Household water leakage prevention method and intellectual water meter

Abstract

The invention provides a family water-leakproof method and an intelligent water meter which adopts a switch which can judge whether the family continuous water supply time and the continuous water supply amount exceed an appointed threshold value in order to determine whether the water source is cut off. The water meter is only added with a timing unit and a counting unit on the basis of the existing electronic water meter, and has the simple structure and is practical and convenient. The invention has the following main steps: the timing unit calculates the one-time continuous water supply time; the counting unit calculates the one-time continuous water supply amount; respectively judging whether the one-time continuous water supply time and the one-time continuous water supply amount exceed the appointed threshold value, a pipeline is determined as the leakage if any value exceeds the appointed threshold value, and then the water source is cut off immediately; the invention is characterized in that the timing threshold value and the counting threshold value can be set as different leakproof grades according to different family requirements; in addition, the water meter has also a reset switch, and the water meter can be restored to supply water when the fault is eliminated. The invention can meet the requirements of common families preventing the flood.

Description

technical field [0001] The invention relates to a household water leakage prevention method and an intelligent water meter, belonging to the field of living appliances. Background technique [0002] In real life, water leakage often occurs due to aging, leakage, rupture of water pipes, taps that are not closed tightly or forgotten to close, etc., which will not only cause waste of water resources, increase water bills, but also endanger buildings and cause damage to houses and property losses, especially in residential buildings. In a densely populated area, a water leak may cause damage to adjacent and lower multi-units, causing inconvenience to residents' daily life. Such situations are common in real life. The patent (publication number CN 1731462A) proposes to use the rate of change of water use to judge whether there is a water leakage accident in the home. The disadvantage of this method is that it cannot distinguish the difference between the family's long-term water...

The patent (publication number CN 1731462A) proposes to use the rate of change of water use to judge whether there is a water leakage accident in the home. The disadvantage of this method is that it cannot distinguish the difference between the family's long-term water use (bathing, washing clothes) and water leakage, and when the water leakage accident is caused by Inability to make correct judgments in the process from small to large
