[0032] In order to enable a more detailed understanding of the features and technical content of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure is described in detail below, and the accompanying drawings are used for reference only and do not limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, through a plurality of details, a sufficient understanding of the disclosed embodiments is provided. However, one or more embodiments can still be implemented without these details. In other cases, well-known structures and devices can be simplified to facilitate the drawings.

[0033] The terms "first", "second", and the like in the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the embodiments of the present disclosure described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0034] Unless otherwise specified, the term "a plurality of" means two or more.

[0035] In the embodiments of the present disclosure, the character " / " represents a "or" relationship between the objects before and after. For example, A / B represents: A or B.

[0036] The term "and / or" is a description of the relationship between the objects, which means that there can be three relationships. For example, A and / or B, which means: A or B, or, A and B, three kinds of relationship.

[0037] In the embodiment of the present disclosure, a near field communication (NFC) tag is configured on the clothes of a user in the action area of an air conditioner, and the clothes information is included in the NFC tag, wherein the clothes information includes: ① clothes category information, such as a thin long-sleeved shirt, a thick long-sleeved shirt, a light and thin lady's top, a sleeveless short pajama, etc.; ② belonging crowd information: men, women, etc.; ③ clothes material information: cotton, hemp, silk, wool, leather, chemical fiber, blended fabric, mercerized cotton, chiffon, mulberry silk, etc.; ④ clothes size information; ⑤ washing parameter information, etc. In this way, after the terminal scans the NFC tag on the clothes, the terminal can communicate with the air conditioner or a cloud server, and the NFC tag information read after the last scanning is obtained. In this way, the air conditioner or the cloud server can determine the current PMV value according to the current clothes category information and the current clothes belonging crowd information in the NFC tag information, and then perform corresponding air conditioner PMV control. It can be seen that in the embodiment, the factors affecting the air conditioner PMV control can be directly obtained through the NFC tag, so that the air conditioner PMV control process is more easily realized, and the universality of the air conditioner PMV application is improved. Moreover, the information carried by the clothes NFC tag is directly collected, and the information collected by other household electrical appliances and language devices is more accurate and has lower cost, thereby further improving the accuracy of the air conditioner PMV control and reducing the cost of the air conditioner control.

[0038] Figure 1 is a structural schematic diagram of an air conditioner system provided by the embodiment of the present disclosure. As shown in Figure 1 , the system includes an air conditioner 100 and a terminal 200. The terminal 200 has a function of scanning an NFC tag, that is, the terminal can obtain the clothes information included in the corresponding NFC tag after contacting the NFC tag on the clothes worn by a human body.

[0039] The air conditioner 100 and the terminal 200 can communicate. In some embodiments, the air conditioner 100 and the terminal 200 can perform short-distance wireless communication, which can include Bluetooth communication, infrared communication, Zigbee communication, or wireless local area network (WIFI) communication, etc. In this way, the air conditioner 100 can obtain the clothes information reported by the terminal 200, and the clothes information is obtained by the terminal 200 after reading the near field communication (NFC) tag on the clothes worn by a user. In this way, the air conditioner 100 can determine the corresponding comfort PMV value according to the clothes information, and operates according to the comfort PMV value.

[0040] In some embodiments, in order to save the memory resources of the air conditioner 100 and improve the operation efficiency of the air conditioner 100, the air conditioner 100 is Figure 1As shown, the air conditioning system can also include a cloud server 300, which can communicate with the air conditioner 100 and the terminal 200 respectively. Moreover, after the terminal 200 reads the near field communication (NFC) tag on the clothes of the user and obtains the clothes information, the terminal 200 can upload the clothes information to the cloud server 300. In this way, the cloud server 300 can determine the corresponding PMV value according to the clothes information, and control the air conditioner 100 to operate according to the PMV value.

[0041] As can be seen, in the embodiment of the present disclosure, the air conditioner or the cloud server can determine the corresponding PMV value according to the clothes information of the current user in the action area of the air conditioner reported by the terminal, and control the air conditioner to operate according to the PMV value, wherein the clothes information is obtained by the terminal after reading the near field communication (NFC) tag on the clothes of the user.

[0042] Figure 2 is a flowchart of a method for controlling an air conditioner provided by the embodiment of the present disclosure. As shown in Figure 2 The control process of the air conditioner includes:

[0043] Step 201: In the case of receiving the human comfort intelligent control mode (PMV) instruction sent by the air conditioner, obtain the first current parameter information of the current user in the action area of the air conditioner reported by the terminal, wherein the first current parameter information is obtained by the terminal after reading the near field communication (NFC) tag on the clothes of the current user, and includes the current clothes category information and the current clothes belonging to the crowd information.

[0044] At present, the air conditioner can adjust the temperature in the action area, so it can perform cooling or heating operation according to the received user instruction. Alternatively, the air conditioner can collect the indoor temperature value and the outdoor temperature value in the area in real time or at regular intervals, and perform cooling or heating operation according to the collected indoor temperature value and outdoor temperature value. For example, when the current indoor temperature value Ta collected is greater than or equal to 23℃, or the current outdoor temperature value Tao is greater than or equal to 20℃, the air conditioner can perform cooling operation. However, if the current indoor temperature value Ta collected is less than 23℃, and the current outdoor temperature value Tao is less than 20℃, the air conditioner can perform heating operation.

[0045] No matter whether the air conditioner performs cooling operation or heating operation, there can be a PMV mode. PMV is a human comfort intelligent control system, which can determine a best comfort degree and humidity according to the temperature adaptation of Chinese people themselves, that is, after the PMV mode is started, the air conditioner can set the best target temperature according to the indoor and outdoor temperature difference.

[0046] In the embodiments of the present disclosure, the air conditioner can start the PMV mode according to the collected indoor temperature value or the collected indoor temperature value and indoor humidity value. In some embodiments, the air conditioner sending the human comfort intelligent control mode PMV instruction comprises: the air conditioner in the current operating mode acquires the current indoor temperature value in the action area; and in the case that the current indoor temperature value meets the set condition matched with the current operating mode, the air conditioner sends the human comfort intelligent control mode PMV instruction.

[0047] In the process of air conditioner cooling operation, if the collected current indoor humidity value is less than the set humidity, and the current indoor temperature value Ta is less than or equal to the target temperature, the air conditioner can be controlled to adopt the anti-direct blowing mode and start the PMV mode at the same time, that is, the air conditioner can send the human comfort intelligent control mode PMV instruction. For example, the set humidity can be 70%, and the target temperature is 26℃. In this way, if the current indoor humidity value is less than 70%, the air conditioner can be controlled to enter the maximum air volume cooling mode and run, and if the current indoor temperature value Ta is less than or equal to 26℃, the air conditioner can be controlled to adopt the anti-direct blowing mode and start the PMV mode at the same time. Of course, if the air conditioner cannot collect the indoor humidity value, if the current indoor temperature value is less than or equal to 26℃, the air conditioner can be controlled to adopt the anti-direct blowing mode and start the PMV mode at the same time.

[0048] In the process of air conditioner heating operation, if the collected current indoor temperature value is greater than or equal to the target temperature, the PMV mode can be started, that is, the air conditioner can send the human comfort intelligent control mode PMV instruction. For example, the target temperature is 22℃. In this way, if the current indoor temperature value Ta is greater than or equal to 22℃, the PMV mode can be started.

[0049] When the air conditioner starts the PMV mode, that is, the air conditioner can send the human comfort intelligent control mode PMV instruction, the air conditioner or the cloud server receiving the sent human comfort intelligent control mode PMV instruction can determine that the air conditioner has started the PMV mode and needs to automatically set the optimal target temperature.

[0050] In the embodiments of the present disclosure, the comfort PMV value can be determined according to the environmental factors and non-environmental factors, and the optimal target temperature corresponding to the air conditioner can be determined according to the comfort PMV value. In the non-environmental factors, the human clothing thermal resistance and the metabolic rate and the like can be determined according to the information included in the near field communication NFC tag on the current user's clothing in the action area of the air conditioner. Therefore, after the terminal contacts the near field communication NFC tag on the current user's clothing in the action area of the air conditioner, the corresponding first parameter information can be scanned and uploaded to the air conditioner or the cloud server. In this way, in the case that the air conditioner sends the human comfort intelligent control mode PMV instruction, the air conditioner or the cloud server can acquire the first parameter information reported by the terminal, and the first current parameter information corresponding to the current time.

[0051] The terminal scans the NFC tag to obtain corresponding clothes information, and therefore, the first parameter information can include clothes category information and clothes belonging group information, and the first current parameter information includes current clothes category information and current clothes belonging group information. The clothes category information includes underpants, shorts, shirts, sweaters, trousers, and the like, and the current clothes belonging group information includes men, women, and neutral.

[0052] In step 202, a current clothing thermal resistance value that matches the current clothes category information is determined, and a current PMV value of comfort degree is obtained according to the current clothing thermal resistance value and the current clothes belonging group information.

[0053] In the embodiments of the present disclosure, the air conditioner can store a corresponding relationship between clothes category information and clothing thermal resistance values, and a corresponding relationship between group information and PMV value calculation formulas. Alternatively, the cloud server can store a corresponding relationship between clothes category information and clothing thermal resistance values, and a corresponding relationship between group information and PMV value calculation formulas.

[0054] Table 1 is a corresponding relationship between clothes category information and clothing thermal resistance values provided by the embodiments of the present disclosure.

[0055] Clothing item information Clothing thermal resistance l cl (m2.k / w) Underwear, shorts, thin socks, sandals 0.05 Skirt, knee-length stockings, light jacket 0.07 Underwear, shirt, long pants 0.095 … …

[0056] Table 1

[0057] In this way, if the air conditioner or the cloud server stores the corresponding relationship shown in Table 1, if the current clothes category information in the first current parameter information is underpants, shirts, and trousers, the current clothing thermal resistance value l c may be determined to be 0.095. Of course, the present disclosure is not limited to this, and a corresponding relationship between clothes category information, clothes belonging group information, and clothing thermal resistance values can also be stored.

[0058] Table 2 is a corresponding relationship between clothes category information, clothes belonging group information, and clothing thermal resistance values provided by the embodiments of the present disclosure. In this way, if the air conditioner or the cloud server stores the corresponding relationship shown in Table 2, if the current clothes category information in the first current parameter information is underpants, shirts, trousers, and shoes, and the current clothes belonging group information is neutral, the current clothing thermal resistance value l c may be determined to be 0.145.

[0059] The air conditioner or the cloud server also stores a corresponding relationship between group information and PMV value calculation formulas. In some embodiments, the PMV value calculation formula corresponding to the male group information is formula (1), and the PMV value calculation formula corresponding to the female group information is formula (2).

[0064] wherein M is the metabolic rate of the human body, W is the external mechanical work, P a is the water vapor pressure, t a is the indoor temperature value, f el is the clothing surface area coefficient, t el is the clothing surface temperature value, t r is the average radiant temperature value, h c is the convective heat transfer coefficient.

[0065] According to formula (1) and formula (2), the main parameters affecting the PMV value of the air conditioner can be determined, including M, W, P a , t a , f el , t el , t r , h c . The metabolic rate M of the human body can also be set, for example, 70 W / M 2 . Alternatively, the air conditioner or the cloud server stores a corresponding relationship between the activity state and the metabolic rate M of the human body, so that the air conditioner can determine the corresponding current metabolic rate M of the human body according to the saved corresponding relationship after obtaining the current activity state of the current user through the image acquisition device. Alternatively, the air conditioner sends the current activity state of the current user to the cloud server after obtaining the current activity state of the current user through the image acquisition device, and the cloud server can determine the corresponding current metabolic rate M of the human body according to the saved corresponding relationship.

[0066] Table 3 is a corresponding relationship between the activity state and the metabolic rate M of the human body provided by the embodiment of the present disclosure.

[0068] Table 3

[0069] If the current activity state of the current user is obtained by the air conditioner through the image acquisition device and sent to the cloud server, the cloud server can determine that the current metabolic rate M of the human body is 115 W / m 2 .

[0070] The external mechanical work W can be a set default value, for example, W = 0 W / m 2 . P a , t a , f el , t el , t r , h c is not only related to the current clothing thermal resistance value and the current clothing population information, but also related to other parameters obtained by the air conditioner, so in some embodiments, the current comfort PMV value is obtained according to the current clothing thermal resistance value and the current clothing population information, including: obtaining the second current parameter value reported by the air conditioner, wherein the second current parameter value includes: the current indoor temperature value, the air speed value determined according to the current indoor temperature value, the current indoor humidity value, and the current mean radiant temperature value; determining the third current parameter value according to the current clothing thermal resistance value and the second current parameter value, wherein the third current parameter value includes: the current clothing surface area coefficient f el , the current clothing surface temperature value t el , and the current convective heat exchange coefficient h c, and current water vapor partial pressure P a ; determining a current PMV value calculation formula matched with the current clothing group information; determining the current comfort PMV value according to the second current parameter value, the third current parameter value, and the current PMV value calculation formula.

[0071] The air conditioner can obtain a current indoor temperature value t a by temperature collection, and can determine an air speed value according to the current indoor temperature value t a . In some embodiments, when the air conditioner starts the PMV function, the air conditioner indoor fan is in the anti-direct-blowing speed, and the air speed value V can be determined as 0.3 m / s, or the maximum V can be determined as 0.5 m / s. The air conditioner can obtain a current indoor humidity value RH by humidity collection, or directly default the current indoor humidity value RH = 50%. The air conditioner can also read a current average radiant temperature value t r by an infrared sensor, and of course, the current average radiant temperature value t r may be equal to the current indoor temperature value t a by default. The air conditioner can obtain the second current parameter value. Alternatively, the air conditioner reports the second current parameter value to the cloud server after obtaining the second current parameter value.

[0072] After the air conditioner or the cloud server obtains the first current parameter value and the second current parameter value, the third current parameter value can be determined, wherein the process of determining the current clothing surface area coefficient f el includes: when I cl ≤ 0.078, f cl = 1.0 + 1.290 I cl ; when I cl > 0.078, f cl = 1.05 + 0.645 I cl . The process of determining the current water vapor partial pressure P a includes: The process of determining the current clothing surface temperature value t el includes: t cl = 35.7 - 0.028 (M-W) - Icl·[3.96×10 -8 f cl × {(t cl + 273) 4 - (t r + 273) 4} + f cl h c (t cl - t a )]. The process of determining the current convective heat transfer coefficient h c includes:

[0073] After determining the third parameter, a current PMV value calculation formula matching the current clothes belonging to the crowd information can be determined, wherein in some embodiments, determining the current PMV value calculation formula matching the current clothes belonging to the crowd information includes: in the case that the current clothes belonging to the crowd information is male, determining formula (1) as the current PMV value calculation formula; in the case that the current clothes belonging to the crowd information is female, determining formula (2) as the current PMV value calculation formula.

[0074] PMV_male = (0.303e -0.036M +0.016){(M-W)-3.05×10 -3 ×[5733-6.99(M-W)-P a ]-0.42×[(M-W)-58.15]-1.7×10 -5 M(5867-P a )-0.0014M(34-t a )-3.96×10 -8 f cl ×[(t cl +273) 4 -(t r +273) 4 ]-f cl h c (t cl -t a )}-0.050 (1);

[0075] PMV_female = (0.303e -0.036M +0.033){(M-W)-3.05×10 -3 ×[5733-6.99(M-W)-P a ]-0.42×[(M-W)-58.15]-1.7×10 -5 M(5867-P a )-0.0014M(34-t a )-3.96×10 -8 f cl ×[(t cl +273) 4 -(t r +273) 4 ]-f cl h c (t cl -t a )}-0.227 (2);

[0076] wherein M is the metabolic rate of the human body, W is the external mechanical work, P a is the water vapor pressure, ta is the indoor temperature value, f el is the clothing surface area coefficient, t el is the clothing surface temperature value, t r is the average radiant temperature value, h c is the convective heat exchange coefficient.

[0077] The air conditioner or the cloud server can determine the current PMV value according to M, W, P a , t a , f el , t el , t r , h c , and formula (1) or formula (2).

[0078] Step 203: Control the air conditioner to operate according to the current comfort PMV value.

[0079] In some embodiments, when the current comfort PMV value is greater than the upper limit value of the set comfort interval, a first control instruction is sent to the air conditioner to reduce the target temperature by a set temperature, so that the air conditioner operates according to the first control instruction; when the current comfort PMV value is less than the lower limit value of the set comfort interval, a second control instruction is sent to the air conditioner to increase the target temperature by a set temperature, so that the air conditioner operates according to the second control instruction.

[0080] For example, the set comfort interval is [-0.5, 0.5], so the upper limit value is 0.5 and the lower limit value is -0.5. If the current PMV value > 0.5, the air conditioner determines a first control instruction to reduce the target temperature by 0.5°C, and operates according to the first control instruction, or the cloud server determines a first control instruction to reduce the target temperature by 0.5°C and sends it to the air conditioner, and the air conditioner operates according to the first control instruction.

[0081] If the current PMV value is < -0.55, the air conditioner determines a first control instruction to increase the target temperature by 0.5°C, and operates according to the first control instruction, or the cloud server determines a first control instruction to increase the target temperature by 0.5°C and sends it to the air conditioner, and the air conditioner operates according to the first control instruction. That is, the air conditioner realizes automatic PMV mode operation of setting the target temperature.

[0082] It can be seen that in the embodiment, the factors affecting the PMV control of the air conditioner can be directly obtained by the NFC tag, and the corresponding PMV value can be obtained, and the operation of the air conditioner is controlled according to the PMV value, so that the PMV control process of the air conditioner is more easily realized, and the universality of the PMV application of the air conditioner is improved. Moreover, the information carried by the NFC tag of the clothes can be directly collected, and the information collected by other household appliances and language devices is more accurate and has lower cost, thereby further improving the accuracy of the PMV control of the air conditioner and reducing the cost of the air conditioner control.

[0083] The operation flow is combined into the specific embodiment below to illustrate the air conditioner control process provided by the embodiment of the present application.

[0084] In an embodiment of the present disclosure, a system for air conditioner control is shown in Figure 1 , the cloud server can communicate with the air conditioner and the terminal respectively, and the terminal has the function of scanning the NFC tag. The cloud server can save the corresponding relationship shown in Table 2, save the formula (1) and formula (2). Moreover, the metabolic rate of human body is configured as 70w / m 2 , the mechanical function W outside is 0w / m 2 , and the air speed value v is 0.3m / s.

[0085] Figure 3 is a flowchart of an air conditioner control method provided by an embodiment of the present disclosure. As shown in Figure 3 , the air conditioner control process includes:

[0086] Step 301: The cloud server receives the current clothes information reported by the terminal after reading the near field communication NFC tag on the current user's clothes in the action area of the air conditioner.

[0087] Step 302: Whether the cloud server receives the PMV instruction sent by the air conditioner? If yes, execute step 303, otherwise, return to step 301.

[0088] Step 303: The cloud server obtains the first current parameter information of the current user from the current clothes information. The first current parameter information includes: current clothes category information and current clothes belonging to the crowd information.

[0089] Step 304: The cloud server obtains the second current parameter value reported by the air conditioner, wherein the second current parameter value includes: the current indoor temperature value t a , the current indoor humidity value RH, and the current mean radiant temperature value t r .

[0092] Step 307: The cloud server determines the current comfort PMV value through the current PMV value calculation formula according to the second current parameter value and the third current parameter value.

[0117] In some embodiments, the control module 430 includes:

[0118] The first control unit is configured to send a first control command to the air conditioner to lower the target temperature to the set temperature when the current comfort PMV value is greater than the upper limit of the set comfort range, so that the air conditioner operates according to the first control command.

[0119] The second control unit is configured to send a second control command to the air conditioner to raise the target temperature to the set temperature when the current comfort PMV value is less than the lower limit of the set comfort range, so that the air conditioner operates according to the second control command.

[0120] The air conditioning control process for the air conditioning control device is further described below with reference to embodiments.

[0121] In this embodiment, the system used for air conditioning control is as follows: Figure 1 As shown, the cloud server can communicate with both the air conditioner and the terminal, and the terminal has the function of scanning NFC tags. Furthermore, it is configured with a human metabolic rate of 70w / m³. 2 External mechanical function W = 0w / m 2 The air velocity value is v = 0.5 m / s.

[0122] Figure 5is a structural schematic diagram of an air conditioner control device provided by an embodiment of the present disclosure. As shown in Figure 5 The air conditioner control device 400 includes an acquisition module 410, a determination module 420, a control module 430, and a storage module 440. The determination module 420 includes an acquisition unit 421, a first determination unit 422, a second determination unit 423, and a third determination unit 424. The control module 430 includes a first control unit 431 and a second control unit 432.

[0123] In this embodiment, the storage module 440 stores the correspondence relationship shown in Table 2, and stores formula (1) and formula (2). In this way, after receiving the current clothing information reported by the terminal after reading the near field communication (NFC) tag on the current clothing of the user in the action area of the air conditioner, if the PMV instruction sent by the air conditioner is received, the acquisition module 410 can acquire the first current parameter information of the current user from the current clothing information. The first current parameter information includes current clothing category information and current clothing population information.

[0124] Therefore, the acquisition unit 421 in the determination module 420 can acquire the second current parameter value reported by the air conditioner, wherein the second current parameter value includes the current indoor temperature value t a , the current indoor humidity value RH, and the current mean radiant temperature value t r . Therefore, the first determination unit 422 can determine the current clothing thermal resistance value l cl corresponding to the current clothing category information and the current clothing population information according to Table 2, and determine the third current parameter value according to the current clothing thermal resistance value l cl , the current indoor temperature value t a , the current indoor humidity value RH, and the air speed value v, including the current clothing surface area coefficient f el , the current clothing surface temperature value t el , the current convective heat exchange coefficient h c , and the current water vapor partial pressure P a . The second determination unit 423 determines formula (1) or formula (2) as the current PMV value calculation formula according to the current clothing population information. Therefore, the third determination unit 424 determines the current comfort PMV value according to the second current parameter value, the third current parameter value, and the current PMV value calculation formula.

[0125] If the current PMV value is greater than 0.5, the first control unit 431 in the control module 430 determines the instruction of the target temperature -0.5℃ as the first control instruction, and sends it to the air conditioner, so that the air conditioner operates according to the first control instruction; and when the current PMV value is less than -0.5, the second control unit 432 in the control module 430 determines the instruction of the target temperature +0.5℃ as the first control instruction, and sends it to the air conditioner, so that the air conditioner operates according to the first control instruction. Of course, when the current PMV value is between [-0.5, 0.5], the control module 430 determines the instruction of the target temperature unchanged as the first control instruction, and sends it to the air conditioner, so that the air conditioner operates according to the first control instruction.

[0126] It can be seen that in the embodiment, the device for air conditioner control can obtain the factors affecting the PMV control of the air conditioner through the NFC tag directly, and obtain the corresponding PMV value, and then control the operation of the air conditioner according to the PMV value, so that the PMV control process of the air conditioner is easier to realize, and the universality of the PMV application of the air conditioner is improved. Moreover, the information carried by the clothes NFC tag can be collected more accurately and at a lower cost through other household electrical appliances and language devices, further improving the accuracy of the PMV control of the air conditioner and reducing the cost of the air conditioner control.
