Abstract

The invention relates to an intelligent water meter. The intelligent water meter comprises a control module, a storage module, a digital-analog conversion module, a display module and a clock module, wherein the storage module consists of a storage device and a hardware multiplying unit; the control module comprises a signal transmitting base meter, a control valve and a CPU (central processing unit); the signal transmitting base meter transmits information to the CPU; running and stopping of the water meter are controlled by the control valve under the control of the CPU; various types of information is stored in the storage device in a processing process; data in the storage device are guided in the hardware multiplying unit; signals are converted by the digital-analog conversion module and are displayed through the display module; the display module has a water using data transmitting and settlement bargain function; the clock module provides recurrent pulses for a singlechip and comprises an inner DCO (data clock output) clock and two other external clocks which can be a clock or standard crystal oscillator and a crystal oscillator with the highest clock frequency of 8MHz respectively.

Description

A kind of intellectual water meter

Technical field

The present invention relates to a kind of intellectual water meter, particularly relate to a kind of convenient intellectual water meter regulated.

Background technology

Intellectual water meter a kind ofly utilizes modern microelectronic technology, Modern Transducer Technology, intellective IC card technology to measure water consumption and carry out reportedly passing with water number and the new water meter of settlement bargain, every household can easily be allowed so conveniently to inquire about water consumption, also can conveniently pay the fees, the intellectual water meter in market is also all so substantially, there is some fault when causing water meter to quit work in some intellectual water meters, the storage degree of water meter and precision, inquiry water meter various aspects of performance is short of all to some extent.

Summary of the invention

Technical matters to be solved by this invention is: provide a kind of intellectual water meter, and described intellectual water meter has the effect measuring effect, inquiry facility and remote control accurately.

For solving the problem, technical scheme of the present invention is a kind of intellectual water meter, it comprises control module, the storage module be made up of reservoir and hardware multiplier, D/A converter module, display module, clock module, described control module comprises sender base table, by-pass valve control, CPU, sender base table sends information to CPU, CPU by-pass valve control controls using and closing of water meter, in processing procedure by various information storage in reservoir, data in reservoir import in hardware multiplier subsequently, signal is changed by D/A converter module, shown by display module, described display module has reportedly to be passed and settlement bargain function with water number, described clock module provides recurrent pulse for described single-chip microcomputer, comprise internal DC O clock and two other external clock, outside can connect two clocks, one can connect clock and watch crystal oscillator or standard crystal oscillator, another connects the crystal oscillator that maximum clock frequency is 8MHz.

Further, described water meter is provided with timer, and described timer has two interrupt vectors, is convenient to process various Interruption.

Further, described timer has acquisition mode, realizes various measurement and conversion by the capturing function of timer.

Further, described D/A converter module is integrated with 12,14 tunnel A/D by single-chip microcomputer, and each road conversion in 14 tunnels has a controllable conversion reservoir.

Further, described clock module is provided with a control register, and described control register writes the clock that corresponding control bit just can produce needs.

Compared with prior art, the present invention is provided with clock module on water meter, connects the measurement that can control water meter with external method more accurately in employing, is provided with timer simultaneously and also can ensures that data are preserved and simple operation when breaking down on water meter.
