This invention relates to the field of bookshelf technology, and more specifically discloses an adjustable shelf spacing library book anti-tipping storage bookshelf, including a bookshelf component. The bookshelf component includes a bookshelf body, with T-shaped grooves on both side walls of the bookshelf body. The bookshelf body is divided into a book placement layer and an adjustable top layer. Multiple arrays of moving components are slidably connected between the T-shaped grooves. A detection box and a control unit are fixedly connected to the outer side wall of the moving components. A monitor is fixedly connected to the outer side of the top wall of the bookshelf body. This invention, by including the bookshelf component, moving components, and detection box, facilitates the setting of an adjustable top layer and adopts a mechanism where the movement of one layer drives the linkage of all upper layers. Combined with timed center of gravity monitoring, it ensures a safety margin when adjusting the shelf spacing, achieving the optimal center of gravity position. When the center of gravity is too high, the lower layers are appropriately reduced to decrease the safety margin of the lower layers, effectively preventing the bookshelf from tipping over due to imbalance of the center of gravity.

The present application relates to the field of measurement switch control, and particularly relates to a power supply protection method and system for a measurement switch, which comprises: collecting multi-dimensional electrical quantity data of each node in a power distribution network within a preset time period at a fixed frequency and preprocessing; improving a cost function in a path search algorithm; searching for an optimal path node sequence from a power supply point to a target load point in the power distribution network based on the improved cost function, and generating a control instruction of the measurement switch according to the optimal path node sequence to control closing or opening of the corresponding switch. The present application fuses three core elements of a node's own abnormality degree, inter-node propagation correlation degree and local risk trend of path extension, guides the search algorithm to avoid nodes with obvious abnormality, and actively cuts off electrical channels with high abnormal propagation risk, thereby greatly reducing the probability of causing chain faults or safety accidents in the fault recovery process.
