Problems solved by technology

At present, in terms of eliminating hidden dangers of urban greening trees, some domestic researchers mainly use sound velocity, amplitude and frequency methods to detect internal defects and their positions in wood, but none of the detection instruments they use are dedicated to ultrasonic detection of trees. The corresponding relationship between the ultrasonic A-type wave and the defect displayed at the time is not obvious. Only a professionally trained person can judge whether there is a defect in the wood through the A-type wave, and the practicability is limited.

Embodiment Construction

[0016] exist figure 1 In this paper, the first is the design of the ultrasonic image reconstruction module and the design of the feature recognition function module, and then put forward the requirements for the design of the portable ultrasonic CT testing instrument, and design the testing instrument according to the specific requirements.

[0017] exist figure 2 In the control panel shown, using a well-designed man-machine dialogue interface is an important part of practical transformation. The menu is divided into 5 categories: basic, calibration, parameter, detection and function. The basic function includes 5 submenus of transmitting, receiving, probe, display and area. The calibration function includes 3 submenus of delay, probe K value and sound velocity. The parameter function includes Gate 1, Gate 2, Workpiece and System submenus. The detection function includes submenus of curve correction and defect height. Function This function contains Envelope, DAC Curve a...

Abstract

The invention discloses a portable bidimensional ultrasonic computed tomography (CT) non-destructive detector for urban trees. The detector is designed by adopting a modern electronic technology and a computer imaging and characteristic identification technology; and many potential safety hazards caused by sudden toppling and fall of the trees can be eliminated by detection of the healthy conditions of the trees.

Description

Technical field [0001] The patent of the present invention relates to a detection instrument for landscape gardening engineering, especially capable of identifying the growth of trees in a non-destructive state. Background technique [0002] Urban greening trees and ancient trees provide a good ecological environment for residents' work and life, but trees with health problems are one of the important safety hazards of urban life. At present, in terms of eliminating hidden dangers of urban greening trees, some domestic researchers mainly use sound velocity, amplitude and frequency methods to detect internal defects and their positions in wood, but none of the detection instruments they use are dedicated to ultrasonic detection of trees. The corresponding relationship between the ultrasonic A-type wave and the defect displayed at the time is not obvious. Only a professionally trained person can judge whether there is a defect in the wood through the A-type wave, and the pract...
