2results about How to "Optimize calculation method" patented technology

The present application relates to the technical field of industrial automation plate positioning, and specifically relates to a method for acquiring a six-point clamping jaw fixing point of a general rigid plate, which comprises the following steps: (1) configuring a file and importing a standard DXF file containing a graph, analyzing and acquiring a processing graph; determining whether the processing graph is connected at the beginning and the end and closed; if yes, the next step is entered; (2) determining whether the processing graph is legal; if yes, a limiting position is drawn, and a calculation auxiliary line is generated for user dragging; (3) segmenting the legal processing graph, and acquiring graph data after segmentation; after the graph data after segmentation is offset and expanded outward according to the radius of a positioning clamp or a positioning wheel, a round corner compensation is performed, a moving path of the positioning clamp or the positioning wheel is obtained, an auxiliary line that can be moved by a user is generated, and a positioning point is determined. The method can realize high-precision, simple operation, strong universality and intuitive calculation process of plate positioning for supporting complex special-shaped plates.

This invention provides a pumping device and a method for calculating the permeability coefficient. The pumping device includes a packing system, a pumping control system, a sealing system, and an observation system. The packing system includes an upper packer, a lower packer, and a packer pressurization device. The pumping control system includes terminal equipment and a variable frequency pump. The outlet of the variable frequency pump is connected to the ground via an outlet pipe. The sealing system includes a lower conversion chamber, an upper conversion chamber, a connecting pipe, and a sealing device. The observation system is used to collect first pressure data of the test layer, second pressure data of the upper part of the test layer, and flow rate data of the outlet pipe. The test layer is located between the upper and lower packers. The terminal equipment is connected to the observation system and the variable frequency pump, respectively, and is used to control the variable frequency pump to pump water based on the first pressure data and to calculate the permeability coefficient based on the relevant data. This invention is applicable to multi-layer aquifer testing and improves the accuracy of permeability coefficient calculation.
