Description

Technical Field

[0001] The utility model relates to a carbon sink monitoring device, in particular to a monitoring device for measuring the carbon sink of a tea garden. Background Art

[0002] Under the dual-carbon background of "carbon peak and carbon neutrality", the construction of low-carbon tea gardens has become one of the important strategies for ecological environment protection and the sustainable development of the tea industry. The construction of low-carbon tea gardens needs to be comprehensively considered from both industrial needs and environmental needs. The basic idea is to implement the development policy of "stabilizing the area, increasing the yield per unit, quality and efficiency", develop and promote advanced and applicable technologies that are resource-saving, environment-friendly and ecologically safe, and achieve the goal of increasing carbon sinks and reducing emissions while ensuring high-yield, high-quality, safe and efficient tea production, so as to ensure the sustainable and healthy development of the tea industry. How to maximize the carbon sink function of the tea garden while reducing greenhouse gas emissions in tea production is an important issue in the current transformation of low-carbon tea garden production technology and low-carbon tea production.

[0003] The carbon sink monitoring in the prior art has the following disadvantages:

[0004] 1. The measurement cost is high and mismeasurement is easy to occur. To obtain the carbon sink amount for each seedling in a fixed sample plot, the on-site measurement, photographing, labeling, registration, and calculation processes need to be completed, which requires professional investigators to conduct on-site measurements. Due to measurement errors, data entry and operation errors, the data may be inaccurate.

[0005] 2. The monitoring timeliness is poor and the data is static data. The dynamic changes of biomass carbon are monitored by means of regular sampling surveys, soil sample collection and analysis, and vegetation biomass estimation. Due to the large on-site investigation workload and high cost, the cost of conducting one survey is relatively high, and the monitoring timeliness is poor, making it impossible to accurately grasp the growth dynamics of trees, while the forest carbon sink is closely related to the growth of trees and changes dynamically. Summary of the Invention

[0033] The technical solution of the present utility model is as follows:

[0034] Please refer to Figure 1 As shown, a monitoring device for measuring tea garden carbon sink includes a support frame, a height gauge 1, a data collector, and a ground diameter measuring instrument 2. The support frame includes a column 3 and a base 4 at the bottom of the column 3; installation holes can be opened on the base 4, and the base is fixed to the ground through ground nails, or the base 4 can be directly buried in the soil. A cross arm 5 is provided on the column 3, and the height gauge 1 is installed on the cross arm 5. The data collector (not shown) is externally provided with a protective housing 6, and the protective housing 6 is installed on the column below the height gauge 1; the height gauge 1 is used to measure the canopy height of tea trees in the tea garden, and it is electrically connected or wirelessly communicatively connected to the data collector. The ground diameter measuring instrument 2 is used to measure the ground diameter of tea trees in the tea garden, and it is electrically connected or wirelessly communicatively connected to the data collector.

[0035] In a specific embodiment, the data collector can collect, store, and transmit data, and can also remotely transmit the processed data. For example, SQL Server 2008 data collector, Symbol PDT-1100 data collector, etc.

[0036] In a specific embodiment, the height gauge 1 and the cross arm 5 are rotatably connected to achieve measurement at various angles. For example, a conventional camera rotation structure is used to drive the height gauge 1 to rotate.

[0037] In a specific embodiment, the column 3 is a liftable column, which can adopt a manual lifting structure or an electric lifting structure. Through the lifting structure, the lifting of each device on the column can be realized, which is convenient for equipment maintenance and adjustment of the equipment height.

[0038] In a specific embodiment, a lightning protection mechanism 7 is provided at the top of the column 3.

[0039] In a specific embodiment, a solar power supply mechanism 8 is provided on the column for powering the device, or a power supply system can be additionally provided for power supply.

[0040] In a specific embodiment, the height gauge 1 is a laser rangefinder. The laser rangefinder is an electronic instrument that is widely used to measure the height of trees at present. It emits a laser beam and calculates the tree height by receiving the signal. High precision and fast and convenient are one of its advantages.

[0041] Furthermore, the ground diameter measuring instrument 2 is a digital display vernier caliper with built-in wireless data transmission, an excitation light ground diameter measuring instrument, or an infrared ground diameter measuring instrument.

[0042] In a specific embodiment, the ground diameter measuring instrument 2 is a digital display vernier caliper with built-in wireless data transmission, such as the digital display vernier caliper based on wireless data transmission in Patent CN212806797U. The measurement module is triggered wirelessly to obtain the current measurement data, improving the convenience of the vernier caliper when measuring larger workpieces.

[0043] In a specific embodiment, the ground diameter measuring instrument 2 is an infrared ground diameter measuring instrument, such as a ground diameter measuring instrument in Patent CN209459596U.

[0044] In a specific embodiment, as Figure 2 shown, the excitation light ground diameter measuring instrument 2 includes a U-shaped frame 21. The two parallel sides of the U-shaped frame 21 are respectively a laser emission end and a laser reception end. A laser emitter 22 is fixedly provided on the laser emission end. The width of the laser beam emitted by the laser emitter 22 in the horizontal direction is greater than the ground diameter D of the tea tree. A laser receiver 23 opposite to the laser emitter 22 is fixedly provided on the laser reception end, and the distance between the laser receiver 23 and the laser emitter 21 is greater than the ground diameter D of the tea tree. The U-shaped frame 21 is vertically fixed on the first support frame 24. By measuring the ground diameter of the tea tree without contact, the work efficiency is improved and the error caused by humans is reduced.

[0045] The laser receiver 23 includes a charge-coupled device (CCD) image sensor (not shown). The width of the charge-coupled device image sensor in the horizontal direction is greater than the ground diameter of the tea tree.

[0046] The laser receiver further includes a communication module (not shown). The communication module is electrically connected to the charge-coupled device image sensor and is used to output the image signal provided by the charge-coupled device image sensor to the data collector.

[0047] During specific operation, the U-shaped frame is brought close to the tree trunk, so that the laser emission end and the laser reception end are respectively located in front of and behind the tree trunk 100. Adjust the position so that the width of the laser beam emitted by the laser emitter 22 in the horizontal direction is greater than the ground diameter of the tea tree. The laser beam of the laser emitter 22 irradiates the tree trunk and forms a shadow on the receiver 23 ( Figure 3 ), and the distance of the shadow in the horizontal direction is the ground diameter D of the tea tree. As the tea tree grows and the ground diameter increases, but the measurement position remains unchanged. If the conventional contact excitation light measurement method is used, the ground diameter cannot be measured in real time.

[0048] Preferably, the first support frame 24 is a liftable structure, which is convenient for adjusting the height of the measuring instrument, so as to measure the ground diameter at a specific position. At the same time, it can adapt to the measurement of the ground diameters of more plants, improving the work efficiency.

[0049] Preferably, the bottom of the first support frame 24 is spiked and can be inserted into the soil for fixation.

[0050] The monitoring device for measuring the tea garden carbon sink of the present utility model can be connected to the Internet, and transmit the obtained tea tree ground diameter data and vegetation canopy height data to a remote terminal through a wireless network or a wired network. There is no need for the user to export data at the device end, and it is simple and fast to use. The measurement of the tea garden carbon sink refers to Patent CN 117219153 A, a method for constructing a model for estimating the underground biomass of Robinia pseudoacacia in a slope ecological restoration area. According to the relationship between the underground biomass (W), the ground diameter (D), and the tree height (H), an underground biomass estimation model is constructed.
