This invention relates to the field of vibration control and health monitoring technology for civil engineering structures, specifically to an integrated device and control method for damping and vibration-induced de-icing of cable structures. This application achieves intelligent de-icing through a single device that combines damping vibration suppression with visual guidance, possessing a complete closed-loop control capability encompassing perception, decision-making, execution, and verification. It employs a progressive high-order modal excitation strategy, utilizing the complex local deformation of high-order modes to more effectively break down ice layer adhesion, fundamentally solving the industry problem of poor low-order modal excitation performance. Furthermore, the system can automatically select and upgrade the optimal mode according to different icing conditions, achieving online optimization of the de-icing strategy.

The application relates to the technical field of fertilizer control, and particularly discloses a corn variable fertilization control method and system for soda saline-alkali soil, which comprises the following steps: acquiring a regional map of a saline-alkali region, and counting fertilization components based on the regional map; determining detection points based on the positions of fertilization nozzles, acquiring soil parameters based on the detection points, and generating control instructions according to the soil parameters; performing space-time analysis on the acquired soil parameters, determining the correlation degrees of different detection points, and determining the mapping relationship between two soil parameters when the correlation degrees reach preset correlation degree thresholds; and recursively adjusting the soil parameter acquisition process of the detection points based on the correlation degrees; the application can simultaneously respond to the changes of rhizosphere alkalinity and sodium salt stress, significantly improve the nitrogen fertilizer utilization rate, reduce the ammonia volatilization loss, and effectively relieve the double stress of high pH and high SAR of the soda saline-alkali soil on the corn root system.
