Description

TECHNICAL FIELD

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

[0002] The existing air conditioners generally uniformly refrigerate the room where they are located, that is, reciprocally sweep the air at a uniform speed or continuously blow the air at an angle adjusted by the user. Such a refrigeration mode is more suitable for a room with fewer people.

[0003] In conference rooms, offices, living rooms and other places, a large number of people often gather. Due to different needs for cold energy among different people, some people often feel hot and some people feel cold. For example, the people who are speaking in the conference room consume more energy, generate more body heat, and accordingly need more cold energy. The people who are quiet in the corner of the conference room consume less energy, generate less body heat, and accordingly need less cold energy. However, the above refrigeration mode of the existing air conditioner cannot meet the refrigeration needs of each person in a place where a large number of people gather. SUMMARY

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

[0005] A further object of the present application is how to accurately identify all the people in the target room by the air conditioner.

[0006] To achieve the above object, the present application provides, in a first aspect, a control method for refrigeration of an air conditioner, comprising:

[0007] obtaining a temperature cloud map of a target room;

[0008] determining the body temperature and the position of each person in the target room from the temperature cloud map;

[0009] determining the ambient temperature of the environment around each person from the temperature cloud map according to the position of each person;

[0017] judging whether each temperature region meets a preset contour area ratio;

[0018] marking all the temperature regions meeting the contour area ratio as personnel regions;

[0019] determining the temperature corresponding to each personnel region as the body temperature and the position corresponding to each personnel region as the personnel position.

[0020] Optionally, the step of determining the ambient temperature of the environment around each personnel from the temperature cloud map according to the personnel position of each personnel comprises:

[0021] obtaining all the temperature regions around each personnel position from the temperature cloud map, the temperature in each temperature region being the same;

[0022] determining, for each personnel position, one of all the temperature regions around the personnel position with the second highest temperature;

[0023] determining the temperature of the one temperature region as the ambient temperature.

[0024] Optionally, the step of controlling the air conditioner to adjust the air supply parameter according to each body-ambient temperature difference and the personnel position corresponding thereto comprises:

[0025] sorting all the body-ambient temperature differences from small to large, and marking multiple body-ambient temperature differences with equal values as one, wherein the ith body-ambient temperature difference is marked as d i .

[0026] determining multiple time lengths t i by the following formula, wherein T is the swing period of the air deflector of the air conditioner, and j is the total number of the body-ambient temperature differences:

[0027]

[0028] sorting all the time lengths t i from large to small, marking multiple time lengths t i with equal values as one, and corresponding the time lengths with the same order to the body-ambient temperature differences;

[0029] According to the relationship between the body temperature difference and the personnel position, the personnel position is corresponded to the time length one by one.

[0030] The control is performed on the time length that the air deflector stays when pointing to each personnel position.

[0031] Optionally, the step of controlling the air conditioner to adjust the air supply parameter according to the body temperature difference and the corresponding personnel position comprises:

[0032] A minimum value is determined from all the body temperature differences.

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

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

[0035] The difference between the body temperature and the corresponding environment temperature is determined.

[0036] It is judged whether the difference is less than or equal to a preset threshold value.

[0037] If it is less than or equal to, the difference is recorded as a body temperature difference.

[0038] Optionally, after the step of determining the difference between the body temperature and the corresponding environment temperature and recording it as a body temperature difference, and before the step of controlling the air conditioner to adjust the air supply parameter according to the body temperature difference and the corresponding personnel position, the control method further comprises:

[0039] In response to detecting a sound, a sound source position of the sound is obtained.

[0040] It is determined whether the sound source position coincides with a personnel position.

[0041] If it coincides, the body temperature difference corresponding to the personnel position is reduced according to a preset condition.

[0042] Optionally, the preset condition is to reduce the body temperature difference by a preset value; and / or,

[0043] Before the body temperature difference corresponding to the personnel position is reduced according to the preset condition, the control method further comprises:

[0045] If the preset decibel value is reached, it is determined whether the duration for which the sound reaches the preset decibel value reaches a preset time length, so as to perform the step of reducing the body-environment temperature difference corresponding to the personnel position according to a preset condition when the preset time length is reached.

[0046] The application provides an air conditioner in a second aspect, including a processor and a memory, the memory has a machine executable program, the processor executes the machine executable program and can realize the control method in any one of the first aspect.

[0047] Based on the foregoing description, those skilled in the art can understand that, in the foregoing technical solutions of the application, the temperature cloud map of the target room is acquired, the body temperature and the personnel position of all the personnel in the target room are determined from the temperature cloud map, the environmental temperature of the environment around each personnel is determined from the temperature cloud map according to the personnel position, the difference between each body temperature and the environmental temperature corresponding to the body temperature is determined and recorded as a body-environment temperature difference, so as to determine the cooling demand degree of each personnel; then, the air conditioner is controlled to adjust the air supply parameter according to each body-environment temperature difference and the personnel position corresponding to the body-environment temperature difference.

[0048] Briefly, the application can control the air conditioner to adjust the air supply parameter by acquiring the temperature difference between each personnel and the environment where the personnel is located. When the temperature difference between a certain personnel and the environment where the personnel is located is large, it indicates that the body temperature of the personnel is much higher than the temperature of the environment where the personnel is located, the environment where the personnel is located can naturally cool the personnel, and the cooling demand degree of the personnel to the air conditioner is low, so the air conditioner can not blow air to the personnel or only blow a small amount of air to the personnel. When the temperature difference between a certain personnel and the environment where the personnel is located is small, it indicates that the body temperature of the personnel is close to the temperature of the environment where the personnel is located, and the cooling effect of the environment where the personnel is located on the personnel is poor, so the cooling demand degree of the personnel to the air conditioner is high, so the air conditioner can blow air to the personnel all the time or frequently blow air to the personnel.

[0049] Further, the application identifies all the temperature regions in which the temperature is in a preset temperature range from the temperature cloud map, and then determines whether each temperature region satisfies a preset contour area ratio, so as to mark all the temperature regions satisfying the contour area ratio as personnel regions, and then determine the temperature corresponding to each personnel region as the body temperature and the position corresponding to each personnel region as the personnel position. Therefore, the application also enables the air conditioner to accurately identify all the personnel in the target room.

[0050] Further, the application acquires all the temperature regions around each personnel position from the temperature cloud map (the temperature in each temperature region is the same), and then determines the temperature next to the temperature of all the temperature regions around each personnel position for each personnel position, so as to determine the temperature of a temperature region as the environmental temperature, so as to ensure that the air conditioner can actively identify the cooling demand degree of each personnel. At the same time, the cold air of the air conditioner is also prevented from blowing to the personnel with a high body temperature due to fever.

[0065] Those skilled in the art should understand that the embodiments described below are only a part of the embodiments of the present application, and are intended to explain the technical principles of the present application, but not to limit the protection scope of the present application. Based on the embodiments provided by the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the protection scope of the present application.

[0066] It should be noted that, in the description of the present application, the terms "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings, which is merely for the convenience of description, and does not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be construed as limiting the present application. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be construed as indicating or implying relative importance.

[0067] Further, it should be noted that, in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be mechanically connected, or electrically connected; can be directly connected, or indirectly connected through an intermediate medium, or can be the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in the present application according to the specific circumstances.

[0068] In addition, it should be noted that, in the description of the present application, the terms "cold" and "heat" are two descriptions of the same physical state. That is, the higher the "cold" of a certain target (such as an evaporator, air, a condenser, etc.), the lower the "heat" it has, and the lower the "cold" it has, the higher the "heat" it has. A certain target absorbs "cold" while releasing "heat", and releases "cold" while absorbing "heat". A certain target stores "cold" or "heat" to keep the target at its current temperature. "Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon, that is, a certain target (such as an evaporator) absorbs heat while refrigerating.

[0070] The structure of the air conditioner in the present application will be described in detail below with reference to Figure 1

[0071] Before that, it needs to be explained that in order to facilitate the description and to enable those skilled in the art to quickly understand the technical solutions of the present application, only the technical features that are more strongly related (directly related or indirectly related) to the technical problems and / or technical concepts to be solved by the present application will be described in the following, and the technical features that are less strongly related to the technical problems and / or technical concepts to be solved by the present application will not be described. Since the technical features that are less strongly related belong to the common knowledge in the art, the disclosure of the present application will not be insufficient even if the less strongly related features are not described.

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

[0073] Among them, the memory 140 can include a memory and a non-volatile memory, and provide execution instructions and data to the processor 130. Exemplarily, the memory can be a high-speed random access memory (RAM), and the non-volatile memory can be at least one disk memory.

[0074] ​The processor 130 is an integrated circuit chip with 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 device, a discrete gate or transistor logic device, a discrete hardware component, a microprocessor, and any other conventional processor.

[0075] As shown in the drawings, Figure 2 In the present application, the air conditioner 100 is used for refrigeration of a target room 200, which can be a conference room, an office, a living room, or any other feasible room. As can be seen from Figure 2 The target room 200 can have multiple personnel 300.

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

[0077] The control method of the air conditioner refrigeration in some embodiments of the present application will be described in detail below with reference to the accompanying Figures 3 to 9

[0078] As shown in the drawings, Figure 3 In some embodiments of the present application, the control method of the air conditioner refrigeration comprises steps S110 to S150, which are as follows:

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

[0080] As shown in the drawings, Figure 4 Step S110 can further comprise:

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

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

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

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

[0085] In the temperature cloud image, each different temperature can be represented by different pixel values or specific numerical values.

[0086] Step S120 determines the body temperature and the position of each person 300 in the target room 200 from the temperature cloud image.

[0087] As shown in the step S120, the step S120 can further include: Figure 5

[0088] Step S121 identifies all temperature regions in the temperature cloud image whose temperatures are within a preset temperature range.

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

[0090] Therefore, if the identified temperature region is within the preset temperature range, it means that the temperature region is most likely to correspond to a human.

[0091] Step S122 determines 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-to-area ratio of each temperature region is calculated. For convenience of description, the contour of each temperature region is denoted as L i (unit: a), the area of each temperature region is denoted as S i (unit: a 2 ), and the contour-to-area ratio of each temperature region is denoted as Mi (unit: a -1 ). Wherein, i is the i-th temperature region, 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 can be any feasible numerical value, such as 2%, 3%, 3.2%, 4%, etc. The specific value of the preset contour area ratio can be determined by the contour area ratio in the image of each angle of the human body.

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

[0096] ​In the embodiment, it is determined whether each temperature region satisfies the preset profile area ratio, specifically, it is determined whether the profile area ratio M of each temperature region satisfies the preset profile area ratio. i is located in the numerical range.

[0097] In step S123, all temperature regions satisfying the profile area ratio are marked as personnel regions.

[0098] In step S124, the temperature corresponding to each personnel region is determined as the body temperature, and the position corresponding to each personnel region is determined as the personnel position.

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

[0100] For example, the temperature cloud map is determined by the infrared image, and the air conditioner 100 establishes the correspondence between the infrared image and the coordinates of the target room 200 when the infrared detection device 110 acquires the infrared image of the target room 200. Therefore, the position relationship of the corresponding personnel 300 in the target room 200 can be determined by the personnel region in the temperature cloud map.

[0101] In short, 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 the appearance of the target room 200 in the eyes of the air conditioner 100, so that the air conditioner 100 can determine the positions of the personnel 300 in the target room 200 through the eyes, just like a person.

[0102] In addition, in other embodiments of the present application, those skilled in the art can set the infrared detection device 110 as a separate device in communication with the air conditioner 100 according to the needs, for example, an infrared camera independent of the air conditioner 100.

[0103] In step S130, the environmental temperature of the surrounding environment of each personnel 300 is determined from the temperature cloud map according to the personnel position.

[0104] In the physical space, the surrounding environment can be the environment around the personnel 300, or a certain region on the body of the personnel 300.

[0105] As shown in the following steps S130 further comprises: Figure 6

[0106] In step S131, all temperature regions around each personnel position are acquired from the temperature cloud map, and the temperature in each temperature region is the same.

[0107] ​In this step, all temperature regions can be identified from the temperature cloud map first, and then the temperature regions that are directly adjacent to the temperature region representing the location of the person can be taken as the final temperature regions for this step.

[0108] Step S132: For each person's location, determine the temperature zone in all surrounding temperature zones that is second only to the person's own.

[0109] Step S133: Determine the temperature of this temperature range as the ambient temperature.

[0110] Those skilled in the art will understand that by using the temperature of the second-highest temperature among all temperature zones surrounding each person 300 as the ambient temperature of that person 300, the influence of objects such as walls behind each person 300 is avoided.

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

[0112] Based on this, those skilled in the art will 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 around each person 300.

[0113] Step S140: Determine the difference between each body temperature and its corresponding ambient temperature, and record it as the body-ambient temperature difference.

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

[0115] Step S141: Determine the difference between each body temperature and its corresponding ambient temperature. This difference is the body temperature minus the ambient temperature.

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

[0117] In this invention, if the difference is large, it indicates that the ambient temperature around the person 300 is low enough to make the person 300 feel cool, without the need for air conditioning 100 to provide cooling. If the difference is small, it indicates that the ambient temperature around the person 300 is high, and the person 300 may feel hot.

[0118] The preset threshold can be any feasible value such as 5℃, 8℃, 10℃, 12℃, or 15℃.

[0119] Step S143, if less than or equal to, the difference is recorded as the body ring temperature difference.

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

[0121] As shown in the embodiment, in one example, step S150 can include: Figure 8

[0122] Step S1511, sorting all body ring temperature differences from small to large, and recording multiple body ring temperature differences with the same value as one, wherein the i-th body ring temperature difference is recorded as d i .

[0123] For example, all body ring temperature differences include 3℃, 5℃, 8℃, 7℃, 5℃, 12℃, 10℃. After sorting from small to large, they are 3℃, 5℃, 5℃, 7℃, 8℃, 10℃, 12℃. After recording multiple body ring temperature differences with the same value as one, they are 3℃ (d1), 5℃ (d2), 7℃ (d3), 8℃ (d4), 10℃ (d5), 12℃ (d6).

[0124] Step S1512, determining multiple time lengths t i by the following formula (1), where T is the swing period of the air deflector 120 of the air conditioner 100, and j is the total number of body ring temperature differences:

[0125]

[0126] In the embodiment, the swing period of the air deflector 120 can be fixed or adjusted according to the instruction issued by the user.

[0127] Step S1513, sorting all time lengths t i from large to small, and recording multiple time lengths t i with the same value as one, and corresponding the time lengths with the same order to the body ring temperature differences.

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

[0129] For convenience of description, all time lengths determined in step S1513 are recorded as t1, t2, t3, t4, t5, t6.

[0130] Step S1514, according to the relationship between the personnel position and the body ring temperature difference, corresponding the personnel position to the time length one by one.

[0131] For example, the personnel position with the body ring temperature difference of 5℃ (d2) is corresponding to the time length t3, and the personnel position with the body ring temperature difference of 8℃ (d4) is corresponding to the time length t4.​

[0132] Step S1515, the control air deflector 120 stays for a corresponding time length when pointing to each personnel position.

[0133] For example, the air deflector 120 stays for a time length t3 when pointing to the personnel position with a body ring temperature difference of 5°C (d2); the air deflector 120 stays for a time length t4 when pointing to the personnel position with a body ring temperature difference of 8°C (d4).

[0134] As shown in another example of the embodiment, step S150 can include: Figure 9

[0135] Step S1521, determining the minimum value from all the body ring temperature differences.

[0136] Step S1522, controlling the air conditioner 100 to blow cold air to the personnel position corresponding to the minimum body ring temperature difference, so as to continuously blow cold air to the personnel 300.

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

[0138] It should be noted that the above-mentioned embodiments of the present application are only a basic embodiment of the present application. In other embodiments of the present application, those skilled in the art can adjust, optimize and configure the schemes and steps in the above-mentioned embodiments according to the needs to achieve further technical effects. In the following, other embodiments of the present application different from the above-mentioned embodiments will be described with reference to the accompanying drawings. Of course, those skilled in the art can also appropriately modify the execution order, running conditions and number of the steps in the embodiments to be described later. The modified embodiments do not deviate from the technical concept and / or technical principle of the present application, and still fall within the protection scope of the present application.

[0139] As shown in another example of the embodiment, step S150 can include: Figure 10 ​As shown, in some embodiments of the present invention, compared with some embodiments described above, the air conditioning cooling control method further includes steps S210 to S230 located between steps S140 and S150, as follows:

[0140] Step S210: In response to the detection of sound, the location of the sound source is obtained.

[0141] Specifically, the air conditioner 100 is equipped with a sound pickup module (with a microphone array), or a device (such as a remote control) that is communicatively connected to the air conditioner 100 is equipped with a sound pickup module. When the sound pickup module detects sound, it calculates the location of the sound source by the difference in the sound signals detected by each microphone in the microphone array.

[0142] Since the technique of determining the location of a sound source using a microphone array is a conventional technique in this field, it will not be explained in detail here.

[0143] Step S220: Determine whether the location of the sound source coincides with the location of a person.

[0144] The location of the sound source is compared with the locations of all people. When a match is found with a person's location, it is determined that the sound source location coincides with that person's location.

[0145] In this embodiment, the location of the sound source is matched with the location of a person. This can mean that the two locations completely overlap, or it can mean that the distance difference between the two locations is less than a certain distance (e.g., 0.2m, 0.5m, 0.7m, 1m, etc.).

[0146] Step S230: If the positions overlap, reduce the body temperature difference corresponding to the personnel's positions according to preset conditions.

[0147] The preset condition is to reduce the body temperature difference by a preset value, which can be any feasible value such as 0.3℃, 0.5℃, 0.8℃, or 1℃.

[0148] Those skilled in the art will understand that, in some embodiments of the present invention, the air conditioner 100 is also capable of actively identifying a person 300 who is speaking and blowing cool air onto that person. Since a person generates more heat when speaking, their body temperature rises, causing them to feel hot. At this time, blowing cool air onto them by the air conditioner 100 can improve the speaker's comfort.

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

[0150] Step S310, determine whether the decibel value of the sound reaches the preset decibel value.

[0151] The preset decibel value can be 55 decibels, 60 decibels, 65 decibels, 70 decibels, etc.

[0152] Step S320, if it is reached, determine whether the duration of the sound reaching the preset decibel value reaches the preset time length, so as to execute step S230 again when it is reached.

[0153] Those skilled in the art can understand that, in the embodiments, by determining the decibel value of the sound source and the duration of existence, it is ensured that the person speaking is always speaking and the person with rising body temperature, rather than the person occasionally speaking and not rising body temperature, so as to improve the intelligence of the air conditioner 100.

[0154] So far, the technical solutions of the present application have been described in combination with the foregoing embodiments, but those skilled in the art can easily understand that the protection scope of the present application is not limited to these specific embodiments. Those skilled in the art can split and combine the technical solutions in the above-mentioned embodiments, or make equivalent changes or replacements to the related technical features, without deviating from the technical principles of the present application. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principles of the present application shall fall within the protection scope of the present application.
