Self-management high-reliability information protection method

The invention provides a self-management high-reliability information protection method. The self-management high-reliability information protection method comprises the following steps: collecting node related information of each storage node of each CPM module in an embedded processor; dividing all storage nodes in each CPM module into a plurality of protection groups according to information importance, node storage capacity and protection requirements in the node related information, and performing priority ranking to obtain a protection group priority ranking and a storage node priority ranking in the protection groups; the current total energy of a protection energy input unit connected with each CPM module is detected in real time, and a protection instruction is output according to the current total energy, the priority sequence of the protection groups, the priority sequence of the storage nodes in the protection groups, and the protection duration and the protection current of each storage node; and
