Description
Technical field
The invention belongs to the earth and engineering measuring technology field more particularly to a kind of composite level levels easy to operate
The accurate calibration method of device.
Background technology
Traditional leveling device is made of a spirit level and two levelling staffs.First by two level marks when measurement
Ruler is respectively placed in A, B on ground at 2 points, then spirit level is arranged in the centre position of 2 points of A, B, in order to ensure measurement accuracy,
Generally require horizontal distance of the spirit level away from two levelling staffs equal or roughly equal.It is regarded using the level of spirit level after leveling
Line sights the absolute altitude numerical value for reading two levelling staffs respectively, and the difference of the high numerical value of institute's mark is the level height of 2 points of ground A, B
Difference, if known elevation wherein, you can extrapolate the elevation of another point by height difference.Traditional leveling device and corresponding
Operational method exist it is following insufficient：（1）3 points of configurations, asynchronous observations, it is low to measure working efficiency.Because in complicated landform ring
The reasonable disposition of position between 3 points of spirit level and levelling staff is realized in border, often expend a large amount of energy of survey crew and when
Between, while the asynchronous observation for successively sighting scale observed reading respectively increases observation time again, affects the measurement of the level
Working efficiency, and when encountering the complicated landforms environment such as abrupt slope, hollow, pool, irrigation canals and ditches, gully, rivers, mountain area, often not
Spirit level can be erected to the centre position of two levelling staffs, cause the measurement of the level that can not implement.（2）Single observation system is surveyed
It is low to measure reliability.I.e. traditional leveling device is measured only with a spirit level, cannot to the height difference data of measurement into
The reliability of the more observation systems of row checks, and generally for the reliability for improving the measurement of the level, often checks mould using round-trip measurement
Formula, it is same to expend a large amount of energy and time of survey crew, influence the working efficiency of the measurement of the level.In order to overcome traditional level to survey
The deficiency of device is measured, the Chinese patent that number of patent application is 201220611636.6 discloses a kind of " dual formula observation ruler instrument
Unify composite level "（Hereinafter referred to as composite level）, structure is provided with cylindricality ruler body and spirit level, in cylindricality ruler body
The levelling staff parallel with cylindricality ruler body axis is fixed on same cylinder and the observing unit that can slide up and down, the observation is single
Member has the other side's altitude signal analyzer being mutually permanently connected and our altitude signal analyzer, other side's altitude signal analyzer
Collimation axis is vertical with cylindricality ruler body axis.When the measurement of the level, need cylindricality ruler body（Levelling staff）Lower end be placed in auxiliary scale
On pad, while needing to fix cylindricality ruler body using three legs and feet framves（Levelling staff）, by observing spirit level etc. by cylindricality ruler body（Water
Fiducial mark ruler）It after leveling, then is observed ....This patent application is into beans-and bullets shooter：Spirit level is placed in levelling staff for the first time
On, the integration of spirit level and levelling staff is realized, antithesis Observation principle can be used, by 3 points of traditional leveling device
Configuration is changed to 2 points of configurations, and realizes the simultaneous observation of dual system, and existing traditional measurement of the level dress is overcome from principle
Set existing deficiency.
Since the spirit level collimation axis of composite level is vertical with scale, thus composite level spirit level it is accurate whether it is straight
The horizontality of the plumbness for influencing scale and spirit level collimation axis is connect, therefore the horizontality of spirit level collimation axis must reach
The requirement flat to spirit level automatic compensator coarse adjustment.However, so far, there is no be suitble to the spirit level of composite level accurate
Calibration method.
