Therefore, the server can conveniently and timely acquire the operation data of a plurality of fault air conditioners.
Fig. 1 is a flowchart of a control method for an air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, an embodiment of the present disclosure provides a control method for an air conditioner, which may include:
and S11, the processor obtains respective historical faults of a plurality of fault air conditioners in the same region and the same machine type within a preset time length and historical fault related parameters associated with the historical faults.
Wherein, the value range of the preset duration can be 1 year to 5 years.
The historical fault related parameters can be embodied as air conditioner operation parameters which are strongly related to different historical faults. In an actual application process, if a compressor discharge protection fault occurs, the air conditioner operation parameters strongly related to the fault may be a compressor operation frequency, an expansion valve opening degree, and an outdoor ambient temperature.
Due to the fact that the similarity between fault data of a plurality of fault air conditioners in the same region and the same type is high and the fault data are comparable, historical faults of the plurality of fault air conditioners in the same region and the same type in a preset time period and historical fault related parameters related to the historical faults are obtained, and the change rule of the historical fault related parameters related to the historical faults along with the time can be obtained through analysis of a subsequent processor. In addition, since the preset time is in units of years, the fault data of the fault air conditioner needs to be classified so as to avoid that the data amount needing to be processed is too large to obtain the change rule.
The embodiment of the disclosure can provide multiple implementation manners to obtain respective historical faults of multiple fault air conditioners in the same area and the same machine type within a preset time length and historical fault related parameters associated with the historical faults. The following examples are given.
In one mode, if the processor can establish communication connection with the plurality of faulty air conditioners respectively, the processor can collect respective historical faults of the plurality of faulty air conditioners and historical fault related parameters associated with the respective historical faults within a preset time period.
In another mode, if the historical faults of the plurality of faulty air conditioners and the historical fault related parameters associated with the historical faults are stored in an air conditioner information base, and the air conditioner information base is stored in a server associated with the processor, the processor can obtain the historical faults of the plurality of faulty air conditioners and the historical fault related parameters associated with the historical faults from the air conditioner information base in a local reading mode when needed. Or, if the air conditioner information base is stored in another data storage server, the processor may obtain the historical faults of each of the plurality of faulty air conditioners stored in the air conditioner information base and the historical fault related parameters associated with each of the historical faults by accessing the data storage server when needed.
By adopting the mode, the processor can conveniently and quickly obtain the respective historical faults of the plurality of fault air conditioners and the historical fault related parameters associated with the historical faults.
And S12, the processor generates a change rule of the historical fault related parameters associated with each historical fault along with time.

Therefore, the change interval of the historical fault related parameters of the available faults of the same type along with the time can be obtained, the follow-up comparison of the operation parameters of the new fault air conditioner is facilitated, the fault detection is automatically and timely carried out on the air conditioner, manual detection is not needed, the maintenance time of maintenance personnel can be saved, and the use experience of a user is improved.
And S13, under the condition that the new fault air conditioner exists, the processor obtains the operation parameters of the new fault air conditioner within the preset time length.
Here, the embodiments of the present disclosure may provide various implementations to obtain the operation parameters of the new malfunctioning air conditioner. The following examples are given.
In one mode, if the processor can establish a communication connection with the new faulty air conditioner, the processor can directly obtain the operating parameters of the new faulty air conditioner.
In another mode, if the operation parameters associated with each of the plurality of air conditioners are stored in an air conditioner information base, and the air conditioner information base is stored in a server associated with the processor, the processor may obtain the new operation parameters of the faulty air conditioner from the air conditioner information base in a local reading mode when the new operation parameters of the faulty air conditioner need to be determined. Or, if the air conditioner information base is stored in another data storage server, the processor may obtain the operation parameters of the new failed air conditioner stored in the air conditioner information base by accessing the data storage server when needed.
By adopting the mode, the processor can conveniently and quickly obtain the new operation parameters of the fault air conditioner.
And S14, the processor determines the target fault corresponding to the operation parameter according to each change rule and sends a prompt to a user associated with the new fault air conditioner.
Optionally, the determining, by the processor, the target fault corresponding to the operation parameter according to each change rule may include: and in the case that the operation parameter is in the available parameter change interval, the processor determines the available fault as the target fault. Therefore, fault detection can be automatically and timely carried out according to the operation parameters of the new fault air conditioner, manual detection is not needed, maintenance time of maintenance personnel is saved, and use experience of a user is improved.
Optionally, the embodiments of the present disclosure may provide various implementation manners to send a reminder to a user associated with a new faulty air conditioner, which is illustrated below.
In one mode, if the new fault air conditioner is configured with the information reminding module, the processor triggers the information reminding module to send fault reminding information to the user by issuing a reminding instruction to the information reminding module. For example, the information reminding module can be embodied as a voice broadcasting module, and the fault type can be broadcasted through voice. Or, the information reminding module can be embodied as an air conditioner display screen, and the fault type can be displayed through the air conditioner display screen.
In another mode, if the processor can perform wireless communication with the terminal device associated with the user, the processor can directly send the fault reminding information to the terminal device for the user to check.
Here, the means of wireless communication includes one or more of a Wi-Fi connection, a zigbee protocol connection, and a bluetooth connection.
