The invention provides a relay valve fault diagnosis method and system, and can be used in the technical field of fault diagnosis. The relay valve fault diagnosis method comprises the steps that displacement data of a valve element and displacement data of a valve rod of a relay valve are collected in real time; according to the displacement data of the valve element and the displacement data of the valve rod, displacement characteristics of the valve element and displacement characteristics of the valve rod are generated; and comparing the displacement characteristics of the valve core and the displacement characteristics of the valve rod with the displacement characteristics of the valve core and the displacement characteristics of the valve rod of the relay valve in a normal working state to obtain a fault diagnosis result of the relay valve. According to the relay valve fault diagnosis method and system provided by the invention, the complexity of fault judgment and performance prediction is reduced, and the judgment accuracy is improved.
