Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of terrain simulation, and relates to a hydraulically driven lifting mechanism for terrain simulation; specifically, it relates to a control method for a terrain simulation device and a lifting mechanism for the terrain simulation device. Background Art
[0002] In the fields of geographic information systems, water conservancy projects, environmental simulation, etc., the simulation of real terrain environment is crucial. Most of the terrain physical models used for testing are first processed with materials such as wood boards, and then poured with cement concrete, which is time-consuming and labor-intensive. Once put into use, they are all single-purpose. Changing the terrain requires destroying the original one and re-customizing it. It costs a lot to reproduce it later. In addition, most of the existing terrain physical models use a fixed frame structure, and only one model can be built at a time. Changing the terrain or adjusting it requires destroying the original model and building it again. The cost of use is high and the function is single. Although some can simulate the terrain automatically, most of them are small in size and the simulation accuracy is not high, which cannot meet the needs of large-scale and high-precision terrain simulation. Moreover, most of the large-sized ones on the market are integrated, occupying a large area, and wasting land resources when left vacant.
[0003] At present, the existing automated terrain simulation is combined with 3D printing. Models of rivers and lakes are printed out according to terrain parameters and used after solidification. However, they are one-time and cannot be adjusted. Once the terrain needs to be changed, the original one needs to be dismantled and re-made, which also causes waste of materials.
