[0048] The multi-connected air conditioner involved in the present invention includes one / group of outdoor units and multiple indoor units. The multi-connected main control system includes a main control system, which is electrically connected to the outdoor unit and multiple indoor units and can transmit data and control signals.

[0049] For the fault troubleshooting method of the multi-connected air conditioner provided by the first aspect embodiment of the present invention, please refer to Figure 1 , including:

[0050] S100. In response to receiving a fault signal, sequentially detect the current status of each indoor unit, and determine the operating state of the corresponding indoor unit according to the current status of each indoor unit; wherein, the operating state includes a healthy state and at least one fault state, and the fault state corresponds to the fault type of the indoor unit.

[0051] In step S100, when the main control system receives a fault signal (from any connected indoor unit or outdoor unit, or generated by the user / maintenance personnel through the control component), the main control system will start the detection process. During this detection process, the main control system will sequentially check the current status of each indoor unit. The current status includes but is not limited to various indicators such as the temperature, operating efficiency, component status, software status, and communication status of the indoor unit. According to the current status of each indoor unit, the main control system will determine the operating state of the corresponding indoor unit; wherein, the operating state of the indoor unit is divided into two main types: a healthy state and at least one fault state. The healthy state indicates that the indoor unit is operating normally, while the fault state indicates that there is some problem or fault with the indoor unit. Furthermore, the fault state corresponds to the specific fault type of the indoor unit, that is, different fault states may represent different fault types, such as sensor failure, motor failure, circuit failure, software failure, etc.

[0052] S110. When the operating state of any indoor unit is a fault state, control the prompting component of the corresponding indoor unit to emit a warning signal.

[0053] In step S110, if during the detection process, the operating state of any indoor unit is determined to be a fault state, then the main control system will control the prompting component (such as a warning light, buzzer, etc.) of the indoor unit to emit a warning signal. The warning signal is intended to notify the user or maintenance personnel that there is a fault with the indoor unit and further inspection and repair are required.

[0054] In the embodiment of the present invention, when a fault occurs in the multi-connected air conditioner, the operating state of each indoor unit can be sequentially determined. When any indoor unit is in a fault state, the prompting component of the indoor unit is controlled to emit a warning signal, which can assist the user and maintenance personnel in quickly locating the faulty indoor unit and determining the fault type of the indoor unit, reducing the difficulty of maintenance for the maintenance personnel and improving the user experience.

[0055] In some embodiments, the step of sequentially detecting the current status of each indoor unit and determining the operating state of the corresponding indoor unit according to the current status of each indoor unit specifically includes:

[0056] S101. Switch all indoor units to the powered-on state.

[0057] In step S101, power on all connected indoor units to start their electrical systems for detection. The detection process may include detecting the powered-on status of the indicator lights of the corresponding components. After power-on, the indicator lights of each component are lit. Among them, the indicator lights of DCPUMP--LTXD (2 lights light up in a cycle), PMV1 (CN10), SWING2 (CN35), and SWING1 (CN11 / CN11-1) are lit after power-on.

[0058] S102. Detect the powered-on status of all hardware of each indoor unit.

[0059] In step S102, after the system is powered on, it will check whether all hardware parts of each indoor unit are smoothly connected to the circuit and in a working state; among them, all hardware includes but is not limited to various components such as sensors, circuit boards, fans, and controllers.

[0060] S103. When at least one of all the hardware of any indoor unit is not powered on, the operating state of the corresponding indoor unit is the first fault state.

[0061] In step S103, during the detection process, if it is found that at least one hardware of any indoor unit is not normally powered on, that is, at least one component does not receive or fails to maintain power supply and is in a state of being unable to work properly. At this time, the main control system will determine the operating state of the indoor unit with the hardware power-on problem as the first fault state. The first fault state indicates that there is a basic hardware fault in the indoor unit, which needs to be further investigated and repaired, helping maintenance personnel quickly identify and distinguish the current fault type of the indoor unit for targeted maintenance and service.

[0062] In some embodiments, after the step of detecting the powered-on status of all hardware of each indoor unit, it further includes:

[0063] S1021. When all the hardware of any indoor unit is powered on, detect the communication status between each indoor unit and the outdoor unit.

[0064] In step S1021, when all the hardware of any indoor unit is powered on, the main control system has confirmed that all the hardware components of all indoor units have received power normally and are in working condition. After ensuring that all the indoor unit hardware is powered on, the main control system will start to check whether the communication connection between each indoor unit and the outdoor unit is normal. The communication may involve data exchange, control signal transmission, etc., to ensure that the main control system of the air conditioner can work in an overall coordinated manner.

[0065] S1022. When there is no communication between any indoor unit and the outdoor unit, and there is still no communication within the preset time period, the operating state of the corresponding indoor unit is the second fault state.

[0066] In step S1022, during the detection process, if it is found that the communication between any indoor unit and the outdoor unit is interrupted or cannot be established, and within a preset period of time (such as 30 seconds, 1 minute, etc.), the above communication fault still exists and cannot be automatically restored in time. In this case, the main control system will determine the operating state of the indoor unit with the communication fault as the second fault state. The second fault state means that although there is no problem with the hardware of the indoor unit, there is a communication fault with the outdoor unit, resulting in the abnormal operation of the main control system of the air conditioner. At this time, the maintenance personnel may need to focus on checking the communication line, diagnosing the communication protocol, or repairing and servicing related equipment.

[0067] In some embodiments, after the step of detecting the communication state between each indoor unit and the outdoor unit, the following steps are further included:

[0068] S10211. When there is communication between any indoor unit and the outdoor unit, detect the device state of the motor.

[0069] In step S10211, if there is communication between any indoor unit and the outdoor unit, it means that the main control system has confirmed that the communication connection between this indoor unit and the corresponding outdoor unit is normal, data and control signals can be effectively transmitted, there is no problem with the hardware of the indoor unit, and there is no problem with the communication between the indoor unit and the outdoor unit. On the basis of no communication fault, the main control system will start to specifically detect the device state of the motor. The device state detection includes, but is not limited to, monitoring multiple parameters such as the voltage, current, speed, temperature, noise, and vibration of the motor to evaluate the operating condition and health of the motor.

[0070] S10212. When the device state of the motor is in an abnormal state, the operating state of the corresponding indoor unit is the third fault state.

[0071] If it is found that the device status of the motor does not meet the preset normal range or standard, for example, the motor has problems such as faults, wear, overheating, excessive vibration, etc., and cannot work properly or has low efficiency. In this case, the main control system will determine the operating status of the indoor unit with the abnormal motor as the third fault status. The third fault status indicates that although the hardware of the indoor unit is normal and the communication between the indoor unit and the outdoor unit is normal, there are problems with the motor part, which may affect the overall performance and lifespan of the air conditioning system.

[0072] S10213. When the device status of the motor is in the normal state, the operating status of the corresponding indoor unit is the healthy state.

[0073] If all the detection indicators of the motor are within the normal range, it indicates that the motor is running well without obvious problems or faults. The main control system determines the operating status of the indoor unit with the normal motor as the healthy state. In the healthy state, all the key components of the indoor unit (including communication and the motor) are in good working condition, and the air conditioning main control system can operate efficiently and stably.

[0074] In some embodiments, after the step of detecting the communication status between each indoor unit and the outdoor unit, it further includes:

[0075] S10214. When there is communication between any indoor unit and the outdoor unit, detect the device status of the float.

[0076] S10215. When the device status of the float is in the abnormal state, the operating status of the corresponding indoor unit is the fourth fault status.

[0077] S10216. When the device status of the float is in the normal state, the operating status of the corresponding indoor unit is the healthy state.

[0078] After confirming the normal communication between the indoor unit and the outdoor unit, the main control system further detects the device status of the float and determines the operating status of the indoor unit according to the detection result:

[0079] In step S10214, if there is communication between any indoor unit and the outdoor unit, at this time, the main control system has confirmed that the communication connection between this indoor unit and the corresponding outdoor unit is normal, and data and control signals can be effectively transmitted. On the basis of no communication fault, the main control system will start to specifically detect the device status of the float. The float is usually used in the air conditioning main control system to monitor and control the level or flow of condensate water. The detection content includes but is not limited to multiple aspects such as the position of the float, its movement, and the accuracy of the sensor signal, etc., to evaluate whether the function of the float is normal.

[0080] In step S10215, if it is found that the device status of the float does not conform to the preset normal range or standard, it indicates that the float may be stuck, displaced, have a sensor failure, a wiring problem, etc., and it is impossible to accurately monitor and control the flow of condensate. At this time, the main control system will determine the operating status of the indoor unit with the abnormal float as the fourth fault status. The fourth fault status indicates that although the communication between the indoor unit and the outdoor unit is normal, there is a problem with the float part, which may affect the drainage function and overall performance of the air conditioner main control system.

[0081] In step S10216, if all the detection indicators of the float are within the normal range, it indicates that the float can work normally and can accurately monitor and control the flow of condensate. In this case, the main control system will determine the operating status of the indoor unit with the normal float as the healthy status. At this time, all the key components of the indoor unit (including communication, motor, and float) are in good working condition, and the air conditioner main control system can operate efficiently, stably, and safely, avoiding potential failures or damages caused by condensate problems.

[0082] In some embodiments, the step of controlling the prompting component of the corresponding indoor unit to emit a warning signal specifically includes:

[0083] S111. Control the prompting component of the corresponding indoor unit to emit a warning signal adapted to the type of fault status.

[0084] When the main control system detects that the operating status of a certain indoor unit is the fault status, the main control system will start the control process of the prompting component of the indoor unit. The prompting component generally includes but is not limited to warning lights, buzzers, display screens, etc., and is used to provide visual, auditory, or other forms of warning information to users or maintenance personnel. In the process of controlling the prompting component, the main control system will decide what kind of warning signal to emit according to the specific type of the fault status. Different fault statuses require different countermeasures. By emitting specific warning signals, the type and severity of the fault can be conveyed more accurately.

[0085] The specific steps include the following points:

[0086] (1) Determine the type of fault status: The main control system first needs to clarify which type the current fault status of the indoor unit belongs to, such as the first fault status (hardware not powered on), the second fault status (communication fault), the third fault status (motor abnormality), or the fourth fault status (float abnormality), etc.

[0087] (2) Programming or configuring warning signals: For each type of fault status, the main control system has pre-set corresponding warning signals in advance. The warning signals may include the flashing pattern of warning lights of specific colors (e.g., red represents a serious fault, and yellow represents a minor fault), the tone and frequency of the buzzer (e.g., continuous rapid beeping indicates an emergency, and intermittent slow beeping indicates a non-emergency problem), error codes or text descriptions on the display screen, etc.

[0088] (3) Activating warning signals: Once the warning signal suitable for the fault status type is determined, the main control system will send an instruction to the prompt component of the corresponding indoor unit to make it start emitting the pre-set warning signal.

[0089] Through the above steps, maintenance personnel or users can directly determine the fault type of the indoor unit according to the type of warning signal, which helps to quickly locate and repair, improving the maintenance efficiency.

[0090] In some embodiments, after the step of responding to receiving the fault signal, it further includes:

[0091] S120. Detect the current condition of the outdoor unit and determine the operating state of the outdoor unit according to the current condition of the outdoor unit.

[0092] S130. When the operating state of the outdoor unit is a fault state, control the prompt components of at least one indoor unit to emit warning signals.

[0093] In steps S120 to S130, after receiving the fault signal, the main control system will also start the detection process of the current condition of the outdoor unit. The detection process includes checking various parameters and states of the outdoor unit, such as power supply, compressor operating state, fan speed, temperature sensor readings, pressure sensor readings, etc. Based on the detection results of each item of the outdoor unit, the main control system will analyze and determine the operating state of the outdoor unit; the operating state includes a healthy state, a fault state, or other specific abnormal states. For example, if the compressor of the outdoor unit does not work, the power supply is unstable, or the temperature sensor reading is abnormal, then the operating state of the outdoor unit may be judged as a fault state.

[0094] If the main control system determines that the operating state of the outdoor unit is a fault state, it means that there are problems with the outdoor unit that affect the performance or safety of the overall air conditioner main control system. At this time, the main control system will take actions to control the prompt components of at least one (or all) indoor units to emit warning signals. The warning signals are intended to notify users or maintenance personnel that there is a fault with the outdoor unit and that it needs to be inspected and repaired. The warning signals may include the flashing of warning lights on the indoor unit, buzzer alarms, error codes or messages displayed on the display screen, etc. It should be noted that the warning signals used to indicate a fault with the outdoor unit are different from the warning signals for indoor unit faults, which helps maintenance personnel quickly locate the fault state of the outdoor unit.

[0095] For the fault troubleshooting device of a multi-connected air conditioner according to the second aspect embodiment of the present invention, please refer to Figure 2 , including:

[0096] A detection module 201, configured to sequentially detect the current status of each indoor unit in response to receiving a fault signal, and determine the operating status of the corresponding indoor unit according to the current status of each indoor unit; wherein, the operating status includes a healthy status and at least one fault status.

[0097] A control module 202, configured to control the prompt component of the corresponding indoor unit to emit a warning signal when the operating status of any indoor unit is a fault status.
