Problems solved by technology

[0002] At present, my country's water fee is based on a unified price, which has caused a serious deviation between the price and value of water. In some water-scarce areas, 1,000 cubic meters of agricultural water is not worth the price of a bottle of mineral water, which will inevitably lead to the use of The rate is greatly reduced, that is, waste. The survey shows that only when the water fee is increased can people pay attention to water conservation.

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 [0001] The invention is a water meter management system capable of realizing stepwise water prices. Background technique [0002] At present, my country's water fee is based on a unified price, which has caused a serious deviation between the price and value of water. In some water-scarce areas, 1,000 cubic meters of agricultural water is not worth the price of a bottle of mineral water, which will inevitably lead to the use of Greatly reduce on the rate, that is waste, survey shows, only when the raising of water rate can cause people to pay attention to saving water. Contents of the invention [0003] The present invention provides a water meter management system capable of realizing stepped water prices, which can set the dividing point of two water volumes to realize charging in stages, thereby reasonably limiting the user's water consumption, achieving the function of saving water, and avoiding the waste of water resources . [0004] The present inven...
