Nondestructive agilawood formation ultrasonic detection system based on single chip microcomputer control

Abstract

The invention provides a nondestructive agilawood formation ultrasonic detection system based on single chip microcomputer control. The system comprises a single chip microcomputer and an ultrasonic transmitting circuit, an ultrasonic receiving circuit, a display circuit, a power circuit, a reset circuit and an LED control circuit which are connected with the single chip microcomputer. The ultrasonic transmitting circuit amplifies and detects a signal and then transmits the signal; after being transmitted, the ultrasonic waves return according to the original path, are amplified and filtered and then are received by the single chip microcomputer; a counter stops working and obtains time; the single chip microcomputer is further connected with a temperature detection module; the temperaturedetection module sends measured temperature information to the single chip microcomputer. The speed is corrected to obtain the agilawood formation area of the measured position. The nondestructive agilawood formation ultrasonic detection system based on single chip microcomputer control has the advantages of being convenient to use, high in detection efficiency, capable of effectively protectingprecious plants and the like, and can effectively protect precious trees.

Description

technical field [0001] The invention relates to the technical field of detection of agarwood knots, in particular to a non-damaging ultrasonic detection system of agarwood knots controlled by a single-chip microcomputer. Background technique [0002] Agarwood is a resinous wood of the plant Agarwood of the Thymelaceae family. Distributed in Guangdong, Hainan, Guangxi, Fujian and other places, it has the effects of promoting qi and relieving pain, warming the middle and relieving nausea, absorbing qi and relieving asthma. When the trunk is bitten by insects, natural disasters or man-made damage, it will automatically secrete oil in the trunk. This is also the self-healing property of trees in nature. After the oil secreted is infected by a specific fungus in nature, as time goes by, this oil will emit a strange fragrance. The black oil is the agarwood. Because of its unique fragrance, it is often used in the preparation of spices and perfumes. At present, people detect agar...

Problems solved by technology

This method is not only destructive to the precious agarwood, and non-destructive testing cannot be achieved, but also the process of taking agarwood from the tree tray is time-consuming and laborious, and has high requirements for operators, even a very skilled operator , it is still inevitable to leave woody residues on the surface of agarwood. Therefore, how to efficiently and accurately measure the aroma of agarwood is a huge problem encountered by researchers at present.
