The invention discloses a design method of an intelligent cloud computing system of test paper background processing. The intelligent cloud computing system is divided into a convergence layer, a whole paper processing layer, a cutting layer, a backup cutting layer, a subjective item service layer, an objective item judging layer, an objective item debugging layer and a core layer. The core layer is composed of a data base and a dispatch server, the other layers are server groups, and the dispatch server distributes server tasks of the layers in a unified mode. The intelligent cloud computing system is divided into different layers, and each layer achieves different functions, so that safety, reliability, security and popularization of the system are improved, intellectualization and automation of earlier test paper image processing are achieved, simultaneously high-standard requirements for data security and confidentiality during paperless paper inspection are achieved, and profession quality requirements for server performance and data administrators are reduced.
