A device, method and system for measuring tree-ring micro-loss

Abstract

The invention discloses a device, method and system for measuring tree ring micro-damage. The device, method and system for measuring tree ring damage provided by the present invention are based on the characteristics of different densities of early wood and late wood. The resistance received by the drill is small, and the resistance to the drill is relatively large when it encounters late wood with high density. The alternating change of the resistance of the drill can reflect the characteristics of the internal annual rings of the wood. The motor that drives the drill to perform uniform spiral motion The annual rings of the object to be measured can be determined by the alternating change of the current, and there is basically no harm to the tree. It can be seen that the tree ring damage measurement device, method and system provided by the present invention can determine the tree rings in a minimally invasive state without harm to tree growth, and the device is compact in structure, light in weight, good in portability, and easy to work. efficient.

Description

technical field [0001] The invention relates to the field of forestry intelligent equipment, in particular to a device, method and system for measuring tree ring micro-damage. Background technique [0002] Tree rings have the advantages of accurate dating, strong continuity, high resolution and good recordability. In order to develop and utilize forestry resources rationally, the research on tree rings is of great significance. By analyzing the annual rings of standing trees, the age and growth status of trees can be judged, the growth trend can be predicted, and the basis for forest management can be provided. Annual rings provide reference data for many related disciplines, such as using the inherent information of annual rings to trace or reconstruct the historical process of natural environment evolution, applying to climate change research in historical periods, and using annual rings to identify ancient buildings and cultural relics , the age of ancient works of art,...

But to cut the discs, you need to cut down the trees to obtain the discs, which is very destructive to the trees and is not suitable for ancient trees and precious tree species. When sampling, you need chainsaws, machine oil, saw hands and other equipment, and it is difficult to transport the wood.

Drilling the wood core method is labor-saving, convenient for transportation, and easy to store. Generally, a tool such as a growth cone is needed for sampling. The diameter of the growth cone is generally 5.15mm, and the damage hole for living trees or old trees is relatively large. Drilling the sample wood core on the tree will cause great damage to the tree itself
