Safety early warning method, device and system and computer storage medium

Abstract

The invention discloses a safety early warning method, device and system and a computer storage medium. The method comprises the following steps: respectively scanning a transformer substation with first preset precision and second preset precision to obtain a pre-scanning model and a correction scanning model; obtaining a rotation value and a translation value according to the pre-scanning model and the correction scanning model; performing subsequent multiple identification scanning with second preset precision on the transformer substation in real time, and correcting an identification scanning model obtained by each identification scanning according to the rotation value and the translation value to obtain a corrected identification model, wherein in the process, the correction time of an operator is saved, and the correction speed is increased; obtaining a target object in the correction recognition model; calculating a real-time distance from the target object to a cable in the pre-scanning model; and judging whether to perform safety early warning on the target object according to the real-time distance. The position of the target object in the transformer substation can be judged so as to ensure that early warning is performed in time to avoid the safety problem before the safety problem occurs, and meanwhile, accurate and real-time problems are ensured.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a safety early warning method, device, system and computer storage medium. Background technique [0002] For the monitoring of the safe distance of cables in substations, the current technology is mainly used to avoid cables when controlling UAV detection. In this scenario, only the height of the cable at each point in the fine model is recorded, and the height of the UAV relative to the cable is obtained by comparing the height of the current position of the UAV. [0003] However, people, vehicles, and animals entering the field cannot carry height sensors with them like drones. The location information of people, vehicles, and animals in space needs to be detected in real time through external devices. This leads to the need for accurate and fast detection equipment when judging the position of foreign objects in the substation. [0004] The precision lies in that the ca...
