Embodiment 1

[0021] The smart water meter has two functional modules: a flow counting module and a family anti-leakage module. Among them, the flow counting module is the same as other electronic water meters, and has the function of household water flow counting; the household anti-leakage module is composed of a single flow meter unit and a single flow count unit.

[0022] A home leak-proof smart water meter, which adds a timing unit and a flow counting unit on the basis of the existing electronic water meter, its structure and function are shown in Figure 1. The model of the traditional household electronic water meter is LXSZ-15E~50E intelligent cold water meter, the manufacturer: Chongqing Intelligent Water Meter Co., Ltd.; the water pipe 8 is connected to the traditional household electronic water meter, and the output of the valve 3 is connected to the faucet 9 .

[0023] The sensor 1 is responsible for converting the flow of water into an electrical signal and calculating its volum...

Embodiment 2

[0031] Embodiment 2: A household anti-leakage smart water meter. The smart water meter adds a household anti-leakage module on the basis of the existing electronic water meter. The module is composed of a timing unit and a counting unit, wherein the timing unit is used to calculate a continuous water consumption time , the counting unit is used to calculate a continuous water consumption, and judge whether there is a water pipe leakage by comparing these two values ​​with the preset threshold value. When it is judged that there is a leakage, the water meter will cut off the water source in time to prevent the spread of flood , After troubleshooting, use the reset switch 7 of the water meter to restore the water supply of the water meter.

[0032] The timing unit is realized by a single-chip microcomputer or other intelligent units.

[0033] The counting unit can be composed of the flow counting unit of the main water meter, or a storage unit can be used to store the current va...

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 CN1731462A) proposes to use the analysis of the rate of change of water use to judge whether there is a water leakage accident in the home. It is impossible to make correct judgments in the big process. Contents of the invention [00...
