Abstract

The invention discloses a remote operation and maintenance method and device for a protection device and a storage medium. The method comprises the steps of receiving a remote permission instruction and a remote operation and maintenance instruction; when the digital certificate signature in the remote permission instruction is successfully verified, judging whether the device identifier in the remote operation and maintenance instruction is consistent with the device identifier in the remote permission instruction; if yes, performing time difference range verification on the remote operation and maintenance instruction; and when the time difference range verification of the remote operation and maintenance instruction passes, judging whether the service type in the remote operation and maintenance instruction is consistent with the service type in the remote permission instruction, and if yes, performing corresponding operation and maintenance operation based on the remote operation and maintenance instruction. According to the method, the time difference range verification is carried out on the remote operation and maintenance instruction, whether the service type in the remote operation and maintenance instruction is consistent with the service type in the remote permission instruction or not is judged, the operation and maintenance safety of the in-station system is comprehensively considered, and the operation and maintenance safety and reliability are effectively improved.
