The application relates to the technical field of direct-current power supply, and discloses a method for intelligently identifying and dynamically distributing power of a direct-current load. The method synchronously collects voltage and current waveforms when the load is connected, extracts transient and steady-state characteristics to construct a characteristic identifier, and compares the characteristic identifier with a pre-stored characteristic library to determine the load type or mark the load as a new type; according to the determination result, a corresponding power distribution strategy is executed, and the efficiency and state matching degree indexes are continuously monitored during the strategy execution process, so that re-identification based on new data and dynamic adjustment of the strategy are triggered, forming a closed loop. The application can accurately identify unknown or dynamically changing direct-current loads, realize adaptive power distribution and online optimization, and help improve the compatibility, energy efficiency and operation stability of a power supply system.

This invention relates to the fields of functional materials and intelligent sensing technology, and discloses a method for intuitively visualizing the stretching amount of a flexible adhesive. The method includes: providing a flexible adhesive with an elastic substrate capable of elastic deformation along the stretching direction; setting multiple patterned marking regions corresponding to different preset stretching thresholds on the surface of the elastic substrate; forming microgroove structures with differentiated structural parameters at corresponding positions on the elastic substrate to generate a differentiated stress concentration effect; forming color-developing layers containing mechanochromic materials with different bulk crosslinking densities in each patterned marking region, with each color-developing layer collectively constituting a patterned color-developing functional layer; through the synergistic effect of the differentiated stress concentration effect of the microgroove structure and the difference in bulk crosslinking density of the color-developing layers, each patterned marking region changes from a hidden state to a visible state when the corresponding stretching threshold is reached, thereby characterizing the stretching amount of the flexible adhesive through pattern visualization. This invention provides clear thresholds and high readability, and is suitable for scenarios such as motion protection, flexible electronics, intelligent packaging, and structural condition early warning.
