Abstract
The utility model relates to a rotary-wing dry water meter using an IC card, composed of a control part, a metering part and an executive part. The utility model is characterized in that prepayment before water use is adopted; an IC card with purchased water quantity which is written in by a microcomputer charging management system can be purchased firstly, and then a water meter can be automatically opened by the operating part; after the prepaid fee is used up, the water meter can be automatically closed. The utility model solves the problems that common water meters can be metered by mechanical rotations, the meter can be checked and charged by a meter checker from house to house, which takes time and is troublesome, and can easily result in delayed payment. The utility model has the advantages of simple operation and easy maintenance, being convenient for the management of water supply industry.
Description
The utility model relates to a kind of water meter of the record controls water yield, particularly a kind of IC-card multi jet dry type vane wheel water meter.
Present normally used water meter generally all is mechanical, is to drive water meter machinery by the water yield of passing through to measure, again by showing on the dial plate, look meter and charge from house to house by the personnel of tabling look-up, not only time-consuming bothersome, and easily be in arrears with and pay dues, all make troubles for charge person or resident.
The purpose of this utility model is: provide a kind of and can overcome above-mentioned defective, and by the IC-card of resident elder generation to management of the use of water department purchase water, should block and insert in the water meter, can be by the switching of actual used water amount autocontrol valve, need not to look meter and charge, avoid being in arrears with and pay dues, realize " taking back water in advance earlier ", multiple service function is set simultaneously, overcome the defective of traditional mechanical formula water meter, the change passive management is active management, and easy for installation, safeguards simple, cost is low, and few IC-card multi jet dry type vane wheel water meter consumes energy.
Technical solution of the present utility model is: a kind of IC-card multi jet dry type vane wheel water meter, it is by metering units, control gear and topworks's three parts are formed, control gear comprises that data keep A, water meter pulse B, IC-card socket C, display D, driving circuit E, CPU microprocessor F, topworks comprises remote transmission device 1, solenoid valve 2, diaphragm 3, diaphragm gearing 4, piston 5, valve body 6, metering section comprises impeller 7, it is characterized in that: a remote transmission device 1 and solenoid valve 2 are equipped with in the top of valve body 6, one diaphragm 3 is housed in the valve body 6, a diaphragm gearing 4 is equipped with in the bottom of diaphragm 3, one impeller 7 is housed in the diaphragm gearing 4, be connected with a piston 5 below the diaphragm gearing 4, remote transmission device 1 connects water meter pulse B, water meter pulse B goes up and connects a CPU microprocessor F, is connected with IC-card socket C on the CPU microprocessor F, display D, data keep A and driving circuit E.
The utility model has the advantages that:
1. control section adopts integrated circuit, and direct current supply is safe in utilization, outage or replacing battery, and legacy data remains unchanged.
Scratch 2.IC card, has the magnetic field of not being afraid of as pre-payment water yield storage medium, can not forge, the information storage is big, uses permanent reliable.
3.IC the card multi jet dry type vane wheel water meter is novel in design, rationally, environmental suitability is strong, and solved the flooding of puzzlement water supply industry, buried, locked, a difficult problem that pressure, difficulty are made an inventory table.
4. water meter and valve unite two into one, and volume is little, and consumptive material is few, and cost is low, are convenient to install.
5. the liquid crystal display of data character is arranged on the screen, intuitive and convenient, the button on the control box is convenient to the ruuning situation that the user checks this table.
6. have antitheft, tamper, prompt functions, IC-card water meter and sales management hardware, combination of software form a whole set of equipment, and be easy to operate, and it is convenient to manage.
That the utility model will be further described is as follows below in conjunction with accompanying drawing:
Accompanying drawing 1 is the structural representation of IC-card multi jet dry type vane wheel water meter;
Accompanying drawing 2 is the circuit block diagram of control section.
The utility model is made up of control, metering and execution three parts, before the use, buy the IC-card that writes the water yield of being bought by the microcomputer charging administration system earlier, every the corresponding a slice IC-card of water meter sheet, IC-card can not be general, IC-card is inserted IC-card socket C, and then this IC-card multi jet dry type vane wheel water meter can be activated.During use, from IC-card, read in purchase volume by CPU microprocessor F and deposit in the data maintenance A, show by display D.User's water consumption is taken out water yield signal by the impeller 7 of metering section, the measurement unit of setting is sent the water meter pulse B that a signal is given control section by remote transmission device 1, the water yield of purchasing that CPU microprocessor F will read in simultaneously reduces by a measurement unit, when purchasing the water yield and be reduced to zero, CPU microprocessor F sends instruction and gives driving circuit E, driving circuit E produces the two ends that certain voltage acts on solenoid valve 2, the flexible pipe that connects pipe network and valve body 6 is opened, at this moment, the current of pipe network enter the top of the diaphragm 3 in the valve body 6 by flexible pipe, because the active area on the top of diaphragm 3 is greater than the active area of bottom, then Duo 1 multiplication of voltage than the bottom, therefore, pressure above the diaphragm 3 is greater than following pressure, and diaphragm 3 moves down, and moves down thereby drive diaphragm gearing 4, move down water meter is closed and drive piston 5, then stop to supply water.When IC-card re-enter purchase the water yield after, insert once more among the IC-card socket C, then the CPU microprocessor sends and opens signal to driving circuit E, driving circuit E produces the two ends that reverse voltage acts on solenoid valve 2, the hose passages that this moment, pipe network was connected with valve body 6 is hindered, but the epicoele above the diaphragm 3 communicates with atmospheric pressure, because the hydraulic pressure on the pipe network is greater than atmospheric pressure, pressure below the diaphragm 3 is greater than top pressure, then promoting diaphragm 3 moves up, move up thereby drive diaphragm gearing 4, water meter is opened water supply start and drive to move on the piston 5.So perseveration can be finished earlier pre-expense, the management method of back water, thereby the management level of raising tap water supply industry.
