Abstract

The invention discloses an intelligent electronic water meter control system based on a voltage-stabilization type logic gate protection circuit. The intelligent electronic water meter control system is mainly composed of a hall element, a signal processing unit, a one-chip microcomputer and display. The intelligent electronic water meter control system is characterized in that a logic gate protection circuit is connected between the signal processing unit and the one-chip microcomputer; the hall element is composed of a hall sensor a and a hall sensor b which are both connected with the signal processing unit; and the signal processing unit is composed of a three-terminal signal amplification circuit connected with the hall sensor a and the hall sensor b, and a low-pass filter circuit connected with the three-terminal signal amplification circuit and the one-chip microcomputer. The intelligent electronic water meter control system can accurately measure the flow of water flowing through the water pipe, and therefore the intelligent water meter is accurate in measurement and clear in measurement display, and the meter reader can read the meter more accurately.

Description

Technical field [0001] The invention relates to the technical field of electromechanical equipment, in particular to an intelligent electronic water meter control system based on a voltage-stabilizing logic gate protection circuit. Background technique [0002] In daily life, the water meter is mainly used to record the water consumption of tap water. The traditional mechanical water meter is installed on the water pipe and displays the passing water flow through the rotation of the pointer or the word wheel on the meter. The existing rotary-wing mechanical counting water meter has a drawback, that is, it is inconvenient and unintuitive to read the meter, and the pointers of the pointer-type water meters are misplaced, resulting in false readings. Although the direct-reading method has been improved, there are cases where half of a word appears when the word is skipped. After the disk surface of the mechanical water meter is rusted or fogged, the measurement display is not clear,...
