[0002] In the field of air conditioners, the combination of indoor and outdoor units is generally achieved through preset parameters. Taking the combination of outdoor units with indoor units as an example, before leaving the factory, experience and experiments are used to determine what parameters are required when the outdoor unit is matched with the indoor unit, and the parameters are written into the storage chips of the outdoor unit and the indoor unit respectively. These parameters are only valid for specific indoor and outdoor unit models, so when a specific model of outdoor unit needs to be matched with multiple models of indoor units, it is usually necessary to store multiple sets of parameters. The same applies to the combination of indoor units with outdoor units, so I will not go into details.

[0003] In the related technology, only known internal or external parameters can be preset.

[0043] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0044] 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 belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0045] In order to clearly understand the technical solution of the present application, the solution of the related technology is first introduced in detail.

[0046] 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 matching 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 machine and then rewrite the storage chip with a burner, or upgrade it through remote control, wire control, OTA, etc. The same is true for the internal unit when updating the stored control parameters of the external 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.

[0047] When faced with technical problems of related technologies, the inventor discovered through creative research that the indoor unit or the 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 parameter sent by the second device. The first control parameter is a 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.

[0048] Figure 1 A control method for an air conditioner provided in an embodiment of the present application is provided. The execution subject of the control method for an air conditioner provided in this embodiment may be a first device of the air conditioner. The control method for an air conditioner provided in this embodiment includes the following steps:

[0049] Step 101, obtaining the model code of the second device.

[0050] The model code is the model code of the second device and is unique. Each second device has a unique corresponding model code.

[0051] A mapping relationship is pre-stored in the local parameter library of the first device, and the mapping relationship stores the correspondence between the model code and the control parameter of the old second device. Here, the old second device can be understood as a second device that has been parameter-adapted with the first device. The second device in step 101 is the second device that is currently communicating with the first device.

[0052] 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 power-on. The embodiments of the present application do not limit this.

[0053] Step 102: Search the local parameter library for the model code. If it is determined that there is no control parameter corresponding to the model code, send a first parameter acquisition instruction to the second device.

[0054] The control parameter is a parameter used by the first device to control the operation of the second device.

[0055] 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 there are control parameters corresponding to the model code; if it is determined that the model code of the second device cannot be found in the local parameter library, it is determined that there are no control parameters corresponding to the model code.

[0056] 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.

[0057] When 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, and the second device may send a first control parameter to the first device in response to the first parameter acquisition instruction.

[0058] Step 103: Receive a first control parameter sent by the second device.

[0059] The first control parameter is a parameter used by the first device to control the operation of the second device.

[0060] Exemplarily, the first device is an indoor unit, and the first control parameter may be a frequency range of a compressor in an outdoor unit. Only after the indoor unit knows the frequency range of the compressor in the outdoor unit, can the compressor of the outdoor unit operate within the above frequency range to ensure the normal operation of the compressor in the outdoor unit.

[0061] 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 a local parameter library.

[0062] In the present 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 there is no control parameter corresponding to the model code, 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 a parameter for 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 from the other party when 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.

[0063] 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, and if it is determined that there is no control parameter corresponding to the model code, sends a first parameter acquisition instruction to the outdoor unit; and receives the first control parameter sent by the outdoor unit.

[0064] When the first device is an outdoor unit, the second device is an indoor unit. When the outdoor unit is used as the execution subject, the method flow for obtaining the first control parameter is the same as that when the indoor unit is used as the execution subject, specifically: obtaining the model code of the first device; searching the model code in the local parameter library, and if it is determined that there is no control parameter corresponding to the model code, sending a third parameter acquisition instruction to the first device; receiving the third control parameter sent by the first device; wherein 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.

[0065] In one embodiment, if Figure 2 As shown, the control method of the air conditioner provided in this embodiment includes the following steps:

[0066] Step 101, obtaining the model code of the second device.

[0067] Step 102: Search the local parameter library for the model code. If it is determined that there is no control parameter corresponding to the model code, send a first parameter acquisition instruction to the second device.

[0068] Step 103: Receive a first control parameter sent by the second device.

[0069] Step 104: localize the first control parameter to obtain a localized first control parameter.

[0070] 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 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 the first control parameter 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.

[0071] 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. Since the first device performs parameter localization processing on the received first control parameter, the localized first control parameter obtained after the processing can be recognized and read by the first device, so that the first device can control it accordingly according to the localized first control parameter.

[0072] In one embodiment, if Figure 3 As shown, the control method of the air conditioner provided in this embodiment includes the following steps:

[0073] Step 101, obtaining the model code of the second device.

[0074] Step 102: Search the local parameter library for the model code. If it is determined that there is no control parameter corresponding to the model code, send a first parameter acquisition instruction to the second device.

[0075] Step 103: Receive a first control parameter sent by the second device.

[0076] Step 104: localize the first control parameter to obtain a localized first control parameter.

[0077] Step 105: Obtain a first operation instruction.

[0078] 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 according to the first control parameter. The starting point of the control operation is that the first device receives the first operation instruction, which can be generated by the user's remote control button operation, and the user terminal sends it to the air conditioner through Bluetooth, near field communication, etc., which is not specifically limited in the embodiments of the present application.

[0079] 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.

[0080] Step 106: 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 an outdoor or indoor space through a refrigerant.

[0081] 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. Exemplarily, if the second device exchanges heat with the outdoor space through the refrigerant, it means that the second device transfers the heat of the outdoor space to the indoor space through the refrigerant.

[0082] Taking the operating frequency of the compressor of the indoor unit controlling the outdoor 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.

[0083] In this embodiment, a first operation instruction is obtained; in response to the first operation instruction, the second device is controlled to operate according to the localized first control parameter, so that the second device performs heat exchange with the outdoor or indoor space through the refrigerant. In the application process, after receiving the first operation instruction, the first device controls the second device to operate according to the localized first control parameter, so that the second device can be normally controlled to perform heat exchange.

[0084] In one embodiment, if Figure 3 As shown, the control method of the air conditioner provided in this embodiment includes the following steps:

[0085] a. Get the first running instruction.

[0086] b. Obtain the model code of the second device.

[0087] c. Searching for the model code in the local parameter library, and if it is determined that there is no control parameter corresponding to the model code, sending a first parameter acquisition instruction to the second device.

[0088] d. Receive the first control parameter sent by the second device.

[0089] e. If it is determined that the first control parameter is received, in response to the first operation instruction, the second device is controlled to operate according to the localized first control parameter, so that the second device exchanges heat with an outdoor or indoor space through a refrigerant.

[0090] The present embodiment is different 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.

[0091] In one embodiment, if it is determined that there is a control parameter corresponding to the model code, the method further includes the following steps:

[0092] a. Send a second parameter acquisition instruction to the second device.

[0093] 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 parameter to the first device in response to the second parameter acquisition instruction.

[0094] b. Receive a second control parameter sent by the second device.

[0095] 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.

[0096] In one embodiment, the first device may, when determining that the control parameters corresponding to the model code exist in the local parameter library, send a second parameter acquisition instruction to the second device, regardless of whether the second device is 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 is updated, and when determining that the second device is updated, send a second parameter acquisition instruction to the second device to obtain the latest control parameters in the second device.

[0097] In this embodiment, a second parameter acquisition instruction is sent to the second device; and a second control parameter sent by the second device is received; wherein 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, and the first device can ensure normal control of the operation of the second device according to the latest control parameter.

[0098] In one embodiment, if it is determined that there is a control parameter corresponding to the model code, the method further includes:

[0099] a. Send an information acquisition instruction to the second device.

[0100] b. Receive the first file verification code sent by the second device.

[0101] 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, and each control parameter carries a unique file verification code. If the control parameter is modified, the file verification code changes accordingly.

[0102] c. If it is determined that the first file verification code is different from the second file verification code, it is determined that the second device is updated, and a second parameter acquisition instruction is sent to the second device.

[0103] 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.

[0104] The first file verification code is different from the second file verification code, indicating that the second device is updated and the control parameters of the second device stored in the local parameter library of the first device are invalid. In the case of invalid control parameters, the first device initiates a request to the second device to obtain the latest control parameters. In the case of valid control parameters, the first device will not initiate a request to the second device, and the first device can control the second device according to the stored control parameters.

[0105] d. Receive a second control parameter sent by the second device.

[0106] The second control parameter is the latest control parameter after the second device is updated.

[0107] In this embodiment, an information acquisition instruction is sent to the second device; a first file verification code sent by the second device is received; wherein the first file verification code is a 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 a 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. In the case of an update, 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.

[0108] In one embodiment, after receiving the second control parameter sent by the second device, the method further includes:

[0109] a. Get the second operation instruction.

[0110] There is no essential difference between the second operation instruction and the first operation instruction, and the names are different only for the convenience of distinction.

[0111] 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.

[0112] 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.

[0113] In one embodiment, after receiving the second control parameter sent by the second device, the method further includes:

[0114] a. Perform parameter localization on the second control parameter to obtain a localized second control parameter.

[0115] The format of the localized second control parameter can be recognized and read by the first device.

[0116] b. Get the second operation instruction.

[0117] The second operation instruction may be generated by a user's remote control button operation, or sent by a user terminal to the air conditioner via Bluetooth, near field communication, etc., without specific limitation.

[0118] 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.

[0119] c. In response to the second operation instruction, the second device is controlled to operate according to the localized second control parameter, so that the second device exchanges heat with an outdoor or indoor space through a refrigerant.

[0120] Here, the operation of the second device is controlled according to the localized second control parameters, and the process method can refer to the relevant limitations according to the localized first control parameters.

[0121] 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.

[0122] In one embodiment, the control method of the air conditioner provided in this embodiment includes the following steps:

[0123] a. Obtain the model code of the second device.

[0124] b. Searching for the model code in the local parameter library, and if it is determined that there is a control parameter corresponding to the model code, sending an information acquisition instruction to the second device.

[0125] c. Receive the first file verification code sent by the second device.

[0126] The first file verification code is the file verification code of the latest control parameter of the second device.

[0127] d. If it is determined that the first file verification code is different from the second file verification code, it is determined that the second device is updated, and a second parameter acquisition instruction is sent to the second device.

[0128] The second file verification code is a file verification code of the control parameters of the second device stored in the local parameter library.

[0129] e. Receive a second control parameter sent by the second device.

[0130] The second control parameter is the latest control parameter after the second device is updated.

[0131] f. Perform parameter localization on the second control parameter to obtain a localized second control parameter.

[0132] g. Get the second operation instruction.

[0133] h. In response to the second operation 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.

[0134] In this embodiment, the process of first obtaining the model code of the second device and then obtaining the localized second control parameters is carried out. 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.

[0135] In one embodiment, the control method of the air conditioner provided in this embodiment includes the following steps:

[0136] a. Get the second operation instruction.

[0137] b. Obtain the model code of the second device.

[0138] c. Searching for the model code in the local parameter library, and if it is determined that there is a control parameter corresponding to the model code, sending an information acquisition instruction to the second device.

[0139] d. Receive the first file verification code sent by the second device.

[0140] The first file verification code is the file verification code of the latest control parameter of the second device.

[0141] e. If it is determined that the first file verification code is different from the second file verification code, it is determined that the second device is updated, and a second parameter acquisition instruction is sent to the second device.

[0142] The second file verification code is a file verification code of the control parameters of the second device stored in the local parameter library.

[0143] f. Receive a second control parameter sent by the second device.

[0144] The second control parameter is the latest control parameter after the second device is updated.

[0145] g. Perform parameter localization on the second control parameter to obtain a localized second control parameter.

[0146] h. In response to the second operation 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.

[0147] 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.

[0148] 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 parameter.

[0149] 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.

[0150] 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.

[0151] In the above embodiments, Figure 4As shown, the storage area of ​​the first device may include: a local parameter library, a first adaptive parameter library, and a second adaptive parameter library, and the local parameter library, the first adaptive parameter library, and the second adaptive parameter library are communicatively connected with the processor of the first device. Among them, a mapping relationship is stored in the local parameter library, and the mapping relationship stores a preset model code of the second device and a corresponding control parameter. The first adaptive parameter library stores control parameters obtained from the second device through 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 through communication, such as the aforementioned third control parameter.

[0152] The methods described in the above embodiments are described for one-to-one air conditioners, but can also be used in one-to-many air conditioners. In the one-to-many usage scenario, the outdoor unit as the network host polls all indoor units in the network that are connected to it for communication, and obtains corresponding control parameters from each indoor unit. The control parameters of the outdoor unit can be sent to each indoor unit using a broadcast notification method.

[0153] The present application is further described in detail below in conjunction with application examples.

[0154] In a specific embodiment, Figure 5 As shown, the control method of the air conditioner specifically includes:

[0155] 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 whether the model code exists in the local parameter library. If it is determined that the model code exists, it is determined that the second device is not connected for the first time. If it is determined that the model code does not exist, it is determined that the second device is connected for the first time. Accordingly, the second device that is connected for the first time does not have corresponding control parameters in the local parameter library of the first device.

[0156] For the second device connected for the first time, there is no control parameter corresponding to its model code in the local parameter library of the first device. In this case, step 203 is executed, the first device sends a first parameter acquisition instruction to the second device, the second device responds to the first parameter acquisition instruction and sends a first control parameter to the first device, and the first device executes step 204 to receive the first control parameter sent by the second device. The first control parameter is a parameter used by the first device to control the operation of the second device.

[0157] For the 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. Further, it is considered that the control parameters of the second device may be 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 time. In this case, the first device can also perform step 205 to determine whether the second device has been updated after performing step 202 to determine that there are control parameters corresponding to the model code in the local parameter library, and in the case of determining that the second device has been updated, perform step 206 to send a second parameter acquisition instruction to the second device, and the second device sends the second control parameter to the first device in response to the second parameter acquisition instruction. The first device performs step 207 to receive the second control parameter sent by the second device. The second control parameter is the latest control parameter in the second device for the first device to control the operation of the second device. After the first device receives the second control parameter, if the second operation instruction is obtained, it responds to the second operation instruction and controls the operation of the second device according to the second control parameter, so that the second device exchanges heat with the outdoor or indoor space through the refrigerant.

[0158] It should be noted here 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. Moreover, the first device and the second device are located in the same air conditioner.

[0159] 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.

[0160] In this application embodiment, when the first device updates the control parameters of the second device, it can actively communicate to obtain from the other party if the parameters 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, so the adaptation efficiency is relatively high.
