Embodiment 3

[0049] In the third embodiment, the non-circular metal sheet is a 270° metal sheet, and the six secondary coils are divided into three pairs connected in series and anti-phase.

[0050] The method for eliminating data jitter caused by water quality in the water meter of this embodiment comprises the following steps:

[0051] S01. The vibration sensor deployed in the water meter regularly acquires the vibration data of the non-circular metal sheet, which is represented by a variable s; the vibration data refers to any item of the displacement or angle of the non-circular metal sheet from the initial position. In this embodiment, the vibration sensor deployed in the water meter acquires the vibration data s=1° of the non-circular metal sheet at a certain moment.

[0052] S02. Compare the vibration data s with the preset water quality impact threshold range S 0 and S 1 , if S 0 1 , it is determined that the vibration of the non-circular metal plate of the water meter is caused...

Abstract

The invention discloses a water meter capable of eliminating data jitter caused by water quality. A method for eliminating data jitter caused by water quality comprises the following steps: acquiringvibration data and judging whether vibration is caused by water quality or not; acquiring induced voltage difference data of each secondary coil pair at a current moment and a previous moment, and calculating jitter reference values accordingly; and calculating a cycle length correction value according to a current cycle length and the number of jitter reference values being equal to 0. Through adoption of the method and system disclosed by the invention, the technical problem that data jitter caused by water quality cannot be eliminated in an existing coil inductive water meter is solved.

Description

technical field [0001] The invention belongs to the technical field of water meters, in particular to a water meter capable of eliminating data jitter caused by water quality. Background technique [0002] At present, water meter measurement mostly adopts dry reed switch, Hall element, and Wiegand sensor, but due to the inherent mechanical characteristics, service life and vibration resistance of the dry yellow tube, the Hall element has too much current, and there are also low or low The frequency response problem of high flow rate; the Wiegand sensor has the disadvantage of large magnetic resistance, which is very easy to absorb the impeller to increase the starting flow, and the price is expensive. Therefore, the existing remote water meter adopts the principle of non-coil induction to convert the rotation of the mechanical watch gear or the rotation of the pointer into an electric pulse signal. For example, Chinese patent CN201810125788. type angle sensor, such as figu...
