Measuring device for detecting internal defects of wood and processing method thereof

Abstract

The invention discloses a measuring device for detecting internal defects of wood and a processing method thereof. The measuring device comprises 16 electrode sensors and a data acquisition and processing platform. The 16 electrode sensors are arranged around to-be-detected wood at equal intervals. The data acquisition and processing platform includes a PXI controller, a data acquisition board card, a multiplexer matrix switch board card and an excitation power supply. The 16 electrode sensors are respectively connected with terminals r0 to r15 of the multiplexer matrix switch board card; themultiplexer matrix switch board card is respectively connected with the data acquisition board card and the excitation power supply; and the multiplexer matrix switch board card, the data acquisitionboard card and the excitation power supply are respectively connected to the PXI controller through a PXI bus. According to the measuring device and the processing method thereof, the measuring devicehas a simple structure and the processing method is performed conveniently and rapidly; the measuring result is accurate; the utilization rate of the wood is effectively increased; the forest resources are saved; and the application prospect is broad.

Description

technical field [0001] The invention belongs to the technical field of defect measurement, and in particular relates to a measuring device for detecting internal defects of wood and a processing method thereof. Background technique [0002] With the rapid development of my country's economy, it has brought about a sharp increase in the demand for various resources. my country's consumption of wood and wood products is huge. The rational use of forest resources is the key to sustainable development. The structure of my country's forest resources is quite special. The total amount of forest resources occupies the forefront of the world. However, as a country with a large population, the per capita proportion of my country's forest resources is far lower than the world average. As a valuable renewable resource, the forest is characterized by a long regeneration period, and it is difficult to recover in a large amount in a short period of time. Due to the limitation of technica...
