Embodiment 1

[0031] refer to Figure 1 to Figure 3 , the present embodiment provides a tree diameter measuring device, comprising: a first ruler bar 101, a second ruler bar 102 and an operation box 104,

[0032] One end of the first ruler bar 101 is movably connected with one end of the second ruler bar 102 to form a V-shaped structure with an adjustable opening angle. From the device 406, measure the rotation angle of the first chi bar 101 and / or the second chi bar 102 by the angle measuring device 402, measure the distance between the distance measuring device 406 and the tree by the distance measuring device 406, and be provided with in the operation box 104 The data processing device obtains the measurement result of the diameter at breast height of the tree according to the rotation angle and the spacing.

[0033] The first ruler 101 and the second ruler 102 can be rotated. Trees are generally cylindrical. When a user needs to measure a tree, he holds the first ruler 101 and the seco...

Embodiment 2

[0057] refer to Figure 6 , present embodiment provides a kind of measuring method of diameter at breast height of tree, comprises steps:

[0058] Step 1, open the V-shaped structure of the measuring device, and keep the first ruler bar and the second ruler bar horizontal;

[0059] Step 2, rotate the first ruler and the second ruler, so that the first ruler and the second ruler are respectively tangent to the tree cylinder;

[0060] Step 3: Obtain the rotation angle of the first or second ruler and measure the distance between the junction of the first ruler and the second ruler and the tree, and obtain the diameter at breast height of the tree according to a preset formula.

[0061] In this embodiment, the measuring device is the measuring device provided in Embodiment 1. By using the above-mentioned distance measuring device, the measurement steps of the tree diameter at breast height are very simple and convenient, and the measurement of tree diameter at breast height can ...

Abstract

The invention provides a device and a method for measuring the breast height diameter of a tree. The measuring device comprises a first ruler bar, a second ruler bar and an operation box, wherein oneend of the first ruler bar is movably connected with one end of the second ruler bar to form a V-shaped structure with an adjustable opening angle; the tree is clamped in the V-shaped structure; an angle measuring device and a distance measuring device are arranged in the operation box; and a rotation angle of the first ruler bar and / or the second ruler bar is measured through the angle measuringdevice; the distance between the joint of the first ruler bar and the second ruler bar and the tree is measured through the distance measuring device; a data processing device is arranged in the operation box; and a measurement result of the breast height diameter of the tree is obtained according to the rotation angle and the distance. The device is simple in structure, convenient to carry and operate and capable of greatly improving the measuring work efficiency.

Description

technical field [0001] The invention relates to the technical field of agriculture and forestry, in particular to a measuring device and method for tree diameter at breast height. Background technique [0002] Tree diameter at breast height refers to the diameter of a tree at a distance of 1.3 meters from the ground. In the current forest resource inventory and forestry investigation and research, tree diameter at breast height is one of the most basic data. Traditional measurement tools are mainly girths or calipers, which need to be measured The operator wraps his hands around the trunk, which is laborious to operate, and the measurement range of the caliper is limited, which is not suitable for trees with large diameters. In addition, during the measurement process, it is necessary to manually record the data of each tree, and to measure the data of each tree in the entire forest. Classified statistics and analysis of measurement data is time-consuming and labor-intensive...
