The invention relates to a remote station-entering licensing method for an unattended transformer station and an executing system. A worker accesses a remote station-entering licensing WeChat public platform through a smartphone, fills in and submits a station-entering application, and sends the application to a centralized control station dispatching center. The centralized control station dispatching center checks the submitted station-entering application, confirms the identity of the worker to enter the station through WeChat video, and sends a licensing instruction to a server. The server generates a one-time password through a dynamic password generator, and sends the one-time password in a form of a WeChat massage to the smartphone of the worker to enter the station. The worker to enter the station inputs the one-time password into an intelligent door access system to open a corresponding door lock, enters a corresponding working zone and works. Through an internet mutual information technique, a remote-control management platform of the intelligent door access system of the unattended transformer station is built, remote licensing management of worker's entering or leaving the unattended transformer station is achieved, and station entering history information can be traced back and called at any time.
