Example Embodiment

[0040] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] refer to figure 1 , propose an embodiment of a method for detecting electrical faults of the present invention, comprising the following steps:

[0042] Step 10: Detect the current state of each module of the electrical appliance to obtain the current performance index parameters of each module and output it; The current performance index parameters corresponding to the module. The performance index parameters of each unit and module can be extracted through the test of the module or directly. The performance index parameters include the corresponding parameters such as current, voltage, temperature, etc. The performance index parameters that need to be detected by different electrical appliances are different. In the above embodiment, the detection of electrical appliances can be performed periodically and a...

Abstract

The invention discloses an electric appliance fault detection method which comprises the following steps of: respectively detecting the current states of all modules of an electric appliance to obtain the current performance index parameters of all the modules, and outputting the current performance index parameters; and receiving the current performance index parameters, comparing the current performance index parameters with the prestored normal performance index parameters, and judging the position of the fault according to the comparative result. The invention also discloses electric appliance fault detection device and system. The specific fault of the electric appliance is determined by automatically detecting and analyzing the performance index parameters of the electric appliance, thereby saving plenty of workload of manual detection, saving labor power and material resources and positioning the fault unit or module in time with high efficiency and accuracy.

Description

technical field [0001] The invention relates to electrical fault detection, in particular to an electrical fault detection method, device and system. Background technique [0002] When a fault occurs in a smart electrical appliance, at present, various instruments are used to manually eliminate and detect each device and module one by one. This method is time-consuming, laborious and inefficient, and it is difficult to accurately locate the fault location. If a large or complicated electrical appliance breaks down, manual detection requires a lot of work. If the specific location of the electrical failure can be determined through automatic detection, it will greatly save manpower and material resources. [0003] Therefore, how to realize the automatic detection of electrical products to determine the fault condition is a technical problem to be solved urgently in the industry. Contents of the invention [0004] The main purpose of the present invention is to provide an e...
