Abstract
The utility model relates to a device based on laser real -time supervision meadow grass layer height. Its constitutional features is that the laser instrument has been put to the flexible arm tip of level, and vertical measuring stick is that scaled, a lesson pipe box connects a pipe joint telescopic device, and the sleeve pipe department of meeting uses the fix with screw, and the sleeve pipe is built -in to have vertical bubble, and static controller on the vertical measuring stick sets up liquid crystal display, controller interface, SD card slot, measures the button, sets up button and adjustment button on the controller. The laser instrument passes through the wire and links to each other with controller interface. The utility model discloses simple structure, easy operation can be at the real -time precision measurement in scene grass layer height, and swift convenient, measurement accuracy reaches the millimeter level. Compare with having measuring tool now, effectively avoid visible reading, record error.
Description
Technical field
This utility model belongs to a kind of survey tool, specifically refers to a kind of device monitoring meadow turf height based on laser in real time, can be applicable to natural meadow observation experiment.Improve efficiency and the precision of meadow field investigation.
Background technology
The instrument that the ground survey of meadow turf height uses at present has: 1) use ruler (tape measure) directly to measure.Ruler is placed perpendicular to the ground, visually reads grass layer top scale on ruler, estimated the turf height in region to be measured by the average taking repetitive measurement.The advantage of the method is simple and convenient, easily operates.Shortcoming is that certainty of measurement is affected by human factors relatively greatly, and efficiency is low；2) use rule formula to survey grass dish to measure.Landform, environment, meadow cover degree etc. are all had higher requirements.The most common survey grass dish mostly is rule formula and surveys grass dish.Its ultimate principle is, when the survey grass dish with certain area and quality from top to bottom lands, makes due to the support by plant survey grass dish rest on the height that distance ground is certain, surveys the grass dish height away from ground by measuring, obtain grass layer compression height.The advantage of the method is that certainty of measurement is high, and measurement result has certain regional representativeness.Its shortcoming is: (1) the method measurement to turf height be a kind of compression height, its compression degree depends on area and the weight surveying grass dish；(2) when meadow is the most sparse, meadow is not enough to the support degree surveying grass dish, surveys grass dish and will fall on the ground, it is impossible to records turf height；(3) certainty of measurement is affected and restriction by measuring environment.As when meadow relief relatively big, grassland vegetation growing way heterogeneity, or when there are stone, hard branch in earth's surface, error is bigger；(4) measurement result needs visually to read, and there is certain personal error.In a word, ruler method and survey grass dish measurement are required for visually reading turf height, and the impact of anthropic factor is relatively big, and general accuracy of reading is difficult to reach 0.1cm.
Summary of the invention
In view of the deficiencies in the prior art, the purpose of this utility model is to propose a kind of device monitoring meadow turf height based on laser in real time, improves meadow turf height monitoring accuracy and efficiency with this, provides technical support for grassland resources field investigation work.
The purpose of this utility model is achieved in that
A kind of device monitoring meadow turf height based on laser in real time, by laser instrument, horizontal extension arm, vertically measures bar, controller and disc-shaped base and forms.Horizontal extension arm and vertically measurement bar connect, vertically measure bar to be connected with disc-shaped base, horizontal extension arm end is equipped with laser instrument, vertically measuring bar is that one graduated, a pipe joint is socketed a telescopic device of pipe joint, sleeve pipe joint is screwed, sleeve pipe is built-in with vertical bubble, vertically measures static controller on bar, controller arranges LCDs, control unit interface, SD card slot, measurement button, settings button and regulation button.Laser instrument is connected with control unit interface by wire.
Compared with prior art, its advantage is this utility model:
1) this utility model simple in construction, easily operates, can real-time precision measurment turf height at the scene, efficient and convenient certainty of measurement reaches grade.Compare compared with survey tool, be prevented effectively from visible reading, recording error；
2) core of this device is laser instrument, and volume is little, precision is high, cruising time is long, can meet long-time field Continuous Observation demand；
3) measure on bar and be labeled with scale, facilitate operator's real-time core to measurement result, calibrate laser range finder height；
4) vertically measurement bar can stretch, and can measure the height of bar according to turf height regulation, with satisfied different turf height observation needs, dismounts parts and is easy to carry.
5) bottom measuring bar uses disc-shaped design, it is to avoid measures bar and inserts in soil, affects certainty of measurement；
6) horizontal extension arm is scalable, meets the Continuous Observation demand in flat site.

Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is vertically to measure bar schematic diagram in Fig. 1.
Fig. 3 is vertically to measure controller schematic diagram on bar in Fig. 1.
Detailed description of the invention
With embodiment, the technical solution of the utility model is further described again below in conjunction with the accompanying drawings:
A kind of device monitoring meadow turf height based on laser in real time, is made up of laser instrument 1, horizontal extension arm 2, vertically measurement bar 3, controller 4 and disc-shaped base 5.Horizontal extension arm 2 and vertically measurement bar 3 connect, and vertically measure bar 3 and are connected with disc-shaped base 5, and are perpendicular to ground.Horizontal extension arm 2 end is equipped with laser instrument 1, vertically measuring bar 3 height is 0-150cm, telescopic device is formed by three joint sleeve combination, sleeve pipe joint screw 7 is fixed, middle sleeve pipe is built-in with vertical bubble 6, vertically measure static controller 4 on bar 3, controller panel arranges LCDs 8, control unit interface 9, SD card slot 10, measures button 11, settings button 12 and regulation button 13.Laser instrument 1 is connected with control unit interface 9 by wire.
When measuring turf height, first this device is placed on meadow, laser instrument 1 is fixed on the position of distance ground certain altitude, and horizontal vertical is downward, vertically measure the sleeve pipe in the middle of bar 3 and be built-in with vertical bubble 6, being easy to judge vertically to measure bar 3 whether positioned vertical, push-and-pull is vertically measured bar 3, can be regulated according to turf height situation and vertically measure the flexible height of bar 3；It is then turned on device, the height (H) of current expansion link is set by the settings button 12 on controller panel and regulation button 13；Start laser instrument 1 by the measurement button 11 on controller panel and carry out range operation.Laser instrument 1 have aiming, find range, the function such as record.Launching downwards laser beam, laser obtains the distance (h) of grass layer distance from top laser instrument through the reflection return laser light device of grass layer top vane, the time difference coming and going grass layer top by calculating laser；Therefore the laser instrument distance (H) away from ground it is known that calculate turf height (H-h).Controller 4 is by record measurement time and turf height information, and shows measurement result on liquid crystal display 8 in real time or check historical measurement data.
