The utility model discloses simple structure, convenient to use are particularly suitable for the measurement of the diameter of the higher tree crown in thicker trees or position, and the user only needs to aim at hand -held type laser diameter measuring instrument for forestry's muzzle the surface of the trees of will measuring, and the axial direction of edge perpendicular to trees is strafed once, can obtain diameter or the cross -sectional area of trees, and labour saving and time saving has alleviateed the work degree of difficulty of survey crew.
Description
Technical field
The utility model belongs to survey instrument technical field, is specifically related to a kind of forestry Handheld laser caliper, is particularly suitable for the measurement of the diameter of the higher tree crown of thicker trees or position.
Background technology
In order to understand the production status of trees, work on forestry personnel often will carry out survey record to the diameter of trees and cross-sectional area, the diameter of current measurement trees and cross-sectional area are all use common tape, after first measuring the girth of trees, diameter and the cross-sectional area of trees is gone out again by formulae discovery, usually need to be calculated by hand computation or counter, waste time and energy.
For this reason, Chinese patent CN201520064738.4 discloses a kind of leather measuring tape with diameter scale mark, directly diameter can be read when using the type leather measuring tape to measure the girth of trees, improve work efficiency, but need around trees pole one week owing to measuring trees, when the diameter of the higher tree crown of the thicker trees of measurement or position, one people has been difficult to the measurement to trees girth, need many people to coordinate and just can complete measurement, increase manpower consumption for this reason, very inconvenient.
Laser diameter measuring instrument directly can measure the diameter of object, and degree of accuracy is higher, but existing laser diameter measuring instrument is all made up of generating laser and laser pickoff two parts, during use, respectively generating laser and laser pickoff are positioned over the both sides of testee, make generating laser, testee and laser pickoff are in a straight line, the region that laser pickoff does not receive laser signal is the region that testee blocks, the distance between two laser signals of the edges of regions that is blocked that laser pickoff receives is the diameter of testee.Because laser pickoff placed by needs, this laser diameter measuring instrument is general only for measuring the diameter of the less object of diameter, the position of mobile generating laser or laser pickoff is needed when measuring the diameter of thicker trees, use inconvenience, even cannot operate when the diameter of the tree crown needing measuring position higher.
Utility model content
For avoiding the weak point existing for above-mentioned prior art, the utility model provides simple, easy and simple to handle, the time saving and energy saving hand-held tree diameters measuring instrument of a kind of structure.
The technical matters that the utility model solves realizes by the following technical solutions:
A kind of forestry Handheld laser caliper, comprise generating laser 1, laser pickoff 2, signal processor 3, display 4 and supply unit 5, generating laser 1, laser pickoff 2, signal processor 3 and display 4 are all connected with supply unit 5, in described generating laser 1, there is spinner, for controlling the rotation of generating laser 1, in described laser pickoff 2, there is timer, the time of launching for recording laser and the time of laser pick-off.
Preferably, the external form of described forestry Handheld laser caliper is gun shaped, and generating laser 1 is adjacent with laser pickoff 2, is positioned at muzzle end, and generating laser 1 is positioned at the outside of laser pickoff 2; Signal processor 3 is adjacent with display 4, is positioned at the junction of muzzle end and pikestaff end, and display 4 is positioned at the outside of signal processor 3, and one end of signal processor 3 is connected with laser pickoff 2, and the other end is connected with display 4; Supply unit 5 is positioned at pikestaff end, is positioned at the bottom surface of signal processor 3 and display 4.
Preferably, described forestry Handheld laser caliper also comprises the USB interface for deriving measurement data, and described USB interface is positioned at the end face of signal processor 3.
Preferably, the anglec of rotation of described spinner is 10 ° ~ 30 °, and assay intervals is 0.01 ° ~ 0.2 °.
Preferably, described supply unit 5 is charge power supply or battery.
Forestry Handheld laser caliper of the present utility model utilizes laser to carry out the instrument of Accurate Determining to the distance of target, its principle of work is: the muzzle of forestry Handheld laser caliper is aimed at the surface of the trees that will measure by user, generating laser 1 launches a branch of very thin laser signal to surface of trees, the angle that spinner recording laser in generating laser 1 is launched also is transferred to laser pickoff 2, laser signal is reflected back in surface of trees, received by laser pickoff 2, the distance between laser pickoff 2 and reflection spot is gone out according to the laser emission time of the timer record in laser pickoff 2 and laser pick-off Time Calculation, and by laser pickoff 2, this range data and corresponding Laser emission angle are transferred to signal processor 3, generating laser 1 rotates by the spinner subsequently in generating laser 1, with the assay intervals of 0.01 ° ~ 0.2 ° for repeating above-mentioned ranging step, until laser pickoff 2 does not receive the laser signal of reflection, signal processor 3 goes out the surface profile of trees according to the data fitting received, and filtering matching is carried out to this surface profile, provide diameter data, and the surface profile of trees and the diameter data simulated are transferred to display 4, display 4 shows.
The beneficial effects of the utility model are: structure is simple, easy to use, the muzzle of forestry Handheld laser caliper only need be aimed at the surface will measuring trees by user, strafe once along the direction perpendicular to trees axis, diameter or the cross-sectional area of trees can be obtained, also can strafe and repeatedly average, time saving and energy saving, alleviate the work difficulty of survey crew, particularly for the measurement of the higher tree crown of thicker trees or position.
