Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioners, and specifically provides an air conditioner and a refrigeration control method thereof. Background Art

[0002] Existing air conditioners generally cool the room evenly, that is, they sweep air back and forth at a uniform speed, or blow air continuously at an angle adjusted by the user. This cooling method is more suitable for rooms with fewer people.

[0003] In places such as conference rooms, offices, and living rooms, many people often gather. Due to the different cooling requirements of different people, some people often feel hotter and some feel colder. For example, people who are talking in the conference room consume more energy and generate more heat from their bodies, so they need more cooling. People who are quiet in the corners of the conference room consume less energy and generate less heat from their bodies, so they need less cooling. However, the above cooling method of existing air conditioners cannot meet the cooling needs of people in places where many people gather. Summary of the invention

[0004] One object of the present invention is to solve the problem that the existing air conditioner cannot actively meet the different cooling needs of multiple people.

[0005] A further object of the present invention is to enable the air conditioner to accurately identify all persons in the target room.

[0008] Determine the body temperature and location of all persons in the target room from the temperature cloud map;

[0010] Determine the difference between each body temperature and the corresponding ambient temperature, and record it as body-environment temperature difference;

[0011] The air conditioner is controlled to adjust air supply parameters according to each body temperature difference and the corresponding position of the person.

[0012] Optionally, the step of obtaining a temperature cloud map of the target room includes:

[0013] Acquiring an infrared signal in the target room by an infrared detection device arranged on the air conditioner;

[0014] The temperature cloud map is constructed according to all the acquired infrared signals.

[0019] The temperature corresponding to each of the personnel areas is determined as the body temperature, and the position corresponding to each of the personnel areas is determined as the personnel position.

[0020] Optionally, the step of determining the ambient temperature of the surrounding environment of each person from the temperature cloud map according to the position of each person includes:

[0021] Acquire all temperature areas around each of the personnel positions from the temperature cloud map, wherein the temperature in each of the temperature areas is the same;

[0022] For each of the personnel positions, determine the one whose temperature is next to the personnel position among all the temperature zones around the personnel position;

[0023] The temperature of the one of the temperature regions is determined as the ambient temperature.

[0024] Optionally, the step of controlling the air conditioner to adjust air supply parameters according to each of the body temperature differences and the corresponding personnel positions includes:

[0025] All the body ring temperature differences are sorted from small to large, and multiple body ring temperature differences with equal values ​​are recorded as one, where the i-th body ring temperature difference is recorded as d i ;

[0026] The multiple durations t are determined by the following formula i , where T is the swing period of the air guide plate of the air conditioner, and j is the total number of the body temperature difference:

[0027]

[0028] For all the durations t i Sort them from large to small, and put multiple durations t with equal values i Denote as one, and the time lengths with the same order are matched one to one with the body annular temperature differences;

[0029] According to the relationship between the personnel position and the body temperature difference, the personnel position and the duration are made to correspond one to one;

[0030] The wind deflector is controlled to stay for a corresponding length of time when pointing to each of the personnel positions.

[0031] Optionally, the step of controlling the air conditioner to adjust air supply parameters according to each of the body temperature differences and the corresponding personnel positions includes:

[0032] Determine the one with the smallest value from all the body annular temperature differences;

[0033] The air conditioner is controlled to blow toward the personnel position corresponding to the smallest body temperature difference.

[0034] Optionally, the step of determining the difference between each body temperature and the corresponding ambient temperature and recording it as the body temperature difference comprises:

[0035] Determining the difference between each of the body temperatures and the corresponding ambient temperature;

[0036] Determining whether the difference is less than or equal to a preset threshold;

[0046] In a second aspect, the present invention provides an air conditioner, comprising a processor and a memory, wherein a machine executable program is stored in the memory, and when the processor executes the machine executable program, the control method described in any one of the first aspects can be implemented.

[0047] Based on the foregoing description, those skilled in the art will be able to understand that, in the aforementioned technical scheme of the present invention, by obtaining a temperature cloud map of the target room, the body temperatures and positions of all personnel in the target room are determined from the temperature cloud map, the ambient temperature of the environment surrounding each person is determined from the temperature cloud map according to the position of each person, the difference between each body temperature and its corresponding ambient temperature is determined and recorded as the body temperature difference to determine the degree of cooling required for each person; then, according to each body temperature difference and its corresponding personnel position, the air supply parameters of the air conditioner are controlled.

[0048] In simple terms, the present invention can control the air conditioning to adjust the air supply parameters by obtaining the temperature difference between each person and the environment in which they are located. When the temperature difference between a person and the environment in which they are located is large, it means that their body temperature is much higher than the temperature of the environment in which they are located, and the environment in which they are located can naturally cool down the person, and the person's need for cooling by the air conditioner is low. At this time, the air conditioner can be stopped from blowing air to them, or only blow a small amount of air. When the temperature difference between a person and the environment in which they are located is small, it means that their body temperature is close to the temperature of the environment in which they are located, and the cooling effect of the environment in which they are located on the person is poor. The person's need for cooling by the air conditioner is high, and the air conditioner can be blown to them all the time, or blow air frequently.

[0049] Furthermore, the present invention identifies all temperature areas whose temperatures are within a preset temperature range from the temperature cloud map, and then determines whether each temperature area meets a preset contour area ratio, so as to mark all temperature areas that meet the contour area ratio as personnel areas, and then determines the temperature corresponding to each personnel area as body temperature, and determines the position corresponding to each personnel area as the personnel position. Therefore, the present invention also enables the air conditioner to accurately identify all personnel in the target room.

[0050] Furthermore, the present invention obtains all temperature areas around each person's position from the temperature cloud map (the temperature in each temperature area is the same), and then for each person's position, determines the temperature of all temperature areas around it that is next to it, so as to determine the temperature of one temperature area as the ambient temperature, thereby ensuring that the air conditioner can actively identify the degree of cooling required by each person. At the same time, it also prevents the cold air of the air conditioner from blowing towards people with high body temperature due to fever.

[0051] Other beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand the improved purposes, features and advantages of the present invention.

[0065] It should be understood by those skilled in the art that the embodiments described below are only some embodiments of the present invention, rather than all embodiments of the present invention, and these embodiments are intended to explain the technical principles of the present invention, rather than to limit the protection scope of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should still fall within the protection scope of the present invention.

[0066] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0067] Furthermore, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0068] In addition, it should be noted that in the description of the present invention, the terms "cold" and "heat" are two descriptions of the same physical state. That is, the higher the "cold" of a certain target object (such as an evaporator, air, condenser, etc.), the lower the "heat" it has, and the lower the "cold" it has, the higher the "heat" it has. A certain target object will release "heat" while absorbing "cold", and will absorb "heat" while releasing "cold".

Those skilled in the art should understand that, under the premise of being able to implement the technical solution described in the present invention, no matter how the composition, implementation and positional relationship of each functional module change, they will not deviate from the technical principle of the present invention, and therefore should fall within the protection scope of the present invention.

[0070] Refer to the following Figure 1 The structure of the air conditioner in the present invention is described in detail.

[0071] It should be noted that, for the convenience of description and to enable those skilled in the art to quickly understand the technical solution of the present invention, the following text only describes the technical features that are strongly related (directly or indirectly related) to the technical problem and / or technical concept to be solved by the present invention, and will not describe the technical features that are weakly related to the technical problem and / or technical concept to be solved by the invention. Since the technical features with a weaker degree of correlation belong to the common knowledge in the field, even if the present invention does not describe the features with a weaker degree of correlation, it will not lead to insufficient disclosure of the present invention.

[0072] like Figure 1 As shown, in the present invention, the air conditioner 100 includes an infrared detection device 110, an air guide plate 120, a processor 130 and a memory 140. The infrared detection device 110 is used to obtain an infrared signal of the room where the air conditioner 100 is located, and the air guide plate 120 is used to guide the wind blown out by the air conditioner 100. The memory 140 stores a machine executable program 141, and when the processor 130 executes the machine executable program, it can implement the control method described in any of the embodiments below.

[0073] The memory 140 may include a memory and a non-volatile memory, and provide execution instructions and data to the processor 130. For example, the memory may be a high-speed random access memory (RAM), and the non-volatile memory may be at least one disk storage.

[0074] The processor 130 is an integrated circuit chip that has the ability to process signals. The processor 130 can be a general-purpose processor, such as a central processing unit (CPU), a network processor (NP), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, microprocessors, and any other conventional processors.

[0075] like Figure 2 As shown, in the present invention, the air conditioner 100 is used to cool the target room 200, and the target room 200 can be any feasible room such as a conference room, an office, a living room, etc. Figure 2 As can be seen from the figure, there may be multiple persons 300 in the target room 200.

[0076] It should be noted that, for the convenience of description, the air conditioner 100 described below generally refers to the indoor unit of the air conditioner 100 unless otherwise specified.

[0077] Please refer to the attached Figures 3 to 9 The air conditioning refrigeration control method in some embodiments of the present invention is described in detail.

[0078] like Figure 3 As shown, in some embodiments of the present invention, the air conditioning refrigeration control method includes steps S110 to S150, which are as follows:

[0079] Step S110, obtaining a temperature cloud map of the target room 200.

[0080] like Figure 4 As shown, step S110 may further include:

[0081] Step S111 , acquiring infrared signals in the target room 200 by using the infrared detection device 110 provided on the air conditioner 100 .

[0082] The infrared detection device 110 may be a thermopile or a thermal imaging sensor.

[0083] Step S112, constructing a temperature cloud map according to all acquired infrared signals.

[0084] For example, the infrared detection device 110 is a thermal imaging sensor, and an infrared image of the target room 200 is acquired by the thermal imaging sensor, and the infrared image can be determined as a temperature cloud map.

[0085] In the temperature cloud map, different temperatures can be represented by different pixel values ​​or by specific numerical values.

[0086] Step S120, determining the body temperature and positions of all persons 300 in the target room 200 from the temperature cloud map.

[0087] like Figure 5 As shown, step S120 may further include:

[0088] Step S121, identifying all temperature regions whose temperatures are within a preset temperature range from the temperature cloud map.

[0089] The preset temperature range represents the normal body temperature of a human body, which may be 36° C. to 37° C., or any other feasible temperature range.

[0090] To this end, if the identified temperature region is within the preset temperature range, it means that the temperature region corresponds most likely to a human being.

[0091] Step S122, determining whether each temperature region satisfies a preset contour area ratio.

[0092] Specifically, the contour and area of ​​each temperature region are obtained, and then the contour and area ratio of each temperature region is calculated. For the convenience of explanation, the contour of each temperature region is now recorded as L i (unit is a), and the area of ​​each temperature region is denoted as S i (Unit is a 2 ), the contour area ratio of each temperature region is recorded as Mi (unit is a -1 ). Wherein, i is the i-th temperature zone, and a can be any feasible unit such as mm, cm, etc.

[0093] Then, M i =L i ÷S i .

[0094] The preset contour area ratio may be any feasible value, such as 2%, 3%, 3.2%, 4%, etc. The specific value of the preset contour area ratio may be determined by the contour area ratio in images of the human body at various angles.

[0095] In this embodiment, the preset contour area ratio is preferably a numerical range, for example, 2% to 4%, 1.5% to 3.5%, 2.2% to 3.8%, etc.

[0096] In this embodiment, it is determined whether each temperature region satisfies a preset contour area ratio. Specifically, it is determined whether the contour area ratio M of each temperature region satisfies a preset contour area ratio M of each temperature region. i Is it within this value range?

[0097] Step S123: Mark all temperature areas that meet the contour area ratio as personnel areas.

[0098] Step S124: determine the temperature corresponding to each personnel area as the body temperature, and determine the position corresponding to each personnel area as the personnel position.

[0099] Specifically, in the temperature cloud map, the temperature corresponding to each personnel area is identified and determined as the body temperature. The position of each personnel area in the temperature cloud map is used to determine the position of the personnel.

[0100] For example, the temperature cloud map is determined by the infrared image, and when the air conditioner 100 obtains the infrared image of the target room 200 through the infrared detection device 110, a coordinate correspondence relationship between the infrared image and the target room 200 is established. Therefore, the position relationship of the corresponding person 300 in the target room 200 can be determined through the personnel area in the temperature cloud map.

[0101] In simple terms, the infrared detection device 110 can be understood as the eyes of the air conditioner 100, and the temperature cloud map can be understood as what the target room 200 looks like in the eyes of the air conditioner 100, so that the air conditioner 100 can determine the location of each person 300 in the target room 200 through the eyes, just like a person.

[0102] In addition, in other embodiments of the present invention, those skilled in the art may also configure the infrared detection device 110 as an independent device that is communicatively connected to the air conditioner 100 , such as an infrared camera independent of the air conditioner 100 , as needed.

[0103] Step S130 , determining the ambient temperature of the surroundings of each person 300 from the temperature cloud map according to the position of each person.

[0104] In the physical space, the surrounding environment may be the surrounding environment of each person 300 , or may be a certain area on the body of each person 300 .

[0105] like Figure 6 As shown, step S130 further includes:

[0106] Step S131, obtaining all temperature areas around each person's position from the temperature cloud map, and the temperature in each temperature area is the same.

[0107] In this step, all temperature regions may be identified from the temperature cloud map first, and then the temperature regions directly adjacent to the temperature region representing the position of the person in all temperature regions may be used as the final temperature regions of this step.

[0108] Step S132: for each personnel position, determine the temperature of all surrounding temperature zones next to the personnel position.

[0109] Step S133: determining the temperature of the temperature zone as the ambient temperature.

[0110] Those skilled in the art will appreciate that by using the temperature of all temperature zones around each person 300 that is next to the person 300 as the ambient temperature of the corresponding person 300 , the influence of objects such as walls behind each person 300 is avoided.

[0111] In an example scenario of the present invention, the temperature region obtained in step S131 includes a region representing a chair (e.g., an armrest), a region representing a table, a region representing a hot water cup, etc. The temperature region determined in step S132 is a region representing a chair. Step S133 determines the temperature of the chair as the ambient temperature of the person 300.

[0112] Based on this, those skilled in the art can understand that steps S131 to S133 can make the determined ambient temperature around each person 300 closer to the temperature of the air around each person 300 , so that the air conditioner 100 can determine the ambient temperature of each person 300 .

[0113] Step S140, determining the difference between each body temperature and its corresponding ambient temperature, and recording it as the body temperature difference.

[0114] like Figure 7 As shown, step S140 further includes:

[0115] Step S141, determining the difference between each body temperature and its corresponding ambient temperature, wherein the difference is the body temperature minus the ambient temperature.

[0116] Step S142, determining whether the difference is less than or equal to a preset threshold.

[0117] In the present invention, if the difference is large, it means that the ambient temperature around the person 300 is low enough to make the person 300 feel cool, and there is no need for cooling by the air conditioner 100. If the difference is small, it means that the ambient temperature around the person 300 is high, and the person 300 may feel hot.

[0118] The preset threshold value may be any feasible value such as 5°C, 8°C, 10°C, 12°C, 15°C, etc.

[0119] Step S143: If it is less than or equal to, the difference is recorded as the body annular temperature difference.

[0120] Step S150, controlling the air conditioner 100 to adjust air supply parameters according to the temperature difference of each body environment and the corresponding personnel position.

[0121] like Figure 8 As shown, in an example of this embodiment, step S150 may include:

[0122] Step S1511, sort all the body annular temperature differences from small to large, and record multiple body annular temperature differences with equal values ​​as one, where the i-th body annular temperature difference is recorded as d i .

[0123] For example, all the body temperature differences include 3°C, 5°C, 8°C, 7°C, 5°C, 12°C, and 10°C. They are sorted from small to large as 3°C, 5°C, 5°C, 7°C, 8°C, 10°C, and 12°C. Multiple body temperature differences with the same value are recorded as one, which is 3°C (d1), 5°C (d2), 7°C (d3), 8°C (d4), 10°C (d5), and 12°C (d6).

[0124] Step S1512: determine multiple durations t by the following formula (1): i , where T is the swing period of the air guide plate 120 of the air conditioner 100, and j is the total number of body-circumferential temperature differences:

[0125]

[0126] In an embodiment, the swing period of the air guide plate 120 may be fixed, or may be adjusted accordingly according to instructions issued by a user.

[0127] Step S1513, for all durations t i Sort from largest to smallest, and separate multiple durations t with equal values i Denote it as one, and make a one-to-one correspondence between the duration of the same sequence and the body temperature difference.

[0128] For details, please refer to the example of the body annular temperature difference in step S1511.

[0129] For the sake of convenience, all the durations determined in step S1513 are recorded as t1, t2, t3, t4, t5, and t6.

[0130] Step S1514, according to the relationship between the personnel position and the body temperature difference, the personnel position and the duration are made to correspond one to one.

[0131] For example, the position of a person whose temperature difference with the body environment is 5° C. (d2) is made to correspond to the time length t3; and the position of a person whose temperature difference with the body environment is 8° C. (d4) is made to correspond to the time length t4.

[0132] Step S1515, controlling the air guide plate 120 to stay for a corresponding period of time when pointing to each personnel position.

[0133] For example, when the air guide plate 120 points to a position of a person whose body temperature difference is 5°C (d2), the stay time is t3; when the air guide plate 120 points to a position of a person whose body temperature difference is 8°C (d4), the stay time is t4.

[0134] like Fig. 9 As shown, in another example of this embodiment, step S150 may include:

[0135] Step S1521, determining the one with the smallest value from all body annular temperature differences.

[0136] Step S1522, controlling the air conditioner 100 to blow toward the position of the person corresponding to the smallest body temperature difference, so as to continuously blow cold air to the person 300.

[0137] Based on the foregoing description, it can be understood by those skilled in the art that, in some embodiments of the present invention, the air conditioner 100 can be controlled to adjust the air supply parameters by obtaining the temperature difference between each person 300 and the environment in which they are located. When the temperature difference between a certain person 300 and the environment in which they are located is large (indicating that their body temperature is much higher than the temperature of the environment in which they are located, the environment in which they are located can naturally cool down the person 300, and the person 300 has a low degree of cooling demand for the air conditioner 100), the air conditioner 100 does not blow air to them, or only blows a small amount of air. When the temperature difference between a certain person 300 and the environment in which they are located is small (indicating that their body temperature is close to the temperature of the environment in which they are located, the environment in which they are located has a poor cooling effect on the person 300, and the person 300 has a high degree of cooling demand for the air conditioner 100), the air conditioner 100 blows air to them all the time, or blows air frequently.

[0138] It should be noted that the above-mentioned embodiment of the present invention is only a basic embodiment of the present invention. In other embodiments of the present invention, those skilled in the art may also adjust, optimize and configure the schemes and steps in the above-mentioned embodiments as needed to achieve further technical effects. Other embodiments of the present invention different from the above-mentioned embodiments will be described in conjunction with the accompanying drawings hereinafter. Of course, those skilled in the art may also make appropriate modifications to the execution order, operating conditions and quantity of the steps in the embodiments to be described hereinafter according to actual needs. The modified embodiments do not deviate from the technical concept and / or technical principle of the present invention and should still fall within the scope of protection of the present invention.

[0139] like Fig.10As shown, in some further embodiments of the present invention, compared with some embodiments described above, the air conditioning refrigeration control method further includes steps S210 to S230 located between step S140 and step S150, which are specifically as follows:

[0140] Step S210, in response to detecting a sound, obtaining the sound source position of the sound.

[0141] Specifically, the air conditioner 100 is provided with a sound pickup module (having a microphone array), or a device (such as a remote controller) that is communicatively connected to the air conditioner 100 is provided with a sound pickup module. When the sound pickup module detects a sound, the sound source position of the sound is calculated by the difference of the sound signals detected by each microphone in the microphone array.

[0142] Since the technical means of determining the sound source position by using a microphone array is a conventional technical means in the art, it will not be further explained here.

[0143] Step S220, determining whether the sound source position coincides with a certain person's position.

[0144] The sound source position is compared with the positions of all personnel. When a certain personnel position is matched, it is determined that the sound source position coincides with the personnel position.

[0145] In this embodiment, the sound source position matches a certain person position, which may indicate that the two positions completely overlap, or may indicate that the distance difference between the two positions is less than a certain distance (eg, 0.2 m, 0.5 m, 0.7 m, 1 m, etc.).

[0146] Step S230: If they overlap, the body temperature difference corresponding to the personnel position is reduced according to preset conditions.

[0147] The preset condition is to reduce the body-annular temperature difference by a preset value, which is any feasible value such as 0.3°C, 0.5°C, 0.8°C, 1°C, etc.

[0148] Those skilled in the art can understand that in some other embodiments of the present invention, the air conditioner 100 can actively identify the person 300 who is speaking and blow cold air to the person 300 who is speaking. Since a person generates more heat when speaking, the body temperature rises, and thus the person feels hot. At this time, the air conditioner 100 blows cold air to the person, which can improve the comfort of the person who is speaking.

[0149] like Fig.11 As shown, in some other embodiments of the present invention, compared with some other embodiments described above, the air conditioning refrigeration control method further includes step S310 and step S320 located before step S230, which are specifically as follows:

[0150] Step S310, determining whether the decibel value of the sound has reached a preset decibel value.

[0151] The preset decibel value may be any feasible value such as 55 decibels, 60 decibels, 65 decibels, 70 decibels, etc.

[0152] Step S320, if reached, determine whether the duration of the sound reaching the preset decibel value has reached a preset time length, and then execute step S230 when reached.

[0153] Those skilled in the art can understand that, in the embodiment, by determining the decibel value of the sound source and the duration of its existence, it is ensured that the person speaking is a person who speaks all the time and whose body temperature rises, rather than a person who speaks occasionally and whose body temperature does not rise, thereby improving the intelligence of the air conditioner 100.

[0154] So far, the technical solution of the present invention has been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the present invention is not limited to these specific embodiments. Without departing from the technical principles of the present invention, those skilled in the art can split and combine the technical solutions in the above embodiments, and can also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principles of the present invention will fall within the protection scope of the present invention.
