Device and method capable of accurately monitoring depth of accumulated snow in forest in real time

Abstract

The invention belongs to the technical field of accumulated snow depth measurement, and discloses a device and method for accurately monitoring the depth of forest accumulated snow in real time, and the device comprises a mounting frame, and a fine adjustment mechanism and a measurement mechanism which are arranged on the mounting frame; the fine adjustment mechanism is used for adjusting the horizontal state of the measuring mechanism and enabling the measuring mechanism to be parallel to the measured ground; the measuring mechanism comprises two infrared snow depth sensors which are symmetrically arranged, and the two infrared snow depth sensors can independently rotate; a camera which is arranged between the two infrared snow depth sensors and can move between the two infrared snow depth sensors in a reciprocating mode, and the moving direction of the camera is perpendicular to rotating shafts of the infrared snow depth sensors; in conclusion, when the infrared light spots formed by the two infrared snow depth sensors on the surface of accumulated snow coincide, snow depth calculation is executed, so that the whole snow depth monitoring is not affected by the sensor installation angle, and the snow depth monitoring precision is improved.

Description

technical field [0001] The invention belongs to the technical field of snow cover depth measurement, and in particular relates to a device and method capable of accurately and real-time monitoring of forest snow cover depth. Background technique [0002] At present, for the measurement of snow depth, the traditional method is to use a snow ruler or an ordinary meter stick to insert vertically into the snow to read the snow depth; but this measurement method is time-consuming and labor-intensive, and mainly depends on the subjective measurement of the staff , poor real-time performance. [0003] In addition, in the prior art, there are real-time measurement methods of directly obtaining snowfall depth through sensing instruments such as laser snow depth sensors and ultrasonic snow depth sensors. Although these methods have high real-time performance, they still have certain defects, such as: ultrasonic snow depth The sensor will be affected by factors such as wind speed, une...

[0003] In addition, in the prior art, there are real-time measurement methods of directly obtaining snowfall depth through sensing instruments such as laser snow depth sensors and ultrasonic snow depth sensors. Although these methods have high real-time performance, they still have certain defects, such as: ultrasonic snow depth The sensor will be affected by factors such as wind speed, uneven snow surface, low blowing snow, and lower temperature during measurement. The laser snow depth sensor will be affected by factors such as installation angle and measurement position during measurement, resulting in poor measurement accuracy. The problem
