Tree diameter at breast height automatic measurer

Abstract

The invention discloses a tree diameter at breast height automatic measurer, which relates to a measurement device, particularly relates to a wireless sensor network-based tree diameter at breast height automatic measurer and belongs to the technical field of tree measurement tools. The tree diameter at breast height automatic measurer comprises a binding band; the binding band is a resistance band; one end of the resistance band is provided with a fixed knot and the other end of the resistance band is provided with a mobile knot; the fixed knot is arranged in a fixed knot box, and a first buckle is arranged on the side surface of the fixed knot box; the mobile knot is arranged in a spring pressure box, a second buckle is arranged on the side surface of the spring pressure box, the first buckle and the second buckle are located in the same horizontal plane, and the first buckle and the second buckle are connected via a clamping band; a fixed knot wire and a mobile knot wire are respectively connected onto the fixed knot and the mobile knot, and tail ends of the fixed knot and the mobile knot are sealed in the spring pressure box; tail ends of the fixed knot wire and the mobile knot wire are bent; and the spring pressure box is internally provided with a measurement control unit. The measurement reading is accurate, the efficiency is high, and the safety is good.

Description

technical field [0001] The invention relates to an automatic measuring instrument for tree diameter at breast height, relating to a measuring device, in particular to an automatic measuring instrument for tree diameter at breast height based on a wireless sensor network, which belongs to the technical field of tree measuring tools. Background technique [0002] The measurement of the growth of tree diameter at breast height is mainly based on the year as the time unit to understand the growth of tree diameter at breast height. Existing girths for tree diameter measurement are comparable in structure to commonly used tapes. In the actual measurement process, the girth is manually placed around the trunk of the guessed tree, and then the measurement result is obtained by reading the readings on the girdle. Since the measurement of tree DBH is generally performed in the field, the staff will be tired after measuring multiple tree DBHs continuously, and the readings will be inac...

AI Technical Summary

Problems solved by technology

Since the measurement of tree DBH is generally performed in the field, the staff will be tired after measuring multiple tree DBHs continuously, and the readings will be inaccurate, especially in winter or summer; in addition, for some remote forests, due to long-term For unattended measurement, you need to find a standard wood every time you measure. At this time, you need to enter an unfamiliar field environment and carry manual tools to measure and record. The measurement efficiency is low and the safety is poor.
