Description

A kind of in-situ calibration device of plumb line coordinator
Technical field
This application involves civil engineering monitoring technical field more particularly to a kind of in-situ calibration devices of plumb line coordinator.
Background technology
Plumb line coordinator is a kind of high-accuracy novel intelligent instrument observed for vertical line, can be by just hanging down or falling Vertical device realizes two-way horizontal displacement automatic measuring, is usually used in Dam, skyscraper, bridge, nuclear power plant containment shell Deformation measurement.Plumb line coordinator according to the difference of operation principle, is divided into condenser type and photo-electric;Wherein, current common main Photo-electric if (CCD) plumb line coordinator.
Photo-electric (CCD) plumb line coordinator is that the contactless automation displacement measurement of one kind realized using CCD device is set It is standby, the displacement of X, Y both direction of vertical line planar can be measured, measuring principle in two directions is identical, measures electricity Road is mutual indepedent, does not interfere with each other.When light beam is pointed into vertical line and CCD, vertical line generates a projection, the pixel of CCD on CCD Light intensity is converted into quantity of electric charge storage.CCD drivers generate respective logic sequential and export charge information, remove signal by whole After shape processing, the coordinate of vertical line is obtained, calculates the shift value of measuring point accordingly, result of calculation can be sent to inspection through communication interface Survey computer or other external equipments.
For photo-electric CCD plumb line coordinators, China only has professional standard at present《Photo-electric (CCD) plumb line coordinator》 (DL/T 1061-2007).The standard has carried out accurate definition to photo-electric CCD plumb line coordinators, specifies associated specifications, Test method, inspection rule and mark, packaging, transport, storage etc..But only to the manufacture of plumb line coordinator in existing standard Scaling method carried out clearly stipulate that but have no the online calibration method after photo-electric CCD plumb line coordinators come into operation, go out Factory's scaling method is for the on-line calibration after equipment investment use and is not suitable for.According to the national requirement in relation to measurement Law, for Workload utensil, using unit should voluntarily periodic verification or give other metering validation activities examine and determine.For above-mentioned vertical line Coordinatograph, with important engineering structure monitor on-line application, once the equipment is installed in place just can not dismantle or dismantle after weight New installation will result in initial deviation.Therefore, how to ensure that these equipment are working properly in the long-term use, steady in a long-term Performance is effectively examined, and is that a technology urgently to be resolved hurrily in this field is asked if carrying out on-line proving to these equipment Topic.
Currently, domestic measuring device tool is in addition to periodical off-line calibration during the calibration of manufacture and use, equipment on-line calibration The technical need task of top priority.For example, the plumb line coordinator involved by nuclear plant safety shell structure barrel distortion belongs to long term monitoring State, equipment can not be by obtaining effective verification offline, and domestic correlation measurement verification/calibration regulation does not also carry out this Regulation.
The basic structure group of plumb line coordinator becomes:In mutually orthogonal X, Y both direction, it is respectively provided with identical structure Displacement measurement system.When plumb line coordinator works, X, Y-axis displacement measurement system measure the displacement in respective direction respectively, Then the specific location of vertical line is calculated according to rectangular coordinate system.Therefore, the calibration of plumb line coordinator is the method for set of system, The accuracy that each axis measures should be calibrated, while whether also to calibrate two axis of X, Y orthogonal.In addition, in the case of at the scene, also want Whether the XY measurements plane for verifying plumb line coordinator is horizontal.It only in this way just can guarantee the accuracy of final measured value.
Therefore, at the scene in the case of when being calibrated to plumb line coordinator, the first step is all that adjust calibration plane horizontal;The Two steps are to be moved calibrating installation by school axis (for example, X-axis) direction along plumb line coordinator, then observe plumb line coordinator another The variation of the data indicating value of an outer axial direction (for example, Y direction).If being basically unchanged of indicating value of Y direction, then it is assumed that should The calibration of axes of calibrating installation is parallel by school axis X with plumb line coordinator;Third step is exactly to be calibrated by school axis according to certain step pitch It is whether accurate.
However, various caliberating devices in the prior art, all there is some following defects and deficiencies:
1) due to measured by plumb line coordinator being displacement data in X/Y plane, to ensure accurately to measure just necessary Ensure that X/Y plane is in level;However, in practical situations, due to equipment assembly technology or the cause for quality of installation, very much The horizontality of the X/Y plane of field erected plumb line coordinator is unable to get guarantee.Therefore, if only caliberating device is adjusted Level does not ensure that calibration plane is parallel with the measurement plane of plumb line coordinator, there is a high likelihood that being the two planes Between there are an angles.In this case, the indicating value variation of caliberating device and the indicating value of plumb line coordinator, which change, is not Synchronous, but there are certain proportionate relationships, and this nonparallelism can not be measured with existing utensil, therefore institute It is actually not rigorous enough that the calibration of progress, which measures,.
2) as previously mentioned, by plumb line coordinator by the variation of another axial data except the axis of school, to ensure to demarcate The calibration of axes of device and plumb line coordinator equally exist aforementioned problem by the parallel method of school axis.According to the adjusting side Method, it is necessary to be provided simultaneously with two preconditions:Precondition one, X-axis and the Y-axis of plumb line coordinator must be orthogonal;Precondition Two, calibration of axes necessarily is in or is parallel to the XY axial planes of plumb line coordinator.But caliberating device in the prior art is not tested Demonstrate,prove the function of above-mentioned two precondition.In addition, using be calibrated equipment it is a certain it is unconfirmed whether the data of accurate axis come The state for verifying another axis is also not rigorous enough, because caliberating device in the prior art cannot exclude plumb line coordinator sheet The non-orthogonal situation of body XY axis (if the XY axis of plumb line coordinator is non-orthogonal, which itself has problem, it is necessary to It carries out carrying out demarcating again after repairing accordingly just significant).
3) caliberating device in the prior art is that the plumb line directly being had by oneself using plumb line coordinator is moved to obtain Obtain change in displacement data.But vertical line slightly stress under the action of plummet just will produce and significantly swing very much.Therefore, into Rower timing, it is necessary to which waiting for could be read after allowing plummet to settle out for a long time, thus lead to the effect of staking-out work Rate is very low, and one plumb line coordinator of calibration generally requires one to two hours.In addition, if site environment is more complicated, example Such as, there is vibration at scene or has the case where wind, then vertical line is difficult to settle out, so that the reading of caliberating device exists very Large deviation.
