The invention discloses a non-contact safe distance active early warning method and device and a storage medium. The method comprises the following steps: acquiring positioning data of an engineering vehicle and an operator based on an inertial sensor; performing error compensation on the inertial sensor by using Kalman filtering and inertial pose error estimation, and obtaining positioning data after error compensation; acquiring operation site environment data of the engineering vehicle and the personnel; and determining whether the engineering vehicle or the personnel is within the non-contact safety distance of the transformer substation or not based on the positioning data after error compensation and the operation site environment data, and performing active early warning under the condition that the engineering vehicle or the personnel is beyond the non-contact safety distance of the transformer substation. The technical problem that early warning cannot be effectively carried out due to inaccurate pos
