Embodiment 1

[0036] Please refer to figure 1 , figure 2 , image 3 and Figure 4 , this embodiment provides a soil flux measurement device for automatically switching between light and dark breathing chambers, which includes a carrier 1, a light intensity sensor 2 arranged in the carrier 1, a glass plate 11 arranged on the carrier 1, and a The film 12 on the glass plate 11 for adjusting the transparency, the top window 3 hinged with the top of the carrier 1, the side window 4 hinged with the side wall of the carrier 1, the first electric push rod 5 rotatably connected with the carrier 1 and The second electric push rod 6; the output shaft of the first electric push rod 5 is rotatably connected with the side window 4, and the output shaft of the second electric push rod 6 is rotatably connected with the top window 3; the glass plates on the side window 4 and the top window 3 The outer walls of 11 are provided with films 12 for adjusting the transparency.

[0037] In some embodiments of...

Embodiment 2

[0039] Please refer to figure 2 , this embodiment proposes based on the technical solution of Embodiment 1, the film 12 includes a first glass layer 121, a first conductive layer 122, a polymer dispersed liquid crystal layer 123, a second conductive layer 124 and a second glass layer 125 arranged in sequence; The first conductive layer 122 and the second conductive layer 124 are respectively connected to the thin film controller 82 .

[0040] In some embodiments of the present invention, for the application of the thin film 12, it is arranged on the glass plate 11, and it is specifically a SMART TINT thin film 12, which contains a layer of liquid crystal dimming film (PDLC) in the middle. The confused state realizes the requirements of the light and dark breathing room for transparent and blurred environments. A light intensity sensor 2 is arranged on the inner wall of the breathing chamber (the enclosed area enclosed by the carrier frame 1, the glass plate 11, the top windo...

Embodiment 3

[0042] Please refer to figure 1 , image 3 and Figure 4 , this embodiment is proposed based on the technical solution of Embodiment 1, and further includes a plurality of swing arms 41 , the output shaft of the first electric push rod 5 is rotatably connected with the side window 4 through the swing arm 41 ; the output shaft of the second electric push rod 6 The swing arm 41 is rotatably connected to the top window 3 .

[0043] In some embodiments of the present invention, the swing arm 41 is provided to more conveniently provide a longer torque for the first electric push rod 5 or the second electric push rod 6 during the movement of the top window 3 and the side window 4 , thereby reducing the force required for the top window 3 and the side window 4 to rotate, and improving the convenience.

Abstract

The invention provides soil flux measuring equipment and system capable of automatically switching light and shade breathing chambers, and relates to the technical field of soil measuring equipment. Comprising a bearing frame, a light intensity sensor, a glass plate arranged on the bearing frame, a film used for adjusting transparency, a transom window and a side window used for ventilation and a pushing electric pole used for pushing the transom window and the side window. And films for adjusting transparency are arranged on the outer walls of the glass plates on the side windows and the top window. The power supply supplies power to the upper computer, the serial port controller is connected with the upper computer, the soil temperature sensor, the soil humidity sensor and the air temperature sensor are connected with the soil temperature sensor, the light intensity sensor and the film controller are connected with the serial port controller, and the serial port controller is connected with the electric push rod. The problem of variability of small-scale spatial soil respiration can be solved, and control of influence of biological elements on dynamic change of soil respiration on different time scales is enhanced; and various data of the soil can be effectively detected.

Description

technical field [0001] The invention relates to the technical field of soil measurement equipment, in particular, to a soil flux measurement equipment and a system for automatically switching between light and dark breathing chambers. Background technique [0002] There are many factors affecting soil respiration, and the influencing factors are different in different ecosystems in different time and space. Studies have shown that soil temperature and humidity are the main factors affecting soil respiration. The establishment of a soil respiration model under the influence of soil temperature and humidity is more helpful to quantitatively describe soil respiration. However, when soil temperature and humidity are too high or too low There will still be large errors. [0003] Determining soil respiration rates and their temporal and spatial fluctuations in different terrestrial ecosystems is the most basic data for global carbon balance budgets and estimates of potential effe...
