The invention provides a power distribution network frame multi-stage planning method considering multi-type source load evolution development, and the method comprises the steps: analyzing the spatial-temporal evolution characteristics of a multi-type distributed power supply and a multi-type load based on the source load data of a to-be-planned region, building a multi-type source load evolution development prediction model, and carrying out the prediction of the multi-type source load evolution development; generating a source load typical scene oriented to a plurality of continuous planning level years; based on the typical source load scene of each planning level year, obtaining a multi-stage weak link evaluation result; a power distribution network frame multi-stage planning model is further constructed and solved, and a power distribution network frame multi-stage planning scheme is obtained; wherein the construction of the power distribution network frame multi-stage planning model comprises the following steps: establishing a multi-objective function, and taking the total planning cost, the voltage deviation and the line load rate as optimization objectives; constructing constraint conditions including an operation constraint, a network topology constraint and a multi-stage cooperative constraint; and topology continuity and evolution rationality of the power distribution network frame in multi-stage planning are realized.

This invention discloses a deep learning-based method for detecting concrete structures, comprising the following steps: acquiring images or video frames from the same area to form an observation dataset; establishing a set of defect hypotheses and constructing evidence items; constructing an observation action primitive library; calculating scores and performing quality gating using an observation quality scoring network based on MobileNetV3-Small; obtaining candidate defect instances through coarse detection; generating candidate regions and type distributions and forming multi-view packages; generating observation sequences and determining trigger states under time budget and reshoot count budget constraints; inputting an improved DUSt3R and outputting a structured evidence package upon triggering; fusing the type distribution and evidence package to determine if the criteria are met and outputting the results; updating the observation sequence if the criteria are not met; generating evidence data packages and updating the primitive selection strategy. This invention improves detection reliability, measurement consistency, and result traceability, and is suitable for intelligent detection scenarios of concrete structure defects.
