Abstract
The invention discloses a water meter management system capable of realizing step water price, which comprises a processor unit, a display device, a flow counting module, a valve control circuit, a radio frequency (RF) card circuit, a power supply and an alarm circuit, wherein the flow counting module is connected with the power supply; the input port of the flow counting module is connected with a flow sensor; the output port of the flow counting module is connected with the display device and the RF card circuit respectively; the input end of the RF card circuit is connected with the flow counting module; the output end of the RF card circuit is connected with the processor unit; the RF card circuit is connected with an RF card water meter; the processor unit is connected with a valve control circuit; and the valve control circuit is connected with a valve. In the invention, a dividing point of two water volumes can be set to realize step charging, so the water volume consumed by a user can be limited reasonably; and thus, water is saved and waster resource waste is avoided.
Description
Technical field
The present invention is a kind of water meter management system that realizes stepped water pricing.
Background technology
The water rate of China is according to unified price at present, this has just caused the price of water and seriously deviating from of value, in some water-deficient areas, 1000 cubic metres of agricultural waters also cannot support upward the price of one bottle of mineral water, must cause the reduction greatly on the utilization factor like this, waste just, investigation shows to have only the raising when water rate can cause that just people are to water-saving attention.
Summary of the invention
The invention provides a kind of water meter management system that realizes stepped water pricing, thereby it can set the separation realization charge stage by stage of two water yields, thereby reasonable limits user's water consumption reaches water-saving function, avoids the waste of water resource.
The present invention has adopted following technical scheme: a kind of water meter management system that realizes stepped water pricing, it comprises processor unit, real device, the flow counting module, valve controling circuit, RF card circuit, power supply and warning circuit, the flowmeter module is connected with power supply, input port at the flow counting module is connected with flow sensor, the output port of flow counting module is connected with RF card circuit with display respectively, the input end of RF card circuit is connected with the flowmeter module, the output terminal of RF card circuit is connected with processor unit, be connected with RF card water meter on RF card circuit, processor unit is connected with valve controling circuit.
Described processor unit is an Atmel AVR169 single-chip microcomputer.Described display device is a LCD display.Described flow sensor is a Wei root sensor.Described RF card circuit comprises contactless identification system and card reader, and contactless identification system is connected with card reader, and contactless identification system is formed radio system by T5577 card and the two voltage comparator integrated circuit of LM393.Described RF card water meter adopts secondary power supply to detect.
The present invention has following beneficial effect: the present invention is provided with RF card circuit and RF card water meter, it can be provided with by price and the separation of RF card with three kinds of water rates, by the flow counting module water consumption is measured then, valve is controlled by processor unit according to the information in the card again, so just can realize charging stage by stage, thereby reasonable limits user's water consumption reaches water-saving function, avoids the waste of water resource.Processor unit of the present invention is an Atmel AVR169 single-chip microcomputer, and it has super low-power consumption, high-performance, high-speed, stable good characteristics.Flow sensor of the present invention adopts Wei root sensor, and it has no working power, no magnetic pole, contactless, corrosion-resistant and characteristics that the life-span is grown.Valve of the present invention adopts the electrodynamics suspension ball valve, and it has anti-lock, non-scaling, can realize that crushing is little, little, the characteristics such as power consumption is little, anticorrosion, anti-clogging of wearing and tearing.The present invention is provided with LCD display, and it has Chinese-character display function, reality accumulative total water consumption, the current residual water yield, when the inferior water yield battery electric quantity deficiency of purchasing, and the surplus water deficiency, easy to use
