Walking type soil attribute hyperspectral rapid detection vehicle and method thereof

Abstract

The invention discloses a walking type soil attribute hyperspectral rapid detection vehicle and a method thereof. A connecting frame used for being connected with an external power dragging device is vertically fixed to the top of a dragging type suspension platform of the detection vehicle; a height adjusting mechanism and a four-connecting-rod profiling mechanism are arranged on the dragging type suspension platform, and a corrugated cutting disc, a ditching wheel, a spectrum probe furrow plough and a soil covering press wheel are sequentially mounted at the bottom of the dragging type suspension platform in the advancing direction of the power dragging device; a signal analyzer, a spatial position signal receiving antenna, a spatial position signal processing analyzer, a control platform and a power supply for supplying power to the power utilization device are arranged on the dragging type suspension platform, and the dragging type suspension platform is used for acquiring spatial position information, spectral information and soil attribute information of a target sampling point. The detection vehicle is hung at the rear end of a dragging power device, can rapidly detect hyperspectral data of soil along with the field operation process, and can realize real-time dynamic monitoring of certain attributes of the soil.

Description

technical field [0001] The invention belongs to the technical field of soil hyperspectral near-ground sensing, and in particular relates to a walking type soil attribute hyperspectral rapid detection vehicle and a method thereof. Background technique [0002] In my country's agricultural production, there are still problems such as excessive use of pesticides and fertilizers, which has also brought about a large number of economic and ecological problems such as waste of resources, soil compaction, and groundwater pollution. Using modern scientific means to find out the physical and chemical properties of soil, crop growth status and fertilizer requirements, and precisely control the input of various production factors can obtain the greatest production and ecological value. At the same time, the soil has a high degree of spatiotemporal heterogeneity, and various nutrients are constantly changing. In the past, the basic physical and chemical information of farmland soil was...

AI Technical Summary

Problems solved by technology

[0005] To sum up, there are currently many field soil property monitoring devices based on visible and near-infrared bands, but most of the devices have problems such as separation of sampling and measurement processes, and inability to cooperate with field operations, and there is still a lot of waste of manpower and material resources. At the same time, it also restricts the further improvement of the time and space accuracy of the data, and the walking soil property hyperspectral rapid detection vehicle combined with field cultivation can greatly make up for these shortcomings to achieve continuous, rapid and dynamic inversion detection of soil property information
