A Method of Dynamically Eliminating Interference of Quincunx Pointer

Abstract

A method for dynamically eliminating the interference of plum blossom pointers in the present invention, comprising S1, extracting N laser pulses before meter calibration, and calculating the average time of each laser pulse; S2, performing meter calibration operations, using the time of each laser pulse The average time is used as the dynamic pulse calibration time, and the time of each laser pulse in the first second after meter calibration is obtained and compared with the dynamic pulse calibration time, and the laser pulse is corrected according to the comparison result; S3, the last laser pulse in the previous second is used as the starting point, back Extract N laser pulses, calculate the average time of each laser pulse in the previous second; S4, the average time of each laser pulse in the previous second is used as the dynamic pulse calibration time, and obtain the time of each laser pulse in the next second and compare it with Dynamic pulse calibration time comparison, correcting the laser pulse according to the comparison result; S5, judging whether the meter calibration operation is completed, if not, enter S3; if yes, end. The invention can dynamically eliminate the disturbance to the calibration of the meter when the water meter is held in hand or bubbles appear.

Description

technical field [0001] The invention relates to the field of water meter calibration, in particular to a method for dynamically eliminating interference of plum blossom pointers. Background technique [0002] In the process of using the automatic meter calibration machine to calibrate the meter, because it is difficult to fill the water meter with water, there will be air bubbles in the place where there is no water, and a large part of the air bubbles will adhere to the plum blossom of the water meter On the pointer, this causes the laser to scatter when reading the pulse number, and leads to inaccurate reading of the pulse number. In addition, in the process of meter calibration, the calibration personnel need to take down the calibrated water meter by hand, and in the process of taking it by hand, the hand will inevitably block the laser and cause the laser to miss the number of pulses. Since the above two reasons will interfere with the accuracy of the meter calibration...

[0002] In the process of using the automatic meter calibration machine to calibrate the meter, because it is difficult to fill the water meter with water, there will be air bubbles in the place where there is no water, and a large part of the air bubbles will adhere to the plum blossom of the water meter On the pointer, this causes the laser to scatter when reading the pulse number, and leads to inaccurate reading of the pulse number

In addition, in the process of calibrating the meter, it is necessary for the calibration personnel to take down the calibrated water meter by hand, and in the process of taking it by hand, the hand will inevitably block the laser and cause the laser to miss the number of pulses.
