Safe-cutoff IC card intelligent gas meter

Abstract

The invention discloses a safe-cutoff IC card intelligent gas meter and belongs to gas meters. The safe-cutoff IC card intelligent gas meter comprises a meter body. The meter body is provided with a gas inlet and a gas outlet. The gas inlet is provided with a cutoff valve. The meter further comprises a signal collection and processing circuit and a safe-cutoff IC card intelligent gas meter terminal microcomputer controller. The cutoff valve is connected to the safe-cutoff IC card intelligent gas meter terminal microcomputer controller through a cutoff valve control circuit. The signal collection and processing circuit is used for collecting volume of gas flowing the meter body in real time and transmitting the volume to the safe-cutoff IC card intelligent gas meter terminal microcomputer controller; when detected abnormalities, such as low flow leakage and high flow anomaly, occur to the meter body in output, the cutoff valve on the meter body can be closed in time, a warning is given out, burning or explosion caused by excessive gas leakage is avoided, and life and property safety of people is protected.

Description

technical field [0001] The invention relates to a gas meter, and more specifically, the invention mainly relates to a safety cut-off IC card smart gas meter. Background technique [0002] At present, most of the gas companies use IC card membrane gas meters and IC card smart gas meters and their gas sales management systems for business management. IC card membrane gas meters use IC cards as media to realize prepayment and related management. Function, the IC card smart gas meter has improved the function on the basis of the IC card membrane gas meter, which ensures the accuracy of measurement and the reliability of valve control. There is no effective and reliable technical means for safety management in the abnormal state of gas use safety. When the gas is in an abnormal state during use, leakage, fire, explosion, etc. may occur, which is not conducive to the safety management of the gas company, and also gives People's lives and property safety bring great hidden danger....
