This invention discloses a control method for UAV spraying operations on columnar or quasi-column structures, belonging to the field of UAV operation and surveying technology. Targeting the surface characteristics of different types of quasi-column structures, this invention constructs a complete mathematical logic system through three-dimensional data acquisition, optimal fitting of a reference cylinder, construction of a reference cylinder-assisted latitude and longitude positioning system, resampling of the reference cylinder's surface grid, unfolding the cylinder to a two-dimensional plane and completing pattern design, and point calculation for UAV spraying. This achieves precise projection transformation of the planar design pattern onto the structure's surface, providing industrial mathematical support for UAV spraying trajectory planning, attitude control, and parameter adjustment. This invention features high design accuracy, simple control logic, and good visual effects, effectively solving the problem of pattern deformation on curved surfaces of columnar or quasi-column structures. It is applicable to automated UAV spraying operations on various columnar or quasi-column structures such as TV towers, giant chimneys, angular TV towers, and water towers.

This invention belongs to the technical field of industrial control, and more specifically, relates to a data-driven modeling method based on DCS logic autonomous exploration. The method includes: collecting real-time data and preprocessing it, then calculating the time delay relationships of various influencing factors under different operating conditions; constructing a dictionary library, encapsulating the mathematical logic of basic algorithm blocks from the DCS algorithm block function library into basic units in the dictionary library, serving as the basic units for building the required model; using machine learning algorithms to train and explore mathematical model structures that match the dictionary library for various influencing factors and temperature changes; and executing deployment based on the DCS system and the generated mathematical model structure. This invention solves the problems that while neural network prediction models can make predictions, they cannot be directly converted into DCS logic execution structures; and that current mathematical modeling methods require manual selection of function structures, which cannot adapt to complex systems, often resulting in a disconnect from the DCS structure and hindering engineering implementation.
