Signal transmission and metering algorithm for impeller magnetic inductive basic water and heat meter

Abstract

The invention discloses a signal transmission and metering algorithm for an impeller magnetic inductive basic water and heat meter, wherein magnetic materials are used to make a meter shell (1), a core is installed in the meter shell (1), an impeller (15) which is made from metal or non-metal is upwards assembled from a bottom end of an impeller box upper body (4), an impeller box lower body (19) is fixedly arranged at the bottom of the impeller box upper body (4), and one or a plurality of circuit boards (5) with magnetic induction sensors is / are fixedly arranged at the center of the external top of the impeller box upper body (4); and the signal transmission and metering algorithm stores the function generatrix in a computer which calibrates the basic meter, the minimum flow (q1), the critical flow (q2), the common flow (q3), the maximum flow (q4) and other feature points of the basic meter are only needed to be calibrated through the function generatrix when the basic meter is calibrated, so the (m--tau) function data which is similar to the function generatrix can be obtained, and accordingly, the metering of the basic base can be more accurate.

Description

Technical field: [0001] The invention belongs to the electronic transmission and measurement algorithm of the base meter of the water meter and the heat energy meter, in particular to a signal transmission and measurement algorithm of the impeller magnetic induction water meter and the base meter of the heat energy meter. Background technique: [0002] At present, most of the base meters used to manufacture smart water meters and heat meters are base meters that use mechanical transmission or ultrasonic waves. The measurement of these base meters is achieved by rotating gear meshes to form decimals and periodically emitting ultrasonic signals. Yes, these base meters either have low measurement accuracy or insufficient low flow sensitivity during measurement. [0003] The invention provides a solution, which can greatly improve the measurement accuracy of intelligent water meters and heat meters. Invention content: [0004] The present invention is realized like this: it i...
