Terminal upgrading method and device based on traceability and result verification, and terminal equipment

Abstract

The invention provides a terminal upgrading method and device based on traceability and result verification and terminal equipment, and relates to the technical field of power distribution Internet of Things, and the method comprises the steps: executing an upgrading operation on at least one to-be-upgraded target of a current terminal through external storage equipment under the condition that the external storage equipment passes identity verification, generating upgrading result information of each to-be-upgraded target; if it is determined that upgrading of the current to-be-upgraded target fails, upgrading feature information is determined based on upgrading result information of the current to-be-upgraded target, and the current upgrading feature information serves as input, and a retry success probability of the current to-be-upgraded target is generated through a preset retry prediction model; if the retry success probability is higher than a preset threshold value, upgrading retry operation is carried out on the current to-be-upgraded target, otherwise, the upgrading retry operation is terminated, and upgrading result information of the current to-be-upgraded target is updated and stored in external storage equipment. According to the method, the security of the terminal equipment can be effectively improved, and the success rate of upgrading retry operation is improved.
