The invention provides an information early warning and self repairing system and method. The system comprises a database used for storing a normal device state data value, a flow value and a plurality of fault models, an analyzing module used for analyzing real-time fault existing in data and calling a corresponding fault model for removing the fault, a self repairing module used for conducting self repairing on the simple fault and transmitting the repaired result to an early waning module and the early warning module used for receiving results of the analyzing module and the self repairing module and transmitting a fault name and a processing result to a monitoring worker. The method includes the following steps: 1) determining abnormal data in the monitored data; 2) analyzing and displaying fault information; 3) transmitting early warning information; 4) self repairing the fault; 5) conducting worker reviewing. By means of the system and method, judgment, self repairing and early warning of the monitored data are achieved, the intelligent degree of the monitoring system is greatly improved, and the working efficiency is improved.
