Description
Technical field
The present invention relates to a kind of device of in forest resource monitoring and forestry investigation, measuring the height of tree, measure the device of the height of tree under particularly a kind of mark post condition of before flat distance of accident water gaging and tree, not placing conjunction measuring.
Background technology
In forest resource monitoring and forestry investigation, the height of tree is a very important factor, and the measurement of the height of tree is an insoluble problem always, and it is high to adopt eye estimating method or height finder to survey usually in the real work.
Eye estimating method is closely related with individual's experience, and measuring accuracy has no to ensure.
What height finder was at present the most frequently used is Bu Lulaisi (Blume-Leiss) height finder.When measuring the height of tree, required before the height of every survey one strain trees, must be at first measure the horizontal range (15,20,30 or 40m) of a standard length with aid with the Bu Lulaisi height finder.Be subjected to the restriction of factors such as landform, the gradient, sylvan life vegetation, the density of crop in the forest, the measurement of standard level distance is very inconvenient or very difficult, even measured the standard level distance, because blocking of crown canopy, often can't see treetop again, therefore, the Bu Lulaisi height finder is inapplicable or inefficient in forest with a varied topography, that density is big slightly or will measure the height of a lot of trees the time.Also has Chris village (Christen) height finder, the Chris collects height finder need place the mark post of conjunction measuring as aid before tree, and read text scale becomes close gradually with the increase of the height of tree, measuring error is bigger, when the height of tree reaches 15m when above, the Chris collects height finder and has been difficult to reading, so, superseded substantially in surveying high workload at present.Publication number is that the height finder of describing in the application for a patent for invention of CN101749988A need be placed the mark post of conjunction measuring as aid equally before tree.In view of the foregoing, invent a kind of simple and practical, requirement is not surveyed horizontal range, not be used in the mark post of placing conjunction measuring before the tree, the height finder that can select measuring point has arbitrarily just become this field forest workers to pursue for many years always target, in order to reach this target, people have invented various height finders in succession, but, eventually because practicality is not high, and fail to substitute the status of Bu Lulaisi height finder.
Summary of the invention
The technical problem to be solved in the present invention is to need when measuring the height of tree in the existing height finder earlier measuring point to the horizontal range of tree measured out or need place conjunction measuring before tree shortcomings such as mark post, proposes that a kind of not requirement is surveyed horizontal range, not be used in the mark post of setting preceding placement conjunction measuring, is applicable to forest environment, simple and practical new and effective height measuring device.Use this device, can choose measuring point wantonly, reach the purpose of measuring the trees height quickly and efficiently.
The present invention is achieved in that overall by being placed on the bracing frame, forming perpendicular to the gage and the coupled and tilted-putted sighting bar of surface level; Sighting bar and gage can vertically rotate with horizontal direction on bracing frame, can fix when turning to the appropriate location, and the bracing frame height can be regulated; There is a shared accurate pin position that the sighting bar front end is connected with gage, and respectively there is pin surely at middle part and rear portion, and the tip of three accurate pins will be all the time point-blank; Length on the sighting bar between accurate pin can elongate or shorten, and will guarantee all the time when elongating or shortening that the accurate pin in middle part is constant to the length ratio of the accurate pin in two ends; Gage top is connected with sighting bar by shared accurate pin, and sighting bar and gage can freely rotate around shared accurate pin, gage middle part and end respectively have pin surely, wherein pin maintains static surely, another accurate pin can move up and down along gage, the tip of two accurate pins and shared accurate pin will be all the time in a straight line, and this straight line will be perpendicular to surface level, and promptly three accurate needle tips will be on the perpendicular bisector of gage; The gage lower end can hang a weight with the straight line that guarantees three accurate pins of gage place fully perpendicular to surface level.
Described accurate needle tip is to be understood that any position that is used to aim on the pin that is as the criterion.Such as, the circular cone top of conical accurate pin, a limit of the accurate pin of trihedral, the side of the accurate pin of right cylinder.If accurate needle tip is a limit, then described accurate needle tip will point-blank be interpreted as will be in one plane.Length between described accurate pin also is meant the length between the accurate needle tip.
As shown in Figure 1, the basic operation method is as follows when measuring the height of tree, and removable with the terminal accurate pin of gage is example:
1, sighting bar and gage are placed on the bracing frame, make gage, sighting bar OAB is aimed at treetop E, make accurate pin on the sighting bar and treetop in line, fixedly sighting bar perpendicular to surface level;
2, the accurate pin A in middle part on the mobile again sighting bar makes that the middle part on this accurate pin and the gage BCD is fixed accurate pin C and set basic F three in line, fixedly the accurate pin on the sighting bar;
3, the movable accurate pin D of mobile again gage end makes accurate pin O in this accurate pin and sighting bar rear portion and the basic F three of the tree that previous step aimed in line, fixing movable accurate pin D;
4, read the scale of movable accurate pin D correspondence, be the height of tree.
Note, when twice aiming tree base, aim at the same position of tree base fully, this and measuring accuracy are closely related.For the ease of when twice aiming tree is basic, aiming at the same position of tree base fully, imaging device such as camera, telescope can be installed at accurate pin C place, the middle part of accurate pin A place, the middle part of sighting bar OAB or gage, imaging device is installed at terminal accurate pin D place at accurate pin O place, the rear portion of sighting bar OAB or gage, the axis of two imaging devices will keep respectively overlapping with sight line ODF and sight line ACF, the picture that two imaging devices are taken the photograph shows at grade by cable, can improve pointing accuracy like this.
When tree base is kept off and when invisible, as long as along moving certain altitude on the trunk as the tree base, the height that records adds that this that move highly is the height of tree.
If the accurate pin C in gage middle part is removable, want during measurement earlier the accurate pin O in sighting bar rear portion with the gage accurate pin D of end and set basic F in line, movable accurate pin C on the mobile then gage, make on the sighting bar accurate pin A in middle part and the accurate pin C in middle part on the gage and set basic F in line.
What sighting bar was aimed at during above-mentioned measurement is treetop.In like manner, also sighting bar can be aimed at the tree base, as shown in Figure 2.The accurate pin O in sighting bar rear portion during measurement, the terminal accurate pin D of gage and treetop E in line, the accurate pin A in sighting bar middle part, gage middle part accurate pin C, treetop E in line, the x distance of pin B that promptly be as the criterion to the basic F of tree.
Above-mentioned measuring process is exactly middle centering, edge-to-edge, fixing back activity earlier in brief, and promptly the accurate pin of relevant position aligns on sighting bar and the gage, and elder generation is to fixing accurate pin end, and the back is to the accurate pin end of activity.
The mode that sighting bar and gage are placed on the bracing frame has two kinds, and a kind of is to be suspended on the bracing frame by sighting bar, and another kind is to be erected on the bracing frame by gage.The advantage of preceding a kind of mode is the level correction that does not need to carry out bracing frame, and shortcoming is that gage can rock with the wind when measuring in the weather of wind is arranged, and has any problem during aiming; The advantage of a kind of mode in back is that the influence of wind is less, and the ability that promptly adapts to weather is stronger, and shortcoming is to carry out the level correction of bracing frame.When employing is erected at mode on the bracing frame by gage, the bar of a variable-length need be installed between sighting bar and gage, in order to fixing sighting bar at any time when measuring.
Described each accurate pin can be any tangible object that can play the aiming effect, also can be invisible.
Such as, the off-centre operation that a radii fixus is installed, can freely rotate on shared accurate pin B, center of gravity that promptly should circle is or not the center of circle, but on the limit a bit, when measuring like this, the line in this round center of gravity and the center of circle must be on the perpendicular bisector of gage.One straight-bar is installed at the accurate pin A in the middle part of sighting bar OAB place, in the junction of straight-bar and sighting bar one whirligig is arranged, make this straight-bar and sighting bar angle along with the angle of sighting bar and gage, accurate pin B to the length of accurate pin C and accurate pin B to accurate pin A length variations and change, thereby make this straight-bar can aim at the accurate pin C in middle part on the gage all the time, then accurate pin C can not need, be that accurate pin C is invisible, and accurate pin A has also become a straight-bar.Just can know by simple mathematical trigonometric function knowledge, the angle of straight-bar and sighting bar can be calculated to three factors of length of accurate pin A to the length of accurate pin C, accurate pin B by the angle of sighting bar and gage, accurate pin B, and this calculating formula is also very simple.
Aforementioned straight-bar also can change various imaging devices such as camera into, telescope etc., the driving of its upper rotary device can be driven by single-chip microcomputer and the drive unit of being controlled thereof, and measurement of length can be measured by electronic length measuring system such as volume grate electronic length measuring system, the measurement of angle also can be by the round linear measure longimetry that is converted on the annulus, then single-chip microcomputer receives the length on the aforementioned annulus, accurate pin B is to the length of accurate pin C, accurate pin B calculates the angle that straight-bar need rotate to three factors of length of accurate pin A, rotates to the tram of pointing to accurate pin C thereby drive straight-bar.When accurate pin C was fixing accurate pin, accurate pin B was a definite value to the length of accurate pin C, in fact single-chip microcomputer only two variablees of need just can calculate the anglec of rotation of the straight-bar at accurate pin A place.The control of the anglec of rotation also can realize by the Single-chip Controlling stepper motor.
In like manner, after the straight-bar of aiming effect was together installed at the accurate pin O in the rear portion of sighting bar OAB place, movable accurate pin D also can be invisible.According to the length relation between the accurate pin on the aforementioned sighting bar as can be known, only need to increase by a variable be accurate pin D to its anglec of rotation to the length of accurate pin B, add that described two variablees of leading portion can calculate.When the accurate pin D of activity was invisible, the displacement of movable accurate pin D can be represented with the displacement of reading pointer on the sighting bar.
Because gage is the carrier of accurate pin, if middle part on the gage and terminal accurate pin are invisible, then gage can shorten greatly, even shortens to and be hidden in sighting bar the inside, like this from seeming that in appearance gage is exactly invisible.Such as the off-centre operation that shortens on the shared accurate pin noted earlier, because this moment, the gage role only was the angle that produces between gage and the sighting bar.And the scale that is used to show height value on the gage can be transferred on the sighting bar and shows.
In like manner, if the accurate pin of accurate pin in the middle part on the sighting bar and rear portion is invisible, then sighting bar also can be invisible in appearance, and at this moment, accurate pin in the middle part on the gage and terminal accurate pin are a straight-bar or other imaging device and can forward suitable angle to along with the variation of similar aforementioned three factors.In this case, an imaging device should be installed by the place at shared accurate pin, be used to aim at treetop or tree base, and imaging is transferred to position suitable on the gage observes to make things convenient for eyes, the angle of sighting bar and the gage axis of imaging device and the angle of gage thus obtains.
The following describes the principle of work of this device.
As shown in Figure 1, if the length of the sighting bar accurate pin A in middle part accurate pin O to the rear portion and accurate pin A equal n to the length ratio of shared accurate pin B, shared accurate pin B is x to the distance of treetop E, treetop E is h to the height of the basic F of tree, shared accurate pin B is c to the length of the accurate pin C in gage middle part, shared accurate pin B is d to the length of the terminal accurate pin D of gage, and the accurate pin A in sighting bar middle part is a to the length of shared accurate pin B, and then the length of the sighting bar accurate pin A in middle part accurate pin O to the rear portion is na.
Because of gage and trunk all perpendicular to surface level, so gage is parallel with trunk, so straight line OBE, ODF form two similar triangles, straight line ABE, ACF also form two similar triangles, i.e. Δ OBD ∽ Δ OEF, Δ ABC ∽ Δ AEF sets up.
Can get by the similar triangles theorem: BD: EF=OB: OE, BC: EF=AB: AE, i.e. d:h=(na+a): (na+a+x), c:h=a:(a+x);
Separate this equation with two unknowns group, can get h=ncd/[(n+1) c-d).
As n=1, h=cd/ (2c-d) then; As n=1, c=64 centimetre, then h=64d/ (128-d) centimetre.
In the above-mentioned measuring process, n is a fixed value, and in order directly to indicate height of tree value on gage or sighting bar, a value can setting among c and the d is fixing, and height of tree h only changes with a factor like this.
Set the value of n and shared accurate pin B to the length between the fixing accurate pin of gage, the movable accurate pin that calculates different height of tree correspondences according to above-mentioned formula arrives the length of shared accurate pin B again, on the gage that this length is directly indicated, can directly read the height of tree value during measurement.Also can on sighting bar, establish a reading pointer and indicate the rule of height of tree value, the displacement of the accurate pin of activity is transformed on this reading pointer by pulley and line.
When the accurate pin in gage middle part fixedly the time, with shared accurate pin be zero graduation, shared accurate pin fix length between the accurate pin to the gage middle part be that 64 centimetres, n=1 are example, following table has been listed the scale value of the movable accurate pin of end on the gage of different height of tree value correspondences.
