Description

The IC-card Automatic-controlled water-meter

Technical field

The utility model relates to a kind of water valve and operating means thereof, specifically, relates to a kind of IC-card Automatic-controlled water-meter.

Background technology

The management of the use of water method of existing tap water generally is to adopt the mechanical pointer water meter that the water that flows through water valve is measured, Running-water Company sends special messenger's counting cost by gas meter of calling, both wasted time and energy like this, the problem that has difficult charge again, even when water meter breaks down, measure inaccurate sometimes, can not accurately reflect user's water consumption, bring the certain economic loss to Running-water Company.

Summary of the invention

Exist and send special messenger's counting cost by gas meter and make and waste time and energy and the problem of difficult charge and the inaccurate problem of influence metering that breaks down in order to solve existing machinery pointer-type water meter, the purpose of this utility model, be that a kind of IC-card Automatic-controlled water-meter that need not manual metering and must the advance payment water rate can automatic ration supply water is provided, and make it be difficult for breaking down and accurate measurement.

Solution of the present utility model is as follows.Referring to Fig. 1 the utility model, the structure frame principle figure of machine one, it is by power circuit 1, IC-card and card reader 2, water valve control circuit 3, include the computer LCD 4 of flowmeter and sensor, electromagnetism water valve 5 and water route communicating pipe 6 connect and compose, wherein the output control terminal of IC-card and card reader 2 links to each other with the input control end of water valve control circuit 3, the calorific power signal output part of IC-card and card reader 2 and feedback signal input end join with the calorific power signal input part and the feedback signal output terminal of the computer LCD 4 that includes flowmeter and sensor respectively, the output control terminal of water valve control circuit 3 links to each other with the control end of electromagnetism water valve 5, the water inlet end of water route communicating pipe 6 and water side join with the water side 52 of electromagnetism water valve 5 and the water inlet end 41 that includes the computer LCD 4 of flowmeter and sensor respectively, the power output end of power circuit 1 respectively with IC-card and card reader 2, water valve control circuit 3 and include flowmeter and the power input of the computer LCD 4 of sensor links to each other so that dc supply to be provided.

The utility model with said structure is installed in the user when using, and the water inlet end 51 of electromagnetism water valve 5 should be connected with running water pipe, and the water side 42 that includes the computer LCD 4 of flowmeter and sensor is connected depotition cock 7.Its principle of work is as follows: when insertion in the deck of IC-card and card reader 2 is filled with the IC-card of certain calorific power, circuit can be read calorific power in full, and be transferred to the calorific power signal input part of the computer LCD 4 that includes flowmeter and sensor by its calorific power signal output part, with calorific power with limit the use of the water yield and be presented on the LCDs.Simultaneously, the input control end of the output control terminal output high level signal water-supply valve control circuit 3 of IC-card and card reader 2, make the output control terminal of water valve control circuit 3 export the control end that a control signal is given electromagnetism water valve 5, electromagnetism water valve 5 is opened, thereby allow user's water.If depotition cock 7 is turned on, then current through electromagnetism water valve 5, water route communicating pipe 6, include the water inlet end 41 and water side 42 of the computer LCD 4 of flowmeter and sensor, flow out from depotition cock 7.This moment is because the pulse sensing effect of flowmeter, the calorific power of LCD and limit the use of the water yield along with the increase of water consumption corresponding successively decreasing, and in time be presented on the liquid crystal display, and the numerical value that shows in time feeds back to the feedback signal input end of IC-card and card reader 2 with the calorific power on the deduction IC-card by its feedback signal output terminal.Like this, the utility model has been realized the control of water delivery and the metering and the demonstration of carrying capacity.

When the card reader 2 of IC-card is not inserted IC-card, though or insert IC-card but calorific power on the IC-card has been used up when being zero, the input control end of the output control terminal output low level signal water-supply valve control circuit 3 of IC-card and card reader 2 then, make the output control terminal of water valve control circuit 3 not carry control signal to give electromagnetism water valve 5, electromagnetism water valve 5 just can not be opened, just do not allow user's water, do not supply water yet even the user opens depotition cock 7.At this moment, the user only plugs the IC-card that is filled with calorific power, or buys the IC-card that is filled with calorific power to Running-water Company, could start electromagnetism water valve 5 and supply water.

The beneficial effects of the utility model are, owing to adopt intellective IC card technology and computer lcd technology, so user's water and metering thereof have been realized intelligent control and management, this has just saved numerous and diverse formality of charging by manual metering at present, has reduced handling cost.Because charge back water has also avoided the user to be in arrears with water rate earlier.It is reasonable in design, and is easy to use, safe and reliable, economic and practical, for the management of the use of water of tap water realizes that modernization provides a kind of sophisticated equipment.
