The invention relates to the technical field of electric power engineering construction, in particular to a disassembly and assembly construction planning method and system for an angle steel iron tower, electronic equipment and a medium. The method comprises the following steps: acquiring multi-source heterogeneous data in an angle iron tower construction scene and carrying out standardized preprocessing to obtain structured construction data; inputting the structured construction data into a field fine-tuning large model to execute a construction demand analysis operation, and generating a task decomposition list; performing resource scheduling and progress planning processing on the task decomposition list, and constructing a dynamic construction plan; and the linkage construction knowledge graph performs risk identification processing on the dynamic construction planning plan, and performs deviation analysis processing on the dynamic construction planning plan based on the current construction data to generate an adjustment suggestion. Through the mode, the technical problem that the accuracy and the real-time performance of a planning scheme are difficult to consider in the practical application of angle steel tower construction in the prior art is solved, and the scientificity, the reliability and the overall engineering benefit of construction planning are improved.

This invention relates to a drainage well system for a foundation pit suitable for a ground-mounted waterproof curtain. The system includes a drainage well body positioned within the backfill area of ​​the foundation pit, located between the main structural wall and the ground-mounted waterproof curtain. The drainage well bodies are arranged at predetermined intervals within the backfill area. The outer facade of the main structural wall is provided with a waterproof layer. Each drainage well body includes a non-porous solid pipe section and a perforated filter section located below the non-porous solid pipe section. The perforated filter section is externally covered with a filter layer, and the surrounding hollow spaces of the filter layer are filled with graded filter media. The lower end of the drainage well body is positioned below the bottom of the foundation pit and above the stable waterproof layer. A pumping system is installed within the drainage well body to promptly pump out seepage water from the foundation pit when the water level within the drainage well body rises to a preset level. The pumping system is connected to the municipal stormwater drainage network. This invention can serve as a long-term drainage facility and also enables water resource reuse.

The invention discloses a low-small-slow unmanned aerial vehicle target tracking method under space-time constraint. The method comprises the following steps: firstly, screening high-potential candidate targets in a first frame of a video through a multi-scale background dynamic query fusion perception detection module; then, a space-time optimization constraint module corrects a target position in combination with short-term and memory pool features, and cross-fragment association is realized; and the memory trajectory judgment module utilizes a PN tree and polynomial fitting to pre-judge target motion. And finally, the tracking module detects the current frame, and high-precision and high-robustness real-time tracking of the low, small and slow unmanned aerial vehicle is realized through feature purification and camera calibration.
