Abstract
The adjusting method guarantees the consistency distance measurement capability of visibility appearance. Set appearance under the working station, put light blocking plant at the port of receiver parts to completely keep out conceivable dispersion signal to enter receiver, observe the instrumental signal export and adjust inside the zero warp limit. Put standard adjusting plant at the middle section of the project beam of light and incept beam of light as an original test benchmark, observe the instrumental signal export to accord with the manufacture criterion. If the manufacture adjusting plant capability overtops the limit, return or instead a new manufacture adjusting plant until the instrumental signal export accord with the manufacture criterion; if the manufacture adjusting plant capability is eligible, print the fact export on the manufacture adjusting plant, and the demarcation finished. It enhances the consistency of distance measurement capability of visibility appearance, reduces the produce cost and buildups the market competition of visibility appearance.
Description
Technical field
The present invention relates to a kind of calibration steps that guarantees visibility meter range performance uniformity, be used for visibility measurement, belong to the meteorological field of engineering technology of atmospheric optics.
Background technology
For same weather conditions, the result that the visiometer of same model is measured should be identical, and its discretization error is called the consistance of instrument.External visiometer consistency of product index is about 4%, and domestic visiometer consistency of product index may surpass about 10%.Causing the excessive main cause of product range performance dispersion degree is that product fails well to be calibrated in process of production.And the bad reason of product calibration, the one, correcting device is undesirable, and the 2nd, calibration steps is not right.
Summary of the invention
At the problems referred to above, the object of the present invention is to provide a kind of calibration steps that guarantees visibility meter range performance uniformity, with under the suitable situation of correcting device performance, improve visiometer range performance coincident indicator.
For achieving the above object, technical scheme of the present invention is, a kind of calibration steps that guarantees visibility meter range performance uniformity is provided, and the calibration steps step is as follows:
(1) make instrument in running order, at first carry out the high-visibility end calibration of instrument, stifled tabula rasa is placed to receiver component port place, block the scattered signal that may enter receiver fully, whether the signal output of optical viewer meets the requirement of product specification regulation, whether the signal output that is instrument is positioned within the instrument regulation zero deviator tolerance limit, if the output of the signal of instrument does not meet the product specification requirement, need to adjust equipment circuit zero point drift, meet the requirement of product specification regulation up to signal output;
(2) the standard calibration plate as the original measurement benchmark being placed to the cross middle section of body of emission light beam and receiving beam locates, whether the signal output of optical viewer meets its calibration value requirement, if the output of the signal of instrument exceeds tolerance limit, then need adjust Instrument working parameter, change the circuit enlargement factor, meet the product specification requirement up to signal output;
(3) take off the standard calibration plate, load onto into the product calibration plate, leave the instrument light path, whether the signal output of optical viewer meets the product specification requirement, promptly the calibration value with the standard calibration plate close, within product calibration plate performance (equivalent scattering coefficient) tolerance limit, exceed tolerance limit as fruit product calibration plate performance, then the product calibration plate that need reprocess or more renew meets the product specification requirement up to signal output; Qualified as fruit product calibration plate performance, its actual output seal can be write on the product calibration plate, the product calibration plate is demarcated and is finished.
The essence of calibration is the transmission of original measurement benchmark to product, and the original measurement benchmark is set up and demarcated by higher grade benchmark, and secondary benchmark and even product calibration reference---product calibration plate is by being demarcated with the comparison of primary standard.The present invention has provided the method that the product calibrating installation is demarcated, and the mode of master reference and secondary benchmark foundation is provided, and has provided the visiometer calibration means of discretization error minimum.Evidence according to method of the present invention, can guarantee that the consistency of product index reaches 3%, reaches advanced world standards.Use this method, can improve consistance, reduction visiometer production cost of products, the enhancing visiometer competitiveness of product in market of visiometer product range performance.
Embodiment
The light path layout of visiometer changes, optical property departs from, the parameter difference of electronic devices and components etc., all can influence the accuracy and the consistance of properties of product, therefore, in particularly last the debuging in the operation of visiometer production, must calibrate.The task of visiometer production phase (when debuging) calibration has two: the one, guarantee to produce the satisfactory product of range performance consistance; Two provide and the supporting calibration plate of payment at random with definite performance of product.
The calibration steps step is as follows:
(1), make instrument in running order, at first carry out the high-visibility end calibration of instrument, stifled tabula rasa is placed to receiver component port place, block the scattered signal that may enter receiver fully, whether the signal output of optical viewer meets the requirement of product specification regulation, whether the signal output that is instrument is positioned within the instrument regulation zero deviator tolerance limit, if the output of the signal of instrument does not meet the product specification requirement, need to adjust equipment circuit zero point drift, meet the requirement of product specification regulation up to signal output;
(2), the standard calibration plate as the original measurement benchmark being placed to the cross middle section of body of emission light beam and receiving beam locates, whether the signal output of optical viewer meets its calibration value requirement, if the output of the signal of instrument exceeds tolerance limit, then need adjust Instrument working parameter, change the circuit enlargement factor, meet the product specification requirement up to signal output;
(3), take off the standard calibration plate, load onto into the product calibration plate, leave the instrument light path, whether the signal output of optical viewer meets the product specification requirement, promptly the calibration value with the standard calibration plate close, within product calibration plate performance (equivalent scattering coefficient) tolerance limit, exceed tolerance limit as fruit product calibration plate performance, then the product calibration plate that need reprocess or more renew meets the product specification requirement up to signal output; Qualified as fruit product calibration plate performance, its actual output seal can be write on the product calibration plate, the product calibration plate is demarcated and is finished.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
