Description
Technical field
The utility model is related to the measurement of field of measuring technique, especially spirit level instrument height.
Background technology
Spirit level is to set up the instrument that horizontal line of sight determines the ground point-to-point transmission discrepancy in elevation.Principle is to be surveyed according to measurement of the level principle
Measure the discrepancy in elevation between ground point.Critical piece has telescope, pipe spirit level（Or compensator）, vertical axis, pedestal, foot screw.By structure
It is divided into tilting level, automatic compensated level, laser level and electronic level.It is divided into precision level and general by precision
Logical spirit level.
At present, electronic level sight scale and focusing still needs to visual progress.After manual debugging, scale bar code is on the one hand
It is imaged on telescope differentiation plate, for visual observation, on the other hand by the spectroscope of telescope, photoelectric transfer is imaged at again
Sensor（Also known as detector）On, supplied for electronic reading.Because the bar pattern that each producer's scale is encoded is different, therefore bar code mark
Chi is typically unable to intercommunication and used.When being measured using traditional levelling staff, electronic level can also be as common automatic peace
Flat spirit level is equally used, but measurement accuracy at this moment is less than the precision of electronic surveying, particularly precise electronic spirit level, by
In no optical micrometer, as common automatic compensated level in use, its precision is lower.
Current electronic spirit level employs three kinds of autoelectrinic number reading methods for differing larger in principle：1）Correlation method（Come
Block NA3002/3003）2) geometric method（Zeiss DiNi10/20）3) phase method（Open up general health DL101C/102C）.It and traditional instrument
Device, which is compared, following characteristics：
1) reading is objective.In the absence of error, misdescription problem, without artificial error in reading.
2) precision is high.Sight is high and stadia reading is all to be averaged to draw after processing using a large amount of bar code collimator graduation images
, therefore weaken the influence of Staff's carving error.Most instruments, which have, carries out the function that multiple reading is averaged, and can weaken
External condition influences.Unskilled operating personnel's industry can also carry out high-acruracy survey.
3) speed is fast.Due to eliminating count off, listen note, the scene time calculated and artificially malfunction resurvey quantity, survey
The amount time can save 1/3 or so compared with traditional instrument.
4) efficiency high.Need to only focus just can alleviate labor intensity with button with automatic reading.Sighting distance can also be remembered automatically
Record, is checked, and is handled and can be inputted electronic computer and post-processed, can solid line indoor and field integration.
Determine the measurement work of ground point elevation, the referred to as measurement of higher degree.The measurement of higher degree be again three groundworks of measurement it
One.According to the difference using instrument and Metrical Method, the measurement of higher degree can be divided into the measurement of the level, trigonometric levelling and air pressure elevation
Measurement.Elevation is measured with spirit level, the referred to as measurement of the level, it is the most frequently used, most accurate method in the measurement of higher degree.
The general principle of the measurement of the level provides " horizontal line of sight " using spirit level, measures the point-to-point transmission discrepancy in elevation, so that by
Known point height extrapolates unknown point height.
At present, generally elevation is measured with high differentiation.If the elevation of known A points, the elevation of B points to be determined, then exist
、Two rulers of setting on 2 points, and、A frame is disposed to obtain the instrument of horizontal line of sight between 2 points.Assuming that level
Position readings of the horizontal line of sight of instrument on ruler are respectivelyChi（Backsight）Reading is,Chi（Forward sight）Reading is, then、Depth displacement between 2 points（The abbreviation discrepancy in elevation）For
（1）
ThenThe elevation of pointFor
（2）
（3）
The continuous measurement of the level.In the actual measurement of the level, A, B point-to-point transmission discrepancy in elevation are larger or apart from each other, dispose a water
Quasi- instrument can not determine the discrepancy in elevation between 2 points.Now it is necessary to set up several necessary temporarily vertical chis along A, B leveling line
Point, i.e. turning point（As elevation transference）.Spirit level is continuously disposed in the middle of two vertical chis according to the principle of the measurement of the level successively
To determine the discrepancy in elevation between adjacent spots, summation obtains the high difference of A, B point-to-point transmission.
In the high differentiation that measurement elevation is used at present, because spirit level instrument height is unknown, 2 points of height is measured every time
Path difference must all set up spirit level between two points to measure 2 points of staff reading, and such measurement efficiency is restricted.
