Abstract

The invention relates to the field of wood board detection, in particular to a method and system for detecting wood bulges. A wooden bulge detection method is shown, comprising the steps of: receiving a signal sent by a transmitting transducer by a receiving transducer; calculating the number of echo signals in the signal greater than a preset threshold; The number of echo signals used to determine whether there is a bulge on the board; the transmitting transducers are evenly spaced on one side of the wood board production line, and the receiving transducers are evenly spaced on the other side of the wood board production line. By setting a plurality of transmitting transducers and receiving transducers on both sides of the wood board production line, the receiving transducers receive the signals sent by the transmitting transducers, and by judging the number of echo signals greater than the first preset threshold, that is It can be determined whether there are bulges on the board.

Description

technical field [0001] The invention relates to the field of wood board detection, in particular to a method and system for detecting wood bulges. Background technique [0002] In the prior art, more and more furniture is made of particleboard, and the quality of the material of the particleboard has a direct impact on the quality of the furniture, especially whether the particleboard has bulges or not. At present, there is no good detection method for whether there are bulges in the particleboard. Contents of the invention [0003] For this reason, it is necessary to provide a wooden bulge detection method to solve the problem that the wooden bulge cannot be monitored. The specific technical scheme is as follows: [0004] A method for detecting wooden bulges, comprising the steps of: receiving a signal sent by a transmitting transducer by a receiving transducer; calculating the number of echo signals greater than a preset threshold in the signal; The number of wave sig...
