Abstract

The utility model provides a noncontact IC (Integrated Circuit) card prepayment water meter comprising a meter body, a water pipe, an electromagnetic valve, a flow sensor, a display device, a card reading unit, a control unit, a battery and a driving unit. The noncontact IC card prepayment water meter is characterized by further comprising an alarm which is connected with the control unit; the electromagnetic valve and the flow sensor are sequentially arranged in the water pipe; the electromagnetic valve is connected with the driving unit; the flow sensor, the display device, the card reading unit and the driving unit are connected with the control unit respectively; and the card reading unit is a radio frequency coil. The noncontact IC card prepayment water meter adopts a noncontact IC card instead of an IC card socket with low reliability and high failure rate, and the surface of the water meter has no openings, so that the waterproof performance of the prepayment water meter is greatly improved and the prepayment water meter can reliably work for long term; and when the prepaid water amount reaches the final certain amount, the control unit controls the alarm to produce a buzzing sound to warn a user of purchasing additional water amount in time, thereby guaranteeing the water consumption need of the user.

Description

A kind of Contactless type IC card prepaying water meter

Technical field

The utility model relates to instrument field, relates in particular to a kind of water meter.

Background technology

At present, the water meter in the town dweller family is progressively from traditional mechanical rotary-wing type wet water-meter to the prepay water meter transition with IC-card.Use the user of prepay water meter only need hold IC-card to the management of the use of water department purchase water yield, then IC-card is inserted into the water yield input that can realize water meter in the prepay water meter, the work of overcharging and pay the fees, adopt this prepay water meter can greatly reduce the workload of management of the use of water department, realized the three-in-one integrated function of checking meter, charge, controlling.Mechanical Contact between IC-card socket and the IC-card, card inserting mouth and contact are exposed to the water meter outside, the anti-attack of this structure water meter is poor, be subject to artificial destruction, can't guarantee regular fee, and the anti-adverse environment ability, trickle or dewfall are easy to make water to enter water meter by bayonet socket, therefore cause loose contact between IC-card and the deck, can not carry out normal information exchange between IC-card and the water meter, affect measurement accuracy even quit work; When the water yield runs low, can not in time purchase water by reminding user, cause the situation of cutting off the water supply suddenly to occur, bring inconvenience to the user.

Summary of the invention

In order to address the above problem, the utility model provides a kind of Contactless type IC card prepaying water meter, comprise the table body, be positioned at the water service pipe of table body bottom, be positioned at solenoid valve and the flow sensor of water service pipe, be positioned at display and the card reading unit on table body top, be positioned at the control module of table body inside, the battery that is connected with control module, driver element, characterized by further comprising alarm, described alarm is connected with control module, solenoid valve and flow sensor are installed in the described water service pipe successively, described solenoid valve is connected with driver element, described flow sensor, display, card reading unit, driver element all is connected with control module, and described card reading unit is radio-frequency coil.

Described control module is single-chip microcomputer.

Described display is liquid crystal display.

The beneficial effects of the utility model are: the utility model has been removed the IC-card socket that reliability is not high, failure rate is high, adopted non-contact IC card, water meter surface imperforation has improved the water resistance of prepay water meter greatly, and prepay water meter can be worked stably in a long term; And when the water yield remaining last when quantitative, control module control alarm is sounded a buzzer, prompting user is in time bought the new water yield, guarantees user's water demand.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is structured flowchart of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is further explained, such as Fig. 1, Fig. 2,1-table body, 2-water service pipe, 3-solenoid valve, 4-flow sensor, 5-display, 6-card reading unit, 7-control module, 8-battery, 9-driver element, 10-alarm.

Such as Fig. 1, shown in Figure 2, the utility model comprises table body 1, be positioned at the water service pipe 2 of table body 1 bottom, be positioned at solenoid valve 3 and the flow sensor 4 of water service pipe 2, be positioned at display 5 and the card reading unit 6 on table body 1 top, be positioned at the control module 7 of table body 1 inside, the battery 8 that is connected with control module 7, driver element 9, also comprise alarm 10, alarm 10 is connected with control module 7, solenoid valve 3 and flow sensor 4 are installed in water service pipe 2 successively, solenoid valve 3 is connected with driver element 9, flow sensor 4, display 5, card reading unit 6, driver element 9 all is connected with control module 7, control module 7 adopts single-chip microcomputer, card reading unit 6 is radio-frequency coil, and display 5 is liquid crystal display.

During use, first IC-card is pressed close to card reading unit 6, read the data of IC-card and sent into single-chip microcomputer and carry out data and process by card reading unit 6, the data message after the processing shows in display 5, and controls solenoid valves 3 by driver element 9 and do breakdown action.During water, single-chip microcomputer carries out water consumption measurement by the signal that flow sensor 4 sends, and remaining water volume that can be utilized shown in display 5, when the water yield remaining last when quantitative, single chip machine controlling circuit sends alerting signal to alarm 10, and alarm 10 prompting user of sounding a buzzer is when surplus water is zero, single-chip microcomputer is done closing motion by driver element 9 control solenoid valves 3, stops to supply water.The utility model has been removed the IC-card socket that reliability is not high, failure rate is high, has adopted non-contact IC card, and water meter surface imperforation has improved the water resistance of prepay water meter greatly, and prepay water meter can be worked stably in a long term; And when the water yield remaining last when quantitative, control module 7 control alarms 10 are sounded a buzzer, prompting user is in time bought the new water yield, guarantees user's water demand.
