Embodiment 1

[0067] A method for calculating a safe distance for live work in a substation, comprising the following steps:

[0068] ①Use lidar point cloud for data acquisition: through lidar measurement technology, directly collect high-precision 3D laser point cloud and high-resolution real-time digital images of substations, and then obtain high-precision 3D substation equipment, facilities, and architectural details. The existing ledger data restores the substation to a true level, and the accuracy of the collected engineering data is required to be centimeter-level, less than or equal to 5 centimeters; the flight parameters adopted by the project team are: flight altitude 150m above the ground, flight speed 10m / s, laser pulse frequency 300,000 Hz. Using Novatel’s SPAN-KVH1750, the final data accuracy of the collected point cloud is: relative horizontal error 10cm, relative elevation error 5cm, absolute horizontal accuracy 30cm, absolute elevation accuracy 20cm, image resolution 5cm, l...

Abstract

The invention discloses a safe distance calculation method for the electrified operation of a transformer substation. The method comprises the following steps of carrying out data acquisition by utilizing a laser radar point cloud, and subjecting point cloud data to classification treatment, wherein during the data classification, the point cloud data are subjected to the intelligent analysis andcalculation or the manual calculation of electrified wires, ground equipment facilities and electrified operation safety distances. According to the calculation method of the invention, electrified wires and equipment safe operation distances are comprehensively detected, so that the working safety of the personnel during the construction process in the transformer substation is ensured. The operation risk is reduced, and the requirements of the construction safety specification in the transformer substation are met. The above safe distance calculation method for the electrified operation of the transformer substation is different from existing universal point cloud segmentation algorithms, wherein the characteristics of the transformer substation are fully considered. The method is aimingat target features, such as the features of wires, equipment and the like in the transformer substation, and serves as a special treatment method for the surface features of the transformer substation.

Description

technical field [0001] The invention relates to the technical field, in particular to a method for calculating a safe distance for live work in a substation. Background technique [0002] In the daily work of operating substations, operators are limited by factors such as work experience and work ability, and there are potential safety hazards of accidentally touching live equipment during daily inspections and arranging safety measures. The condition of the equipment is frequent. For example, in the process of substation maintenance, it is difficult for maintenance personnel to rely on manual visual inspection of the safety distance in the face of adjacent charged intervals during partial interval power outages, which may lead to electric shock accidents for maintenance personnel and mechanical equipment. However, due to reasons such as poor working conditions or unfamiliarity with the factory and station, foreign construction workers have potential safety hazards of accid...
