Preferably, the detection report includes the type of the water heater, the detection time and the detection place.
In detail, the detection report not only includes the detection result, but also includes the detected water heater model, the detection time and the detection place. The method has strong guiding significance for analyzing the reason of the water heater fault due to the type, the detection time and the detection place of the water heater, for example, the fault causes of the same fault for different water heaters may be different, and after the water heater model and the detection result are uploaded to the cloud server, the cloud server can analyze big data aiming at the faults of the water heater with the model to obtain the reasons of the faults, and maintenance personnel can set the priority level according to the reasons recommended by the cloud server when detecting the faults next time, thereby further improving the working efficiency, meanwhile, the labor and the material resources are saved, and similarly, the reasons for the same fault in different seasons may be different and the detection places are different when the detection time is different, such as in winter and summer, for example, south and north, the cause of the same fault occurring in different locations may also be different.
