Intelligent control gas meter

Abstract

The invention relates to an intelligent control gas meter. When a valve in the gas meter is opened, energy needed when the valve is closed is stored for the magnet displacement generated when the valve is opened; magnetic force is used for process control when magnets are at greater distances and magnetic attraction force is weak; the magnetic attraction force is used for switching off the power of the valve when the magnets are at closer distances and the magnetic force is strong; the intelligent control gas meter has uniform measurement readings conforming to the purpose of legislation of a metrological law; an electronic instruction is unconditionally compulsorily and continuously executed by a mechanical part and is irrevocable after being executed and completed; a circuit only instantaneously works to intelligently judge gas supply conditions in the process of each cycle of gas supply; preset gas supply amount is continuously completed when the gas supply conditions are not met, and the valve in the gas meter is automatically closed when electric power does not need supplying; and a motor in the meter is started to recover a control mechanism to a new gas supply state when the gas supply conditions are met. The intelligent control gas meter thoroughly eliminates the troubles brought by charging, management, and inconformity of the metrological law of intelligent gas meters and far-communication gas meters by the conventional non electrical quantity electrical measurement technology.

Description

technical field [0001] The present invention relates to a flow measuring device, more specifically, relates to a device capable of de-energized work, the circuit works instantaneously during the gas supply process, and intelligently judges the gas supply conditions. It is an intelligent control gas meter that can automatically shut off the valve in the gas meter without power supply. Background technique [0002] At present, there are mainly three kinds of public gas meters. The first type is a mechanical gas meter, the main mechanical gas meter is a membrane gas meter, the second type is an intelligent gas meter, and the third type is a remote gas meter. Smart gas meters and remote gas meters are mechanical / electronic devices composed of non-electrical measuring instruments and intelligent electronic circuits superimposed on mechanical gas meters. In terms of working principle, mainstream mechanical gas meters use the "volumetric method" to measure the volume of air flow p...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to solve many physical quantity measurement, electric measurement conversion and display problems caused by power supply, equipment damage, and connection line damage in the existing traditional smart gas meters and remote gas meters. The gas meter cannot work normally and stably when there is no power supply or the power supply is abnormal. The fundamental structural defect of reliable gas supply. The remote gas meter has defects in the inaccurate data caused by abnormal power supply and abnormal connecti
