Method for automatically correcting difference of meter calibration machines by means of comparison

Abstract

The invention provides a method for automatically correcting difference of meter calibration machines by means of comparison. The method includes placing water meters calibrated by an optional meter calibration machine in specified regions of assembly lines and reading water meter parameters calibrated by the meter calibration machine before the meter calibration machine is triggered; storing theread water meter parameters at specified locations of software; randomly extracting at least one water meter from an optional specified region of the assembly lines during each re-inspection, re-inspecting the water meters in the other meter calibration machines, and automatically uploading re-inspected water meter parameters to other specified locations of the software; comparing the re-inspectedwater meter parameters to the water meter parameters read by the software to obtain comparison data of the diversified water meter parameters between the various meter calibration machines; arbitrarily selecting a meter calibration machine to be used as a standard station, acquiring difference values of the standard station and the other meter calibration machines from the comparison data and automatically correcting the difference of the other meter calibration machines by the aid of the difference values. The method has the advantages that the difference can be automatically timely corrected by the aid of the method, and accordingly the efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the field of meter calibration, in particular to a method for automatic comparison and correction of table errors by a meter calibration machine. Background technique [0002] At present, when producing water meters, multiple meter calibration machines are installed on both sides of the assembly line, and before using the meter calibration machines to calibrate the meter, it is usually necessary to check the difference between each meter calibration machine. In the existing technology, when performing the calibration, a stable water meter is firstly taken to the meter calibration machine to be calibrated for repeated testing, and the average value is obtained; then the water meter is taken to the standard platform for repeated testing , to obtain the average value; finally, compare the calibration machine to be calibrated with the average value obtained by the standard station, and if there is an error, manually modify the stag...

Problems solved by technology

However, the existing way of aligning the difference has the following defects: one station is required for comparison and modification, which is not only time-consuming and laborious, but also low in efficiency, which will delay normal production; at the same time, it cannot correct the difference in time, which There may be errors in the actual verification results
