This paper aims at the overhead line payout operation of transmission lines in uninhabited areas and areas without signal coverage,and solves the problem that it is difficult to realize real-time monitoring under these conditions.This paper studies how pay-off operators can obtain real-time surveillance video in the field without network communication signals,so as to improve the operation standardization and accuracy of transmission line overhead pay-off operation,so as to ensure that the potential risks and defects in transmission line operation can be effectively controlled.
