Intelligent control water meter

Abstract

The invention relates to an intelligent quantitative control water meter. When a valve in the water meter is opened by separating magnets which attract with each other, energy required by closing a valve is registered in the displacement of the magnets generated when the valve is opened; magnetic force is used for quantitative control when the magnets are far away from each other and magnetic attraction force is weak, and the magnetic attraction force is used as power for closing the valve when the magnets are close to each other and the magnetic force is strong; the water meter has a unifiedmeasurement reading which conforms to the purpose of legislation of the metrology law; water supply and power supply are alternately performed, normal water supply is performed without the power supply, and the valve is automatically closed without electric energy when a quota is finished; a circuit is electrified for short time to intelligently judge, a motor in the meter is conditionally started and the valve is opened to recover the water supply; and the water meter is provided with an internal locking device for preventing the water meter from being illegally and nondestructively opened or disassembled. The intelligent quantitative control water meter has the advantages of simpleness, stability and reliability. The problems of the measurement, charging, management and measurement law of the intelligent water meter and a remote water meter caused by the conventional non-electrical quantity electrical testing technology are radically solved in a mechanical quantization and electronic equipment power-off working mode.

Description

technical field [0001] The present invention relates to a flow measuring device, more specifically, to an intelligent control water meter capable of automatically shutting off a valve in the water meter without supplying electric energy when the water supply reaches a predetermined value. Background technique [0002] At present, known public water meters, whether it is a volumetric mechanical water meter using a rotating measuring cup or a piston, or a speed-type mechanical water meter using a screw-type or rotor-type impeller, and water meters that are less used in other measurement methods, are all made of water meters. It consists of a watch case, a device for measuring the volume of water passing through it, a word wheel or gear for transmitting measurement values, and a word wheel or pointer disc for displaying and recording the instantaneous flow rate and cumulative flow rate of the measurement results. In order to prevent others from taking off the water meter cover ...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the smart water meter and the remote water meter developed for the traditional mode that the existing non-electric power measurement technology must rely on uninterrupted power supply to work normally are caused by power supply reasons, equipment damage, connecting wires, etc. Many metering display problems caused by power supply and equipment caused by damage, that is, the fundamental structural defects of smart water meters that cannot work normally and stably when there is no power supply or abnormal power supply, and reliable water supply. The defects that lead to inaccurate data normally, the problem that the remote water meter has no control function, provide a method that does not require power supply during water supply, and only needs electricity when water supply needs to be checked and collected or other water supply conditions need to be checked when water supply is fixed at one turn. If the water supply conditions are not met, the smart water meter and remote smart water meter technology solution that can automatically shut off the valve in the water meter without power supply

[0005] The second technical problem to be solved by the present invention is that the intelligent water meter in the prior art has the problem of dual display that cannot be uniformly measured and displayed, or a single display, that is, a water supply data has both mechanical readings and electronic readings. , to provide a unified water and water supply data solution
