Abstract

The invention provides an automatic measuring device and system for a diameter of a standing tree at a breast height. The device comprises a ruler body and a measuring claw module that is movably arranged above the ruler body. The ruler body comprises a fixed grid module including a capacitive grid sensor. The measuring claw module comprises a control module and a moving grid module of the capacitive grid sensor. The moving grid module is electrically connected to the fixed grid module. The fixed grid module and the moving grid module are used for measuring the displacement of the measuring claw module relative to the ruler body and converting the displacement into digital pulse. The displacement of the measuring claw module relative to the ruler body is the diameter of the standing tree at the breast height. The control module is used for obtaining the diameter of the standing tree at the breast height according to the digital pulse. The automatic measuring device and system providedby the invention have the advantages of low cost, convenient operation and easy carrying, according to a wireless transmission function, cumbersomeness of the traditional manual recording is eliminated, and the intelligence of the measurement of the diameter of the standing tree at breast height is achieved.

Description

technical field [0001] The invention relates to the technical field of forestry measurement automation, in particular to an automatic measurement device and system for the diameter at breast height of a standing tree. Background technique [0002] In forest farms and nursery bases, when timber sellers quote timber prices, the diameter at breast height is a very important indicator. However, in our country, the traditional manual contact method is still generally used for the measurement of standing tree diameter, which generally requires the cooperation of two people. One of them uses professional measuring tools, such as diameter tapes, calipers, and diameters at breast height of standing trees, etc.; the other is responsible for recording data. The above method not only has errors, but also is inefficient and consumes a lot of manpower and material resources. Contents of the invention [0003] The invention provides an automatic measuring device and system for the diam...
