Description

Numeral display panel micrometer frame of reference
Technical field
This novel digital display panel micrometer frame of reference that carries out high-accuracy micrometer reading that is particularly related to fields of measurement such as being applied to national primary levelling, building engineering survey and settlement measurement.
Background technology
The micrometer frame of reference of the present general high-accuracy automatic compensated level that uses, all be to adopt the micrometer handwheel to drive guide rod to move, drive the dull and stereotyped rotation of micrometer by the driving head that is contained on the guide rod again, from eyepiece, read the reading that is contained in the micrometer on the guide rod, obtain the variation of the elevation of institute's micrometer.There are two errors in such system: the dull and stereotyped rotational angle of the first is converted into straight line on the micrometer and moves that can to produce row poor; It two is that human eye can produce pointing error when reading reading on the micrometer.
The utility model content
This novel purpose is to propose a kind of digital display panel micrometer frame of reference, pointing error when it can effectively be eliminated row difference that traditional Anping spirit-leveling instrument micrometer frame of reference exists and observe micrometer with eyepiece, and can show directly that on display screen the discrepancy in elevation changes, and intuitively easy, the precision height.
For realizing above-mentioned novel purpose, this is novel to have adopted following technical scheme:
A kind of digital display panel micrometer frame of reference, comprise the micrometer flat board and the drive unit thereof that are connected with apparatus subject, it is characterized in that, described micrometer frame of reference also comprises scrambler, data processing unit and the display unit that changes in order to the dull and stereotyped angle of monitoring micrometer, and described scrambler is connected with data processing unit respectively with display unit.
Further, the dull and stereotyped drive unit of described micrometer comprises the micrometer handwheel that is connected with apparatus subject, and this micrometer handwheel and micrometer sheet glass are in transmission connection.
Preferably, described micrometer handwheel is in transmission connection by fluted disc and the micrometer flat board that cooperates with the micrometer handwheel.
More preferred, described fluted disc is set in the fluted disc rotating shaft, and this fluted disc rotating shaft is fixedlyed connected with apparatus subject, and described fluted disc is fixedlyed connected with the micrometer flat board.
Also be arranged with elastic spring in the described fluted disc rotating shaft, this elastic spring is arranged between fluted disc and the apparatus subject.
Described scrambler is connected with apparatus subject by web joint, and the rotating shaft of scrambler passes apparatus subject and be connected with the scrambler axle sleeve, and the scrambler axle sleeve is fixedlyed connected with the micrometer flat board.
Described display unit adopts display screen, its be arranged on apparatus subject on cover.
Described micrometer frame of reference also comprises battery case, and this battery case is connected with apparatus subject.
This is novel to be contained in micrometer handwheel on the apparatus subject by adjusting, drive the micrometer flat board and rotate the variation of generation angle together, the rotation of micrometer flat board also can cause the skew of collimation line, the variation that makes the observed target of spirit-leveling instrument produce an elevation, scrambler reads aforementioned angle changing value and is converted into digital signal, digital signal is handled through data processing unit and is produced altimetric reading, directly shows through display unit again.
Compared with prior art, this novel advantage is: this numeral display panel micrometer frame of reference be convenient to operation, intuitively easy, precision is high, pointing error in the time of can effectively eliminating row difference that traditional Anping spirit-leveling instrument micrometer frame of reference exists and observe micrometer with eyepiece is suitable in field widespread uses such as measurement of the level, building engineering survey and settlement measurements.
