Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to an indoor temperature estimation method, an air conditioning system and a computer storage medium. Background Art

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] The air conditioning system needs to control the operation of the air conditioner according to the indoor ambient temperature. Based on the influence of factors such as climate and building structure, in the existing market, such as some air conditioning systems in North America, the air conditioner is placed in the attic or basement of the building, and an air supply duct is laid to transport the cold air or hot air generated by the air conditioner to the bedroom. Therefore, the distance between the air conditioner and the bedroom is far, and there is a certain deviation between the return air temperature of the air conditioner and the indoor temperature. Usually, the above-mentioned equipment obtains the indoor temperature by obtaining the temperature of the environment where the control device such as the wire controller in the bedroom is located. However, many control devices such as wire controllers on the market currently communicate wirelessly with the air conditioner in the form of phone cards. Since the communication between the wire controller and the air conditioner consumes traffic, the indoor temperature measured by the wire controller cannot be transmitted to the air conditioner in real time, which makes the acquisition of the indoor temperature delayed, or the communication between the wire controller and the air conditioner is easily interrupted, resulting in failure to obtain the indoor temperature. Summary of the invention

[0004] The purpose of the present invention is to at least solve the problem of delay or failure of the air conditioner to obtain the indoor temperature. This purpose is achieved by the following technical solutions:

[0005] The first aspect of the present invention proposes a method for estimating indoor temperature, wherein the air-conditioning system includes an air conditioner and a control device connected by wireless communication, and the estimation method includes: obtaining a temperature compensation value; obtaining a first temperature of the environment in which the air conditioner is located based on the interruption of wireless communication between the air conditioner and the control device; and determining that the sum of the first temperature and the temperature compensation value is the indoor temperature.

[0006] According to the indoor temperature estimation method of the present invention, when the wireless communication connection between the control device and the air conditioner is interrupted, the first temperature of the environment in which the air conditioner is located plus the temperature compensation value is used as the estimated value of the indoor temperature, so as to provide a reference value of the indoor temperature for the operation of the air conditioner, thereby solving the problem of delayed or failed indoor temperature acquisition during communication interruption. Moreover, the estimated value of the indoor temperature is closer to the actual value of the indoor temperature relative to the first temperature of the environment in which the air conditioner is located, so that the operation of the air conditioner is closer to the actual needs of the user and the accuracy of automatic control of the air conditioner operation is improved.

[0007] In addition, the inference method according to the present invention may also have the following additional technical features:

[0008] In some embodiments of the present invention, the step of obtaining the temperature compensation value includes: obtaining in real time a second temperature of the environment in which the air conditioner is located and a third temperature of the environment in which the control device is located based on the wireless communication between the air conditioner and the control device; calculating a first difference between the third temperature and the second temperature; and determining the temperature compensation value based on the first difference.

[0009] In some embodiments of the present invention, the step of determining the temperature compensation value based on the first difference includes: obtaining the starting time when the wireless communication between the air conditioner and the control device is interrupted; and determining the first difference at the moment before the starting time as the temperature compensation value.

[0010] In some embodiments of the present invention, the estimation method also includes: obtaining a first value of the indoor temperature at the starting time; obtaining a second value of the indoor temperature after the starting time in real time; calculating a second difference between the second value and the first value; assigning the temperature compensation value to 0 based on the absolute value of the second difference being greater than a first preset value, and determining that the sum of the first temperature and the temperature compensation value is the indoor temperature; and determining that the first difference at the moment before the starting time is the temperature compensation value based on the absolute value of the second difference being less than or equal to the first preset value.

[0011] In some embodiments of the present invention, after the step of obtaining the starting moment of the interruption of wireless communication between the air conditioner and the control device, the step also includes: obtaining the interruption duration of the wireless communication between the air conditioner and the control device; assigning the temperature compensation value to 0 based on the interruption duration being greater than the first time setting value; and determining the first difference before the starting moment as the temperature compensation value based on the interruption duration being less than or equal to the first time setting value.

[0012] In some embodiments of the present invention, after the step of obtaining the starting moment of the interruption of wireless communication between the air conditioner and the control device, the step also includes: obtaining a first numerical value T1 of the first temperature at the starting moment; obtaining a second numerical value T2 of the first temperature at a first time t from the starting moment; calculating the temperature change rate of the first temperature according to the formula (T2-T1) / t; assigning the temperature compensation value to 0 according to the absolute value of the temperature change rate being greater than a second preset value; and determining that the first difference at the moment before the starting moment is the temperature compensation value according to the absolute value of the temperature change rate being less than or equal to the second preset value.

[0013] In some embodiments of the present invention, the step of calculating the first difference between the third temperature and the second temperature further includes: recording mapping relationship data between the second temperature and the first difference within at least one operating cycle based on the second temperature and the first difference; obtaining a first mapping relationship of the mapping relationship data within the operating cycle closest to the current moment; and determining, based on the first mapping relationship, that the first difference corresponding to the first temperature at the current moment is the temperature compensation value.

[0014] In some embodiments of the present invention, the operation cycle includes at least one of the following: an operation time cycle of the air-conditioning system, a value change cycle of the second temperature.

[0015] According to the second aspect of the present invention, an air-conditioning system is also proposed, which includes: an air conditioner, a return air outlet of the air conditioner is provided with a first temperature sensor; a control device, which is wirelessly connected to the air conditioner, and the control device is provided with a second temperature sensor; a control device, which is arranged in the air conditioner and is respectively connected to the air conditioner and the control device, and the control device is used to execute the indoor temperature estimation method described in the technical solution of the first aspect.

[0016] According to a third aspect of the present invention, a computer storage medium is further proposed, on which computer-readable instructions are stored. When the computer-readable instructions are executed by one or more processors, the one or more processors execute the indoor temperature estimation method as described in any one of the technical solutions of the first aspect.

[0026] It should be understood that the terms used herein are only for the purpose of describing specific example embodiments and are not intended to be limiting.

[0027] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text.

[0028] For ease of description, spatial relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure.

Therefore, the example term "below..." can include both upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0029] like Figure 1 As shown, according to an embodiment of the present invention, a method for estimating indoor temperature is proposed. The estimating method is applied to an air-conditioning system and provides the estimated indoor temperature value to the air-conditioning system, thereby providing data support for the air-conditioning system to solve the problem that the air-conditioner cannot obtain indoor temperature data or obtains indoor temperature data with lag when the communication between the air-conditioner and the control device is interrupted. Specifically, the estimating method includes the following steps:

[0030] Step S101: acquiring a first temperature of an environment where the air conditioner is located according to the interruption of wireless communication between the air conditioner and the control device;

[0031] Step S102: obtaining a temperature compensation value;

[0032] Step S103: Determine that the sum of the first temperature and the temperature compensation value is the indoor temperature.

[0033] In this embodiment, based on factors such as climate and building structure, the air conditioner and control device in the air conditioning system are respectively arranged in different spaces. For example, the control device is generally placed in the bedroom for user convenience, and the air conditioner is placed in the attic or basement so that the air conditioner and the control device are far apart, and an air supply duct is arranged between the air conditioner and the control device to deliver the cold air or hot air generated by the air conditioner to the bedroom. Since the air conditioner and the control device are separated by building structures such as walls, in order to facilitate the placement of the air conditioning system and save installation costs such as avoiding drilling holes in the wall and threading wires, the control device and the air conditioner are connected by wireless communication by inserting a phone card, and data transmission between the control device and the air conditioner is achieved by consuming billing traffic, and the user can issue control instructions to the air conditioner by operating the control device in a space such as a bedroom to control the operation of the air conditioner. In this embodiment, the control device includes but is not limited to a wire controller, a remote controller, etc.

[0034] It is understandable that since the air conditioner and the control equipment are respectively installed in different building spaces, there must be differences in the ambient temperature in different building spaces. Especially when the air conditioner is in continuous operation, the air conditioner continuously supplies cold air or hot air to the bedroom through the air supply duct, which will cause the indoor temperature in the bedroom to be significantly different from the ambient temperature of the air conditioner.

[0035] When the wireless communication between the air conditioner and the control device is connected, the temperature of the environment where the control device is located is the indoor temperature. The temperature detected by the control device is transmitted to the air conditioner through wireless communication to provide data support for the indoor temperature for the operation of the air conditioner.

[0036] When the wireless communication connection between the air conditioner and the control device is interrupted, the ambient temperature in the bedroom detected by the control device cannot be transmitted to the air conditioner. At this time, according to the temperature difference between the environment in which the air conditioner is located and the environment in which the control device is located, a temperature compensation value is obtained. When the wireless communication connection between the air conditioner and the control device is interrupted, the first temperature of the environment in which the air conditioner is located is obtained. The first temperature can be the return air temperature detected at the return air outlet of the air conditioner, or it can be the ambient temperature detected by a temperature sensor arranged on the side of or near the air conditioner. The sum of the first temperature and the temperature compensation value is used as the estimated value of the indoor temperature at this time. Real-time correction is performed based on the real-time temperature value of the air conditioner to obtain the real-time indoor temperature, so as to provide a reference value of the indoor temperature for the operation of the air conditioner, solve the problem of delay or failure in obtaining the indoor temperature during the communication process, and the estimated value of the indoor temperature is closer to the actual value of the indoor temperature than the first temperature of the environment in which the air conditioner is located, so that the operation of the air conditioner is closer to the actual needs of the user and the accuracy of automatic control of the air conditioner operation is improved.

[0037] It should be noted that, in the present embodiment, there are multiple ways to obtain the temperature compensation value. For example, the temperature compensation value can be calculated based on the real-time temperature value of the environment in which the air conditioner is located and the temperature value of the environment in which the control device is located; or, the temperature compensation value can be calculated based on the historical record data of the ambient temperature of the air conditioner (such as the ambient temperature in the attic) and the ambient temperature of the control device (such as the ambient temperature in the bedroom). In the present embodiment, there is no specific limitation on the way to obtain the temperature compensation value.

[0038] like Figure 2 As shown, according to some embodiments of the present invention, the inference method includes the following steps:

[0039] Step S201: acquiring in real time a second temperature of an environment where the air conditioner is located and a third temperature of an environment where the control device is located according to wireless communication between the air conditioner and the control device;

[0040] Step S202: Calculate a first difference between the third temperature and the second temperature;

[0041] Step S203: acquiring a first temperature of an environment where the air conditioner is located according to the interruption of wireless communication between the air conditioner and the control device;

[0042] Step S204: obtaining the start time of the interruption of the wireless communication between the air conditioner and the control device;

[0043] Step S205: determining the first difference at a moment before the starting moment as the temperature compensation value;

[0044] Step S206: Determine that the sum of the first temperature and the temperature compensation value is the indoor temperature.

[0045] In this embodiment, in step S201, when the wireless communication between the air conditioner and the control device remains connected, the second temperature data of the environment in which the air conditioner is located is obtained in real time, and the third temperature data of the environment in which the control device is located is obtained in real time, wherein the second temperature data is obtained by detecting by a first temperature sensor arranged at the return air outlet of the air conditioner, and the third temperature data is obtained by detecting by a second temperature sensor arranged in the control device.

[0046] In step S202, by calculating in real time the first difference between the third temperature and the second temperature, the temperature difference between the ambient temperature of the control device (such as the ambient temperature in the bedroom) and the ambient temperature of the air conditioner (such as the ambient temperature in the attic) can be obtained, and a data set of the first difference between the third temperature and the second temperature during the period when the wireless communication between the air conditioner and the control device remains connected can be obtained.

[0047] In step S204 to step S205, by obtaining the start time of the wireless communication interruption between the air conditioner and the controller, taking the start time as the reference point of time, and determining the first difference value before the start time as the temperature compensation value, the temperature compensation value determined is closest to the temperature difference value of the actual indoor temperature (i.e., the ambient temperature in the bedroom) at the current moment minus the temperature of the air conditioner, and has a small error. In step S203 and step S206, when the wireless communication between the air conditioner and the control device is interrupted, the estimated indoor temperature can be obtained by adding the temperature compensation value according to the first temperature of the environment where the air conditioner is located, so that the estimated indoor temperature is closer to the actual indoor temperature, so as to improve the control accuracy of the air conditioner during operation.

[0048] Among them, in this embodiment, the moment immediately before the starting moment refers to the moment with a time interval t1 from the starting moment, and the value range of the time interval t1 is 0 < t1 < 10 s. Understandably, t1 can take a time value infinitely close to 0 to ensure that the temperature compensation value is the first difference calculated from the data of the third temperature and the second temperature transmitted most recently before the starting moment.

[0049] As Figure 3 shown, according to some embodiments of the present invention, the estimation method specifically includes the following steps:

[0050] Step S301: According to the wireless communication connection between the air conditioner and the control device, obtain the second temperature of the environment where the air conditioner is located and the third temperature of the environment where the control device is located in real time;

[0051] Step S302: Calculate the first difference obtained by subtracting the second temperature from the third temperature;

[0052] Step S303: According to the wireless communication interruption between the air conditioner and the control device, obtain the first temperature of the environment where the air conditioner is located;

[0053] Step S304: Obtain the starting moment of the wireless communication interruption between the air conditioner and the control device;

[0054] Step S305: Determine the first difference at the moment immediately before the starting moment as the temperature compensation value; Step S306: Determine the sum of the first temperature and the temperature compensation value as the indoor temperature;

[0055] Step S307: Obtain the first value of the indoor temperature at the starting moment;

[0056] Step S308: Obtain the second value of the indoor temperature in real time after the starting moment;

[0057] Step S309: Calculate the second difference obtained by subtracting the first value from the second value;

[0058] Step S310: Determine whether the absolute value of the second difference is greater than the first preset value. If so, assign the temperature compensation value to 0 and execute step S306. If not, execute step S305.

[0059] In this embodiment, steps S301 to S306 are the same as steps S201 to S206, and will not be elaborated here.

[0060] In step S307, when the wireless communication connection between the air conditioner and the control device is interrupted, the first temperature of the environment where the air conditioner is located at the start time is obtained, and the first value of the indoor temperature estimated at the start time is obtained based on the sum of the first temperature and the temperature compensation value. After the start time, in steps 308 to S309, the second value of the indoor temperature is obtained in real time, and the second difference between the second value and the first value is calculated. The change of the estimated indoor temperature since the start time of the wireless communication connection interruption can be seen according to the absolute value of the second difference. The larger the absolute value of the second difference, the greater the change of the estimated indoor temperature.

[0061] In step S310, if the absolute value of the second difference is greater than the first preset value, it means that the current estimated indoor temperature is significantly different from the indoor temperature at the starting time. At this time, the ambient temperature of the air conditioner (i.e., the first temperature) changes greatly, and the accuracy of the second numerical value of the currently estimated indoor temperature is poor. Therefore, the temperature compensation value is assigned to 0, and the first temperature of the temperature environment currently measured in which the air conditioner is located is taken as the indoor temperature for reference for the operation of the air conditioner.

[0062] If the absolute value of the second difference is less than or equal to the first preset value, it means that the current estimated indoor temperature is smaller than the indoor temperature at the starting moment. At this time, the ambient temperature of the air conditioner (i.e., the first temperature) changes less. It is determined that the second numerical value of the currently estimated indoor temperature is accurate. The temperature compensation value is still assigned according to the steps in step S304, that is, the temperature compensation value is assigned to the first difference before the starting moment, and the indoor temperature is estimated based on the temperature compensation value and the sum of the first temperature to obtain a more accurate estimated value of the indoor temperature.

[0063] In this embodiment, the value range of the first preset value a is 2°F≤a≤6°F. For example, the first preset value can be 2°F, 2.5°F, 3°F, 3.5°F, 4°F, etc.

[0064] like Figure 4 As shown, according to some embodiments of the present invention, the inference method specifically includes the following steps:

[0065] Step S401: acquiring in real time a second temperature of the environment where the air conditioner is located and a third temperature of the environment where the control device is located according to the wireless communication connection between the air conditioner and the control device;

[0066] Step S402: Calculate a first difference between the third temperature and the second temperature;

[0067] Step S403: acquiring a first temperature of an environment where the air conditioner is located according to the interruption of wireless communication between the air conditioner and the control device;

[0068] Step S404: obtaining the start time of the interruption of the wireless communication between the air conditioner and the control device;

[0069] Step S405: obtaining the interruption duration of the wireless communication interruption between the air conditioner and the control device;

[0070] Step S406: determine whether the interruption duration is greater than the first time setting value, if yes, assign the temperature compensation value to 0, if no, execute step S407;

[0071] Step S407: determining the first difference at a moment before the starting moment as the temperature compensation value;

[0072] Step S408: Determine that the sum of the first temperature and the temperature compensation value is the indoor temperature.

[0073] In this embodiment, steps S401 to S404 are the same as steps S201 to S204, and steps S407 to S408 are the same as steps S205 to S206, which will not be repeated here.

[0074] In step S405 to step S406, the interruption duration of the wireless communication interruption is the duration of the wireless communication interruption between the air conditioner and the control device from the start time of the wireless communication interruption. The longer the interruption duration is, the longer the duration of the wireless communication interruption is. Since the air conditioner and the control device are respectively located in different building spaces, affected by environmental factors and the air conditioner's own operating factors, when the interruption duration of the wireless communication interruption is greater than the first time setting value, it means that the ambient temperature of the space where the air conditioner is located (i.e., the first temperature) and the ambient temperature of the space where the control device is located (i.e., the actual value of the indoor temperature) have changed greatly, so that when the temperature compensation value is assigned to the first difference, the estimated indoor temperature has seriously deviated from the actual value of the indoor temperature, resulting in poor accuracy of the estimated indoor temperature. Therefore, the temperature compensation value is assigned to 0, and in the wireless communication interruption state, the first temperature of the environment where the air conditioner is located is used as the estimated indoor temperature.

[0075] When the interruption duration of wireless communication is less than or equal to the first time setting value, it means that the change between the ambient temperature of the space where the air conditioner is located (i.e., the first temperature) and the ambient temperature of the space where the control device is located (i.e., the actual value of the indoor temperature) is small, so that when the temperature compensation value is assigned to the first difference, the estimated indoor temperature is closer to the actual value of the indoor temperature, so the estimated indoor temperature is accurate. When the wireless communication is interrupted, the sum of the first temperature and the temperature compensation value is used as the value of the indoor temperature to ensure that the indoor temperature calculated according to the indoor temperature estimation method has high accuracy.

[0076] In some implementations, the value range of the first time setting value t2 is 0.5 hour ≤ t2 ≤ 1 hour. For example, the first time setting value can be set to 0.5 hour, 0.8 hour, 1 hour, etc.

[0077] In some implementations, the value range of the first time setting value t2 is 10 minutes ≤ t2 ≤ 30 minutes. For example, the first time setting value can be set to 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, etc.

[0078] In other implementations, the value range of the first time setting value t2 is 1 hour ≤ t2 ≤ 24 hours. For example, the first time setting value can be set to 1 hour, 2 hours, 3 hours, 10 hours, 20 hours, etc.

[0079] It should be noted that the first time setting value can be adjusted according to different regions, different seasons, different building structure types or different user habits, etc. For example, in low-latitude areas close to the equator, the daily temperature difference is small, so the first time setting value can be set to a larger value, such as 10 hours, 15 hours, 20 hours, etc.; in spring or autumn in high-latitude areas, the temperature difference between day and night is large, and factors such as external environmental temperature changes and light also have a greater impact on the interior of the building structure, so the first time setting value can be set to a smaller value, such as 1 hour, 2 hours, 3 hours, 5 hours, etc.

[0080] According to some embodiments of the present invention, the inference method specifically comprises the following steps:

[0081] Step S501: acquiring in real time the second temperature of the environment where the air conditioner is located and the third temperature of the environment where the control device is located according to the wireless communication connection between the air conditioner and the control device;

[0082] Step S502: calculating a first difference between the third temperature and the second temperature;

[0083] Step S503: acquiring a first temperature of an environment where the air conditioner is located according to the interruption of wireless communication between the air conditioner and the control device;

[0084] Step S504: obtaining the start time of the interruption of the wireless communication between the air conditioner and the control device;

[0085] Step S505: obtaining a first value T1 of a first temperature at a starting time;

[0086] Step S506: obtaining a second value T2 of the first temperature at a first time t from the start time;

[0087] Step S507: Calculate the temperature change rate of the first temperature according to the formula (T2-T1) / t;

[0088] Step S508: determine whether the absolute value of the temperature change rate is greater than a second preset value, if so, assign the temperature compensation value to 0, if not, execute step S509;

[0089] Step S509: determining the first difference at a moment before the starting moment as the temperature compensation value;

[0090] Step S510: Determine that the sum of the first temperature and the temperature compensation value is the indoor temperature.

[0091] In this embodiment, steps S501 to S504 are the same as steps S201 to S204, and steps S509 to S510 are the same as steps S205 to S206, which will not be repeated here.

[0092] In step S505 to step S508, since the wireless communication is interrupted, as the air conditioner continues to run and continuously outputs cooling or heat to the bedroom, the ambient temperature of the environment in which the air conditioner is located and the ambient temperature of the environment in which the control device is located will change. In this process, the first value T1 of the first temperature of the environment in which the air conditioner is located at the starting time is first recorded, and the time interval t (i.e., the first time) from the current time to the starting time, and the second value T2 of the first temperature of the environment in which the air conditioner is located at the current time are obtained. The formula (T2-T1) / t can calculate the temperature change rate of the first temperature of the room. If the absolute value of the temperature change rate of the first temperature is greater than the second preset value, it means that the change rate of the first temperature is large during the time period from the first time t to the starting time. If the estimated indoor temperature is still calculated based on the sum of the first difference and the first temperature, there is a large error. Therefore, the temperature compensation value is assigned to 0. When the wireless communication is interrupted, the first temperature of the environment in which the air conditioner is located is used as the estimated indoor temperature.

[0093] If the absolute value of the temperature change rate of the first temperature is less than or equal to the second preset value, it means that in the time period from the first time t to the starting time, the change rate of the first temperature is small, and the estimated indoor temperature based on the first difference and the sum of the first temperature is more accurate. Therefore, when the wireless communication is interrupted, the temperature compensation value is assigned to the first difference, and the sum of the first temperature and the temperature compensation value is used as the value of the indoor temperature to ensure that the indoor temperature calculated according to the indoor temperature estimation method has higher accuracy.

[0094] According to some embodiments of the present invention, the inference method specifically comprises the following steps:

[0095] Step S601: acquiring in real time the second temperature of the environment where the air conditioner is located and the third temperature of the environment where the control device is located according to the wireless communication connection between the air conditioner and the control device;

[0096] Step S602: Calculate a first difference between the third temperature and the second temperature;

[0097] Step S603: acquiring a first temperature of an environment where the air conditioner is located according to the interruption of wireless communication between the air conditioner and the control device;

[0098] Step S604: recording mapping relationship data between the second temperature and the first difference within at least one operation cycle according to the second temperature and the first difference;

[0099] Step S605: Acquire a first mapping relationship of mapping relationship data in an operation cycle closest to the current moment;

[0100] Step S606: determining, according to the first mapping relationship, a first difference corresponding to the first temperature at the current moment as a temperature compensation value;

[0101] Step S607: Determine that the sum of the first temperature and the temperature compensation value is the indoor temperature.

[0102] In this embodiment, steps S601 to S602 are the same as steps S201 to S202, and steps S606 are the same as steps S206, which are not described in detail here.

[0103] In step S604, by recording the temperature data of the third temperature and the second temperature when the air conditioner and the control device are in a wireless communication connection state, a one-to-one mapping relationship data of the second temperature and the first difference of at least one operating cycle can be obtained, wherein the operating cycle can be the operating time cycle of the air-conditioning system, or the numerical change cycle of the second temperature.

[0104] In some embodiments, the operating cycle is set to the operating time cycle of the air-conditioning system. For example, the operating time cycle of the air-conditioning system is one day, that is, from 0:00 to 24:00. In this embodiment, the mapping relationship data between the second temperature and the first difference within at least one operating cycle is collected from 0:00 to 24:00 at each moment in at least one day. The data of the third temperature, the second temperature and the first difference obtained by subtracting the second temperature from the third temperature are collected. The one-to-one correspondence between the second temperature and the first difference obtained based on the collected data is the mapping relationship data.

[0105] In some embodiments, the operating cycle is a cycle of value change of the second temperature. Since the value of the second temperature changes from low to high and then from high to low during the operation of the air-conditioning system, when the value of the second temperature rises from the lowest value to the highest value and then falls back to the lowest value, it is an operating cycle, or when the value of the second temperature drops from the highest value to the lowest value and then rises back to the highest value, it is an operating cycle. Data on the third temperature corresponding to each second temperature value and the first difference obtained by subtracting the second temperature from the third temperature are collected, and the one-to-one correspondence between the second temperature and the first difference obtained based on the collected data is the mapping relationship data.

[0106] It is understandable that if in one operation cycle, when the second temperature has the same value in different stages and corresponds to different first differences, the average value of the different first differences is taken as the data corresponding to the second temperature.

[0107] In step S605 to step S606, by obtaining the first mapping relationship of the mapping relationship data in the operating cycle closest to the current moment, the environmental factors in the obtained first mapping relationship are made closest to the state at the current moment to reduce the impact of the environmental factors on the estimated results, and the first difference corresponding to the first temperature at the current moment is determined according to the first mapping relationship, and the first difference is used as the temperature compensation value to reduce the error of the numerical value of the estimated indoor temperature.

[0108] According to an embodiment of the present invention, an air conditioning system is also provided. Figure 5 As shown, the air conditioning system includes: an air conditioner 10 , a control device 20 and a control apparatus 30 .

[0109] The return air outlet of the air conditioner 10 is provided with a first temperature sensor 11, which is used to detect a first temperature when the air conditioner 10 and the control device 20 are in a wireless communication interruption state. The first temperature sensor 11 is also used to detect a second temperature when the air conditioner 10 and the control device 20 are in a wireless communication connection state.

[0110] The control device 20 is provided with a second temperature sensor 21, and the second temperature sensor 21 is also used to detect a third temperature when the air conditioner 10 and the control device 20 are in a wireless communication connection state.

[0111] The control device 30 is arranged on the air conditioner 10 and is communicatively connected with the air conditioner 10 and the control device 20 respectively. The control device 20 transmits the third temperature to the control device 30 by wireless communication. The control device 30 is used to obtain the temperature compensation value, obtain the first temperature according to the interruption of the wireless communication between the air conditioner 10 and the control device 20, and determine that the sum of the first temperature and the temperature compensation value is the indoor temperature, thereby calculating the specific value of the indoor temperature, providing data support for the operation of the air conditioner 10.
