Abstract
The invention is suitable for leveling survey in topography, and relates to an automatic smoothening leveling ruler. The leveling ruler is composed of parts such as a ruler body (1), a circular level (2), a camera (3), a maincenter control center (4), a transmission system (5), a rotation shaft (6) and a ruler pad (7). According to the invention, the circular level (2) can exactly measure a perpendicular condition of the leveling ruler, the camera (3) positioned above the circular level (2) can continually shoot the positions of air bubbles and send the shot photos to the maincenter control center (4) through a transfer system for judgment so as to send out corresponding instructions; and the rotation shaft (6) is adjusted according to the instruction, the position change of the air bubbles of the circular level (2) is introduced until the photos sent back by the camera (3) show that the air bubbles are in the center, and then the leveling ruler is perpendicular. The leveling ruler strengthens the perpendicular precision of the leveling ruler, the perpendicularity of a standing ruler is guaranteed, a measuring error is reduced, and meanwhile, the operation is simpler.
Description
Technical field
The present invention relates to a kind of instrument of surveying and mapping in a kind of mapping science field, specifically relates to the levelling pole that can automatically flatten in a kind of measurement of the level.
Background technology
In mapping science, elevation is one of key element of determining ground point location, all has a very important role in the stages such as the design of engineering construction, construction and managements.The measurement of higher degree is different according to its method and institute use instrument, is divided into measurement of the level and trigonometric levelling.Measurement of the level is the most frequently used a kind of measurement of higher degree method, and for example geometric leveling still is the only resource of Precision Elevation control survey.The principle of measurement of the level is: 2 levelling pole aims at and reading to standing vertically on the ground to utilize the horizontal line of sight that spirit-leveling instrument provides, and has measured 2 discrepancy in elevation, thereby has obtained the elevation of tested point.For the spirit-leveling instrument in the measurement of the level system, very abundant to the research of the aspects such as its error source, method of calibration, instrument improvement both at home and abroad, and as the levelling pole of another parts, domestic research is few.
The employed instrument of measurement of the level is spirit-leveling instrument, and levelling pole is supporting with it scale.Levelling pole is that the materials such as timber, aluminium alloy or fiberglass with dry and high quality are made, and length has 2m, 3m, 5m etc.Whether levelling pole is vertically important to measuring accuracy.About the research of levelling pole, easy to carry how from its accuracy, carry out the aspect such as simple to operate, for example rotates foot pin, and adding one in the lower end of levelling pole rotates foot pin flexibly; Vertical for guaranteeing, add a dismountable level tube etc. at levelling pole.
Levelling pole commonly used is multiplex manually to be flattened, and artificial leveling causes and keeps away unavoidable error, affects the precision of Measurement results; In addition, whether for vertical, vertical chi person determines that according to the sight line of oneself position of standing is different, and just there is deviation in the result who sees, and is not necessarily correct.If a kind of can automatically the leveling arranged, and whether vertical with the instrumental science check, error reduces, and precision can improve a lot.
Summary of the invention
The objective of the invention is to have overcome deficiency of the prior art, a kind of levelling pole that can automatically flatten is provided, guarantee that levelling pole is in plumbness, reduces measuring error.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
The levelling pole of this automatic leveling partly is comprised of blade 1, circular bubble 2, camera 3, maincenter control center 4, transmission system 5, turning axle 6, foot pin 7 etc.In measuring process, the vertical situation of levelling pole is accurately measured by circular bubble 2, places the position of 3 pairs of bubbles of camera of circular bubble 2 tops constantly to take, and the photo of taking is sent to maincenter control center 4 by transmission system 5.Opertaing device is judged according to the method that sets in advance, and sent the order that needs adjustment: namely ought receive bubble photo placed in the middle, it is vertical to judge blade, sends the order of " turning axle is motionless, keeps standing state "; When receiving bubble photo not placed in the middle,, send the instruction of " how many degree of axial rotary direction skew " then according to the angle of deflection.Regulate according to the instruction of receiving with the turning axle 6 of foot pin 7 combinations, introduce the change in location of circular bubble bubble, until the photo that camera is passed back shows that bubble is placed in the middle, then send the motionless instruction of turning axle, levelling pole is vertical this moment.
Compared with prior art, the invention has the beneficial effects as follows:
By this improved sensing and control system, strengthened the vertical degree of accuracy of levelling pole, guarantee that vertical chi is vertical, reduce measuring error, simultaneously also so that operation is simpler.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
The present invention includes the compositions such as blade 1, circular bubble 2, camera 3, maincenter control center 4, transmission system 5, turning axle 6, foot pin 7.
When measuring,
1, the vertical situation of blade 1 can show at circular bubble 2, and the bubble on the circular bubble is placed in the middle, illustrates that then blade is vertical, otherwise deflection; Place the camera 3 on the circular bubble constantly circular bubble to be taken pictures, and the photo that photographed is passed to maincenter control center 4 by transmission system 5;
2, central control system 4 is after receiving photographic intelligence, and comparison film information is judged and classify whether be divided between two parties two classes according to bubble.When judging that bubble is placed in the middle, it is vertical then to judge blade, sends the instruction of " blade is vertical, and the maintenance present situation is motionless " for turning axle 6 by transmission system 5; Not placed in the middle when bubble, it is not vertical then to judge blade, and calculates direction and the angle of deflection, draws the scheme that needs reaction, sends the instruction of " the blade out of plumb is to how many degree of certain direction rotation " for turning axle 6 by transmission system 5;
3 and the turning axle 6 of foot pin 2 combinations receiving instruction, carry out at once instruction, keep motionless or be rotated, in the time of rotation, can cause the rotation of blade 1, thereby the bubble of circular bubble 2 can change by occurrence positions, and camera 3 can in time be sent to maincenter control center 4 to the information that changes, in case bubble is placed in the middle, then send the instruction of " blade is vertical; the maintenance present situation is motionless ", turning axle 6 stops to carry out instruction, and this moment, levelling pole reached vertical.
The undeclared part that relates among the present invention is same as the prior art or adopt prior art to be realized.
