Method and device for categorizing self-service terminal problem

The present invention discloses a method and device for categorizing self-service terminal problems. A self-service terminal system is layered according to the runtime environment, the layered operating environment comprises an application layer, a system layer and a hardware layer, resources of the layers of the self-service terminal system are classified according to business requirements, and the classified resources are divided into suspicious items and non-suspicious items according to problem phenomena, thereby modelling the self-service terminal system and raising accuracy for analyzing the self-service terminal problems.
