Description
Technical Field
The invention relates to the technical field of tree annual ring detection, in particular to electric tightly-holding type tree annual ring micro-damage detection equipment and method.
Background
Tree growth rings are concentric rings on the cross section of a trunk and are formed due to seasonal climatic changes. The trees grow faster in spring and summer, and the corresponding growth rings are lighter in color and lower in density, so that the trees are called as early woods. The growth speed of trees in autumn and winter is slow, and the corresponding growth rings are dark in color and high in density, so that the trees are called as late woods. The tree growth ring detection is not only a main way for acquiring the growth and the age of the tree growth ring, but also an effective way for acquiring climate and environment transformation information, and is widely applied to the fields of forestry, climate, enviroment and the like.
At present, the modern technology for tree annual ring detection by a micro-damage or nondestructive means is gradually popularized. The annual ring detection technology represented by the micro-drilling resistance method has the advantages of high detection accuracy and small damage to trees. The annual ring micro-damage detection device developed based on the micro-drilling resistance method principle generally adopts a handheld operation mode, an operator aligns the annual ring micro-damage detector with a tree detection point through a holding handle on the device, then controls a micro drill point to drill into the tree through a button on the handle, when the micro drill point drills out from the other side of the tree, the acquisition of annual ring detection data is completed, then the micro drill point is operated through a manual control handle to withdraw from the original path on a drilling path, and the whole detection process is completed. In the whole detection process, an operator is required to hold the equipment all the time and keep the equipment fixed with the detected part of the tree without displacement. At the same time it is necessary to observe whether the micro drill bit has drilled out from the other end of the trunk, even if the drilling is stopped by the control handle and switched to the drill bit exit mode. Although this kind of equipment has realized the micro-damage detection of trees annual ring, still need further promotion in the aspect of the degree of automation of equipment, availability factor. Meanwhile, the existing micro-drill resistance method equipment generally adopts the arrangement of a sampling resistor, and the detection of the resistance change of the micro-drill point is realized through an analog/digital converter. Because the method uses analog signals for detection and transmission, the signal quality is poor, and the problems of high-frequency noise and line crosstalk exist, so that the detection accuracy is low, and the acquisition method of the detection signals still needs to be improved to improve the quality of the detection signals.

5. The electric clasping type tree ring micro-damage detection device as claimed in claim 4, wherein a photoelectric switch trigger piece is fixed on the upper end of the right jaw structure, and two groove-shaped photoelectric switches are arranged on the upper end of the bottom shell.
6. The electric clasping tree-ring micro-damage detection device as claimed in claim 1, wherein the installation cabin is composed of a metal shell arranged at left, bottom and right sides, a front end cover arranged at front side and a rear end cover arranged at rear side;
the front end cover is fixedly connected with the shell, and the micro drill point penetrates out of the front end cover.
7. The electric enclasping type tree ring micro-damage detection equipment according to claim 1, wherein a coupler is arranged between the enclasping motor and the bidirectional screw rod.
8. The electric clasping type tree growth ring micro-damage detection device as claimed in claim 1, wherein a drill point clamp is arranged between the micro drill point and the rotating motor.
9. A method for detecting micro-damage of an electric holding type tree ring is characterized by comprising the following steps:
s1: placing the tree trunk to be tested between the left holding claw and the right holding claw, pressing down the first control button, enabling the left holding claw and the right holding claw to gradually approach and close, and releasing the first control button after the left holding claw and the right holding claw contact the tree;
s2: pressing a third control button, enabling the micro-damage detection main body mechanism to enter a drilling detection state, propelling the motor to advance slowly, pushing the micro drill point rotating at a high speed to perform drilling detection, acquiring detection resistance data through a digital micro-damage resistance detection method, and sending the acquired detection resistance data to client software through a Bluetooth wireless transmission mode to be displayed in real time;
s3: when the micro drill point drills out from the other end of the trunk, the acquired detection resistance data are obviously reduced, the transmission of the detection data is completed, and the rotation directions of the propulsion motor and the rotating motor are reversed, so that the micro drill point exits from the tree to be detected according to the original path;
s4: after the micro drill point is withdrawn from the tree, the micro damage detection main body mechanism stops working, the third control button is pressed down to enable the left holding claw and the right holding claw to be far away from the opening, the electric holding mechanism is taken down, and single detection is completed.
10. The method for detecting the micro-damage of the annual rings of the electric clasping tree as claimed in claim 9, wherein the digital micro-damage resistance detection method comprises:
s01: acquiring the rotating speed of the rotating motor through an encoder;
s02: calculating a rotating speed error according to the current rotating speed and the target rotating speed;
s03: calculating the rotation speed error through a PID closed-loop control algorithm to obtain PWM opening time;
s04: and calculating the PWM duty ratio through the PWM opening time, and calculating the resistance borne by rotation according to the PWM opening time and the PWM duty ratio to realize digital micro-loss resistance detection.
