Through the arrangement of the connecting mechanism, the sealing block is tightly attached to the first connecting piece and the second connecting piece, the gap between the door plate and the door frame is filled with the sealing gasket, the gap at the hinge connecting position is blocked through elastic deformation of rubber, and dust is prevented from entering a cab; lubricating grease is injected into the second sliding groove through the groove opening, the grease can flow to the first sliding groove along the sliding grooves to cover the surfaces of the first sliding block, the second sliding block and the connecting column, friction between parts can be reduced, abrasion is reduced, the hinge is prevented from rusting, and the problems of abnormal sound and blocking during door opening and closing are solved.

The invention belongs to the technical field of unmanned aerial vehicle image instant return methods, and particularly relates to a network and task dual-driven unmanned aerial vehicle image instant return method in a complex environment, which comprises the following steps of: acquiring four network index data of bandwidth, delay, jitter and packet loss rate, performing exponential weighted moving average filtering and denoising, and performing weighted calculation to obtain a network comprehensive quality score; five discrete network state levels are mapped, and a lagging threshold value is set for level switching; dividing an original image layer, a standard image layer and a thumbnail layer, setting a compression ratio according to a task type, determining the number of slices of each layer according to a corresponding rule to ensure that tile data volumes are consistent, and establishing association of tiles of different image layers by adopting a numbering rule; the comprehensive priority of image tiles is calculated based on four factors of a current viewport, user interaction, points of interest and a flight route, a priority queue jumping strategy is adopted, a network state level and a task type are combined, a to-be-transmitted image layer, the number of concurrent threads and a preloading strategy are dynamically adjusted, and instant image returning is achieved.

This invention relates to a method and system for visualizing a bridge BIM model. Specifically, the method involves acquiring a bridge BIM model, calculating the folding cost and the degree of local optimization after folding for each edge, sorting the edges according to the folding cost and the degree of local optimization, and placing them into a priority queue. Edges are then sequentially removed from the priority queue, and topology and boundary preservation checks are performed. If the checks pass, the two vertices of the removed edge are merged into a new vertex, and the folding cost and the degree of local optimization after folding for the affected edge are updated; otherwise, the removed edge is skipped. The simplified BIM model is divided into multiple components, and a starting triangle is determined from each component based on the normal vector of the triangle neighborhood in the component. The component is compressed using the starting triangle and then sent to a mobile device. The mobile device decompresses and renders the BIM model.
