Intelligent fixed quantity water meter

Abstract

The invention relates to automatic shutdown of quantitative water supply, namely a smart quantitative water meter which can prevent from being disassembled by non-management-and-maintenance staff anda far-transmission type smart quantitative water meter. The invention adopts the way of alternative power supply for water supply and water meter circuits: supplying water when the power is cut off and supplying power when the water is cut off; turning off a valve when a circle of water supply is finished and turning on the valve for providing short-term power for circuits when collecting water charges; and the way is that: a valve, which can automatically turn off in a reverse driection without control nor power, is installed in a water meter without changing original installation length andposition, namely when the power is turned off, set water amount can be supplied and power for automatically turning off the valve is released, thus realizing that household electrical appliances can work after the power is turned off; various parts of the water meter are fixed to be a whole and a lock without a key hole is used in the water meter for wholly locking a meter shell and the various parts; control circuits are arranged in the water meter and the case of the water meter; a microelectronic circuit function block is arranged in the control circuit, which can receive command signals transmitted by various information mediums such as IC card, communication line, broadband network and the like and a mini-size motor in the water meter is controlled for conditionally turning on the valve or disassembling the water meter.

Description

technical field [0001] The invention relates to a water supply that can be quantitatively controlled, especially capable of detecting and measuring the flow of water and automatically shutting off quantitatively without external electrical energy and mechanical energy. The specific electrical signal transmitted, after identification, can conditionally start the micro motor in the meter, open the valve in the water meter, and restore the water supply; and can lock the water meter cover, watch case, valve, valve opening and closing control system, and circuit from the water meter The fastening is integrated, and even the front water pipe joint of the water meter can be covered, closed or semi-closed from above, and locked and fastened from the inside of the water meter, so as to prevent non-water supply management and maintenance personnel from opening or dismantling the water meter, water meter cover, valve cover, electrical appliances box smart quantitative water meter.

AI Technical Summary

Problems solved by technology

It can not only detect metering, but also use a single mechanical pointer / digital wheel to display the instantaneous flow and cumulative flow readings passing through the water meter, and can quantitatively control the amount of water flowing through the water meter; it can also display the available water volume of the water meter; it solves the existing problem Smart water meters and remote water meters have dual displays of electronic digital display and mechanical digital display or multiple displays of water consumption and water supply. Structural defects; It is encrypted and locked, and the water pipe joint in front of the water meter can be covered and closed or semi-closed from above to prevent non-administrative maintenance personnel from opening the water meter cover and valve cover by themselves, tampering with the internal parts of the meter, or changing the water meter by themselves after opening the water meter cover and valve cover. Reading, dismantling the water meter, electrical box, water pipe joint before the water meter; if attack: damage the power supply, disassemble the circuit, destroy the structure, etc., the water meter will automatically close the valve to stop the water supply without any power or external force after a quantitative supply, attack behavior The attacker has obviously damaged himself; a destructive attack on one's own property or living facilities has only loss but no gain, and it will not happen under normal circumstances; therefore, it has extremely high resistance to attack
