Abstract

The invention discloses a safety early warning method, device, system and computer storage medium. Wherein, the method includes: respectively scanning the substation with the first preset accuracy and the second preset accuracy to obtain a pre-scan model and a corrected scan model; obtaining rotation values ​​and translation values ​​according to the pre-scan model and the corrected scan model; real-time The substation conducts multiple subsequent recognition scans with the second preset accuracy, and corrects the recognition scan model obtained by each recognition scan according to the rotation value and translation value to obtain a corrected recognition model; this process saves the operator's time for correction , speeding up the correction. Obtain the target object in the correction recognition model; calculate the real-time distance from the target object to the cable in the pre-scan model; judge whether to give a safety warning to the target object according to the real-time distance. The position of the target object in the substation can be judged to ensure timely warning and avoidance of safety problems before they occur, while ensuring accurate and real-time problems.

Description

technical field

[0001] The present invention relates to the technical field of substations, and in particular, to a security 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 obstacles when controlling drones for detection. In this scenario, only the height of the cable at each position in the fine model is recorded, and the height of the drone relative to the cable is obtained by comparing the height of the current position of the drone.

[0003] However, for people, vehicles and animals entering the venue, it is impossible to carry height sensors with them like drones. The location information of people, vehicles and animals in space needs to be detected in real time by external devices. This leads to the need for accurate and fast detection equipment when judging the position of foreign objects in the substation. ...
