The invention discloses an internal defect detector of a tree. The internal defect detector comprises a frequency simulator, a code-energy synthesizer, a frequency energy concentrated rebounding plate, an oscillation energy emission module, a frequency coupling and receiving module, a frequency energy converter, a characteristic separation circuit and a signal output module, wherein the frequencysimulator is connected with the code-energy synthesizer, the code-energy synthesizer is connected to two metal plates of the frequency energy concentrated rebounding plate, the oscillation energy emission module is closely arranged in the frequency energy concentrated rebounding plate, the oscillation energy emission module is arranged at one end of a diameter of the tree, the frequency coupling and receiving module is arranged at the other end of the diameter of the tree, the frequency coupling and receiving module is connected with the frequency energy converter and the characteristic separation circuit, and the frequency energy converter and the characteristic separation circuit are simultaneously connected with the signal output module. The internal defect detector is rapid in detection process, simple in detection mode and relatively high in detection accuracy.
Description
technical field [0001] The invention relates to a forestry detection device, in particular to a tree internal defect detector. Background technique [0002] Defects such as hollows, borers and rot inside trees cannot be found and seen from the outside, but these problems are key factors affecting tree growth and wood quality. The current detection methods for internal defects of trees include ultrasonic wave and stress wave, which are all based on the structure without damaging the trunk. However, the detection process of these detection methods for internal defects of trees is relatively complicated, and the feature detection of defects requires complex technical processes. , so it is difficult, time-consuming and costly. Contents of the invention [0003] The object of the present invention is to provide a tree internal defect detector, which can effectively detect the characteristics of the internal defects of trees through the diffusion detection of high-frequency ene...
