For example, in a normal case, the voltage at the home of the user is 220V, the power of the heating wire is detected to be 140W, and the rated power of the heating wire is the same as 140W, and no fault is determined at this time. When the voltage is 160V in the user's home, the power of the heater wire is detected to be 74W, which is approximately half of the rated power 140W, and therefore, the heater wire is judged to be faulty. In practice, the heating wire does not fail, since voltage fluctuations do not lead to a deviation in the power detection. According to the method for detecting faults, the actual resistance of the load to be detected is calculated by acquiring the first power detection result, and then the actual resistance is calculated by using the rated voltage according to the third preset algorithm, so that the second power detection result can be obtained. Since the actual resistance of the load to be measured is fixed, the second power detection result calculated by the third preset algorithm does not change due to voltage fluctuation. The influence of voltage fluctuation on fault detection can be avoided, so that misjudgment during fault detection is reduced.

The flowcharts and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to embodiments of the present disclosure. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. In the description corresponding to the flowcharts and block diagrams in the figures, operations or steps corresponding to different blocks may also occur in different orders than that disclosed in the description, and sometimes no specific order exists between different operations or steps. For example, two consecutive operations or steps may actually be performed substantially in parallel, they may sometimes be performed in reverse order, which may be dependent on the functions involved. Each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems which perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.
