A generating method and device for fault spectra, and a detecting method and device based on fault spectra. The generating method comprises: acquiring one or more categories of first work order data (101), wherein each piece of first work order data comprises fault information and detection information; extracting a public feature word from the detection information as a feature vector aiming at each category of first work order data (102); learning a logic relationship between the fault information and the feature vector aiming at each category of first work order data, and acquiring a model about each category of fault spectra (103); and performing trimming treatment on the model about each category of fault spectra, and acquiring each category of fault spectra (104). By establishing fault spectra, concurrency detection is supported to be performed according to one or more detecting paths during follow-up detection, thereby reducing the time consumed for detection, and increasing detection efficiency; and meanwhile, the detection operation for applying the fault spectra is simple, thereby greatly reducing the participation frequency of manpower, and reducing the consumption of vigor of a user. |
