Boiler flue gas and air system vibration fault diagnosis method

The invention discloses a boiler flue gas and air system vibration fault diagnosis method. At present, a technician field test mode is mostly adopted for vibration fault diagnosis of a flue gas and air system, due to limitation of field measuring point conditions, a diagnosis process only aims at a fan body, a fan is not placed in the whole flue gas and air system for research, and certain one-sidedness remains. Artificial intelligence diagnosis not only can greatly reduce the workload of technicians for processing equipment vibration problems on site but also can monitor the whole flue gas and air system, comprehensive data is obtained, the method is suitable for diagnosing vibration generated by coupling of all factors in the flue gas and air system, and the accuracy of vibration fault diagnosis is greatly improved. According to the invention, a plurality of measuring points are arranged at a flue gas duct and a fan body, the vibration data of the flue gas and air system is comprehensively collected, an art
