Multi-fault diagnosis method and system for electronic information system

The invention discloses an electronic information system multi-fault diagnosis method and system, and relates to the technical field of electronic information system multi-fault diagnosis. The method comprises the following steps: acquiring surrounding environment characteristics, determining parameters of the system when the electronic information system has no fault according to the influence of the environment on the parameters, and obtaining comparison parameter data; according to the comparison parameter data, real-time parameters are detected, the comparison parameters and the real-time parameters are compared, and whether the system breaks down or not is diagnosed; if the real-time parameters are consistent with the comparison parameters, it is diagnosed that no fault occurs, and fault-free data are obtained; if the real-time parameters are not consistent with the comparison parameters, the system is diagnosed to have faults, and preliminary diagnosis data are obtained; based on the preliminary diagnos
