Abstract

The embodiment of the present invention relates to an alarm method, system and equipment for positioning a safe distance in a three-dimensional scene of a substation. By obtaining the first point cloud data in the three-dimensional scene in the substation, a data space and a space coordinate system with a three-dimensional scene of the real scene model of the substation are established. Use segmentation technology to divide the data space into several unit blocks and establish a local coordinate system corresponding to each unit block, and sparse the first point cloud data in each unit block into the second point cloud data, and calculate each unit block If the absolute value of the subtraction of the value of the center coordinates and the coordinates of the positioning object is greater than the safety distance, an alarm will be issued, so that the moving objects in the substation will automatically alarm when they enter the dangerous area, improving the safety control ability of the substation operation and reducing the risk of substation. The risk of operating personnel solves the technical problems of poor safety risk management and high operating risk in existing substations.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to an alarm method, system and equipment for positioning a safe distance in a three-dimensional scene of a substation. Background technique [0002] Substation refers to the place where voltage and current are transformed, received and distributed in the power system; the substation in the power plant is a step-up substation, and its function is to boost the power generated by the generator and feed it to the high-voltage power grid. [0003] Due to the diversification of the substation operating environment and the complex and changeable equipment operating in the substation, this makes the safety inspection of the substation encounter major challenges. If the traditional safety management process is used to carry out safety inspections on substations, it will bring greater danger to the operators, and the changing operating environment makes operators with different job respon...
