Embodiment Construction

[0016] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the protection scope of the present invention.

[0017] Such as figure 1 , figure 2 The trunk laser detection device shown includes a fixed plate 1 , a laser generator 2 , a photodetector 3 , a light output tube 4 and a light input tube 5 .

[0018] The light output tube 4 and the light input tube 5 are pointed thin tubes with non-light transmission and high hardness, such as stainless steel. The light output tube 4 and the light input tube 5 are arranged at intervals up and down on the front side of the fixed plate 1, and both the light output tube 4 and the light input tube 5 are perpendicular to the front side of the fixed plate. The length of the light ou...

Abstract

The invention provides a trunk laser detector, comprising a fixing plate, a laser generator, a photoelectric detector, a light outlet pipe and a light inlet pipe; the light outlet pipe and the light inlet pipe are vertically arranged on a front side face of the fixing plate at intervals; the length of the light outlet pipe is more than that of the light inlet pipe; a transparent clapboard is arranged in each of the light outlet pipe and the light inlet pipe, and can divide the light outlet pipe and the light inlet pipe into front and back sections; fluid discharge holes are respectively arranged on the front pipe walls of the light outlet pipe and the light inlet pipe, and fluid at the inner part of the trunk enters from front end openings of the light outlet pipe and the light inlet pipe and then flows out from the corresponding fluid discharge hole; the laser generator and the photoelectric detector are installed on the fixing plate, and the laser generator is forwards extended to the back end of the light outlet pipe, and the photoelectric detector is extended to the back end of the light inlet pipe. The device is simple in structure, convenient to operate, and high in accuracy.

Description

technical field [0001] The invention relates to the technical field of tree growth monitoring, in particular to a laser detection device for monitoring the internal conditions of tree trunks. Background technique [0002] As an important part of the tree, the trunk plays the role of transporting nutrients and water. Therefore, monitoring the internal runoff data of the trunk and obtaining the nitrogen, phosphorus, potassium and other nutrients and chlorophyll content in the trunk are extremely important for studying tree growth and analyzing the ecological environment. [0003] Patent CN102564962A discloses a system and method for detecting nutritional components of fruit trees, which uses a visible-near-infrared spectrum acquisition unit to scan the sample of fruit tree leaves to obtain its visible-near-infrared spectrum signal and transmits it to the data analysis and processing unit. The position information and the sampling time of the leaf sample of the fruit tree to b...
