In the process of detecting the faults, a user cannot visually see the positions of the faults, and the faults generally cause no small trouble to the user.
For the fault detection of household appliances, taking a photovoltaic air conditioner as an example, the prior art mainly provides the following solutions:
1) by utilizing a log recording function in the photovoltaic air conditioner, when the photovoltaic air conditioner breaks down, the key information of the fault is recorded in a fixed position in a storage area of the photovoltaic air conditioner. When a user takes the photovoltaic air conditioner to a maintenance point, maintenance personnel can read out the fault information through special software and hardware and then analyze and locate the fault problem. However, this solution has the following drawbacks: a. the storage area space of the photovoltaic air conditioner is limited, the system can only record the latest fault information, and when the storage space is insufficient, the new fault information covers the old fault information, so that the fault information is recorded incompletely; b. the photovoltaic air conditioner needs to be sent to a maintenance point, fault information is read through special software and hardware, and the collection of the fault information is not timely and popular.
2) By collecting fault information on line, specifically reporting fault parameters generated by faults of the photovoltaic air conditioner to a server, when a user takes the photovoltaic air conditioner to a maintenance point, a maintenance worker searches fault parameters corresponding to the photovoltaic air conditioner from the server, and then locates fault problems through a fault parameter analysis system. However, this solution has the following drawbacks: the fault location method comprises the steps that a parameter is presented to a user when a fault occurs each time, the user cannot directly locate the position of the fault, analysis is conducted by a professional or a professional fault parameter analysis system, if the fault is located by the professional, the fault point cannot be accurately located due to the fact that the professional is not professional enough, if the fault location is needed by the professional and the professional fault parameter analysis system, equipment needs to be taken to a professional maintenance center, and maintenance efficiency is low.
