Embodiment Construction

[0024] see figure 1 , figure 2 As shown, a belt-type shock wave imaging system for anomalies inside a tree trunk includes a flexible strip 1 and a ring-type laser coordinate measuring instrument. A plurality of probe holes are arranged in the strip 1, and each probe hole is respectively perpendicular to the strip With and through the strip 1, and a plurality of probe jacks are arranged side by side on the strip 1 along the extension direction of the strip 1, each probe jack is respectively inserted with a probe 2, and the ring laser coordinate measuring instrument includes a ring 3 , there is a scale indicating the arc of the ring on the ring 3, a laser rangefinder 4 is slidably installed on the outer ring surface of the ring 3, and the outgoing light of the laser rangefinder 4 can pass through the ring 3 in the radial direction and point to the ring 3 centers; the strip 1 is wound on the trunk 5 to be measured, the elastic wave probe 2 inserted on the strip 1 is in contact ...

Abstract

The invention discloses a belt-type seismic wave imaging system and method for tree trunk interior abnormity. According to the system and the method, a special probe on a belt is matched with a ring type laser coordinate tester, a seismograph, a seismic wave generator and seismic wave CT imaging software for carrying out CT scanning on abnormal conditions of a tree structure, then a seismic wave velocity distribution characteristic picture for the tree trunk interior is obtained, and then the interior structural characteristics are evaluated, so that effective technical parameters are provided for the health examination of trees.

Description

technical field [0001] The invention relates to the field of tree trunk internal structure measurement systems, in particular to a tree trunk internal anomaly belt seismic wave imaging system and method. Background technique [0002] Trees form tree holes or hollow trunks due to various reasons causing wounds, reducing the firmness of the trunks and shortening the lifespan of trees, especially the health status of valuable ancient trees is particularly important; People and property losses caused by collapse, tree health detection has attracted more and more attention. Using the seismic wave CT scanning detection technology system can realize the rapid detection of the internal structure of the tree and its abnormality. According to the first arrival time of the picked-up elastic wave penetrating the forest, analyze the image of the wave field propagation speed or frequency harmonic feature change, and judge the abnormal position of the internal structure of the tree trunk ...
