Description
Technical Field
The invention belongs to the technical field of water and soil conservation research devices, relates to a landform instrument host based on an integrated mainboard, and provides a device capable of dynamically observing three-dimensional landforms in real time.
Background
Due to the complexity of soil erosion phenomena, reliable methods are sought in research to observe and analyze erosion landforms so as to obtain the occurrence mechanism of the erosion landforms. The comprehensive observation method for soil erosion at home and abroad can be summarized into a post-rain investigation method and a dynamic rain observation method. The post-rain investigation method is a method for reversely deducing the water and soil loss amount by investigating the landform characteristics after rainfall. The intervention of non-contact measuring methods such as a laser scanner and the like makes the monitoring of the high-risk terrain in the gravity erosion field possible. However, during the current rainfall or after the first few rains, a part of the falling avalanche is washed away by the water flow, or a part of the soil input from the upstream is deposited in the avalanche, thereby causing an observation error. The dynamic observation method in rain is to comprehensively judge the type of soil erosion and the erosion amount thereof by continuously observing the erosion occurrence process and the erosion accumulation form in the soil erosion event occurrence process. The method can monitor the soil occurrence process, but the implementation difficulty is high, and the related research results are few. The first inventor of this patent and his team developed a three-dimensional landform dynamic observation instrument, a landform instrument, using structured light technology. The team is developed from 2009, 5 generations of landform instrument models are successfully developed so far, 6 issued national invention patents (ZL201310422836.6, ZL201310422447.3, ZL201010502055.4, ZL201010502051.6, ZL201010144689.7 and ZL201010144655.8) are obtained, and quantitative and dynamic observation of the trench slope gravity erosion process in the rainfall simulation test is realized. For example, the observation of the dam break scouring amount in the model test of the national science foundation key project (5139003) hosted by professor hongwu and the gravity erosion observation of the related test of the national science foundation project (51079016; 51179021) hosted by the first inventor of the patent are realized by adopting the geomorphology instrument observation device and the geomorphology instrument observation method.
However, the above geomorphology instrument still has the following disadvantages: (1) if the landform instrument host computer at the test site is moved, the position, the angle of a straight line type laser module in the host computer can change, the equidistance that the landform instrument host computer sent, parallel laser altitude face can produce great error promptly. Therefore, after the position and the angle of the linear laser module in the host computer need to be calibrated, the host computer can be repositioned and used for experimental observation, and the calibration work of the landform instrument is more complicated and time-consuming. (2) Because the height of the landform instrument is determined by different observation range requirements of the test, a certain height of the landform instrument cannot simultaneously meet the observation requirements of the plurality of tests. Aiming at the problems, the original landform instrument host is upgraded and reformed, the landform instrument host which accurately positions the linear laser module by utilizing the U-shaped card and is based on the integrated main board is redesigned, and the higher precision can still be kept under the condition that the landform instrument host is moved; and a sectional type landform instrument host is designed to adapt to the height change of a test range and realize the real-time observation of different test range requirements.
