[0002] At present, the centralized control technology of multi-split air conditioners in buildings is becoming more and more mature. With the continuous development of air conditioning technology, large buildings, factories, shopping malls and other places have an increasing demand for centralized control of multi-split air conditioning systems. When the building is powered on again after an unexpected power outage, the multi-split air conditioning system needs to be restarted, but the simultaneous startup of a large number of units will cause a large current impact on the power supply in a short period of time, posing a safety hazard.

[0003] In the prior art, a pre-start time can be set for each air-conditioning outdoor unit in a building multi-split air-conditioning system, and bound to the IP address of the air-conditioning outdoor unit, so that each air-conditioner can be started according to the pre-start time.

[0004] However, since this method requires the startup time to be set in advance and has a low degree of intelligence, the operation is more complicated, and the setting is prone to errors, which is not conducive to installation and debugging. Summary of the invention

[0011] The startup sequence is used to sequentially control the startup of each of the to-be-started outdoor units, so that the to-be-started outdoor unit controls the startup of the connected to-be-started indoor unit.

[0012] In the air conditioning control method provided in the embodiment of the present application, the centralized control device can determine the to-be-started outdoor units and the to-be-started indoor units from the multiple air conditioning outdoor units and the multiple air conditioning indoor units according to the standby parameters, pre-power-off state parameters and component state parameters corresponding to each air conditioning outdoor unit and each air conditioning indoor unit when the multi-split air conditioning system is powered on, and then the priority scores of each to-be-started outdoor unit can be calculated according to the attribute parameters and operation parameters of each to-be-started outdoor unit, and the start-up order of each to-be-started outdoor unit can be determined according to the priority scores of each to-be-started outdoor unit, so as to control the start-up and operation of each to-be-started outdoor unit in sequence according to the start-up order, and then the to-be-started outdoor unit controls the start-up and operation of each standby indoor unit connected to it. In this way, there is no need to set the start-up time in advance, and the centralized control device sets the start-up order for each air conditioning outdoor unit according to the actual situation of the multi-split air conditioning system, so as to start them in sequence, which can not only avoid the impact of a large number of units starting at the same time on the power supply and improve the start-up safety, but also improve the degree of intelligence, simplify the operation, reduce the difficulty of setting, and facilitate installation and debugging.

[0013] In an optional embodiment, the component state parameters include external unit component state parameters corresponding to each external unit component of the air conditioner outdoor unit, and internal unit component state parameters corresponding to each internal unit component of the air conditioner indoor unit;

[0015] For each of the air-conditioning outdoor units, if the standby parameter corresponding to the air-conditioning outdoor unit indicates that the air-conditioning outdoor unit is in a normal standby state and the state parameter before power failure indicates that the air-conditioning outdoor unit is in a normal operating state before power failure, then determine whether each of the outdoor components of the air-conditioning outdoor unit has a component failure according to the state parameter of the outdoor component of the air-conditioning outdoor unit;

[0019] The air-conditioning control method provided in the embodiment of the present application can first determine whether the current standby states of the air-conditioning outdoor unit and the air-conditioning indoor unit are normal and whether the operating states before power failure are normal based on the standby parameters and the state parameters before power failure. If both are normal, it is determined whether there is a component failure in the air-conditioning outdoor unit and the air-conditioning indoor unit through the component state parameters, thereby determining the outdoor unit to be started and the indoor unit to be started. Therefore, fault analysis can be performed in time when the multi-split air-conditioning system is restarted to ensure that the outdoor unit to be started and the indoor unit to be started can be started smoothly, so that the entire startup process remains smooth and trouble-free, thereby improving the startup efficiency.

Therefore, the component fault in the air-conditioning outdoor unit can be pre-eliminated during the restart process to ensure that the outdoor unit to be started can be started smoothly, thereby improving the startup efficiency. At the same time, the fault that cannot be handled can be promptly notified to the staff through alarm information, so that the fault can be handled in time.

[0028] For each of the air conditioner indoor units, determining whether an indoor unit component parameter corresponding to the indoor unit component exceeds a second parameter threshold value corresponding to the indoor unit component;

[0029] If the internal machine component parameter corresponding to the internal machine component does not exceed the second parameter threshold corresponding to the internal machine component, it is determined that there is no component failure in the internal machine component;

[0030] If the internal machine component parameter corresponding to the internal machine component exceeds the second parameter threshold corresponding to the internal machine component, performing fault processing on the internal machine component according to a pre-stored fault processing logic;

[0031] reacquiring the current internal machine component parameter of the internal machine component, and determining whether the internal machine component parameter exceeds the second parameter threshold, until the internal machine component parameter does not exceed the second parameter threshold, or the corresponding fault judgment number of the internal machine component reaches a second preset number;

[0032] If the number of fault judgments corresponding to the indoor component reaches the second preset number, it is determined that there is a component fault in the indoor component and an alarm message is issued.

[0033] The air-conditioning control method provided in the embodiment of the present application is that the centralized control device can, for each indoor unit of the air-conditioning, perform fault processing on the indoor unit component according to the pre-stored fault processing logic when the indoor unit component parameter exceeds the second parameter threshold value corresponding to the indoor unit component. Therefore, the component fault in the indoor unit of the air-conditioning can be pre-eliminated during the restart process to ensure that the indoor unit to be started can be started smoothly, thereby improving the startup efficiency. At the same time, the fault that cannot be handled can be promptly notified to the staff through alarm information, so that the fault can be handled in time.

[0034] In an optional embodiment, the multi-split air conditioning system includes a plurality of air conditioning groups, each of which includes a plurality of air conditioning outdoor units and air conditioning indoor units connected to the air conditioning outdoor units;

[0037] The step of determining the start-up order of each of the to-be-started external units according to the priority scores of each of the to-be-started external units comprises:

[0038] For each of the air-conditioning groups, determining a start-up order of each of the outdoor units to be started according to the priority scores of each of the outdoor units to be started in the air-conditioning group;

[0039] The step of sequentially controlling the startup of each of the external units to be started according to the startup sequence comprises:

[0040] The target air-conditioning group to be started is determined according to the control sequence of each of the air-conditioning groups, and each of the outdoor units to be started is controlled to start and operate in sequence according to the start sequence of each of the outdoor units to be started in the target air-conditioning group.

[0041] The air conditioning control method provided in the embodiment of the present application can group multiple air conditioning outdoor units and air conditioning indoor units, and process each air conditioning outdoor unit and air conditioning indoor unit in each air conditioning group respectively, so as to sort the air conditioning groups, and sort each of the outdoor units to be started in each air conditioning group. When starting and running, the target air conditioning group to be controlled can be determined in sequence, and each of the outdoor units to be started can be controlled in sequence according to the starting order. In this way, it is convenient for the centralized control device to control the outdoor units to be started in sequence.

[0042] In an optional implementation manner, the step of sequentially controlling the startup of each of the external units to be started according to the startup sequence includes:

[0043] According to the start-up sequence corresponding to each of the outdoor units to be started and the preset delay time, each of the outdoor units to be started is controlled to start in sequence.

[0044] In the air conditioning control method provided in the embodiment of the present application, the centralized control device can control the startup of each outdoor unit to be started in combination with the startup sequence corresponding to each outdoor unit to be started and the preset delay time, thereby simplifying the startup control process.

[0045] In an optional embodiment, the method further comprises:

[0046] Under the condition that each of the to-be-started external machines is controlled to start and run in sequence according to the start-up sequence, the grid load parameters and the state parameters of each target to-be-started external machine that has not started and run are obtained in real time;

[0047] If the grid load parameter indicates that the grid load exceeds the preset load, then stop controlling the start-up operation of each of the target external machines to be started;

[0048] If the state parameter of the target outdoor unit to be started indicates that the target outdoor unit to be started has a fault, the target outdoor unit to be started is skipped.

[0049] The air-conditioning control method provided in the embodiment of the present application is a centralized control device that can monitor the grid load situation and the status of the unstarted external units to be started in real time while controlling the start-up and operation of each external unit to be started in sequence, thereby dynamically adjusting the current control logic based on the actual situation. It is therefore more adaptable to actual application conditions, ensuring that the grid load does not exceed the preset load, and that the external units to be started can be started smoothly.

[0050] In a second aspect, the present application provides an air conditioning control device, which is applied to a centralized control device, wherein the centralized control device is communicatively connected to a multi-split air conditioning system, wherein the multi-split air conditioning system includes a plurality of air conditioning outdoor units and a plurality of air conditioning indoor units, and each of the air conditioning outdoor units is connected to a plurality of the air conditioning indoor units, wherein the device includes:

[0053] The determination module is further used to calculate the priority scores corresponding to the external units to be started according to the attribute parameters and operation parameters of the external units to be started, and determine the start order of the external units to be started according to the priority scores of the external units to be started;

[0054] The control module is used to control the startup and operation of each of the to-be-started outdoor units in sequence according to the startup sequence, so that the to-be-started outdoor unit controls the startup and operation of the connected to-be-started indoor unit.

[0055] The air conditioning control method provided in the embodiment of the present application, through the acquisition module, when the multi-split air conditioning system is powered on, respectively acquires the standby parameters, pre-power-off state parameters and component state parameters corresponding to each air-conditioning outdoor unit and each air-conditioning indoor unit; through the determination module, according to the standby parameters, pre-power-off state parameters and component state parameters, the to-be-started outdoor unit and the to-be-started indoor unit are determined from multiple air-conditioning outdoor units and multiple air-conditioning indoor units, and the priority scores corresponding to each to-be-started outdoor unit are calculated according to the attribute parameters and operation parameters of each to-be-started outdoor unit, and the start-up order of each to-be-started outdoor unit is determined according to the priority scores of each to-be-started outdoor unit; through the control module, each to-be-started outdoor unit is controlled to start and run in sequence according to the start-up order, so that the to-be-started outdoor unit controls the connected to-be-started indoor unit to start and run. In this way, there is no need to set the start-up time in advance, and the centralized control device sets the start-up order for each air-conditioning outdoor unit according to the actual situation of the multi-split air conditioning system, so that they are started in sequence, which can not only avoid the impact of a large number of units starting at the same time on the power supply, improve the start-up safety, but also improve the degree of intelligence, simplify the operation, reduce the difficulty of setting, and facilitate installation and debugging.

[0064] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0065] Figure 1 For a block diagram of the centralized control system, see Figure 1 The centralized control system includes a centralized control device 10 and a multi-split air conditioning system 20, and the centralized control device 10 is communicatively connected with the multi-split air conditioning system 20.

[0066] Optionally, the multi-split air conditioning system 20 includes a plurality of air-conditioning outdoor units 200 and a plurality of air-conditioning indoor units 210 , and each air-conditioning outdoor unit 200 is connected to a plurality of air-conditioning indoor units 210 .

[0067] It can be understood that the centralized control device can be communicatively connected with both the air conditioner outdoor unit and the air conditioner indoor unit.

[0068] Optionally, a centralized control management system may also be provided in the centralized control device 10 for centralized control of the multi-split air-conditioning system.

[0069] Optionally, in Figure 1 On the basis of Figure 2 For a block diagram of the centralized control device 10 provided in the embodiment of the present application, please refer to Figure 2 The centralized control device 10 includes a memory 100, a processor 110, and a communication module 120. The memory 100, the processor 110, and the communication module 120 are electrically connected to each other directly or indirectly to achieve data transmission or interaction. For example, these components can be electrically connected to each other through one or more communication buses or signal lines.

[0070] The memory 100 is used to store computer programs or data that can be executed by the processor. The memory 100 can be, but is not limited to, a random access memory (RAM), a read only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable read-only memory (EEPROM), etc.

[0071] The processor 110 is used to read / write data or computer programs stored in the memory, and execute the computer program to implement the air conditioning control method provided in the embodiment of the present application.

[0072] The communication module 120 is used to establish a communication connection between the centralized control device and other communication terminals through the network, and to send and receive data through the network.

[0073] It should be understood that Figure 2 The structure shown is only a schematic diagram of the structure of the centralized control device. The centralized control device may also include Figure 2 More or fewer components as shown, or with Figure 2 Different configurations shown. Figure 2 Each component shown in the figure can be implemented by hardware, software or a combination thereof.

[0074] Next, Figure 1 The centralized control device is the execution body, and the air conditioning control method provided in the embodiment of the present application is exemplarily introduced in combination with the flow chart.

[0075] Specifically, Figure 3 A flow chart of the air conditioning control method provided in the embodiment of the present application is shown in FIG. Figure 3 , the method comprising:

[0076] Step S20, when the multi-split air conditioning system is powered on, respectively obtain the standby parameters, pre-power-off state parameters and component state parameters corresponding to each air-conditioning outdoor unit and each air-conditioning indoor unit.

[0077] Optionally, the centralized control device may obtain the standby parameters, pre-power-off status parameters, and component status parameters corresponding to each air-conditioning outdoor unit and each air-conditioning indoor unit when the multi-split air-conditioning system is powered on again after being powered off.

[0078] Optionally, the centralized control device has a power-off recording function. When a power-off event of the multi-split air-conditioning system is detected, the centralized control device can record the status parameters of each air-conditioning outdoor unit and each air-conditioning indoor unit.

[0079] Optionally, the component state parameter refers to the state parameter corresponding to each component in the air conditioner outdoor unit and the air conditioner indoor unit. In this embodiment, the component state parameter may also include the environmental state of each component, such as the environmental temperature.

[0080] Step S21, determining an outdoor unit to be started and an indoor unit to be started from a plurality of air-conditioning outdoor units and a plurality of air-conditioning indoor units according to the standby parameters, the state parameters before power failure and the component state parameters.

[0081] Step S22, calculating the priority scores corresponding to the outdoor units to be started according to the attribute parameters and operation parameters of the outdoor units to be started, and determining the start order of the outdoor units to be started according to the priority scores of the outdoor units to be started.

[0082] Optionally, the attribute parameters may include the power of the outdoor unit to be started, the air conditioning demand of the working area, etc.

[0083] Optionally, the air conditioning demand situation in the working area refers to whether the area where the outdoor unit to be started is located has a greater demand for air conditioning. For example, the demand for air conditioning in an underground garage may be smaller, while the demand for air conditioning in an office may be greater.

[0084] In this embodiment, the centralized control device can score the outdoor unit to be started according to the power of the outdoor unit to be started, the air conditioning demand of the working area and other attribute parameters to obtain a first score. It can be understood that the first score is a fixed score of the outdoor unit to be started, and the centralized control device can store it and directly obtain it when it needs to calculate the priority score later.

[0085] Optionally, the operating parameter refers to some dynamic evaluation parameters of the external unit to be started, such as the number of failures and service life of the external unit to be started. The centralized control device can score the external unit to be started according to these parameters, obtain a second score, and calculate the priority score based on the first score and the second score.

[0086] In one possible implementation, the priority score may be the sum of the first score and the second score.

[0087] It can be understood that the higher the priority score is, the earlier the startup order of the outdoor unit to be started is.

[0088] In this embodiment, since the priority score takes into account fixed attribute parameters such as the overall power and location of the outdoor unit to be started, and dynamic operating parameters such as the number of failures and service life, the priority of the outdoor unit to be started can be determined according to the actual situation of the outdoor unit to be started to achieve the corresponding optimization goal. For example, the outdoor unit to be started with smaller power can be started first, and then the outdoor unit to be started with larger power; the outdoor unit to be started in the area with greater demand for air conditioning can be started first, and then the outdoor unit to be started in the area with less demand for air conditioning, and so on.

[0089] Optionally, since each air-conditioning outdoor unit is connected to fewer air-conditioning indoor units and the overall power of the outdoor units to be started is taken into account when considering the sorting, it is not necessary to sort the indoor units to be started connected to each air-conditioning outdoor unit.

[0090] Step S23, controlling the startup of each of the outdoor units to be started in sequence according to the startup sequence, so that the outdoor unit to be started controls the startup of the connected indoor unit to be started.

[0091] Optionally, in order to facilitate accurate identification and control of each outdoor unit, the overall network architecture of the multi-split air-conditioning system may also be stored in the centralized control device. For example, the indoor air-conditioning unit in which room in which area can be controlled by the outdoor air-conditioning unit in which area. Therefore, the centralized control device can accurately control the startup and operation of each outdoor unit to be started in sequence.

[0092] Optionally, the centralized control device may also send information of the indoor unit to be started corresponding to the outdoor unit to be started to the outdoor unit to be started, and the outdoor unit to be started may control the corresponding indoor unit to be started to start and run after being started.

[0093] It can be understood that this method can also reduce the maintenance cost of air conditioning information. For example, if some information of an air conditioner outdoor unit or an air conditioner indoor unit needs to be modified, there is no need to modify the configuration on a large scale. You only need to update the relevant information in the overall network architecture.

[0094] In the air conditioning control method provided in the embodiment of the present application, the centralized control device can determine the to-be-started outdoor units and the to-be-started indoor units from the multiple air conditioning outdoor units and the multiple air conditioning indoor units according to the standby parameters, pre-power-off state parameters and component state parameters corresponding to each air conditioning outdoor unit and each air conditioning indoor unit when the multi-split air conditioning system is powered on, and then the priority scores of each to-be-started outdoor unit can be calculated according to the attribute parameters and operation parameters of each to-be-started outdoor unit, and the start-up order of each to-be-started outdoor unit can be determined according to the priority scores of each to-be-started outdoor unit, so as to control the start-up and operation of each to-be-started outdoor unit in sequence according to the start-up order, and then the to-be-started outdoor unit controls the start-up and operation of each standby indoor unit connected to it. In this way, there is no need to set the start-up time in advance, and the centralized control device sets the start-up order for each air conditioning outdoor unit according to the actual situation of the multi-split air conditioning system, so as to start them in sequence, which can not only avoid the impact of a large number of units starting at the same time on the power supply and improve the start-up safety, but also improve the degree of intelligence, simplify the operation, reduce the difficulty of setting, and facilitate installation and debugging.

[0095] Optionally, considering that the multi-split air-conditioning system in the building includes a large number of outdoor air-conditioning units and indoor air-conditioning units, in order to facilitate control, the multiple outdoor air-conditioning units and indoor air-conditioning units can be divided into multiple air-conditioning groups, and each air-conditioning group can be analyzed and controlled separately.

[0096] Specifically, the multi-split air conditioning system may include a plurality of air conditioning groups, each of which includes a plurality of air conditioning outdoor units and air conditioning indoor units connected to the air conditioning outdoor units.

[0097] In one possible implementation, in order to facilitate centralized control, multiple air conditioner outdoor units and air conditioner indoor units with similar settings can be divided into an air conditioner group. For example, all air conditioner outdoor units and air conditioner indoor units in an entire building can be grouped as one air conditioner group.

[0098] In this embodiment, when the multi-split air-conditioning system is powered on, the centralized control device can obtain the standby parameters, pre-power-off status parameters and component status parameters corresponding to each air-conditioning outdoor unit and each air-conditioning indoor unit in each air-conditioning group.

[0099] In this embodiment, the centralized control device can determine the outdoor units to be started and the indoor units to be started from multiple air-conditioning outdoor units and multiple air-conditioning indoor units for each air-conditioning group respectively according to the standby parameters, pre-power-off state parameters and component state parameters corresponding to each air-conditioning outdoor unit and each air-conditioning indoor unit in the air-conditioning group, and determine the control order of each air-conditioning group according to the determination order of all the outdoor units to be started and the indoor units to be started in each air-conditioning group.

[0100] Optionally, considering that the outdoor units to be started and the indoor units to be started in some air-conditioning groups are determined faster and the outdoor units to be started and the indoor units to be started in some air-conditioning groups are determined slower, the centralized control device can sort and control the outdoor units to be started first for the air-conditioning groups that have first determined all the outdoor units to be started and the indoor units to be started.

[0101] That is to say, if all the outdoor units and indoor units to be started included in a certain air-conditioning group are first determined, the centralized control device can set its control order as 1, and then sort the air-conditioning groups in sequence according to the determined order.

[0102] In this embodiment, the centralized control device can determine the starting order of each outdoor unit to be started for each air-conditioning group according to the priority scores of each outdoor unit to be started in the air-conditioning group, and then determine the target air-conditioning group to be started according to the control order of each air-conditioning group, and control the start-up and operation of each outdoor unit to be started in sequence according to the starting order of each outdoor unit to be started in the target air-conditioning group.

[0103] Optionally, the centralized control device may sort the outdoor units to be started in each air-conditioning group respectively, and then determine the target air-conditioning group to be started according to the control order of the air-conditioning group. For example, the air-conditioning group with a control order of 1 is first determined as the target air-conditioning group, and the outdoor units to be started therein are started in sequence according to their corresponding start-up order, and then the air-conditioning group with a control order of 2 is determined as the target air-conditioning group, and the outdoor units to be started therein are started in sequence according to their corresponding start-up order, and so on.

[0104] Optionally, in order to ensure that both the air conditioner outdoor unit and the air conditioner indoor unit can be started smoothly, they can be screened, and the air conditioner outdoor unit and the air conditioner indoor unit that are in normal status and have no component failure are determined as the outdoor unit to be started and the indoor unit to be started.

[0105] In this embodiment, the component state parameters may include external component state parameters corresponding to each external component of the air conditioner outdoor unit and internal component state parameters corresponding to each internal component of the air conditioner indoor unit.

[0106] Next, a possible implementation method is provided for determining the outdoor unit to be started and the indoor unit to be started from multiple air-conditioning outdoor units and multiple air-conditioning indoor units according to the standby parameters, the state parameters before power failure and the component state parameters.

[0107] Specifically, for each air-conditioning outdoor unit, if the standby parameter corresponding to the air-conditioning outdoor unit indicates that the air-conditioning outdoor unit is in a normal standby state and the state parameter before power failure indicates that the air-conditioning outdoor unit is in a normal operating state before power failure, then it is determined whether there is a component failure in each external unit component of the air-conditioning outdoor unit according to the external unit component state parameters of the air-conditioning outdoor unit.

[0108] It can be understood that if none of the outdoor unit components of the air-conditioning outdoor unit has component failure, the air-conditioning outdoor unit is determined to be an outdoor unit to be started.

[0109] Optionally, the centralized control device can determine whether each air-conditioning outdoor unit is in a normal standby state according to its corresponding standby parameters. If it is in a normal standby state, it can determine whether the air-conditioning outdoor unit is in a normal operating state before power failure according to the state parameters before power failure.

[0110] Optionally, the state parameters before power failure may include compressor operating parameters, temperature setting values, wind speed, etc.

[0111] Optionally, if the air-conditioning outdoor unit is in a normal operating state before power failure, component failure detection may be performed on the air-conditioning outdoor unit.

[0112] In addition, for each air-conditioning indoor unit, if the standby parameter corresponding to the air-conditioning indoor unit indicates that the air-conditioning indoor unit is in a normal standby state and the state parameter before power failure indicates that the air-conditioning indoor unit is in a normal operating state before power failure, then it is determined whether there is a component failure in each indoor component of the air-conditioning indoor unit according to the indoor component state parameters of the air-conditioning indoor unit.

[0113] It can be understood that if there is no component failure in each indoor unit of the air conditioner indoor unit, it is determined that the indoor unit of the air conditioner is an indoor unit to be started.

[0114] Optionally, the centralized control device can determine whether each air-conditioning indoor unit is in a normal standby state according to its corresponding standby parameters. If it is in a normal standby state, it can determine whether the air-conditioning indoor unit is in a normal operating state before power failure according to the state parameters before power failure.

[0115] Optionally, the state parameters before power failure may include cooling and heating state, temperature setting value, wind speed, etc. Optionally, if the air conditioner outdoor unit is in a normal operating state before power failure, component failure detection may be performed on the air conditioner outdoor unit.

[0116] Next, a possible implementation method is provided for determining whether each external unit component of the air conditioner outdoor unit has a component failure according to the external unit component status parameters of the air conditioner outdoor unit.

[0117] Specifically, the centralized control device may determine, for each air-conditioning outdoor unit, whether an outdoor unit component parameter corresponding to the outdoor unit component exceeds a first parameter threshold corresponding to the outdoor unit component.

[0118] In this embodiment, if the external unit component parameter corresponding to the external unit component does not exceed the first parameter threshold corresponding to the external unit component, the centralized control device can determine that there is no component failure in the external unit component; if the external unit component parameter corresponding to the external unit component exceeds the first parameter threshold corresponding to the external unit component, the centralized control device can perform fault handling on the external unit component according to the pre-stored fault handling logic.

[0119] Optionally, the centralized control device stores a first parameter threshold corresponding to each external unit component. The first parameter threshold is a default value when the air-conditioning outdoor unit is powered on and used for the first time. Thereafter, the air-conditioning outdoor unit can update the default value according to the historical application data of each external unit component to make the first parameter threshold more suitable for the actual application of the air-conditioning outdoor unit.

[0120] Optionally, if the parameter of the external component exceeds the first parameter threshold, there may be a fault, so the centralized control device can process the external component according to the pre-stored fault processing logic. For example, if the temperature of the controller is too high, the operating speed of the cooling fan can be increased to dissipate heat from the controller until the temperature of the controller drops to the operating temperature. Optionally, the centralized control device can re-acquire the current external component parameter of the external component and determine whether the external component parameter exceeds the first parameter threshold until the external component parameter does not exceed the first parameter threshold, or the corresponding fault judgment number of the external component reaches a first preset number of times.

[0121] Optionally, after processing the external component, the centralized control device may reacquire current external component parameters of the external component, and determine whether there is a component failure in the external component according to the external component parameters.

[0122] Optionally, considering that there are many components in the air conditioner outdoor unit, there may be a problem of repeatedly obtaining the same parameter and making judgments at the same time. Therefore, in order to avoid unnecessary loops or repeated operations, the centralized control device can also determine whether the parameters of the outdoor unit components are repeated when it is determined that there is no component failure in the outdoor unit components.

[0123] It can be understood that if the external unit component parameters are repeated, other repeated external unit component parameters can be deleted to prevent invalid judgment.

[0124] Optionally, considering that there may be a problem that the fault cannot be solved, the centralized control device can also determine whether the number of times the external unit component repeats the fault judgment reaches a first preset number of times. Optionally, the first preset number of times can be set according to the actual application situation. In a possible implementation method, the first preset number of times can be 3 times.

[0125] Optionally, if the number of fault judgments corresponding to the external component reaches a first preset number, the centralized control device may determine that a component fault exists in the external component and issue an alarm message.

[0126] It is understandable that if the number of fault judgments reaches the first preset number, it means that the fault problem cannot be solved by the pre-stored fault processing logic, so an alarm message can be issued to allow staff to maintain the fault.

[0127] In addition, if the corresponding fault handling logic cannot be matched, an alarm message can also be issued so that the staff can maintain the fault.

[0128] In this embodiment, if the outdoor unit has a component fault that cannot be resolved by the pre-stored fault processing logic, it cannot be started, so the air conditioner outdoor unit will not be used as an outdoor unit to be started.

[0129] Next, a possible implementation method is provided for determining whether there is a component failure in each internal component of the air conditioner according to the status parameters of the internal components of the air conditioner.

[0130] Specifically, the centralized control device may determine, for each indoor unit of the air conditioner, whether the indoor unit component parameter corresponding to the indoor unit component exceeds the second parameter threshold corresponding to the indoor unit component.

[0131] In this embodiment, if the internal machine component parameter corresponding to the internal machine component does not exceed the first parameter threshold corresponding to the internal machine component, the centralized control device can determine that there is no component failure in the internal machine component. If the internal machine component parameter corresponding to the internal machine component exceeds the second parameter threshold corresponding to the internal machine component, the centralized control device can perform fault processing on the internal machine component according to the pre-stored fault processing logic.

[0132] Optionally, the centralized control device stores a second parameter threshold corresponding to each indoor component. The second parameter threshold is a default value when the air conditioner indoor unit is powered on and used for the first time. Thereafter, the air conditioner indoor unit can update the default value according to the historical application data of each indoor component to make the first parameter threshold more suitable for the actual application of the air conditioner indoor unit.

[0133] Optionally, if the parameter of the indoor component exceeds the second parameter threshold, there may be a fault, so the centralized control device can process the indoor component according to a pre-stored fault processing logic.

[0134] Optionally, the centralized control device may re-acquire the current internal machine component parameters of the internal machine component to determine whether the internal machine component parameters exceed the second parameter threshold, until the internal machine component parameters do not exceed the second parameter threshold, or the corresponding fault judgment times of the internal machine component reach a second preset number of times.

[0135] Optionally, after processing the indoor component, the centralized control device may reacquire current indoor component parameters of the indoor component, and determine whether the indoor component has a component failure according to the indoor component parameters.

[0136] Optionally, considering that there are many components in the indoor unit of the air conditioner, there may be a problem of repeatedly obtaining the same parameter and making judgments at the same time. Therefore, in order to avoid unnecessary loops or repeated operations, the centralized control device can also determine whether the parameters of the indoor unit components are repeated when it is determined that there is no component failure in the indoor unit components.

[0137] It can be understood that if the internal machine component parameters are repeated, other repeated internal machine component parameters can be deleted to prevent invalid judgment.

[0138] Optionally, considering that there may be a problem that cannot be solved, the centralized control device can also determine whether the number of times the internal machine component repeats the fault judgment reaches a second preset number.

[0139] Optionally, the second preset number of times can be set according to actual application conditions. In a possible implementation, the second preset number of times can be consistent with the first preset number of times, for example, 3 times.

[0140] Optionally, if the number of fault judgments corresponding to the indoor component reaches a second preset number, the centralized control device may determine that there is a component failure in the indoor component and issue an alarm message.

[0141] It is understandable that if the number of fault judgments reaches the second preset number, it means that the fault problem cannot be solved by the pre-stored fault processing logic, so an alarm message can be issued to allow staff to maintain the fault.

[0142] In addition, if the corresponding fault handling logic cannot be matched, an alarm message can also be issued so that the staff can maintain the fault.

[0143] In this embodiment, if the indoor unit has a component fault that cannot be resolved by the pre-stored fault processing logic, it cannot be started, so the air conditioner indoor unit will not be used as an indoor unit to be started.

[0144] Optionally, considering that if the air-conditioning outdoor unit is not the to-be-started outdoor unit, the air-conditioning indoor unit connected thereto cannot be turned on normally, it is not necessary to set the air-conditioning indoor units corresponding to these air-conditioning outdoor units as the to-be-started indoor units.

[0145] Similarly, if all the air-conditioning indoor units connected to a certain air-conditioning outdoor unit are not the indoor units to be started, then even if the air-conditioning outdoor unit is the outdoor unit to be started, it does not need to be started, so there is no need to set the air-conditioning outdoor unit as the outdoor unit to be started.

[0146] In a possible implementation, the centralized control device may also store a delay time, and the centralized control device may sequentially control the startup of each of the outdoor units to be started according to the startup sequence corresponding to each of the outdoor units to be started and the preset delay time.

[0147] Optionally, the centralized control device may control the startup of each external machine to be started by sending a delay instruction to each external machine to be started. The delay instruction may include a delay time, indicating that the external machine to be started may wait for the delay time before starting after receiving the instruction.

[0148] In one example, if the startup order of a certain external machine to be started is n and the delay time is T, the centralized control device may send a delay instruction to the external machine to be started, instructing the external machine to be started to delay for nT before starting.

[0149] Optionally, taking into account that during the actual startup process there may be a large grid load and / or a fault in the external unit to be started, during the actual startup process, the centralized control device may also monitor the grid load condition and the equipment condition of the external unit to be started.

[0150] Specifically, the centralized control device can obtain the grid load parameters and the status parameters of each target external machine to be started that has not started running in real time while controlling the start-up and operation of each external machine to be started in sequence.

[0151] In this embodiment, if the grid load parameter indicates that the grid load exceeds the preset load, the control of starting and running of each target external machine to be started is stopped; if the status parameter of the target external machine to be started indicates that there is a fault in the target external machine to be started, the target external machine to be started is skipped.

[0152] Optionally, if the grid load exceeds the preset load, the centralized control device may no longer start the external unit to be started that has not yet been started. If a target external unit to be started suddenly fails, the centralized control device may skip the target external unit to be started and not start it, but instead start the next external unit to be started after the target external unit to be started.

[0153] It can be understood that through this method, the startup process of the multi-split air-conditioning system can be more adaptable to changes in actual conditions, while at the same time keeping the entire startup process smooth and trouble-free, thereby improving startup efficiency.

[0166] Optionally, the determination module 310 is also used to determine the outdoor units to be started and the indoor units to be started from multiple air-conditioning outdoor units and multiple air-conditioning indoor units for each air-conditioning group respectively according to the standby parameters, pre-power-off state parameters and component state parameters corresponding to each air-conditioning outdoor unit and each air-conditioning indoor unit in the air-conditioning group, and determine the startup sequence control sequence of each air-conditioning group according to the determination order of all the outdoor units to be started and the indoor units to be started in each air-conditioning group.

[0167] Optionally, the determination module 310 is further configured to determine, for each air-conditioning group, a start-up order of each outdoor unit to be started according to a priority score of each outdoor unit to be started in the air-conditioning group.
