The invention relates to a transformer substation supporting type tubular bus deformation early warning method based on point cloud data. The transformer substation supporting type tubular bus deformation early warning method based on point cloud data comprises the steps of collecting point cloud data of a tubular bus system; creating a cylinder according to the point cloud data; acquiring featurepoints of the cylindrical section; connecting the feature points to create a broken line segment of the tubular bus axis; measuring and calculating the deflection value, the length value and the distance between two ends of the broken line section; and judging whether the deformation of the tubular bus exceeds a deformation threshold or not according to the deflection value, the length value andthe distance between the two ends of the broken line section, and if yes, sending an early warning signal. The method solves the problem that a traditional method cannot accurately measure the lengthand deflection of the bent tubular bus. Meanwhile, the method for approaching the axis of the bent tubular bus through the broken line segment can control the length of the broken line segment to meetthe measurement requirements of tubular buses with different diameters, and has the advantages of being easy and convenient to measure and high in prediction result precision.
Description
technical field [0001] The invention relates to the technical field of substation maintenance, in particular to a method for early warning of substation support pipe parent deformation deformation based on point cloud data. Background technique [0002] The supporting pipe mother system of the substation is generally exposed outdoors, and its safety status is affected by external factors and its own shape. Appropriate spatial posture will help to improve the safety performance of the supported pipe mother system, but due to the installation quality or later state changes, there will be a certain degree of deviation defects, such as excessive deflection of the pipe mother, and large deformation will cause damage to the underlying support structure. Larger force even causes irreversible plastic deformation, which threatens the structural safety of the substation pipe parent system. Therefore, it is of great engineering application value to carry out early warning of the defor...
