The invention provides an optimization method based on depth Q-learning remote sensing data discretization, and the method comprises the steps: carrying out the feature extraction of a remote sensing image, obtaining a feature subset, carrying out the preprocessing of the feature subset, obtaining a candidate breakpoint set, carrying out the binary genetic coding of the candidate breakpoint set, and constructing a to-be-optimized discretization scheme; designing a state set of a crossing stage and a state set of a variation stage through the global search capability and the local search capability of a genetic operator; constructing a fitness function with a control variable, and constructing a self-adaptive reward function; a pair of depth Q-learning with the same structure is introduced to calculate the Q value in real time in the transition between the cross state and the variation state, and the cross fragment and the variation point of the discretization scheme to be optimized are determined. According to the method, a pair of depth Q-learning with the same structure is introduced into the discretization scheme to be optimized, so that the search efficiency of the feature discretization method based on the evolution model is improved, and the number of breakpoints can be further reduced while relatively high classification precision is obtained.

The utility model discloses a butt joint clamp tool for frame welding, which comprises a base, the upper end of the base is fixedly connected with a fixing plate, the side wall of one side of the fixing plate is fixedly connected with two symmetrically arranged fixing blocks, the two fixing blocks are jointly and rotatably connected with a rotating rod, and the rotating rod is fixedly connected with the base. The rotating rod located between the two fixing blocks is fixedly sleeved with a connecting block, the end, away from the fixing plate, of the connecting block is fixedly connected with an overturning plate, a through groove is formed in the base, and an overturning mechanism used for overturning the overturning plate is arranged in the through groove; the turnover mechanism comprises a moving plate slidably connected into the through groove, and two symmetrically-arranged racks are fixedly connected to the side wall of the moving plate. The turning mechanism is reasonable in structure, and can drive the rotating rod and the turning plate to turn during welding by arranging the turning mechanism, so that the angle between two workpieces can be adjusted, and welding at different included angles is facilitated.

The utility model discloses a glass is transported and is used sucking disc structure relates to glass sucking disc field, the utility model discloses a main support, the lower sides of main support are equipped with vice support through the hinge rotation installation, are used for the rotation contraction of two groups vice support, a plurality of sucking disc assemblies are installed with array on vice support, and the angle of two groups vice support is installed with support mechanism between, is used for stabilizing two groups vice support's angle, realizes the unfolding of two groups vice support, the utility model discloses a main support is connected with two sides vice support rotation through the hinge, makes two groups vice support and can be folded inwards and is contracted around the hinge axle, and the sucking disc assembly is folded and is gathered with vice support synchronously, and the overall structure volume is greatly reduced, has solved the difficult problem of transportation and storage of traditional fixed type sucking disc frame because of oversize, simultaneously, the support mechanism is locked vice support's unfolding angle through the linkage action of screw rod or connecting rod when unfolding, ensures the stability when glass adsorption.
