Abstract
The invention relates to an intelligent card-type water meter, which comprises a gear-type movement and a frame, wherein it comprises a gauge pick-up element, an intelligent card charge element, an electrical valve and a control circuit. It has high accuracy, stable property and safe application.
Description
Technical field
The present invention relates to a kind of intelligent card type water meter.
Background technology
The water meter of commonly using easily take place to leak copy, mistake is checked meter phenomenon, inconvenience management, and all be first water, paying in the back, does not meet modern society's demand.
Summary of the invention
Problem to be solved by this invention is to overcome the above-mentioned defective of aforementioned existence, and a kind of intelligent card type water meter is provided.
The present invention solves its technical matters and takes following technical scheme to realize, a kind of intelligent card type water meter, comprise: gear type metering movement and housing, it is characterized in that: also be provided with pick-up part, charging parts and electrically operated valve and control circuit, pick-up part is formed at the tongue tube below this small magnet on the housing by small magnet on the tens gear that is located at gear type metering movement with the securing member sealing and fixing; The charging parts are core with the single-chip microcomputer, have water yield value and cipher memory unit, preserve prepaid in addition and promptly allow the smart card of water value and be arranged on corresponding deck on the housing; Electrically operated valve is made up of with ball valve that is fixed on its output shaft and the position control dish that small magnet is housed the motor of band wheel box, the electrically operated valve control circuit is a bridge switching circuit, each cross-over connection of its double input end have with the position control dish on the tongue tube of the relative adapted of small magnet, and receive smart card single-chip microcomputer two output ports respectively.
By above technical scheme as can be known, the present invention has following advantage: accurate measurement, and reliable and stable, safe in utilization, meet the demand of using behind modern society's post-pay paystation.
