Embodiment 1

[0039] The forest area is a fast-growing forest, and the estimated maximum tree diameter is 50cm. The threshold of the laser 7 is set to 60cm, and the reading is 38.7cm.

Embodiment 2

[0041] The forest area is a fast-growing forest, and the estimated maximum tree diameter is 45cm. The threshold of the laser 7 is set to 55cm, and the reading is 42.4cm.

Embodiment 3

[0043] The method for measuring tree diameter comprises the following steps:

[0044] (1) Turn on the power key in the button area 9, set the measurement threshold value of laser device 7 according to the predicted maximum tree diameter, and generally set the threshold value to be larger than the maximum tree diameter by 10cm;

[0045] (2) Aim the muzzle of the laser gun at the center of the tree to be measured, and the distance between the muzzle and the tree shall not exceed 10cm;

[0046] (3) The staff holds the laser gun and slowly moves back until the first indicator light 6 lights up and the sounder 12 emits a prompt sound;

[0047] (4) Stand still and slowly adjust the angle of the laser until the second indicator light 7 turns on and the sounder 12 emits a prompt tone;

[0048] (5) When the first indicator light 6 and the second indicator light 7 are on at the same time and last for more than 1s, the third indicator light 8 is brightened, and the processor 9 will calc...

Abstract

The invention relates to the field of distance measuring devices, in particular to an intelligent tree diameter measuring laser gun and a tree diameter measuring method. A laser distance measurement principle is used, distances from laser points to a tree are measured by three lasers on the laser gun respectively, a tree diameter can be calculated by utilizing a function formula due to fixed angles among the three lasers, a measured result is uploaded to a mobile terminal automatically through a wireless network, after a worker determines the measured result on the mobile terminal, the determined result is uploaded to a Cloud for back-up, and mobile terminal data and Cloud data are automatically and synchronously updated. The intelligent tree diameter measuring laser gun and the tree diameter measuring method disclosed by the invention have the beneficial effects that the device is reasonable in structure, convenient to use, high in reliability and high in measurement accuracy; the operation is simple, easy and convenient, one worker is enough to perform the operation of tree diameter measurement, and automatic measurement, real-time display by a liquid crystal screen and automatic record can be performed by just pressing a measurement press key; the equipment is low in cost and can be widely popularized; the device can also be applied to measurement work in other fields; and during tree diameter measurement, the data is stored in the Cloud at the same time, so that the data is backed up and is also convenient for a person at a far end to look over.

Description

technical field [0001] The invention relates to the field of distance measuring devices, in particular to an intelligent tree diameter measuring laser gun and a method for measuring tree diameters. Background technique [0002] Tree diameter is an important factor in tree growth, and plays a pivotal role in tree investigation and tree growth law research. In actual measurement work, due to the complexity and variability of the forest environment, it has always been a difficult problem to measure tree diameter. The measurement method And measuring tools are relatively backward, so it is necessary to develop a measuring device that is easy to use, fast and accurate. [0003] A high-precision electronic tree diameter measuring instrument and its method (CN201310481170.1) in the Chinese patent database are measuring instruments and methods for tree diameters. According to the parallel principle, a fixed laser guiding device and a sliding laser guiding device are vertically inst...
