Displacement measurement system and measurement method thereof

Abstract

The invention relates to a displacement measurement system and a measurement method thereof. The displacement measurement system comprises a microprocessor, and a display device and a keyboard connected with the microprocessor. The display device comprises designating symbols, a displacement measurement direction choice box which is used for choosing displacement measurement directions, a displacement measurement error compensation value setting box which is used for simultaneously displaying and setting displacement measurement error compensation values of a plurality of interval measured values, and a displacement measurement error compensation characteristic curve box which is used for displaying the coordinate corresponding relation between the displacement measurement error compensation values and the corresponding interval measured values in the displacement measurement error compensation value setting box. The displacement measurement system displays the coordinate corresponding relation between the plurality of the interval measured values and the displacement measurement error compensation values in the selected displacement measurement direction in the form of graphs. Particularly when a LCD display is used, the visual effect of the LCD screen makes the relation more directviewing, and therefore the setting of the displacement measurement error compensation values becomes more reliable.

Description

technical field [0001] The invention belongs to the field of precision displacement measurement, in particular to a displacement measurement system and a measurement method thereof. Background technique [0002] The displacement measurement error compensation value is used for error compensation of the measurement value of the displacement measurement system. How to accurately and reliably set the displacement measurement error compensation value stored in the displacement measurement system plays an important role in ensuring the measurement accuracy of the displacement measurement system. At present, the display and setting of the displacement measurement error compensation value are performed through the display unit and the key unit in the displacement measurement system. For example, US Pat. No. 4,225,931 describes a linear displacement measurement system, wherein a display unit displays the displacement measurement error compensation values ​​stored in the system in d...

AI Technical Summary

Problems solved by technology

However, the system displays a single displacement measurement error compensation value through the display unit of its linear displacement measurement results, and cannot simultaneously display the displacement measurement error compensation values ​​of multiple interval measurement values, so it is not convenient for the operator to adjust the displacement measurement error compensation value. make settings

In addition, the display unit cannot intuitively reflect the coordinate correspondence between multiple displacement measurement error compensation values ​​and the corresponding interval measurement values, so that the operator cannot reliably and accurately set the displacement measurement error compensation values

When the operator mistakenly sets a certain displacement measurement error compensation value, he misses the opportunity to change it in time because he cannot intuitively see the change of this relationship, thus reducing the measurement accuracy of the displacement measurement system
