This invention discloses a crane safety operation control system and method based on machine vision and energy optimization management, belonging to the field of crane safety operation technology. Based on visual acquisition, this invention performs pre-operation benchmark calibration and dynamic data capture during operation, achieving full-cycle data traceability and synchronization based on timestamps. This clarifies the safety boundaries of the operation area and the initial state of the equipment, avoiding deviations and lags caused by data asynchrony, and ensuring the overall process is consistent and reliable. Visual data preprocessing eliminates external interference, and precise feature data is output using a safety benchmark model. Coupled with a tiered early warning mechanism, it accurately predicts operational anomalies and the risk of live intrusion and responds accordingly, achieving layered control of safety risks. By aligning visual data and operating parameters with timestamps to generate a fused dataset, and outputting safety levels and corresponding control signals through quantitative scoring, the objectivity and relevance of the assessment are improved, ensuring precise matching between control actions and safety states.

This invention relates to the field of management technology and discloses a method and system for generating management suggestions for long-term, low-maintenance mixed flower borders. The method includes: acquiring plant growth data and community succession data based on the spatial distribution characteristics of the sample plot, plant growth morphology characteristics, and environmental characteristics during the flower border's growth cycle; extracting characteristic data on plant morphology, growth rhythm, and tolerance performance; classifying all plant feature vectors based on a decision tree model; determining distance parameters between different plant combinations based on the K-nearest neighbor algorithm and judging the stability trend and substitution relationship of each plant combination; analyzing the vertical hierarchy, coverage relationship, and color coordination relationship of plants based on the plant combination structure; determining the association results between the community discrimination results and the flower border structure layout based on an association rule algorithm; and determining management suggestions based on the association results and a planning suggestion model. This invention ensures the reliability of mixed flower border management.

The application discloses an environment-friendly antibacterial blended yarn and a preparation method thereof. Raw materials of the blended yarn include natural plant fibers and modified modal fibers in a mass ratio of (65-70):(30-35); and the modified modal fibers are grafted with phenolic chitosan on surfaces. The natural plant fibers and the modified modal fibers are both green and environment-friendly fiber products. The natural plant fibers can provide part of antibacterial performance. The modified modal fibers have high dry and wet strength, and can compensate for the insufficient strength of the natural plant fibers. The obtained blended yarn has excellent strength and certain antibacterial property. Meanwhile, the modified modal fibers are grafted with phenolic chitosan on surfaces. The chitosan has excellent antibacterial performance, and the phenolic group can improve the poor cohesion between the natural plant fibers, so that the natural plant fibers and the modified modal fibers can be tightly combined together. The dry and wet strength and the antibacterial property of the obtained blended yarn are obviously improved.
