[0002] When the air conditioner leaves the factory, the operating capacity, such as cooling capacity / heating capacity, is already fixed. Users generally choose an air conditioner with a matching operating capacity based on the size of the room or their own needs. However, in actual applications, different users have different requirements for operating capacity, and the environment in which the air conditioner is located is complex and changeable, so there may be a situation where the current operating capacity of the air conditioner cannot meet the user's needs. When this happens, the user can only replace the air conditioner or contact after-sales service for a door-to-door solution. The operation process is cumbersome and affects the use effect of the air conditioner.

[0003] The above contents are only used to assist in understanding the technical solution of the present invention and do not constitute an admission that the above contents are prior art. Summary of the invention

[0004] The main purpose of the present invention is to provide a method, device and computer-readable storage medium for upgrading the operating capacity of an air conditioner, aiming to automatically upgrade the operating capacity of the air conditioner through OTA based on user needs, without replacing the air conditioner or after-sales on-site solution, thereby improving the use effect of the air conditioner.

[0005] To achieve the above object, the present invention provides a method for upgrading the operating capacity of an air conditioner, the method comprising the following steps:

[0006] Get the historical operation data of the air conditioner;

[0007] Determining whether the current operating capacity of the preset operating mode matches the required operating capacity based on the historical operating data;

[0008] When the current operating capability of the preset operating mode does not match the required operating capability, the operating capability of the preset operating mode is upgraded through OTA.

[0009] In one possible implementation, the step of upgrading the operating capability of the preset operating mode through OTA includes:

[0010] The performance parameters corresponding to the operating capability of the preset operating mode are upgraded through OTA to upgrade the operating capability of the preset operating mode.

[0011] In one possible implementation, the step of upgrading the performance parameters corresponding to the operating capability of the preset operating mode through OTA includes:

[0012] When the current operating capacity does not reach the required operating capacity, downloading a first performance parameter upgrade package to upgrade the performance parameter corresponding to the operating capacity of the preset operating mode so that the performance parameter increases;

[0013] When the required operating capacity is less than the current operating capacity, a second performance parameter upgrade package is downloaded to upgrade the performance parameters corresponding to the operating capacity of the preset operating mode, so that the performance parameters are reduced.

[0014] In one implementation, the step of determining whether the current operating capacity of the preset operating mode matches the required operating capacity according to the historical operating data includes:

[0015] Determining, based on the historical operation data, a demand preference for a current operation capacity relative to the operation mode, the demand preference comprising at least one of increased capacity, decreased capacity, and moderate capacity;

[0016] When the demand preference is capacity increase or capacity reduction, it is determined that the current operating capacity does not match the required operating capacity.

[0017] In one implementation, the step of determining the demand preference of the current operating capacity relative to the operating mode according to the historical operating data includes:

[0018] Determine, based on the historical operating data within a preset time period, a first proportion by which the set parameter exceeds a reference set range;

[0019] When the first ratio is greater than or equal to a preset threshold, the demand preference is determined to be a capacity increase or a capacity decrease.

[0020] In one implementation, the step of determining the demand preference of the current operating capacity relative to the operating mode according to the historical operating data includes:

[0021] Determine, based on the historical operation data within a preset time period, a second ratio of the time period for the air conditioner to reach a temperature exceeding a reference time period for reaching a temperature;

[0022] When the second ratio is greater than or equal to a preset threshold, the demand preference is determined to be a capacity increase or a capacity decrease.

[0023] In one possible implementation, after the step of upgrading the operating capability of the preset operating mode through OTA, the step further includes:

[0024] When the OTA upgrade fails, the timer starts;

[0025] When the timing duration reaches the preset duration, the process returns to the step of performing the step of upgrading the operating capability of the preset operating mode through OTA.

[0026] In one implementation, the air conditioner includes a plurality of devices, the devices including an outdoor unit and at least one indoor unit; when the current operating capacity of the preset operating mode does not match the required operating capacity, the step of upgrading the operating capacity of the preset operating mode through OTA includes:

[0027] When it is determined that there are multiple devices to be upgraded whose current operating capacity of the preset operating mode does not match the required operating capacity, determining an upgrade order according to the devices to be upgraded;

[0028] The operating capability of each device to be upgraded is upgraded in sequence through OTA according to the upgrade sequence.

[0029] The present invention also provides an air conditioner operating capacity upgrading device, which includes: a memory, a processor, and an operating capacity upgrading program stored in the memory and executable on the processor, wherein the operating capacity upgrading program implements the various steps of the air conditioner operating capacity upgrading method as described above when executed by the processor.

[0030] The present invention also provides a computer-readable storage medium, on which an operating capacity upgrade program is stored. When the operating capacity upgrade program is executed by a processor, the various steps of the air conditioner operating capacity upgrade method as described above are implemented.

[0031] The embodiments of the present invention propose a method, device and computer-readable storage medium for upgrading the operating capacity of an air conditioner. The method obtains the historical operating data of the air conditioner, and then determines the required operating capacity of the user based on the historical operating data. If the current operating capacity does not match the required operating capacity, the current operating capacity of the preset operating mode is upgraded through OTA to upgrade the operating capacity of the preset operating mode. Based on OAT technology, combined with automatic identification of the matching of the current operating capacity with user needs, the air conditioner is automatically upgraded without the need for after-sales door-to-door processing, and the operating capacity of the air conditioner is upgraded in a timely manner, so that the air conditioner can adapt to different environments or users, improve the use effect of the air conditioner, and enhance the user experience.

[0037] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0038] When the air conditioner leaves the factory, the operating capacity, such as cooling capacity / heating capacity, is already fixed. For example, when cooling, the maximum and minimum openings of the electronic expansion valve are fixed, and the maximum and minimum wind speeds are also fixed. The cooling capacity is limited to the capacity achieved within the performance parameter range.

[0039] In actual applications of air conditioners, different users have different requirements for operating capacity, and the environment where the air conditioner is located is complex and changeable (for example, the room size does not completely match the air conditioner's operating capacity, or the room is on the top floor and has different cooling or heating requirements than rooms on other floors, etc.). In this way, the current operating capacity of the air conditioner may not meet the user's needs. When this happens, the user can only replace the air conditioner or contact after-sales service for on-site solutions. The operation process is cumbersome, affecting the use effect of the air conditioner and providing a poor user experience.

[0040] With the advancement of technology, air conditioners can now remotely upgrade their firmware through Over-the-Air Technology (OTA) to continuously optimize the functions within the air conditioner. Therefore, OTA technology has been widely used. However, currently, air conditioners can only be upgraded OTA for functions, and cannot be upgraded for the cooling / heating capacity of the air conditioner.

[0041] Based on this, the present invention provides a method for upgrading the operating capacity of an air conditioner, which combines OTA technology to change the operating capacity of the air conditioner by upgrading the performance parameters corresponding to the operating parameters of the air conditioner, thereby realizing that the operating capacity changes according to the changes in user needs, or the same model of air conditioner can change its corresponding operating capacity according to the needs of different users, thereby increasing the use effect of the air conditioner and increasing universality.

[0042] In order to better understand the technical solutions provided by the embodiments of the present invention, exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0043] As an implementation method, the hardware environment architecture involved in the air conditioner operation capability upgrade method can be as follows: Figure 1 shown.

[0044] Optionally, the hardware architecture involved in the method for upgrading the operating capability of the air conditioner includes an air conditioner and / or a cloud server, wherein the cloud server upgrades the operating capability of the air conditioner via OTA.

[0045] As an implementation, the air conditioner or cloud server includes: a processor 101, such as a CPU, a memory 102, and a communication bus 103. The communication bus 103 is used to realize the connection and communication between these components. The processor 101 is used to call an application to perform an upgrade operation.

[0046] The memory 102 may be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory.

[0047] It can be understood that, in one embodiment, the operation capability upgrade program for implementing the function upgrade of the air conditioner is stored in the memory 102, or in a computer-readable storage medium, and when the processor 101 calls the operation capability upgrade program from the memory 102 or the computer-readable storage medium, the following operations are performed:

[0048] Get the historical operation data of the air conditioner;

[0049] Determining whether the current operating capacity of the preset operating mode matches the required operating capacity based on the historical operating data;

[0050] When the current operating capability of the preset operating mode does not match the required operating capability, the operating capability of the preset operating mode is upgraded through OTA.

[0051] First embodiment

[0052] Reference Figure 2 The present invention provides a method for upgrading the operating capacity of an air conditioner, the method comprising:

[0053] Step S10, obtaining historical operation data of the air conditioner;

[0054] The embodiment of the present invention is applied to upgrade the operating capability of the air conditioner through OTA. Optionally, the operating capability includes but is not limited to the cooling / heating capability of the air conditioner.

[0055] The cooling / heating capacity of the air conditioner is fixed when it leaves the factory. The cooling / heating capacity is determined based on the performance parameters. The performance parameter range of each air conditioner determines the cooling / heating capacity range of the air conditioner. During the operation of the air conditioner, the indoor air is adjusted based on the cooling / heating capacity corresponding to the performance parameters selected by the user.

[0056] Considering that the environment where the air conditioner is located is complex and changeable, and users have different requirements for the operating capacity of the air conditioner, the operating capacity of the air conditioner may not meet the needs of users in some cases. For example, when the room size and the operating capacity of the air conditioner are not well matched, or when the environment of the room where the air conditioner is located is poor (such as the top floor), or other situations. Based on this, the embodiment of the present invention proposes a method of upgrading the operating capacity of the air conditioner through OTA to change the operating capacity of the air conditioner, so that the air conditioner adapts to the user or environment, so that the adjustment effect of the air conditioner is better, and the user experience is better.

[0057] Optionally, in this embodiment, the air conditioner periodically or in real time obtains historical operating data within a period of time to analyze the operating capacity requirements of the user or the environment where the air conditioner is located for the air conditioner, and then determines whether to upgrade the operating capacity.

[0058] Optionally, the historical operation data includes but is not limited to operation mode M, outdoor temperature Tout, indoor temperature Tin, set temperature Tset, compressor operation frequency f, indoor fan speed S, operation power P, start time Tstart, shutdown time Tend, etc. The operation mode M includes but is not limited to: cooling, heating, automatic, air supply, dehumidification, etc.

[0059] Optionally, in this embodiment, historical operation data of the air conditioner for 6-8 months of the current year or the previous year may be obtained, and the user's demand for the air conditioner may be accurately judged through a large amount of data, thereby improving the accuracy of the judgment.

[0060] Optionally, the upgrade process of this embodiment can be triggered based on the cloud server or the outdoor unit. That is, the execution terminal can be the cloud server or the outdoor unit. When the execution terminal is the cloud server, the cloud server directly collects the historical operation data uploaded by each indoor unit or outdoor unit. When the execution terminal is the outdoor unit, the outdoor unit can obtain the historical operation data through the indoor unit or download it through the cloud server.

[0061] Step S20, determining whether the current operating capacity of the preset operating mode matches the required operating capacity based on the historical operating data;

[0062] By analyzing the historical operation data, the user's usage habits of the air conditioner can be determined. For cooling purposes, it is analyzed whether the user's usage habits of the air conditioner are too high or too low in cooling capacity, and then it is determined whether the cooling capacity matches the user's required operating capacity.

[0063] It should be noted that the correspondence between the operating mode and the performance parameters is configured when the air conditioner leaves the factory. Taking the cooling mode as an example, the operating capacity range of the cooling mode is A1~A2, and the corresponding performance parameter range is L1~L2. When the air conditioner is running, it can output the cooling capacity between A1~A2. Specifically, according to the user's set temperature, the target cooling capacity is determined, and then at least one set of performance parameters that can achieve the target cooling capacity is determined from L1~L2. The air conditioner is operated according to this set of performance parameters so that the air conditioner outputs the cooling capacity corresponding to the set temperature.

[0064] Under normal use, the air conditioner will operate in the middle range of the operating capacity range, that is, the air conditioner operates in a better working condition. When the operating capacity does not match the user's required operating capacity, the required capacity will be lower or higher during the actual operation of the air conditioner. Based on this, this embodiment determines whether the current operating capacity of the preset operating mode of the air conditioner matches the required operating capacity.

[0065] In an optional embodiment, the step of determining whether the current operating capacity of the preset operating mode matches the required operating capacity according to the historical operating data includes:

[0066] Determining, based on the historical operation data, a demand preference for a current operation capacity relative to the operation mode, the demand preference comprising at least one of increased capacity, decreased capacity, and moderate capacity;

[0067] When the demand preference is capacity increase or capacity reduction, it is determined that the current operating capacity does not match the required operating capacity.

[0068] The user's demand preference is determined by comparing the historical actual operating capacity determined by historical operating data with the reference operating capacity range of the air conditioner (such as the operating capacity range of the middle interval); or the user's demand preference is determined by comparing the historical actual operating capacity determined by historical operating data with the current operating capacity range of the air conditioner. Configuration demand preferences include capacity increase, capacity reduction and moderate capacity.

[0069] If the historical actual operating capacity is lower than the reference operating capacity range, the user demand preference is determined to be reduced capacity, that is, the current operating capacity is too large and needs to be reduced; if the historical actual operating capacity is higher than the reference operating capacity range, the user demand preference is determined to be increased capacity, that is, the current operating capacity is too small and needs to be increased. If the historical actual operating capacity is within the reference operating capacity range, the user demand preference is determined to be moderate capacity, that is, the current operating capacity is suitable for the current environment or the needs of the current user.

[0070] Optionally, in this embodiment, the user's demand preference is determined in the following ways, including but not limited to:

[0071] In one embodiment, the step of determining the demand preference relative to the current operating capacity of the operating mode based on the historical operating data includes:

[0072] Determine, based on the historical operating data within a preset time period, a first proportion by which the set parameter exceeds a reference set range;

[0073] When the first ratio is greater than or equal to a preset threshold, the demand preference is determined to be a capacity increase or a capacity decrease.

[0074] Optionally, the reference setting range is determined based on the refrigeration temperature corresponding to the current operating capacity of the air conditioner. Taking refrigeration as an example, when the lowest refrigeration temperature of the air conditioner's operating capacity is 10℃~15℃ and the highest refrigeration capacity is 28℃~32℃, the refrigeration temperature achieved by the operating capacity is between 10℃~32℃, and the reference setting range can be set to 20℃~28℃. When the user's historical operating data shows that the user often chooses a relatively low set temperature (such as close to the lower limit of the current operating capacity, below 20℃), it means that the refrigeration capacity corresponding to the current operating capacity is insufficient, and the user needs to lower the temperature to increase the refrigeration capacity, and the user's demand preference is determined to be increased capacity. Or if a relatively high set temperature is often selected (such as close to the upper limit of the current operating capacity, above 28℃), it means how high the refrigeration capacity corresponding to the current operating capacity is, and the user needs to increase the temperature to reduce the refrigeration capacity, and the user's demand preference is determined to be reduced capacity. It should be noted that the temperature range listed in this embodiment is only an example and is not specifically limited.

[0075] This embodiment determines a first ratio by setting the ratio of the number of settings that the parameter exceeds a reference setting range to the total number of settings. If the first ratio is greater than or equal to a preset threshold, it means that the user often selects a set temperature that is too low or too high. In this case, it means that the current operating capacity of the air conditioner is too small or too large, resulting in the temperature selected by the user being outside the reference setting range. In this case, the operating capacity of the air conditioner needs to be adjusted to prevent the cooling / heating capacity of the air conditioner from failing to meet user needs.

[0076] Optionally, the setting parameter exceeds the reference setting range includes the following situations: the setting parameter exceeds the upper limit value of the reference setting range, and the setting parameter exceeds the lower limit value of the reference setting range.

[0077] Therefore, the first ratio can be determined according to the ratio of the first number of times the setting parameter exceeds the upper limit of the reference setting range to the total setting number. In this case, if the first ratio is greater than or equal to the preset threshold, it is determined that the user's demand preference is capacity improvement. Optionally, the second ratio can also be determined according to the ratio of the second number of times the setting parameter exceeds the lower limit of the reference setting range to the total setting number. In this case, if the first ratio is greater than or equal to the preset threshold, it is determined that the user's demand preference is capacity reduction. Optionally, the second ratio can also be determined according to the ratio of the sum of the first number and the second number to the total setting number. In this case, the user's demand preference is determined in combination with the size of the first number and the second number. For example, if the difference between the first number and the second number is greater than the preset difference, the user's demand preference is determined to be capacity improvement. If the difference between the second number and the first number is greater than the preset difference, the user's demand preference is determined to be capacity reduction.

[0078] In this embodiment, the historical set temperature can directly reflect the user's use of the air conditioner, and can better reflect whether the operating capacity of the air conditioner matches the user's needs, thereby improving the accuracy of capacity upgrades.

[0079] As another embodiment, the step of determining the demand preference relative to the current operating capacity of the operating mode based on the historical operating data includes:

[0080] Determine, based on the historical operation data within a preset time period, a second ratio of the time period for the air conditioner to reach a temperature exceeding a reference time period for reaching a temperature;

[0081] When the second ratio is greater than or equal to a preset threshold, the demand preference is determined to be a capacity increase or a capacity decrease.

[0082] When the air conditioner is in a normal environment (not a harsh environment) or the operating capacity of the air conditioner matches the size of the room, the time it takes to reach temperature is within a fixed range. Therefore, each air conditioner has its corresponding reference range of time it takes to reach temperature.

[0083] Based on this, this embodiment uses the air conditioner's temperature reaching time in the air conditioner's historical operation data to determine whether the air conditioner is in a harsh environment or is working in a room where the room size and operating capacity do not match. If so, it means that the current operating capacity does not match the required capacity. This embodiment combines the historical temperature reaching time to determine the user's demand preference.

[0084] If the time to reach the temperature is greater than the upper limit of the reference time to reach the temperature range, it means that the air conditioner has a low operating capacity, resulting in slow temperature reaching. If the time to reach the temperature is less than the lower limit of the reference time to reach the temperature range, it means that the air conditioner has a strong operating capacity and reaches the temperature too quickly.

[0085] In this embodiment, based on historical operating data, the time it takes for the air conditioner to reach temperature each time it is turned on is determined, and the number of times the air conditioner is turned on with a time exceeding a reference time to reach temperature range is counted, and the ratio of the time to the total number of times the air conditioner is turned on is used to determine a second ratio. If the second ratio is greater than or equal to a preset threshold, it means that the operating capacity of the air conditioner is too high or too low relative to the current environment and does not match normal user needs. The operating capacity of the air conditioner needs to be adjusted to avoid the air conditioner's cooling / heating capacity being unable to meet user needs.

[0086] Optionally, the temperature reaching time length exceeding the reference temperature reaching time length range includes the following situations: the temperature reaching time length exceeds the upper limit of the reference temperature reaching time length range, or the temperature reaching time length exceeds the lower limit of the reference temperature reaching time length range. Therefore, the second ratio can be determined according to the ratio of the third number of times the temperature reaching time length exceeds the upper limit of the reference temperature reaching time length range and the total number of times the temperature reaching time length is reached. In this case, if the second ratio is greater than or equal to the preset threshold, the user's demand preference is determined to be improved. Optionally, the second ratio can also be determined according to the ratio of the fourth number of times the temperature reaching time length exceeds the lower limit of the reference time length range and the total number of times the temperature reaching time length is reached. In this case, if the second ratio is greater than or equal to the preset threshold, the user's demand preference is determined to be reduced in capacity. The second ratio can also be determined according to the ratio of the sum of the third number and the fourth number to the total number of times the temperature reaching time length is reached. In this case, the user's demand preference can be further determined in combination with the size of the third number and the fourth number. If the difference between the third number and the fourth number is greater than the preset difference, the user's demand preference is determined to be improved in capacity. If the difference between the third number and the fourth number is greater than the preset difference, the user's demand preference is determined to be reduced in capacity.

[0087] In this embodiment, the time it takes for the air conditioner to reach temperature is used to determine whether the current operating capacity of the air conditioner matches the environmental requirements, and then an OTA upgrade is performed to allow the air conditioner to adapt to the environment and adjust its capacity to avoid energy waste due to too fast cooling / heating, or too slow cooling / heating, which affects the user's comfort.

[0088] The following table lists a method for determining the operating capacity of the cooling mode and the heating mode:

[0089]

[0090] In another optional embodiment, the method of determining whether the current operating capacity of the preset operating mode matches the required operating capacity according to the historical operating data may also include:

[0091] It is also possible to determine whether the current operating capacity matches the required operating capacity based on the cooling / heating capacity of the air conditioner and the reference cooling / heating capacity.

[0092] Step S30, when the current operating capability of the preset operating mode does not match the required operating capability, upgrading the operating capability of the preset operating mode through OTA.

[0093] Optionally, the upgrade of the operating capability is performed within the hardware support range of the air conditioner. In this embodiment, the operating capability is upgraded by upgrading the performance parameters corresponding to the operating capability of the preset operating mode.

[0094] Optionally, the performance parameters include compressor operating frequency, opening of the electronic expansion valve, indoor fan speed or outdoor fan speed, etc.

[0095] The step of upgrading the performance parameters corresponding to the operating capability of the preset operating mode through OTA includes:

[0096] When the current operating capacity does not reach the required operating capacity, downloading a first performance parameter upgrade package to upgrade the performance parameter corresponding to the operating capacity of the preset operating mode so that the performance parameter increases;

[0097] When the required operating capacity is less than the current operating capacity, a second performance parameter upgrade package is downloaded to upgrade the performance parameters corresponding to the operating capacity of the preset operating mode, so that the performance parameters are reduced.

[0098] Optionally, the upgraded performance parameter includes an upgraded performance parameter range and / or a corresponding relationship between the performance parameter and the operating capability.

[0099] For example, in one embodiment, the performance parameter range corresponding to the current operating capacity is X1 to Y1. After the performance parameter of the operating capacity is upgraded, the corresponding performance parameter range is X2 to Y2, and the operating capacity range of the air conditioner is changed, and the user can use the air conditioner within the upgraded operating capacity range. The upgraded performance parameter range may be increased or partially repeated, for example, the upper limit value increases or decreases, and / or the lower limit value increases or decreases.

[0100] Alternatively, in another embodiment, the performance parameter range corresponding to the current operating capacity is X1-Y1, and when the set temperature is 26°C, the compressor operating frequency of the air conditioner is P1, the opening of the electronic expansion valve is B1, and the speed of the fan is R1. After the performance parameters of the upgraded operating capacity are upgraded, the corresponding performance parameter range is X2-Y2, and when the set temperature is 26°C, the compressor operating frequency of the air conditioner is P2, the opening of the electronic expansion valve is B2, and the speed of the fan is R2. In this way, when the upgraded air conditioner is also running at 26°C, based on the different corresponding operating capacities of the air conditioner, the cooling / heating amount is different, and the indoor regulation effect is different.

[0101] Optionally, in this embodiment, if the user's preference requirement is capability improvement, P2 is greater than P1, B2 is greater than B1, and / or R2 is greater than R1. If the user's preference requirement is capability reduction, P2 is less than P1, B2 is less than B1, and / or R2 is less than R1.

[0102] Optionally, the performance parameter upgrade package includes upgraded performance parameters and corresponding operating capabilities of the air conditioner. After downloading the performance parameter upgrade package, the performance parameters corresponding to the operating capabilities of the air conditioner are updated to achieve an upgrade of the operating capabilities.

[0103] Optionally, in some embodiments, each time the upgrade is performed, a fixed range may be set, such as increasing the opening of the electronic expansion valve by 10 steps each time, etc. By repeatedly executing this embodiment, multiple upgrades may be performed to meet user needs.

[0104] Alternatively, in other embodiments, the scope of each upgrade is determined based on the difference between the current operating capacity and the operating capacity required by the user, or the user's demand preferences are analyzed based on the user's historical operating data, and the correspondence between the user's demand preferences and the upgrade range is pre-set. During actual application, the corresponding upgrade range is determined based on the preference, so as to achieve a one-time upgrade to the operating capacity required by the user and reduce the number of upgrades.

[0105] Optionally, the air conditioner includes an indoor unit and an outdoor unit, and this embodiment can upgrade the operating capacity of the indoor unit or the outdoor unit.

[0106] In this embodiment, the historical operation data of the air conditioner is obtained, and then the user's required operation capacity is judged based on the historical operation data. If the current operation capacity does not match the required operation capacity, the current operation capacity of the preset operation mode is upgraded through OTA, and the operation capacity of the preset operation mode is upgraded. Based on OAT technology, combined with automatic identification of the matching of the current operation capacity and user needs, the air conditioner is automatically upgraded without the need for after-sales door-to-door processing, and the operation capacity of the air conditioner is upgraded in time, so that the air conditioner can adapt to different environments or users, improve the use effect of the air conditioner, and improve the user experience.

[0107] Second embodiment

[0108] Please refer to Figure 3 This embodiment is based on the above-mentioned first embodiment. This embodiment is applied in a central air conditioner, that is, the air conditioner includes multiple devices, including an outdoor unit and at least one indoor unit.

[0109] In a central air conditioner, the outdoor unit or multiple indoor units may all need to be upgraded. If multiple devices are upgraded at the same time, the upgrade will be slow. During the upgrade process, the device can only run in the air supply mode. In this way, in order to avoid multiple devices being upgraded at the same time and affecting the normal use of the air conditioner, this embodiment proposes the following steps:

[0110] Step S100, obtaining historical operation data of the air conditioner;

[0111] Step S200, determining whether the current operating capacity of the preset operating mode matches the required operating capacity based on the historical operating data;

[0112] Step S300, when it is determined that there are multiple devices to be upgraded whose current operating capacity of the preset operating mode does not match the required operating capacity, determine the upgrade order according to the devices to be upgraded;

[0113] Step S400: upgrading the operating capability of each device to be upgraded in sequence through OTA according to the upgrade sequence.

[0114] Optionally, in this embodiment, the historical operation data of the air conditioner is obtained, and for the historical operation data of different devices, the current operation capacity of the preset operation mode corresponding to the device is analyzed to see whether it matches the required operation capacity, and then the number of devices to be upgraded whose current operation capacity does not match the required operation capacity is determined. If there are multiple devices, it means that multiple devices need to be upgraded. In order to avoid upgrade congestion, an upgrade order is set for each device, and the operation capacity of each device to be upgraded is upgraded in turn according to the upgrade order.

[0115] Optionally, in this embodiment, the upgrade order of each device is determined based on the priority of the device. The priority of each device of the air conditioner is preset. After the device to be upgraded is determined, the upgrade order of each device to be upgraded is determined according to the preset priority. The device with a high priority is upgraded first, so that the device can upgrade its operating capacity as quickly as possible. Or the device with a high priority is upgraded later. The device with a high priority is the device with the highest current user demand. The user cannot use the device during the upgrade process. In order to influence the user's use of the device, it can be selected to upgrade the device with a relatively low use demand first, and then upgrade the device with a high use demand.

[0116] In this embodiment, the method for determining whether the current operating capability matches the required operating capability is the same as that of the first embodiment, and specific reference may be made to the first embodiment. The method for upgrading the operating capability of each device to be upgraded through OTA is also the same as that of the first embodiment, and specific reference may be made to the first embodiment, and will not be repeated here.

[0117] Optionally, in this embodiment, if there are multiple operation modes corresponding to the operation capabilities that need to be upgraded, the operation capabilities of each operation mode are upgraded in sequence according to the upgrade order of the operation modes. In summer, the cooling mode is upgraded before the heating mode, and in winter, the heating mode is upgraded before the cooling mode.

[0118] This embodiment upgrades the operating capacity of each device in a certain order to ensure the upgrade efficiency and avoid affecting the normal use of other devices during the upgrade process.

[0119] Third embodiment

[0120] Please refer to Figure 4 Based on all the above embodiments, this embodiment proposes that if the OTA upgrade fails during the OTA upgrade process, the upgrade is repeated to improve the success rate of the upgrade. After the step of upgrading the operating capability of the preset operating mode through OTA, it also includes:

[0121] Step S40, when OTA upgrade fails, start timing;

[0122] Step S50, when the timing duration reaches the preset duration, return to the step of performing the step of upgrading the operating capability of the preset operating mode through OTA.

[0123] Optionally, the preset time period may be 30 minutes or other time periods. After the preset time period, the OAT is requested to upgrade the operation capability of the preset operation mode again until the current OTA upgrade is successful.

[0124] Optionally, if there are multiple devices to be upgraded, according to the upgrade order, after the current device to be upgraded fails to upgrade, it will be upgraded again at a preset interval. After repeating the upgrade at least twice, if the upgrade still fails, the operating capacity of the next device to be upgraded will be upgraded. After the upgrade of other devices to be upgraded is completed, return to upgrade the previously unsuccessful upgraded devices.

[0125] Optionally, after the upgrade is completed, the operating capability version and corresponding performance parameters of each device before and after the upgrade are recorded.

[0126] During the OTA upgrade process, the upgrade may be interrupted due to various other factors. This embodiment automatically triggers repeated upgrades to improve the upgrade success rate.

[0127] The present invention also provides an air conditioner operating capacity upgrading device, which includes: a memory, a processor, and an operating capacity upgrading program stored in the memory and executable on the processor, wherein the operating capacity upgrading program implements the various steps of the air conditioner operating capacity upgrading method as described above when executed by the processor.

[0128] In addition, the present invention also provides a computer-readable storage medium, on which an operating capacity upgrade program is stored. When the operating capacity upgrade program is executed by a processor, the various steps of the air conditioner operating capacity upgrade method as described above are implemented.

[0129] Through the description of the above implementation methods, those skilled in the art can clearly understand that the above-mentioned embodiment methods can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk) as described above, and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, air conditioner, or network device, etc.) to execute the methods described in each embodiment of the present invention.

[0130] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
