[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on the Chinese patent application with application number 202311426534.6 and application date October 30, 2023, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into this application as a reference. Technical Field

[0003] The present application relates to the technical field of air conditioners, and in particular to an air conditioner and a control method, device and storage medium thereof. Background Art

[0004] In the air conditioning industry, pairing indoor and outdoor units is typically accomplished through preset parameters. For example, when pairing an outdoor unit with an indoor unit, factory experience and experimentation are used to determine the parameters required for pairing the outdoor unit with the indoor unit. These parameters are then written into the memory chips of both the outdoor and indoor units. These parameters are specific to each model, so when a specific outdoor unit model is paired with multiple indoor units, multiple sets of parameters are typically stored. The same principle applies to pairing an indoor unit with an outdoor unit, so this will not be discussed further.

[0005] In related technologies, only known internal or external unit parameters can be preset. When pairing with newly developed products, the stored parameters of the old product need to be updated to adapt to the new product. Updating the parameters requires disassembling the machine and rewriting the storage chip with a burner, or upgrading through remote control, wired control, OTA, etc.

[0006] However, any of the above methods requires the intervention of users or even professionals, so the adaptation efficiency is low.

[0046] The present application will be described in further detail below with reference to the accompanying drawings and embodiments.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0048] In order to clearly understand the technical solution of this application, the solution of the related technology is first introduced in detail.

[0049] In the related art, the external unit can only preset the control parameters of the known internal unit, and the internal unit can only preset the control parameters of the known external unit. Taking the external unit as an example, when pairing with a newly developed internal unit product, it is usually necessary to update the control parameters of the internal unit stored in the external unit to adapt to the new internal unit product. When updating the control parameters of the internal unit stored in the external unit, it is usually necessary to disassemble the unit, rewrite the storage chip with a burner, or upgrade through remote control, wired control, OTA, etc. The same applies to updating the stored control parameters of the external unit in the internal unit, so it will not be elaborated. However, any of the above methods requires the intervention of users or even professionals, so the adaptation efficiency is low.

[0050] When faced with the technical problems of related technologies, the inventors discovered through creative research that the indoor unit or outdoor unit can be set as the first device, and for any second device currently communicating with the first device, if the control parameters of the second device are not found in the local parameter library of the first device, a first parameter acquisition instruction is sent to the second device to obtain the first control parameters sent by the second device. The first control parameter is the parameter that the first device can use to control the operation of the second device. It can be seen that when the first device updates the control parameters of the second device, it can actively communicate to obtain them from the other party if the local parameter library does not store them. This is an adaptive adaptation method that does not require the intervention of users or even professionals in related technologies, so the adaptation efficiency is relatively high.

[0051] FIG1 is a control method for an air conditioner provided in one embodiment of the present application. The control method for an air conditioner provided in this embodiment may be executed by a first device of the air conditioner. The control method for an air conditioner provided in this embodiment includes the following steps:

[0052] Step 101: Obtain the model code of the second device.

[0053] The model code is the model code of the second device and is unique. Each second device has a unique corresponding model code.

[0054] A mapping relationship is pre-stored in the local parameter library of the first device. This mapping relationship stores the correspondence between the model code and control parameters of the legacy second device. Here, the legacy second device can be understood as a second device that has previously undergone parameter adaptation with the first device. The second device in step 101 is the second device currently in communication with the first device.

[0055] The triggering timing for the step of obtaining the model code of the second device may be any time point after starting the air conditioner and before the first device controls the operation of the second device. The first device actively obtains the model code of the second device, or the second device actively sends its own model code to the first device after powering on. The embodiments of the present application do not limit this.

[0056] Step 102: Search the local parameter library for the model code. If it is determined that the control parameter corresponding to the model code does not exist, send a first parameter acquisition instruction to the second device.

[0057] The control parameter is a parameter used by the first device to control the operation of the second device.

[0058] Specifically, after the model code of the second device is currently obtained, it can be searched in the local parameter library according to the model code of the second device and the aforementioned mapping relationship. If it is determined that the model code of the second device can be found in the local parameter library, it is determined that the control parameters corresponding to the model code exist; if it is determined that the model code of the second device cannot be found in the local parameter library, it is determined that the control parameters corresponding to the model code do not exist.

[0059] When it is determined that there are control parameters corresponding to the model code of the second device, the control parameters can be used directly for subsequent device control operations, or the availability of the control parameters can be judged again. If it is determined that the control parameters are unavailable, the latest control parameters can be obtained from the second device.

[0060] If it is determined that there is no control parameter corresponding to the model code of the second device, a first parameter acquisition instruction may be sent to the second device. In response to the first parameter acquisition instruction, the second device may send the first control parameter to the first device.

[0061] Step 103: Receive a first control parameter sent by the second device.

[0062] The first control parameter is a parameter used by the first device to control the operation of the second device.

[0063] For example, the first device is an indoor unit, and the first control parameter may be a frequency range of a compressor in the outdoor unit. Only after knowing the frequency range of the outdoor unit's compressor can the indoor unit operate the outdoor unit's compressor within the frequency range to ensure normal operation of the outdoor unit's compressor.

[0064] After receiving the first control parameter sent by the second device, the model code of the current second device and the first control parameter are stored in a mapping relationship in the local parameter library.

[0065] In this application, the model code of the second device is obtained; the model code is searched in the local parameter library, and if it is determined that the control parameter corresponding to the model code does not exist, a first parameter acquisition instruction is sent to the second device; the first control parameter sent by the second device is received; wherein, the first control parameter is the parameter used by the first device to control the operation of the second device; the first device is an indoor unit and the second device is an outdoor unit, or the first device is an outdoor unit and the second device is an indoor unit. It can be seen that when the first device updates the control parameters of the second device, it can actively communicate to obtain them from the other party if there is no local storage. This is an adaptive adaptation method that does not require the intervention of users or even professionals in related technologies, so the adaptation efficiency is relatively high.

[0066] Taking the first device as the indoor unit and the second device as the outdoor unit as an example, the process of the indoor unit obtaining the control parameters of the outdoor unit is: the indoor unit obtains the model code of the outdoor unit; searches for the model code of the outdoor unit in the local parameter library of the indoor unit. If it is determined that the control parameters corresponding to the model code do not exist, a first parameter acquisition instruction is sent to the outdoor unit; and the first control parameters sent by the outdoor unit are received.

[0067] When the first device is an outdoor unit and the second device is an indoor unit, the method for obtaining the first control parameter when the outdoor unit is the executing entity is the same as when the indoor unit is the executing entity. Specifically, the method involves: obtaining the model code of the first device; searching the local parameter library for the model code; if the control parameter corresponding to the model code does not exist, sending a third parameter acquisition instruction to the first device; and receiving the third control parameter sent by the first device. The third control parameter is the parameter used by the second device to control the operation of the first device. Here, the local parameter library refers to the parameter library of the second device.

[0068] In one embodiment, as shown in FIG2 , the control method of the air conditioner provided in this embodiment includes the following steps:

[0069] Step 101: Obtain the model code of the second device.

[0070] Step 102: Search the local parameter library for the model code. If it is determined that the control parameter corresponding to the model code does not exist, send a first parameter acquisition instruction to the second device.

[0071] Step 103: Receive a first control parameter sent by the second device.

[0072] Step 104: localize the first control parameter to obtain a localized first control parameter.

[0073] Among them, the purpose of parameter localization is to enable the first device to recognize and utilize the first control parameter after receiving it. Therefore, after the first control parameter is localized, the format of the localized first control parameter obtained can be recognized and read by the first device. The process of parameter localization depends on the storage format of the first control parameter. For example, for parameters that are directly arranged by address in binary format, they can be directly stored in the local adaptive parameter area after acquisition. This method has a fast access speed. For first control parameters stored in the form of key-value pairs, the first device updates the first control parameters in the form of each key-value pair to the local parameter library one by one. The present invention does not limit the storage method of the first control parameter. Some possible methods are listed here for the convenience of explanation.

[0074] In this embodiment, after receiving the first control parameter sent by the second device, the first control parameter is further localized to obtain a localized first control parameter; wherein the format of the localized first control parameter can be recognized and read by the first device. Because the first device performs parameter localization on the received first control parameter, the localized first control parameter obtained after the processing can be recognized and read by the first device, facilitating the first device to perform corresponding control based on the localized first control parameter.

[0075] In one embodiment, as shown in FIG3 , the control method of the air conditioner provided in this embodiment includes the following steps:

[0076] Step 101: Obtain the model code of the second device.

[0077] Step 102: Search the local parameter library for the model code. If it is determined that the control parameter corresponding to the model code does not exist, send a first parameter acquisition instruction to the second device.

[0078] Step 103: Receive a first control parameter sent by the second device.

[0079] Step 104: localize the first control parameter to obtain a localized first control parameter.

[0080] Step 105: Obtain a first operation instruction.

[0081] The purpose of the first device actively communicating to obtain the first control parameter is to subsequently control the operation of the second device accordingly based on the first control parameter. The control operation starts when the first device receives a first operation instruction. The first operation instruction can be generated by a user pressing a button on a remote control, or sent by a user terminal to the air conditioner via Bluetooth, near-field communication, or other means. This embodiment of the application does not specifically limit this.

[0082] The first operation instruction is generated after the air conditioner is started, which is the triggering time point for the first device to control the operation of the second device.

[0083] Step 106 : In response to the first operating instruction, control the second device to operate according to the localized first control parameter, so that the second device performs heat exchange with an outdoor or indoor space through a refrigerant.

[0084] Specifically, the first device controls the operation of the second device according to the localized first control parameter in response to the first operation instruction. The operation of the second device means that the second device exchanges heat with the indoor or outdoor space through the refrigerant. As mentioned above, if the first device is an outdoor unit, the operation of the second device means that the second device exchanges heat with the indoor space through the refrigerant. If the first device is an indoor unit, the operation of the second device means that the second device exchanges heat with the outdoor space through the refrigerant. Heat exchange refers to the transfer of heat from one object to another. For example, if the second device exchanges heat with the outdoor space through the refrigerant, it means that the second device transfers heat from the outdoor space to the indoor space through the refrigerant.

[0085] Taking the operating frequency of the compressor of the outdoor unit controlled by the indoor unit as an example, the first device is the indoor unit, the second device is the outdoor unit, the localized first control parameter is 1~70Hz, and the first device responds to the first operating instruction to control the compressor of the second device to operate in the frequency range of 1~70Hz.

[0086] In this embodiment, a first operating instruction is obtained; in response to the first operating instruction, the second device is controlled to operate according to the localized first control parameters, so that the second device exchanges heat with the outdoor or indoor space via the refrigerant. During application, after receiving the first operating instruction, the first device controls the second device to operate according to the localized first control parameters, thereby enabling normal operation of the second device to perform heat exchange.

[0087] In one embodiment, as shown in FIG3 , the control method of the air conditioner provided in this embodiment includes the following steps:

[0088] a. Get the first running instruction.

[0089] b. Obtain the model code of the second device.

[0090] c. Searching for the model code in a local parameter library, and if it is determined that the control parameter corresponding to the model code does not exist, sending a first parameter acquisition instruction to the second device.

[0091] d. Receive the first control parameter sent by the second device.

[0092] e. If it is determined that the first control parameter is received, in response to the first operation instruction, control the operation of the second device according to the localized first control parameter, so that the second device exchanges heat with the outdoor or indoor space through the refrigerant.

[0093] This embodiment differs from the previous embodiment in that the model code of the second device can be obtained after receiving the first operation instruction and before responding to the first operation instruction by first receiving the first control parameter.

[0094] In one embodiment, if it is determined that the control parameter corresponding to the model code exists, the method further includes the following steps:

[0095] a. Send a second parameter acquisition instruction to the second device.

[0096] When it is determined that the control parameters corresponding to the model code of the second device exist in the local parameter library of the first device, the first device can send a second parameter acquisition instruction to the second device, and the second device sends the second control parameters to the first device in response to the second parameter acquisition instruction.

[0097] b. Receive a second control parameter sent by the second device.

[0098] The second control parameter is the latest control parameter after the second device is updated. If the second device is updated, the second control parameter is different from the corresponding control parameter stored in the local parameter library of the first device. If the second device is not updated, the second control parameter is the same as the corresponding control parameter stored in the local parameter library of the first device.

[0099] In one embodiment, upon determining that the control parameters corresponding to the model code exist in the local parameter library, the first device may send a second parameter acquisition instruction to the second device, regardless of whether the second device has been updated, to obtain the latest control parameters in the second device, i.e., the second control parameters. In one embodiment, the first device may also first determine whether the second device has been updated, and upon determining that the second device has been updated, send a second parameter acquisition instruction to the second device to obtain the latest control parameters in the second device.

[0100] In this embodiment, a second parameter acquisition instruction is sent to the second device, and a second control parameter is received from the second device. The second control parameter is the latest control parameter after the second device is updated. By sending the second parameter acquisition instruction to the second device, the latest control parameter can be obtained from the second device. The first device can then ensure normal control of the second device based on the latest control parameter.

[0101] In one embodiment, if it is determined that a control parameter corresponding to the model code exists, the method further includes:

[0102] a. Send an information acquisition instruction to the second device.

[0103] b. Receive the first file verification code sent by the second device.

[0104] The first file verification code is the file verification code of the latest control parameter of the second device. The file verification code is unique. Each control parameter carries a unique file verification code. If the control parameter is modified, the file verification code will change accordingly.

[0105] c. If it is determined that the first file verification code and the second file verification code are different, it is determined that the second device has been updated, and a second parameter acquisition instruction is sent to the second device.

[0106] The second file verification code is a file verification code of the control parameters of the second device stored in the local parameter library of the first device.

[0107] If the first file verification code differs from the second file verification code, it indicates that the second device has been updated and the control parameters for the second device stored in the first device's local parameter library have become invalid. If the control parameters have become invalid, the first device will initiate a request to the second device to obtain the latest control parameters. If the control parameters have not become invalid, the first device will not initiate a request to the second device and will control the second device based on the stored control parameters.

[0108] d. Receive a second control parameter sent by the second device.

[0109] The second control parameter is the latest control parameter after the second device is updated.

[0110] In this embodiment, an information acquisition instruction is sent to the second device; a first file verification code is received from the second device; wherein the first file verification code is the file verification code of the latest control parameters of the second device; if it is determined that the first file verification code and the second file verification code are different, it is determined that the second device has been updated, and the step of sending a second parameter acquisition instruction to the second device is executed; wherein the second file verification code is the file verification code of the control parameters of the second device stored in the local parameter library. By verifying the first file verification code and the second file verification code, it can be determined whether the second device has been updated. If an update has occurred, an instruction is sent to the second device to obtain the latest control parameters of the second device. Compared with the method of obtaining the latest control parameters of the second device regardless of whether the second device has been updated, this embodiment can reduce data redundancy of the control parameters.

[0111] In one embodiment, after receiving the second control parameter sent by the second device, the method further includes:

[0112] a. Get the second operation instruction.

[0113] There is no essential difference between the second operating instruction and the first operating instruction, and the names are different only for the convenience of distinction.

[0114] b. In response to the second operation instruction, controlling the operation of the second device according to the second control parameter, so that the second device exchanges heat with an outdoor or indoor space through a refrigerant.

[0115] In this embodiment, after receiving the second control parameter, the first device obtains the second operation instruction and can control the operation of the second device according to the second control parameter.

[0116] In one embodiment, after receiving the second control parameter sent by the second device, the method further includes:

[0117] a. Perform parameter localization on the second control parameter to obtain a localized second control parameter.

[0118] The format of the localized second control parameter can be recognized and read by the first device.

[0119] b. Obtain the second operation instruction.

[0120] The second operation instruction may be generated by a user's remote control button operation, or sent by the user terminal to the air conditioner via Bluetooth, near field communication, etc., without specific limitation.

[0121] The second operation instruction is generated after the air conditioner is started, which is the triggering time point for the first device to control the operation of the second device.

[0122] c. In response to the second operation instruction, controlling the operation of the second device according to the localized second control parameter, so that the second device exchanges heat with an outdoor or indoor space through a refrigerant.

[0123] Here, the operation of the second device is controlled according to the localized second control parameters. For the process method, reference may be made to the relevant limitations according to the localized first control parameters.

[0124] In this embodiment, during the application process, after receiving the second operation instruction, the first device controls the operation of the second device according to the localized second control parameters, so that the second device can be normally controlled to perform hot exchange.

[0125] In one embodiment, the air conditioner control method provided in this embodiment includes the following steps:

[0126] a. Obtain the model code of the second device.

[0127] b. Searching for the model code in a local parameter library, and if it is determined that the control parameter corresponding to the model code exists, sending an information acquisition instruction to the second device.

[0128] c. Receive the first file verification code sent by the second device.

[0129] The first file verification code is the file verification code of the latest control parameter of the second device

[0130] d. If it is determined that the first file verification code and the second file verification code are different, it is determined that the second device has been updated, and a second parameter acquisition instruction is sent to the second device.

[0131] The second file verification code is a file verification code of the control parameters of the second device stored in the local parameter library.

[0132] e. Receive a second control parameter sent by the second device.

[0133] The second control parameter is the latest control parameter of the second device after being updated.

[0134] f. Perform parameter localization on the second control parameter to obtain a localized second control parameter.

[0135] g. Get the second operation instruction.

[0136] h. In response to the second operating instruction, control the operation of the second device according to the localized second control parameter, so that the second device exchanges heat with an outdoor or indoor space through a refrigerant.

[0137] In this embodiment, the process of first obtaining the model code of the second device and then obtaining the localized second control parameters is performed. When the localized second control parameters are generated, when the first operating instruction is subsequently obtained, the operation of the second device is controlled according to the localized second control parameters in response to the first operating instruction.

[0138] In one embodiment, the air conditioner control method provided in this embodiment includes the following steps:

[0139] a. Get the second operation instruction.

[0140] b. Obtain the model code of the second device.

[0141] c. Searching for the model code in a local parameter library, and if it is determined that the control parameter corresponding to the model code exists, sending an information acquisition instruction to the second device.

[0142] d. Receive the first file verification code sent by the second device.

[0143] The first file verification code is the file verification code of the latest control parameter of the second device

[0144] e. If it is determined that the first file verification code and the second file verification code are different, it is determined that the second device has been updated, and a second parameter acquisition instruction is sent to the second device.

[0145] The second file verification code is a file verification code of the control parameters of the second device stored in the local parameter library.

[0146] f. Receive a second control parameter sent by the second device.

[0147] The second control parameter is the latest control parameter of the second device after being updated.

[0148] g. Perform parameter localization on the second control parameter to obtain a localized second control parameter.

[0149] h. In response to the second operating instruction, control the operation of the second device according to the localized second control parameter, so that the second device exchanges heat with an outdoor or indoor space through a refrigerant.

[0150] In this embodiment, the second operating instruction is first obtained, and then the model code of the second device is obtained to obtain the localized second control parameters. Only when the localized second control parameters are generated, the second operating instruction is responded to and the operation of the second device is controlled according to the localized second control parameters.

[0151] In one embodiment, the air conditioner control method further includes: updating the control parameters of the second device and the second file verification code in the local parameter library based on the second control parameters.

[0152] That is, when the latest control parameters are obtained, the first device updates the data in the local parameter library. In addition, the corresponding control parameters previously stored in the local parameter library can be deleted to reduce data redundancy.

[0153] In this embodiment, by updating the control parameters of the second device and the second file verification code in the local parameter library based on the second control parameter, the first device does not need to obtain them from the second device each time it is used subsequently.

[0154] In each of the above embodiments, as shown in FIG4 , the storage area of ​​the first device may include: a local parameter library, a first adaptive parameter library, and a second adaptive parameter library. The local parameter library, the first adaptive parameter library, and the second adaptive parameter library are communicatively connected to the processor of the first device. The local parameter library stores a mapping relationship that stores a preset model code of the second device and the corresponding control parameters. The first adaptive parameter library stores control parameters obtained from the second device via communication, such as the first control parameter and the second control parameter. The second adaptive parameter library stores control parameters for the other party to obtain from the first device via communication, such as the aforementioned third control parameter.

[0155] The methods described in the above embodiments are for a one-to-one air conditioner setup, but can also be applied to a one-to-multiple setup. In this scenario, the outdoor unit, acting as the network master, polls all connected indoor units on the network to obtain corresponding control parameters from each unit. The control parameters from the outdoor unit can be sent to each indoor unit using a broadcast notification.

[0156] The present application will be described in further detail below in conjunction with application examples.

[0157] In a specific embodiment, as shown in FIG5 , the control method of the air conditioner specifically includes:

[0158] When the second device is connected to the first device, step 201 is executed to obtain the model code of the second device. After the first device obtains the model code of the second device, step 202 is first executed to search the local parameter library for the model code. If the model code is determined to exist, it is determined that the second device is not connected for the first time. If the model code is determined not to exist, it is determined that the second device is connected for the first time. Accordingly, the second device connected for the first time does not have corresponding control parameters in the local parameter library of the first device.

[0159] For a second device connected for the first time, the local parameter library of the first device does not contain control parameters corresponding to its model code. In this case, step 203 is executed, and the first device sends a first parameter acquisition instruction to the second device. In response to the first parameter acquisition instruction, the second device sends a first control parameter to the first device. The first device then executes step 204 to receive the first control parameter sent by the second device. The first control parameter is the parameter used by the first device to control the operation of the second device.

[0160] For a second device that is not connected for the first time, the first device can directly use the control parameters of the second device stored in the local parameter library as the parameters for controlling the operation of the second device. Furthermore, consider that the control parameters of the second device may have been updated, and the control parameters of the second device stored in the local parameter library of the first device have not been synchronized and updated in a timely manner. In this case, after executing step 202 to determine that the control parameters corresponding to the model code exist in the local parameter library, the first device can also execute step 205 to determine whether the second device has been updated. If it is determined that the second device has been updated, the first device executes step 206 to send a second parameter acquisition instruction to the second device. The second device sends the second control parameters to the first device in response to the second parameter acquisition instruction. The first device then executes step 207 to receive the second control parameters sent by the second device. The second control parameters are the latest control parameters in the second device used by the first device to control the operation of the second device. After receiving the second control parameters, if the first device obtains the second operation instruction, it will respond to the second operation instruction and control the operation of the second device according to the second control parameters, so that the second device exchanges heat with the outdoor or indoor space through the refrigerant.

[0161] It should be noted that when the first device is an indoor unit, the second device is an outdoor unit. When the first device is an outdoor unit, the second device is an indoor unit. Furthermore, the first device and the second device are located in the same air conditioner.

[0162] It is understandable that the second device can also obtain the model code of the first device and execute a method similar to that of the first device, thereby updating the control parameters of the first device on the second device side, thereby achieving adaptive adaptation control.

[0163] In this application embodiment, when the first device updates the control parameters of the second device, it can actively communicate to obtain them from the other party if they are not stored in the local parameter library. This is an adaptive adaptation method that does not require the intervention of users or even professionals in related technologies. Therefore, the adaptation efficiency is relatively high.
