[0082] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be described in further detail below with reference to the accompanying drawings, and the described embodiments should not be regarded as limiting the present application, and all other embodiments obtained by those of ordinary skill in the art without making any creative efforts fall within the scope of protection of the present application.

[0083] In the following description, "some embodiments" are referred to, which describe a subset of all possible embodiments, but it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0084] In the following description, the terms "first\second\third" are only to distinguish similar objects, and do not represent a specific order of the objects, and it can be understood that "first\second\third" can be interchanged in a specific order or sequence as allowed, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0085] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.

[0086] A conventional household air conditioner includes an indoor unit and an outdoor unit. When controlling the air conditioner, the indoor unit serves as a master control device and undertakes the main control of the indoor unit and the outdoor unit. The indoor unit calculates air conditioner operating parameters by monitoring various operating state parameters in real time, generates control instructions, and sends the control instructions to the outdoor unit through indoor-outdoor communication lines connected by the indoor unit to adjust the operating parameters of the outdoor unit, including the frequency of the compressor and the rotation speed of the outdoor fan.

[0087] That is, in the control, the traditional household air conditioner takes the indoor unit as the center control point to control the whole air conditioning system, which is too dependent on the indoor unit and makes high reliability requirements for the indoor-outdoor communication line and power supply line. However, in the production, transportation, installation, operation and other scenes, there is a risk of product failure, which can easily cause the outdoor unit and the indoor unit to fail to communicate, or the indoor unit to fail to control the outdoor unit to run. Once the center control point where the indoor unit is located cannot issue control instructions to the outdoor unit, the power supply to the outdoor unit will be cut off for safety considerations, so that the outdoor unit cannot operate normally, and the air conditioner cannot provide normal cooling / heating function, resulting in high air conditioner failure rate and unreliable air conditioner operation.

[0088] Based on this, the embodiment of the present application provides a control method of an air conditioning system, applied to an indoor unit, as shown in Figure 1 The air conditioning system 1 comprises:

[0089] Step 101, determine that the indoor unit meets the condition of entering a preset control mode, and control the indoor unit to enter the preset control mode.

[0090] In the preset control mode, the outdoor unit controls the outdoor unit to run based on a self-learning algorithm, and the preset control mode can also be referred to as an outdoor unit self-learning control mode.

[0091] It should be understood that the execution subject of the embodiment is the indoor unit of the above-mentioned air conditioning system, and the indoor unit of the air conditioning system has functions of data processing, data communication and program running. Generally, the operation of each component in the indoor unit of the air conditioning system can be driven by a core controller, so the execution subject of the embodiment can also be the core controller of the above-mentioned indoor unit, and the core controller can be a processor.

[0092] It should be noted that the preset control mode is a mode in which the state of the indoor unit of the air conditioning system is a fault state. Understandably, during the operation of the air conditioning system, if the indoor unit meets the condition of entering the preset control mode, it indicates that the state of the indoor unit of the air conditioning system is a fault state, the indoor unit and the outdoor unit cannot communicate normally, and the indoor unit cannot issue communication information to the outdoor unit through the communication line. Therefore, the indoor unit is controlled to enter the preset control mode, that is, the indoor unit enters the outdoor unit self-learning control mode. In the preset control mode, even if the indoor unit and the outdoor unit cannot communicate normally, the outdoor unit can still control the outdoor unit to run automatically based on the self-learning algorithm. The communication information includes operation parameter information, control instruction information, operation mode information, etc.

[0093] It should be noted that a default control mode can be set, and the default control mode is a mode in which the state of the indoor unit of the air conditioning system is a normal state. Understandably, in the default control mode, the indoor unit and the outdoor unit can normally communicate, and the indoor unit can issue communication information to the outdoor unit through the communication line to control the outdoor unit to perform corresponding actions according to the received communication information.

[0094] It should be noted that the self-learning algorithm is an artificial intelligence (AI) based machine learning algorithm, including but not limited to a random forest algorithm, a decision tree based integrated machine learning algorithm, a deep learning algorithm, etc. The specific setting can be made according to actual needs, and the present application does not make specific limitations.

[0095] In step 102, in the preset control mode, after the first time duration of the relay being controlled to be disconnected, it is determined that the indoor unit meets the target temperature condition, and the relay is controlled to perform a corresponding action to start a target operation mode corresponding to the target temperature condition.

[0096] It should be noted that a relay is arranged on the power supply line connecting the indoor unit and the outdoor unit. The relay is used to control the conduction or disconnection of the power supply line. Understandably, when the relay is controlled to perform a disconnection action, the power supply to the outdoor unit is disconnected, so that the outdoor unit is powered off; when the relay is controlled to perform a closing action, the power supply to the outdoor unit is connected, so that the outdoor unit is powered on.

[0097] It should be noted that the indoor unit controls the relay to be disconnected for a first time duration, so that the outdoor unit is completely powered off, for completely clearing all power-off memories of the outdoor unit.

[0098] Exemplarily, the first time duration can be set to 40 seconds.

[0099] It should be noted that the target temperature condition indicates a preset temperature condition, and when the ambient temperature of the environment in which the indoor unit is located reaches the preset temperature condition, the relay is controlled to perform a corresponding action, so that the outdoor unit determines the target operation mode to be entered according to the corresponding action performed by the relay, and starts the target operation mode. The target temperature condition includes a heating condition and a cooling condition, the target operation mode corresponding to the heating condition is a heating operation mode, and the target operation mode corresponding to the cooling condition is a cooling operation mode.

[0100] It should be noted that controlling the relay to perform long-time power-off can make the outdoor unit clear all power-off memories; controlling the relay to perform short-time power-off can make the outdoor unit detect a voltage drop, memorize the voltage drop and time it, and the outdoor unit determines the target operation mode to be entered according to the detected voltage drop, so that the outdoor unit normally operates in the target operation mode based on the self-learning algorithm.

[0101] The control method of the air conditioning system provided by the application is applied to an indoor unit, and the control method comprises the following steps: determining that the indoor unit meets a condition of entering a preset control mode, controlling the indoor unit to enter the preset control mode, and controlling the outdoor unit to operate based on a self-learning algorithm in the preset control mode; in the preset control mode, after a first time length during which a relay is controlled to be turned off, it is determined that the indoor unit meets a target temperature condition, and the relay is controlled to perform a corresponding action to start a target operating mode corresponding to the target temperature condition; unlike the indoor unit controlling the outdoor unit to operate through a communication line in the related art, in the application, the indoor unit, in the preset control mode, judges that when the target temperature condition is met, the relay on the power supply line of the outdoor unit is controlled to perform a corresponding action under the target temperature condition, and the outdoor unit is controlled to operate in a target operating mode corresponding to the target temperature condition based on the self-learning algorithm according to the corresponding action performed by the relay. In this way, the application controls the power supply line, so that even if the indoor unit or the communication line fails, the outdoor unit can automatically control the outdoor unit to operate in the corresponding operating mode based on the corresponding action of the relay on the power supply line. The problem that the outdoor unit cannot normally operate when the indoor unit or the communication line fails in the related art is solved.

[0102] In some embodiments of the application, the step of determining that the indoor unit meets the condition of entering the preset control mode in step 101 comprises:

[0103] receiving first information sent by the cloud device, the first information indicating that the indoor unit will configure the control mode as the preset control mode; or

[0104] detecting that the indoor unit starts the preset control mode.

[0105] In one scenario, a cloud device is set, the cloud device is a network device built on a cloud platform, and the cloud device can also be referred to as a cloud diagnosis device. The cloud device is built-in with a cloud diagnosis system, and the cloud device can establish a communication connection with the air conditioning system in a wireless manner, a wireless and wired combined manner, or the like, to perform unified supervision of devices or systems, including but not limited to monitoring and diagnosis and management functions of operating parameters and operating states of the air conditioning system and air conditioning devices. The cloud diagnosis device can include but is not limited to a computer, a computer, and the like, which have input or output devices, to enable a user to perform human-computer interaction through the input or output devices. The input or output devices include but are not limited to a keyboard, a writing board, a microphone, a speaker, a display, and the like.

[0106] It should be noted that, during the running of the air conditioner at the user side, the cloud device monitors the running parameters of the air conditioning system and the air conditioning equipment in real time, and diagnoses the running state of the equipment, for managing the air conditioning system according to the diagnosis result. It can be understood that, when the cloud device side diagnoses that the air conditioning system fails during running, such as abnormality of indoor temperature sensor failure, communication failure, etc., the outdoor unit cannot establish a normal communication connection with the indoor unit, the first information is sent to the indoor unit, so that the indoor unit receives the first information, and triggers the indoor unit to enter the preset control mode, and the control mode of the indoor unit is configured as the preset control mode.

[0107] In another scenario, a diagnosis module is arranged in the indoor unit of the air conditioner, and the diagnosis module has functions of data processing, data communication and program running, etc., and can be driven by the core controller of the indoor unit of the air conditioner.

[0108] It should be noted that, during the running of the air conditioner at the user side, the diagnosis module of the air conditioner monitors the running parameters of the air conditioning system and the air conditioning equipment in real time, and diagnoses the running state of the equipment, for managing the air conditioning system according to the diagnosis result. It can be understood that, when the diagnosis module of the air conditioner diagnoses that the air conditioning system fails during running, such as abnormality of indoor temperature sensor failure, communication failure, etc., the outdoor unit cannot establish a normal communication connection with the indoor unit, the diagnosis system sends a signal to the indoor unit controller to open the preset control mode, and when the indoor unit detects that the indoor unit opens the preset control mode, the indoor unit enters the preset control mode.

[0109] Exemplarily, the first information can be information carrying an identifier of the preset control mode.

[0110] The embodiments of the present application provide conditions for triggering the indoor unit to enter the preset control mode in different scenarios, including receiving the first information issued by the cloud device, and detecting that the indoor unit provided with the diagnosis module opens the preset control mode, to realize real-time monitoring and fault diagnosis of the air conditioning system, so that when the air conditioning system fails or abnormally communicates, the indoor unit and the outdoor unit cannot normally communicate, the indoor unit can be triggered to enter the preset control mode in time, and the reliable running of the air conditioning system is ensured.

[0111] In some embodiments of the present application, the target temperature condition in step 102 includes a heating condition, and the control relay performs corresponding actions to start the target running mode corresponding to the target temperature condition, which can be realized by the following steps:

[0112] A first parameter is obtained, and the first parameter indicates the environment temperature of the environment where the indoor unit is located;

[0113] When it is determined that the first parameter meets the heating condition, the relay is controlled to perform n actions, each of which includes being closed first and then being opened, and after the n actions are performed, the relay is controlled to be closed to start the heating operation mode, wherein the relay is closed for a longer time than being opened during each action.

[0114] It should be noted that a large capacitor is arranged on the power supply line of the outdoor unit, and the power outage of the outdoor unit in a short time can be remembered and timed by the outdoor unit, so the opening time of the relay is relatively short, which is less than the closing time of the relay.

[0115] It can be understood that after the relay performs n actions of being opened for a short time, the outdoor unit can detect n voltage drops caused by the relay being opened for a short time and remember the voltage drop situation, which includes the number of voltage drops, the time of each drop, the time interval between multiple drops, etc., so that the outdoor unit can infer the number of times of opening of the relay, the opening time, the time interval between multiple openings, etc. based on the detected voltage drop situation, and further know the n actions of the relay, so as to know the ambient temperature of the environment in which the indoor unit is located meets the heating condition according to the n actions of the relay, so as to start the heating operation mode when the heating condition is met.

[0116] It should be noted that the heating condition is a heating-up start condition of the heating operation mode, and when the temperature of the environment in which the indoor unit is located is less than or equal to the first preset temperature, the heating-up start condition of the heating operation mode is met, which indicates that the air conditioner should work in the heating operation mode at this time.

[0117] It should be noted that n is an integer greater than 0, which can be set according to actual needs, and the present application does not make specific limitations thereto.

[0118] For example, when n is 2, the indoor unit controls the relay to perform the following two actions: first, perform the first action: control the relay to be closed for 76 seconds first, and then control the relay to be opened for 4 seconds, and then perform the second action: control the relay to be closed for 16 seconds first, and then control the relay to be opened for 4 seconds, which is used for the outdoor unit to detect two voltage drops according to the two actions, so as to determine that the heating operation mode should be started according to the two voltage drops. After the two actions are performed, the relay is controlled to be kept closed to continuously supply power to the outdoor unit, which is used for the outdoor unit to control the outdoor unit to work normally in the heating operation mode.

[0119] In the embodiments of the present application, the indoor unit executes the action of closing and then opening the relay on the power supply line for n times to convey "information" to the outdoor unit by n times of power supply line on-off, so that the outdoor unit determines that the target operation mode to be entered at present is the heating operation mode according to the action executed by the relay, and controls the outdoor unit to normally operate in the heating mode. The problem that the outdoor unit cannot normally operate when the indoor unit cannot issue communication information to the outdoor unit through the communication line is solved, and the reliability of air conditioner operation is improved.

[0120] In some embodiments of the present application, the target temperature condition in step 102 further includes a refrigeration condition, and the relay is controlled to execute a corresponding action to start the target operation mode corresponding to the target temperature condition. The target temperature condition can also be achieved by the following steps:

[0121] It is determined that the first parameter meets the refrigeration condition, and the relay is controlled to execute m actions, each action including closing and then opening, and after executing the m actions, the relay is controlled to be closed to start the refrigeration operation mode, wherein the closing time of the relay in each action is longer than the opening time.

[0122] It can be understood that after the relay is controlled to execute m actions of short-time opening, the outdoor unit can detect m voltage drops caused by the short-time opening of the relay, and can remember the voltage drop condition, including the number of voltage drops, the time of each drop, the time interval between multiple drops, etc., so that the outdoor unit can infer the number of relay openings, the opening time, the time interval between multiple openings, etc. based on the detected voltage drop condition, and further know the m actions executed by the relay, so as to know that the ambient temperature of the environment in which the indoor unit is located meets the refrigeration condition according to the m actions executed by the relay, so as to start the refrigeration operation mode under the condition of meeting the refrigeration condition.

[0123] It should be noted that the refrigeration condition is a temperature reaching start condition of the refrigeration operation mode, and when the temperature of the environment in which the indoor unit is located is greater than or equal to a second preset temperature, the temperature reaching start condition of the refrigeration operation mode is met, indicating that the air conditioner should work in the refrigeration operation mode at present. The second preset temperature is greater than the first preset temperature.

[0124] It should be noted that m is an integer greater than 0, and m is not equal to n.

[0125] Exemplarily, when m is 1, the indoor unit controls the relay to perform the following 1-time action: first controlling the relay to be closed for 76 seconds, and then controlling the relay to be opened for 4 seconds, for the outdoor unit to detect the 1-time voltage drop according to the 1-time action, to determine that the current target operation mode should be the cooling operation mode according to the 1-time voltage drop. After the 1-time action is performed, the relay is controlled to be kept in the closed state all the time, to continuously supply power to the outdoor unit, for the outdoor unit to control the outdoor unit to normally work in the cooling operation mode.

[0126] In the embodiments of the present application, the indoor unit performs the action of m times of closing and opening the relay on the power supply line for supplying power to the outdoor unit, to convey the "information" to the outdoor unit by m times of on-off of the power supply line, for the outdoor unit to determine that the target operation mode should be the cooling operation mode according to the action performed by the relay, to control the outdoor unit to normally work in the cooling mode. The problem that the outdoor unit cannot normally work when the indoor unit cannot issue the communication information to the outdoor unit through the communication line is solved, and the reliability of the air conditioner operation is improved.

[0127] In some embodiments of the present application, after the indoor unit is controlled to enter the preset control mode in step 101, the following steps can be further included:

[0128] Outputting first prompt information, the first prompt information being used to prompt that the control mode of the indoor unit is the preset control mode.

[0129] It should be noted that in the preset control mode, the indoor unit can actively initiate the state change prompt of the air conditioner by outputting the first prompt information, to prompt the user that the control mode of the indoor unit of the current air conditioner is the preset control mode.

[0130] It should be noted that the outputting manner of the first prompt information includes but is not limited to text, voice, picture, etc., to facilitate the user to intuitively know the current control mode of the indoor unit.

[0131] In some embodiments of the present application, after the indoor unit is controlled to enter the preset control mode in step 101, the following steps can be further included:

[0132] In the preset control mode, the working state information of the indoor unit is sent to the cloud device, the working state information indicating that the state of the indoor unit is a fault state or a normal state, to make the cloud device send second prompt information to the target device when the state of the indoor unit is the fault state, the second prompt information being used to prompt that the state of the indoor unit is the fault state.

[0133] In the fault state, the indoor unit and the outdoor unit cannot normally communicate, and the fault includes but is not limited to communication fault, sensor fault, etc.

[0134] It should be noted that when the cloud device receives the indoor unit state in the fault state, the second prompt information can be sent to the target device to trigger the active service request, and the operation and maintenance side of the cloud device provides corresponding operation and maintenance services according to the active service request.

[0135] It should be noted that the target device is a user terminal device on the cloud device side, which can include but is not limited to a mobile phone, a cellular phone, a smart phone, a tablet computer, a wearable device, a personal digital assistant (PDA), a portable computer, a wearable terminal device, etc. The target device receives the second prompt information sent by the cloud device, which is used to inform the user or the maintenance personnel of the target device of the current state of the air conditioner indoor unit, so that when the indoor unit is in a fault state, the relevant maintenance personnel or after-sales personnel can be notified in time to implement maintenance on the air conditioner according to the second prompt information.

[0136] In some embodiments of the present application, after the indoor unit is controlled to enter the preset control mode in step 101, the following steps can be further included:

[0137] Determine that the indoor unit meets the condition for exiting the preset control mode, and control the indoor unit to exit the preset control mode.

[0138] In some embodiments of the present application, determining that the indoor unit meets the condition for exiting the preset control mode includes one of the following:

[0139] Receiving a shutdown instruction;

[0140] Receiving a restart instruction;

[0141] Receiving a mode control instruction, the mode control instruction being used to control the indoor unit to enter a mode different from the cooling mode or the heating mode;

[0142] Receiving second information sent by the cloud device, the second information being used to instruct the indoor unit to exit the preset control mode;

[0143] Detecting that the indoor unit exits the preset control mode.

[0144] It should be noted that when the indoor unit receives the mode control instruction, which is used to control the indoor unit to enter a mode different from the cooling mode or the heating mode, it indicates that the user has no cooling or heating demand at this time, and the outdoor unit does not need to be controlled to run in the cooling or heating operation mode, triggering the indoor unit to exit the preset control mode.

[0145] It should be noted that the cloud device monitors and diagnoses the running state of the air conditioning system in real time, and when the diagnosis result indicates that the working state of the indoor unit returns to normal, the second information for instructing the indoor unit to exit the preset control mode is sent to the indoor unit, triggering the indoor unit to exit the preset control mode and return to the default control mode. In the default control mode, the indoor unit can send communication information to the outdoor unit through the communication line to control the outdoor unit to run.

[0146] Exemplarily, the second information can be information without carrying the identifier of the preset control mode, and can be regular communication information in the default control mode.

[0147] In some embodiments of the present application, before the step 102 of controlling the relay to perform the corresponding action, the following steps can be further included:

[0148] The third information is sent to the outdoor unit, and the third information is used to instruct the indoor unit to enter the preset control mode.

[0149] It can be understood that before the relay performs the corresponding action, the third information is sent to the outdoor unit after the control mode of the indoor unit is configured as the preset control mode, so that the outdoor unit can know that the indoor unit is currently in the preset control mode after receiving the third information, for triggering the outdoor unit to enter the preset control mode.

[0150] Exemplarily, the third information can be information carrying the identifier of the preset control mode.

[0151] In some embodiments of the present application, after the indoor unit exits the preset control mode, the following steps can be further included:

[0152] The fourth information is sent to the outdoor unit, and the fourth information is used to instruct the indoor unit to exit the preset control mode.

[0153] It can be understood that after the indoor unit exits the preset control mode, the fourth information is sent to the outdoor unit, so that the outdoor unit can know that the indoor unit has exited the preset control mode after receiving the fourth information, for triggering the outdoor unit to exit the preset control mode.

[0154] Exemplarily, the fourth information can be information without carrying the identifier of the preset control mode, and can be regular communication information in the default control mode.

[0155] Embodiments of the present application provide a control method of an air conditioning system, applied to an outdoor unit, as shown in Figure 2 The method includes the following steps:

[0156] Step 201, determining that the outdoor unit meets the condition of entering the preset control mode, and controlling the outdoor unit to enter the preset control mode.

[0157] In the preset control mode, the outdoor unit is controlled to operate based on the self-learning algorithm, and the preset control mode can also be referred to as an outdoor unit self-learning control mode.

[0158] It should be understood that the execution subject of the embodiment is the outdoor unit of the air conditioning system, and the outdoor unit of the air conditioning system has functions of data processing, data communication, and program running. Generally, the operation of each component in the outdoor unit of the air conditioning system can be driven by a core controller, and therefore the execution subject of the embodiment can also be the core controller of the outdoor unit, which can be a processor.

[0159] It should be noted that the preset control mode is a mode in which the state of the outdoor unit of the air conditioning system is a fault state. Understandably, if the outdoor unit meets the condition for entering the preset control mode during the operation of the air conditioning system, it indicates that the state of the outdoor unit of the air conditioning system is a fault state, the indoor unit and the outdoor unit cannot normally communicate, and the outdoor unit cannot receive the communication information issued by the indoor unit through the communication line. Therefore, the outdoor unit is controlled to enter the preset control mode. In the preset control mode, even if the indoor unit and the outdoor unit cannot normally communicate, the outdoor unit can still control the outdoor unit to automatically operate based on the self-learning algorithm. The communication information includes operation parameter information, control instruction information, and operation mode information for controlling the outdoor unit.

[0160] It should be noted that a default control mode can be set, and the default control mode is a mode in which the state of the outdoor unit of the air conditioning system is a normal state. Understandably, in the default control mode, the indoor unit and the outdoor unit can normally communicate, and the outdoor unit can receive the communication information issued by the indoor unit through the communication line to control the outdoor unit to perform corresponding actions according to the received communication information.

[0161] In step 202, in the preset control mode, a target operation mode of the outdoor unit is determined, and the outdoor unit is controlled to operate in the target operation mode.

[0162] It should be noted that the target operation mode includes a heating operation mode and a cooling operation mode, the heating operation mode corresponds to a heating condition, and the cooling operation mode corresponds to a cooling condition.

[0163] It should be noted that in the preset control mode, the indoor unit controls the relay to perform a corresponding action, so that the outdoor unit determines the target operation mode to be entered according to the corresponding action performed by the relay, and starts the target operation mode to control the outdoor unit to operate based on the self-learning algorithm.

[0164] The control method of the air conditioning system provided in the application is applied to an outdoor unit, and the control method comprises the following steps: determining that the outdoor unit meets a condition for entering a preset control mode, controlling the outdoor unit to enter the preset control mode, controlling the outdoor unit to run based on a self-learning algorithm in the preset control mode, determining a target running mode of the outdoor unit in the preset control mode, and controlling the outdoor unit to run in the target running mode. Different from the indoor unit controlling the outdoor unit to run through a communication line in the related art, in the application, the indoor unit determines the target running mode according to the corresponding action of a relay when the condition for entering the preset control mode is met in the preset control mode, and controls the outdoor unit to run based on the self-learning algorithm in the target running mode. In this way, the application controls the power supply line, so that the outdoor unit can automatically control the outdoor unit to run in the corresponding running mode based on the corresponding action of the relay on the power supply line even when the indoor unit or the communication line fails. The problem that the outdoor unit cannot normally run when the indoor unit or the communication line fails in the related art is solved.

[0165] In some embodiments of the application, the step of determining that the outdoor unit meets the condition for entering the preset control mode in step 201 can comprise the following steps:

[0166] detecting that there is a voltage drop within a second time length after the outdoor unit is powered on; and

[0167] receiving third information sent by the indoor unit within a third time length after the outdoor unit is powered on, or not receiving the third information sent by the indoor unit, the third information being used to indicate that the indoor unit enters the preset control mode.

[0168] It should be noted that the relay is arranged on the power supply line connecting the indoor unit and the outdoor unit, and when the relay performs a short-time power-off action, the power supply line of the outdoor unit is disconnected, which can enable the outdoor unit to detect that there is a voltage drop, memorize the voltage drop, and time the voltage drop. Therefore, the outdoor unit detects that there is a voltage drop within the second time length after the outdoor unit is powered on, which indicates that the power supply line of the outdoor unit has been disconnected, and then the voltage drop condition can be further determined. Specifically, the outdoor unit determines the target running mode to be entered according to the detected voltage drop condition, which is used to control the outdoor unit to normally run based on the self-learning algorithm in the target running mode.

[0169] And, within a third time length after the outdoor unit is powered on, the outdoor unit does not receive the information sent by the indoor unit, indicating that a communication failure occurs, the outdoor unit cannot accept the communication information sent by the indoor unit, and the outdoor unit enters a preset control mode. Or within the third time length after the outdoor unit is powered on, the outdoor unit receives the third information sent by the indoor unit, indicating that the indoor unit is currently in the preset control mode, and the outdoor unit enters the preset control mode. Exemplarily, the third information can be information carrying an identifier of the preset control mode.

[0170] Exemplarily, the second time length can be 2 minutes, or other time length, which can be set according to actual needs.

[0171] Exemplarily, the third time length can be 1 to 2 minutes, or other time length, which can be set according to actual needs.

[0172] In some embodiments of the present application, the target operation mode of the outdoor unit determined in step 202 can be achieved by the following steps:

[0173] The second parameter is obtained, and the second parameter indicates a parameter related to the voltage drop detected by the outdoor unit after the indoor unit controls the relay to perform a corresponding action;

[0174] The target operation mode of the outdoor unit is determined based on the second parameter.

[0175] It should be noted that a large capacitor is arranged on the power supply line of the outdoor unit, and the power outage of the outdoor unit in a short time can be remembered and timed by the outdoor unit, so as to obtain the parameter related to the voltage drop. The second parameter can include, but is not limited to, the number of voltage drops, the time length of each drop, the time interval between multiple drops, etc.

[0176] It should be noted that the indoor unit controls the relay on the power supply line to perform a corresponding opening and / or closing action, which is used for the outdoor unit to detect the voltage drop caused by the short-time opening of the relay, and to determine the target operation mode of the outdoor unit according to the parameter related to the detected voltage drop. It can be understood that different voltage drop times can correspond to heating operation mode or cooling operation mode.

[0177] In the embodiments of the present application, the indoor unit controls the relay on the power supply line to perform a corresponding action, so that the outdoor unit obtains "information" by using the on-off of the power supply line, determines the target operation mode to be entered according to the corresponding action of the relay, and controls the outdoor unit to normally operate in the target operation mode. The problem that the outdoor unit cannot normally operate when the outdoor unit cannot receive the communication information issued by the indoor unit through the communication line is solved, and the reliability of the air conditioner operation is improved.

[0178] In some embodiments of the present application, the second parameter includes the number of voltage drops, and the target operation mode of the outdoor unit is determined based on the second parameter. The determination can be achieved by the following steps:

[0179] In the case of n times of voltage drops, the target operation mode of the outdoor unit is determined as the heating operation mode.

[0180] It should be noted that when the ambient temperature of the environment in which the indoor unit is located meets the heating condition, the relay is controlled to perform n actions. In this way, n times of voltage drops caused by the short-time opening of the relay can be detected on the outdoor unit side, so that it is known that the target operation mode of the outdoor unit is the heating operation mode. When the outdoor unit cannot receive the communication information issued by the indoor unit through the communication line, the voltage drop obtained by the on-off detection of the power supply line can still be used to control the outdoor unit to enter the corresponding operation mode, thereby improving the reliability of the air conditioner operation.

[0181] It should be noted that n is an integer greater than 0, which can be set according to actual needs, and the present application does not make a specific limitation.

[0182] For example, when n is 2, the indoor unit controls the relay to perform the following two actions: first, the first action is performed: the relay is controlled to be closed for 76 seconds, and then the relay is controlled to be opened for 4 seconds; then the second action is performed: the relay is controlled to be closed for 16 seconds, and then the relay is controlled to be opened for 4 seconds. The outdoor unit detects 2 times of voltage drops according to the 2 actions, so as to determine that the heating operation mode should be started according to the 2 times of voltage drops.

[0183] In some embodiments of the present application, the target operation mode of the outdoor unit is determined based on the second parameter, which can also be achieved by the following steps:

[0184] In the case of m times of voltage drops, the target operation mode of the outdoor unit is determined as the cooling operation mode.

[0185] It should be noted that when the ambient temperature of the environment in which the indoor unit is located meets the cooling condition, the relay is controlled to perform m actions. In this way, m times of voltage drops caused by the short-time opening of the relay can be detected on the outdoor unit side, so that it is known that the target operation mode of the outdoor unit is the cooling operation mode. When the outdoor unit cannot receive the communication information issued by the indoor unit through the communication line, the voltage drop obtained by the on-off detection of the power supply line can still be used to control the outdoor unit to enter the corresponding operation mode, thereby improving the reliability of the air conditioner operation.

[0186] It should be noted that m is an integer greater than 0, and m is not equal to n.

[0187] Exemplarily, when m is 1, the indoor unit controls the relay to perform the following 1-time action: controlling the relay to be closed for 76 seconds, and then controlling the relay to be opened for 4 seconds, so that the outdoor unit detects a 1-time voltage drop according to the 1-time action, to determine that the current should start the heating operation mode according to the 1-time voltage drop.

[0188] In some embodiments of the present application, after determining the target operation mode of the outdoor unit based on the second parameter, the step of controlling the outdoor unit to operate in the target operation mode in step 202 can be implemented by the following steps:

[0189] Obtaining a third parameter, the third parameter indicating a related parameter when the outdoor unit operates;

[0190] Determining an outdoor unit operating parameter of the outdoor unit based on the second parameter and the third parameter;

[0191] Controlling the outdoor unit to operate in the target operation mode based on the outdoor unit operating parameter.

[0192] In some embodiments of the present application, the outdoor unit operating parameter includes one or more of the following:

[0193] The operating frequency of the compressor of the outdoor unit;

[0194] The fan speed of the outdoor unit;

[0195] The opening degree of the four-way valve of the condenser of the outdoor unit;

[0196] The opening degree of the electronic expansion valve of the condenser of the outdoor unit.

[0197] It should be noted that one or more of the outdoor unit operating parameters can be selected for output according to actual needs, which can be set according to actual needs, and the present application does not make specific limitations thereto.

[0198] In some embodiments of the present application, the third parameter includes one or more of the following: the operating time of the compressor, the historical operating frequency of the compressor, the fault type of the outdoor unit, the temperature of the condenser of the outdoor unit, the ambient temperature of the outdoor unit, the fan speed of the outdoor unit, the opening degree of the four-way valve of the condenser, the opening degree of the electronic expansion valve of the condenser, the model parameter of the refrigerant of the condenser, and the pressure parameter of the refrigerant of the condenser.

[0199] It should be noted that one or more of the related parameters can be selected according to actual needs, which can be set according to actual needs, and the present application does not make specific limitations thereto.

[0200] It should be noted that in the embodiments of the present application, based on the related parameters of the voltage drop indicated by the second parameter, the target operation mode of the outdoor unit is determined, and the third parameter is taken as the input and the outdoor unit operation parameter is taken as the output, the specific value of the outdoor unit operation parameter is determined based on the self-learning algorithm, and the outdoor unit is controlled to run in the heating operation mode or the cooling operation mode according to the calculated outdoor unit operation parameter. In this way, when the outdoor unit cannot receive the communication information issued by the indoor unit through the communication line, it can still know that the outdoor unit should enter the heating operation mode or the cooling operation mode, and automatically control the outdoor unit to run in the heating operation mode or the cooling operation mode, maintain the consistency of the operation mode of the outdoor unit and the indoor unit, and improve the reliability of the air conditioner operation.

[0201] In some embodiments of the present application, after the outdoor unit is controlled to enter the preset control mode in step 201, the following steps are further included:

[0202] The condition for the outdoor unit to exit the preset control mode is determined, and the outdoor unit is controlled to exit the preset control mode.

[0203] In some embodiments of the present application, the condition for the outdoor unit to exit the preset control mode is determined, including one of the following:

[0204] A shutdown instruction is received;

[0205] A restart instruction is received;

[0206] The fourth information sent by the indoor unit is received, and the fourth information is used to indicate that the indoor unit exits the preset control mode.

[0207] It should be noted that when the outdoor unit receives the fourth information sent by the indoor unit for indicating that the indoor unit exits the preset control mode, it indicates that the indoor unit has exited the preset control mode at present, and the outdoor unit is controlled to exit the preset control mode.

[0208] Exemplarily, the fourth information can be information without carrying the identifier of the preset control mode, and can be regular communication information in the default control mode.

[0209] It should be noted that the descriptions of the same steps and contents in other embodiments in the present embodiment can refer to the descriptions in other embodiments, and will not be described here.

[0210] In an actual scenario, the embodiments of the present application provide a control device of an air conditioning system, which comprises: an air conditioner diagnosis device, an indoor unit, and an outdoor unit; wherein,

[0211] The air conditioner diagnosis device comprises a diagnosis system for monitoring and controlling the operation state of the indoor unit and the outdoor unit in real time;

[0212] Referring toFigure 3 or Figure 4 As shown in FIG. 3, the indoor unit 302, arranged at the user side, comprises an indoor unit control system 3021 for controlling the indoor unit 302 to operate according to the control instructions issued by the diagnosis system.

[0213] Referring to FIG. 4, the outdoor unit 303, arranged at the user side, comprises an outdoor unit control system 3031 for controlling the outdoor unit 303 to operate according to the control instructions of the cloud platform and / or the indoor unit 302. Figure 3 or Figure 4 As shown in FIG. 3, the indoor unit 302, arranged at the user side, comprises an indoor unit control system 3021 for controlling the indoor unit 302 to operate according to the control instructions issued by the diagnosis system.

[0214] It should be noted that the air conditioner diagnosis device can be a third-party device independent of the air conditioner, which comprises a cloud device provided with a cloud diagnosis system, or an air conditioner diagnosis device built in the air conditioner, which is provided with a diagnosis system, or a diagnosis system added on the basis of the original control system of the indoor unit of the air conditioner, which can realize the functions of the above diagnosis system, and the specific settings can be made according to actual needs, which are not limited in the present application.

[0215] Exemplarily, in one case, referring to FIG. 3, an air conditioner control device 300 based on a cloud diagnosis system 301 is shown, wherein the cloud diagnosis system 301 monitors and controls the operating states of the indoor unit 302 and the outdoor unit 303 in real time, and issues relevant control instructions to the indoor unit 302 to control the indoor unit 302 to operate in a preset control mode, and then the indoor unit 302 controls the outdoor unit 303 to enter the corresponding mode of operation by controlling the conduction or disconnection of the power supply line 304 of the outdoor unit 303. Figure 3 Exemplarily, in another case, referring to FIG. 4, an air conditioner control device 400 based on an air conditioner built-in diagnosis system 401 is shown, wherein the air conditioner built-in diagnosis system 401 monitors and controls the operating states of the indoor unit 302 and the outdoor unit 303 in real time, and issues relevant control instructions to the indoor unit 302 to control the indoor unit 302 to operate in a preset control mode, and then the indoor unit 302 controls the outdoor unit 303 to enter the corresponding mode of operation by controlling the conduction or disconnection of the power supply line 304 of the outdoor unit 303.

[0216] Figure 4 Exemplarily, in another case, referring to FIG. 4, an air conditioner control device 400 based on an air conditioner built-in diagnosis system 401 is shown, wherein the air conditioner built-in diagnosis system 401 monitors and controls the operating states of the indoor unit 302 and the outdoor unit 303 in real time, and issues relevant control instructions to the indoor unit 302 to control the indoor unit 302 to operate in a preset control mode, and then the indoor unit 302 controls the outdoor unit 303 to enter the corresponding mode of operation by controlling the conduction or disconnection of the power supply line 304 of the outdoor unit 303.

[0217] ​The embodiment of the application provides a new air conditioner system control method, by setting control systems in the indoor unit and the outdoor unit respectively, so that when the air conditioner is normally running, the indoor unit control system can be set as a master mode and the outdoor unit control system can be set as a slave mode. When the trigger condition of the preset control mode is met, the outdoor unit control system is automatically upgraded to the preset control mode, that is, the outdoor unit self-learning control mode, so that the outdoor unit can control the outdoor unit to normally run through the self-learning algorithm. The problem that the outdoor unit cannot run when the indoor unit or the communication line fails or the equipment abnormally runs in the existing single control system air conditioner is solved, the air conditioner can normally run, and the running reliability of the air conditioner is improved.

[0218] In an actual scene, the embodiment of the application provides an indoor unit control method based on a diagnosis system, which can be applied to the control device of the air conditioner system. Figure 5 As shown in the figure, the specific description is as follows:

[0219] Step 501, the indoor unit runs in a default control mode.

[0220] The default control mode is a conventional control mode, that is, the mode of the air conditioner in normal running.

[0221] Step 502, it is judged whether the indoor unit meets the entering condition of the "outdoor unit self-learning control mode".

[0222] In one scenario, the diagnosis system issues a "outdoor unit self-learning control mode" control instruction to the indoor unit, and the indoor unit receives the control instruction and meets the entering condition of the "outdoor unit self-learning control mode".

[0223] It should be noted that in the outdoor unit self-learning control mode, the outdoor unit adopts a self-learning algorithm to determine the running parameters of each device and automatically controls each device of the outdoor unit to run according to the determined running parameters.

[0224] It should be noted that when the air conditioner is running at the user side, the diagnosis system monitors the running state and / or running parameter of each device of the air conditioner at the user side, and diagnoses the running state and / or running parameter of each device of the air conditioner. When the diagnosis result shows that the trigger condition of the "outdoor unit self-learning control mode" is met, the "outdoor unit self-learning control mode" is triggered, and the control instruction of the "outdoor unit self-learning control mode" is issued to the indoor unit. The trigger condition includes but is not limited to the occurrence of abnormalities such as air conditioner outdoor unit communication failure and air conditioner indoor unit temperature sensor failure.

[0225] It should be noted that in one case, when the diagnostic system is the aforementioned cloud diagnostic system, when the air conditioner is running, the cloud diagnostic system on the cloud equipment of the third-party management platform on the operation and maintenance side monitors the running state and / or running parameter of each device of the air conditioner on the user side, and diagnoses the running state and / or running parameter of each device of the air conditioner, when the diagnostic result shows that the trigger condition of the "outdoor unit self-learning control mode" is met, the "outdoor unit self-learning control mode" is triggered, and the control instruction of the "outdoor unit self-learning control mode" is issued to the indoor unit. In this way, the cloud diagnostic system identifies the abnormality, triggers and controls the indoor unit to start the "outdoor unit self-learning control mode", and can timely notify the relevant operation and maintenance personnel of the abnormality through the cloud equipment of the third-party management platform.

[0226] It should be noted that in another case, when the diagnostic system is the aforementioned built-in diagnostic system or diagnostic module of the air conditioner, when the air conditioner is running, the built-in diagnostic system or diagnostic module of the air conditioner monitors the running state and / or running parameter of each device of the air conditioner on the user side, and diagnoses the running state and / or running parameter of each device of the air conditioner, when the diagnostic result shows that the trigger condition of the "outdoor unit self-learning control mode" is met, the "outdoor unit self-learning control mode" is triggered, and the control instruction of the "outdoor unit self-learning control mode" is issued to the indoor unit. In this way, the built-in diagnostic system or diagnostic module of the air conditioner identifies the abnormality, and directly triggers and controls the indoor unit to start the "outdoor unit self-learning control mode".

[0227] Step 503, control the indoor unit to enter the "outdoor unit self-learning control mode".

[0228] The indoor unit of the air conditioner on the user side runs in the conventional mode, when the indoor unit control system receives the control instruction of the "outdoor unit self-learning control mode" issued by the diagnostic system, the entering condition of the "outdoor unit self-learning control mode" is met, and the indoor unit of the air conditioner on the user side is controlled to enter and start the "outdoor unit self-learning control mode".

[0229] It should be noted that when the indoor unit receives the control instruction of the "outdoor unit self-learning control mode" issued by the diagnostic system, it indicates that the air conditioning system has occurred air conditioner outdoor unit communication failure, or has occurred air conditioner indoor unit temperature sensor failure and other abnormalities. The current indoor unit needs to be switched from the conventional mode to the "outdoor unit self-learning control mode" to control the outdoor unit alone.

[0230] Further, the indoor unit sends a communication instruction carrying an "outdoor unit self-learning control mode" identifier to the outdoor unit. In the embodiment of the present application, after the indoor unit enters and starts the "outdoor unit self-learning control mode", the following actions are performed: the "outdoor unit self-learning control mode" identifier is carried in a conventional communication instruction, and the original communication mode is changed to indicate to the outdoor unit that the indoor unit has entered the "outdoor unit self-learning control mode".

[0231] Step 504: The indoor unit changes the control logic of the relay of the power supply line of the outdoor unit.

[0232] In the embodiment of the present application, after the indoor unit enters and starts the "outdoor unit self-learning control mode", the following actions are performed: the control logic of the relay of the power supply line of the outdoor unit is changed, specifically including:

[0233] The relay of the power supply line of the outdoor unit is controlled to be off for 40 seconds to completely power off the outdoor unit. The outdoor unit will lose the voltage drop memory in the case of long-time complete power off, to clear all power-off memories of the outdoor unit.

[0234] Further, after clearing all power-off memories of the outdoor unit, the ambient temperature of the indoor unit is acquired, and the relay of the power supply line of the outdoor unit is controlled to perform the following operations according to the ambient temperature of the indoor unit:

[0235] In an actual scenario, when the ambient temperature of the indoor unit meets the heating mode reach temperature start condition, the indoor unit first controls the relay of the power supply line of the outdoor unit to be closed for 76 seconds, then controls the relay to be off for 4 seconds to cause the outdoor unit to be powered off for a short time, then controls the relay to be closed for 16 seconds again, then controls the relay to be off for 4 seconds again to cause the outdoor unit to be powered off for a short time again, and finally controls the relay to be kept closed. In this way, the indoor unit controls the relay to perform two opening and closing operations, so that the outdoor unit is powered off for two short times in succession, and the outdoor unit detects two voltage drops and memorizes the two voltage drop conditions. It can be understood that when the ambient temperature of the indoor unit meets the heating mode reach temperature stop condition, the indoor unit controls the relay to be off to cut off the power supply to the outdoor unit, so that the outdoor unit exits the heating mode.

[0236] In an actual scenario, when the ambient temperature of the indoor unit meets the temperature reach-up start condition of the cooling mode, the indoor unit controls the relay of the power supply line of the outdoor unit to be closed for 76 seconds, and then controls the relay to be opened for 4 seconds, so that the outdoor unit is powered off for a short time, and finally controls the relay to be kept closed. In this way, the indoor unit controls the relay to perform an opening and closing operation, so that the outdoor unit is powered off for a short time, and the outdoor unit detects a voltage drop once. It can be understood that when the ambient temperature of the indoor unit meets the temperature reach-up stop condition of the cooling mode, the indoor unit controls the relay to be opened to cut off the power supply to the outdoor unit, so that the outdoor unit exits the cooling mode.

[0237] In the embodiments of the present application, it can be understood that opening the relay means cutting off the power supply to the outdoor unit, and closing the relay means supplying power to the outdoor unit. Therefore, the indoor unit controls the relay to perform two opening and closing operations, so that the outdoor unit detects two voltage drops, which are used to determine that the current user sets the heating mode when the outdoor unit detects two voltage drops; it can be understood that the indoor unit controls the relay to perform one opening and closing operation, so that the outdoor unit detects one voltage drop, which is used to determine that the current user sets the cooling mode when the outdoor unit detects one voltage drop.

[0238] Step 505, judging whether the indoor unit meets the exit condition of the "outdoor unit self-learning control mode".

[0239] Step 506, controlling the indoor unit to exit the "outdoor unit self-learning control mode".

[0240] When the indoor unit meets any condition for exiting the "outdoor unit self-learning control mode", the indoor unit is controlled to exit the "outdoor unit self-learning control mode". The conditions for exiting the "outdoor unit self-learning control mode" include, but are not limited to, receiving a control instruction for exiting the "outdoor unit self-learning control mode" issued by a diagnostic system, receiving a shutdown instruction of a user, and receiving an exit instruction of the cooling mode or the heating mode.

[0241] It should be noted that when the indoor unit receives the control instruction for exiting the "outdoor unit self-learning control mode" issued by the diagnostic system, it indicates that the diagnostic system may have found that all functions of the air conditioning system are in a normal state after continuously monitoring the air conditioning system, and then the indoor unit is controlled to exit the "outdoor unit self-learning control mode".

[0242] It should be noted that when the indoor unit receives the shutdown instruction of the user, it indicates that the air conditioning system does not need to work at this time, and the outdoor unit does not need to be controlled to run alone, and then the indoor unit is controlled to exit the "outdoor unit self-learning control mode".

[0243] It should be noted that when the indoor unit receives an exit instruction of the cooling mode or the heating mode, it indicates that the user does not have a cooling or heating demand at this time, and there is no need to start the compressor and other related devices of the outdoor unit, so the indoor unit exits the "outdoor unit self-learning control mode".

[0244] In the embodiments of the present application, the indoor unit can actively initiate a prompt of state change in the "outdoor unit self-learning control mode" to prompt the user of the current air conditioner working state.

[0245] In the embodiments of the present application, the indoor unit can upload the fault running state of the fault air conditioner to the cloud operation and maintenance system in the "outdoor unit self-learning control mode", for the cloud operation and maintenance system to trigger an active service request as needed. The active service request includes that the cloud operation and maintenance system actively starts a service process to notify the relevant maintenance personnel or after-sales personnel to timely visit and repair and maintain the fault air conditioner.

[0246] In an actual scenario, the embodiments of the present application provide an outdoor unit control method based on a diagnosis system, which can be applied to the control device of the air conditioner system as described above, as shown in Figure 6 The specific description is as follows.

[0247] Step 601, the outdoor unit operates in a default control mode.

[0248] Step 602, the outdoor unit meets the entering condition of the "outdoor unit self-learning control mode".

[0249] Step 603, control the outdoor unit to enter the "outdoor unit self-learning control mode".

[0250] The outdoor unit of the user-side air conditioner operates in a conventional mode, and when the outdoor unit meets all conditions for entering the "outdoor unit self-learning control mode", the outdoor unit enters the "outdoor unit self-learning control mode". The conditions for entering the "outdoor unit self-learning control mode" include but are not limited to that no communication instruction is received within 2 minutes after the outdoor unit is powered on, or a communication instruction carrying an identification of the "outdoor unit self-learning control mode" is received, and a voltage drop is detected within 2 minutes after the outdoor unit is powered on.

[0251] It should be noted that when no communication instruction is received within 2 minutes after the outdoor unit is powered on, or a communication instruction carrying an identification of the "outdoor unit self-learning control mode" is received, it indicates that a communication line fault from the outdoor unit to the indoor unit may have occurred. At the same time, when the outdoor unit detects a voltage drop, it indicates that the indoor unit indicates the operating mode of the air conditioner system by controlling the opening or closing of the power supply line of the outdoor unit, so that even if a communication line fault occurs, information can be conveyed to the outdoor unit using the power supply line, so that the outdoor unit can be controlled independently according to the voltage drop when the voltage drop is detected.

[0252] It should be noted that the manner in which the outdoor unit receives the communication instruction carrying the "outdoor unit self-learning control mode" identifier can be wireless communication or other manners. As long as the function of informing the outdoor unit to enter the "outdoor unit self-learning control mode" through any manner can be realized when the communication line from the indoor unit to the outdoor unit fails, the present application does not limit this.

[0253] Step 604, the outdoor unit determines the operation mode of the outdoor unit according to the detected number of voltage drops.

[0254] When the outdoor unit detects a voltage drop, the operation mode of the outdoor unit is determined according to the detected number of voltage drops (corresponding to the target operation mode described above). The operation mode of the air conditioner includes heating mode and cooling mode. When the outdoor unit detects two voltage drops, it is determined that the current outdoor unit should enter the heating mode; when the outdoor unit detects one voltage drop, it is determined that the current outdoor unit should enter the cooling mode; when the outdoor unit detects no voltage drop, it is determined that the current outdoor unit does not run. In this way, the operation mode of the outdoor unit is determined according to the number of voltage drops, and the operation mode of the outdoor unit is kept consistent with the mode set by the user.

[0255] It should be noted that the present application embodiment gives the setting of the number of voltage drops as two times when the outdoor unit determines the operation mode as the heating mode, and the number of voltage drops can also be set as other times when the outdoor unit determines the operation mode as the heating mode. The specific setting can be made according to the actual demand, and the present application embodiment does not limit this.

[0256] It should be noted that the present application embodiment gives the setting of the number of voltage drops as one time when the outdoor unit determines the operation mode as the cooling mode, and the number of voltage drops can also be set as other times when the outdoor unit determines the operation mode as the cooling mode. The specific setting can be made according to the actual demand, and the present application embodiment does not limit this.

[0257] Step 605, the outdoor unit controls the outdoor unit to run in the corresponding operation mode based on the outdoor unit operation parameters calculated by the self-learning algorithm.

[0258] In one case, after the outdoor unit determines the operation mode as the cooling mode or the heating mode, the outdoor unit operation parameters are calculated based on the self-learning algorithm in the corresponding operation mode, and the specific steps include:

[0259] Firstly, relevant parameters are acquired. The relevant parameters include, but are not limited to, power supply drop frequency, power supply drop time interval, compressor running time, historical running parameter trajectory, fault type of the outdoor unit, temperature of the condenser of the outdoor unit, ambient temperature of the outdoor unit, outdoor unit wind speed, electronic expansion valve opening degree, refrigerant model parameter, refrigerant pressure parameter, and the like.

[0260] Secondly, the relevant parameters are input into an algorithm model corresponding to a self-learning algorithm, and outdoor unit running parameters are obtained by reasoning of the self-learning algorithm. The outdoor unit running parameters include, but are not limited to, compressor frequency of the outdoor unit, fan speed, electronic expansion valve opening degree, four-way valve opening degree, and the like.

[0261] In the embodiment of the application, the compressor running frequency obtained by the self-learning algorithm is compared with the compressor frequency under the severe fault drop frequency, and the frequency with a lower running frequency value is used for running. Understandably, the compressor does not need to work in the non-refrigeration mode or the non-heating mode, and the compressor is not started.

[0262] Finally, the outdoor unit is controlled to run based on the outdoor unit running parameters.

[0263] In another case, after the outdoor unit determines that the running mode is the refrigeration mode or the heating mode, the compressor running frequency of the outdoor unit is calculated according to the compressor running time, the ambient temperature of the outdoor unit, and the compressor frequency limiting rule corresponding to the ambient temperature of the outdoor unit in the full temperature range. The compressor frequency limiting rule corresponding to the ambient temperature of the outdoor unit is used to control the compressor to run at a reduced frequency under the current outdoor ambient temperature. For example, if the compressor running time is less than 30 minutes, the compressor is controlled to run at 85% of the frequency corresponding to the current ambient temperature of the outdoor unit; if the compressor running time is greater than or equal to 30 minutes, the compressor is controlled to run at 70% of the frequency corresponding to the current ambient temperature of the outdoor unit.

[0264] Step 606: The outdoor unit meets the exit condition of the "outdoor unit self-learning control mode".

[0265] Step 607: The outdoor unit is controlled to exit the "outdoor unit self-learning control mode".

[0266] When the outdoor unit meets any condition for exiting the "outdoor unit self-learning control mode", the outdoor unit is controlled to exit the "outdoor unit self-learning control mode". The conditions for exiting the "outdoor unit self-learning control mode" include, but are not limited to, detecting that the power supply voltage of the outdoor unit changes, the change indicating power failure and / or restart, and receiving a control instruction sent by the indoor unit without carrying an identification of the "outdoor unit self-learning control mode".

[0267] It should be noted that when the outdoor unit detects that the power supply voltage of the outdoor unit changes, the change indicates power failure and / or restart, indicating that the power supply line of the outdoor unit is cut off at this time, and the outdoor unit cannot continue to be controlled, and is forced to exit the "outdoor unit self-learning control mode".

[0268] It should be noted that when the outdoor unit receives the control instruction sent by the indoor unit without carrying the "outdoor unit self-learning control mode" identifier, it indicates that the communication line between the indoor unit and the outdoor unit has recovered from the fault state to the normal state at this time, and the indoor unit can work normally through the communication line and send normal control instructions to the outdoor unit. At this time, the outdoor unit is controlled to exit the "outdoor unit self-learning control mode", and the control mode of the outdoor unit is switched back to the control mode controlled by the indoor unit.

[0269] In the embodiment of the application, the indoor unit judges when the target temperature condition is met in the preset control mode, controls the relay on the power supply line of the outdoor unit to execute the corresponding action under the target temperature condition, and controls the outdoor unit to run in the target operation mode corresponding to the target temperature condition based on the self-learning algorithm. In this way, the power supply line is controlled, so that even if the indoor unit or the communication line fails, the outdoor unit can automatically control the outdoor unit to run continuously in the corresponding cooling operation mode or heating operation mode based on the corresponding action of the relay on the power supply line, achieve the effect of cooling or heating, effectively reduce the influence on the operation of the outdoor unit when the indoor unit or the communication line fails, and improve the operation reliability of the air conditioner.
