Problems solved by technology

This method not only wastes a lot of measurement and setting time, but also wastes a lot of material
For this kind of precise physical model, the precise shape, position and level height are the difficulties in making, and the frequent use and replacement increases the difficulty of this measurement and setting, and the waste of materials greatly increases the cost of the experiment
Using the existing method of making physical models to simulate hydrology, water resources, and terrain evolution, the only way to reduce costs and improve efficiency is to reduce the division of regions and increase the ratio of the model to the actual terrain. The result is that the accuracy of the experimental simulation is reduced. Spend

Embodiment 1

[0025] This embodiment is a fast building system for physical models, the system block diagram is as follows figure 1 As shown, the structure is as figure 2 shown. This embodiment includes: an array of lifting columns 2 , a terrain information acquisition device 3 is arranged above the array of lifting columns, and the array of lifting columns and the terrain acquisition device are electrically connected to the computer control subsystem 1 . The array of lifting columns is composed of lifting columns densely arranged horizontally and vertically on the horizontal plane and the underlying surface of the model covered on the lifting columns 4 (see image 3 ). The lifting column includes: a lifting base 201 fixed on a horizontal plane whose lifting height is controlled by the lifting column array control unit, and a lifting block 202 is arranged on the top of the lifting base. When all the lifting blocks are lifted to the same plane, a A grid plane of tightly packed lifting bl...

Embodiment 2

[0036] This embodiment is an improvement of Embodiment 1, and it is a refinement of the terrain information collection device in Embodiment 1, such as figure 2 shown. The terrain information collection device described in this embodiment includes: a guide rail 303 installed directly above the lifting column array, a slider 301 driven by a motor to slide on the guide rail is hoisted on the guide rail, and all The laser probe 302 of the three-dimensional laser terrain scanner; the laser probe and the motor on the slider are connected to the terrain information acquisition controller, and the terrain information acquisition controller is checked and matched with the terrain information and the visual display unit connect.

Embodiment 3

[0038] This embodiment is an improvement of the above embodiment, and is a refinement of the above embodiment regarding the lifting column. The lifting column described in this embodiment is an electric spiral lifting column driven by a motor.

[0039] The electric screw lifting column is a mechanical transmission mechanism that uses a motor to drive a nut or a screw (screw lifting column) to generate relative motion between the nut and the screw. The motor used as power can be an ordinary motor, or a stepper motor and a servo motor. Which motor to use mainly depends on which control method is used.

[0040] If an open-loop control method is used, a stepper motor or a servo motor can be used to cooperate with the sensor at the end of the screw, that is, the sensor is set at the two extreme positions of the screw (spiral lifting column) to perform precise lifting control. For example, taking the lowest point as the starting point, since the number of rotations of the stepping...

Abstract

The invention relates to a system and a method for quickly building a physical model. The system comprises a lifting column array and a terrain information acquisition device, wherein the lifting column array and the terrain information acquisition device are electrically connected with a computer control sub-system; the lifting column array consists of lifting columns which are horizontally and longitudinally arrayed in a dense mode on the horizontal plane and a model lower cushion surface which covers the lifting columns; the computer control sub-system comprises a terrain database, a scale conversion unit, a physical model chassis height computation unit, a terrain information checking and visual display unit and a lifting column array control unit. The lifting columns which are densely arrayed are used, and the digital terrain information is combined with the lifting columns, so that accurate positions and accurate heights of the terrain elements are quickly determined; the physical model in an simulation test of hydrology and water resources and terrain evolution is economically and quickly built; and the physical model simulation test which is low in cost and obtains relatively accurate experiment data becomes a feasible option.

technical field [0001] The invention relates to a system and method for quickly building a physical model, which is a physical model modeling system and method for simulating topography and different underlying surfaces, and a machine for quickly establishing topography and topography and underlying surfaces in a simulated area. - Electronic systems and methods. Background technique [0002] To carry out simulation experiments of hydrology and water resources, topography and landform evolution at different scales (basin, regional or local scale), it is necessary to establish large-scale and very accurate topography and landform simulation models of different scales according to the purpose of the experiment. This scale model cannot be schematic, and the scale size must be determined strictly according to the research purpose and scale conversion rules. All geographical and geological elements representing topography and underlying surface in the scale model must have very p...
