Based on the hardware architecture, the embodiment of the control method of the multi-split air conditioning system is provided.
Referring to fig. 2, fig. 2 is a first embodiment of a control method of a multi-split air conditioning system according to the present invention, the control method of the multi-split air conditioning system including the steps of:
step S10, acquiring a default priority operation mode of the multi-split air conditioning system and mode selection signals received by a plurality of indoor units of the multi-split air conditioning system;
in this embodiment, the default priority operation mode may be a priority operation mode given to the multi-split air conditioning system in the current environment according to one or more of parameters of a current season, a current time period, a current time, a temperature distribution of the current time, a current geographical area, and the like. When the multi-split air conditioning system is installed for the first time, since there is no initial priority mode record in the local database, the various parameters described above may be obtained from the cloud to determine the default priority operation mode. Of course, when the multi-split air conditioning system is started next time, the default priority operation mode can be directly called from the local database, and the required parameters can be acquired from the cloud in real time, so that a more preferable default priority operation mode is obtained.
Assuming that the multi-split air conditioning system comprises 1 outdoor unit and 7 indoor units, the indoor units in different areas or different rooms are triggered by different users in the same time period, and therefore, mode selection signals received by different indoor units may be different. Of course, the same user may enter different areas or different rooms in sequence according to different needs to start the indoor unit, and the mode selection signals received by different indoor units may be different. For example, when the current time period is 10:00 to 12:00 in the morning of summer, 2 indoor units receive mode selection signals as a cooling mode, 4 indoor units receive mode selection signals as an air supply mode, and 1 indoor unit receives mode selection signals as a heating mode. Of course, there are also indoor units that have not received the mode selection signal, i.e., some indoor units are not activated. The triggering of the mode selection signal may be triggered by a user operating a remote controller of the air conditioning system, or may be triggered by a user operating a mobile terminal, such as a corresponding APP on a mobile phone.
Step S20, judging whether the multi-split air conditioner system meets preset conditions or not according to the mode selection signal;
and step S30, when the multi-split air-conditioning system meets the preset condition, switching the default priority operation mode to a corresponding actual priority operation mode, and controlling the multi-split air-conditioning system to execute the actual priority operation mode.
In this embodiment, the preset condition may be that more than a predetermined number of, for example, half of the indoor units all select a mode different from the default priority operation mode, and if the default priority operation mode is heating, but the mode selection signals received by more than half of the indoor units are cooling, the default priority operation mode, for example, heating, needs to be switched to the corresponding actual priority operation mode, for example, cooling.
The preset condition may also be that the sum of the number of the indoor units receiving the same mode selection signal, such as cooling, is compared with the total number of all the indoor units, and if the sum of the number of the indoor units is greater than half of the total number of the indoor units, the default priority operation mode, such as heating, needs to be switched to the corresponding actual priority operation mode, such as cooling.
The preset condition may also be that an indoor unit with the highest priority is determined from the indoor units that receive the mode selection signal, and when the default priority operation mode, such as heating, is inconsistent with the mode selection signal received by the indoor unit with the highest priority, the default priority operation mode, such as heating, needs to be switched to the corresponding actual priority operation mode, such as cooling.
According to the control method of the multi-split air-conditioning system, the default priority operation mode of the multi-split air-conditioning system and the mode selection signals received by the indoor units of the multi-split air-conditioning system are obtained, whether the multi-split air-conditioning system meets the preset conditions or not is judged according to the mode selection signals, when the multi-split air-conditioning system meets the preset conditions, the default priority operation mode is switched to the corresponding actual priority operation mode, and the multi-split air-conditioning system is controlled to execute the actual priority operation mode. Therefore, whether the operation mode is switched or not is determined according to the mode selection signals actually received by the indoor units without additionally setting a priority operation mode manually, so that the problem of system shutdown or fault caused by operation mode conflict is avoided.
Referring to fig. 3, in a second embodiment, based on the first embodiment, the step of acquiring a default priority operation mode of the multi-split air conditioning system in step S10 includes:
step S11, acquiring environment information of the multi-split air-conditioning system at present from a cloud, wherein the environment information comprises one or more of current season, current time period, current air temperature distribution and current geographical area;
in this embodiment, preferably, when the multi-split air-conditioning system is installed for the first time, because there is no initial priority mode record in the local database, the environment information where the multi-split air-conditioning system is currently located may be obtained from a cloud, where the environment information includes one or more of a current season, a current time period, a current air temperature distribution, and a current geographic area. Of course, when the multi-split air conditioning system is started next time, the required parameters can still be obtained from the cloud in real time, so that a more preferable default priority operation mode is obtained.
And step S12, determining a default priority operation mode of the multi-split air conditioning system according to the environment information.
In the embodiment, assuming that the current season is summer, the current time period is 10: 00-12: 00, the current temperature distribution is 28-30 ℃, the current geographical area is Guangdong province (specifically to cities and districts), and the default priority operation mode of the multi-split air-conditioning system can be determined as refrigeration according to the environmental information; assuming that the current season is winter, the current time interval is 20: 00-22: 00, the current temperature distribution is 12-15 ℃, and the current geographical area is Guangdong province (which can be specifically to cities and districts), the default priority operation mode of the multi-split air-conditioning system can be determined as heating according to the environmental information.
Referring to fig. 4, in the third embodiment, based on the first embodiment, the step S20 includes:
step S201, obtaining the consistent number of the mode selection signals received by the indoor units;
in this embodiment, it is assumed that the multi-split air conditioning system includes 1 outdoor unit and 7 indoor units, and a default priority operation mode of the multi-split air conditioning system is heating. When the current time period is 10: 00-12: 00 in the morning of summer, 2 indoor units receive mode selection signals as a refrigerating mode, 4 indoor units receive mode selection signals as an air supply mode, and 1 indoor unit receives mode selection signals as a heating mode.
Step S202, if the mode selection signals exceeding the preset number are different from the default priority operation mode, judging that the multi-split air conditioning system meets the preset condition;
in this embodiment, the predetermined number may be set to 50% of the total number of the indoor units, and since the mode selection signal exceeding the predetermined number is an air supply and is different from the default priority operation mode, it may be determined that the multi-split air conditioning system satisfies a preset condition.
And step S203, if the number of the mode selection signals different from the default priority operation mode does not reach the preset number, judging that the multi-split air conditioning system does not meet the preset condition.
In this embodiment, since the mode selection signals received by 2 indoor units are in the cooling mode, the mode selection signals do not reach 50% of the total number of the indoor units, and do not satisfy the preset condition; similarly, 1 indoor unit receives a mode selection signal as a heating mode, and the mode selection signal does not reach 50% of the total number of the indoor units and does not meet the preset condition.
Referring to fig. 5, in the fourth embodiment, based on the first embodiment described above, the step S20 includes:
step S204, calculating the sum of the matching numbers of the indoor units consistent with the mode selection signal;
step S205, if the sum of the number of matches is larger than half of the total number of matches of the indoor units of the multi-split air-conditioning system, judging that the multi-split air-conditioning system meets a preset condition;
and S206, if the sum of the number of matches is less than or equal to half of the total number of matches of the indoor units of the multi-split air-conditioning system, judging that the multi-split air-conditioning system does not meet a preset condition.
In this embodiment, it is assumed that the multi-split air conditioning system includes 1 outdoor unit and 7 indoor units, and the total number of the indoor units is 22HP, where 1#, 2#, 3#, and 4# indoor units are 4HP, and 5#, 6#, and 7# indoor units are 2 HP. And the default preferential operation mode of the multi-split air-conditioning system is heating. When the current time interval is 10: 00-12: 00 in the morning of summer, if the mode selection signals received by the indoor units of 4#, 5#, 6# and 7# are refrigeration, the sum of the number of the indoor units is 10HP, and the sum of the number of the indoor units is less than half of the total number of the indoor units of the multi-split air-conditioning system, namely 11HP, so that the multi-split air-conditioning system does not meet the preset condition; however, when the mode selection signals received by the 1#, 2#, and 3# indoor units are for cooling, the sum of the number of the indoor units is 12, and the sum of the number of the indoor units is greater than 11HP which is half of the total number of the indoor units of the multi-split air-conditioning system, so that the multi-split air-conditioning system meets the preset condition.
Referring to fig. 6, in a fifth embodiment, based on the first embodiment, the step S20 includes:
step S207, determining the indoor unit with the highest priority according to the mode selection signal;
step S208, if the mode selection signal of the indoor unit with the highest priority is different from the default priority operation mode, judging that the multi-split air-conditioning system meets a preset condition;
in this embodiment, it is assumed that the multi-split air conditioning system includes 1 outdoor unit and 7 indoor units, and the default preferred operation mode is refrigeration. The priority sequence of the indoor units is from high to low as: 1#, 2#, 3#, 4#, 5#, 6#, and 7 #. The mode selection signal received by the indoor unit 1# is heating, the mode selection signal received by the indoor unit 2# is cooling, the mode selection signal received by the indoor unit 3# is air supply, and the mode selection signals received by the indoor units 4#, 5#, 6# and 7# are cooling. Since the mode selection signal received by the 1# indoor unit having the highest priority is different from the default priority operation mode, it may be determined that the multi-split air conditioning system satisfies the preset condition.
And step S209, if the mode selection signal of the indoor unit with the highest priority is the same as the default priority operation mode, determining that the multi-split air conditioning system does not meet a preset condition.
In this embodiment, if the mode selection signal received by the # 1 indoor unit is the same as the default priority operation mode, if the mode selection signal is also for cooling, it is also determined that the multi-split air conditioning system does not satisfy the preset condition, and mode switching is not required.
In the third to fifth embodiments, when it is determined that the multi-split air-conditioning system meets a preset condition, the default priority operation mode is switched to a corresponding actual priority operation mode, and the multi-split air-conditioning system is controlled to execute the actual priority operation mode; and when the multi-split air-conditioning system is judged not to meet the preset condition, controlling the multi-split air-conditioning system to execute the default priority operation mode.
Referring to fig. 7, in a sixth embodiment, based on any one of the above embodiments, before the step S20, the method further includes:
step S40, detecting whether a user-defined mode is preset in the multi-split air conditioning system;
in this embodiment, in an actual application scenario, there is a situation that a user wants to define a mode, and therefore, when the indoor unit receives a mode selection signal, it may be first detected whether the multi-split air conditioning system has the user-defined mode preset, so that the user-defined mode preset by the user is an optimal selection.
Step S50, if yes, controlling the multi-split air conditioning system to execute the user-defined mode;
and step S60, if not, executing the step of judging whether the multi-split air conditioner system meets the preset conditions according to the mode selection signal.
In this embodiment, when it is detected that the multi-split air conditioning system is preset with a user-defined mode, for example, in a 10: 00-12: 00 time period in the morning in summer, the user may directly control the multi-split air conditioning system to execute a refrigeration mode if the user-defined mode preset for the time period is refrigeration; and if the user does not preset the user-defined mode, executing a step of judging whether the multi-split air-conditioning system meets the preset condition according to the mode selection signal.
Referring to fig. 8, in the seventh embodiment, based on any of the above embodiments, after step S30, the method further includes:
and step S70, storing the actual priority operation mode to a local database so that the multi-split air-conditioning system can directly operate the actual priority operation mode previously stored when being started at the same time interval next time.
In this embodiment, assuming that a default priority operation mode of the multi-split air-conditioning system is heating, when a time period is 10: 00-12: 00 in the morning of summer, the multi-split air-conditioning system switches the default priority operation mode to heating of a corresponding actual priority operation mode such as cooling according to the mode selection signal received by the indoor unit, and stores the heating in a local database, and when the multi-split air-conditioning system is started in the next synchronization period, the actual priority operation mode pre-stored in the previous time such as cooling is directly operated.
