Description

A kind of intellectual water meter

The utility model belongs to the tap water resource management with TM card automatic charging and control technology field.

In this allegro life today, people are seeking a kind of simpler and more direct life style faster.Oneself becomes a reality centralized and unified supply tap water, and there are a series of problems such as metering is inaccurate, unreasonable charges in present " the first water; back payment " continued to use and the mode of manually tabling look-up, bring unnecessary trouble for users and water resource management department.Therefore must seek a kind of ideal method, can alleviate the burden of user and administrative authority, can adapt to the needs of current socio-economic development rule again.

Development purpose of the present utility model is developed the civilian intellectual water meter of a kind of novel TM card exactly, thereby realizes payment back water earlier, pays how much management mode with how much water, and reasonable utilization with water resource raises the management level.

The utility model is achieved in that Fig. 1 is a product structure synoptic diagram of the present utility model, and Fig. 2 is a circuit box structure synoptic diagram of the present utility model, and Fig. 3 is the utility model electricity theory structure synoptic diagram.A kind of intellectual water meter by the Single-chip Controlling processing, it is characterized in that, the product structure synoptic diagram has housing 1 among Fig. 1, the shell that top cover 2 and loam cake 3 are formed, pulse input circuit U8 is installed in the right lower quadrant of top cover 2, power supply U9 is installed in the low order end of housing 1, data processor 4 is installed in the latter half of top cover 2, TM card reader U5 is installed in the upper left quarter below the top cover 2, LCD U2 is installed in the middle and upper part below the top cover 2, raise loam cake 3 and can see TM card reader U5 and LCD U2, control motor 5 is fixed on the lower left quarter of top cover 2, water meter 6 is installed in the right middle and upper part of housing 1, motor valve 7 is installed in the left side of housing 1, and 8 is the current inlet port, and 9 is water export.In order better to realize automatic charging and a kind of intellectual water meter of controlling automatically, it is characterized in that, the data processor of forming by single-chip microcomputer U1, data-carrier store U3, warning circuit U4, control circuit U6, electric voltage observation circuit U7 4, and TM card reader U5, LCD U2, power supply U9 and oscillatory circuit U10 etc. partly form, and see Fig. 2.A kind of intelligence for the ease of automatic charging and control is automatically shown, it is characterized in that, pulse input circuit U8 links to each other with single-chip microcomputer U1, TM card reader U5 links to each other with single-chip microcomputer U1, electric voltage observation circuit U7 links to each other with single-chip microcomputer U1, power supply U9 and electric voltage observation circuit U7, control circuit U6 links to each other, control circuit U6 links to each other with single-chip microcomputer U1, data-carrier store U3 and single-chip microcomputer U1 are mutually repeatedly, by G1, C1, the oscillatory circuit U10 that C2 constitutes links to each other with single-chip microcomputer U1, and warning circuit U4 is made of triode P2 and hummer F, and it is linked to each other with single-chip microcomputer U1 by R11, LCD U2 links to each other with single-chip microcomputer U1, and links to each other with warning circuit U4.See accompanying drawing 3.The course of work of the present utility model and principle of work, single-chip microcomputer U1 is under the support of software, the current value that is become by the fund data reduction on the TM card among the TM card reader U5 is stored among the data-carrier store U3, simultaneously, control circuit U6 opens motor valve 7 by single-chip microcomputer U1 drive controlling motor 5, at this moment, current enter from flow inlet 8, by water meter 6 and sensor, make water-flow signal be converted to pulse signal, store among the data-carrier store U3, along with the continuous increase of discharge, the data among the data-carrier store U3 are successively decreased.Data in data-carrier store U3 are decremented to the following of predetermined value and start warning circuit U4 in limited time, remind the water yield that the user purchases to run low; When data among the data-carrier store U3 were decremented to zero, motor valve 7 cut out, and stopped to supply water, and had only just can resume water supply after buying new TM card again.U5 is in sense data for the TM card reader, and the data that are about on the TM card are sent among the data-carrier store U3 and zero clearing, so that the TM card uses next time.Certainly, the prerequisite of use is the power supply power supply, and when power supply U9 was not enough, electric voltage observation circuit U7 gave single-chip microcomputer U1 with measured voltage, and motor valve 7 cuts out, and no longer supplies water, and needs to change power supply U9 at this moment, to guarantee to continue use.

The utility model is owing to adopt the single-chip microcomputer intelligent control technology, and its outstanding feature is to have changed traditional manual toll collection pattern according to the input automatic charging and the automatic control motor valve of flow signal.Make and realized first payment back water, pay the management mode of how many moneys, improved management level with how much water.The utlity model has automatic gauge discharge function, have functions such as self check and warning indication, LCD can show situations such as the water amount of buying, surplus.This utility model not only can reduce a large amount of managerial personnel, and has solved many problems that manual toll collection exists, for the modern management of water supply industry provides advanced guarantee.It is widely used in each water supply field of both urban and rural residents's daily life.
