record it as the No. 1 distance;

[0143] Get the vertical distance between the target position and the second straight line, recorded as the second distance;

[0144] Compare distance 1 and distance 2;

[0145] If the distance No. 1 is ≥ the distance No. 2, select row No. 1 as the air supply side and row No. 2 as the air exhaust side;

[0146] If distance No. 1 is less than distance No. 2, select row No. 2 as the air supply side and row No. 1 as the air exhaust side. When the ventilation module is supplying air, the cold air is blown into the target space at a certain speed, which will cause the cold air to gather at a position far away from the ventilation module supplying air. Therefore, select the ventilation module far away from the target position as the air supply side.

[0148] Obtain the distance between each ventilation module on the exhaust side and the target position, recorded as the exhaust distance;

[0149] Obtain the ventilation module corresponding to the minimum exhaust distance, recorded as the exhaust ventilation module;

[0150] Obtain the distance between each ventilation module on the air supply side and the target position, which is recorded as the air supply distance;

[0151] Obtain the ventilation module corresponding to the maximum air supply distance, which is recorded as the remote ventilation module;

[0152] Obtain the ventilation module corresponding to the minimum air supply distance, which is recorded as the proximal ventilation module;

[0153] Setting a high temperature determination threshold; the high temperature determination threshold is used to determine whether the temperature of the target body is too high, and then determine whether the target body needs to be cooled down quickly;

[0154] If the target body's surface temperature is ≤ the normal body temperature, it means that the target body does not need to be cooled down, and no regulation will be performed;

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

[0156] comparing the temperature difference with a high temperature determination threshold;

[0157] If the temperature difference is less than the high temperature judgment threshold, it means that the temperature of the target human body does not need to be significantly cooled down, then the remote ventilation module is controlled to be in the air supply mode to execute air supply, and the exhaust ventilation module is controlled to be in the exhaust mode to execute exhaust;

[0158] If the temperature difference is ≥ the high temperature judgment threshold, it means that the temperature of the target human body needs to be significantly cooled down, then the near-end ventilation module is controlled to supply air in the air supply mode, and the exhaust ventilation module is controlled to exhaust air in the exhaust mode; the system monitors the human body surface temperature in real time and compares it with the normal body temperature of the human body to determine whether it needs to be adjusted; this control strategy based on the body surface temperature can effectively prevent the human body from being disturbed by cold wind when it is not necessary, and at the same time ensure that timely cooling service is provided when the human body surface temperature is too high; at the same time, this method can select a suitable ventilation module according to the actual body surface temperature of the human body; if the difference between the human body surface temperature and the normal body temperature is greater than or equal to the high temperature judgment threshold, it means that the human body is overheated at this time and needs to be cooled more quickly, then the ventilation module closest to the human body is selected for cooling; if the human body surface temperature is less than the high temperature judgment threshold, it means that although the human body has a high temperature phenomenon at this time, it is not much different from the normal body temperature of the human body and does not need to be cooled quickly, then the ventilation module far from the human body is selected for cooling; this method of dynamically selecting ventilation modules according to the human body surface temperature maximizes the comfort of the human body and reduces the energy consumption of the system.

[0159] The method of monitoring the change of the body surface temperature of the target human body during the process of the ventilation module performing air supply and exhaust, and adjusting the ventilation module performing air supply and exhaust according to the change of the body surface temperature, comprises:

[0160] Set the unit time; the unit time is a fixed time period and can be adaptively adjusted as needed;

[0161] Set a temperature reduction threshold; the temperature reduction threshold is a set standard for reducing the temperature, which refers to the value of the reduced temperature after a unit of time. If the reduced temperature is less than the temperature reduction threshold after a unit of time, it is determined that the temperature reduction standard has not been met; if the reduced temperature is greater than or equal to the temperature reduction threshold, it is determined that the temperature reduction standard has been met;

[0162] The moment when each unit time ends after the air supply starts:

[0163] Obtain the target human body's surface temperature and record it as the current temperature;

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

[0165] Compare current temperature with historical temperatures;

[0166] If the current temperature is ≥ the historical temperature, it means that the cooling effect on the target human body is insufficient, then the ventilation module that is currently in the air supply mode is obtained, and the ventilation module is controlled to be closed, and a ventilation module that belongs to the air supply side and is adjacent to the ventilation module and close to the target human body is obtained, recorded as the No. 1 adjustment ventilation module, and the No. 1 adjustment ventilation module is controlled to perform air supply in the air supply mode; after the ventilation module close to the target human body is adjusted to supply air, the wind speed at the location of the target human body is increased, thereby accelerating the cooling efficiency;

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

[0168] The comparing the temperature drop difference with the temperature drop threshold value includes:

[0169] If the temperature difference = the temperature threshold, it means that the temperature reduction effect is consistent with the expected requirements, and no adjustment is made;

[0170] If the temperature difference is less than the temperature threshold, indicating that the cooling effect is lower than the expected temperature requirement, the ventilation module currently in the air supply mode is obtained, and the ventilation module is controlled to be closed, and a ventilation module that belongs to the air supply side and is adjacent to the ventilation module and close to the target human body is obtained, which is recorded as the No. 2 adjustment ventilation module, and the No. 2 adjustment ventilation module is controlled to perform air supply in the air supply mode; after the ventilation module close to the target human body is adjusted to supply air, the wind speed at the location of the target human body is increased, thereby accelerating the cooling efficiency;

[0171] If the temperature difference is greater than the temperature threshold, it means that the cooling effect is higher than the expected temperature requirement. Then, the ventilation module that is currently in the air supply mode is obtained, and the ventilation module is controlled to be closed. In addition, a ventilation module that belongs to the air supply side and is adjacent to the ventilation module and is far away from the target human body is obtained, which is recorded as the No. 3 adjustment ventilation module. The No. 3 adjustment ventilation module is controlled to perform air supply in the air supply mode. When the ventilation module far away from the target human body is adjusted to supply air, the wind speed at the location of the target human body is reduced, thereby slowing down the cooling efficiency. During the air supply and exhaust process, the changes in the human body surface temperature are monitored, and the ventilation module that performs air supply and exhaust is adjusted according to the temperature change results. When the current temperature monitored is greater than the historical temperature, it means that the current ventilation module has insufficient cooling effect on the human body, and the ventilation module closer to the human body is adjusted to cool the human body. When the current temperature monitored is lower than the historical temperature, the temperature difference is further judged and compared. and the cooling threshold; if the cooling temperature difference is equal to the cooling threshold, it means that the cooling effect is consistent with 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, and the cooling efficiency needs to be improved, then 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, and the cooling efficiency needs to be reduced, then the ventilation module farther 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 used when the cooling effect is not ideal, so as to ensure that the temperature regulation effect is maximized; through this dynamic adjustment, the system can restore the human body surface temperature to normal levels in a relatively short time, avoid excessive cooling or heating, and thereby improve the human body's comfort.
