Abstract: A parameter backup method includes monitoring parameter information of an air conditioning unit in real time, and, in response to determining, according to the parameter information, that a key parameter of the air conditioning unit changes, backing up at least the key parameter to obtain backup data.

Abstract: A remote debugging method includes determining one or more detection stages in a trial operation process of an air conditioning unit. Each of the one or more detection stages is provided with a corresponding data acquisition rule. The method further includes acquiring key point data of each of the one or more detection stages according to a data acquisition rule corresponding to the detection stage, and, in response to ending of the trial operation process of the air conditioning unit, determining a trial operation result of the air conditioning unit, and uploading data according to the trial operation result.
