The advanced capacitive gate type digital display height measurement instrument disclosed by the invention is rapid, precise and intellectualized in operation and especially can be used for carrying out temperature compensation and used for reducing measuring errors, thereby meeting high-end application requirements in the technical field of engineering.
Description
Technical field
The invention belongs to the measurement component core technology field of numerical control measurer, the capacitance-grid type digital that relates in particular to a kind of temperature compensating type shows elevation measurement equipment.
Background technology
Capacitor grid transducer can be realized the measurement of straight-line displacement and angular displacement, can be divided three classes: straight line capacitor grid transducer (the long grid that hold), its whole sensor is made up of placing two groups of strip shaped electric poles faciations, one group is moving grid, another group is fixed grid, and moving grid and fixed grid are realized the measurement of its displacement by electrostatic coupling; Circular capacitor grid transducer (the sheet circle holds grid), it has plated a plurality of radial electrode groups in the substrate of disc insulating material, and the electrode group on two coaxial discs is corresponding, and the capacitive coupling situation has reflected the counterrotating angle of two disks; Tubular capacitor grid transducer (the column circle holds grid), it is made up of two coaxial cylinders that are nested together, and electrode is plated on the cylinder, can realize measurement of length.
The open long know-why of holding grid of prior art: carry out position measurement with the displacement differential change by electric capacity.In the prior art, long capacitive grid type digital display altimeter generally adopts capacitive transducer, is made of fixed grid and two fundamental measurement elements of moving grid.
Prior art discloses the design of fixed grid: on the strip metal surface of long 320mm, wide 50mm, make uniformly-spaced the also rectangular electrodes of mutually insulated along direction of measurement with photoetching method, these electrodes and insulation on every side.These electrodes on the fixed grid are transfer electron.
It is the moving grid of 4mm that prior art also discloses adjacent electrode centre distance, and its two-sided copper clad plate by 50mmX40mm is made, and one side is an electrode, and another side is the line of P.e.c..Parallel with the fixed grid transfer electron on moving grid, the width of arranging successively is 64 strip electrodes of 0.5mm and mutually insulated.
Whenever 7 bindings of being separated by become electrode on the same group together, totally 8 groups, 8 adjacent successively supply electrodes are abbreviated as 8 supply with electrodes.Strip electrode perpendicular below 64 supply electrodes is receiving electrode.8 are supplied with electrodes is a power-up period, supplies with phase differential respectively and be 45,90,135,180,225,275,315,360 reference voltage, and making adjacent two service voltage phase differential of supplying with on the electrodes is 45.
Coupled relation between fixed grid and the moving grid is that 8 on the moving grid supply with the pitch that electrode covers transfer electron on the fixed grid, decide that transfer electron designs longlyer on the cupboard, also cover receiving electrode in the supply electrode on covering moving grid. supply with electrode during work by power electronics, by the electric capacity electrostatic coupling, on the transfer electron on the fixed grid, inducing electric charge. transfer electron is again by a capacitive coupling, the electric charge of inducting is transferred to receiving electrode, and signal is supplied with electronic circuit after amplifying.Take out the one-period of supplying with signal, supply with cathode lead with preceding 4 and merge into a pole plate, back 4 supply cathode lead are merged into another pole plate, and a transfer electron guide card on the fixed grid is a tri-electrode, it is waited be all receiving electrode.
How on existing capacitive grid numeral display altimeter basis, moving grid and the fixed grid that Application and Development is new relates to, sensor, single-chip microcomputer, this makes prior art need develop a kind of physical construction of digital display altimeter, and introduces giant-screen digital display assembly or quick measurement pattern start assembly.
Recently, abroad occurred carrying out plane, parallel surface and face of cylinder solid inside dimension, outside dimension, highly, the degree of depth or apart from the novel high surveying instrument of dimensional measurement, it can carry out one dimension or two-dimensional measurement, can search for the summit of hole or axle automatically, difference in dynamic instrumentation between record maximum, minimum value and the maximin is calculated, deviation and runout errors such as all right measuring vertical degree, linearity, the depth of parallelism, and with ISO1101 standard output data.But identical with existing procucts, this class new product does not have digital display screen yet, the not quick start assembly of measuring, the position probing scrambler more is not set, from programming Control assembly etc., all can't realize high-precision rapid survey, can't carry out graphical batch processing to measurement data.
In the document of publishing, domestic inventor once disclosed a kind of novel height finder, was adapted at measuring in the forestry trees height.Its ultimate principle is that the principle design by any similar triangular form forms.It is characterized in that not need measurement level distance, and is not subjected to the restriction of topographic condition.Its altimetry precision is within ± 3%, and the survey high-level efficiency is 2.5 times of Bo Lulai height finder.When using, only need to establish one 2 meters absolute altitude, at the arbitrary measuring point in 10～40 meters scopes of trees level distance at the trunk of measured tree, by instrument aiming absolute altitude, the stop place of balancing point when tree base or treetop, mobile movable scale can be determined the height of trees from fixing index dial.This technology is not suitable for being applied to the survey height of field of engineering technology, and measuring accuracy is too low, and application is too narrow, and most assemblies of the present invention all do not have to use on this trees altimeter.
The Korea S inventor once delivered a kind of device for measuring height of object, and it has two acousto-optic modules, reflects the light that emits from optical transmitting set with the predetermined refraction that depends on frequency modulation, thereby light is throwed along the X-axis and the Y-axis of object; This technology also comprises respectively two other acousto-optic module with the signal Synchronization of two the acousto-optic modules in front, makes from the light of object reflection to focus on the optical pickup apparatus.The change of object height is with regard to measured come out according to the variable in distance between the center that focuses on the position of the luminous point on the optical pickup apparatus and optical pickup apparatus.High principle of the survey of this technology and component design are different fully with the present invention.
Day inventor delivered a kind of can be when confirming that the position of gauge head with determinand concern, the height measurer that moves with light posture.Its inventive point is: in the side of and adjacency relative with the face of the gauge head with pillar and near base, be provided with handle, the air come-up gauge tap that the air that is provided with subtend air levitating device on this handle is supplied with, blocking is controlled, repeat switch, cancellation switch etc.Inventive point of the present invention is different fully with the prior art, and inventive point disclosed by the invention is not delivered by the prior art and other documents.
In a word, characteristics of the present invention are to overcome the deficiencies in the prior art, develop a kind of quick, accurate, intellectualized operation.Especially can carry out temperature compensation, change and subtract the senior capacitive grid type digital display height-gauge of measuring error, thereby satisfy the high-end applications demand of field of engineering technology.
