Abstract

The invention discloses an intelligent gas meter with a water inlet detection function. A terminal computer is arranged outside the intelligent gas meter. The intelligent gas meter comprises a base meter body, wherein a controller unit, an A / D conversion chip, a pressure sensor, a wireless transceiver module and a control valve are arranged inside the base meter body. The input end of the A / D conversion chip is connected with the pressure sensor, and the output end of the A / D conversion chip is connected with the input end of the controller unit. The information of pressure inside the base meter body generated when gas passes through is acquired by the pressure sensor, and the pressure information is converted into a corresponding detection signal which is then input into the terminal computer through the controller unit. The abnormal condition threshold ranges of pressure and periodical service life corresponding to the base meter body are preset in the terminal computer to be used for being compared with the pressure information contained in the pressure detection signal from the pressure sensor, and the control valve is controlled to be opened or closed through a valve driving circuit according to the comparison result so that a gas inlet valve of the gas meter can be opened or closed. When it is detected that water enters the gas meter, the gas meter gives an alarm or feeds the information back to a gas management system, so that loss is avoided.

Description

technical field [0001] The invention relates to the technical field of gas meters, in particular to an intelligent gas meter with the function of detecting water inflow. Background technique [0002] With the continuous improvement of the quality of life of residents, the consumption of natural gas is increasing day by day. In life, every household is equipped with a water heater and a gas meter. When the water heater inlet and the gas inlet are reversed or the gas meter is connected to the water pipe, the water flows through the gas meter, and then flows through the main network of the gas pipe and other users. in the gas meter. Once a gas leakage accident occurs, unavoidable losses will occur, which poses a potential threat to the gas safety of users, and also brings immeasurable potential safety hazards and economic losses to natural gas companies. Contents of the invention [0003] In view of this, the application provides a smart gas meter with water ingress detecti...
