Abstract

The present invention belongs to the technical field of water and soil conservation research devices and relates to an integrated mainboard-based geomorphology detector console, which is a device capable of achieving three-dimensional geomorphology dynamic detection in real time. A U-shaped clamp is used to accurately position linear laser modules so that parallel and equally-spaced laser contour planes are emitted and projected onto terrains to be detected, which are required by tests; the U-shaped clamp can determine the fixed positions of the laser modules on a mainboard, thereby achieving convenient adjustment of the emitting angle of the laser modules and the spacing between neighboring laser modules, and also ensuring relatively high precision of the position and angle of the laser modules under the condition that the geomorphology detector console is moved. On the basis of random assembly of a plurality of segmented units, real-time detection under different test range requirements can be implemented. The present invention relates to a novel geomorphology detector console which can conveniently and accurately fix the spacing and the emitting angle of the laser modules and satisfy different range and height requirements of detection.

Description

Geomorphology host based on integrated motherboard

Technical field

The invention belongs to the technical field of soil and water conservation research devices, and relates to a geomorphology host based on an integrated main board, which is a device capable of real-time dynamic observation of three-dimensional geomorphology.

Background technique

Due to the complexity of soil erosion, more reliable methods are used to observe and analyze eroded landforms in order to obtain the mechanism of occurrence. Looking at the observation methods of soil erosion at home and abroad, it can be summarized into two methods: post-rain survey method and rain dynamic observation method. The post-rainfall survey method is a method for inferring the amount of soil erosion by investigating the landform characteristics after rainfall. The intervention of non-contact measurement methods such as laser scanners makes it possible to monitor high-risk terrain on the site of gravity erosion. However, during the current rainfall or after several previous rains, some of the falling slumps have been washed away by water flow, or part of the soil input from the upstream will be deposited in the slumps, resulting in observation errors. The dynamic observation method in the rain refers to comprehensively judging the type and amount of soil erosion by continuously observing the erosion occurrence process and the shape of the erosion accumulation body during the occurrence of the soil erosion event. This method can monitor the process of soil occurrence, but it is very difficult to implement and few related research results. The first inventor of this patent and his team used structured light technology to develop a three-dimensional topography dynamic observation instrument-a topography instrument. The team has been developing since 2009. So far, it has successfully developed a 5th generation geomorphology prototype and obtained 6 authorized national invention patents (ZL201310422836.6; ZL201310422447.3; ZL201010502055.4; ZL201010502051.6; ZL201010144689.7; ZL201010144655.8 ), To achieve quantitative and dynamic observation of the gravity erosion process of the ditch slope in the rainfall simulation test. For example, the observation of the amount of dam erosion in the model test of the National Natural Science Foundation of China key project (5139003) chaired by Professor Zhang Hongwu and the gravity erosion observation of the relevant test of the National Natural Science Foundation of China (51079016; 51179021) chaired by the first inventor of this patent. All are realized by using the above-mentioned geomorphological observation device and method.

However, the above geomorphometer still has the following shortcomings: (1) If the geomorphological host at the test site is moved, the position and angle of the inline laser module in the host may change, that is, the equidistant , Parallel laser and other high-level surfaces will produce large errors. Therefore, it is necessary to calibrate the position and angle of the inline laser module in the host computer before the host computer can be repositioned for test observation. The calibration work of the above geomorphology instrument is more tedious and time-consuming. (2) The requirements of different observation ranges of the experiment determine the height of the geomorphology instrument, but a certain height of the geomorphology instrument can not meet the needs of multiple experimental observations at the same time. In response to the above problems, the present invention upgrades and transforms the original geomorphological host, and redesigns the geomorphological host based on the integrated motherboard that uses the U-shaped card to accurately position the inline laser module, and realizes the When the main unit of the instrument is moved, it can still maintain high accuracy; and the main unit of the segmented geomorphometer is designed to adapt to the change of the height of the test range and realize the real-time observation of the needs of different test ranges.
