Description

Technical Field

[0001] The invention relates to the technical field of moisture detection devices, and in particular to a moisture detection device based on hyperspectral remote sensing. Background Art

[0002] Hyperspectral remote sensing technology is an emerging remote sensing technology with the characteristics of high spatial resolution, rich spectral information, narrow and continuous band, and good timeliness. With the continuous development of technology, hyperspectral remote sensing technology has been widely used in many fields, including agriculture, environment, geology, etc. In the agricultural field, hyperspectral remote sensing technology is used to monitor crop growth, moisture content, pests and diseases, etc.

[0003] At present, when the moisture detection device of the hyperspectral remote sensing in the prior art detects the moisture content of the detection object, first, the object to be detected is properly placed in a special detection placement box; then, the detection head in the device is started to emit hyperspectral light to penetrate or reflect on the detection object, and then the moisture content of the object is scientifically measured. In this process, when the detection object is placed in the detection placement box, it is often difficult to maintain a flat state. The unevenness of this state will directly affect the accurate detection of the detection object. Specifically, the uneven surface may produce shadow areas or scattering of reflected light. These phenomena will interfere with the spectrometer's accurate capture and analysis of moisture characteristic bands, thereby reducing the accuracy and stability of the entire detection process.

[0020] The present invention provides a moisture detection device based on hyperspectral remote sensing. It has the following beneficial effects:

[0021] (1) The moisture detection device based on hyperspectral remote sensing uses an auxiliary flattening mechanism to enable the output shaft of the motor to drive the rotating seat to rotate, and the rotating wheel moves in the annular groove. In the process of passing through the hemispherical block, the rotating seat will move up and down, thereby causing the detection object in the detection placement box to shake, assisting in placing the detection object in the detection placement box flat, and improving subsequent detection results.

The arc-shaped protrusion 267 is slidably connected in the guide groove 242. An electric baffle 271 is provided on the side of the detection placement box 27 close to the collection box 29. The inner wall of the detection placement box 27 close to the collection box 29 is inclined. By rotating the rotating rod 262, the screw rod 261 is rotated, and then the threaded block 263 is driven to move, so that the support rod 264 moves, and the detection placement box 27 is in a tilted state, and then the electric baffle 271 is started to open, so that the detection object can be discharged from the detection placement box 27 to the collection box 29.

[0040] Furthermore, after the test object is discharged from the test placement box 27, the heating wire 28 can be started to heat, so as to dry the residual moisture in the test placement box 27 to prevent affecting subsequent tests.

[0041] In the embodiment of the present invention, in order to assist in drying the residual moisture in the detection placement box 27, specifically, the auxiliary drying mechanism 5 includes a limit sleeve 51, a vertical rod 52 is fixedly connected to the lower side of the limit sleeve 51, a gas cylinder 53 is fixedly connected to the bottom of the vertical rod 52, a one-way air inlet 54 and a one-way air outlet 55 are opened on the outer wall of the gas cylinder 53, a piston of the gas cylinder 53 is connected to a piston rod 56, and a connecting rod 58 is hinged at the bottom end of the piston rod 56, and the connecting rod 58 is away from the piston rod 56. One end of the cross bar 59 is hinged, and the end of the cross bar 59 away from the connecting rod 58 is fixedly connected to the cross plate 510. The upper side of the testing platform 1 is fixedly connected to a fixed plate 512, which is penetrated by the cross bar 59 and is slidably connected to the cross bar 59.

The cross plate 510 is pressed to move in the direction of the fixed plate 512, and the cross bar 59 drives the piston rod 56 to move. When the detection placement box 27 is in a tilted state, the rotating seat 24 rotates, and the arc-shaped protrusion 267 squeezes the cross plate 510 to move in the direction of the fixed plate 512. The cross bar 59 drives the connecting rod 58 to move, and then drives the piston rod 56 to move.

The round rod 571 is fixedly connected to the outer wall of the piston rod 56, and the spoiler plate 573 is hinged to the outer wall of the air cylinder 53. During the up and down movement of the piston rod 56, the round rod 571 can be driven to move, and then the straight rod 572 can be driven to move, so that the spoiler plate 573 swings, thereby further improving the drying effect of the detection placement box 27.

After the test is completed, the screw rod 261 is rotated by rotating the rotating rod 262, and then the threaded block 263 is driven to move, so that the support rod 264 moves, and then the test placement box 27 is in a tilted state, and then the electric baffle 271 is started to open, so that the test object can be discharged from the test placement box 27 to the collection box 29, and the heating wire 28 is started to heat, so that the residual moisture in the test placement box 27 can be dried;

[0045] At the same time, in the process of detecting the tilt of the placement box 27, the output shaft of the starter motor 25 rotates, the rotating seat 24 rotates, the arc-shaped protrusion 267 squeezes the cross plate 510 to move in the direction of the fixed plate 512, the cross bar 59 drives the connecting rod 58 to move, and then drives the piston rod 56 to move. In the process of the piston rod 56 moving downward, the air cylinder 53 can inhale external air through the one-way air inlet 54, and in the process of the piston rod 56 moving upward, the gas in the air cylinder 53 can be ejected through the one-way air outlet 55, to assist in detecting the drying of the placement box 27;
