Abstract

The invention discloses a coil induction type water meter capable of identifying interference and a position. A method for identifying the interference and the position by the coil induction type water meter comprises the following steps of: acquiring induced voltage difference data and calculating a voltage difference measured value; generating segmented voltage difference vector sequences; calculating distances among the voltage difference vector sequences; and judging whether the water meter is interfered and identifying an interference position. The method and a system which are disclosedby the invention solve the technical problem that an existing coil induction type water meter cannot identify the interference and the interference position.

Description

technical field [0001] The invention belongs to the technical field of water meters, in particular to a coil induction water meter which can identify interference and position. 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 angular position sensor, w...
