[0072] The communication module 120 is configured to establish a communication connection between the central control device and other communication terminals via a network, and configured to transmit and receive data via the network.

[0073] It should be understood that, Figure 2 The structure shown is only a structural schematic diagram of the central control device, and the central control device can further include more or less components than those shown in Figure 2 or have a different configuration from that shown in Figure 2 . Figure 2 The components shown in the foregoing embodiments can be implemented in hardware, software, or a combination thereof.

[0074] Next, the central control device in Figure 1 will be taken as an execution subject, and the air conditioner control method provided by the embodiments of the present application will be exemplarily introduced in combination with a flowchart.

[0075] Specifically, Figure 3 a flowchart of the air conditioner control method provided by the embodiments of the present application, please refer to Figure 3 , which comprises the following steps.

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

[0077] Optionally, the central control device can acquire the standby parameters, pre-power-off state parameters and component state parameters corresponding to each air conditioner outdoor unit and each air conditioner indoor unit in the case that the multi-split air conditioning system is powered on again after power-off.

[0078] Optionally, the central control device has a power-off record function, and when detecting a power-off event of the multi-split air conditioning system, the central control device can record the state parameters of each air conditioner outdoor unit and each air conditioner 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 the present embodiment, the component state parameter can further include the environmental state of each component, such as the environmental temperature, etc.

[0080] Step S21, according to the standby parameters, pre-power-off state parameters and component state parameters, the standby outdoor units and the standby indoor units are determined from the plurality of air conditioner outdoor units and the plurality of air conditioner indoor units.

[0081] Step S22, the priority scores corresponding to each standby outdoor unit are calculated according to the attribute parameters and the operating parameters of each standby outdoor unit, and the startup order of each standby outdoor unit is determined according to the priority scores of each standby outdoor unit.

[0082] Optionally, the attribute parameter can include a power size of the to-be-started outdoor unit, an air conditioner demand situation of a working area, etc.

[0083] Optionally, the air conditioner demand situation of the working area refers to whether the area where the to-be-started outdoor unit is located has a large demand for air conditioners, for example, an underground garage can have a small demand for air conditioners, and an office can have a large demand for air conditioners.

[0084] In this embodiment, the centralized control device can score the to-be-started outdoor unit according to the attribute parameter such as the power size of the to-be-started outdoor unit and the air conditioner demand situation of the working area, to obtain a first score. It can be understood that the first score is a fixed score of the to-be-started outdoor unit, which can be stored by the centralized control device and directly obtained when the priority score needs to be calculated later.

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

[0086] In a possible implementation manner, the priority score can 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 starting order of the to-be-started outdoor unit is.

[0088] In this embodiment, since the priority score considers the fixed attribute parameters such as the overall power of the to-be-started outdoor unit and the location thereof, and the dynamic operation parameters such as the number of faults and the service life, the priority of the to-be-started outdoor unit can be determined according to the actual situation of the to-be-started outdoor unit, so as to achieve the corresponding optimization target, for example, starting the to-be-started outdoor unit with a smaller power first, and then starting the to-be-started outdoor unit with a larger power; starting the to-be-started outdoor unit in a region with a large demand for air conditioners first, and then starting the to-be-started outdoor unit in a region with a small demand for air conditioners, etc.

[0089] Optionally, since each air conditioner outdoor unit is connected with a small number of air conditioner indoor units, and the overall power of the to-be-started outdoor unit is considered when the sequence is considered, it is not necessary to sequence the to-be-started indoor units connected with each air conditioner outdoor unit.

[0090] In step S23, each to-be-started outdoor unit is controlled to start and run in sequence according to the starting order, so that the to-be-started outdoor unit controls the to-be-started indoor unit connected therewith to start and run.

[0091] Optionally, in order to facilitate accurate identification and accurate control of each outdoor unit, the central control device can further store the overall network architecture of the multi-split air conditioning system, for example, which indoor unit in which room in which area can be controlled through which outdoor unit located in which area, so that the central control device can accurately control each to-be-started outdoor unit to start running in sequence according to the start sequence.

[0092] Optionally, the central control device can further send information of the to-be-started indoor unit corresponding to the to-be-started outdoor unit to the to-be-started outdoor unit, so that the to-be-started outdoor unit can control the corresponding to-be-started indoor unit to start running after starting.

[0093] It can be understood that this way can also reduce the maintenance cost of air conditioning information. For example, if some information of a certain outdoor unit or indoor unit needs to be modified, it is not necessary to modify the configuration on a large scale, but only the related information in the overall network architecture needs to be updated.

[0094] The air conditioner control method provided by the embodiment of the application can determine the to-be-started outdoor unit and the to-be-started indoor unit from the plurality of outdoor units and the plurality of indoor units according to the standby parameters, the state parameters before power failure and the component state parameters corresponding to each outdoor unit and each indoor unit when the multi-split air conditioning system is powered on, then calculate the priority scores of each to-be-started outdoor unit according to the attribute parameters and the operating parameters of each to-be-started outdoor unit, determine the start sequence of each to-be-started outdoor unit according to the priority scores of each to-be-started outdoor unit, and control each to-be-started outdoor unit to start running in sequence according to the start sequence, and then control each standby indoor unit connected to the to-be-started outdoor unit to start running by the to-be-started outdoor unit. In this way, it is not necessary to pre-set the start time, and the central control device sets the start sequence of each outdoor unit according to the actual situation of the multi-split air conditioning system, so as to start in sequence. This can not only avoid the impact on the power supply caused by the simultaneous start of a large number of units, improve the start safety, but also improve the intelligent degree, simplify the operation, reduce the setting difficulty, and facilitate installation and debugging.

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

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

[0097] In one possible implementation, in order to facilitate centralized control, a plurality of outdoor units and indoor units with similar locations can be divided into an air conditioning group, for example, all outdoor units and indoor units in a whole building are taken as an air conditioning group.

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

[0099] In this embodiment, the centralized control device can determine standby outdoor units and standby indoor units from the plurality of air conditioner outdoor units and the plurality of air conditioner indoor units according to the standby parameters, the pre-power-off state parameters and the component state parameters corresponding to each air conditioner outdoor unit and each air conditioner indoor unit in each air conditioner group, and determine the control sequence of each air conditioner group according to the determined sequence of all the standby outdoor units and the standby indoor units in each air conditioner group.

[0100] Alternatively, considering that the standby outdoor units and the standby indoor units in some air conditioner groups are determined faster, and the standby outdoor units and the standby indoor units in some air conditioner groups are determined slower, the centralized control device can first perform the sorting and control of the standby outdoor units for the air conditioner group in which all the standby outdoor units and the standby indoor units are determined first.

[0101] That is to say, if all the standby outdoor units and the standby indoor units included in an air conditioner group are determined first, the centralized control device can set the control sequence of the air conditioner group as 1, and then sequentially sort the air conditioner groups according to the determined sequence.

[0102] In this embodiment, the centralized control device can determine the startup sequence of each standby outdoor unit according to the priority score of each standby outdoor unit in each air conditioner group, determine the target air conditioner group to be started according to the control sequence of each air conditioner group, and sequentially control each standby outdoor unit to start operating according to the startup sequence of each standby outdoor unit in the target air conditioner group.

[0103] Alternatively, the centralized control device can sort the standby outdoor units in each air conditioner group, and then determine the target air conditioner group to be started according to the control sequence of the air conditioner group. For example, the air conditioner group with a control sequence of 1 is determined as the target air conditioner group, and the standby outdoor units therein are sequentially started according to their corresponding startup sequences, then the air conditioner group with a control sequence of 2 is determined as the target air conditioner group, and the standby outdoor units therein are sequentially started according to their corresponding startup sequences, and so on.

[0104] Alternatively, in order to ensure that the air conditioner outdoor units and the air conditioner indoor units can be successfully started, the air conditioner outdoor units and the air conditioner indoor units with normal state and no component failure can be selected as the standby outdoor units and the standby indoor units.

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

[0106] Next, a possible implementation is provided for how to determine the standby outdoor unit and the standby indoor unit from the plurality of air conditioner outdoor units and the plurality of air conditioner indoor units according to the standby parameter, the power-off state parameter and the component state parameter.

[0107] Specifically, for each air conditioner outdoor unit, if the standby parameter corresponding to the air conditioner outdoor unit indicates that the air conditioner outdoor unit is in the standby normal state and the power-off state parameter indicates that the air conditioner outdoor unit is in the normal running state before power-off, it is determined according to the outdoor unit component state parameter of the air conditioner outdoor unit whether each outdoor unit component of the air conditioner outdoor unit has a component fault.

[0108] It can be understood that if each outdoor unit component of the air conditioner outdoor unit does not have a component fault, the air conditioner outdoor unit is determined as the standby outdoor unit.

[0109] Optionally, the centralized control device can determine for each air conditioner outdoor unit whether the air conditioner outdoor unit is in the standby normal state according to the corresponding standby parameter, and if in the standby normal state, determine whether the air conditioner outdoor unit is in the normal running state before power-off according to the power-off state parameter.

[0110] Optionally, the power-off state parameter can include a compressor running parameter, a temperature set value, a wind speed, etc.

[0111] Optionally, if the air conditioner outdoor unit is in the normal running state before power-off, component fault detection can be performed on the air conditioner outdoor unit.

[0112] In addition, for each air conditioner indoor unit, if the standby parameter corresponding to the air conditioner indoor unit indicates that the air conditioner indoor unit is in the standby normal state and the power-off state parameter indicates that the air conditioner indoor unit is in the normal running state before power-off, it is determined according to the indoor unit component state parameter of the air conditioner indoor unit whether each indoor unit component of the air conditioner indoor unit has a component fault.

[0113] It can be understood that if each indoor unit component of the air conditioner indoor unit does not have a component fault, the air conditioner indoor unit is determined as the standby indoor unit.

[0114] Optionally, the centralized control device can determine for each air conditioner indoor unit whether the air conditioner indoor unit is in the standby normal state according to the corresponding standby parameter, and if in the standby normal state, determine whether the air conditioner indoor unit is in the normal running state before power-off according to the power-off state parameter.

[0115] Optionally, the power-off state parameter can include a refrigeration and heating state, a temperature set value, a wind speed, etc. Optionally, if the air conditioner outdoor unit is in the normal running state before power-off, component fault detection can be performed on the air conditioner outdoor unit.

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

[0117] Specifically, the centralized control device can determine whether the outdoor component parameter of each outdoor component of the air conditioner outdoor unit exceeds the first parameter threshold corresponding to the outdoor component.

[0118] In this embodiment, if the outdoor component parameter of the outdoor component does not exceed the first parameter threshold corresponding to the outdoor component, the centralized control device can determine that the outdoor component does not have a component failure. If the outdoor component parameter of the outdoor component exceeds the first parameter threshold corresponding to the outdoor component, the centralized control device can perform failure processing on the outdoor component according to the pre-stored failure processing logic.

[0119] Optionally, the first parameter threshold corresponding to each outdoor component is stored in the centralized control device. The first parameter threshold is a default value when the air conditioner outdoor unit is powered on for the first time. After that, the air conditioner outdoor unit can update the default value according to the historical application data of each outdoor component, so that the first parameter threshold is more suitable for the actual application of the air conditioner outdoor unit.

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

[0121] Optionally, after processing the outdoor component, the centralized control device can reacquire the current outdoor component parameter of the outdoor component, and determine whether the outdoor component has a component failure according to the outdoor component parameter.

[0122] Optionally, considering that there are many components of the air conditioner outdoor unit, there may be a problem of repeatedly acquiring the same parameter and simultaneously judging. Therefore, in order to avoid unnecessary loops or repeated operations, the centralized control device can also determine whether the outdoor component parameter is repeated in the case that the outdoor component does not have a component failure.

[0123] It can be understood that if the outdoor component parameter is repeated, other repeated outdoor component parameters can be deleted to prevent invalid judgment.

[0124] Optionally, the central control device can also determine whether the number of times of repeated fault determination of the outdoor unit component reaches a first preset number of times, considering that there can be a problem that cannot be solved. Optionally, the first preset number of times can be set according to actual application. In one possible implementation, the first preset number of times can be 3.

[0125] Optionally, if the number of times of fault determination of the outdoor unit component reaches the first preset number of times, the central control device can determine that the outdoor unit component has a component fault, and issue an alarm information.

[0126] It can be understood that if the number of times of fault determination reaches the first preset number of times, it means that the pre-stored fault handling logic cannot solve the problem, and therefore an alarm information can be issued to enable a staff to maintain the fault.

[0127] In addition, if a corresponding fault handling logic cannot be matched, an alarm information can also be issued to enable a staff to maintain the fault.

[0128] In this embodiment, if the outdoor unit component has a component fault that cannot be solved by the pre-stored fault handling logic, it cannot be started, and therefore the air conditioner outdoor unit cannot be used as a standby start outdoor unit.

[0129] Next, a possible implementation of how to determine whether each indoor unit component of an air conditioner indoor unit has a component fault according to an indoor unit component state parameter of the air conditioner indoor unit is provided.

[0130] Specifically, the central control device can determine, for each air conditioner indoor unit, whether an indoor unit component parameter corresponding to the indoor unit component exceeds a second parameter threshold value corresponding to the indoor unit component.

[0131] In this embodiment, if the indoor unit component parameter corresponding to the indoor unit component does not exceed the first parameter threshold value corresponding to the indoor unit component, the central control device can determine that the indoor unit component does not have a component fault, and if the indoor unit component parameter corresponding to the indoor unit component exceeds the second parameter threshold value corresponding to the indoor unit component, the central control device can handle the indoor unit component according to the pre-stored fault handling logic.

[0132] Optionally, the central control device stores a second parameter threshold value corresponding to each indoor unit component, which is a default value in the case of first power-on use of the air conditioner indoor unit, and the default value can be updated according to historical application data of each indoor unit component thereafter, so that the first parameter threshold value is more suitable for the actual application of the air conditioner indoor unit.

[0133] Optionally, if the indoor unit component parameter exceeds the second parameter threshold value, there can be a fault, and therefore the central control device can handle the indoor unit component according to the pre-stored fault handling logic.

[0134] Optionally, the centralized control device can reacquire the current internal component parameter of the internal component, determine whether the internal component parameter exceeds the second parameter threshold, until the internal component parameter does not exceed the second parameter threshold, or the corresponding number of times of fault determination of the internal component reaches the second preset number of times.

[0135] Optionally, after processing the internal component, the centralized control device can reacquire the current internal component parameter of the internal component, and determine whether the internal component has a component fault according to the internal component parameter.

[0136] Optionally, considering that there are many internal components of the air conditioner, the same parameter may be repeatedly acquired and determined at the same time, therefore, in order to avoid unnecessary cycles or repeated operations, the centralized control device can also determine whether the internal component parameter is repeated when it is determined that the internal component does not have a component fault.

[0137] It can be understood that if the internal component parameter is repeated, other repeated internal component parameters can be deleted to prevent invalid determination.

[0138] Optionally, considering that there may be problems that cannot be solved, the centralized control device can also determine whether the number of times of repeated fault determination of the internal component reaches the second preset number of times.

[0139] Optionally, the second preset number of times can be set according to actual application conditions. In one possible implementation manner, 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 times of fault determination corresponding to the internal component reaches the second preset number of times, the centralized control device can determine that the internal component has a component fault, and issue an alarm information.

[0141] It can be understood that if the number of times of fault determination reaches the second preset number of times, it means that the pre-stored fault processing logic cannot solve the fault problem, and therefore an alarm information can be issued to enable a staff to maintain the fault.

[0142] In addition, if a corresponding fault processing logic cannot be matched, an alarm information can also be issued to enable a staff to maintain the fault.

[0143] In the embodiment, if the internal component has a component fault that cannot be solved by the pre-stored fault processing logic, it cannot be started, and therefore the air conditioner internal machine cannot be used as a to-be-started internal machine.

[0144] Optionally, considering that if the air conditioner external machine is not a to-be-started external machine, the air conditioner internal machine connected thereto cannot be normally started, and therefore the air conditioner internal machines corresponding to these air conditioner external machines can not be used as to-be-started internal machines.

[0145] Similarly, if all the indoor units connected to a certain outdoor unit are not the target indoor unit, the outdoor unit is not required to be started even if it is a target outdoor unit, and thus the outdoor unit can not be regarded as a target outdoor unit.

[0146] In a possible implementation, the delay time can also be stored in the centralized control device, and the centralized control device can control each target outdoor unit to start according to the starting order corresponding to each target outdoor unit and the preset delay time.

[0147] Optionally, the centralized control device can control each target outdoor unit to start by issuing a delay instruction to each target outdoor unit, and the delay instruction can include a delay duration, indicating that the target outdoor unit can wait for the delay duration before starting after receiving the instruction.

[0148] In an example, if the starting order of a certain target outdoor unit is n and the delay time is T, the centralized control device can issue a delay instruction to the target outdoor unit, instructing the target outdoor unit to start after a delay of nT.

[0149] Optionally, considering that there can be a large power grid load and / or a fault of a target outdoor unit during actual starting, the centralized control device can also monitor the power grid load and the device status of the target outdoor unit during actual starting.

[0150] Specifically, the centralized control device can obtain the power grid load parameter and the status parameter of each target target outdoor unit that has not started in real time while controlling each target outdoor unit to start according to the starting order.

[0151] In this embodiment, if the power grid load parameter indicates that the power grid load exceeds a preset load, the centralized control device stops controlling each target target outdoor unit to start, and if the status parameter of a target target outdoor unit indicates that the target target outdoor unit has a fault, the target target outdoor unit is skipped.

[0152] Optionally, if the power grid load exceeds the preset load, the centralized control device can no longer start the target outdoor unit that has not started, and if a target target outdoor unit suddenly has a fault, the centralized control device can skip the target target outdoor unit and start the next target outdoor unit of the target target outdoor unit.

[0153] It can be understood that, in this way, the starting process of the multi-split air conditioning system can be more adaptive to changes in actual conditions, and the entire starting process can be smooth and fault-free, improving the starting efficiency.
