Abstract
An intelligent IC card water meter can realize in charging different price at different consuming stage by setting stepped water price program for water consumption to satisfy the demands of scientific management and reasonable water supply at water shortage area.
Description
Technical field
The present invention relates to a kind of measuring instrument in a kind of hydrotechny field, relate in particular to a kind of prepayment intelligent IC-card water meter that can realize the staged metering and billing.
Background technology
Existing IC-card water meter, be by IC-card as medium, be written in the water meter user profile is disposable, be converted into water consumption according to the single water price of initial setting up and in water meter, prestore, the user consumes the water yield at every turn and deducts from the water yield that prestores, and is zero until the water yield.China is vast in territory, and the various places water resource differs greatly, and the water scarcity area utmost point need realize that quantitatively the branch valency supplies water, and existing water meter water price is single, can't accomplish the actual conditions requirement according to various places, in the different phase realization branch valency setting of water total amount.
Summary of the invention
Purpose of the present invention is at the existing single deficiency of water meter water price, a kind of prepayment intelligent IC-card water meter that can carry out the staged metering and billing of different valuation in the different consumption figure stages is provided, when the user consumes at every turn, in water meter, deduct according to the consumption amount of money of the different phase at real consumption place.
The objective of the invention is to be achieved through the following technical solutions, a kind of prepayment intelligent IC-card water meter of staged metering metering, comprise water meter, sensor in the water meter, data sampling circuit, IC-card, IC-card seat, the microprocessor, memory, IC-card read-write equipment, control circuit and the display device that have program curing is characterized in that the microprocessor that has program curing also carries out following steps:
(1) water ladder and stepped water pricing are set
(2) clock information is set
(3) reading card internal information and being stored in the table, is set minimum amount if read the amount of money, valve closing then, and liquid crystal display reminds the user to purchase water
(4) if the amount of money is not less than set minimum amount in the table, send out the valve instruction and read the flow information instruction to control circuit, and detect this water place ladder, if water consumption is not less than the set unit water yield, then sends instruction and deduct the consumption amount of money of place ladder and remaining sum is stored in the table to control circuit
(5) if last unit water yield of water between two set ladders, then after a ladder the unit water price as consumption the amount of money.
(6), then send out the valve instruction to control circuit if the amount of money is greater than set minimum amount in the table, and less than the unit water price of place ladder, and read flow information, when the consumption water yield reached the set unit water yield, valve was closed automatically, difference is stored in the table, and liquid crystal display reminds the user to purchase water
(7) if the amount of money closes threshold values smaller or equal to set prompting in the table, then valve is closed once automatically, and liquid crystal display reminds the user to purchase water, inserts the subscriber card valve and opens execution in step (4) again
(8) if set clock information equals the set time of metering and billing again, then re-execute above-mentioned steps
The present invention is by being provided with water ladder and stepped water pricing program, realized that the different consumption figure stages carry out different valuation, satisfied the needs of water scarcity area reasonable use of water, scientific management, helps using water wisely.

Embodiment
The present invention includes water meter, IC-card, IC-card seat, the microprocessor that has program curing, the storer singlechip chip of CPU, storer (or have), IC-card read-write equipment and control circuit, display device.Wherein, microprocessor is the hinge of The whole control circuit, it and be solidificated in wherein programmed control and reading and the switching of the topworks of valve IC-card.It is Microchip PIC16CF72 chip that above-mentioned microprocessor is selected model for use, and it is connected with the IC-card read-write equipment by pin P27,26, realizes the read-write operation of IC-card; Be connected with control circuit by pin P15,16, control circuit is connected the keying of operation valve topworks with motor and low noise high pulling torque gear.Display device is that a LCDs is connected with pin P12,13,14, can show the status information of IC-card.
IC-card is handled through encryption measures and is had fixing data layout, wherein contains overhead code, unique identifier, payment amount of money sign indicating number, reads and write operation for microprocessor, and the data on the IC-card can form the control to the water meter valve switching times.
When energising, microprocessor at first sends query statement to the IC-card read-write equipment, and whether inquiry wherein has card, if having, then whether the field headquarters data segment is not that sky and form are legal in the inquirying card, if illustrate that then the user has the right to use this product, otherwise then show corresponding error message, microprocessor sends instruction, the Igor Kanygin specified number is read in memory block (memory IC), and the setting unit water yield calculates each ladder unit's water price by the water price of the ladder at place at that time; Amount of money number in the table that reads if the amount of money that is read is set minimum amount (0), then sends instruction to control circuit, and liquid crystal display insufficient in amount information reminds the user to purchase water; If the amount of money number that reads is not less than set minimum amount (0), then send out the valve instruction to control circuit, drive the first order gear rotation of transmission group by the motor rotation of control circuit control driving gear set, thereby drive the rotation of final stage gear, the rotation that drives valve is opened or valve-off; And read the flow information instruction, and detect accumulative total water consumption place ladder; If this water consumption is not less than the set unit water yield, then sends instruction and deduct the consumption amount of money, and send instruction, the difference write store to storer to control circuit; If the amount of money then instructs valve opening greater than the unit water price of minimum amount (0) less than the place ladder in the table, valve is closed automatically when water consumption reaches the set unit water yield, reminds the user to purchase water, and will differ from write store; If the amount of money equals set pass valve amount of money value (20 yuan) in the table, then valve is closed automatically, reminds the user to purchase water, inserts the subscriber card valve again and opens again; If the unit water yield is between set two ladders, its consumption amount of money should be carried out back one ladder unit's water price: if table internal clock information equals the set time of metering and billing again, then send instruction to control circuit and re-execute above-mentioned steps.
