Zusammenfassung:The invention relates to an automatic diagnosis method for a full-working-condition vibration fault of a turboset and a computer readable medium. The automatic diagnosis method comprises the following steps: step 1, establishing a full-working-condition database; 2, vibration data and operation parameter data during operation of the turboset are monitored in real time; 3, if the difference value between the vibration data and the data in the all-condition database exceeds a preset threshold value, executing the step 4; 4, the vibration abnormity occurrence position, the state of the steam turbine set when vibration abnormity occurs and the characteristic parameters of the position in the current state are sequentially determined; and step 5, according to the characteristic parameters determined in the step 4, comparing the parameter values collected in real time with the parameter values in the full working condition database to obtain a fault diagnosis result. Compared with the prior art, the method has the
