Intelligent water meter with water leakage monitoring function and its intelligent control method

Abstract

The invention discloses an intelligent water meter with a water leakage monitoring function and an intelligent control method thereof. There is a one-way valve with a rated pressure difference, and an auxiliary impeller is set between the one-way valve and the main body of the water meter, and the water flow that the auxiliary impeller passes through each revolution is a fixed known value. The water passing through the fine holes can be sprayed onto the auxiliary impeller and rotate the auxiliary impeller. The auxiliary impeller is provided with an inductor for sensing the rotation speed of the auxiliary impeller, and the inductor and the solenoid valve are respectively connected with the controller. The water meter can monitor the water leakage of the water pipe, and it has the effect of simple and fast monitoring logic and high monitoring accuracy.

Description

Technical field [0001] The present invention relates to the field of water meters, specifically to a smart water meter having a water leakage monitoring function and an intelligent control method thereof. Background [0002] At present, there are many kinds of water-saving devices or systems at home and abroad, which are widely used in agricultural irrigation, industrial production, household water, etc., from large agricultural irrigation systems to small flush toilets for household use, which reflect people's water-saving ideas everywhere. At present, there are many types of devices based on home water saving, such as water-saving toilets, water-saving faucets, water-saving washing machines, and water-saving control systems. However, there is no special solution to the problem of water waste caused by the water dragon not closing the drip leakage and the faucet forgetting to turn off the water. An unclosed faucet can drain 1 to 6 cubic meters of water a month; a leaking toilet ...

AI Technical Summary

Problems solved by technology

[0003] At the same time, in life, water leakage often occurs due to aging, leakage, rupture, 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. In a densely populated residential area, a water leak may cause damage to adjacent and lower multi-units, causing inconvenience to residents' daily life

Or in high-end hotels and other places, there may be floods caused by burst water pipes, which may seriously damage the high-end facilities in the hotel. Such situations are not uncommon in real life.

[0004] In response to the above problems, our company has applied for two corresponding invention patent applications, namely: "Comparison Document 1, ZL201510682895.6 patent name is water leakage protection device and its method" and "Comparison Document 2, ZL201610104966.9 patent name is "Water pipe micro-leakage monitoring device and micro-leakage monitoring method (applied but unpublished)", aiming at the above-mentioned problems, it solves the problems of micro-leakage and burst leak respectively. Among them, the technologies in the comparative document 1 are respectively It solves the problem of micro-leakage and its explosion, but there are the following problems in the monitoring of micro-leakage: 1. The judgment of micro-leakage is easily misjudged by the speed and accumulated time

2 It takes a long time to judge the micro-leakage, which will lead to a relative waste of water resources

[0005] As for the comparison document 2, it simply improves the micro-leakage, and realizes the monitoring by enlarging the water flow dynamics of the micro-leakage through the combination of the one-way valve and the fine hole. Relatively single; 2. Due to the problem of water quality, the pores are easy to block, which makes the maintenance frequency and difficulty high

[0006] At the same time, the above-mentioned comparative document 1 and comparative document 2 have a common problem, that is, they cannot be combined with a water meter and must be rear-mounted, which will increase the workload of their installation and cause inconvenience
