Storage parallel self-checking system and method after power-on

The invention discloses a post-power-on storage parallel self-checking system and method, and relates to the technical field of memory self-checking, the system comprises a cloud platform, and the cloud platform is in communication connection with a self-checking judgment module, a self-checking execution module, a central processor module and a maintenance matching module; whether storage self-inspection is started or not is judged through a self-inspection judgment module; performing storage self-inspection of the memories through a self-inspection execution module, setting a timing counter for counting, and setting a self-inspection mark after storage self-inspection of all the memories is completed; acquiring a self-checking mark through a central processing unit module, judging whether the self-checking mark accords with a set time window or not, if so, emptying the numerical value of a timing counter and skipping to a main program, and if not, generating an overflow mark and triggering non-maskable inte
