This invention discloses a deep learning-based method for ultra-short-term photovoltaic (PV) power prediction. First, historical data is preprocessed to eliminate irrelevant variables and accelerate model training. Then, the advantages of three clustering algorithms are combined to obtain a more reasonable dataset partitioning. Next, particle swarm optimization is used to optimize the parameters of variational mode decomposition. Finally, parallel learning of CNN and GRU networks is employed to identify local and temporal features of the data, enabling the network structure to fully leverage the input data. Finally, a deeper learning process is achieved through CNN neural network concatenation and fusion, resulting in high-precision prediction. The PV power prediction method of this invention demonstrates excellent performance, significantly outperforming other traditional models in predicting PV power under different weather conditions.

The application provides a target detection method based on clustering optimization, which comprises the following steps: receiving target point cloud data, wherein the target point cloud data corresponds to a target image, and the target point cloud data is point cloud data of a predetermined region obtained by a laser radar, and the predetermined region is a region spaced apart from a vehicle by a predetermined distance; performing filtering processing and clustering processing on the target point cloud data to obtain a plurality of clustering results, and performing merging processing on the plurality of clustering results to obtain at least one target independent region; determining the size of a target voxel based on at least the at least one target independent region, and constructing a target pseudo image based on the size of the target voxel, and performing target detection based on the target pseudo image. In this way, the division of the target voxel is reasonable, thereby solving the problem that the division of the voxel is unreasonable in the prior art.

This invention discloses a cable tensioning device, method, and application for large-angle vertical rotation of long linear structures, belonging to the technical field of installation devices for large-angle vertical rotation of long linear structures. Located at the cable anchorage end of the higher part of the vertical rotation component, it includes a cable force identification module, a mechanical transmission module, and a tensioning module. The cable force identification module includes several force measuring elements, each disposed on each strand of the cable. The mechanical transmission module includes a three-stage rotating hinge structure, comprising a first rotating hinge structure, a second rotating hinge structure, and a third rotating hinge structure connected sequentially. This technical solution addresses the problem in existing technologies where, during large-angle vertical rotation of long linear structures, individual strands in the cable may become slack, and the limitation of the installation component's length and installation height makes it difficult to tension the slack strands.
