The present invention discloses an overcurrent protection method, an overcurrent protection circuit and a power supply using the same. A first signal representing an output voltage is obtained from a power supply, an overcurrent threshold signal is obtained according to the first signal, a second signal representing an output current is obtained from the power supply, an overcurrent protection signal is obtained according to the second signal and the overcurrent threshold signal. When the second signal is greater than the overcurrent threshold signal, it represents that the output current of the power supply is overcurrent, and the power supply performs overcurrent protection. The overcurrent threshold signal is equal to a first overcurrent threshold when the first signal is below a first reference value, and is less than the first overcurrent threshold when the first signal is greater than the first reference value.

The utility model relates to the technical field of landscaping, in particular to a landscaping sapling lateral bending prevention assisting and supporting device which comprises a shell assembly, a sliding sleeve and an improved assisting and supporting device are arranged on the outer portion of the shell assembly, and lateral bending of saplings can be prevented through cooperation of a two-way lead screw, a movable block and a guide block. When the lateral bending prevention assisting and supporting device for the landscaping saplings is used, the distance between the two C-shaped plates is adjusted according to the heights of the landscaping saplings, and the problem that different assisting and supporting devices need to be replaced when the landscaping saplings with different heights need to be clamped is solved; through cooperation of a sliding sleeve, a sliding column and a control rod, the height of the auxiliary supporting device can be adjusted according to the height of a landscaping sapling in the use period of the landscaping sapling lateral bending prevention auxiliary supporting device, and the problem that a traditional rod cannot be changed along with growth of the sapling is solved; therefore, the lateral-bending-prevention assisting and supporting requirements of the saplings for landscaping are met.

This application relates to the field of bridge safety monitoring technology, specifically to a method, device, and system for locating bridge damage areas. The method monitors bridge health using a parallel macro-micro dual-channel physical information neural network structure. The macro-channel generates global predicted physical field quantities based on global monitoring information through a fully connected neural network. The micro-channel, based on the global predicted physical field quantities output by the macro-channel, introduces a damage mechanics constitutive model to physically constrain the graph neural network, focusing on key component areas, identifying local physical inconsistencies, thereby locating local damage and quantifying uncertainty. This achieves decoupling from the environment / load-dominated response provided by the macro-channel, solving the problem in existing technologies where environmental changes mask changes caused by minor damage.
